Upload a file with JBoss Seam

Uploading a file with JBoss Seam is a really simple thing thaks to the component

<s:uploadFile />

Here is a use in a view :

  <f:facet name="header">Upload a file</f:facet>
        <br/>
        
        <h:form id="fooForm" enctype="multipart/form-data">
        
           <s:fileUpload id="file" 
    data="#{uploadHandler.file}"    
    accept="image/jpg"/>
      
      <h:inputText 
    converter="#{bankAccountConverter}" 
    value="#{myBean.bankAccount}" />
        
            <h:commandButton 
    id="upload" 
    value="Upload !!" 
                action="#{uploadHandler.handleUpload}"/>          
        
        </h:form>

Now here is the use on the component side :

@Name("uploadHandler")
@Scope(ScopeType.EVENT)
public class UploadHandler {
  
 @In(value="#{facesContext}")
 FacesContext facesContext;
 
 @Logger private Log log;
 
 
 private byte[] file;  
 
 public void handleUpload() throws IOException{
  
  String path = ((ServletContext) facesContext.getExternalContext().getContext()).getRealPath("/my/files/dir");
  File f = new File(path,"myFile.txt");
  log.info(f);
  FileOutputStream fo = new FileOutputStream(f);
  fo.write(file);
  fo.flush();
  fo.close();
 
 }

 public byte[] getFile() {
  return file;
 }

 public void setFile(byte[] file) {
  this.file = file;
 }

}

Et voila !!
