Struts 1 File Upload

Struts 1 re-encapsulates Apache Commons-fileupload to encapsulate uploaded files as formfile Objects

Define Uploadform:

Private formfilefile;       Upload the file private stringtext;    File notes//omit setter, getter

Jsp:

  

  

  
Action to handle the upload operation:

  

  

  
Uploadform uploadform = (uploadform) Form; StringBuffer buffer = new StringBuffer (); if (uploadform.getfile () = null && uploadform.getfile (). GetSize () >0) {//Get folder/web-inf/classes File CLA           sses = new File (GetClass (). getClassLoader (). GetResource (""). GetFile ());      Get folder/upload file Uploadfolder = new file (Classes.getparentfile (). Getparentfile (), "upload");       Uploadfolder.mkdirs ();           Save to/upload folder under File File = new file (Uploadfolder, Uploadform.getfile (). GetFileName ());      Outputstreat ous = null;      InputStream ins = null;             try{byte [] byt = new byte [1024];             int len = 0;             Ins =uploadform.getfile (). getInputStream ();             ous = new FileOutputStream (file);             while (len = Ins.read (byt))!=-1) {ous.write (Byt,0,len);             }}finally{Ins.close ();      Ous.close (); }//Click to download Buffer.append ("File:" + "<a href=upload/>" +fIle.getname () + "target=_blank>" +file.getname () + "</a><br/>");} else{buffer.append ("No file selected! <br/> ");} Buffer.append ("Remarks:" + uploadform.gettext () + "<br/>"), Response.setcharacterencoding ("UTF-8"); Response.getwriter ().
