Jbpm-console seam to be a very good starting point if we need to write an application that
allow user to deploy is own defined processes.
In order to package the jbpm-console with additional feature specific to our customers, I
plan to benefit for the ease of development that seam allows. I have written some small
seam application. Then, I try to integrate the seam jar and required configuration in
web.xml, faces-config.xml seam.properties...
Since then, the jbpm-console seems to work fine (I am able to initiated process, complete
task ...). However, I keep getting the stack trace, which will follow, for almost every
action I perform in the jbpm-console. Do you have an idea how to fix this?
The stack trace is something I have tried to fix. However, since the application seems to
work fine, I have tried to use backing bean. I still have some problem (probably due to my
short experience with seam) but I have been able to use the websale demo and add a call to
a backing bean in the form.create.xhtml file. For now I have add to put my backing bean
directly into the WEB-INF/classes/âÃÂæ folder. Does anybody have tried to have the
seam backing been versioned in the par file like the action handler and forms are?
thanks in advance for you precious help,
An Phong Do
I have added the stack trace add content of configuration files here.
