What version of Tomcat are you using?

Let's take a look.

Good. You shouldn't use mod_jk2 for anything. Use mod_jk instead if
you actually need to use a non-HTTP connector.

What is Listener.service.port set to? 9010?

Calling Tomcat.getConnector() will create an HTTP connector if one was
not already added. From the Javadoc (emphasis mine):

"Get the *default http connector*. You can set more parameters - the
port is already initialized. Alternatively, you can construct a
Connector and set any params, then call addConnector(Connector) "

Ref:
http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/startup/Tomcat.html#getConnector()

> What I am doing wrong?

You should probably start with a new connector and add it yourself.
Once a Connector object has been created, you cannot change its protocol.

Try this:

Connector c = new Connector("AJP/1.3");
c.setPort(...);
...
tomcat.setConnector(c);

Hope that helps,
