Hi Gurus,

I have to develop a customsed java module for reading Excel files from PI. I downloaded NWDS 7.31 from following location NWDS Download links - Java Development - SCN Wiki. I have installed it on my local laptop. For developing the module I need following Jar files.

1. com.sap.aii.af.ms.svc_api
2. com.sap.aii.proxy.svc_api.jar
3. com.sap.aii.sec.svc_api.jar
4. com.sap.aii.utilxi.server.jar
5. com.sap.aii.utilxi.core.jar
6. com.sap.xi.mapping.tool.lib_api.jar
7. sap.com~tc~bl~txmanagerimpl~plb~impl.jar
8. sap.com~tc~je~appcontect_api~API.jar
9. com.sap.aii.af.cpa.svc.api
10. com.sap.aii.af.lib.mod
11. com.sap.aii.af.ms.ifc_api
12. com.sap.aii.af.svc_api
13. com.sap.xpi.ib.mapping.lib

Thanks in advance
