OpenSAML user discussion

[Christoph Wagner <>]

Hi,

I'm want to use OpenSAML 2.3.1 in a Spring-based web app. I have all of the 
required libraries in the WEB-INF/lib folder of my application, including 
xmltooling-1.2.1.jar, which contains both the 
org.opensaml.xml.parse.BasicParserPool and org.opensaml.xml.Configuration 
classes, yet I get the following exception message:

javax.servlet.ServletException: Servlet.init() for servlet spring-dispatcher 
threw exception
        
org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)

org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447)
