Need help with Mainframe access from Java

[SpankyJ]

First a little background:

We're creating a server based Java process, which will poll specific FTP directories for files. Upon encountering a file, the process will validate the information in the file against a DB2 database, and, if no validation flags are triggered, will format the data and append onto a dataset on the mainframe.

It's the last part which I have no idea how to do, or whether it can even be done. From a server, are there packages which will let you access datasets directly on an IBM mainframe?

Thanks!

I guessing you are looking for a JDBC driver for DB2...

If so IBM's website has the JDBC driver along with tutorials on how to use the driver.

Hope this helps.

No, I already have the DB2 access setup through the JDBC-ODBC Bridge (We can't use the IBM DB2 Java driver because we're on an early version of DB2.), what I need to be able to do is to manipulate datasets on the mainframe the way the mainframe operating system does. Think of a dataset as the mainframes version of a text file.

ok...Sorry the only mainframe I worked on had Linux installed on it (IBM zSeries)...

I think what you are looking for is called JRIO (Java Record I/O).

Does this help... Sorry I never worked on a "real" mainframe before...
