how to run ant scripts programtaclly in smf bundle in WSSD
5.1.2

Hi,
I am using WSSD 5.1.2 and tring to submit a bundle programatically. I run ant
build file in one bundle and try to submit another bundle bu running this buid
file. The code I am tring to run is similar to the code given in the site 
"http://www-128.ibm.com/developerworks/websphere/library/techarticles/0502_
gawor/0502_gawor.html" in a bundle, but it gives classdefnotfoexceptions on
this. 

java.lang.NoClassDefFoundError: org/apache/tools/ant/Project
	at oulu.info.rmtsvcrunner.Runner.antRun(Runner.java:38)
	at oulu.info.rmtsvcrunner.Runner.run(Runner.java:55)
	at java.lang.Thread.run(Thread.java:513)
I included java files in the budle build but did not work out. If any one can
suggest a solution it would be a great help.
Thank you.

In the ant buid file I have prepared I tried two approches. 
when I try to run the ant build file out of the IDE I recieve thie Null pointer
exception arrises from the follwing
<smfbd.submitJarBundle bundlepath="/HelloWorld"
replace="true">
ant tasks bundle path element. Can any one suggest a way to over come one of
this problems. the ant build files works fine with out any exception when I run
them using the "Run ant" option provided by the IDE.
