Only drawback IMO with Netbeans is lack of various server support like Eclipse. Yes, you see it in the NB user group as well... people running more than one IDE... ie they just there to get at swing tools, or VWP, but they got their JBOSS or whatever running in Eclipse, or something else. I think running more than one IDE is now just a fact of life... and there are two definite camps... you want swing, you go NB, you want to dev on Android, it only works well in Eclipse... its more about allegiances than technology, who's making what, and what tool are they into. GlassFish is NB... most of the others are Eclipse... TC is pleasantly neutral... NB is good with TC, but works a little diff to Eclipse... When it comes to dB tools on the web, I still do it the old way... make the site in an HTML editor, do the JSP and use JDBC for the dB... the first time is difficult, learning the MVC model in TC... after that I think its much faster... just check out VWP carefully... its a very heavy application of JSF.. and for a large site, it gets slow, very slow. We use VWP, but we cannibalize it... ie if we need a tree in a web page, we use the wizards... then open up the source and just extract the CSS, and script ;) How you use Java tools, is as much a skill as just learning the langauge itself... I think ;) NB 5.5 is a better product for TC dev, than NB 6 is... NB 6 is still very very buggy... its got a little too fishy for my liking ;) Why we only use TC and have put a tremendous amount of investment into it its a no nonsense light weight container... it does what it does very very well. Master of the WEB and people understand it... as apposed to jack of all trades, master of none... there is very little you cant make TC do... the way we run TC, eats fish for breakfast ;) Have fun... --- HARBOR : http://www.kewlstuff.co.za/index.htm The most powerful application server on earth.

From: Tommy Pham [mailto:[EMAIL PROTECTED] Subject: Tomcat 6.0.18 JavaEE 5/EJB3.0 I think it's because of the javaee.jar causing conflict with tomcat's jar files. Correct; you don't want to have javaee.jar (or its predecessor, j2ee.jar) anywhere near Tomcat. You can try to extract the necessary packages from javaee.jar and place them in Tomcat's lib directory.

The only J2EE Container that I know uses a pure version of Tomcat is Geronimo (but, while not having looked, I understand that the changes in JBoss are pretty minor). I agree with Chuck that you shouldn't include a full J2EE jar (any vendor) with Tomcat, and often times the easiest is to just include the pieces you need. But I'm guessing that it will be easier for you to just pick a J2EE vendor.
