Thanks for your answer. I have now tried to load the XLS without the KnowledgeAgent(see createKnowledgeBase() below). This time I got class loading problems( see stack trace below). This only happens when I load a XLS decision table, If I load a DRL rules file it runs fine without classloading issues. I use a custom classloader that is configured with the KnowledgeBaseConfiguration, I can see that drools is trying to load the rule classes from the custom classloader when I run DTABLE but not when I run DRL. ### STACKTRACE ### java.lang.ClassNotFoundException: Unable to load classA_rules_test.Rule_print_the_incoming_query_9 at org.drools.util.CompositeClassLoader.loadClass:110 at org.drools.rule.JavaDialectRuntimeData$PackageClassLoader.loadClass:540 at java.lang.ClassLoader.loadClass:247 at A_rules_test.Rule_print_the_incoming_query_9DefaultConsequenceInvoker.evaluate at org.drools.common.DefaultAgenda.fireActivation:1091 at org.drools.common.DefaultAgenda.fireNextItem:1029 at org.drools.common.DefaultAgenda.fireAllRules:1251 at org.drools.common.AbstractWorkingMemory.fireAllRules:708 at org.drools.common.AbstractWorkingMemory.fireAllRules:672 at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules:218 ### CREATION OF KNOWLEDGEBASE ### private void createKnowledgeBase() { KnowledgeBaseConfiguration kBaseConfig = KnowledgeBaseFactory .newKnowledgeBaseConfiguration(null, context.getClassLoader()); kBaseConfig.setOption(EventProcessingOption.STREAM); //kBaseConfig.setOption(MultithreadEvaluationOption.YES); //kBaseConfig.setOption(MaxThreadsOption.get(Runtime.getRuntime().availableProcessors() * 2)); KnowledgeBase kBase = KnowledgeBaseFactory .newKnowledgeBase(kBaseConfig); KnowledgeBuilderConfiguration bconf = KnowledgeBuilderFactory .newKnowledgeBuilderConfiguration(null, context.getClassLoader()); bconf.setProperty("drools.dialect.java.compiler", "ECLIPSE"); bconf.setProperty("drools.dialect.java.lngLevel", "1.6"); DecisionTableConfiguration dtableconfiguration = KnowledgeBuilderFactory.newDecisionTableConfiguration(); dtableconfiguration.setInputType( DecisionTableInputType.XLS ); PackageBuilderConfiguration pconf = (PackageBuilderConfiguration) bconf; pconf.setClassLoaderCacheEnabled(true); MVELDialectConfiguration conf = (MVELDialectConfiguration)pconf.getDialectConfiguration("mvel"); conf.setStrict(false); String compilerDumpDir = context.getCompilerDumpDir(); if (compilerDumpDir != null && !compilerDumpDir.isEmpty()) { pconf.setDumpDir(new File(compilerDumpDir)); } KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(kBase, bconf); kbuilder.add(ResourceFactory.newFileResource("/tmp/templatetest.xls"), ResourceType.DTABLE, dtableconfiguration); } From: Michael Anstis <michael.anstis@gmail.com<mailto:michael.anstis@gmail.com>> Reply-To: Rules Users List <rules-users@lists.jboss.org<mailto:rules-users@lists.jboss.org>> Date: Mon, 9 Jan 2012 09:18:51 +0100 To: Rules Users List <rules-users@lists.jboss.org<mailto:rules-users@lists.jboss.org>> Subject: Re: [rules-users] xls decisiontable -> unable to resolve method using strict-mode Have you tried load the XLS into a KnowledgeBase without using a KnowledgeAgent?

OK so the framework was looking for getRequest() before request() probably. Anyways it was a problem with the generation of MYHTTPD class that caused this the method was not visible like you hinted Wolfgang. Thank you guys for helping me!
