I have just started using JAVA and have decided on the servlet approach for
several reasons. I am developing servlets to put a new face on our existing
CICS mainframe transactions with the help a third-party JAVA toolkit. So far
so good. I finally got interaction between the html forms and the mainframe
transactions.
Session management and servlet life span will be some of the big issues I
can see so far. I guess I have not worked with it enough to know how to
handle the situations yet. When a user enters form parameters and submits
the page, the servlet runs, connects to the mainframe, starts the CICS
transaction, fills in the fields and returns the results. But what happens
then? Is the servlet still running "somewhere"? For how long? What if I want
to pass more info to the next CICS screen that appears? Or move from CICS
screen to screen getting data from the html form and proceeding to the next
html page? I need to make sure another user running the same transaction
doesn't "jump in" and the screens get mixed up.
Also, is there a way to pass parameters to the servlets without them
appearing on the URL address line? I can get this to happen with a CGI type
of program I am using to access and update ODBC databases so I know the
process is generally possible but not sure about servlets.
I hope these questions are appropriate for this forum. Please let me know if
not.
Thank you
