I'm hoping that we can move at a much faster pace then every 6  
months.  I personally would like to see a release every 6-8 weeks  
with at least one big new feature.  We have a lot of features to add  
to it seem reasonable to me that we can focus on getting something  
big to the users on a regular basis.

* Finish the debug console
We should be able to start and stop services, set properties and  
invoke via the kernel interface.  This shouldn't take more then a day  
to finish.  Maybe someone with some GUI skill could whip up a new  
layout for it, as it is a bit ugly.

* reference docs
This is not really user docs.  It is just a list of every  
configuration option and what it does.

Yep.  I think this goes with the hot deploy directory above and the  
ability to support unpacked "in-place" deployments.  The key part of  
that description is in-place.  Currently we support unpacked  
deployments but copy all the files to another location.

I think this is "table stakes" for CMP.  I'm not sure if people are  
willing to hold up 1.0 to do all of this, since almost no one uses  
CMP, but before we claim we have usable CMP we need all of these.

I'm working on this, so I planing on having it in anyway :)

Most people use it and it should be a trivial conversion of our maven

* Alternate spring based assembly

I'd like to have an additional spring based assembly available  
quickly, but I don't see reason why it should holdup a 1.0 release of  
the normal server assembly.  The spring based assembly removes the  
desperate need to create tools to deal with the compiled  
configurations, since the configurations are available for direct  
access via a text editor.

There may be a technical reason we have to move to xmlbean v2 before  
Geronimo 1.0, but if not I'd put in the nice to have category.

> - Make sure tx recovery works and build a UI for reviewing problems

I would expect some minimal work in this area for 1.0, but I think we  
should nail this one down in the 1.1 timeframe.

I completely agree with the sentiment, but I think you are setting  
the goal way to high.  Since people haven't been pounding on or  
working with these apis much, I don't think it is possible not not  
change the interfaces.  Heck the discussion on shutdown hook ordering  
in the Kernel will most likely require an API change, and this is one  
of the most used an inspected interfaces in Geronimo.

A good installer would be cool to have.

Not sure we need this until there are some tools that support dd  
beans. For all I know there could be some now, but I remember last  
time we talked about dd beans there were no tools (other then netbeans).

Not sure what you had in mind here.  I doubt you mean that XML  
hacking is not possible, or that is would be a high tech xml editor.   
Do you have more detailed description, or better yet, can you point  
to some tool that does what you are thinking of?

I think this goes with the above section.  I don't mind editing xml.   
Heck it works for Apache httpd and Apache Tomcat so I don't see why  
we wouldn't support it.  On the other hand, I don't think it should  
be the only way.  I'm just no clear on the other alternatives our  
users want to see.

I don't think this is something we can put on the road map; it is  
just something we do.
