I have just finished installing it and am able to lauch Eclipse plugin UI. I have imported a couple of example projects to test and play around with. When I try to execute the process with 'run as java application' I get the following 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)     ... 9 more Can anyone shed any light as to how this can be resolved? Am I missing plugins or Drools Rule Engine? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632929#632929] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
