Error trying to access web interface on jboss-6.0.0.m3 under Windows

[stwhit]

I've downloaded jboss-6.0.0.m3 to Windows and started it.  Then, I tried to access the web interface by opening localhost:8080 in my browser (from the same computer), but I just get a blank page in my browser, and in my console I see this log message:

19:45:10,722 ERROR [org.apache.catalina.connector.CoyoteAdapter] An exception or error occurred in the container during the request processing: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getEffectiveSessionTrackingModes()Ljava/util/Set;

When I try to recreate this problem on linux, it does not happen.  The web interface appears as expected.

Anyone else seeing this behavior?

That's strange. Is this a clean installation? Which exact Windows OS? And which version and vendor of Java do you use? Can you post the logs that you see on the console (not the server.log) from the time you start the server?

Thanks for your response.  You pointed me in the right direction.  It turned out my jdk wasn't a clean installation.  I had copied servlet-api.jar into its jre/lib/ext directory a few months ago and I think that was causing this problem.  With a totally clean jdk the problem goes away.
