Steve, I'm actually very new to this as well. I saw sidebar about MiddleGen in an Ant book and decided to check it out.I spent about a week trying to get things working w/ Jboss and actually gave up on it. I thought I had tried everything, including getting Jboss out of CVS, making the changes to source code (required to get around a known "duplicate column name" issue) and making a custom build, to no avail. I decided to give it another try earlier this week and finally got the sample working. I had some problems getting an ejb from a real schema, but was able to fix it w/ a couple hacks.
As far as I know, the issues mentioned in 1) and 2) are due to current state of the struts plugin. I had to make my own test war file and replace the one that is built and included w/ middlegen-generated ear. In general, I discarted the middlegen struts stuff altogether because it adheres to now seriously outdated version 1.0 of the framework (The 1.1 release candidate 1 is now out). It's still useful as a reference to get started though, if you haven't used struts before. It terms of support, you should be alright. I think that most of the problems I ran into were due to my not really knowing much about EJB/CMP/JBoss. Everyone seems pretty good about responding to questions on the mailing list. As with any open source project, you'll probably have to fiddle around yourself a bit.

Everything generated and deployed without an error. After it deployed, I connected to the generated struts pages. I was able to create person's and flights, but trying to create a reservation had a couple issues: 1) The reservation form did not have fields for person nor flight. Is this a side-effect from our changes? Or is this just the status of the struts plug-in and it exists for all app servers? 2) When I tried to save the reservation I got an Exception stating that CMP is not yet implemented. Again, I do not know if this is just that the struts plugin is still in development, or if the modifications have broken something under the cover. I would be curious to know if you saw the same behavior when you worked with this. I am just starting with Middlegen, so I am still unclear on whether these issues are an indication of how far off the trail I am venturing. Specifically, I am wondering how much support (ie, docs, faq's, mail archives) will be applicable to my setup as I start implementing my own non-sample code. I remain optimistic that I can eventually understand Middlegen and the code it (and xDoclets) produce. Thanks for all your help, Steve B. ----- Original Message ----- From: "Yuri Kouzmov" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, March 13, 2003 4:46 PM Subject: RE: [Middlegen-user] cmp/cmr with jboss > Steve, > > I feel your pain.
