We are working on SAP NW 7.0 connectivity to an external J2EE application running on Websphere platform using RMI protocol. We are facing issues in connecting a Java application running on NW 7.0 to that external application.
The EJB of the external system is running on Web sphere and Java application on NW server is acting as ejb client. Web sphere is running on IBM JDK and NW is running on HP JDK.
The application and connection works fine for some time and after some time the integration stops working and all further new requests do not go through. We found that the initial context look up stops working after some time. The JNDI Look up is the line where it gets stuck. Once we restart NW service again, things start working and stops again after some time.
We are unable to identify the root cause of the issue.
Thanks in advance.
