The SOAP request

<?xml version="1.0" encoding="utf-16"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

The Java code


String soapXml = //
java.net.URL url = new java.net.URL("http://localhost:9081/myServiceWAR/services/MyService");
java.net.URLConnection conn = url.openConnection();

// Set the necessary header fields
conn.setRequestProperty("SOAPAction", "http://localhost:9081/myServiceWAR/services/MyService");
conn.setDoOutput(true);

// Send the request
java.io.OutputStreamWriter wr = new java.io.OutputStreamWriter(conn.getOutputStream());
wr.write(soapXml);
wr.flush();

// Read the response
java.io.BufferedReader rd = new java.io.BufferedReader(
new java.io.InputStreamReader(conn.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
