Before you deploy PowerBuilder components to a WebSphere application server, customize the WebSphere Ant deployment options in the following files, located in %PB_SERVER_HOME%\config:
ws-ejb-deploy.xml
ws-install-app.xml
See your WebSphere documentation for details.
Sybase tests have found that deploying an EJB-JAR to WebSphere can be slower than deploying to JBoss or WebLogic. Check your application-server or server plug-in log file to verify the status of deployment in progress.
