This task explains how to assemble a Web services-enabled enterprise
bean Java archive (JAR) file from a Web Services Description Language (WSDL)
file with an assembly tool.
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 to complete this task:
- An assembled enterprise bean JAR file that contains the Enterprise JavaBeans
(EJB) implementation and all classes that generate from the WSDL2Java command-line
tool when the role argument is develop-server and the container argument
is EJB.
- A WSDL file
- The complete webservices.xml, ibm-webservices-bnd.xmi and ibm-webservices-ext.xmi deployment
descriptors, and the 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
a WSDL file by following the actions in the steps for this task section.
Procedure
- Start
an assembly tool. The Eclipse assembly tools, Application
Server Toolkit (AST) 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 Project Navigator pane by clicking
the Project Navigator tab.
- Locate the project for the JAR file you just
imported in the Project Navigator pane.
- Expand the ejbModule entry so that the META-INF directory
is displayed. Expand the META-INF directory.
- Right-click the META-INF directory
and select 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 File > Import > File
system. Browse the WSDL file for this Web service and click Finish.
- Copy the JAX-RPC mapping file as specified
by the deployment descriptor <jaxrpc-mapping-file> element of
the webservices.xml file.
- Copy the webservices.xml, ibm-webservices-bnd.xmi and ibm-webservices-ext.xmi deployment
descriptors into the META-INF subdirectory in the same manner.
Results
You have the artifacts required to Web service-enable an 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
After assembling the
AddressBook.jar JAR filecontains
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/AddressBookSoapBindingImpl.class
