i have a problem while running the build.xml using the ant script(i.e ant build.xml)and got the below mentioned error... any help would be appreciated, as i was trying to solve this for the past 2days ... using weblogic 9.0
Make sure you are pointing to the weblogic.jar that is part of your 9.x install... not just a copy of that jar moved to another directory. There are a number classpath manifest entries that weblogic.jar has and uses during the execution of appc and I suspect they are not being loaded properly.
For example add the following to your build.xml classpath ref: C:\bea\weblogic91\server\lib\weblogic.jar
