Oracle + Designer Template => LC Output

Hello!

A client wishes to automate his PDF generation processes, now done manually (!).

So the idea is to read data from Oracle, generate XML, combine with LC Designer templates and generate the PDFs to be made available online on a website.

Now, there will be several different templates and data will be fetched from different table-fields combinations for each templates.

Question: how do I get the info from Oracle? JDBC?

Is there any example online I could use to learn how to do it?

Thanks for any ideas!!
