I am using servlets and a third party API to gain access to our 3270 mainframe transactions. I have gotten a few to work OK but have a question. If I send form field parameters to a servlet, it passes the parameters to methods in other classes which call the mainframe screens. Then I "scrape" the returned screen and feed the screen rows into Vector elements which are passed back to the servlet for html display. Now, what happens if the user has entered invalid data in the form fields in such a way that the correct mainframe screen is not returned? I need to be able to respond back to the user 1) the error returned, and 2) what is now expected. Then, I need new (or modified) form data from the user and then, still within the confines of the same "session", feed the new or modified data into the appropriate MF fields and complete the transactions so I can then continue to get the correct returned MF data. Is this something that servlet sessions handle? Any suggestions on the best (read easiest for novice) approach to this situation would be greatly appreciated!!! Along the same lines, this sort of thing could be used so the user could run any number of mainframe transactions after logging on. Each servlet or html page could check whether a MF authentication was validated at the beginning, and then is passed along, until a button is pressed to initiate the mainframe code to actually logoff completely. Sorry for rambling on and I know this will not apply to most, but I figured I would find the answer here. I would also be interested in hearing from anyone using servlets for mainframe interaction.
