Hi

I am trying to track down a "java.lang.OutOfMemoryError: Java heap
space" exception in my application.

I am not sure exactly where the problem lies, but possibly something to
do with CodeGenerationEngine.

My program generates web-services on the fly, and I use Axis2 to help me
along. The out of memory problem occurs if I am generating lots of
web-services in a loop.

For example, if I write a large loop like the following, I get an error.
(Note this is a boiled down version of my actual code which does a lot
more stuff - and usually I get the exception after 20 iterations or so).

Am I doing something wrong here, or is there a limitation with the
CodeGenerationEngine?


String[] parms =3D new String[] {"-o", "c:/temp", "-sd", "-ss", "-S", =
".",
"-R", ".", "--noMessageReceiver", "--noBuildXML", "--noWSDL", "-uri",
"c:/temp/exmployee.wsdl" };

CommandLineOptionParser parser =3D new CommandLineOptionParser(parms);

try
{
    for (int i=3D0;i<400;i++)
    {
        CodeGenerationEngine engine =3D new =
CodeGenerationEngine(parser);
        engine.generate();
    }
}
catch (Exception e)
{
    System.out.println("Error " + e.getMessage());
}

Thanks,
Peter
