RE: Beginner...
To learn to use EJB, it is the SIG (in name) site. If you go to www.northernlight.com, search for EJB tutorial, it is in the first ten sites, and they have a whole section on tutorials. You can also go to www.theserverside.com and download Masterning Enterprise Javabeans. -Original Message- From: Luis Javier Beltran To: Orion-Interest Sent: 2/23/01 8:53 PM Subject: Re: Beginner...

RE: Beginner...
You need to check out the "Orion Primer" at jollem.com. The easiest way to find it is to go to www.orionserver.com , click on "Documentation" and locate the link to it on that page.

Re: Beginner...
Luis, Try the Orion Primer: * http://www.jollem.com/orion-primer/ And perhaps the Orion CMP Primer after that (there's a link from that page). PS: Shouldn't there be a FAQ for this list? -- Ernst Luis Javier Beltran wrote: Thanks to all for your help, but I think I haven't found what I was looking for...

Hello Luis, Friday, February 23, 2001, 10:53:26 PM, you wrote: LJB 1) How can I simply test a JSP? Put it under default-web-app/web directory on a fresh unziped orion distribution. After that, just run orion and point the browser to http://localhost/yourjsppage.jsp It can get a lot more complicated (building apps, etc) but not more difficult. LJB 2) Where can I learn to use EJB?? (Urgent!! : ) ) First, I recommend you the book: Enterprise Javabeans by Richard Monson-Haefel (the O'Reilly book) Also, check out the developer's connection at java.sun.com Hope this help- -- Best regards, Rafaelmailto:[EMAIL PROTECTED]

Beginner: Step by step tutorial?
HI, I am a total beginner to Orion (and somewhat of a beginner to Java). I would be really grateful if some one could point me to a really beginner's step-by-step tutorial on how to write a servlet, to do standard web type stuff like (a) post form variables, and (b) access data from the database (oracle -- is there a way to use OCI directly, instead of JDBC?) Thanks very much in advance, Winnie
RE: Beginner: Step by step tutorial?
http://www.novocode.com/doc/servlet-essentials/ gives a good intro into servlets (though I think the O'Reilly book is better). As to not using JDBC, I don't think so (unless you write your own... which would be reinventing JDBC). JDBC is good, why not use it?

Re: Beginner: Step by step tutorial?
You would always use JDBC. You do have a choice of which driver to use though. If you want to use the OCI native drivers you can specify those in the JDBC datasource. Download the Oracle JDBC drivers from Oracle's site and you can choose between using the Thin or OCI drivers.

RE: Beginner: Step by step tutorial?
May I suggest something... Being that J2EE is already available in most app servers, and the next version is just about to have its specs closed upon, why not move full fledge into a J2EE type of development, where you use JSP pages (instead of Servlets returning HTML in the code (via response)), and if your up to it, use a MVC pattern where you have all requests submitted to a single controller servlet, have that servlet call upon an "action" class, that can then use EJB to perform the logic (or do the logic right there in your action class..until you are up to speed and ready to dive in to EJB). Finally, populate a javabean and forward to a JSP page that uses the javabean to display dynamic content. -Original Message- From: Cory Adams [mailto:[EMAIL PROTECTED]] Sent: Friday, November 03, 2000 8:13 AM To: Orion-Interest Subject: Re: Beginner: Step by step tutorial?

Some beginner questions
Hello all,
I am experimenting with Orion for some days now -- checking out
its features. Must say: Congratulations to the developer team,
very good work already. Some notes and questions, though:
- In the FAQ, there is announced a (GUI?) admin tool for november
(1999, I think..). Is it available somewhere? Looking for such
fundamental things like shutting down the server...
(I know that admin.jar can do that, but I have no success
invoking it correctly...)
- The "hot plugging" feature of Orion is cool -- it works nicely
for all my JSP pages and underlying beans. But it does _not_ work
for my ejbs? When I recompile one of them, I have to kill the
orion server (ctrl-c) and restart it. This can't be true, is it?
BTW: When deploying, orion prints the (xml-)display-name of my web-app,
but NOT the display-name of the ejb-app, here it just says
"Auto-deploying directory... done". Bug or feature?
- In the applications orion-web.xml, I define a classpath where to
look for my jsp-beans (../beans). For some funny reasons, Orion
copies the .class files of my ejbs into this directory when
deploying. So, I have two locations for them (my app is named ic,
the ejbs are in package staff):
ic/ic-web/beans/staff/foo-ejb.class
ic/ic-ejb/staff/foo-ejb.class
Bug of feature?
That's for now, thank you for your help,
Greetings,
Benjamin Lorenz
