Suggestions for out of memory error on xml bean ant task?
I am trying to to build a JAR file from a _very_ large XSD file (12K lines)
on a laptop that is (unfortunately) running Windows 7 with 2GB of memory.
Both from within eclipse and from the command line, I am getting "[xmlbean]
java.lang.OutOfMemoryError: Java heap space" errors as it attempts to
compile 7604 source files after parsing the XSD. Within eclipse.ini I have
boosted the memory settings as high as I can without success.
While I realize that this size XSD is pretty excessive, our company has a
Hudson server that does successfully build this XSD-->JAR nightly, so I know
that it can be compiled given the right environment.
Does anyone have any suggestions for how I might be able to better manage
the memory to allow me to build on my development laptop?
Thanks in advance for any help.

Thank you for this suggestion. Using a different JDK hadn't even crossed my
mind. I had already bumped my memory settings up to 1024 in eclipse and it
was still failing under the Sun one. After swapping in JRockit, it worked
perfectly!

In my project , the XSD file is bigger than 1000K . But XMLBeans work very
good.
I think you shall add some JVM args. like -Xmx512m

Just an idea: I have sometimes found that using a different JDK helps, e.g., use JRockit instead of Sun's JDK.
