I will explain my problem.
I am developing a portal standalone application.There I have to read one Excel file.
So I used 'jxl-2.6.jar' which was not available in the server.
I have created one external library project and uploaded respective jar to server.
I have checked the same in visual admin as per blog "http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/2361"
and it was fine.
Now my problem is if I build my project, it is showing the error in import statement.
I have tried these all
1) added that jar as used DC
2) added the library project as project reference
3) in Java build path i have added 'Add JARs'.
When I am adding this no error but when i build, it will show error and it is removing this jars from Java build path.
Thanks in advance,
