Out of Memory on External Processes


Oxygen XML Developer throws an Out Of Memory error when trying to generate PDF output with the built-in Apache FOP processor.


Open the Preferences dialog box (Options > Preferences), go to XML > XSLT-FO-XQuery > FO Processors, and increase the value of the Memory available to the built-in FOP option.

For external XSL-FO processors, XSLT processors, and external tools, the maximum value of the allocated memory is set in the command line of the tool using the -Xmx parameter set to the Java virtual machine.
