Re: [rules-users] Problems deploying war

I'm not quite sure why it's so challenging to get the war deployed with Tomcat. Is it easier to deploy the war with Jboss?
These are the exceptions I'm getting, even after adding "-Dorg.kie.demo=false" to the CATALINA_OPTS in catalina.sh
I want to disable the access to remote git repos.

If apply the additional configuration you are telling Tomcat to use Users defined in <tomcat_install_folder>/conf/tomcat-users.xml

I modified the WAR by unzipping it, modifying the relevant files and then zipping it back into a WAR before deploying.

Hi Michael,
Unfortunately I can't seem to get the 6.0.1 version up and running. I followed the steps below, finding the 3 jars listed below online.
But still, Tomcat just hangs for a bit, then throws a bunch of severe warnings. There don't seem to be any log messages describing the problem.
Also, I'm a bit confused by the directions - how can we modify the WEB-INF directory before the war is deployed? And how do we define users
in the login.config file?

Thanks,
Ven

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:

<Valve className="org.kie.integration.tomcat.JACCValve" />

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:

<Valve className="org.kie.integration.tomcat.JACCValve" />

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
