Hi Raist, thanks for the tip. I'm in the middle of managing a few things at the same time (including a new job the coming Monday). So, havent been able to get back to you on this any sooner. I've bookmarked this thread, and will certainly take time to digest your every word you wrote as soon as I can manage to sit down and cool my head. But, thanks.

[JBoss-user] [EJB/JBoss] - HELP! CMR -- generated SQL doesn't look right...
Hi, really frustating... been trying to get my CMR setup for last three days but
without much success (shame).
My setup is simple. I have three beans:
1. UserBean
2. GroupBean
3. GroupMembershipBean
Each User (UserBean) can belong to multiple Group(s) (GroupBean).
1. UserBean maps to table USERS, table schema:
Primary key: UIN
Other fields: login, email, ... etc
2. GroupBean maps to table GROUPS, table schema:
Primary key: UIN
Other fields: name, decription, ... etc
3. GroupMembershipBean maps to table GROUPMEMBERSHIP, table schema:
Composite Primary Key: {GROUPUIN, USERUIN}
Foreign key on USERUIN and GROUPUIN that points to table USERS and table GROUPS
There's a One-To-Many relationship between GroupBean (One-side) and GroupMembership
(Many-side).
1. GroupBean:

Thanks, I'm stiill reading up on one article:

Anyway, yes, i did put @ejb.pk-field method level tags on getters. But do we need
@ejb.bean primkey-field still? I guess we do - but we specify "field name" - NOT
"column name".
so... here's what I have in mind, not yet put to test however:

[JBoss-user] [EJB/JBoss] - CMR - with composite key
I'm going over this article on CMR http://technology.amis.nl/blog/index.php?p=90&page=3.

[JBoss-user] [EJB/JBoss] - Re: CMP - composite primary key - @ejb.primkey spec
So, I've implemented a primary key class "GroupMembershipKey" -- I still need to know
what I should specify for @ejb.bean primkey-field attribute.
My understanding is that @ejb.bean primkey-field is not mandatory. Will it suffice if
I just specify @ejb.pk-field on primary key getters? Example:
| /**
|* @ejb.persistent-field
|* @ejb.persistence
|*column-name="GROUPUIN"
|*sql-type="INTEGER"
|* @ejb.pk-field
|* @ejb.interface-method
|*/
| public abstract Integer getGroupUIN();
|
| NOTE: Same for getUserUIN()
|
And ...
| /**
| *
| * @ejb.bean
| * name="GroupMembershipEJB"
| * local-jndi-name="ejb/GroupMembership"
| * display-name="Group Membership EJB"
| * description="Group Membership Group EJB"
| * cmp-version="2.x"

| *

[JBoss-user] [EJB/JBoss] - Re: CMP - composite primary key - @ejb.primkey spec
Think I found part of the answer (Still need to know what XDoclet tags I need to specify) - Quoting J2EE Tutorial from Sun: Chapter: "Primary Keys for Container-Managed Persistence" If the primary key class does not belong to the J2SE or J2EE standard libraries, then you must implement the class and package it along with the entity bean. For example, if your entity bean requires a composite primary key (which is made up of multiple fields), then you need to provide a customized primary key class.

[JBoss-user] [EJB/JBoss] - CMP - composite primary key - @ejb.primkey spec
Hi, I have this GroupMembershipBean which has a composite primary key:
1. database field: GROUPUIN (Integer)
getter: Integer getGroupUIN()
setter: void setGroupUIN(Integer)
2. database field: USERUIN (Integer)
getter: Integer getUserUIN()
setter: void setUserUIN(Integer)
My question is, what should I specify in @ejb.bean's "primkey-field" attribute? Can I
specify "primkey-field" as a comma-delimited string:
@ejb.bean
| ...
| primkey-field "GROUPUIN, USERUIN" (Do I speicfy "database field name here?)
| ...
| public abstract class GroupMembershipBean implements EntityBean, Serializable,
Comparable {
| ...
| ...
| }
Then, for GroupUIN and UserUIN getters. specify "@ejb.pk-field" attribute (See code
below)
If not, do I have to implement a "primary key class" and specify "@ejb.pk class"
(corresponds to in "ejb-jar.xml")? Is this a MUST (can I make do
without)?
| public class GroupMembershipKey implements Serializable {
| public Integer GroupUIN;
| public Integer UserUIN;
|
|public GroupMembershipKey() {}
|
|public GroupMembershipKey(Integer GroupUIN, Integer UserUIN) {
| if(GroupUIN==null || UserUIN==null) { throw new Exception(); }
| this.GroupUIN=GroupUIN;
| this.UserUIN=UserUIN;
| return;
|}
|
|public Integer getGroupUIN() {
| return GroupUIN;
|}
|
|public Integer getUserUIN() {
| return UserUIN;
|}
|
|public boolean equals(Object o) {
|GroupMembershipKey key=null;
| if(o instanceof GroupMembershipKey) {
| key=(GroupMembershipKey) o;
|if(GroupUIN.equals(key.getGroupUIN) && UserUIN.equals(key.getUserUIN)) {
| return true;
| } else { return false; }
|} else {
| return false;
|}
|}
|
|public String toString() {
| StringBuffer buf=new StringBuffer("GroupMembershipKey ");
| buf.append(" Group UIN: ").append(GroupUIN);
| buf.append(" User UIN: ").append(UserUIN);
| return buf.toString();
|}
| }
For reference, here's GroupMembershipBean class:
| /**

