HttpEntity resEntity = responsePOST.getEntity();
if (resEntity != null) {
retValue = "";
String line = "";
InputStream in = responsePOST.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in, "windows-1252")); // ANSI CODE
while(null != (line = reader.readLine()))
{
retValue += line;
}
}
else
{
retValue = "ERROR";
retValue += "-Response";
}

e.printStackTrace();
retValue = "ERROR";
retValue += e.getMessage();

HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
params.setBooleanParameter("http.protocol.expect-continue", false);
HttpClient client = new DefaultHttpClient(params);
//String postURL = "http://www.ean-suche.de/perl/ean-search.pl";

String content = consume(responsePOST.getEntity());
Matcher matcher = PRODUCT_NAME_PRICE_PATTERN.matcher(content);
String one = "";
String two = "";
if (matcher.find()) {
one = matcher.group(1);
//two = matcher.group(2);
