Hello,
I'm using DynamicPDF.jar in my project in Eclipse.
Its giving an error as shown below:
----------------------------------------------------------------
Distribution of module failed.  See log for details.
Classloader for WebApp_IDcan't find Could not fully load class: ServletSample

And a long error log.

Please tell me how to remove this error.
MyProj is the project name here...
However I'm not getting this error with NetBeans.