[JBoss-user] [EJB/JBoss] - Re: hardcoded JNDI names on clientside...
anonymous wrote : This tag is optional, and lets you define whether or not a util
class should be generated, and whether to use the logical component name
(java:comp/env) or the physical JNDI name to do the lookup. If this tag is not
specified, the util class will be generated using logical lookups (provided the
subtask is used)
|
| XDoclet REF: http://xdoclet.sourceforge.net/xdoclet/tags/[EMAIL PROTECTED]
|
| Applies to: Applies to Entity Beans and Session Beans
What's "logical component name"? or "Physical JNDI name"? When I do look up, I do
something like this, using JNDI name as specified on "jboss.xml" JNDI-name-to-EJB-name
mapping section:
| context = new InitialContext();
| Object ref = context.lookup("ejb/UserAuthenticationManager"); //THAT's JNDI name -
is there distinction between "Physical" JNDI names and other type of JNDI name?
| authManagerHome = (AuthenticationManagerHome)PortableRemoteObject.narrow(ref,
AuthenticationManagerHome.class);
| authManager=authManagerHome.create();
|
Bean:
| /**

| * @ejb.home
| * remote-class="com.aa.samples.interfaces.AuthenticationManagerHome"
| *
| */
| public class AuthenticationManagerBean implements SessionBean {
| ...
| }
|
My understanding is that jndi-name="ejb/UserAuthenticationManager" gets rendered into
"jboss.xml" by XDoclet:
| EJB name to JNDI name mapping in "jboss.xml":
|
| UserAuthenticationManagerEJB
| ejb/UserAuthenticationManager
|
|
What's the distincation between:
1. Physical JNDI names
2. other kinds of JNDI names
3. Logical component names
Thanks!

| home = (GroupLocalHome) context.lookup("ejb/UserGroup");
| groups=home.findAllGroups();
| ...

|
Any suggestion?

[JBoss-user] [EJB/JBoss] - Re: CMP - failed to retrieve data from database - but NO exc
It worked!!! Did you hear me guys?!! It worked: p6spy capture: | 1098971495056|-1||resultset|SELECT t0_g.UIN FROM GROUPS t0_g|UIN = 1 | 1098971495057|-1||resultset|SELECT t0_g.UIN FROM GROUPS t0_g|UIN = 2 | 1098971495070|11|0|commit|| | 1098971586031|25|0|statement|SELECT t0_g.UIN FROM GROUPS t0_g|SELECT t0_g.UIN FROM GROUPS t0_g | 1098971586032|-1||resultset|SELECT t0_g.UIN FROM GROUPS t0_g|UIN = 1 | 1098971586033|-1||resultset|SELECT t0_g.UIN FROM GROUPS t0_g|UIN = 2 | 1098971586040|6|0|commit|| | Cause of death is that I forgot to include jbosscmp-jdbc.xml in the EJB jar!! Anyway, thankyou guys, thankyou! Appreciate it and really thanks for going over those code fragments I posted in my earlier messages. Thanks!!

I just made the modification, no and much to my dismay, it's not working unfortunately.

I'm not sure what it is... nothing is going to the database...
2. TO darranl:
2.1 What is the structure of the jar file?
That's a long story, there's:
a. EJB jar which contains the EJB implementation as well as META-INF with ejb-jar.xml
b. client jar, which includes the interface classes
c. WAR, which contains the JSP's, the libraries (ext jars) and the client jar (b).
d. EAR, which contains the EJB jar (a) as well as the WAR file (c).
I built it with XDoclet - can I send you the stuff by email? Anyway, for your
reference - this is part of the documentation:
| 7. Packaging Configurations:
| 7.1 right click project
| 7.2 Add four archives:
| 7.2.1 UserManagementEJB.jar
| a. add folder:
WEB-INF/classes
| include:
com/aa/samples/*.class, com/aa/samples/beans/*.class, com/aa/samples/interfaces/*.class
| b. add file:
META-INF/ejb-jar.xml, prefix: META-INF
| c. add file:
META-INF/jboss.xml, prefix: META-INF
| 7.2.2 UserManagementClient.jar
| a. add folder:
WEB-INF/classes
| include:
com/aa/samples/interfaces/*.class
| b. add file:
META-INF/ejb-jar.xml, prefix: META-INF
| c. add file:
META-INF/jboss.xml, prefix: META-INF
| 7.2.3 UserManagementWeb.war (NOTE: The name of
this file must corresponds to that in META-INF/application.xml)
| a. add folder: WEB-INF
| include:
*.xml,*.tld
| prefix:
