Description ajkrank70 2012-05-31 18:20:53 UTC
I'm trying to do a JNDI lookup inside the "onOpen" method of my StreamInbound class, but it gives me the exception below.  The code works if I move my JNP JARs to the server lib instead of the webapp lib.  The code also works fine from anywhere else, like in the "doGet" method.

I suspect we need to set the TCCL correctly for web socket calls.

Fixed in trunk and 7.0.x and will be included in 7.0.28 onwards.
