hi sachin,
thanx for ur reply
i changed that made  the home reference as a clas variable but then too  it was giving this exception
but when i went through the code carefully
i saw that instead of writing weblogic.jndi.WLInitialContextFactory i had missed out c in weblogic
any way thanxbut i was wonderig how it got compiled
thanx any way
