Subject Geronimo/Spring integration - Deployer checked in...
Date Fri, 28 Jan 2005 00:22:20 GMT

I have just checked in the beginnings of a SpringDeployer (revision 128446).

This requires an updated version of Spring (1.1.3). So, if you tend to
run your builds offline, you will need to hook up and let maven sort
it all out.

A Spring deployable currently looks like this - e.g. :

foo.spr/
    META-INF/spring.xml
    Foo.class
    Bar.class
    ...

Classes should be deployed unpacked at the top level of the jar :

You should run the org/apache/geronimo/SpringDeployer configuration in
your server to use this functionality.

The org/apache/geronimo/DebugConsole will be useful to look at GBeans
that represent your Spring apps.

e.g.

[jules@smilodon cvs]$ java -jar 
geronimo/modules/assembly/target/geronimo-1.0-SNAPSHOT/bin/deployer.jar 
--user system --password manager deploy foo.spr
Deployed
[jules@smilodon cvs]$ java -jar 
geronimo/modules/assembly/target/geronimo-1.0-SNAPSHOT/bin/deployer.jar 
--user system --password manager undeploy /tmp/deployer34206.tmpdir/foo.spr
Undeployed /tmp/deployer34206.tmpdir/foo.spr
[jules@smilodon cvs]$

output from server :

Functionality is rudimentary at the moment.

Only one GBean is created per Spring app.

We hope to add the following functionality soon :

1. Support for a META-INF/geronimo-spring.xml (internally or
externally) - this will be used to provide platform specific deploy
time metadata.

2. The possibility of exposing individual Spring generated beans as
GBeans in the Geronimo kernel with all attendant benefits -
management, monitoring and persistent configuration.

3. Transparent injection of platform hosted resources into Spring apps
- allowing seemless hookup between Spring composed apps running in
different containers within Geronimo.

4. Support for nested jars within the .spr.

5. Anything else that looks useful - please join this thread with your
ideas.


The code is in modules/spring-builder if you want to take a look.

If anyone can figure out how to move the Spring-related stuff out of
the j2ee-runtime-deployer-plan.xml and back into the
spring-deployer-plan.xml without losing the deployer they will have my
undying gratitude - I ran out of steam - maybe tomorrow :-)

We will be working closely with the Spring team on this integration. We
hope that both Geronimo and Spring will benefit substantially from
this.

Enjoy,

Jules
