Re: Trying to embed gnu.xml.dom.DomDocumentBuilderFactory

Thanks,
There was no DomDocumentBuilderFactory entry in the output of command:
nm --demangle=java myapp.exe
even when I explicitly imported and did "new
DomDocumentBuilderFactory()" in the code.

I extracted a portion of libgcj-4.2.0.jar (the whole content of
gnu.xml.* package), say gcj-dom.jar, and compiled and linked it with
my application. The result executable has DomDocumentBuilderFactory
but this time I'm facing with NoClassDefFoundError for
gnu.xml.dom.DomImpl.
Again I put the trivial code new DomImpl() and linked the app. This
time again I'm facing with:

java.lang.NoClassDefFoundError: gnu.xml.dom.DomImpl
java.lang.Class.initializeClass(zekr_static_olpc.exe)
gnu.xml.dom.ImplementationSource.<clinit>(zekr_static_olpc.exe)
java.lang.Class.initializeClass(zekr_static_olpc.exe)
java.lang.Class.newInstance(zekr_static_olpc.exe)
org.w3c.dom.bootstrap.DOMImplementationRegistry.newInstance(zekr_static_olpc.exe)
gnu.xml.dom.DomDocumentBuilderFactory.<init>(zekr_static_olpc.exe)
net.sf.zekr.engine.xml.XmlReader.<init>(zekr_static_olpc.exe)
net.sf.zekr.common.config.ApplicationConfig.extractLangProps(zekr_static_olpc.exe)
...

It's strange that although there exists some entry for gnu.xml.dom.DomImpl with:
nm --demangle=java myapp.exe
it gives me that error.

I should also say that I tried to embed xercesImpl.jar with my app, setting:
javax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
so that it uses xerces instead of gnu.xml.*. It gives me again a
NoClassDefFoundError.

It seems that even when a class file is embedded in a static binary,
class loader (java.lang.Class.initializeClass()) cannot load that.
