   public void setUseFlash(boolean useFlash) {

    }

}

File.java

package WFMTJavaResources;

public class File 
{

    private String Name;
    private byte[] data;

    public String getName() {
        return Name;
    }
    public void setName(String name) {
        Name = name;
    }
    public byte[] getData() {
        return data;
    }
    public void setData(byte[] data) {
        this.data = data;
    }


 }

听众不会开火。请帮我找出它出错的地方？

多文件上传不适用于jsf 1.1.15和richfaces 3.3.3
