Tutorial

[sophie.dog]

For any JBoss newbie who, like me, has given up with the Getting Started / Quck Start documentation:

http://www.dsg.cs.tcd.ie/~dowlingj/teaching/ds/tutorials/ejb/jboss_3_intro.htm

This is a very simple tutorial, just to get your first Session bean up and running. It works with JBoss 3.2.1.

Thanks a lot Sophie

First off, thanks for the tutorial!

Now, as to my problem...

I am trying to use this tutorial using JBoss 4.0. I got to the point (with a minor tweak to the tutorial here and there) of running the client, but when I do this:

java ie.tcd.cs.ejb_example.HelloWorldClient

I get this:

C:\jboss-4.0.0DR2\Projects\Hello>java ie.tcd.cs.ejb_example.HelloWorldClient
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interf
aces.NamingContextFactory. Root exception is java.lang.ClassNotFoundException:

at ie.tcd.cs.ejb_example.HelloWorldClient.main(HelloWorldClient.java:21)

Exception: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory


Here is what my classpath looks like (just in case it is helpful in solving this):

.;C:\Program Files\Altova\xmlspy\XMLSpyInterface.jar;%JAVA_HOME%\jre\lib;%ANT_HOME%\lib\ant.jar;%JBOSS_HOME%\server\all\lib\jboss-j2ee.jar;%JBOSS_HOME%\log4j.jar;%JBOSS_HOME%\jboss-common-client.jar;%JBOSS_HOME%\jboss-system-client.jar;%JBOSS_HOME%\jnp-client.jar;%JBOSS_HOME%\jboss-client.jar;%JBOSS_HOME%\jbosssx-client.jar;%JBOSS_HOME%\Projects\Hello\HelloWorld.jar

Any ideas?

Thanks!

[gavin9]

worked for me with the following two jars in my classpath:
$JBOSS_HOME/client/jbossall-client.jar
$JBOSS_HOME/server/default/lib/jboss-j2ee.jar

I have experienced problems with environment settings on Win2K & XP. Maybe put your jars in a dir with no spaces?

[darrinps]

That didn't do it, but I appreciate the effort.

I think I'll try creating an application descriptor and see if that will work.

Very frustrating...

[darrinps]

Spoke too soon!

I had a typo in my classpath.

Now I get the initialcontext but I still get an error and this one I cannot find anywhere on the Internet.

Anyone know why I might get this?

sophie,

I downloaded jboss-3.2.1_tomcat-4.1.24
I am running jdk1.4.1_03

i ran run.bat and got :
...
20:03:51,403 INFO [Server] JBoss (MX MicroKernel) [3.2.1 (build: CVSTag=JBoss_3_2_1 date=200305041533)] Started in 30s:163ms

But I don't get anything at http://localhost:8082/

I do get a response from Tomcat when I try:

http://localhost:8080 -
HTTP Status 500 - No Context configured to process
this request
...
Apache Tomcat/4.1.24-LE-jdk14

>> So Tomcat is up

Of these the only jar file I was able to find was the
log4j.jar in the ...\server\default\lib dir


>>> Any thoughts on how I could get past this
would be great

Thanks,
Manco

Sophie,

The Distributed Systems: Introduction to JBoss
needs one modification. To bring up the Agent View
the user needs to point to :

http://<machine-name-or-ip-address>:8080/jmx-console
If you are running JBoss in a single PC - http://localhost:8080/jmx-console

NOT http://localhost:8082 as the doc suggests.

I am on to the next step.

Thanks,
manco

PS: I got this from :

[sophie.dog]

To give credit where it is due, I didn't write the tutorial,
I simply found it on the net. It was written by Jim Dowling at the University of Dublin in Ireland.

[vvp]

MasteringEJB2.pdf is even better, very clear and well written.

Can be found for example in:
http://coweb.cc.gatech.edu/squeakers/10

[camale]

sophie.dog,Thank you very much!

I am a newer in EJB,and I looked for JBoss Doc for servral days,So Thank you very much again.

[ejbnewbie]

Hi everyone-
i have one more tutorial in JBoss-3.2.1 w/ Oracle 9i, not much, just a simple one-one Entity Bean relationship, with stateless Session Beans, JSPs, Webworks. the link to the thread is
http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= you find it useful

peace

[johnybravo2004]

how do i set the CATALINA_HOME for the built in Tomat within JBoss
is it C:\jboss\server\default\deploy\jbossweb-tomcat55.sar

[sujeet.banerjee]

@johnybravo2004

Well, you dont need to set the CATALINA_HOME.

Make sure that your JBOSS_HOME and JAVA_HOME are set correctly.
