Hi,
Any one tried with Sevlet and EJB component on different machines??
I have tried with Weblogic 4.5 and NAS4.0 - Both cases the servlet is unable to
connect to the remote bean through look up services.
Is there any special setting required for this apart from setting the provider_url to
the proper IP address.
I am using something like t3://192.123.1.1:7001 for Web logic and
Regards,
Sripa
