    file upload problem null

    Jakub Wierzgala Newbie

      Hi everyone,


      I Am trying to develop a relatively Web 2.0 application, and 6 days ago I faced a problem with <s:fileUpload> tag. I get null for my byte array holding data and also for a contentType. I checked that even setters aren’t called. I wanted to see what is in the request so I added my own filter wrapped around Seam MultipartFilter. It shows basic info about request. Every time I send a request (except request from logging page) the length of request is -1 and contentType is null. I am really confused and stuck for good. I hope somebody will know how to solve this issue. I suspect the answer will be trivial.


      Here is my form



      <s:validateAll>
      <h:form id="UploadPhotoForm" enctype="multipart/form-data">
                      <fieldset>
                      <s:decorate id="imageField">
                              <s:fileUpload id="imageData" accept="image/*"
                              data="#{upload.imageData}"
                              contentType="#{upload.imageContentType}"
                              fileName="#{upload.title}" />
                      </s:decorate>
                      <s:button id="save" value="Upload" action="#{upload.savePicture}"/>
                      </fieldset>
      </h:form>
      </s:validateAll>



      And my action


      @Name("upload")
      @Scope(ScopeType.PAGE)
      @Local
      public class UploadPictureAction implements Serializable
      {
              @In
              User user;
              
              @Logger
              Log log;
              
              private static final long serialVersionUID = 1L;
      
              private byte[] imageData;
              private String imageContentType;
              private String title;
              
              
              public byte[] getImageData() 
              {
                      return imageData;
              }
              public void setImageData(byte[] imageData) 
              {
                      this.imageData = imageData;
                      System.out.println("Value:"+imageData);
              }
              public String getImageContentType() 
              { 
                      return imageContentType; 
              }
              public void setImageContentType(String imageContentType) 
              {
                      this.imageContentType = imageContentType;
              }
              public String getTitle() {
                      return title;
              }
              public void setTitle(String title) {
                      this.title = title;
              }
              
              public void savePicture()
              {
                      PicturesManager pm = PicturesManager.getInstance();
                      try
                      {
                              System.out.println("imageContentType:"+imageContentType);
                              System.out.println("imageData:"+imageData);
                      }
                      catch(Exception e)
                      {
                              log.error(e.getMessage(),e);
                      }
              }
