java.lang.NoClassDefFoundError: (initialization failure)

Question

I have deployed my application in websphere server and it was working fine last week.

Class files and configuration files are not changed after that, but now when I try to access the application I get the error

I am not able to understand why suddenly the initialization failure is occuring.

I am not sure whether the issue is due to some problem in websphere server?

Are you sure you didn't remove a dependency? – Kurt Du Bois Feb 14 '14 at 07:46 — Kurt Du Bois, Feb 14 '14 at 07:46

According to your stacktrace, check this line at com.klm.solution.cargo.webpearl.library.USRUserAutherization.getSSOID(USRUserAutherization.java:109) you can find the clue.

The Debug class is used at that line. But I do not find any problem in code – user2369634 Feb 14 '14 at 08:09

The JAR containing com.klm.solution.cargo.webpearl.library.Debug is missing on the runtime classpath, not much else to say really, just check if your compile and & runtime classpaths match up.

I have restarted the server in debug mode and checked for the issue and it started working. This is very strange

Can you share with us where the jar is typically located that contains `com.klm.solution.cargo.webpearl.library.Debug` ? Is it in your WEB-INF/lib directory or is it outside of your application, for example in a directory for a WebSphere shared library? If so, is it possible this jar was manipulated / updated without any changes to your application? – Scott Heaberlin Feb 15 '14 at 02:47
