The Source Editor appears containing the Input file, Input.xml Note – If the Source Editor does not contain a tab for Input.xml, double-click the Input node in the Projects window to open the file.

5. From the Input.xml tab of the Source Editor, do the following: a. Locate the line: ?string? b. Replace ?string? with WS-BPEL USING NET BEAN, so that the line appears as follows: WS-BPEL USING NET BEAN c. From the NetBeans IDE menu bar, click Save All.

6. In the Projects window, double-click the Output node under Test -> TestCase1. Output.xml is opened in the Source Editor. Initially, Output.xml is empty until the first test run populates the file. 7. In the Projects window, right-click the TestCase1 node and choose Run from the pop-up menu. When the Overwrite Empty Output dialog box appears, click Yes to accept new output. The first test run populates the Output.xml file displayed in the Source Editor.

The test compares the output to the contents of the output file. Because the first run of the test has nothing to compare itself to, the first test fails. Subsequent test runs will compare their output with the contents of Output.xml and should succeed. 8. Run the test again. The test case is compared to the current output file and succeeds.

To Develop a J2EE Client Category : Java Projects : Java Application Software Required:   

Visual Studio 2005 SQL Server 2005 Netbeans IDE 6.0.1

PROCEDURE 1. Develop a .Net Web Service Step1:Creating a web service First let us create a new project in Visual Studio.NET for web service. Then add classes related to data access and write code for Web Service methods. 1. Start Visual studio.NET 2008/2005 2. Select File->New->Website. Select ASP.NET Web service as the type of the project and enter InventoryWS as the name of the project. Visual Studio provides Service.cs and Service.asmx files along with others. Delete these two files. 3. We add a new web service to the project using Website -> Add new item -> Web Service and enter name as InventoryService. Visual Studio creates InventoryService.aspx in root directory and InventoryService.cs in App_Code directory. We will write code for web service later. First let us create DAL to access database. Step2:Creating Data Access Layer Data Access Layer is set of classes used to access database. We centralize the entire data access to DAL. In this project we create two classes to represent data. I am using PRODUCTS table, which is created by me in MSDB database of Sql Server Express Edition. You have to do the same in your system. Create PRODUCTS table with the following structure. PRODID - int (Primary key) prodname - varchar(50) price - money qoh - int remarks - varchar(200) catcode - varchar(10)

Add some rows to PRODUCTS table. Add a class to the project using Website-> Add New Item -> Class and enter name as Product. Here is the code for Product.cs. using System; using System.Web.Services; using System.Runtime.Serialization; 2 4


&


e g a P

public class Product { private int prodid, qty; private string name, remarks; private double price; public int Qty { get { return qty; } set { qty = value; } } public int Prodid { get { return prodid; } set { prodid = value; } } public string Remarks { get { return remarks; } set { remarks = value; } } public string Name { get { return name; } set { name = value; } } public double Price { get { return price; } set { price = value; } } } Add connection string in connectionStrings section of web.config as follows. Add Database.cs class and enter the following code. using System.Web.Configuration; public class Database { public static string ConnectionString { get 3 4


&


e g a P

{ return WebConfigurationManager.ConnectionStrings["msdbcs"].ConnectionString; } } } Now create ProductDAL, which contains static methods for operations related to PRODUCTS table as follows. using System; using System.Data; using System.Data.SqlClient; using System.Collections.Generic; public class ProductsDAL { public static List GetAllProducts() { SqlConnection con = new SqlConnection(Database.ConnectionString); con.Open(); SqlCommand cmd = new SqlCommand("select * from products", con); SqlDataReader dr = cmd.ExecuteReader(); List products = new List(); while (dr.Read()) { Product p = new Product(); p.Prodid = (int)dr["prodid"]; p.Name = dr["prodname"].ToString(); p.Remarks = dr["remarks"].ToString(); p.Qty = (int)dr["qoh"]; p.Price = Convert.ToDouble(dr["price"]); products.Add(p); } dr.Close(); con.Close(); return products; } public static Product GetProduct(int prodid) { SqlConnection con = new SqlConnection(Database.ConnectionString); con.Open(); SqlCommand cmd = new SqlCommand("select * from products where prodid = @prodid", con); cmd.Parameters.AddWithValue("@prodid", prodid); SqlDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { Product p = new Product(); p.Prodid = (int) dr["prodid"]; p.Name = dr["prodname"].ToString(); 4 4


&


e g a P

p.Remarks = dr["remarks"].ToString(); p.Qty = (int) dr["qoh"]; p.Price = Convert.ToDouble (dr["price"]); return p; } else // product not found return null; } } Step 3: Using DAL in Web Service Now let us write code in web service, which makes use of DAL. It is always better you separate data access code into DAL so that other parts of the application do not depend on data access. They access database through DAL. Write the following code in InventoryService.cs. using System; using System.Web.Services; using System.Collections.Generic; [WebService(Namespace = "http://www.srikanthtechnologies.com/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class InventoryService : System.Web.Services.WebService {

