OK, I found how to overcome it.
You can apply patch for better session object creation (from attachment).

I realized this issue Yesterday that the persistence.xml file inside
gwt-console-server-drools-*.war under the path /WEB-INF/classes/META-INF
dont contain the list u have mentioned.
what I did is that I added the list to the persistence.xml file and
restarted the server and I have the following
As mentioned before, the exception you are seeing is caused by the fact
that JPA cannot find the definition of the ProcessInstanceInfo element
when trying to persist it. These elements are referenced in the
persistence.xml configuration files.
Could you check your gwt-console-server-drools-*.war
Please check the java code and the process that I am uploading:
1- Java code:
package com.fp;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
Yes as Mauricio stated that the persistence.xml inside the persistence-jpa
contains the classes needed
1- Should I have another persistence.xml than that found inside the
persistence-jpa.jar
2- Should the jar file uploaded inside the Guvonor contains a
persistence.xml

What I am trying to do is to upload a rule file process that is simply a user
task that sends an email
here is the steps that I have made:
1- I upload the jar file into the Guvonr
2- I upload the rule flow file also into Guvonr
3- I built the backage and restarted the JBOSS server
4- I started
Can you post here your code? or what are you trying to achieve?

Thank you kris,
Removing persistance-api.jar from the gwt-console-server-drools.war helped
to remove the error. Now I'm able to view the process on web-console.
However, when I'm clicking on Start under Process Instances, the following
error occurs. Can you please suggest how can I solve this. I'
I'm guessing that you have multiple version of javax.persistence in your
classpath (one in the server war and one on the server classpath),
causing the cast to fail. Could you verify that this might be true?
If so, simply remove the duplicate persistence-api.jar from the server
war, that should f
Thank you for the reply Kris and Satish. It really helped me to remove the
errors from eclipse. However I still face the error when I click on process

I just build from trunk usually, but the M1 version should be fine.
The error "Could not connect to task client" is probably caused by the
fact that you did not set up a task service (you need one if you want to
use human tasks)? Check out

hi Alok,
Here are steps you might want to check.
1.) Make sure you have started a user task.

folder that can be used to start a task se
Hi Satish/Krisv,
I’m new to Drools. I’m stuck on the same issue.
Although I did every step you have mentioned. My jboss still starts with

You pointed out the exact issue. This was what happened. I was using
defaultpackage of Guvnor, thinking it refers to the "default".
After I created the new package called "default" and uploaded the
definition, it worked fine and it did not throw any exception.

When you uploaded your sample process to Guvnor, did you add it to the
"default" package (notice that the name should really be "default", and
not "defaultPackage", which is created in Guvnor by default)? And after
adding the process to the package, did you build the package on Guvnor?

Thanks for your response!
It did fix the problem and I do not get the exception after I log in if I
run org.drools.task.RunTaskService.
I, however, get exception if I click on 'Process Definitions'->'Definition

This exception is simply caused by the fact that you don't have a human
task service installed. So when the console tries to show the tasks of
the user, or execute a process, it will fail to connect.

Could some one share the experience in getting the Drools Flow 5.1 web

I downloaded the “Standalone Guvnor with JBoss AS” (Drools 5.1.0.M1 Guvnor
Standalone) from the download site.
