[jboss-user] [jBPM] - Error debugging on clean install

Chris Nash [http://community.jboss.org/people/code_monkey] created the discussion "Error debugging on clean install" To view the discussion, visit: http://community.jboss.org/message/623045#623045 -------------------------------------------------------------- Hi, I've installed jBPM5.1 on a bare OS: Windows Server 2003. It had nothing else installed on it previously. I installed the latest version of the Java JDK and Ant and set them up appropriately (JAVA_HOME, ANT_HOME, both \bins in the Path). I ran ant install.demo. So far so good. In Eclipse, I tried to debug the first sample app: evaluation | ProcessTest.java. I got this error: org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'     at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:277)     at org.drools.compiler.PackageBuilderConfiguration.buildDialectConfigurationMap(PackageBuilderConfiguration.java:262)     at org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderConfiguration.java:175)     at org.drools.compiler.PackageBuilderConfiguration.<init>(PackageBuilderConfiguration.java:153)     at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:254)     at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:182)     at org.drools.builder.impl.KnowledgeBuilderFactoryServiceImpl.newKnowledgeBuilder(KnowledgeBuilderFactoryServiceImpl.java:34)     at org.drools.builder.KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBuilderFactory.java:46)     at com.sample.ProcessTest.readKnowledgeBase(ProcessTest.java:40)     at com.sample.ProcessTest.main(ProcessTest.java:24) Caused by: org.drools.RuntimeDroolsException: value '1.7' is not a valid language level     at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.getDefaultLanguageLevel(JavaDialectConfiguration.java:161)     at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.init(JavaDialectConfiguration.java:56)     at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:273)     ... Obviously there's more, but that's all my Console pane would show. Anyone know what's going on? What I'm possibly missing? Curious: It looks like the root of the problem is "org.drools.RuntimeDroolsException: value '1.7' is not a valid language level", but I doubt Drools would refuse to run on a newer version of the JDK. Thanks in advance for any help! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/623045#623045] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
