java - How to check jndi bind/unbind status? -

-

i'm looking way of checking bind status of object , appropriate jndi name.

for example, i've got ldap jms queue name: "/therootcontext/somesubcontext/some.queue.name:queue"

i need check appropriate queue exists , binded passed name.

what correct way check "bind status"?

i see such algorithm:

  1. perform jndi lookup ensure provided name exists.

    object obj = ctx.lookup("/therootcontext/somesubcontext/some.queue.name:queue");

  2. %i don't know next%, suggest checking that:

    obj != null && obj instanceof javax.jms.queue

am correct? correct way?

most if object not found lookup throw namingexception in 1. need either catch exception or try use list method check if object exists.
