Hello Hibernate -

page 80, first paragraph:


As a neophyte I'm not sure how to interpret this instruction practically.
My best guess is to copy only those files from the ~\server\default\conf
directory and no others. Is this correct?

If this assumption is correct, should the conf directory structure be
stripped out with files in subdirectories, eg
~\props\jbossws-roles.properties, insterted directly in ~\src, or
should the server conf directory contents be copied in verbatum?

Also, WORKDIR and JBoss server dir both have a jndi.properties
file. The value for the java.naming.factory.initial property
differs between the two with the WORKDIR version value set
to org.jnp.interfaces.LocalOnlyContextFactory and the
JBoss server version set to org.jnp.interfaces.NamingContextFactory,
additionally cautioning


I dont know what I am doing. How should this potential conflict be handled,
eg should the server version be copied into the WORKDIR space, or ?

Please advise.

Please read the chapter again. It does not say: "Install JBoss Application Server". It says "Install the embeddable server for EJB3". See this thread:

http://forum.hibernate.org/viewtopic.php?t=972608

Just download the working code with all server software included from http://caveatemptor.hibernate.org

Thank you.

Still on helloworld-ejb3, using unedited helloworld-ejb3 install files.
Downloaded and unzipped jboss-EJB_3.0_RC1.zip.
Copied all files across to WORKDIR lib & src. Compiles ok. db startup ok.

run yields:



file embedded-jboss-beans.xml mentioned on page 84 not in
EJB_3.0_RC1.

Do NOT download anything else but the helloworld example package. It has everything you need. Just unpack it. You do NOT have to install anything else. Follow the README.

OK. followed readme. same result (jdk1.6.0). so rebuilt my lab rat machine from scratch, wipe disk, winxp re-install etc.

installed these packages:
jdk1.5.0_11
apache-ant-1.6.5
hsqldb_1_8_0_7
hibernate-3.2.2.ga
jpwh-gettingstarted-061110

no edting/alterations.

result:

You do NOT have to install any libraries. I wonder why I can't get this through. JDK 5.0, Ant ready, unzip the archive, run it.

Oops, sorry.

hsqldb_1_8_0_7 and hibernate-3.2.2.ga arent installed as in
included in path or classpath only downloaded (in case I
got to the point where debugging and src would be useful).
I'll remove them altogether then and have another go.

Same result with only ant, java5 installed. What information can I
supply to help resolve this issue?

You could use the last version, which has been online for three months:

Oh sorry, this is not the Getting Started. I will check that again too...

It's a Microsoft Windows issue. Until I release a one-line fix for the braindead Windows path separator, read the comments in HelloWorld.java and replace the FAST scanning method with the SLOW scanning method by commenting/uncommenting the appropriate lines.

Please try this for me on Windows:

Thanks, I'll give it a go.

I had the same problem. And found 2 possible causes:

1)
I noticed that the problem did not occure when using the ANT build file provided in the examples, but did occur when running it manually from Eclipse without ANT.
When the ANT java task attribute

is removed from the build file, the problem does occur.
Ant doc about the fork attribute: "if enabled triggers the class execution in another VM (disabled by default)".

2)
If I run it from the command line (outside Eclipse), I have to use the full absolute classpath. For example, this will fail (NameNotFoundException):
(Current directory is c:\java\build)

and this will succeed:



The EJB3StandaloneBootstrap.scanClasspath() method in the main method of HelloWorld must also be set correctly.
In my case it will succeed when using:
(Current directory is c:\java\build\)

(Which is a bit strange because I'm already in the "build" dir. Specifing it again makes no sense to me, but without it, it will fail.)
but fails when using the absolute path something like:


Also note that the jboss docs say:


---

Edit:
the most simple solution:
You can simply change the scanclasspath to:


Then you don't have to use the "fork" attribute; Eclipse and other IDE's can run it directly; and command line doesn't require the absolute path, so that this will also work:
