[JBoss-user] [Persistence CMP/JBoss] - problem with auto-increment field and CMP bean
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: javax.ejb.CreateException: Could not create entity:java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Cannot insert explicit value for identity column in table 'collections' when IDENTITY_INSERT is set to OFF. at org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractCreateCommand.performInsert(JDBCAbstractCreateCommand.java:303) at org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractCreateCommand.execute(JDBCAbstractCreateCommand.java:138) at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.createEntity(JDBCStoreManager.java:554) at org.jboss.ejb.plugins.CMPPersistenceManager.createEntity(CMPPersistenceManager.java:208) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.createEntity(CachedConnectionInterceptor.java:269) at org.jboss.ejb.EntityContainer.createHome(EntityContainer.java:737) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.ejb.EntityContainer$ContainerInterceptor.invokeHome(EntityContainer.java:1043) at org.jboss.ejb.plugins.AbstractInterceptor.invokeHome(AbstractInterceptor.java:88) at org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invokeHome(EntitySynchronizationInterceptor.java:197) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invokeHome(CachedConnectionInterceptor.java:214) at org.jboss.ejb.plugins.AbstractInterceptor.invokeHome(AbstractInterceptor.java:88) at org.jboss.ejb.plugins.EntityInstanceInterceptor.invokeHome(EntityInstanceInterceptor.java:89) at org.jboss.ejb.plugins.EntityLockInterceptor.invokeHome(EntityLockInterceptor.java:61) at org.jboss.ejb.plugins.EntityCreationInterceptor.invokeHome(EntityCreationInterceptor.java:28) at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:88) at org.jboss.ejb.plugins.TxInterceptorCMT.runWithTransactions(TxInterceptorCMT.java:267) at org.jboss.ejb.plugins.TxInterceptorCMT.invokeHome(TxInterceptorCMT.java:98) at org.jboss.ejb.plugins.SecurityInterceptor.invokeHome(SecurityInterceptor.java:92) at org.jboss.ejb.plugins.LogInterceptor.invokeHome(LogInterceptor.java:120) at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invokeHome(ProxyFactoryFinderInterceptor.java:93) at org.jboss.ejb.EntityContainer.internalInvokeHome(EntityContainer.java:483) at org.jboss.ejb.Container.invoke(Container.java:720) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.mx.capability.ReflectedMBeanDispatcher.invoke(ReflectedMBeanDispatcher.java:284) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:546) at org.jboss.invocation.local.LocalInvoker.invoke(LocalInvoker.java:101) at org.jboss.invocation.InvokerInterceptor.invoke(InvokerInterceptor.java:90) at org.jboss.proxy.TransactionInterceptor.invoke(TransactionInterceptor.java:46) at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:45) at org.jboss.proxy.ejb.HomeInterceptor.invoke(HomeInterceptor.java:173) at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:85) at $Proxy236.create(Unknown Source) at com.entrieva.skyline.sessionBeans.admin.SCollectionsBean.insertCollections(SCollectionsBean.java:171) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.ejb.StatelessSessionContainer$ContainerInterceptor.invoke(StatelessSessionContainer.java:683) at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(CachedConnectionInterceptor.java:185) at org.jboss.ejb.plugins.StatelessSessionInstanceInterceptor.invoke(StatelessSessionInstanceInterceptor.java:72) at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:84)
[JBoss-user] [Persistence CMP/JBoss] - Re: DataSource API's from JBoss
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 table for a particular datasource. Also, we do not want a different entity bean set for each database!

[JBoss-user] [Persistence CMP/JBoss] - Changing a Datasource at runtime
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 the problem: 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 table for a particular datasource. Also, we do not want a different entity bean set for each database!

