Hallo Garanting,

To resolve the issue you are getting, use the following strategies:

  • First, you will need to review thejava.lang.NoClassDefFoundError error and establish the classes that are missing.
  • After that you will have to verify and then  locate missing Java class from your compile / build environment.
  • And then you will have to find out if the missing Java class is from your application code, is a third part API or even the Java EE container itself. Check and see where the missing JAR file should be found
  • After that you will need to verify the runtime environment Java classpath for any typo as well as missing JAR file(s)
  • In case the problem is triggered from a Java EE application, then you will have to perform the same steps, but this time round you will have to verify the packaging of your EAR as well as WAR file for missing JAR and any other library file dependencies, for instance MANIFEST
