  ****************************************************************
  When JMS application was migrated from WAS v8 to WAS v9,
  applications connecting to JMS resource received the
  following error:
  J2CA0045E: Connection not available while invoking method
  createOrWaitForConnection for resource: jms/FH.LOCAL.QCF.
  

Problem conclusion

• The J2CA0045E error occurred because the Web services code was
  creating two service instances for the same  Web services
  provider which prevented the connection from being released to
  the connection pool.
  The problem was fixed by creating only one insntance of the
  Web services implementation class.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.5.1.  Please refer to the Recommended Updates
