Update::: On the exception(mentioned below) related to jar “drools-bpmn2-5.1.0.M2.jar”, I recreated this jar file from the Drools source (5.1.0.M2) against JDK6  and the exception went away. J So far so good.

Plugin related exception is still there. I replaced the jar “drools-bpmn2.jar” which is present in the lib of plugin jar “org.drools.eclipse_5.1.0.M2.jar” with the recompiled jar, but not much luck – plugin is still not able to open the “*.bpmn” process. The error I get is “The method getTextContent() is undefined for the type Node” .

Right now I am at a dead end. Thanks in advance for help.

Thanks

Vijay

I created a sample project to run a very simple rule flow (BPMN process), I got the similar error which the plugin is reporting. My env is SUN JDK 6. Here is the exception I get?  Any clue guys.

Subject: Drools 5.1.0.M2 - BPMN2 process issue - Eclipse plugin. -- The method getTextContent() is undefined for the type Node

Hi,

I just downloaded the Drools 5.1.0.M2 (have been using the snapshot version of around 16^th April 2010) – created a sample “rule flow file(startàuser taskàend) – bpmn2 version”. But when I clicked the file to open it gave the following error (image attached)

“The method getTextContent() is undefined for the type Node” .

I understand this error is related to org.w3c.dom.Node where this method was added as part of DOM Level 3 and available in JDK 5+ . My project and eclipse is configured against JDK 6+ . Not sure why this error with M2.

May be it is because of the drools-bpmn2.jar included in the drools eclipse plugin? Can someone shed some light that where it might be going wrong.

Thanks

Vijay
