    Hi Pradeep,

    This seems to be missing Jar file. There is one portion in Williams blog itself.

    Putting it for your reference and if required you can take help from your basis team.

    In order to develop the user-module locally on the NW Developer Studio on your laptop, some PI libraries will be required. These libraries must be included in the java classpath during development.

    The libraries, or jar files, have to be taken from an existing SAP PI installation. Find the library files in following folders: <bin>/services/ <bin>/ext/\lib <bin>/interfaces/ <bin>/services/ /system
