Increasing compiler memory in Build.xml

["Richey, Ross" <ri...@aruplab.com>]

I'm using the webapp compilation script I found on
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html to
compile a servlet zone.  But It appears that Javac is running out of
memory:

-----Output-----

Buildfile: build.xml

jspc:

compile:
    [javac] Compiling 16726 source files to
/usr/local/tomcat/jakarta-tomcat-5/build/webapps/ROOT/WEB-INF/classes



    [javac] The system is out of resources.
    [javac] Consult the following stack trace for details.
    [javac] java.lang.OutOfMemoryError
    [javac] Compile failed; see the compiler error output for details.

all:

BUILD SUCCESSFUL
Total time: 40 seconds

-----/Output--------

Ideally I'd like to include a directive in the build.xml to increase the
compiler heap, but I haven't been able to find any directive that does
that.  What I have found are instructions for increasing the memory via
the command line, '/usr/local/jdk1.4/bin/javac -J-Xms=256m -J-Xmx=256m',
but that returns:

Invalid initial heap size: -Xms=256m
Could not create the Java virtual machine.

I'm running Redhat 7.3, Tomcat 5, Ant 1.6 and j2sdk 1.4.2.
