Hi ,
I have created a simple bpmn job using jbpm 5.4 libraries "start ---> task -> and \
end event". I have attached a custom work item handler to the task ( \
CustomHandler.java) . I have been able to successfully commit the bpm file into \
guvnor and compile the package. The Jar file is copied into \
\jboss-as-7.1.1.Final\standalone\deployments\jbpm-gwt-console-server.war\WEB-INF\lib\ \
folder.
When I open the jbpm console ( http://localhost:8080/jbpm-console/ \
http://localhost:8080/jbpm-console/ ) i can see the process listed , but when I try \
to click start the process it errors out with the following msg :
server/rs/process/definition/com.sample.bpmn.sampleHTformvariables/new_instance
2013-07-31 16:23:37,610 [ERROR] <ul><li>URL: ' \
http://localhost:8080/gwt-console-server/rs/process/definition/com.sample.bpmn.sampleHTformvariables/new_instance \
http://localhost:8080/gwt-console-server/rs/process/definition/com.sample.bpmn.sampleHTformvariables/new_instance'
<li>Action: 'org.jboss.bpm.console.client.process.StartNewInstanceAction'
<li>Exception: 'class com.google.gwt.http.client.RequestException'</ul>
HTTP 500: Unknown error
com.google.gwt.http.client.RequestException:
HTTP 500: Unknown error
When I replace the Task with a User Task , the process starts without any issues.
I would appreciate some assistance on this , have been dealing with this issue for \
the past few days !
Thanks in advance
Senthil
