Need to upgrade embedded Tomcat in 4.0.5 GA

[gwolfjdc]

Hello all.

I've got customer's screaming about all the security holes in tomcat 5.5 so I need to upgrade to 6.0 I've built a new .sar file for the tomcat deplymoent with the 6.0 bits in it, and change everything up to point at the new tomcat but i keep hitting a wall.

I get this exception at startup:

2010-06-02 08:16:04,409 DEBUG [org.jboss.web.tomcat.tc6.Tomcat6] Starting jboss.web:service=WebServer
2010-06-02 08:16:05,737 ERROR [org.apache.commons.modeler.modules.MbeansDescriptorsIntrospectionSource] Error reading descriptors

at org.jboss.web.tomcat.tc6.Tomcat6.startService(Tomcat6.java:332)

which traces back to this line of code:

String objectNameS =

catalinaDomain + ":type=server";

ObjectName objectName =

new ObjectName(objectNameS);

// Set the modeler Registry MBeanServer to the that of the tomcat service

Registry.getRegistry().setMBeanServer(

server);

server.createMBean("org.apache.commons.modeler.BaseModelMBean",

                                   objectName,

                                   new Object[]{"org.apache.catalina.startup.Catalina"},

                                   new String[]{"java.lang.String"});

I think the class is failing to instanciate as the Null pointer exception traces back to a call to

realclass.getMethods in the createManagedBean method of the MbeansDescriptorsIntrospectionSource class

do anyone have any clue as to why ths might be happening?

thanks