[WebMethod( Description ="Returns Details Of All Products")] public List GetAllProducts() { return ProductsDAL.GetAllProducts(); } [WebMethod(Description = "Returns Details Of A Single Product ")] public Product GetProduct(int prodid) { return ProductsDAL.GetProduct(prodid); } } Now we are through our web service creation. Select web service - InventoryService.asmx and select View In Browser option from context menu (right click). From the page displayed in browser, click on methods and invoke them to test them. Step 5: Custom classes and WSDL Click on Service Description link and you get WSDL for the web service. The following section in that is of interest. 5 4


&


e g a P

Product class is taken as complexType and its members are placed as sub elements. Collection of Products is taken as an ArrayOfProduct. When you need to access this web service from Java application, we create proxy in Java. Product element will become a class in Java and ArrayOfProduct becomes another class that contains a List of product objects. So, WSDL contains details about custom classes so that clients can generate these classes again on the client. 2.Develop a J2EE Client Step 1:Creating Proxy in Java Now, let us create a proxy in Java to access InventoryService Web Service. 1. Start NetBeans IDE 6.5. 2. Select File->New Project. Select Java in category and Java Application in projects. Click on Next. 3. Enter InventoryClient as the name of the application. Change name of the class in Create Main Class option to Client 4. Click on Finish. 5. Select InvenotryClient project in Projects window. Right click to invoke context menu. Select New->Other. Select Web service in categories and Web Service Client in File Types. 6. In the next window, select WSDL URL radio button (as shown below) and enter the URL at which InventoryService is running. Click on Finish. NetBeans creates required classes to access web service.

6 4


&


e g a P

Step2 :Write code in Java to call web service Once proxy is created then we can write code to access web service methods from Java. In fact, NetBeans can do that for you. Follow the steps given below. 1. Open Client.java 2. Go into main function and click on right button. From context menu select Web Service Client Resources -> Call Web Service Operation... 3. A window pops up with operations in the web service (shown below).

7 4


&


e g a P

Select GetProduct in InventoryServiceSoap12 section. NetBeans automatically writes code for you. Just assign product id 100 to prodid and change code regarding output, to complete the code. try { // Call Web Service Operation com.srikanthtechnologies.InventoryService service = new com.srikanthtechnologies.InventoryService(); com.srikanthtechnologies.InventoryServiceSoap port = service.getInventoryServiceSoap12(); // TODO initialize WS operation arguments here int prodid = 100; // TODO process result here com.srikanthtechnologies.Product result = port.getProduct(prodid); System.out.println( result.getName()); } catch (Exception ex) { // TODO handle custom exceptions here } Lines in bold are modified by me. The rest is provided by NetBeans. That's all you have to do to call web service created in .NET from Java. 8 4


&


e g a P

As you can see, NetBeans created a class Product for which information is provided in WSDL. Follow the same steps to call GetAllProducts method. Change the code as follows. try { // Call Web Service Operation com.srikanthtechnologies.InventoryService service = new com.srikanthtechnologies.InventoryService(); com.srikanthtechnologies.InventoryServiceSoap port = service.getInventoryServiceSoap12(); // TODO process result here com.srikanthtechnologies.ArrayOfProduct result = port.getAllProducts(); List products = result.getProduct(); for(Product p : products) { System.out.println( p.getName() + " : " + p.getPrice()); }

} catch (Exception ex) { // TODO handle custom exceptions here } 4. Now, run Client.java to see whether details of products are displayed from Java program.

Result : Thus the client for accessing the .Net web service is develop and implemented successfully. 7. Develop a .NET client to access a J2EE web service. Aim:

8. Develop and execute WS-BPEL V2.0 business processes using the Eclipse BPEL plug-in Aim: To Develop and execute WS-BPEL V2.0 business processes using the Eclipse BPEL plug-in Software Required 1. Java™ V5.0 or later 2. Tomcat V5.5 or later 3. Eclipse V3.3.x with the following plug-ins installed: o EMF V2.3.x o GEF V3.3.x o DTP STK V1.5.x Creation of a simple BPEL process In this section, we create a simple BPEL process and try running it in ODE. The process merely performs simple string manipulation. Keep in mind that it is just a simple example, and you can create much more complex processes using the WS-BPEL V2.0 specification. Eclipse BPEL editor To create a simple BPEL process, run Eclipse and click File > New > Other menu item, select the BPEL 2.0 -> BPEL Project option and create a new BPEL project called HelloWorld. Once the project is created, you are ready to create your first BPEL process. Click File > New > Other menu item again and select the BPEL 2.0 > New BPEL Process File option to start with the BPEL process creation wizard, Figure 1. Create a BPEL process file

