Can you describe your deployment scenario in more detail?
The NPE in the above stacktrace is caused by the parent (delegation)
classloader of your org.apache.jasper.servlet.JasperLoader
being "null".
This should never happen, because JasperLoader's parent classloader
is initialized with the webapp's classloader. So for some reason, the
webapp's classloader is null in your case.
Did your webapp deploy without any errors?
Thanks,
Jan
