Talking to Navision with Java

Well, I've been tasked with giving end users the ability to see and modify reports that come out of our Navision Attain system over the Internet.

Me having a lot of J2EE knowledge, would like to use Java to integrate with Navision.

Me being a total newbie to Navision, has no clue on how this can be done!

Now, we use a SQL Server database to drive Navision, and I can get to that using JDBC, but there are going to be those times when I will need to ask Navision for the information directly. I guess I can use JNI to make calls to Navsion to generate the information, and then store the results out in the database.

In short, is there any documentation or a tutorial available telling me how to communicate with Navision through Java? Heck, I'll even take some doucmentation telling me how to communicate with Navision using VB or C++ or ....well you name it! I just need something that shows a higher level language communicating with Navision Attain to request and submit data.

Thanks!
