OpenVMS and Java

[Lance Evert]

Is it possible to read files on an OpenVMS system from a Java application running in a Windows server environment? If so, are there requirements for packages or software to be loaded on the machine? Can you point me to documents showing how to connect?

It depends on the business requirements, OpenVMS version, layered products, platform and budget.

If you provide some basic information version information, licensed layered products (UCX or TCPIP), VAX, Alphaserver or Integrity system and the format of the the files you'd like to access a more detailed response could be available.

Java and Windows are largely irrelevant to the question, but I'm guessing those tools are part of your comfort zone here.

As is common, you need to sort out the common pieces between the ends of the connection.

Guessing that this is one of the usual questions that arises here, look around for the previous discussions of ODBC and JDBC tools and (for this case) a server that allows you access to RMS files. There are several options here, including commercial options which serve direct access into RMS files to most any remote box that can connect.

If not, then it is entirely feasible for a program to toss FTP queries and pull and push files, or to use the CIFS server that's available on VMS and access served files, or to use the WebDAV remote storage server that's available within Apache, or any number of other permutations.

Or for that matter, there are mechanisms which allow distributed transactions and remote database access, if that meets your requirements.

Google is going to be your friend here, and now you have some keywords to search for.
