kie workbench deploy war not working (tomcat)

Question

I have downloaded the kie workbench and extracted kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7.war. I've never used tomcat before, but I wanted to use the workbench and there didn't appear to be an option for the workbench to simply spin itself up. Consequently, I installed tomcat 8. After doing this I accessed the tomcat manager and deployed the war. (I had to increase the memory limit on acceptable file sizes)

I now have /kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7 listed as an application, but it won't start. When I try to start it I get the following:

FAIL - Application at context path /kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7 could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7]]

This is the catalina log file:

I looks like there is some sort of parse error in context.xml. However, since this is an unmodified of code downloaded directly from drools, I don't understand what could be wrong with it.

Answer 1

After your .war file gets exploded by tomcat you wil need to cd into /kie-drools-wb-distribution-wars-6.2.0.Final-tomcat7 directory. There is a README.txt file in there which provides further installation notes:

1. Install bitronix transaction manager into your tomcat

2. Create configuration files inside TOMCAT_HOME/conf

   • btm-config.properties

3. Define system properties for btm.root, bitronix config file, JBoss logging provider and others.

4. Configure JEE security for kie-wb on tomcat (with default realm backed by tomcat-users.xml)

(list elements were copy pasted from README.txt) Follow the instructions in there and it should work. I think the error you are getting is related with step 1 and bitronix transaction manager.

hope that helps

Answer 2

I did a quick fix that solved this:

1. Remove kie-server WAR file from tomcat webapps directory, so that it won't undo the next step.
2. Delete the problem file webapps/kie-server-6.3.0.CR2-ee7/WEB-INF/lib/slf4j-api-1.7.2.jar

I did also the following which might be needed:

3. I replaced latest slf4j jar files from /opt/apache-tomcat-8.0.26/lib directory with version 1.7.2 files. Perhaps Drools trusts in that it should work with latest version as well since they don't ship the files needed for deployment with the WAR files, but ask everyone to fetch latest files. So this step might not be necessary.
