WD component build error

Hi all,

In my process I have a webDynpro component in which I am uploading an xls file and populate a table. I have downloaded the jlx.jar library, added it to the build path of my component, as well as copying it in the lib folder. But when I try to build my component I get the following error message: "package jxl does not exist". Does any of you know what else needs to be done in order not to get this error?

Regards,

Stefania
