Brent, Many Thanks for pointing the DefaultBootstrap.bootstrap().

 

I have added "DefaultBootstrap.bootstrap();" in my code and could see the below error in the output:

==================================

I have endorsed the files in tomcat(copied complete "endorsed" folder from downloaded opensaml2.0 to c:/apachetomcat/) and jre(copied complete "endorsed" folder to myeclipse/jre/lib).

As I am getting the error in web application, I tried to test the same code as standalone and can see different error as below.

For the Stand alone application I have the slf4j-api-1.5.0.jar in the build path.

==================

[org.opensaml.DefaultBootstrap] : Initializing Velocity template engine
[org.opensaml.xml.Configuration] : VM using JAXP parser org.apache.xerces.jaxp.DocumentBuilderFactoryImpl

 at org.opensaml.DefaultBootstrap.bootstrap(DefaultBootstrap.java:75)
 at utils.Main.main(Main.java:35)

==================

 

If I remove the "DefaultBootstrap.bootstrap()" in the standalone application, I can see the "Exception in thread "main" java.lang.NullPointerException " at the line "inCommonMDDoc = ppMgr.parse(in); ".i.e, the "inCommonMDDoc " is null. I am sure the input file path is correct and is not empty.

Please help me with your inputs to get this resolved.

 

Thanks and Regards,
Murali

I don't see anything obviously wrong with what you doing vis-a-vis the
XML parsing.  Not much can go wrong there, it's not even the opensaml
code, just JAXP.   So check that that is the correct filename, that the
file isn't empty, etc.

Are you sure the error is from that line?  I don't see you calling
DefaultBootstrap.bootstrap() in your code snippet.  Failing to bootstrap
the library that would most likely generate an NPE a few lines down,
where an attempt would be made to use  the (null reference) unmarshaller .
