hi, At about $800.00 AUD (roughly=$395.00 USD) I'd forget all about idea ... what about some ide's with sensible prices? I realised JBuilder was a waste of time after using it for years, and waking up to the fact that I only used it to package classes anyway. I bet people who are recommending idea are using other people's money to buy idea licenses?

Need to be metioned that Forte based on open source NetBeans. Take a look to JDeveloper from ORACLE also.

RE: Concurrent calls to Session bean methods
Hello All,
Thanks very much for all the help you have provided for this query.
I looked into the Java pet store class which you had referred me to.
And have also implemented a facade class.
Here is an example of what our application looks like.
There is an MDB called MyMDB, a stateful session bean called
MyStatefulSessionBean and a facade class called MyFacade
MyMDB.java
---
public class MyMDB extends java.lang.Object implements
javax.ejb.MessageDrivenBean, javax.jms.MessageListener {
static m_myFacade;
private _createFacade()
{
// Creates Facade class
// Initializes myStatefulSessionBean variable in the Facade class
}
public void onMessage(javax.jms.Message message)
{
if( message is init_message )
{
_createFacade();
}
m_myFacade.processMessage( message );
}
}
MyStatefulSessionBean.java
---
public class MyStatefulSessionBean extends java.lang.Object implements
javax.ejb.SessionBean
{
public void processMessage( Message message );
}
MyFacade.java
-
public class MyFacade extends Object
{
MyStatefulSessionBean m_myStatefulSessionBean;
public synchronized void processMessage( Message message )
{
myStatefulSessionBean.processMessage();
}
}
But when the application runs, and sends an init message to MyQueue ( with
which the MDB is accociated ), the onMessage() of MDB gets called. And the
processMessage() gets called and facade class is initialized. The system
behaves in the way it is expected to.
Then, if MyQueue recieves another message, the system still beahves fine by
calling processMessage().
The problem occurs if MyQueue gets more than one messages ( from more than
one threads ). The control comes into onMessage() everytime. Unfortunately,
m_myFacade.processMessage( message ) doesn't get in all the cases. I don't
know if this is a problem with synchronization or may be I am doing
something wrong here. Please somebody help.
Thanks,
Vani

Petstore Problems
Hi I am new to orion I just installed version orion1.5.4 and I am in the process of trying out the examples. I was able to follow the taglib-tutorial, and the atm example. I am having problems setting up the petstore example. I followed the instructions according to the estore-install.txt file. After installation and going to the web address : http://localhost/petstore/ I am able to get the main page to display fine. Once I enter the store to the address http://localhost/petstore/control/main I get the following error and message: Error: The User ID you selected is already in use. Please go back to the previous screen using the 'Back' button on your browser and select a different User ID. Any idea what I am doing wrong? Thanks __ Do You Yahoo!? Yahoo!

RE: Java IDE?
I'm fond of Forte from Sun, but it needs plenty of memory and processor to run. The two really nice things about it is that it is freely available (Community Edition, anyway) and that it is from Sun, the owners of Java. Don't take the system requirements lightly.

What do you mean outside of the application? The database is
populated with some base data before the application can start
doing anything.

Here's my new data-sources.xml (snip):
My orion-ejb-jar.xml has this entity-deployment node:
That's for an entity bean for the database table
"PrimaryKeyGenerationTbl", where a mapping of table name to
max(prikey) is stored for every other table in the database.
Here's the piece of code that throws the
ObjectNotFoundException:
public Long getNextNumberInSequence(String tableName) throws
PrimaryKeyGenerationException, RemoteException {
Long key = null;
Primarykeygeneration pkgRemote =
(Primarykeygeneration) hmpEntries.get(tableName);
if (pkgRemote == null) {
// add an entry to the PrimaryKeyGenerationTbl table
try{
pkgRemote = pkgHome.findByPrimaryKey(tableName);
} catch(javax.ejb.FinderException e) { // this exception
throw new PrimaryKeyGenerationException(msgId1, e);
}
hmpEntries.put(tableName, pkgRemote);
}
// ... and so on and so forth
}

Thanks a lot. That solved my problem. I have another problem though. When I deploy my own app into orion, the cmp beans get deployed properly (w/o any error messages).

[ann] WebWork 1.0 released!
I'm proud to announce the release of WebWork 1.0! WebWork is a HMVC web application framework in Java, developed as Open Source (BSD license) and designed to help create dynamic websites using minimal effort and maximum flexibility. It's architecture is easy to learn and understand, yet has features that allow for complex applications to be built. One of the main features is it's total separation between the controller and view aspects of an application, thus allowing for a multitude of view technologies to be utilized. Out of the box WebWork has support for JSP (and comes with an extensive tag library that covers most needs), XSLT, and the template engine Velocity. Adding support for more such tools is very easy (the Velocity "integration" was done in hours), allowing you to have maximum flexibility with regard to how you structure your application. You also get to choose whether you want to use a Model-1 or Model-2 approach to building applications, although we'd recommend using both as is described in our comprehensive documentation that includes reference sheets (for the tag library and expression language) and many useful tips&tricks sections. WebWork comes with a comprehensive set of examples that are both used to test the functionality of the framework, as well as showcase how it can be used. Many examples are conversions from other frameworks (such as Struts) so that you can see firsthand how WebWork differs from the rest of the crowd. One of the most important tasks when working with frameworks like this is the configuration step, which is where Java classes are mapped to logical names (used for invocation) and where the connection between controller and view (such as a JSP or Velocity template) is made. This configuration can be done manually, but to ease this process there is an XDoclet extension available (through the XDoclet project, see http://xdoclet.sourceforge.net) that will allow you to specify all such configuration directly in your Java code using custom WebWork-specific JavaDoc tags. XDoclet is also used to generate HTML documentation of your application, which helps to serve as a communication channel between the Java developer and web designer (if those roles are separated into several team members). There are a multitude of other unique and interesting features that we are very excited about, but we'd encourage you to download and find out about those yourself. So get it now from: http://sourceforge.net/project/showfiles.php?group_id=14797 Documentation can be found in the download, or online at: http://213.203.18.31/ We encourage you to try WebWork together with the wonderful SiteMesh (http://www.opensymphony.com) and XDoclet tools, a combination which can give you an amazing productivity and clean application architeture. This is an OpenSource project, developed using an open development process, and is hosted by SourceForge. If you have any questions we recommend the user mailing list, and if you have suggestions for improvements we're all ears on the development mailing list, both of which can be found on the project homepage at: http://sourceforge.net/projects/webwork If you are attending JavaOne this year, then you might want to stop by our WebWork developer meeting on Wednesday March 27, 6.30pm at Fourth street Bar & Deli (across from the Metreon).
