Hello, and thanks for your answers.

I'm developing a portlet which will upload files to server. The code of home.xhtml file is:

<f:view>
        <h:form id="welcomeForm" enctype="multipart/form-data">
            <t:inputFileUpload id="fileupload" value="#{myBean.upFile}"    size="20" />
            <h:commandButton value="Load the file" action="#{myBean.upload}" />
        </h:form>
 </f:view>

and MyBean.java:

import java.io.*;
import org.apache.myfaces.custom.fileupload.UploadedFile;

public class MyBean {

    private UploadedFile upFile;

     //setters, getters

    public String upload(){
        System.out.println("Uploading...");
        try {
            InputStream stream = upFile.getInputStream();
            long size = upFile.getSize();
            byte[] buffer = new byte[(int) size];
            stream.read(buffer, 0, (int) size);
            stream.close();
            System.out.println("File Upload Successful.");
        } catch (Exception ioe) {
            System.out.println("File Upload Unsuccessful.");
            System.out.println("//EXCEPTION");
            ioe.printStackTrace();
        }
        return null;
    }

}

But, when I submit the form nothing happens, the upload method of the bean don't run. And, if I delete the enctype attribute of h:form, the upload method upload run, but if I do that, I couldn't upload the file to the server.

Any body can help me, please?
