[xep-support] Re: Generating DITA PDF from oXygen

[David Hollis]

Hi Danny,

Firstly, this is not an XEP issue, it's a DITA-OT and its use of Java issue. There are plenty of support lists and forums for DITA, and also for oXygen.

To use XEP with the DITA-OT, you need to set both JVM AND maxJavaMemory.

To quote from the thread: The values I used were: maxJavaMemory=1024m and JVM=-Xmx1536m

You can use the oXygen DITA-OT interface to add maxJavaMemory.

Cranking up JVM to 10G or 12G is what I did, and it's wholly unnecessary.

The default for maxJavaMemory is something like 512m, and it's not enough.

HTH,
David

> I’m able to take the FO that is generated with the transformation and run XEP on the command line and I get the PDF output. I’ve bumped the oXygen available memory up as well as the Advanced tab on the transformation and it doesn’t seem to make any difference. Any idea on how to correct this?
