  Goal: Launching Interstage BPM Server Fails to Start in RedHat JBoss Enterprise Application Platform Version 5

  
  

  Fact: Interstage BPM Version 11.2

  
  

  Fact: Interstage BPM Version 11.2a

  
  

  Fact: RedHat JBoss EAP (Enterprise Application Platform) Version 5

  
  

  Fact: Windows

  
  

  Fact: RedHat Linux Version 5

  
  

  Symptom: 

  Starting up Interstage BPM server fails due to the error:

  WARN  [org.jboss.detailed.classloader.ClassLoaderManager] (main) Unexpected error during load ofrg.jboss.resource.metadata.repository.DefaultJCAMetaDataRepository

  java.lang.UnsupportedClassVersionError: Bad version number in .class file

  
  

  Fix:

  The problem is caused by the JDK version used to launch Interstage BPM server.  In this particular case, JDK used is v1.5, while RedHat JBoss EAP Version 5 supports mininum JDK 1.6 and BPM engine requires minimum JDK v1.6 update 20.  See the excerpt below from REdHat JBoss EAP 5 datasheet (http://www.redhat.com/f/pdf/jb_ent_app_platform_04_07.pdf ):

  
  

  platform and standards support

  JBoss enterprise application platform 5

  minimum system requirements

  • JDK 1.6 

  • 512 MB RAM

  • 100 MB hard disk space

  • 400 MHz CPU

  supported JdKs

  • Sun JDK 1.6

  • OpenJDK 1.6

  • IBM JDK 1.6

  
  

  To rectify the issue, make sure JDK used is the supported JDK 1.6 update 20, as mentioned in BPM engine release note.

   

  In Windows, locate and edit {JBoss home}binsetEnv.cmd by adding the following entry:

  SET JAVA_HOME=<path to 1.6.0_20 JDK home directory>

  Example:

  SET JAVA_HOME=c:jdk1.6.0_20

  
  

  In Linux, locate and edit {JBoss home}/bin/setEnv.sh by adding the following entry:

  JAVA_HOME=<path to 1.6.0_20 JDK home directory>

  export JAVA_HOME

  
  

  Note: Alternatively, it is also possible to add the environment variable JAVA_HOME=<path to 1.6.0_20 JDK home directory> in run.conf instead of setEnv.sh.