[JBoss-user] [Persistence CMP/JBoss] - simplest one-to-one relationships bug
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 EDocMetaData
This is the code for EDocuments:
/**
* @ejb.bean name=EDocuments
* jndi-name=EDocumentsBean
* type=CMP
* schema=documents
* cmp-version=2.x
* primkey-field=docid
*
* @ejb.persistence
* table-name=documents
*
* @ejb.finder
*query=SELECT OBJECT(a) FROM documents as a
*signature=java.util.Collection findAll()
**/
/**
* @ejb.interface-method
*
* @ejb.relation
*name=EDocuments-EDocMetaData
*role-name=EDocuments-has-one-EDocMetadata
*
* @jboss.relation
*related-pk-field=docid
*fk-column=docid
*
*/
public abstract EDocMetaData getEDocMetaData();
/**
* @ejb.interface-method
* view-type=both
*/
public abstract void setEDocMetaData(EDocMetaData metaData);
and this is for EDocMetaData bean :
/**
* @ejb.bean name=EDocMetaData
* jndi-name=EDocMetaDataBean
* type=CMP
* primkey-field=docid
* schema=docmetadata
* cmp-version=2.x
*
* @ejb.persistence
* table-name=docmetadata
*
* @ejb.finder
*query=SELECT OBJECT(a) FROM docmetadata as a
*signature=java.util.Collection findAll()
*
**/
/**
* @ejb.interface-method
*
* @ejb.relation
*name=EDocuments-EDocMetaData
*role-name=EDocMetadata-has-one-EDocuments
* @jboss.relation
*related-pk-field=docid
*fk-column=docid
*/
public abstract EDocuments getEDocuments();
public abstract void setEDocuments(EDocuments document);
This is the code for ejb-jar.xml

Well,
Finally I'm using Lomboz for generate all deploy files and
all the file were generated well and the deploy files were good too.
But when I want to use the client tester like this :

throws NamingException {
return (com.Entrieva.Skyline.SessionBeans.SDocumentsHome)

}
private InitialContext getContext() throws NamingException {

props.put(InitialContext.INITIAL_CONTEXT_FACTORY,
org.jnp.interfaces.NamingContextFactory);
props.put(InitialContext.PROVIDER_URL, jnp://127.0.0.1:1099);
InitialContext initialContext = new InitialContext(props);
return initialContext;
}
public void testBean() throws CreateException, RemoteException, FinderException {
try {
SDocuments myBean = getHome().create();
Collection col = myBean.getAllDocumentByCategoryId(11);
// get all documents by category
Iterator iter = col.iterator();
while (iter.hasNext()) {
EDocuments element = ((EDocuments) iter.next());
System.out.println(Abstract: + element.getShortabstract());
EDocMetaData meta = element.getEDocMetaData();}
} catch (NamingException e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws RemoteException, CreateException,

}

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 View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3835254#3835254 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3835254 --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562alloc_id=6184op=click ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] [Persistence CMP/JBoss] - relationship doubt
Hi everybody! I've 2 tables : CatDocuments and Documents CatDocuments has docid and catid fields Documents has docid and docname fields The relation between both are with the docid field I want to get all the docs from documents where catid =x for example [select docname from catdocuments a inner join documents b on a.docid=b.docid where catid = xxx] well, I' been created a code like this in Documents bean /** * @ejb.interface-method * view-type=both * * @ejb.persistence * column-name = docid * * @ejb.relation *name=EDocuments-ECatDocuments *target-ejb=ECatDocuments *target-multiple=no *role-name=EDocuments-has-ECatDocuments * * @jboss.relation *related-pk-field=docid *fk-column=docid * */ public abstract Collection getCatDocuments(); /** * @ejb.interface-method * view-type=both */ public abstract void setCatDocuments(int docid); and in the CatDocuments bean I put the next code /** * @ejb.interface-method * view-type=both * * @ejb.persistence * column-name = docid * * @ejb.relation *name=EDocuments-ECatDocuments *target-ejb=EDocuments *target-multiple=yes *role-name=ECatDocuments-has-EDocuments * * @jboss.relation *related-pk-field=docid *fk-column=docid * */ public abstract Collection getDocuments(); /** * @ejb.interface-method * view-type=both */ public abstract void setDocuments(int docid); so, the question is 1) if the code above is right and 2) why I want to deploy the code that error appear org.jboss.deployment.DeploymentException: No ejb-relationship-role-name element found View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=3835016#3835016 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3835016 --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562alloc_id=6184op=click ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
