How to specify -mx with wsdl2java?

weingrub Mar 2, 2009 4:52 PM

Hi -

I am trying to run the wsdl2java script (because I cant get it to work from within CXF tooling) directly, with the -compile option, using something similar to:

./wsdl2java -db xmlbeans -server -impl -keep -ant -verbose -validate -compile -d /Users/marcel/fuse_wcs/cxf-wsdl-first/wsdl-first-cxfse-su/target/jaxws -classdir /Users/marcel/fuse_wcs/cxf-wsdl-first/wsdl-first-cxfse-su/target/generated/classes /Users/marcel/fuse_wcs/cxf-wsdl-first/wsdl-first-cxfse-su/src/main/resources/wcs1_1_2.wsdl

and i am running out of memory. Changing the -mx option to a bigger number in the wsdl2java script itself has no effect.

Any ideas?

Thanks! -- Rob

If you open the wsdl2java script in a text editor you can see it has the Java heap size hardcoded:
"%JAVA_HOME%\bin\java" -Xmx128M ...

You can change the maximum heap size there, perhaps give it up to 512M in case of really large wsdl files.

Thanks for the response, however, as I said, that doesnt help. I change the -Xmx2048m (2 gigs!) and even that has no effect. I dont think the memory options is being passed to the compiler....

Oh I seem to understand now. The problem is the java compiler that gets kicked off because of specifying -compile to wsdl2java. It is this Java compiler that runs out of memory, correct?

I just checked the source code and there is currently no option for specifying a Java heap size to be used by the compiler.
I consider it a valid enhancement and have raised CXF-2081.
