Grails

Cannot deploy multiple apps with different databases with shared lib folder

Details

  • Type: Bug Bug
  • Status: Open Open
  • Priority: Major Major
  • Resolution: Unresolved
  • Affects Version/s: 1.1.1
  • Fix Version/s: None
  • Component/s: Persistence
  • Labels:
    None
  • Environment:
    Jboss 4.02 running on SUSE

Description

If you run more than one app on the same server, where each app is compiled with the "nojars" option, and all the libs are shared in the container's lib folder (jboss lib folder in my case), both apps end up pointing at the same database (the one deployed first)

If you create a normal war file with all jars, but remove all but the grails-*.jar files, everything is fine.

Hi i too facing the same issue when multiple wars are deployed on liferay. I followed your solution keeping only grails-*.jar files in war and rest of jars in tomcat/shared/lib .

But still i was getting issues like this :

SEVERE: StandardWrapper.Throwable
java.lang.LinkageError: loader constraint violation: when resolving field "logger" the class loader (instance of org/apache/catalina/loader/WebappClassLoader) of the referring class, org/springframework/web/servlet/HttpServletBean, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for the field's resolved type, org/apache/commons/logging/Log, have different Class objects for that type

Any updates on this issue? This also occurs with Glassfish Webapplication server. I spent few nightmarish days trying to work it out and gave up.
