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
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
I read a note from Alexey Loubyansky on http://www.junlu.com/msg/36487.html but I
can't get some other examples.
Could you give me an examples of your DataSource Factory ?
Thanks in advance!!!

hi everybody,
I have a jbosscmp-jdbc.xml file with this piece of code
jbosscmp-jdbc
java:/skyline
datasource-mappingMS SQLSERVER2000/datasource-mapping
.
.
/jbosscmp-jdbc
This xml is on EJBs.jar file.
And mssql-ds.xml (on jboss_home/server/default/deploy) has these lines
I think that is that I'm looking for.
I've 2 DB with the same tables and I need to choose one of them in every moment
depends of the client choose

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
well, I have a lot of beans running with :
java:/skyline
datasource-mappingMS SQLSERVER2000/datasource-mapping
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

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
ava.rmi.ServerException: RemoteException occurred in server thread; nested exception
is:
java.rmi.ServerException: RuntimeException; nested exception is:
java.lang.ClassCastException
at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:292)
at
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

somebody knows some tutorial to create one-to-one relationships ?
thanks in advance

Hi,
I've 2 beans one-one relationships
and this piece of code
InitialContext ctx = new InitialContext();
SDocuments myBean = getHome().create();
Collection col = myBean.getAllDocumentByCategoryId(11);
Iterator iter = col.iterator();
while (iter.hasNext()) {
EDocuments element =
ejb-relation
ejb-relation-nameEDocuments-EDocMetaData/ejb-relation-name
foreign-key-mapping/
ejb-relationship-role
ejb-relationship-role-nameEDocuments-has-one-EDocMetadata/ejb-relationship-role-name
key-fields/
/ejb-relationship-role
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.
thanks in advance

But in my case both tables contain the same amount of row
And the data model for those tables is one-to-one relationships

somebody knows how I can do this query with EJB-QL
Select A.catid FROM catparents A
where
(A.parentid IN (SELECT B.parentid from dbo.catparents B WHERE
(B.catid = 4) AND (B.depth = 0))
AND (A.depth = 0) AND (A.catid 4))
thanks in advance

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.
I mean
23 matches
