Certainly, take a look at
XmlBeans.typeLoaderForClassLoader()
XmlBeans.typeLoaderForResource() and
XmlBeans.typeLoaderUnion()

Subject: RE: Help with XML Beans
is it possible for me to have a separate resource loader for
.xsb? it looks like JNLP class loader is not thread safe. It is trying
to call "put" on HashMap but hash map is not thread safe. It may cause
the CPU to spin. Please advice and it is really appreciated. We are
really happy with xml bean performance but this issue is causing lot of
noise on our side.
Thanks for your time.

Subject: RE: Help with XML Beans
In this case: two threads are parsing two different byte arrays
to generate java objects. yes, xml bean is looking for a .xsb resource
but it is spinning. I don't set unsync option, so what is the default
behavior?
we use xml beans 2.3.
we don't validate the using xml bean. What we have is server is
generating xml using xml beans and send it over http. The client is
reading it off the output stream and generate bytes array and try to
parse using xml beans.

Subject: Re: Help with XML Beans
So your application is "generating xml messages or parsing byte
arrays
to generate java objects"? Can you determine which one? From the
stack
trace you posted is looked like XMLBeans is trying to resolve
something from the SchemaTypeSystem and the hang is caused by
the way
JNLP is getting the resource. Can you confirm? Which resource is
it
trying to get?
What is the option you have set for
http://xmlbeans.apache.org/docs/2.0.0/reference/org/apache/xmlbeans/XmlO
ptions.html#setUnsynchronized()
Which version are you using?
Is it possibly related to:
http://issues.apache.org/jira/browse/XMLBEANS-46
http://issues.apache.org/jira/browse/XMLBEANS-328
http://issues.apache.org/jira/browse/XMLBEANS-345
(it didn't look related, but I thought I'd mention anyways)
