need help to build java development component

[Former Member]

i have developed a java development component. I am using eSWT controls in it. The basic idea is to create a swt control which can be embedded into webdynpro mobile. But thats the later part. i am getting buildd errors for the library files when i try ot build the development component.

This is not during regular building project. When i chosse development component and then build from the context menu (right click) fo project it gives me these errors.

i have pasted the log details. Please guide me as to what the problem is.

Hi,

I think you are using some external library other then provided defaultly.

If you are doing that .

You have to create a DC of type External library.

And add the component as used component in the main webdynpro component.

Thanks & Regards,

Lokesh
