Update::: Issues related to Plugin. When I recompiled the bpmn2 src and put that jar in the plugin lib, it simply didn't took the recompiled version. Then I removed the jar from the plugin lib and simply copied the - bpmn2 classes directly in the org/drools package of the plugin and voila - plugin started working fine.

Thanks
Vijay

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. :) 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

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 16th April 2010) - created a sample "rule flow file(start-->user task-->end) - 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.
