Unable to view EDI DocumentType in TN45

I am unable to view EDI document types using TN Console. I am able to view XMl document types without any problem. The error i am getting when i doubleclick the EDI document type is:

“The class for the document type that you are trying to edit is not found in the classpath. Please make sure that the classpath is set up properly.”

What classpath should i be setting…
