WSEJBDEPLOY From Ant: java.lang.NoClassDefFoundError:

Recently when trying to get an ant script to create an ejb.jar, I encountered the following with the WSEJBDEPLOY task. There are a few quirks with it, and it does work.

#1 Alter your ant task-def to look like:

<taskdef name=”wsejbdeploy”
classname=”com.ibm.websphere.ant.tasks.WsEjbDeploy”
classpath=”${websphere.home}/plugins/com.ibm.ws.runtime_6.1.0.jar” />

#2 Make sure you have the following properties set in your build.properties, or build.xml:

websphere.home = C:/Program Files/IBM/WebSphere/6.1/AppServer
user.install.root = C:/Program Files/IBM/WebSphere/6.1/AppServer

#3 Make sure you COMPILED everything under Ant using the IBM Compiler. Using the a Sun Compiler [ SUN Compiler JDK 1.5.0_11 ] produces the following error:

[wsejbdeploy] Error generating RMI code: RMIC Command returns RC = TMSEjb_Temp. The problems which stopped RMIC are displayed, and have also been recorded in the .log file in Exception in thread “main” java.lang.NoClassDefFoundError: sun/tools/util/CommandLine
[wsejbdeploy] at sun.rmi.rmic.Main.parseArgs(Main.java:209)
[wsejbdeploy] at sun.rmi.rmic.Main.compile(Main.java:166)
[wsejbdeploy] at sun.rmi.rmic.Main.main(Main.java:814)

When recompiled with the IBM/Java Compiler (below) IT WORKS!

java version “1.5.0”
Java(TM) 2 Runtime Environment, Standard Edition (build pwi32dev-20080315 (SR7))
