KIE-Workbench + Tomcat + LDAP Authentication

[durani163]

Hi Guys,

I have been working with JBPM6.1.0 with Tomcat7 & Oracle databasee. I am using KIE Workbench–Tomcat7. I could successfully configure it and could start the kie-workbench using the users & roles provided in the tomcat-users.xml file of a Tomcat server. I want to use LDAP authentication for KIE workbench which actually running on Tomcat server.

I could find out the posts related to JBoss server + LDAP setup and could not find anything related to KIE-WB + Tomcat7 + LDAP. It would be very helpful If you could help me out in configuration stuff.............

Thanks In Advance,
Feroze

you need to upgrade to 6.2.0.Final for that to work smoothly. Here you can find complete installation instructions about jBPM (kie-wb) on tomcat. Then simply follow Tomcat User Guide on how to configure LDAP and you are done.

Thank you Maciej for the information.

I could successfully install kie-wb-6.2.0 on tomcat7. But I came across the below queries while playing with Evaluation example in KIE-Workbench.

1. Could not RE-deploy the project

     I could see from release notes of JBPM6.2, the property -Dorg.kie.override.deploy.enabled is defaulted to false. (in the post: Accelerate your business: marzec 2015)

• in 6.1 redeploy of same version (regardless if that was concrete version or snapshot) was by default allowed, in 6.2 concrete versions must be explicitly undeployed before they can be redeployed. This can be overridden by system property which will allow redeploy for all versions: -Dorg.kie.override.deploy.enabled=true

     Due to the above reason, I couldn't redeploy the project after the changes. Could you please let me know where can I change this configuration in kie-wb-6.2.0-Final-tomcat7.war

2. Facing below Warning on server start up. Though, I could login to Kie-wb but could not make JTA transactions.

you need to set this in setenv.sh file in tomcat_home/bin folder - it's regular JVM parameter

this indicates you don't have transaction synchronization registry in place. Make sure you define another system/jvm property in setenv.sh:

-Djbpm.tsr.jndi.lookup=java:comp/env/TransactionSynchronizationRegistry

once you have that defined it should all work well
