Problem with Lemur

Troubleshooting General Help
1

I am trying to use Lemur to create GUI.
Here is the error:NoClassDefFoundError: org/slf4j/LoggerFactory when initialise the GUI.

Can anyone help with this?

Think through the problem:

  • What jar file should that class be found in?
  • Is that jar included in the libraries that are available to your application at runtime?
  • if not, how was it skipped?

You are missing the slf4j library which is required by lemur.

EDIT:
Check the prerequisites because you might be missing other jars as well.
