OpenSAML user discussion

I have a Java program in which the first interesting thing I do is to 
instantiate a SAMLNameIdentifier.  SAMLConfig.verifyUsableXmlParser() throws 
a javax.xml.parsers.FactoryConfigurationError exception and states "OpenSAML 
requires an xml parser that supports DOM3 calls. Sun JAXP 1.3 has been 
included with this release and is strongly recommended. If you are using Java 
1.4, make sure that you have enabled the Endorsed Standards Override 
Mechanism for this parser (see 
http://java.sun.com/j2se/1.4.2/docs/guide/standards/ for details)."

One of the OpenSAML documentation files states "There is a known issue with 
JDK 1.4 because it includes obsolete XML code inside the JDK itself.  The 
workaround for the issue is to copy the JAXP jarfiles from the endorsed 
folder into your JDK's 'endorsed' class library location, typically 
'$JAVA_HOME/jre/lib/endorsed'".  So, I copy resolver.jar, xalan.jar, 
xercesImpl.jar and xml-apis.jar from the OpenSAML 'common/endorsed' directory 
to the directory they specify, and, for good measure, make sure that they are 
replaced in *any* directory these files appear.  When running my program from 
a command line, I also tell the library to override the default parser by 
specifying the "-D" option, as follows:
  java -Djava.endorsed.dir="c:\program files\...\common\endorsed" mylib.MyTest

Of course, I still get the exception.  Does anyone have any idea why, and 
(preferably) how to make sure the correct version of the library is specified 
to avoid the situation that causes the exception to fire?

Note that I am using j2sdk1.4.2_07.

Any help would be much appreciated.  Thanks,

Dan Lanz


p.s. Just an extra note: if I run 'java org.apache.xerces.impl.Version' it 
responds with 'Xerces-J 2.7.1'.  If I specify the override, as follows: 'java 
-Djava.endorsed.dir="c:\program files\...\common\endorsed" 
org.apache.xerces.impl.Version' it responds with exactly the same version.  I 
also attempted to explictly specify the Xerces Jaxp factory when I tried to 
run my program from the command line, as follows: 'java 
-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl"
 mylib.MyTest', all with the same result.
