File Upload

[vasana]

I am trying to upload a file using s:fileUpload tag. How ever the file conten is always null.

Here is my web.xml
 

<filter>
   <filter-name>Seam Multipart Filter</filter-name>
   <filter-class>org.jboss.seam.web.MultipartFilter</filter-class>
    </filter>
   
    <filter-mapping>
       <filter-name>Seam Multipart Filter</filter-name>
       <url-pattern>*.seam</url-pattern>
    </filter-mapping>

My component.xml

<component class="org.jboss.seam.web.MultipartFilter">
       <property name="createTempFiles">true</property>
       <property name="maxRequestSize">10000000</property>
       <property name="url-pattern">*.seam</property>
   </component>

My view,

------
<td colspan="2"><s:fileUpload data="#{sarmgr.fileData.data}"  fileName="#{sarmgr.fileName}" 
fileSize="#{sarmgr.fileSize}"  accept="" style=" width : 99%;"  /> </td>

------

and my Backing EJB is,

private String fileName;
    private Integer fileSize;
    private byte[] data;
    private String contentType;
@Begin(join = true, flushMode = FlushModeType.MANUAL)
     public String addTask() {
          if (addedTasks == null) {
               addedTasks = new ArrayList<OsaTask>(0);
System.err.println("**************************************:::::::::"+fileData.getData());
 // This always prints null

I am i missing or doing wrongly?

Can you post the whole backing bean...

maybe in the view you need to reference sarmgr.data rather than sarmgr.fileData.data.

Also you have your form set to

   <h:form enctype="multipart/form-data">

[cremersstijn]

can you post also the whole view.
You can't do anfile upload with an ajax request.

               addedTasks = new ArrayList<OsaTask>(0);
          }
      System.err.println("**************************************:::::::::"+fileData.getData());
}
  
 }

I was looking for the button that submit your form, but i can't find it in your view.
Make sure that you don't submit with an ajax request.

[danielc.roth]

I assume you have a have something like

<h:commandXXXX action="#{sarmgr.addTask}">

and

getters/setters for data/fileName/fileSize?

I get a zero length byte array if I submit a form with no file chosen, so could you try to check that the setData(byte[] data) actually is called (and set to null)?

[vasana]

Thanks Roth i will try that way

[gauravsinghc]

hey ,
did you get this working a i am also facing the same problem

[vasana]

Hi,
Yes I got it working.Prolem is I was using a4j:commandbutton ( which is Ajax based) When i changed it to h:commandButton it worked. Good luck.
