Others details are as below.

This application generates UI at run time after reading values from XML file. User uploads excel sheet which popultaes the data in table UI field. Once done, this data is transported to legacy system.

Please help as this is really urgent for me to resolve the issue.

Thank you.

Hi

I am facing this issue when I am selecting a value from drop down.

It is not giving me any error during build and deploy.

How can I check if required library files are available or not.

Moreover, I am working on sandbox which is not under NWDI.

Even if I make external Jar dc, how will I deploy that?

Regards

Vineet

HI Vikram

What version are you using? 7.0?

Please put all your poi jars inside lib. and then deploy your project.

I assume these jars are not located on your server.

If you are using Web Dynpro CE then you have to wrap your files in an ear file and deploy them.

In this case you may want to look at Walter Kahn's excellent explanation [here|;

Hi Yuval,

i'm facing the same issue.

i have already created External Library DC'c in 7.0 then added required jars from that DC to Web Dynpro Java DC but still getting the same error.

Please help as this is urgent for me to resolve this.

Thanks,

Abhishek
