Javamail

Good morning to all.

I'm trying to use javamail for the first time. After the propper Javamail f.A.Q and documentation reading i create a jsp file with a simple email client which is working good except one thing. Every email that i send from my different varius email accounts is a multipart one and contains tow parts with the same message body .
Even a simple "test" word from outlook,gmail and hotmail is been send in two parts with the same body.
So in my code i have this java bean which gets the msg and returns the body

Code :

public final String getPart(Part p) throws Exception {		 
 
		if(p.isMimeType("text/html") || p.isMimeType("text/plain")){
 
			if(!body.equals((String)p.getContent())){
 
				logger.info("---- text/plain Message Part ----");
 
				body = body + (String)p.getContent();}
 
		}else if(p.isMimeType("multipart/*")){
 
			logger.info("------- MultiPart Message -------");
 
			Multipart mp = (Multipart)p.getContent();
 
			level++;
			int count = mp.getCount();
 
			for (int i = 0; i < count; i++)				
				getPart(mp.getBodyPart(i));
 
			level--;
 
		}else if(p.isMimeType("message/rfc822")){
 
			logger.info("--------- Nested Message --------");
 
			level++;
 
			getPart((Part)p.getContent());
 
			level--;
 
		}else{
 
			Object o = p.getContent();
			if (o instanceof String) {
 
				logger.info("--------- Simple String ---------");
				body += (String)o;
 
			} else if (o instanceof InputStream) {
 
				logger.info("---------- Inputstream ----------");
 
			    InputStream is = (InputStream)o;
			    int c;
			    while ((c = is.read()) != -1)
			    	body += c;
 
			} else {
				logger.info("---------- Uknown Type ----------");
 
				body += o.toString();
			}			
		}
 
		String filename = p.getFileName();
		String disp = p.getDisposition();
 
		if (level != 0 && disp != null ) {
 
			if(disp.equalsIgnoreCase(Part.ATTACHMENT)){
 
		    	if (filename == null)
		    		filename = "";
 
		    	try {
				    File f = new File(filename);
 
				    if (!f.exists()){
 
				    	((MimeBodyPart)p).saveFile(f);
 
				    }
 
				    body += "Επισυναπτόμενο: <a href=\"" + f.getAbsolutePath() + "\">" + filename + "</a>";
 
				} catch (IOException ex) {
				    logger.error("Failed to save attachment: " + ex);
				}
			}		    
		}
 
		return body;
	}

So my problem is that every email is been showing two times without any exception. Any ideas will be appreciated.

Thanks in advance..
