[Opensymphony-oscache] Working with oscache

[b]To regenerate the cache we do that:[/b]


String dirname = "/usr/local/oscache/application";
long timeIni = System.currentTimeMillis();
		File f1 = new File(dirname);
		if (f1.isDirectory())  {
	    		out.println("Directorio de " + dirname +"<br>");
				String s[] = f1.list();
	    		for (int i = 0; i < s.length; i++)  {
				File f2 = new File(dirname+"/"+s[i]);
				if (f2.isDirectory())  {
					continue;
	    		}
				else  {
					try{
					FileInputStream fis = new FileInputStream(f2);
					ObjectInputStream ois = new ObjectInputStream(fis);
					CacheEntry entrada = (CacheEntry) ois.readObject();
					ois.close();
					if(entrada.getURL()==null)
						continue;
					out.println("Limpiando "+entrada.getURL()+"... ");
					out.flush();
					String pagina = entrada.getURL().replaceAll("&","%26");
					URL server = new URL("http://foohost/deleteCache.jsp?URL=http://foohost/"+pagina);
					HttpURLConnection connection = (HttpURLConnection)server.openConnection();
					connection.connect();
					if(connection.getResponseCode()==200)
					{
						out.println("<b>[OK]</b>"+"<br>");
					}
					else
					{
						out.println("<b>[ERROR]</b>"+"<br>");
					}
					}
					catch(java.io.InvalidClassException e)
					{
					
					}
					catch(Exception ex){
						out.println(ex+"<br>");
						continue;
						}
	    		}
				}
		}  else  {
	    		out.println(dirname + " no es un directorio");
		}
		long timeFIN = System.currentTimeMillis();
		double tiempo=0.0;
		tiempo = (timeFIN-timeIni)/1000.0;
		out.println("Tiempo invertido: <b>"+tiempo+"</b> segundos<br>");


[b]We call a page named deleteCache which has this code.[/b]

 ServletCacheAdministrator admin = (ServletCacheAdministrator)
 application.getAttribute("__oscache_admin");
 String myKey = request.getParameter("URL");
myKey=generateKey(myKey);
Cache mycache = admin.getAppScopeCache(application);
mycache.flushEntry(admin.generateEntryKey(myKey,request,PageContext.APPLICATION_SCOPE));
out.println(urlOriginal);
response.sendRedirect(urlOriginal);
 }
 else
 {
	throw new Exception("Falta el parametro URL asociado");
 }
