RE: [rules-users] java.lang.NoSuchMethodError

I have runned the small rule that I have created on a test example on eclipse, and it works fine. The problem is when I try to use the rule on a JBoss Portal. From what I’ve getter, the problem lies on conflict. Meaning that when I satisfy the Drools dependency with org.eclipse.jdt.core_3.2.0.v_642.jar or with ecj.jar, the portal gets unstable, because some times works fine and other times it gives the same error as the one bellow, but from a different origin. I believe the JBoss portal uses the same class, because I have found on the deploy file of the server the jar jasper-compiler-jdt.jar, which contains the same class. Some how, it gets on conflict with the other jar for the drools. I’m still trying to solve this. :-( ________________________________ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Steven Williams Sent: quarta-feira, 7 de Fevereiro de 2007 23:20 To: Rules Users List Subject: Re: [rules-users] java.lang.NoSuchMethodError Hi FBrum, You will find the org.eclipse.jdt.core_3.2.0.v_642.jar in your eclipse\plugins directory. cheers Steve On 2/7/07, Francisco Brum <francisco.brum(a)link.pt&gt; wrote: Hello everybody! I'm having the same problem that you had, but when I run the project from the JBoss Server and try do run the code with the JBoss rules, I get the error: java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem; at org.apache.commons.jci.compilers.EclipseJavaCompiler$2.acceptResult(EclipseJavaCompiler.java:237) at org.eclipse.jdt.internal.compiler.Compiler.handleInternalException(Compiler.java:415) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:352) at org.apache.commons.jci.compilers.EclipseJavaCompiler.compile(EclipseJavaCompiler.java:268) at org.drools.compiler.PackageBuilder.compileAll(Unknown Source) at org.drools.compiler.PackageBuilder.addPackage(Unknown Source) at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) I've downloaded the ecj.jar, which haves the org\eclipse\jdt\internal\compiler\CompilationResult.class with the getProblems() method, to the \lib folder of the server! But it seems that this ecj.jar haves some conflict, because there are times that it works and others it doesn't. So I have tried do look for the org.eclipse.jdt.core_3.2.0.v_642.jar In my org.drools.ide_3.0.5, but didn't found it. Don't know where to!! What should I do? Thanks in advanced for your attention FBrum.

What I said still holds true though - make sure the v642 jar is at the top of your runtime classpath.
