[jboss-user] [JBoss Seam] - FileUpload

[jknotzke]

   Hi,

  I have what's got to be a very basic Seam question. I am using SEAM 2.0 BETA.

  I am simply trying to upload a CSV file. Here's the code:


  | 
  | ....
  | import static org.jboss.seam.ScopeType.SESSION;
  | 
  | import java.io.Serializable;
  | 
  | import javax.persistence.Entity;
  | import javax.persistence.Id;
  | import javax.persistence.Table;
  | 
  | import org.hibernate.validator.Length;
  | import org.hibernate.validator.NotNull;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.Scope;
  | 
  | @Entity
  | @Name("uploadedWorkout")
  | @Scope(SESSION)
  | public class UploadedWorkout implements Serializable
  | {
  |     private byte[] uploadedFile;
  |     @Id @NotNull
  |     private String fileName;
  |     private String contentType;
  | 
  |    public UploadedWorkout()
  |    {
  |    }
  | 
  |     public String getFileName()
  |     {
  |         return fileName;
  |     }
  | 
  |    ........ sets and gets
  | 


   Action Class
 

  | import javax.ejb.Stateless;
  | import org.jboss.seam.annotations.Name;
  | import org.jboss.seam.annotations.In;
  | import org.jboss.seam.annotations.Logger;
  | import org.jboss.seam.log.Log;
  | import org.jboss.seam.faces.FacesMessages;
  | import org.jboss.seam.annotations.Scope;
  | import static org.jboss.seam.ScopeType.SESSION;
  | 
  | @Stateless
  | @Scope(SESSION)
  | @Name("uploadWorkout")
  | public class UploadWorkoutBean implements UploadWorkout {
  | 
  |     @Logger private Log log;
  |     @In(value="uploadedWorkout", create=true)
  |     private UploadedWorkout uploadedWorkout;
  | 
  |     @In FacesMessages facesMessages;
  | 
  |     public void uploadWorkout()
  |     {
  |         //implement your business logic here
  |         log.info("Content Type is: " + uploadedWorkout.getContentType());
  |         log.info("FileName is: " + uploadedWorkout.getFileName());
  |         log.info("uploadWorkout.uploadWorkout() action called");
  |         facesMessages.add("uploadWorkout");
  |     }
  | 

    JSF:

    


  | 
  |     <ui:composition xmlns="http://www.w3.org/1999/xhtml"
  |                 xmlns:s="http://jboss.com/products/seam/taglib"
  |                 xmlns:ui="http://java.sun.com/jsf/facelets"
  |                 xmlns:f="http://java.sun.com/jsf/core"
  |                 xmlns:h="http://java.sun.com/jsf/html"
  |                 xmlns:rich="http://richfaces.ajax4jsf.org/rich"
  |                 xmlns:a="https://ajax4jsf.dev.java.net/ajax"
  |                 template="layout/template.xhtml">
  | 
  | <ui:define name="body">
  | 
  |     <h:messages globalOnly="true" styleClass="message"/>
  | 
  |     <rich:panel>
  |         <f:facet name="header">Upload Workout</f:facet>
  | 
  |         <h:form id="uploadedWorkoutForm">
  |         <s:fileUpload id="inUploadFile"
  |                            data="#{uploadedWorkout.uploadedFile}"
  |                            fileName="#{uploadedWorkout.fileName}"
  |                            contentType="#{uploadedWorkout.contentType}"
  |                            styleClass="fileUploadInput" />
  | 
  | 
  |             <h:commandButton id="uploadWorkout" value="uploadWorkout!"
  |                              action="#{uploadWorkout.uploadWorkout}"/>
  | 
  |         </h:form>
  | 
  |     </rich:panel>
  | 
  | </ui:define>
  | 
  | </ui:composition>
  | 

    The properties in uploadedFile are always NULL. As a matter of fact, I had to stuff create=true in because uploadedFile itself was null.

    If I swap:


  |     @In(value="uploadedWorkout", create=true)
  |     private UploadedWorkout uploadedWorkout;
  | 

   for


  |     @In
  |     private User user;
  | 

   ...which is a component I successfully used for registration and login, all works.. So the problem is with UploadedWorkout..

   Any ideas ?

   Thanks.
