hi ,
I am using 3 tier architecture where my
servlets and htmls are placed in the iplanet webserver4.1 and my
EJB in
are in weblogic server 4.5.1 and the Weblogic server uses oci driver to connect to oracle 8.1.6 .
when I am trying to access the EJB which is deployed in weblogic4.5.1 from servlets which are on iplanet webserver 4.1
.I am facing a problem where the servlet in iplanet is not able able to lookup the bean which are deployed on weblogic server using their JNDI lookup name .I am using t3 connectivity to comunicate with the EJB from the servlets.My request hangs for a long time and then displays a insecure item dialog box in the browser.when i checked up the weblogic logs i found no exception or errors while the iplanet log showed me this error [Root exception is java.net.ConnectException: Connection refused]javax.naming.CommunicationException
.The servlet is unable to lookup the bean and I found the connectivity between the iplanet webserver machine and the weblogic server machine is lost and i was not able to invoke a telnet session from iplanet webserver machine to weblogic server machine it is giving connection refused.however if i shut and start iplanet webserver the connectivity is restablished and i am able to invoked the bean from the servlets.This problem is happening once in a while but still i am not able to find a permanent solution for it can anybody give the reason why this is happening the only solution that i have now is to restart iplanet webserver.
I suspect it is due to ports getting locked any one help me
please
thanks for your ideas in advance
