[rules-users] GWT Console - Drools Flow problems.

Tom,

The first error is simply because you don't have a human task server running (so it can't find any human tasks).  Some info on starting the human task service can be found here:
http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch.Human_Tasks.html#d4e1215

Have you maybe tried the installer? That should allow you to setup an environment (including eclipse, human task service, guvnor and gwt-console).  Check the readme inside for more details how to:
http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/drools-5.1.0.SNAPSHOT-install.zip

The second is probably related to the same issue.

Regarding the missing ProcessEnginePlugin, you can ignore that, that is normal.

Kris

  Subject: [rules-users] GWT Console - Drools Flow problems.


    Hello,
    I am trying to use Drools Flow with GWT Console v.2.1. I use Guvnor and Eclipse too. I am new in server applications, and jBoss is for me something new, so please be patient :)
    What I did are: 

  1.)Creating processes in Eclipse. They work.
  2.)Exporting them to Guvnor - I can see them, everything is OK.

  Then I try to start GWT-Console. When I log in, I get this:

  I don't know what to do. I read similar thread to this one, but with no results for me...
  Ramran wrote there:

     "The gwt-server-console.jar contains 2 javaassit jar files. I have deleted both these jars and used only 1 javassist.jar file in the JBOSS lib folder. Try it "

  But I was looking for javaassit.jar in gwt-server-console.jar, but I don't have gwt-server-console.jar file in my jBoss... I have only "gwt-console-server-
  integration-2.1.jar".

  I want to show you my jBoss logs while starting this server:
