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
