Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
Hello, I have similar problem while listing processes in gwt-console - 'Could not initialize stateful knowledge session'. I tried to go through manual to set up drools flow with humantasks. I basicly went through https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch14.html#d0e3588 .

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
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 and update the
persistence.xml file in the /WEB-INF/classes/META-INF/ directory? Make
sure the following classes are listed:
classorg.drools.persistence.session.SessionInfo/class
classorg.drools.persistence.processinstance.ProcessInstanceInfo/class
classorg.drools.persistence.processinstance.variabletypes.JPAPersistedVariable/class
classorg.drools.persistence.processinstance.variabletypes.VariableInstanceInfo/class
classorg.drools.persistence.processinstance.variabletypes.SerializablePersistedVariable/class
classorg.drools.persistence.processinstance.WorkItemInfo/class
Could you also specify the OS and version of the application server you
are using?
Thx,
Kris

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
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.

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
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 fix this issue.

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
hi Alok, Here are steps you might want to check. 1.) Make sure you have started a user task. As Kris suggests 'To start a task service locally: the drools-process-task module contains a org.drools.task.RunTaskService class in the src/test/java source folder that can be used to start a task server. ' 2.) Make sure you have created a sample data source (e.g testDS1-ds.xml in default\deploy) as shown in https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch14.html#d0e3553 3.) Most important one: In Guvnor, create a new package default (not the defaultpackage that comes with Guvnor) and upload a sample workflow there. Save it and build the package. From your error, it looks like you have not started the user task (Step1) Alok Patnaik wrote: Hi Satish/Krisv, I’m new to Drools. I’m stuck on the same issue.

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
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 https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch.Human_Tasks.html#d0e2117 Not sure about that second error, but let me know if that is still there if you have the task service running.

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? The NPE seems to indicate that it cannot find the knowledge base for package default on Guvnor.

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
I have built the war files using the code from SVN and following is the stack
tarce.
I also see a warning in server logs that says 'WARN [PluginMgr] Unable to
load plugin: 'org.jboss.bpm.console.server.plugin.ProcessEnginePlugin'.
Do I need to copy any jar file in JBoss's lib folder
(jboss-4.2.3.GA\server\default\lib)?
Again, here are steps I followed so far:
1.) Downloaded the Standalone Guvnor with JBoss AS.
2.) Copied gwt-console war files (gwt-console-server-drools-{version}.war
and gwt-console-drools-{version}.war) in the Standalone download
(jboss-4.2.3.GA\server\default\ldeploy)
3.) Uploaded a test rule flow in Guvnor's default package and rebuilt it.
4.) Created the data-source (that got deployed fine), did not anything for
history or reports configuration to start with.
JBoss started without any error. When I logged in, I get the following

Re: [rules-users] Drools flow web console (5.1.M1) deployment in JBoss
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.
To start a task service locally: the drools-process-task module contains
a org.drools.task.RunTaskService class in the src/test/java source
folder that can be used to start a task server.
I admit that this should be handled in a more user-friendly manner
though, I'll see what I can do.

The full stack trace of the error that should be visible in the server
console could help to identify the issue as well.

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

I downloaded the âStandalone Guvnor with JBoss ASâ (Drools
5.1.0.M1 Guvnor
Standalone) from the download site.
As it did not have the gwt-console war files
(gwt-console-server-drools-{version}.war and
gwt-console-drools-{version}.war) in the Standalone download, I built
them
from source code and deployed in JBoss.
I uploaded a test rule flow in Guvnorâs default package and rebuilt
the
package.
After log into gwt-console, when I click on process definition, I
see a

Damn, the DroolsFlowCommandDelegate seems to be swallowing the exception, as the exception caught there is not added as the root of the thrown exception (line 68). There's no stack trace of a NullPointerException in the log (right) before this error? I also fixed this on trunk, so the caught NullPointerException is added as the root cause now, so the stack trace should now contain the trace of the NPE as well. If there's no NPE in the log, could you update your code from SVN, rebuild the wars, try again and send me the stack trace again? Kris Quoting satjo jo_sat...@yahoo.com: I have set the data source.

Could some one share the experience in getting the Drools Flow 5.1 web
console working in JBoss?
I downloaded the “Standalone Guvnor with JBoss AS” (Drools 5.1.0.M1 Guvnor
Standalone) from the download site.
As it did not have the gwt-console war files
(gwt-console-server-drools-{version}.war and

from source code and deployed in JBoss.
I uploaded a test rule flow in Guvnor’s default package and rebuilt the
package.
After log into gwt-console, when I click on process definition, I see a
HTTP 500 error ‘class com.google.gwt.http.client.RequestException', ‘ Could
not initialize stateful knowledge session: null’.
Any comments on the required steps for viewing the process definitions are
appreciated.
