Subject RE: Tomcat 7 LifecycleBase.init
Date Mon, 01 Nov 2010 16:34:49 GMT
Sorry for the noise. 

Once I got the right source code, it was pretty easy to track under a debugger. I needed to
implement Context.getName(), getPath, an Engine and a Pipeline.

		_authenticator = new NegotiateAuthenticator();
		SimpleContext ctx = new SimpleContext();
		Realm realm = new SimpleRealm();
		ctx.setRealm(realm);
		SimpleEngine engine = new SimpleEngine();
		ctx.setParent(engine);
		SimplePipeline pipeline = new SimplePipeline();
		engine.setPipeline(pipeline);
		ctx.setPipeline(pipeline);
		_authenticator.setContainer(ctx);		
		_authenticator.start(); 

It would be nice if Tomcat's code was a bit more defensive in terms of nulls.

Subject: Tomcat 7 LifecycleBase.init

I have some unit test code that mocks a lot of Tomcat classes so that I can test a Tomcat
Valve (code in http://waffle.codeplex.com). Switching to Tomcat 7 is giving me some grief.
I used to be able to do this:

            SimpleContext ctx = new SimpleContext(); // my class
            Realm realm = new SimpleRealm(); // an empty realm
            ctx.setRealm(realm);
            _somevalve.setContainer(ctx); // valve container
            _somevalve.start();

Now I am getting this

java.lang.NullPointerException

                at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

The problem is in MBeanUtils that assumes that a valid container object is passed into it
(from ValveBase.getObjectNameKeyProperties). I tried to walk this code and I don't understand
how I am supposed to setup container (and possible its parent(s)) to not get this exception.

What am I missing? Any help is appreciated,

Thx
