<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So far so good.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In Eclipse, I tried to debug the first sample app: evaluation | ProcessTest.java. I got this error:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java:org.drools.rule.builder.dialect.java.JavaDialectConfiguration'</p><p>    at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:277)</p><p>    at org.drools.compiler.PackageBuilderConfiguration.buildDialectConfigurationMap(PackageBuilderConfiguration.java:262)</p><p>    at org.drools.compiler.PackageBuilderConfiguration.init(PackageBuilderConfiguration.java:175)</p><p>    at org.drools.compiler.PackageBuilderConfiguration.<init>(PackageBuilderConfiguration.java:153)</p><p>    at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:254)</p><p>    at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:182)</p><p>    at org.drools.builder.impl.KnowledgeBuilderFactoryServiceImpl.newKnowledgeBuilder(KnowledgeBuilderFactoryServiceImpl.java:34)</p><p>    at org.drools.builder.KnowledgeBuilderFactory.newKnowledgeBuilder(KnowledgeBuilderFactory.java:46)</p><p>    at com.sample.ProcessTest.readKnowledgeBase(ProcessTest.java:40)</p><p>    at com.sample.ProcessTest.main(ProcessTest.java:24)</p><p>Caused by: org.drools.RuntimeDroolsException: value '1.7' is not a valid language level</p><p>    at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.getDefaultLanguageLevel(JavaDialectConfiguration.java:161)</p><p>    at org.drools.rule.builder.dialect.java.JavaDialectConfiguration.init(JavaDialectConfiguration.java:56)</p><p>    at org.drools.compiler.PackageBuilderConfiguration.addDialect(PackageBuilderConfiguration.java:273)</p><p>    ...</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Obviously there's more, but that's all my Console pane would show.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Anyone know what's going on? What I'm possibly missing?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>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.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks in advance for any help!</p></div>
