You can assemble a Web service-enabled enterprise bean Java archive
(JAR) file with an assembly tool using artifacts generated from tooling.
Before you begin
You can assemble Java-based Web services modules with assembly tools provided with WebSphere Application Server.
You must configure the assembly tool before you can use it.
You
need the following artifacts that are generated from the
WSDL2Java command-line
tool to complete this task:
- An assembled enterprise bean JAR file that is not enabled for Web services
- A compiled Java class for the service endpoint interface
- A Web Services Description Language (WSDL) file
- The complete webservices.xml,ibm-webservices-bnd.xmi,
and ibm-webservices-ext.xmi deployment descriptor, and Java API for
XML-based remote procedure call (JAX-RPC) mapping file.
About this task
Assemble a Web services-enabled enterprise bean JAR file from Java
code by following the actions in the steps for this task section.
Procedure
-
Start an assembly tool.
The Eclipse assembly tools, Application Server Toolkit and Rational® Web Developer provide
a graphical interface for developing code artifacts, assembling the code artifacts
into various archives or modules and configuring related J2EE Version 1.2,
1.3 or 1.4 compliant deployment descriptors.
- Click File > Import to import
the enterprise bean JAR file into the assembly tool.
- Open the J2EE perspective by clicking Windows >Open
Perspective > Other > J2EE.
- Switch to the Navigator pane by clicking
the Navigator tab.
- Locate the project containing the JAR file
that you just imported in the Navigator pane.
- Expand the ejbModule entry until the META-INF directory
display is displayed. Expand the META-INF directory.
- Right-click the META-INF directory
and click New > Folder. Create a subfolder named wsdl in
the META-INF directory.
- Copy the WSDL file to the META-INF\wsdl directory
by right-clicking the wsdl directory and click Import > File
system. Browse the WSDL file for this Web service and click Finish.
- Copy the JAX-RPC mapping file, webservices.xml, ibm-webservices-bnd.xmi,
and ibm-webservices-ext.xmi files into the META-INF directory.
- Import the service endpoint interface class
so that the service endpoint interface package begins in the ejbModule directory.
You can import either the source file or a compiled class file. If you
import the source file it automatically compiles.
Results
You have the artifacts required to Web service-enable an Enterprise
JavaBeans (EJB) module for Web services. The artifacts are added to the JAR
file. Now you need to configure the deployment descriptors so that you can
deploy the Web service into the WebSphere Application Server run time environment.
Example
The
AddressBook.jar JAR file contains the following files
after assembly. The files added in this task are in bold. These files include
the WSDL file, the deployment descriptors, and the JAX-RPC mapping file.
META-INF/MANIFEST.MF
META-INF/ejb-jar.xml
addr/Address.class
addr/AddressBook_RI.class
addr/AddressBookBean.class
addr/AddressBookHome.class
addr/Phone.class
addr/StateType.class
addr/AddressBook.class
META-INF/wsdl/AddressBook.wsdl
META-INF/ibm-webservices-bnd.xmi
META-INF/ibm-webservices-ext.xmi
META-INF/webservices.xml
META-INF/AddressBook_mapping.xml
What to do next
Assemble the EAR file so that you can deploy the EAR file into WebSphere
Application Server.
