Hi,

There have been a few people with Tomcat deployment issues for kie-drools-wb, so I thought I'd give it a try.

These are the steps I followed for successful deployment (most of which is already documented, but not obvious, in the WAR's README.txt file):-

6.0.1

Starting with a clean install of Tomcat 7.

1. Copy "kie-tomcat-integration" JAR into TOMCAT_HOME/lib (org.kie:kie-tomcat-integration)

2. Copy "JACC" JAR into TOMCAT_HOME/lib (javax.security.jacc:artifactId=javax.security.jacc-api in JBoss Maven Repository)

3. Copy "slf4j-api" JAR into TOMCAT_HOME/lib (org.slf4j:artifactId=slf4j-api in JBoss Maven Repository)

4. Add valve configuration into TOMCAT_HOME/conf/server.xml inside <Host> element as last valve definition:

5. Edit TOMCAT_HOME/conf/tomcat-users.xml to include roles and users, make sure there will be 'analyst' or 'admin' roles defined as it's required to be authorized to use kie-wb

6. Delete org.uberfire.security.auth.AuthenticationSource inside WEB-INF/classes/META-INF/services

7. Rename org.uberfire.security.auth.AuthenticationSource-TOMCAT-JEE-SECURITY to org.uberfire.security.auth.AuthenticationSource inside WEB-INF/classes/META-INF/services

8. Increase Java's PermGen space by adding file TOMCAT_HOME/bin/setenv.sh containing export JAVA_OPTS="-Xmx1024m -XX:MaxPermSize=256m"

9. Start Tomcat with TOMCAT_HOME/bin/startup.sh

10. Go to Management Console, http://localhost:8080/management

11. Deploy modified WAR

If you do not complete these steps the WAR works "out of the box" but you'll need to define Users in WEB-INF/classes/login.config

6.1.0-SNAPSHOT

Starting with a clean install of Tomcat 7.

1. Copy "kie-tomcat-integration" JAR into TOMCAT_HOME/lib (org.kie:kie-tomcat-integration)

2. Copy "JACC" JAR into TOMCAT_HOME/lib (javax.security.jacc:artifactId=javax.security.jacc-api in JBoss Maven Repository)

3. Copy "slf4j-api" JAR into TOMCAT_HOME/lib (org.slf4j:artifactId=slf4j-api in JBoss Maven Repository)

4. Add valve configuration into TOMCAT_HOME/conf/server.xml inside Host element as last valve definition:

5. Edit TOMCAT_HOME/conf/tomcat-users.xml to include roles and users, make sure there will be 'analyst' or 'admin' roles defined as it's required to be authorized to use kie-wb

6. Start Tomcat with TOMCAT_HOME/bin/startup.sh

7. Go to Management Console, http://localhost:8080/management

8. Deploy modified WAR

With kind regards,

Mike

Hi,
I'm trying to get set up with Drools and Guvnor. I've had some success building a test program with Drools, but when I saw that there's a webapp
to manage and view rules, I was interested in getting that working as well. Unfortunately I haven't had much success with that.
I downloaded the kie-drools-wb-distribution-6.0.1.Final.zip file from the JBoss drools website and dropped the binaries/kie-drools-wb-distribution-wars-6.0.1.Final-tomcat7.0.war
into my Tomcat directory. Tomcat was just hanging for a while, then spit out a bunch of error messages:

Next I tried building the workbench from source:
https://github.com/droolsjbpm/drools-wb/archive/6.0.1.Final.zip
The maven build worked, and I dropped the tomcat war into the tomcat directory (removing any existing webapps and wars). Starting Tomcat now produced these errors:

INFO: Deploying web application archive /opt/tomcat/tomcat7/webapps/drools-workbench-6.0.1.Final-tomcat7.0.war 2014-04-10 13:46:31,975 [localhost-startStop-1]

ERROR Failed to setup Repository 'uf-playground' java.lang.RuntimeException: https://github.com/guvnorngtestuser1/guvnorng-playground.git: cannot open git-upload-pack

What is the webapp trying to do with Git? Do I need to point it at some git repo?

I tried the jboss instructions here:

http://blog.athico.com/2013/05/how-to-build-and-run-drools-and-guvnor.html

But that didn't work either, with Jboss just hanging as well. Any clues on what might be going wrong?

Thanks,
Ven
