[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Hibernate Annotations or xml SQL-Mapping?

[commy]

Hi there!

I have a Problem with a project. We use Hibernate to store and manage persistent objects. At the moment, we use xml mapping files. But I'm not sure if it satisfies our needs.

The problem is: we use JSF. Saving new data is no problem, but edit allready stored data? I can't get it to work.

I tried the following:

The resource.java is mapped with a normal xml file, no problem with that.

Here's a jsf table with all the resources. 


  | <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
  | <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
  | 
  | <f:view>
  | 	<h:form>
  | 		<f:verbatim>
  | 			<b>Resources 
  | 		</f:verbatim>
  | 		<h:dataTable value="#{resourceutil.resources}" var="resource">
  | 			<h:column>
  | 				<f:facet name="header">
  | 					<h:outputText value="id" />
  | 				</f:facet>
  | 				<h:outputText value="#{resource.id}" />
  | 			</h:column>
  | 			<h:column>
  | 				<f:facet name="header">
  | 					<h:outputText value="name" />
  | 				</f:facet>
  | 				<h:outputText value="#{resource.name}" />
  | 			</h:column>
  | 			<h:column>
  | 				<f:facet name="header">
  | 					<h:outputText value="desc" />
  | 				</f:facet>
  | 				<h:outputText value="#{resource.description}" />
  | 			</h:column>
  | 			<h:column>
  | 				<f:facet name="header">
  | 					<h:outputText value="edit" />
  | 				</f:facet>
  | 				<h:commandLink action="#{resource.edit}" value="edit"><f:param name="id" value="#{resource.id}"/></h:commandLink>
  | 			</h:column>
  | 		</h:dataTable>
  | 		<br />
  | 	</h:form>
  | 	<h:form>
  | 	<h:commandButton action="addResource" value="Add" />
  | 	</h:form>
  | </f:view>
  | 

By clicking edit, i'd like to het on a page to edit the data stored in the resources.
resource.edit() returns a value, and we are navigate (by jsf navigation rules) to the following page:


  | <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
  | <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
  | 
  | <f:view>
  | 	<div align="left">
  | 	<h:form>
  | 		<f:verbatim>
  | 			<b>Add or Edit a Resource
  | 		</f:verbatim>
  | 		<h:panelGrid columns="2">
  | 			<h:outputText styleClass="portlet-font" value="Resource Name:" />
  | 			<h:inputText value="#{resource.name}" align="center" required="true" />
  | 			<h:outputText styleClass="portlet-font" value="Resource Description:" />
  | 			<h:inputText value="#{resource.description}" align="center"
  | 				required="true" />
  | 		</h:panelGrid>
  | 		<br />
  | 		<h:commandButton action="#{resource.save}" value="Add" />
  | 	</h:form> 
  | 	<h:form>
  | 	<h:commandButton action="viewResources" value="View Resources" />
  | 	</h:form>
  | 	</div>
  | </f:view>
  | 

How can i tell jsf which object it has to display? Or can I only do this if i use annotations / ejb?

I'm very thankfull for every information

Greetings, Markus
