Comment: WebLogic 12c conflict with Bouncy Castle library

WebLogic 10 conflict with commons-lang library

When deploying on Weblogic 10, there is a version conflict while using commons-lang. While Weblogic-10 is distributed with commons-lang-2.3.jar, JackRabbit and Magnolia CMS need at least commons-lang-2.4.jar. To resolve this issue, modify setDomainEnv.sh of Weblogic and add commons-lang-2.4.jar to the PRE_CLASSPATH. Since version 2.4 commons-lang doesn't remove any methods, but only adds new API and fixes known bugs, there is no adverse effect from this change to the Weblogic installation.

WebLogic 12c conflict with Bouncy Castle library

Magnolia uses the Bouncy Castle cryptography package to decode the license key and to secure the activation process. WebLogic 12c is distributed with bcprov-jdk16-1.45.jar but Magnolia is distributed with bcprov-jdk16-1.46.jar. This leads to a library version conflict.

Symptom: There is no error shown on the Magnolia license form but the license is not registered. In the log you can find this stack trace:

To resolve:

  1. Edit setDomainEnv.sh in WebLogic and add bcprov-jdk16-1.46.jar to PRE_CLASSPATH.
  2. Remove bcprov-jdk16-1.45.jar from WebLogic 12c common libraries.

Mac OS X 10.5 - Leopard

If you use Mac OS X 10.5 or 10.6, you should update to at least 10.5.8 or 10.6.2. Earlier versions cause issues where, when two or more instances are started in the same container, some or all connections are dropped.
