Correct. You can even use the style-sheet from a complete different webserver.

Hi all,

I have two servers. The first server (A) checks the filesystem for new files. If a new file is found a (JMS) message should be send to the second server (B) to do some processing.

Both machines run JBoss 3.2.3 application server.

I just read the JMS tutorial from sun. And read the following:

The PERSISTENT delivery mode, which is the default, instructs the JMS provider to take extra care to ensure that a message is not lost in transit in case of a JMS provider failure. A message sent with this delivery mode is logged to stable storage when it is sent.

Does this mean that when server B (for whatever reason) is down, and server A tries to send a message to B the message is persisted and tried again later?

I have to be absolutely certain that all messages eventualy get to server B, regardless if server B was down for a period of time.

What would be your strategy on implementing this?

i all,
I'm trying to develop a very basic JCA Adapter for Lotus Domino.
I'm using JBoss as my application server. And I want JBoss to pool my connections.
Lotus has a (native) library available which can be used to connect to domino using java.
A basic connection is made as follows:
Session s = NotesFactory.createSession("hostname", "username", "password");
Now I build a JCA adapter so that I can lookup the ConnectionFactory from my (session) beans using JNDI.
Has somebody done something similar? Or does somebody has a basic example for me? I'm realy stuck on this.

Hi all,
I'm thinking of starting teaching J2EE design.
I'm wondering if this is possible. Do I need some kind of certification to teach J2EE? Do I have to pay to use the name 'J2EE'?
I have searched the net about this issue, but I can't figure out what is required to teach J2EE.
Thanks in advance,

Hi all,
I made a J2EE application which uses entity beans. The weblayer uses a session facade session bean which lookups up entity beans and passes the information as value objects.
This works fine.
My ValueObjects also have relations defined.
For example:
Client 1 ---- n Address
In my JSP I can do:
<%
ClientValueObject client = request.getParameter("client");
out.println(client.getAddress().getStreetName());
%>
This also is great. But sometimes I don't need the Address class and just show the Client information in my JSP.
I made the SQL generated visuable in my JBoss console. I was shocked to see that so much SQL was generated.
When large queries are needed this realy slow's down my application.
I looked into the valueObject pattern. And saw that I can make several light-weight value objects, to get specificly needed values. Which causes less SQL beeing generated.
What is a good strategy for passing information between the EJB tier and the WEB tier?
Is it a good strategy to maintain relationships between value objects? Or are the some smarter ways of optimizing?
Thanks!

I think mostlikely you don't have permission to access the method you are trying to call. Look in your deployment descriptor to check the permissions.

Hi all,
I have a J2EE application running in JBoss.
In my application I need some configuration. For instance, we have to email certain recepients when a action occurs. (For instance, when a certain entity bean is removed we have to send an email to a person). In this email we need to have a configurable messagebody, subject, recipients, reply-address etc... etc...
I cannot use the bean environment entries because these only get read at deploy time. I need to be able to change the configuration during run-time.
What would be a good way to make this as configurable as possible?
Thanks for any suggestions!

Yes, it does.

And in my specific case? Because i'm violating the spec, can I break something?

Why should you not use java.io.* in EJB's?
For instance, I have a MessageDrivenBean which does some image processing.
In my JMS message to the bean I include the absolute path to the image file.
Then I do the processing, and save the image.
Is there anything wrong with that? (I'm asking because I have to use the java.io.File class).

I guess you installed JBoss in the 'program files' directory.
You need to install JBoss in a directory containing no spaces at all.
You might consider to try: c:\jboss
Good luck
