Since I am starting studying EJB3 now....so I didn't know what to expect.
Although I was expecting an Object of my bean type, someone in another forum explained to me that EJB returns a proxy for the object.

Now I would like to know how to use a local interface, could you please help me?
Is it possible (and a good practice) to use a local interface in the client?

best regards
Hello all!

I need some help with the following:

Web Server - Jboss 5.1.0 GA
IDE - eclipse

I created a EJB project using eclipse and the following files:

ejb.server.HelloWorld.HelloWorldBeanRemote


ejb.server.HelloWorld.HelloWorldBeanLocal



ejb.server.HelloWorld.HelloWorldBean



and the client



I execute the project from Eclipse and my ejb is deployed as I get the message:
11:27:41,999 INFO [EJBContainer] STARTED EJB: ejb.server.HelloWorld.HelloWorldBean ejbName: HelloWorldBean
11:27:42,018 INFO [JndiSessionRegistrarBase] Binding the following Entries in Global JNDI:

HelloWorldBean/remote - EJB3.x Default Remote Business Interface
HelloWorldBean/remote-ejb.server.HelloWorld.HelloWorldBeanRemote - EJB3.x Remote Business Interface
HelloWorldBean/local - EJB3.x Default Local Business Interface
HelloWorldBean/local-ejb.server.HelloWorld.HelloWorldBeanLocal - EJB3.x Local Business Interface




When I run the client as a JAVA APPLICATION I get the output:
Proxy to jboss.j2ee:jar=EJB.jar,name=HelloWorldBean,service=EJB3 implementing [interface ejb.server.HelloWorld.HelloWorldBeanRemote]
Proxy to jboss.j2ee:jar=EJB.jar,name=HelloWorldBean,service=EJB3 implementing [interface ejb.server.HelloWorld.HelloWorldBeanRemote]
Proxy to jboss.j2ee:jar=EJB.jar,name=HelloWorldBean,service=EJB3 implementing [interface ejb.server.HelloWorld.HelloWorldBeanRemote]

What I am doing wrong that I dont get the object I want from the Container?

Hello all ranchers,

I would like to share with you that i passed the scwcd 5 exam with 86%.

I read the notes on the j2ee patterns from Peabody(thanks, i got 83% on patterns) and ready HF second edition 3-4 times and used jwebplus as my mock. Didnt liked the final book mock exam...

I got 39 correct answers on the final mock exam and the 20 points rule did not applied to me (thanks God), it only served to destroy my confidence....on the other hand...jwebplus was really helpfull to understand concepts and to learn api,etc.

Thank you all for answering my last time questinos...

best regards to all

Does it happen in the first client request or it can happen at deploy time?
What the specs say about it?

regards
Even if the expression was inside the for tag it would not compile. Expressions doesnt have access to the tag vars.

correct me if im wrong.

Is the filter obligated to call chain.doFilter(req,resp)?
Thank you Deepak Jain!

Option C is marked as beeing the correct answer. I disagree. I think D is the correct answer.

Can someone confirm it please?

regards

This is wrong. You have to add <%@ page errorPage="arException.jsp" %> in the
index.jsp

index.jsp



arException.jsp




tException.jsp



The book says: Declaring a catch-all error page
This applies to everything in your web app´┐Żnot just JSPs. You can override it in individual JSPs by adding a page directive with an errorPage attribute.

If you override it, it works.

Why is 19.5 wrong?



I think the 19.5 means that the web.xml does not define *where* phisically your deployment should happen. It defines the configuration of your web app and not the deployment itself.

yup...

But i remember seeing a question using something like <%= ${movieList[i]} %> in JWebPlus saying the i var was only visible inside the scripts.... I tried this approuch and couldnt make it work.

I have the following code:




Is it possible to make this work?
