Out of memory error - WLW Schema Project build

Question

hi
Wasn't sure which group (workshop vs xmlbeans) but here goes.
I'm doing a persomal eval of the WLS 8.1.1. platform.
My current focus is on XML Schema support, XML Beans, transformations etc
and in particular how it all copes with large schema.
I'm using Justice XML Data Dictionary (3.0.0.0) as an example of a large
schema
(http://it.ojp.gov/jxdd/)
I am getting an out of memory error when I build this within WLW.
The build appears to be in the javac phase (and occurs when the memory goes
over 256M) so I think it's the ANT task.
WLW doesn't seem to be running out of memory and the build machine is not
running out of resources.
Where do I configure this? The <xmlbean> tag ? Is there any doco?
regards
Jim Nicolson

hi Kevin
Thanks I'll take a look there.
I think it's a good move to make XMLBeans open source.
(I've been using Castor for the same purpose for the last two years).
I was mainly focussed on XMLBeans as they are used in WLW context and my
testing suggested that I would probably want to know more about the ANT
build/tasks etc. (Just to be able to deal with unexpected issues)
It's not urgent - I'm just doing a personal eval to come up to speed with
WLS 8.1 platform.
thanks

Hi Jim,
Well, the XMLBean docs are in a process of moving into the Apache
XMLBeans
project (http://xml.apache.org/xmlbeans), so I can point you to where
they
are in the cvs repository. You can also look at the source if you'dlike!

As to your second question about WLW becoming unresponsive, after the
Schemas.jar is built, the source for the entire project is re-scanned
which could take several minutes. The performance impact of rescanning
the project is improved in SP2 and will be addressed even more in future
releases. Stay tuned.