Let's create a synchronous process also called HelloWorld. On the next page of the wizard, you should choose BPEL process files location — just choose the project created before and click Finish. The sample process will be created. Figure 2. Creating a synchronous process

9 5


&


e g a P

As shown, the newly created process has two internal BPEL variables — input and output — and a sequence with one receive and one reply element. The receive block is responsible for receiving input BPEL process data and for initialization of the variable input. Similarly, the reply block is aimed at outputting BPEL process data using the output variable. Also during the BPEL process creation, the wizard created a WSDL file. This file describes input and output data types and a port type that represents the BPEL process. Both input and output data types simply contain single string fields. We're ready to add some data manipulation into our process. To do so, drag and drop an Assign block right between the receiveInput and replyOutput blocks. Figure 3. Drag and drop an Assign block

Once the assign block is placed, right-click the Assign block and choose the Show In Properties context menu item to show the Properties view and select the Details tab. The Assign block should initialize the output variable with an initial XML tags structure. It is the common procedure required by most of BPEL processing engines. Click the New button on the Detail tab to start creation of the first assign procedure. Select the Fixed Value element in the From select box and enter following lines into the text area: >tns:HelloWorldResponse xmlns:tns="http://www.ibm.com/wd2/ode/HelloWorld"> >tns:result/> >/tns:HelloWorldResponse> 0 6


&


e g a P

Next, select the Variable element in the To select box and choose the output/payload variable in the variables tree, as shown below. Figure 4. Initializing output variables

When the output variable is initialized, we can create a new assign procedure. For the sample process, this procedure gets a string value from the input variable, concatenates it with the "Hello" greeting and assigns the result to the output variable string field. For this click the New button and choose the Expression value in the From select box. In the text box displayed below, enter the following expression: concat("Hello ", $input.payload/tns:input). In the To section, select the output/payload/tns:result variable, as shown below. Figure 5. Selecting output/payload/tns:result

The Assign block is ready. As you can see, the Eclipse BPEL plug-in provides XPath V1.0 highlighting and code completion features to simplify creation of XPath queries. (See Resources to learn more about XPath.) WSDL file changes The WSDL file for a BPEL process should describe the types used in the BPEL process as well as port types, bindings, and services for your process. The WSDL automatically created by the wizard already contains a port type and in order to make the process functional, we need to create binding and service for it. Open the WSDL file in the respective editor and see the port type graphical definition. Figure 6. See the port type graphical definition

1 6


&


e g a P

To create a Web service binding, right-click any free area in the WSDL editor and choose the Add Binding option. In the Properties view rename the newly created binding to HelloWorldBinding and select HelloWorld as the port type for the new binding. Click the Generate Binding Content button to bring up the Binding Wizard dialog. Figure 7. The Binding Wizard dialog

Select SOAP protocol in the Protocol select box, check the document-literal option in the SOAP Binding Options section and click Finish. Figure 8. Binding options

After the binding is created, right-click a free area of the WSDL editor and choose the Add Service menu item to create a new one with the name HelloWorldService. Then specify HelloWorldPort 2 6


&


e g a P

for the binding's port name and the URL http://localhost:8080/ode/processes/HelloWorld for its address. Also select HelloWorldBinding as the binding for the newly created service. Figure 9. HelloWorldBinding

Our WSDL file is ready to be deployed into ODE application. Deployment descriptor The last thing we need to do before our process is ready for deployment is create an ODE descriptor. The descriptor must have the name deploy.xml and must be placed in the same directory where the BPEL and WSDL files are stored. Just create a new deploy.xml text file and put the following content there. Listing 1. Creating a deploy.xml text file

>?xml version="1.0" encoding="UTF-8"?> >deploy xmlns="http://ode.fivesight.com/schemas/2006/06/27/dd" xmlns:pns="http://www.ibm.com/wd2/ode/HelloWorld" xmlns:wns="http://www.ibm.com/wd2/ode/HelloWorld"> >process name="pns:HelloWorld"> >active>true>/active> >provide partnerLink="client"> >service name="wns:HelloWorldService" port="HelloWorldPort"/> >/provide> >/process> >/deploy> The descriptor specifies the list of process and services for a deployable unit. Back to top Usage of BPEL process Now, when the HelloWorld BPEL process is ready, we can deploy it into the ODE application and test it. Deploy BPEL process into ODE ODE supports hot-deployment of BPEL processes. To deploy the process created in previous sections, just copy the folder containing all the process's files into the webapps/ode/WEBINF/processes directory of your Apache Tomcat where ODE was deployed. To monitor deployment process, you can look into the log file logs/catalina.out in the Tomcat root directory for any new entries. An easy way to test the deployed process is to use the Eclipse Web Services Explorer tool. Rightclick your HelloWorld WSDL file and select Web Services > Test with Web Services Explorer pop-up menu item. Eclipse will start the Web Services Explorer test tool. Using this tool, enter some text to the input parameter and invoke the P rocess operation. As shown in Figure 10, the Web service returns the greeting to the text you just entered. Figure 10. Invoke a WSDL operation 3 6

