WebSphere javax.naming.NamingException and connection refused

I have deployed a secure ejb on machine1, when I run the client code on the same machine, it works fine. But when I run the client code on any other machine it throws an error. which is pasted below.

In the error it can be seen that its not taking the ip: that is provided but instead it looks in the client machine itself. Where is the problem is it in the client code or am I missing some settings in WebSphere.

Update

Port Details

I have created the node and profile using the following script:

File1:setUpEnv.bat

set WAS_HOME=C:\IBM\WebSphere\AppServer
set HOST_NAME=localhost
set PROFILE_NAME=AppSrv01

set NODE_NAME=%PROFILE_NAME%Node01
set CELL_NAME=%NODE_NAME%Cell  
set SERVER_NAME=server1

set DMGR_USER=user1
set DMGR_PASSWORD=123456
set DMGR_HOST=localhost
set DMGR_PORT=8879

File2:

CALL ./setUpEnv.bat
set WAS_HOME=C:\IBM\WebSphere\AppServer
CALL %WAS_HOME%\bin\manageprofiles.bat -create -profileName %PROFILE_NAME% -       profilePath %WAS_HOME%\profiles\%PROFILE_NAME% -templatePath %WAS_HOME%\profileTemplates\default -serverName %SERVER_NAME% -cellName %CELL_NAME% -nodeName %NODE_NAME% -hostName %HOST_NAME% -enableAdminSecurity true -adminUserName %DMGR_USER% -adminPassword %DMGR_PASSWORD%
Solution

  • The 9403 is correct port for RMI/IIOP SSL communication (CSIV2_ SSL_ SERVERAUTH_ LISTENER_ ADDRESS). It might happen that you incorrectly installed WAS using localhost, and it sends to the client redirection for the localhost instead for its host name.

    Double check WAS configuration for example via web console, in the Server -> Administration -> ports section.

    If you installed WAS using localhost, you will either have to change host, or recreate provile (the second might be easier if you are a new to WAS).
