Hopeless
Hi all
This is hopeless. I am about to give up, I need small working examples. It
is impossible to guess all difrent configurations needed in all the
deploymentdescriptors. I have no idea about what to read to get an
understanding of this. I have browsed through documentation and read
maililists archives. But nothing seams to bring calrity to this geronimo
CMP mysterium.
I tryed to modify the bank-example but I just cant get it to work.
Please help! Post som small working examples of CMP EJB!

Hi Mattias,
Can you post your configuration files to the user list? Then we can help
you to figure out your problems. We will go with MySQL :-) .
Thanks,
Lasantha Ranaweera

Hi again,
Sorry for last post, I accidently hit ctrl-e trying to write E and that
sends emails in Eudora, the mail client I am using.
Basically, I cant get the deploymentdescriptors right. At least that is
what I think is wrong. If you deploy my EJB.jar only, it deplys fine, but
when I add the war to the EAR deployment fails with a
java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:393)
My application compiles just fine. I am sure this error is caused by errors
in the deployment descriptors.
I'll stop whineing for a while now and give it a new try. This time I will
try using the build in derby database first instead of mysql and see if
that helps. I'll be back...

Hi Mattias,
You may want to look at the source code of the DayTrader application
as it uses some CMP (http://svn.apache.org/repos/asf/geronimo/
daytrader/trunk/). As this application is rather large, you may also
want to have a look at these isolated CMP examples: ejb-jar.xml and
openejb-jar.xml - http://tinyurl.com/k4myx; and CMP sources - http://
tinyurl.com/gga5x.
Also, what are the issues that you are facing?
Thanks,
Gianny

Hi
Yes, momst of my work is based on
http://cwiki.apache.org/GMOxDOC11/ejb-sample-application.html
So far I have bean abel to get a sessionbean working, but CMP EJB seams to
be more difficult.
Lets make a super simple example using a phone-book as an example. A table
like this:
create table phonebook (name varchar(15), number varchar(15));
insert into phonebook values ('Mattias', '1234');
insert into phonebook values ('Jacek','5678');
Now lets make a CMP EJB and a JSP page calling the EJB from where you can
search for names and get numbers back.
If I hade a working example of that, including ejb-jar.xml openejb-jar.xml,
geronimo-application.xml and mysql-pool.xml or what ever other xml-files
needed, I think I could make the rest of my way and go on buld the
applications that I realy whant to do.

I don't have it atm, but would like to prepare something exciting for
the coming JAOO conference in Aarhus in Denmark
(http://www.jaoo.dk/conference/) and your idea seem to be very
appealing. Could you describe what you're looking for? What EAR would
be of interest to you? What configuration would be of help to you?
By the way, have you taken a look at
http://cwiki.apache.org/GMOxDOC11/sample-applications.html?
