I assume you mean running the java task with the fork attribute set to
true, not the xslt task. Nothing is wrong with using the java task, but
I thought it might be a little easier for someone else to understand if
I used the xslt task instead. But this seems like more trouble than it
is worth.
Thanks for your help!

max heap memory size is a jvm level setting that the xslt task has no control

to run it in a different jvm, Running the xslt task by setting the fork
attribute to true as you showed in the second approach is the way to go. What
is wrong with this approach?

Subject: Increase Java heap within xslt task?
How can I increase the memory for the xslt task from within Ant 1.8.4, not with an environment variable? I am using Saxon by specifying the Saxon jar classpath in this target:
<target name="commands">
<xslt in="command-spreadsheet.xml" out="out.xml"
style="intermed.xsl" force="true">
<classpath location="${saxon}" />
</xslt>
</target>
This transform job crashes with "java.lang.OutOfMemoryError: Java heap space"
unless I set ANT_OPTS=-Xmx256m. But I don't want to have to depend on an env variable. Is
there a way to increase JVM heap space within the xslt task? I can run this same
transform successfully with the java task like this, using the maxmemory attribute to
increase the heap space:
<target name="old">
<java jar="${saxon}" fork="true" failonerror="true" maxmemory="256m">
<!-- Source file -->
<arg value="-s:command-spreadsheet.xml"/>
<!-- XSLT stylesheet -->
<arg value="-xsl:intermed.xsl"/>
</java>
</target>
There is no maxmemory attribute for the xslt task. I would rather use the xslt
task if I can.
Thanks,
Mark
