When you build a project, the IDE compiles the BPEL source file and packages the BPEL file and web service artifacts, including WSDL and XSD files, into a JAR archive. You should add this project JAR file to a Composite Application project and then deploy it to the JBI server.
Follow this procedure to build a BPEL Module project:
In the Projects window, right-click the BPEL Module project's node and choose Build Project.
You can also perform a clean build by right-clicking the BPEL Module project's node in the Projects window and choosing Clean and Build Project.
Watch for the BUILD SUCCESSFUL message in the Output window.
