[rules-users] errors with GWT-console

Guvnor was changed recently to add authentication when downloading packages.  The console was not yet updated for this in 5.1.0.M1, so you'll need to update to the latest trunk.  Luckily, there's now also an installation script that should simplify things as well.

Take a look at http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/install/readme.txt

  Subject: [rules-users] errors with GWT-console


  I am a new to Drools Flow, guvnor, and GWT-console-server-drools.

  I am trying to deploy Gwt-console-server and to get a process running in it. 

  I am using Drools 5.1.0.M1, JBoss-AS 4.2.3.GA. 

  I have followed all the instruction in the Drools Flow 5.1.0 Documentation, the chapter about Console. 
  When I start the aplication server I get the following errors: 

  10:31:16,957 INFO  [TomcatDeployer] deploy, ctxPath=/gwt-console-server, warUrl=
