Problems by getting info out of XML file with a HTTP request

Question

Hi,
I have a litte question. I'm working on an application that works together with google maps. In my java code, I get general information about address out of one database table, and I want to add some geographic information like coordinates that I want to retrieve from Google Maps through HTTP:
Right now my code is like:
while (resultSet.next())
                         title = resultSet.getString("title").replaceAll("'","''").toUpperCase();
                         author = resultSet.getString("author").replaceAll("'","''").toUpperCase();
                         location = resultSet.getString("location").replaceAll("'","''").toUpperCase();
                         straatnaam = resultSet.getString("straatnaam").replaceAll("'","''").toUpperCase();
                         nummer = resultSet.getString("nummer");
                         landcode = resultSet.getString("landcode").replaceAll("'","''").toUpperCase();
                         address = straatnaam + " " + nummer + " , " + location + " " + landcode;
                         url = "http://maps.google.com/maps/geo?q=" + address + "&output=xml&key=+key+";
                         String query = "INSERT INTO data2 VALUES ('" + i + "','" + title + "','" + author + "','" + resultSet.getString("date1") + "','" + resultSet.getString("date2") + "','" + location + "','" + resultSet.getString("postcode") + "','" + straatnaam + "','" + resultSet.getString("nummer") + "','" + landcode + "','+something like url.getCoordX+','something like url.getCoordY')";
                         success = sql2.executeUpdate(query);
                         i++;
Now I don't know how I can handle that. Is it possible to do an HTTP request in Java without using Java Script of servlets? I just want to get the X and Y coordinates out of the XML file.
The XML file will be something like:
<kml xmlns="http://earth.google.com/kml/2.0">
<Response>
<name>1600 amphitheatre mountain view ca</name>
<Status>
<code>200</code>
<request>geocode</request>
</Status>
<Placemark>
<address>
1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA
</address>
<AddressDetails Accuracy="8">
<Country>
<CountryNameCode>US</CountryNameCode>
<AdministrativeArea>
<AdministrativeAreaName>CA</AdministrativeAreaName>
<SubAdministrativeArea>
<SubAdministrativeAreaName>Santa Clara</SubAdministrativeAreaName>
<Locality>
<LocalityName>Mountain View</LocalityName>
<Thoroughfare>
<ThoroughfareName>1600 Amphitheatre Pkwy</ThoroughfareName>
</Thoroughfare>
<PostalCode>
<PostalCodeNumber>94043</PostalCodeNumber>
</PostalCode>
</Locality>
</SubAdministrativeArea>
</AdministrativeArea>
</Country>
</AddressDetails>
<Point>
<coordinates>-122.083739,37.423021,0</coordinates>
</Point>
</Placemark>
</Response>
</kml>
many greetings and thanks in advance

Hi, sorry for being not so clear. My question was actually if it is possible to do a HTTP request in Java without using servlets or being in Java Script. Actually my question was more specific for Google maps, because it didn't seem to work. It was my mistake, and already solved, to forget to make the webservice-call "URL-encoded". Because of that, I always received a HTTP 400 error, and that's why I thought it wouldn't be possible.
But now I have another, perhaps for you guys stupid question. The result I get from the webservice URL is of the form:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.0">
<Response>
     <name>nieuwelaan 38, Hamme</name>
     <Status>
          <code>200</code>
          <request>geocode</request>
     </Status>
     <Placemark id="p1">
          <address>Nieuwelaan 38, 9220 Hamme, Hamme, Belgium</address>
          <AddressDetails Accuracy="8" xmlns="urn:oasis:names:tc:ciq:xsdschema:xAL:2.0">
          <Country>
               <CountryNameCode>BE</CountryNameCode>
               <AdministrativeArea>
                    <AdministrativeAreaName>Vlaams Gewest</AdministrativeAreaName>
                    <SubAdministrativeArea>
                         <SubAdministrativeAreaName>Oost-Vlaanderen</SubAdministrativeAreaName>
                         <Locality>
                              <LocalityName>Hamme</LocalityName>
                              <DependentLocality>
                                   <DependentLocalityName>Hamme</DependentLocalityName>
                                   <Thoroughfare>
                                        <ThoroughfareName>Nieuwelaan 38</ThoroughfareName>
                                   </Thoroughfare>
                                   <PostalCode>
                                        <PostalCodeNumber>9220</PostalCodeNumber>
                                  </PostalCode>
                             </DependentLocality>
                        </Locality>
                    </SubAdministrativeArea>
               </AdministrativeArea>
         </Country>
         </AddressDetails>
         <Point>
               <coordinates>4.126295,51.097724,0</coordinates>
         </Point>
     </Placemark>
</Response>
</kml> Now I want to get the value of the coordinates field.
This is my code:
address = URLEncoder.encode(address, "UTF-8");
urlString = "http://maps.google.com/maps/geo?q=" + address + "&output=xml&key=ABQIAAAA9fEXNK-q6vKpPU0JCmPPkxQjbVBpjtblJJYkDfbMo0e51afwehRmujfvBtJqx1Qehg6e6QgCRY8poA";
url = new URL(urlString);
XPath xPath = XPathFactory.newInstance().newXPath();
Document domDoc = processData(url);
path = "/kml/Response/Placemark/Point/coordinates";
coord = xPath.evaluate(path, domDoc);
System.out.println("coord : " + coord);Now, in the last line, by writing out the value of coord to my screen, I get the value "1", instead of "4.126295,51.097724,0" I would expect, anyone knows what I'm doing wrong?
