RE: EJB in tomcat
EJB needs EJB container. Tomcat is a servlet/jsp container. However, you can find enterprice beans through naming lookup. -Original Message- From: Mark Thomas [mailto:[EMAIL PROTECTED] Sent: November 29, 2004 2:55 PM To: 'Tomcat Users List' Subject: RE: EJB in tomcat Can EJB's be deployed in tomcat ??

RE: EJB in tomcat
Anson, The one I've used for over a year and a half is OpenEJB. It's an EJB container and is 100% pluggable into Tomcat. Here is the url: http://openejb.sourceforge.net If you need any help, let me know.

Re: EJB in tomcat
there are plenty of open source EJB containers, Tomcat is not one of them. www.jboss.org has been a popular choice Filip - Original Message - From: zeallousbigpond.net.au [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, September 08, 2003 5:17 PM Subject: EJB in tomcat hi, I would like to ask, can Tomcat work with Enterprise Javabeans?

Re: EJB in tomcat
Well, Tomcat needs to 'colloquiate' with an application server (where EJBs
are deployed). The answer is yes, it's possible; all your application needs
to do is to establish a context with an application server and then it can
use the component deployed on application server generally using a lookup.
Here follow a snippet from a code:
InitialContext context = null;
//getJbossContext() sets up the correct property file and returns a context
initialized to that property file
context = getJbossContext();
Object node = context.lookup(sessionName);
PeopleDbManagerHome home =
(PeopleDbManagerHome)PortableRemoteObject.narrow(node,
PeopleDbManagerHome.class);
bean = home.create();
} catch (RemoteException e) {
printRemoteExceptionMessage();
return null;
}
Hope it will help,
Marco

hi,
I would like to ask, can Tomcat work with Enterprise
Javabeans? 'cause I read from the Java site...it says that we need a
BEA server? Is it necessary? Or tomcat it self already has those

RE: EJB from Tomcat
Having never used the jboss tomcat bundle, I wouldn't be able to say. It is very different though. One thing different about this integration is that it isn't a bundle, it's the ability to add EJB functionality into any Tomcat version you want via a plug-in. Which means you don't have to convince anyone to switch platforms, etc. You can just plug in OpenEJB and try it out for a while, if you don't like it, just unplug it. No harm done. -David -Original Message- From: Andy Richards [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 13, 2003 9:05 AM To: Tomcat Users List Subject: Re: EJB from Tomcat Is this easier than using the jboss tomcat bundle? i will read the article when i get a chance andy On Thu, 2003-02-13 at 14:54, David Blevins wrote: All, I wrote some time ago about the Tomcat/OpenEJB integration, which allows Tomcat users to start using EJBs from Tomcat without having to ditch your Tomcat installation and configuration.

RE: EJB from Tomcat
Right, this is an EJB container that is usable in Tomcat. The particularly neat thing is that the EJB container can run embedded *inside* the same VM as Tomcat. You can even configure OpenEJB to not marshal calls to EJBs, basically treating your remote interfaces as EJB 2.0 Local interfaces. In the end you get a single server that can run both servlets/jsp/ejb together in the same VM with local optimizations. -David -Original Message- From: Will Hartung [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 13, 2003 11:33 AM To: Tomcat Users List Subject: Re: EJB from Tomcat From: David Blevins [EMAIL PROTECTED] Sent: Thursday, February 13, 2003 6:54 AM Subject: EJB from Tomcat All, I wrote some time ago about the Tomcat/OpenEJB integration, which allows Tomcat users to start using EJBs from Tomcat without having to ditch your Tomcat installation and configuration.
