The online editing for the CMS is still a bit unfriendly. Hoping to put my Infra hat on and hack on it again at some point. Anyway, the 'submit' button really just saves and your edit is still in your private sandbox. Click the edit link on the page again then tack on "?action=mail" and then it will send off the patch. The url would look something like: https://cms.apache.org/openejb/wc/diff/dblevins-_Le_Oo/trunk/content/unix-daemon.mdtext?action=mail The link is only available once you've saved an edit and are presented with the 'successful edit' page, at which point you have to know to click 'Diff' then on the next page click 'Mail Diff'. It's a work in progress :) -David - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: using static helper classes within servlets
That's too bad. A workable solution in EJB 2.1 would be to use a
stateless bean and set the pool size to 1. That will effectively give
you a singleton, though keep in mind it won't be multithreaded so code
appropriately.

Hey all,
If the goal is to ensure that only one instance is in the webapp,
I'd recommend the new EJB 3.1 bean type @Singleton which is
supported in OpenEJB 3.1 and 3.1.1.
http://openejb.apache.org/3.0/singleton-example.html
http://openejb.apache.org/singleton-ejb.html
Instantiation can be done at startup or lazily. All method access
synchronization is handled for you via
@ConcurrencyManagement(CONTAINER) or by you
@ConcurrencyManagement(BEAN). Regardless of that choice we will
still handle sychronization of instantiation, so double-check-
locking or other things will not be necessary.

I've not done anything with EJBs and I'm not sure what exactly you
mean by
static "properties". I have however dealt with reducing
instantiations in
servlets. I simply created a BeanBag class with static methods to
each one
of my beans; these are not "proper" beans, but where simply
objects that
were formerly used in JSP via the jsp:useBean directive.
Here is the general pattern:
class BeanBag {
private static SomeBean someBean = null;
public static synchronized getSomeBean() {
if (someBean == null) someBean = new SomeBean();
return someBean;
}
}
I have now numerous Servlets, JSPs and POJOs that use BeanBag to
obtain
singleton instances of my beans. Its worked great for me.

Re: how to integrate tomcat with open EJB for online money transactions
I have to agree with the financial transaction advice. Should you need it for other things, the steps for integrating Tomcat and OpenEJB are pretty simple: 1. Download and unpack Tomcat (any 5.5.x or 6.0.x) 2. Download the latest openejb.war file and place it into the webapps/ directory. 3. Start Tomcat You can optionally go the "http://localhost/openejb/"; page and run through the installer after step 3 which will install a javaagent (only really needed when using OpenJPA on Java 1.5). -David On Mar 6, 2009, at 11:20 AM, Rusty Wright wrote: Go back and read my note to your previous post where I refer to CyberSource's Hosted Order Page (HOP) and credit card industry's PCI security requirements.

It is a decent product and provides a good interface between the Java obj's and the beans. You simply write your beans and your sql, run a tool of theirs on this, and it creates a bean jar and configuration file with the sql embedded in it. Thanks for the comments, Maurice. Just to add a note on this thread. The Tomcat/OpenEJB integration now runs in three modes. The first two are as you mentioned: OpenEJB beside Tomcat in a separate VM; OpenEJB embedded into Tomcat and available to all webapps. The new third style is OpenEJB embedded into a *webapp* and available only to that webapp -- each webapp can have it's own private ejb container. The webapp can even have remote ejb clients that communicate with it's ejbs over HTTP. With this style, you don't even have to have a separate ejb archive -- you just add a META-INF/ejb-jar.xml file to your webapp and you're done. That's pretty much my preferred integration style now.
