the result returned stored procedure contains object of oracle.sql.array (object referring ojdbc jar of jboss module)

and tried converting oracle.sql.array throwing exception

code:

url resultjarlocation= resultmap.get("returnobj").getclass().getprotectiondomain().getcodesource().getlocation(); url appjarlocation = oracle.sql.array.class.getprotectiondomain().getcodesource().getlocation(); system.out.println("resultjarlocation : " + resultjarlocation); system.out.println("appjarlocation : " + appjarlocation); oracle.sql.array returnobj=(oracle.sql.array)resultmap.get("returnobj");

exception:

you trying cast between classes loaded different classloaders. jvm distinguishes classes not name , bundle classloader used. in other words, jvm perspective trying cast string long; cannot. think can configuration. set either same classloader used, or classloaders in same hierarchy, take advantage of delegation.

i not familiar jboss (especially current versions) know has (or used have in past) different classloading strategy other application servers. checking documentation on classloading first option.
