RTF Export Template: Throwing exception Out Of Memory (Java Heap)

[schir1964]

I think the RTF code is too large (12 Megabytes) and is causing the program to run out of space for processing.

 

Here's the exception being thrown.

Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space

The plan was to just dump out the original RTF untouched to see if looked okay and then start replacing the hard coded values with Export Tags. The dump worked but it was corrupted with the empty line prepended to it due to the Export Tags being remove (the file description and so forth).

I then went to remove the spaces the from file using the Regular Expression Replace tags. That's when this error began being thrown. Even after I removed the replacement tags it still threw the out of memory error. Even after shutting everything down and restarting it throws the error now.

I just used one his sample RTF files to fill in the HeroDesigner export fields to create the template.

For character image you need to edit the RTF file in Word or some other program and add it yourself.
RTF requires the image be encoded and embedded in the RTF file.not get split in half if it overflows the existing page.

Any thoughts?

 

 

trace.log appPrefs.xml

There are no errors shown in that trace.log file. Either the trace.log file is not from the HD installation that's throwing the error or the error is due to HD/Java not having access to the directory that you're trying to run from.

Sorry, I was thinking the trace.log was only created when an error occurred. I wiped out the error when I updated this post. So it does seem related to the RTF Export Template. I'll reproduce the error and update this thread appropriately.

I've reproduce the error and updated the post accordingly.

Increase the memory available to HD (under app preferences)

[schir1964]

Just confirmed my theory. If I trim down the RTF Code the Exception isn't thrown and the file is generated. Guess I got lucky the first time I ran the export.

Thanks, I'll try that.
