Implement 3270 protocol in Java

Question

I\'ve got a big problem with IBM HACL for accessing a server which speaks 3270 protocol. The library keeps crashing, and our JNI wrapper is actually a bug-fixing layer for the p

Answer 1

Another option would be h3270. It is a Java front-end to the x3270 suite of tools.

Answer 2

http://tools.ietf.org/html/rfc1041

so i guess its documented (assuming i hit the right doc) couldnt find a java implementation though, you'd need to code it over telnet, or maybe SSH

Answer 3

I am unfamiliar with the differences between 3270 and 5250 data streams, but there is a 5250 implementation in Java in the tn5250j project available from http://tn5250j.sourceforge.net/

It might be usable for you?

(also there is a 3270 screen scraping project at http://freehost3270.sourceforge.net/ but it appears to be abandoned).

Answer 4

Freehost is not good code. Do not even bother trying it. There is a reason that it seems dead. JIN TN3270 is better but is incomplete. Ideally you want to find the API that your company's Emulator software uses. I am still searching for one for ours.

Answer 5

freehost3270 doesn't look as abandoned as it might appear - CVS has changes from 2 years ago. There is always an arguement that good code won't need to be changed that often in any case if the requirements have not altered. There have been complimentary comments wrt to the codebase. If you don't particularly want to work with other vendors products then working with this code/project seems to be your best option.
