Ok. If there are no new ways of adding the classloader of EJB:s deployed
through an ear with a scoped repository this means that dynamic rmi
classloading will not work for these EJB:s as far as I can see it.

Re: [JBoss-dev] Remote class loading servlet
Hi Peter,
This was not a requirement for the servlet and I haven't included it -
see previous mails. Scott is deciding how we will integrate the servlet
into the JBoss startup script and retire the WebService. He might best
explain how this will be addressed.
Rgds,

It effectively replaces WebService and WebServer (WebService
simply wraps WebServer). WebClassLoader doesn't have a dependency on
WebServ* so it can operate as normal. I ran the DynLoadingUnitTestCase
and it passes. Funnily enough it passes if it succeeds with
./build.sh -Dtest=jrmp tests-client-unit
but fails with
./build.sh -Dtest=jrmp test
I think this is how it's supposed to be called at any rate.
A couple of points:
1. I didn't implement addClassLoader - AFAIK Scott said we will use the
servlets class loader to retrieve all classes. Removing addClassLoader
doesn't appear to cause a problem.
2. The WebServ* classes should be removed.
3. run.sh/run.bat will have to be updated with
-Djava.rmi.server.codebase=http://localhost:8080/class-loader/
4. Do we need to have a jmx service for this?
I've been working on the 3.2 branch but it should work with 4.0. I have
been using my own xdoclet ant script to build it as a .war - do you want
me to use another deployment script as a template?
I'll have some time over the next couple of days to write a compliant

This is a fairly simple piece of code and shouldn't take longer then a

Re: [JBoss-dev] Remote class loading servlet
Hi Dain,
I wrote a servlet (attached) and it looks like it will simplify
things.
It effectively replaces WebService and WebServer (WebService
simply wraps WebServer). WebClassLoader doesn't have a dependency on
WebServ* so it can operate as normal. I ran the DynLoadingUnitTestCase
and it passes. Funnily enough it passes if it succeeds with
./build.sh -Dtest=jrmp tests-client-unit
but fails with
./build.sh -Dtest=jrmp test
I think this is how it's supposed to be called at any rate.
A couple of points:
1. I didn't implement addClassLoader - AFAIK Scott said we will use the
servlets class loader to retrieve all classes. Removing addClassLoader
doesn't appear to cause a problem.
2. The WebServ* classes should be removed.
3. run.sh/run.bat will have to be updated with
-Djava.rmi.server.codebase=http://localhost:8080/class-loader/
4. Do we need to have a jmx service for this?
I've been working on the 3.2 branch but it should work with 4.0. I have
been using my own xdoclet ant script to build it as a .war - do you want
me to use another deployment script as a template?
I'll have some time over the next couple of days to write a compliant
build script and make any other changes you may want.

Re: [JBoss-dev] Remote class loading servlet
You won't find this in the servlet spec. "SomeClassName[some/object/id]/some/file/path" is a JBoss convention for specifying Java classes and resources dynamically downloaded by clients. It is used by org.jboss.web.WebClassLoader and by org.jboss.iiop.WebCL.

Re: [JBoss-dev] Remote class loading servlet
The IIOP tests also rely on remote class loading. They should still work after the simple web server is replaced by a servlet. (The *-iiop tests run on a server with configuration 'all'.)

You don't have to worry about class loaders. Just use the thread context class
loader.
Sorry I wasn't clear on this - WebServer has the following method
/** Add a class loader to the web server map and return the URL that
should be used as the annotated codebase for classes that are to be
available via RMI dynamic classloading. The codebase URL is formed by
taking the java.rmi.server.codebase system property and adding a subpath
unique for the class loader instance.
@see #getClassLoaderKey(ClassLoader)
@param cl, the ClassLoader instance to begin serving download requests for
@return the annotated codebase to use if java.rmi.server.codebase is set,
null otherwise.
*/
public URL addClassLoader(ClassLoader cl)
And it's called by WebService's
/**
* @jmx:managed-operation
*/
public URL addClassLoader(ClassLoader cl)
{
return server.addClassLoader(cl);
}
Hope this clarifies my original points

Subject: Re: [JBoss-dev] Remote class loading servlet
Hi Dain,
I had a look at the class and it looks like it should be pretty easy
to do this in a servlet but the deployment may be an issue. The API
includes setPort, setBindAddress, etc. Is there an abstract factory to
create a Tomcat Connector/Jetty Adapter (or whatever the container may
be) at runtime? If not is is okay to just default to 8083 and configure
the port in the service xml config file?
The problem is also complicated by the fact that we need to add and
remove ClassLoaders dynamically and WebService will no longer hold the
instance of WebServer (unless there is an abstract factory).
You were looking for a volunteer and you get an essay :)
