Debugging

[customer]

I have imported the source code to EA and have filled the Build, Test, Execute Scripts dialog as shown below:

Build cmd:
javac -g -classpath C:\Debugging\java\classes;C:\Debugging\java\lilbraries\semiotek.jar;C:\Debugging\java\lilbraries\xerces.jar;C:\Debugging\java\lilbraries\opencsv-1.6.jar Start.java

Run:
java -cp c:\Debugging\java\classes;C:\Debugging\java\lilbraries\semiotek.jar;C:\Debugging\java\lilbraries\xerces.jar;C:\Debugging\java\lilbraries\opencsv-1.6.jar; Start <param1> <param2>

Vars:
jre=C:\Program Files\Java\jdk1.5.0_09\jre

Debug:
Start <param1> <param2>

I am able to execute Build and Run without any problem, but debugging is not working. I've tried various versions for Debug, including entering the same text as for Run and always get only the same little window saying:
"Debug Target Not Found (check package settings)"
Any help would be much appreciated.
Thanks
