Catalina. Class Loader problem. java.lang.LinkageError: duplicate class definition

["Roytman, Alex" <ro...@peacetech.com>]

Hello,

I am getting this error when hit my web page first time. What is the
most puzzling that after few retries it works no more errors. There is
no duplicate class paths in my class path and WEB-INF/class(lib)

I would really appreciate if you can point me in right direction

Alex
