out of memory with javac

[ch...@polaris.co.in]

Hi,

The following is a code snippet from my build file
   <javac
                        fork="true"
                        memoryMaximumSize="1000m"
                        executable="${was4.home}/java/bin/javac"
                        tempdir="${basedir}/TEMP"
                srcdir="${basedir}/APP/SOURCES" destdir="
${basedir}/APP/CLASSES" >
                <classpath >
                <path refid="build.classpath" />
                </classpath>
        </javac>

This task fails with an out-of-memory exception.
However, the equivalent command on the shell prompt works without a hitch -
javac -J-mx1000000000 -d $TEMP_SOURCE *.java.
I have even tried the following alternatives
1. Running javac within the Ant JVM ( fork = "false" )  and setting the
maximum heap size via ANT_OPTS.
2. Running javac using the exec task and specifying the heap size as the
argument(-J-mx2000000000).

Nothing works; I am frankly at my wits' end. Is forking the problem here?
Any help would be much
appreciated.

Regards,
CR

hi chandra

how many files are you compiling?

try increasing the Memory size of ant process by using -Xmx in the ant.sh
file.

Hello CR,
can you say how many java files you work with? Are
they really so many?
As for yor shell command
javac -J-mx1000000000 -d $TEMP_SOURCE *.java,
I think that *.java will take only the java files in
the current dir and not all files in the package
hieararchy and thus the shell command will compile
only a part of the sources. Of course this is not an
answer to your problem. I also saw that you are using 
executable="${was4.home}/java/bin/javac"
Can you try without it?
