[rules-users] rule compilation problems

Hi all, I am new to JBoss. I just finished making my first program with Rules and it works fine, but when I try to integrate all that into my web application (using Jetty), I get the following error: [java] java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems() [Lorg/eclipse/jdt/core/compiler/IProblem; [java] at org.apache.jasper.compiler.JDTCompiler$2.acceptResult(JDTCompiler.java:341) [java] at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:417) ... I tried to fix the problem with: conf = new PackageBuilderConfiguration(); conf.setCompiler(PackageBuilderConfiguration.JANINO); ... PackageBuilder builder = new PackageBuilder(conf); builder.addPackageFromDrl(new StringReader(rule.getText())); ruleBase.addPackage(builder.getPackage()); as in http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesTomcat but it's not working either. Same message. Can you help me? Thanks G. Arias del RIo
