Thanks Kamal, for the reply. While invoking the session bean from MDB, had you done any special configuration settings in the xml files(like run-as in ejb-jar.xml or changes to login-config.xml file)?
Even i was able to access the session beans from MDB(WITHOUT any changes to login-config.xml or specifying run-as in ejb-jar.xml). But since a few days back i am facing this problem.
After going through some threads on this forum, i found some tips like changing the login-config.xml and ejb-jar.xml. My ORIGINAL login-config.xml was as below:
<?xml version='1.0'?>

After doing this and adding the run-as entry in ejb-jar.xml, i WAS able to invoke the session bean from the MDB. But, i still dont understand, why was i able to invoke the bean, earlier without these settings.
I also found a small comment in the login-config.xml file(in BOLD):

Does this indicate that there is some mismatch in the security-domain being used for the MDBs and the application policies defined in login-config.xml, because of which the "other" login configuration is being used, instead of the "jbossmq" login configuration(Please see that "jbossmq" login configuration has <module-option name = "unauthenticatedIdentity">guest</module-option> set by DEFAULT, because of which may be i was able to invoke the bean earlier).
If yes, how might this mismatch have occured.
Please let me know, if anyone has any answers.
Thank you.
