Hello,
Two days ago I started looking into jBoss.
I have downloaded and installed the jBoss 2.0 FINAL with Tomcat support.
Problem is I still have not been able to access any EJB's in the server.
There are lots of documentation on how to make EJB's, how to deploy them,
how to access them via JSP etc.,
and the mailing list archive also is a rich source for a beginner.
But I have not been able to find a simple, straightforward, complete
example that can be downloaded, installed, and run.
Does anybody have such an example that can be deployed under Windows 2000,
and run without changes against a jBoss server running on localhost?
If such an example exists, and if it in addition includes a CMP Entity Bean
that uses an Oracle database for persistence, and both a standalone
testclient, and a JSP testpage, then it would be greatly appreciated. (if
not, I will be glad publish it here as soon as I have figured out how to do
it. But it may take some time...)
The examples on jboss.org are fine, but more guidelines than complete
examples, and suited for a non-windows environment.
(If you as a beginner has to do things manually, you tend to think that
every error you get has do do with your own lack of understanding. That's
why a simple yet complete example would be wonderful.)
I have tried the testsuite for jBoss, but could not build it without making
modifications to the build.xml (different ant versions?).
Deploying the testsuite jar-files causes messages like
[Verifier]
Bean : Teller
Method : public abstract Teller create() throws RemoteException
Section: 6.10.6
Warning: The throws clause of a create(...) method must include the
javax.ejb.CreateException.
Trying to run eg. dbtest.bat gives this error:
Welcome to the database test

Could not lookup the context: the beans are probably not deployed
Check the server trace for details
java.lang.Exception
at org.jboss.test.dbtest.test.Main.testAllTypesBean(Main.java:99)
at org.jboss.test.dbtest.test.Main.main(Main.java:42)
(I included a printStackTrace to get the information above).
I did not find the class in question when searching the jBoss inst. dir,
and server trace says nothing (if this refers to
the output in the dos window where jBoss is started).
Hope somebody can help, because I really should like to be able to move
ahead (preferrably with jBoss) soon....
Regards,
erik
