“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 recently ran into this error on Windows 10. It turned out that windows was looking for .dll files necessary for my project and couldn't find them because it looks for them in the system path, PATH, rather than the CLASSPATH or -Djava.library.path
