A requirement is to access the COBOL interface in the part II exam.

Is it sufficeint to make a note in the use case that one of the Java DAO classes are screen scrappers that accesses COBOL interface?

I know Object wrapping is another approcah.

But my reason for choosing screen scraper as the backend COBOL is not changing and object wrapping will have high development effort.

Another approach for accessing COBOL could be using the JCA.

You may take a look at this link:

JCA is the best approach because you can handle transactions if needed, which is never available in screen scrapping.

Screen scrapping as you've said must be the last option in J2ee development.

Thanks,

I am not sure if that is a requirement!

Background:...
The FBN travel agents use a legacy system written in Cobol that accesses an IMS database through 3270 screens.

Requirements:...
The IMS database will be replaced with a relational database like Oracle, Sybase or Informix.

I am not sure why would you want access the COBOL interface?
