Some code, that i created and tested using Eclipse and the google
plugin, seems not to run while installed on the App Engine, no matter
what.
I have really no idea what it couldd be, Anyone else an idea?
By the way, the code for all files is listed below.
Main file:

for (Integer i = 0; i < cookies.length; i++) {

{

}
}

Long ipNo = Iphandler.ip2long(ip);
PersistenceManager pm = PMF.get().getPersistenceManager();
Query q = pm.newQuery(Address.class, "ip == ipParam && code ==
uidParam");
q.declareParameters("Long ipParam, String uidParam");
List<Address> result = (List<Address>) q.execute(ipNo, uid);
if (result.isEmpty()) {

pm.makePersistent(a);
}

c.setPath("/");
c.setDomain("http://poaphost.appspot.com";);

resp.setContentType("text/xml");
resp.setCharacterEncoding("ISO-8859-1");
resp.addCookie(c);
Date d = new Date();
Long i = d.getTime();
Double f = i.doubleValue() / 1000;
