Sorry to hear that you are frustrated with it. The most important thing to change is
still the configuration name tag:
<configuration-name>Default Stateless Session Bean</configuration-name>
That has to match a container configuration that is either defined in jboss.xml _or_
standardjboss.xml. standardjboss.xml has the following containers defined:
Standard CMP EntityBean
jdk1.2.2 CMP EntityBean
Standard Stateless SessionBean
jdk1.2.2 Stateless SessionBean
Standard Stateful SessionBean
jdk1.2.2 Stateful SessionBean
Standard BMP EntityBean
jdk1.2.2 BMP EntityBean
There is no Default Stateless Session Bean container defined. I am guess that the
most appropriate one for you is Standard Stateless SessionBean. Change the
configuration name in your jboss.xml file to and let me know what you get:
<configuration-name>Standard Stateless SessionBean</configuration-name>
I hope that you don't mind my copying jboss-user in case I am wrong about
standardjboss.xml or something...

Subject: [jBoss-User] Minerva - I dont get the problem - please help
Hi Jeremiah,
well.. thanks Jeremiah - I followed your procedures and I'm close to giving
up, because I get the same output returned.
I deleted the res-ref lines out of ejb-jar.xml, I only have res-refs in
jboss.xml now.
And still this nullpointer exception when deploying Quiz.jar
I m posting this a last time to the group now.
Here are all the files, whoever wants to check it out and reproduce is
invited to.
Perhaps there is just some spelling error, perhaps its not "Default
Stateless SessionBean" but
"Default Stateless Session Bean" or whatever.
Ciao, Jubin

?)

And here the code fragment executing the db lookup, but in fact, this is
never called, since I get the NullPointerException at Deploy time :
public QuizPattern getQuizPattern(int level) throws SQLException,
javax.naming.NamingException
{
/* lots of declarations cutted */
try {
/* try to get a connection from the database pool
named postgres */
naming = new InitialContext();
ds =
(DataSource)naming.lookup("java:comp/env/wapdb");
con = ds.getConnection();
st = con.createStatement();
/* get the count of interesting records */
rs=st.executeQuery("SELECT COUNT(question) FROM
wapquizview WHERE (difficulty = " + level +");");
/* stuff cutted again */
}
