Null Pointer Exception when Executing SAP Service

  • 1.  Null Pointer Exception when Executing SAP Service

    Posted Mon December 23, 2002 06:59 AM

    Hi,

    I am using IS4.6, RN4.6 and connection to SAP.

    I have a conversation that receives 3A4, executes a RFC service which creates the order in SAP.

    The conversation is working fine but occasionally, I will get a Null Pointer Exception ,especially after a period of inactivity.

    Did anyone face the same problem?

    I am attaching the error message below:
