I am trying to render about 100,000 – 80 column records through FOP and it tanks pretty much everytime (OutOfMemoryException). I know iText could handle that kind of load but I can’t use it because of the LGPL license. Are there any alternative Java libraries to iText that can handle rendering a high volume of data to PDF?

There are commercial PDF generating libraries, such as BFO and ElegantJ. If you need open source, there is PDFBox, but I don’t know if it is production ready.
