Hi Friends,

I have created an DC application where i read data from excel.For this i have used jxl.jar.I have created External Library DC and add this jar to it.

Now i have added the External Library DC to the actual application.

I dont get any compilation error.But when i execute it im getting the following error.

java.lang.NoClassDefFoundError: jxl/Workbook

at test.com.wdp.InternalExceldataView.<init>(InternalExceldataView.java:121)

Hi,

I checked in my server but i dont have a option called Javascript(Rhino)Library.

Is there any other way to check for the library reference.

check in vsual administrator in libraries with name poi jars.

other wise do one thing

create a new project of type j2ee servercomponent-->library

open server-provider.xml

give providername =sap.com

component name=poijars

display name=poijars

select jars tab-->add jxl.jar

right click on proj build library archive , deploy the sda file

now add library reference for your wd project =sap.com~poijars

Hi Naga Raju,

I found the solution where i create the J2ee project deployed sucessfully.

i also refered the visual administrator and specified the same in the library reference.Im not getting the warning during deployment but still facing same problem.
