Is there anything i am missing or is there a specific way in which custom modules have to be deployed on PI 7.31?

The issue was we were trying to deploy a jar file . When we did EAR deployment , it worked .

Also one more thing we noted was in NWDS 7.3, we have a library called the XPI library ( for mapping/module developments specifically ), when we added this and removed the earlier references, most of the warnings were gone.

Hello Anand,

Where exactly you are getting this error? and how u are deploying your module using NWDS or JSPM?

Thanks

Hi Amit,

The BASIS team is deploying it using "deploy" command on the server.

Is there any specific way in which module has to be deployed in PI 7.31 support.

I have heard JSPM is not supported in PI7.31 for deplyoment.

Please call me once.

Rgds,

Anand
