Re: [rules-users] java.lang.NoSuchFieldError during D5 upgrade

Was able to get pass through this. Am hit by other exceptions though. Will do some research on it and get back if I am not able to get pass the wall.

Got all the jars, made the code changes and resolved errors as I faced them. I am stuck on one which looks like an antlr error but don't know how it can be solved. Error I get is: Exception in thread "pool-2-thread-1" java.lang.NoSuchFieldError: m_memory at com.ssmb.muni.ordermanagement.engine.multiengine.implementation.DroolsEngineWrapper.init(DroolsEngineWrapper.java:63) at com.ssmb.muni.ordermanagement.engine.multiengine.DroolsEngineWrapperProxy$1.run(DroolsEngineWrapperProxy.java:148) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) at java.lang.Thread.run(Thread.java:595) I am using antlr-runtime-3.1.1.jar (one that comes with D5 binary package). The earlier version was using antlr-3.0ea8.jar. Is the antlr I am using correct or I need upgrade from runtime to the complete package or to a different version?
