I am doing my first steps with JBoss (3.2.3) and CMP (2.0).
wondering about the poor performance of my finder methods
I took a look into the SQL that went to the database.
"SELECT DISTINCT OBJECT(p) FROM Person p"

We've been troubling for some time now with implementing a many-to-many
relation using CMP. We are using JBoss 3.0.8, Eclipse and XDoclet.
So, we have the following two tables:
User 1 -------- * Friend * ---------- 1 User

A *beginners* question.
I make use of Netbeans IDE 3.5.1
I'd like to make some application which is able to send mail.
So I found out that the API "javamail" might be useful.

Hi everbody,
It's possible to have some code to illustarte your solutions ?
Thank you all

I've following problem. The project I'm working in has two main
functionalities: first is gathering data, and the second is data
processing.
First one is implemented as EJB. There are mainly only simple CRUD

I am beginner in Java and JavaBeans. Now I have problem (I have a lot of
docs and books, but can't understand how to resolve my problem). (Sorry for
my English).
1-st class is descendant of  Object (no Component!), it is non-visible bean

On the internet several tutorials are available on Java.
But I'm still looking for a nice tutorial on JavaBeans.
has anyone a good suggestion for me
thanks in advance.

I would like to create a custom number identifier for a CMP bean. I would
like just work with a sequencial number begining to 1 an step by 1.
How can I do implement that ? I would like also when the EJB server crashes,
thant this sequence is automoticaly set to the max number + 1.

I built an EAR (on WebLogic) that contains 2 session EJB which share
some common Java classes (utility methods for example).
I made a .jar with the .class of the common classes and I put it in
directory META-INF/lib of the EAR.

I am new to JSP and was wondering if there is a way to call a
javascript function inside the setproperty value.  like the following
<jsp:setProperty name="converter" property="startTime"
value="randomFunc()" />

From this EJB book I am reading (Richard Monson-Haefel) it says that
all EJBs do not support concurrency by default. Why should this be so
in the case of Stateless Session ejb's because in any case it does not
store any state information.

I want to use parameterized LIKE in EJB QL. I use WSAD 5.0.
I have tried with theese following two solutions without success: Please help me.
SELECT OBJECT(o) FROM Uppgift o WHERE o.objectId LIKE ?1
SELECT OBJECT(0) FROM Uppgift o WHERE LOCATE( ?1, o.description ) > 0

I am starting to write a Java Client Server App, I am comming from VB and
VC++.  I have done much reading and am ready to start laying out the class's
on paper.  I am planning to use beans as the access point to the db and have
my clients use the beans located on the server.  I dont ...

Need help in order to retrive the foreign key values from a 1-N relation.
I have 2 tables, User and Friend, where a User can have many Friends.
The User table has id as PK, while the Friend table has id as PK and userId
as FK.

We have an application that brings thousands of records from an Oracle
database (50,000+).  The application is developed in EJB, deployed on JBoss.
We're currently using arraylists in a stateless session bean to contain the
recordset and keep bumping into JVM heapsize problem.
