“NoClassDefFoundError: Could not initialize class” error

Question

When I run my project, I get numerous outputs of this error:

Sep 9, 2009 8:22:23 AM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service()         


        

Answer 1

I had faced the same issue, because the jar library was copied by other Linux user(root), and the logged in user(process) did not have sufficient privilege to read the jar file content.
