ORA-29540 Java Class does not exist

 Hello,We have 2-nodes 11gR2 RAC/Win2k8. I've created a Java class/stored procedure after I connected to the DB using the below  TNS entry 

orcl =

  (DESCRIPTION =

    (LOAD_BALANCE = yes)

    (ADDRESS = (PROTOCOL = TCP)(HOST = node1.domain)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = node2.domain)(PORT = 1521))

    (CONNECT_DATA =

      (SERVICE_NAME = orcl)

      (FAILOVER_MODE =

        (TYPE = SELECT)

        (METHOD = BASIC)

        (RETRIES = 60)

        (DELAY = 3)

      )

    )

  )

I've noticed that this java class is available from one instance but unavailable from the other (ORA-29540 Java Class does not exist)

However, If I connect to the DB using the below TNS, the java class is available from both instances.
