Re: JTA support
Freddy, IMHO your options in this issue are: 1. Use Tyrex (Dead project, so you're on your own when you run into problems) 2. Use JOTM from Objectweb (that code is not really maintained nor in a good shape either. current project lead agreed on the mailing list, that it's probably a good idea to rewrite and several people who have run into problems have come to the same conclusion) 3. Use JBoss (Almost certainly the best-supported but that means you have to learn how to set up tomcat to run within JBoss, the complexity of which others should judge as I have not tried it) 4. Buy a commercial solution as the one by atomikos (rather strange licensing model IMHO) The right choice depends on what kind of project you do (critical commercial or less critical e.g. university project). I would recommend against 1 which I've been doing myself and it's not really worth the trouble. 2 is rather easy to set up and OK if it works for you (as I mentioned quite a few people including myself have run into some issues but a lot of others as I understand use it in production with success). I guess 3 would probably be the safest route but might be a bit of a learning curve in the beginning. 4 I have not used but if you don't know exactly how many concurrent TXs you will have the license may become very expensive.

RE: JTA support
Thanks, Robert. You've been quite helpful! In Fact, I'd already installed and configured JBoss, knowing that it was the best (cheapest / safest / easiest) option available; that is, those I could envision based on my knowledge / experience, of course -- for instance, I didn't know products such as JOTM (therefore, did not took it into account as a possibility). Based on your comments and my previous thoughts about this issue, I believe I'll just stick to JBoss, play it safe. Should anybody else have a different opinion, I'm still open to suggestions.

Re: JTA support
Hi Freddy, do you know (or anyone else for that matter) where to find instructions how to configure a minimal JBoss to provide Tomcat 5 with JTA? On the JBoss website I can only see bundles with Tomcat 4. In case you succeed. I would be interested in having a look at your configuration files.

RE: JTA support
Hi Robert, Well... eerrrhmmm... let's see: I just downloaded JBoss' latest version. I has already integrated (ready to use) Tomcat 4 (v4.1, if I recall). Then, based on what JBoss claims, I suppose (have not confirmed it, I have to say...) that the JTA management implementation is provided (as specified by Sun's JTA specs) by JBoss. The complementary part is, as you already know, provided (or not) by the JDBC driver you are using. In a few words, I'm trusting JBoss's JTA-ability, not Tomcat's. That said, I can do this for you: (1) Given the fact that I'll be using JBoss + Tomcat 4, just as they are shipped, I'll develop a few JTA test over JBoss. Once I run them all, I can send you my config files (cannot guarantee when I'll finish this, I'm into lots of stuff right now). :) (2) I can give it a look to see if I find something on the Internet (so far, all I've found refers to v4, not v5). Let me know if there is something else I can do for you.

RE: JTA support
Hi, Sorry if I misled you. I'm using JBoss v3.2.3. According to that version's download page: (includes Tomcat 4.1.29 JBossWeb HTTP server and JSP/Servlet engine, EJB, CMP2.0, JCA, IIOP, Clustering, JTA, JMX and more) I suppose (would have to start it up and check the logger's output) that's the default version used by that version of JBoss. However, I can't assure anything about other versions (of JBoss).

You are right, Nik. There it is. However, I believe the default used by JBoss (as shipped, of course) will be v4.1.29... right?

In any case, even 3.2.3 had both branches, only 4.1 was the default. Nix. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
