Subject Ant rmic. How 'increase the memory allocated for the Java stack.' ?
Date Tue, 30 Dec 2003 15:46:27 GMT
Hi,

I am getting the following message in an ant rmic step.

[rmic] The compiler has run out of stack space.  Consider using the "-J-oss<number>"
 command line option to increase the memory allocated for the Java stack.

So I add a 'compilerarg' line to my rmic step in my build.xml as follows

    <target name="rmic2" depends="init,compile.rmic" >
        <rmic base="${classes.abcd}" stubversion="1.2" debug="on" sourcebase="${build}/rmic-source"
>
          <compilerarg value="-J-oss50m"/>
	    <include name="com/aaa/bbb/rmi/DAO/BusinessDAOImpl.class"/>		
        </rmic>
    </target> 

but when I re-run rmic I get the message 
     [rmic] -J-oss50m is an invalid option or argument.
     [rmic] Usage: rmic <options> <class names>
     [rmic] where <options> includes:
     ...
     [rmic]   -J<runtime flag>       Pass argument to the java interpreter

I have tried many variations of the line such as 
<compilerarg value="-Joss50m"/>
<compilerarg value="-J -oss50m"/>
and even 
<compilerarg value="-J-Xmx32m"/>
and
<compilerarg value="-J-Xms48m"/>

but they all give the same "... is an invalid option or argument." message.

I can put <compilerarg value="-verbose"/>  and I get lots of output during the rmic
step
which shows the compilerarg syntax is ok.

So, how do I 'increase the memory allocated for the Java stack' ?

I am using jdk 1.4.2_02 and ant 1.6.0.
I have been trying to fix this for hours and hours...

Thanks :)
