Could not get IOR from Domino server

Hello. I have a servlet in Tomcat that creates a DominoSession.

Two clustered Domino servers…both run Tomcat. Each Tomcat server contains the same servlet except the servlet is pointed via http to it’s own respective Domino server/database.

One servlet is running ok, the other servlet is throwing:

NotesException: Could not get IOR from Domino Server: java.net.ConnectException: Connection refused

I have checked…

  1. diiop is running and enabled in both clustered server documents (under the DIIOP tab in Ports)

  2. the port 63148 is specified in both servlet config files in Tomcat and matches the tcp/ip port number under the DIIOP tab in both clustered server documents

  3. Authentication options under the DIIOP tab have Yes set for both Name & password and Anonymous.

In fact, the server documents for the two clustered servers are identical for the port stuff, except for the net address. I have pretty much exhausted all my alternatives. It is really strange since these are clustered. Does anybody have any ideas? Thank you very much.

Subject: interesting…

if i try to access diiop_ior.txt via browser url for either server, i get a discrepancy…

http://cluster_server_1.here.com:63148/diiop_ior.txt (opens file)

http://cluster_server_2.here.com:63148/diiop_ior.txt (dns error)

so could something be amiss with port 63148 on cluster_server_2? thank you again.
