Ant RMIC. How increase memory allocated for the Java stack?

Thread view:

Hi,

I am using Ant 1.5.4 and am getting the following message on my 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 stac
k.

I am trying to follow the advice in this error message from Ant, but
cant get the syntax right!

I have added a compilerarg statement to the build.xml step as below
<target name="rmic" depends="init,compile.rmic">
<rmic base="${classes.xcob}" stubversion="1.2" debug="on"
sourcebase="${build}/rmic-source">
<compilerarg value="-J-oss 5m"/>

When I run it with this get ant saying
[rmic] -J-oss 5m is an invalid option or argument.
and it says
[rmic] -J<runtime flag> Pass argument to the java
interpreter

I have tried many variations of the compilerarg line above.

I have looked at
http://ant.apache.org/manual/CoreTasks/rmic.html
and at
http://www.biostat.wisc.edu/cgi-bcg/man.cgi?section=1&topic=java

but still cant get the syntax right to increase the memory allocated
for the Java stack.

Note I am using Java 1.4.2 here.

Help!

Thanks
Stephen Chalkley.

Actually from rmic, not Ant 8-)

> <compilerarg value="-J-oss 5m"/>

There must not be any space between oss and 5. Use -J-oss5m instead.
But I'd think that 5 MB is not enough if the default value is too low.

Thanks, but I tried this and get the same message, i.e.
<compilerarg value="-J-oss5m"/>
gives message
[rmic] -J-oss5m is an invalid option or argument.

Gave up on trying to get Ant to give more space to the compiler.

Solved using the Ant exec task.
I got rmic to run in a batch file, then copying the arguments to the
exec task in the build file as follows. (path and class names changed)

<target name="rmic.exec" description="rmic of the class that fails
in the ant rmic task">
<exec executable="rmic.exe">
<arg line="-v1.2"/>
<arg line="-classpath"/>
<arg
line=".;C:\dev\views\aaa\src\java\;C:\dev\bbb\build\webapp\WEB-INF\lib\log4j-1.2.2.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\activation.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\EnterpriseJMS50.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\jms.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\mail.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\sybase.jar;C:\dev\bbb\build\webapp\WEB-INF\lib\ccc.jar"/>
<arg line="-d"/>
<arg line="C:\dev\aaa\build\classes.qqq"/>
<arg
line="com.ddd.component.objectserver.rmi.eee.myClasee"/>
</exec>
</target>
