[rules-users] class loading issue with websphere 6.1

posting it again after successfule subscription. I have deployed my application on websphere 6.1, which contains Rule engine as one of the module using JBoss Rule 3.0.1. When i am trying to invoke drools api from my class ==================================== final PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(new StringReader(drl)); ==================================== it throws this exception: 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(E clipseJavaCompiler.java:237) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:335) at org.apache.commons.jci.compilers.EclipseJavaCompiler.compile(EclipseJ avaCompiler.java:268) at org.drools.compiler.PackageBuilder.compile(Unknown Source) at org.drools.compiler.PackageBuilder.compileRule(Unknown Source) at org.drools.compiler.PackageBuilder.addRule(Unknown Source) at org.drools.compiler.PackageBuilder.addPackage(Unknown Source) at org.drools.compiler.PackageBuilder.addPackageFromDrl(Unknown Source) I have checked that class org.eclipse.jdt.internal.compiler.CompilationResult is available with my application war in core-3.2.0.666.jar (which is part of drools distributable) and it has getProblems() method also. any help will be greatly appreciated. -- View this message in context: http://www.nabble.com/class-loading-issue-with-websphere-6.1-tf3027390.ht...
