Subject: adding servlet definition to context on the fly :Tomcat 5.5
Hi,
I had written some code to dynamically add a servlet to a context in a
deployed applicaiton in Tomcat 4.1. This code basically uses the catalina
loader to obtain the server->engine->host->and context, and invokes the
addChild method after configuring a StandardWwrapper to represent the
servlet I am adding. This all works fine in Tomcat4.1 and I am able to
access the servlet through the right url immediately, without having to
restart Tomcat.
I'd luv to see that code... the stuff you playing with is in Tomcat core...
must have been difficult to debug... perhaps its an embedded app?
But I think this answers your question...
public void addChild(Container child) {
throw new IllegalStateException
(sm.getString("standardWrapper.notChild"));
}
is what addChild now looks like in 6... if they did allow it, now they
dont (;
Dont think you can blame TC... whoever made that app was doing open heart
surgery ;)
I've never tried this, but its really interesting... I think I would start
by having a good look at...
HttpServlet source code... its an abstract class with a little
introspection...
but I (think... maybe) that the way to go is to make a servlet... that does
what HttpServlet servlet does... and then load your sevlet classes into your
servlet... and call them...
I (think... maybe) maybe that it will come down to doing your own servlet
mapping... and detection of new classes added... possibly your own uri to a
"manager" function...
ie I think you can make a servlet intelligent enough to do this... without
climbing into the engine and doing a liver transplant... and then because
you now inside the official API... this will never happen again.
In the end it will be something like
http://domain/contect/addons/ANY_ADD_ON_SERVLETS
... I'd give that a bash... dont think its a good idea trying the current
method even if you do find an open vein ;)
Good Luck...
