I took the exam on September, 14th!!

Tips:

Book: Head First EJB (read twice)
Mocks: from the HFEJB book and EJB Plus
Study an example of Deployment Descriptor: http://www.valoxo.ch/jr/DeploymentDescriptor.pdf
Read the EJB Spec chapter about "Portability: What you should do to guarantee portability" (something like that)

Hi people,

There is a question about ejbCreate() method in page 364 (Mock Exam - Q. 9). The answer in page 369 (Mock Exam - Answer 9) says that the letter B is correct (getEJBObject()). But in page 329 (Creating a new Entity) the new EJB Object is created after ejbCreate() method. So how can I access the EJB Object (getEJBObject method) if it hasn't been created?

The complete question:

Which method(s) from the EntityContext interface can be invoked from within the ejbCreate method?



Thanks
Hello Nicholas,

I am studying chapter 8 from HFEJB and I was trying to do an example of Queue and Topic, but thank you for your suggestion.

Thanks
Hello all,

I have a MDB that listens to a topic. Now I want two MDB to read the same topic. What do I need to add in my ejb-jar.xml? Can I put both in the same xml file? Or in different jar files?


Here is my ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN' 'http://java.sun.com/dtd/ejb-jar_2_0.dtd'>
<ejb-jar>
<display-name>Ejb1</display-name>
<enterprise-beans>
<message-driven>
<ejb-name>MessageTopico</ejb-name>
<ejb-class>com.floripajug.scbcd.MessageBeanTopic</ejb-class>
<transaction-type>Container</transaction-type>
<message-driven-destination>
<destination-type>javax.jms.Topic</destination-type>
</message-driven-destination>
</message-driven>
</enterprise-beans>
</ejb-jar>

Anyone working currently in Australia?
I would like to know more information about IT jobs there, specially Java jobs. Is it easy or there are a lot of people unemployed?

Hello people,

I have passed on SCJP and now I'm studying for SCBCD.
Do you think it's better do the SCWCD first? Or they are independent?

I would like some opinions.

Best regards,

How can I put the parameter "-Djava.security.policy=java.policy" inside my code besides calling it in the command line?
I use: "java -Djava.security.policy=java.policy MyServer"
But I want to do just: "java MyServer"
And then put the "policy" code inside the class MyServer.
Any ideas?
Regards,

SOLVED:
I read in another discussion list about changing the jdk.
I was using the j2sdk1.4.2 from SUN and now I got it from Blackdown (www.blackdown.org) and my server is working !!

When I log into the Portal , in WAS I get the following message:
If you are using CSEnvironment.getEnvironment, you must secure your JSP (in web.xml)!
It seems some portlets added to portal pages cause this error.
Anybody can help me?

Hi all,

Joe,
Thank you for your suggestion.
Im working on a Websphere Portal Project.
To install WebSphere Portal Server 4.2.1 I need to use Web App Server 4.0.5.
Its an IBM restriction.
In my machine I have installed the Portal Server before and this error never happened. NOw, when Im in a machine's costummer I get this error after installing the fixpack. Very weird, doesn't?
I downloaded the fixpack again and now I will try to install.. hope this time it works!
Fernanda.
