Get InitialContext for P4-connection via Http tunneling

Hi,

I have to use an Http tunnel to access my integration J2EE engine.

Now, I want to create a P4-connection. It doesn't work. No InitialContext will be returned.

I can open the VisualAdmin on the http tunneling port. But in the connection GUI I can select 'Http tunneling' as connection type. Is there any setting, i.e. property, for the InitialContext to signal that Http tunneling should be used ?

Regards,

Astrid
