OpenSAML user discussion

hi all,

I am trying to develop the SAML2 support in Apache Rampart. While trying to 
build an assertion, the following exception is thrown when trying to invoke 
DefaultBootstrap.bootstrap() method.

---------------------------------
ava.lang.UnsupportedOperationException: This parser does not support 
specification "null" version "null"
     [java]     at 
javax.xml.parsers.DocumentBuilderFactory.setXIncludeAware(Unknown Source)

-------------------------------------

I have already endorsed Xerces and Xalan. I am using JDK 1.5 and Xerces 
2.9.1. One interesting point is that I have a simple program that creates a 
assertion using the hard coded parameters, and that works fine. Once I added 
this to my main program, I started to hit this error.

I saw this error has been reported sometime back to this list[1], then the 
solution provided there is to endorse the JAXP implementation. But I have 
already done that and it works fine for me in one scenario. I checked the 
classpath while the erroneous program and it seems that the endorsed jars 
have been picked up.

It would be really appreciated if someone can guide me to the solution.

Thanks in advance.

best regards,
thilina