e g a P

Creation of a BPEL process client When we have the Web service that executes the BPEL process, we can integrate this process into a client application. Let's use Eclipse WTP plug-in to generate an Axis-based Web services client. Before generating the client code, you need to add your Tomcat server in the list of Eclipse servers. Click File > New > Other menu item and select the Server option from the list. Then, go through the wizard steps to create a new Tomcat server for your Eclipse workspace. Once the server is created, right-click the WSDL file and select Web Services > Generate Client pop-up menu item. This action starts the Web Service Client wizard, which generates a new project with classes required for work with your Web service. Figure 11. Setting up the Web service client

4 6


&


e g a P

To work with the generated files, use the code similar to the following. Listing 2. Creating a Web service client

HelloWorldServiceLocator locator = new HelloWorldServiceLocator(); HelloWorldRequest hwRequest = new HelloWorldRequest(); hwRequest.setInput("developerWorks!"); HelloWorldResponse hwResponse = locator.getHelloWorldPort().process(hwRequest); String output = hwResponse.getResult(); After the code is executed, the output variable should contain the result of the BPEL process work. Back to top ODE Management API ODE provides access through Web services to some of the applications management functionality. By using it, you can control processes deployed in ODE and their instances, which are currently executed on the server. All operations are described in the pmapi.wsdl file located in the folder webapps/ode/WEB-INF of your Tomcat application. Unfortunately, pmapi.wsdl uses the old RPC document style, and it is difficult to use it using the Eclipse Web Services Explorer test tool, for example. 5 6


&


e g a P

The best way to access the Management API is to use the Axis2 libraries. In particular, use the ServiceClientUtil class, which is supplied by the ode-axis2 library. Axis2 depends on other libraries, including Xerces, Stax, etc. Most of them are included into the ode.war archive, so you can add it into your project dependencies. The following code demonstrates how to extract information about the current process instances. Listing 3. Extracting information about current process instances

ServiceClientUtil client = new ServiceClientUtil(); OMElement msg = client. buildMessage("listAllInstances", new String[] {}, new String[] {}); OMElement result = client.send(msg, "http://localhost:8080/ode/processes/InstanceManagement"); List>ProcessInfo> processes = new ArrayList>ProcessInfo>(); Iterator>OMElement> i = result.getChildElements(); while (i.hasNext()) { OMElement omInstanceInfo = i.next(); OMElement omProcessName = omInstanceInfo.getFirstChildWithName( new QName("http://www.apache.org/ode/pmapi/types/2006/08/02/", "process-name")); OMElement omStatus = omInstanceInfo.getFirstChildWithName( new QName("http://www.apache.org/ode/pmapi/types/2006/08/02/", "status")); OMElement omStarted = omInstanceInfo.getFirstChildWithName( new QName("http://www.apache.org/ode/pmapi/types/2006/08/02/", "dt-started")); OMElement omLastActive = omInstanceInfo.getFirstChildWithName( new QName("http://www.apache.org/ode/pmapi/types/2006/08/02/", "dt-last-active")); ProcessInfo process = new ProcessInfo(); process.setProcessName(omProcessName.getText()); process.setStatus(omStatus.getText()); process.setStarted(omStarted.getText()); process.setLastActive(omLastActive.getText()); processes.add(process); } The example uses the axiom library to retrieve information and store it as the list of ProcessInfo objects. They can be used from any other part of your application. Back to top ODE event listener ODE allows you to develop listeners for any action inside an ODE application, such as starting and stopping process instances. To create your own event listener, you need to implement the org.apache.ode.bpel.iapi.BpelEventListener interface defined in the ode-bpel-api.jar library. The 6 6


&


e g a P

following code demonstrates a simple implementation that prints to the standard output-stream incoming events and invocations of the startup() and shutdown() listener methods. Listing 4. The startup() and shutdown() listener methods

/** * {@inheritDoc} */ public void onEvent(BpelEvent event) { System.out.println(event); } /** * {@inheritDoc} */ public void startup(Properties arg0) { System.out.println(this.getClass() + " startup"); } /** * {@inheritDoc} */ public void shutdown() { System.out.println(this.getClass() + " shutdown"); }

Once a listener class is ready, you need to put it into the ODE classpath (you can put a JAR file with your listener class into the webapps/ode/WEB-INF/lib Tomcat directory). You also need to create the webapps/ode/WEB-INF/conf/ode-axis2.properties property file and add the following line there: ode-axis2.event.listeners=com.ibm.wd2.bpel.eventlistener.WD2EventListener The name of your listener class may differ from the one above.
