I want to know if I can work with auto-increment with CMP beans.
I have a table with 2 fields:
id (identity)
dbPass
dbUrl
dbUser
dbDriver
dbName
and when I use a create() method
ECollections collHome = collectionHome.create(dbPass,dbUrl,dbUser,dbDriver,dbName);
, the console display this error:
I want to change the CMP datasource on the fly.
Can I use CMP's in this context where I need to connect to different databases(with
absolutely identical structure)
for each client. Different databases mean different Datasources, hence how do I
uniquely associate a CMP Entity Bean with a single t
Have Jboss some API's to work with datasource ?

Consider a hypothetical application that needs to be deployed on a single app server
and has to service mulitple clients. Consider that there is a database per client.
Thus n databases for n clients. However, all of these database have the same
structure, and only the content varies.
Now to th

hi everybody,
I have a jbosscmp-jdbc.xml file with this piece of code
java:/skyline
MS SQLSERVER2000
.
.
This xml is on EJBs.jar file.
And mssql-ds.xml (on jboss_home/server/default/deploy) has these lines
skyline
jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=skyli
well, I have a lot of beans running with :
java:/skyline
MS SQLSERVER2000
and ...
I want to create other beans in the same jar file (EJBs.jar)
but these beans will be use a different jndi connection like
java:/skylineAdmin
MS SQLSERVER2000
Can I do that ?

so, how can I get the fields from the other bean that participate in the relationships
?
while (iter.hasNext()) {
EDocuments element = ((EDocuments) iter.next());
System.out.println("Abstract:" + element.getShortabstract());
EDocMetaDataLocal meta = element.getEDocMetaData
My Problem was because I didn't use a Local Interface.
Ok , I just use
EDocMetaDataLocal meta = element.getEDocMetaData();
but when I want to use any filed for example:
System.out.println(meta.getAuthor());
this error appear:
java.lang.NullPointerException
at org.jboss.ejb.plugins.local.E
ava.rmi.ServerException: RemoteException occurred in server thread; nested exception

Hi all!!
I've 2 tables that contain the same primary key (docid)
and both have diferent fileds for a document
One of that has all the basic fields for a document and the other has metadata for the
same document.
Obviously the relation is one-to-one
well, the names of the beans are : EDocuments and
But in my case both tables contain the same amount of row
And the data model for those tables is one-to-one relationships

do you have any document to implement a one-to-one relationships
I think the @ejb.relation is good in both case (2 beans) but I can't understand why I
can't call one bean to other by getDocidMetaData() method.

I've been doing a CMP with 3 integer fields.
So, when I create an use this finder:
* @ejb.finder
* query="SELECT OBJECT(c) FROM catparents c where c.parentId=?1"
* signature="java.util.Collection findByChild(java.lang.Integer catId)"
the result give me the collection of the same row.
