problema con crear applet de java

[laris11]

Ya arregle eso si me faltaba una libreria tal y como dijiste muchas gracias ^^. Ahora tengo otro problemilla y es que me da error estas dos funciones, osea no me captura la url bien


public String urlByPost()
{
try {
Main.this.output = new String();
URL u = new URL(Main.this.url);
String params = new String();

for (@SuppressWarnings("rawtypes") Map.Entry e : Main.this.postParams.entrySet()) {
params = params + ((String)e.getKey()).trim() + "=" + ((String)e.getValue()).trim() + "&";
}
params = params.replaceAll("&$", "");

URLConnection conn = u.openConnection();
((HttpURLConnection)conn).setRequestMethod("POST") ;
conn.setRequestProperty("User-Agent", Main.this.uaParam);
conn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(params);
writer.flush();

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
{
Main.this.output += inputLine;
}
in.close();
return Main.this.output.trim();
} catch (Exception ex) {
ex.printStackTrace();
}
return this.output.trim();
}

public String urlByGet()
{
try {
Main.this.output = new String();
URL u = new URL(Main.this.url);
URLConnection conn = u.openConnection();
((HttpURLConnection)conn).setRequestMethod("GET");
conn.setRequestProperty("User-Agent", Main.this.uaParam);

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
{
Main.this.output += inputLine;
}
in.close();

return Main.this.output.trim();
} catch (Exception ex) {
ex.printStackTrace();
}
return this.output.trim();
}
