[rules-users] RuntimeDroolsException

[Kris Verlaenen]

This exception is thrown when it cannot find (one of) the necessary libraries for loading the Java Dialect.  In this case probably the eclipse jdt compiler.  Make sure all the necessary dependencies are in your classpath.  If you are using a Drools project, the Drools classpath container should automatically do that for you.

However, note that the eclipse plugin currently only works with eclipse 3.2.x, it will be upgraded to 3.3 for the next major release.  If I remember correctly, I believe this exception is thrown if you try to use the plugin in eclipse 3.3.

  Hi,

  I'm starting to use eclipse plug.in for JRules. I created the example JRules project in eclipse and I tried to start it as Java Application but I got this exception

  org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialect:java'
      at org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry (PackageBuilderConfiguration.java:156)
      at org.drools.compiler.PackageBuilder.<init>( PackageBuilder.java:131)
      at org.drools.compiler.PackageBuilder .<init>(PackageBuilder.java:84)
      at com.sample.DroolsTest.readRule(DroolsTest.java:50) 
      at com.sample.DroolsTest.main(DroolsTest.java:21)

  Can someone help me?
  Thanks
  Raffo
