JBPM GWT Consolte not loading

[amit.kayal]

Hi All,

I have installed the JBPM 6.0.1 and it seems that JBPM GWT Consolte url not loading and throwing following error in the url http://localhost:8080/drools-guvnor

type Status report

message /drools-guvnor

description The requested resource (/drools-guvnor) is not available.

But my JBPM Console is working fine and the url http://localhost:8080/jbpm-console is opening the log in page

I have reinstalled multiple times and still the GWT console not working for me. Could you please help me on this?

Thanks

Amit

Hi Amit, why do you want to access to http://localhost:8080/drools-guvnor.

This is for the old guvnor of old drools versions

I think everything should be in http://localhost:8080/jbpm-console.

Thanks,

Demian

Hi Demian,

Thanks a lot for your reply. I am quite new to jBPM and was reading the book "jBPM5 Developers Guide". The book has reference of Guvnor for GWT and for all the Business Process Diagram...So are you saying that I do not need to use Guvnor/Drools console any more and will get everything into jBPM console?

Thanks

Amit
