    Hibernate Annotations or xml SQL-Mapping?

    Markus Balsiger Newbie

      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
