Torque has just been split out from Turbine and, though lacking extensive documentation, is functional in a stand-alone mode, as is Fulcrum the service framework. Torque is in part based on the work of Scott Ambler, and I would like to move it more toward Scott Ambler's work and go further and make Torque a JDO implementation. In short I would like Torque to become a transparent persistence layer. Define your object hierarchy, have torque generate everything you need to persist your objects, and use OQL to retrieve a set of objects. Fulcrum is also a stand-alone project now and might save you some time as I see from commits that you guys are working on one too. I'm hoping that Fulcrum will also be compliant with the service framework JSR and I would like JMX enable Fulcrum shortly too. The repositories are jakarta-turbine-torque jakarta-turbine-fulcrum Both repository are laid out in an odd fashion because I just recently separated them from Turbine so they still have turbine package names because I didn't want to break everyone's code. There is only one thing in Torque left to do and than I think Torque would integrate well with Struts: the connection pool needs to be pluggable. I have decoupled everything else but the connection pool still used is the one that is included with Torque which won't work for Struts users or any other users that have their own connection pooling already. Maybe we can work together on Torque and/or Fulcrum to provide persistence and services? I know everyone needs persistence and I have decouple almost every service in Fulcrum from Turbine so they are now useful outside the context of Turbine. Some services of interest may be: BSFService: Bean Scripting Framework service CacheService: I am talking to the author of jpolycache (jpolycache.sourceforge.net) and looking at the commons cache code to replace what is currently there. MimeTypeService SchedulerService UploadService: I know you guys have some code this. SecurityService: Role/Permission based security service TemplatingService/VelocityService: You use JSP but these services are still very useful for things like templated email messages or any sort of generative task. XmlRpcService: Now based on the newly created XmlRpc code at xml.apache.org from code donated by Hannes Wallnoefer. It also now supports SSL. XSLTService: A very simple transformation engine. I know our two groups have traditionally not work much together, but maybe we can change that. There is also the Turbine Developer's Kit (TDK) which could probably be adapted for new struts users. The torque and fulcrum repositories are there if anyone is interested. -- jvz.

I think it's totally feasible. The idea of a pluggable introspector came up on the vel-dev list a couple weeks ago and that's probably a good idea and if that were done then we could probably share the introspector that's in struts. Velocity has some non-standard behavior like picking values out of Maps, but the introspector proper could probably be shared without much work. If I could get the struts introspector working in velocity maybe we could make that the first tool placed in the org.apache.util package! :-) We'll show them we can play nice ;-) jvz.

There's a discussion on the general list about general tools and frameworks. I guess we should jump in there as there is a discussion in progress! > If there was collaboration, I'd prefer it not to be Struts or Turbine based. > A framework where the community at large decides on how the interface > methods are declared would be a powerful thing, and shouldn't be interfered > with because different design methodologies for web applications cause > different projects to exist. I mean, this is open source. There's a services framework in Avalon and there is one in Turbine. I'm all for melding them into a single framework. There's probably good things about both of them, I am only familiar with the Turbine service framework, but I will be looking at the Avalon way soon! jvz.

A little different I think: that was more about velocity related tools, or even webapp related tools, versus general tools like a services framework or db connection pool. I guess it's time for me to jump into the discussion of sharing tools :-) If I can I would like to share an introspector between struts and velocity. I have a feeling that the structs introspector is more complete so I would be all for using the struts introspector and it can probably be done :-) jvz.

There is already a functional services framework in Turbine, is there anyway we could work together on this? jvz.
