1. Skriv en testklass: Main

Vi skriver en testklass Main.java som körs från prompten och tar tre argument. Det första vi gör är att använda klassen CalculatorServiceLocator för att komma åt en stubbe som implementerar gränssnittet CalculatorPortType. Du kan titta på klassen på:

•  Main.java 

        CalculatorServiceLocator loc=null;
        CalculatorPortType stub = null;

        System.out.println("====================================");
        System.out.println("Main 1. Try locate service..");
        System.out.println("====================================");
        try{
            loc = new CalculatorServiceLocator();
            System.out.println("New CalculatorServiceLocator created.");
            stub = loc.getCalculator();
            System.out.println("CalculatorPortType created.");
        }catch( Exception e){
            System.err.println("Error when trying to find Calculator Service!");
            System.err.println("Check if service is deployed or server down.");
            e.printStackTrace();
            System.exit(2);
        }

                DivisionRequestType drt= new DivisionRequestType(a1,a2);
                floatRes= stub.division(drt);

2. Test 1: Division 3/9

Efter att Main är kompilerad testkör vi den på detta sätt:

[olle@dev1]$ cd classes/ [olle@dev1]$ java -cp .:$AXIS_CLASSPATH Main DIV 3 9 ==================================== Main 1. Try locate service.. ==================================== log4j:WARN No appenders could be found for logger (org.apache.axis.i18n.ProjectResourceBundle). log4j:WARN Please initialize the log4j system properly. New CalculatorServiceLocator created. CalculatorPortType created. ==================================== Main 2. Check parameters ==================================== ==================================== Main 3. Try execute command.. ==================================== ==================================== Main 4. Print result.. ==================================== The result of the operation DIV( 3, 9 ) was 0.33333334 Program finished!

Verkar funka. När vi kör programmet ovan skickas följande SOAP-meddelanden mellan klient och server:

<?xml version = '1.0' encoding = 'UTF-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <division xmlns="http://www.programmera.net/ws/Calculator"> <divisionRequestPart xmlns=""> <dividend>3</dividend> <divisor>9</divisor> </divisionRequestPart> </division> </soapenv:Body> </soapenv:Envelope>

Och svaret är:

<?xml version = '1.0' encoding = 'utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <divisionResponse xmlns="http://www.programmera.net/ws/Calculator"> <divisionReturn xmlns="">0.33333334</divisionReturn> </divisionResponse> </soapenv:Body> </soapenv:Envelope>

3. Test 2: Division 3/0

Nu ska vi testa att köra ett exempel som resulterar i ett SOAP-fault, nämligen division med noll:

[olle@dev1]$ java -cp .:$AXIS_CLASSPATH Main DIV 3 0 ==================================== Main 1. Try locate service.. ==================================== log4j:WARN No appenders could be found for logger (org.apache.axis.i18n.ProjectResourceBundle). log4j:WARN Please initialize the log4j system properly. New CalculatorServiceLocator created. CalculatorPortType created. ==================================== Main 2. Check parameters ==================================== ==================================== Main 3. Try execute command.. ==================================== Error when trying to execute command! AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.generalException faultSubcode: faultString: faultActor: faultNode: faultDetail: {http://www.programmera.net/ns/Calculator}DivideZeroFaultType:0Division by zero is not possible. {http://xml.apache.org/axis/}exceptionName:net.programmera.www.ns.Calculator.DivideZeroFaultType {http://xml.apache.org/axis/}hostname:okullberg-pc at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494)

Såhär ser SOAP-förfrågan ut:

<?xml version = '1.0' encoding = 'UTF-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <division xmlns="http://www.programmera.net/ws/Calculator"> <divisionRequestPart xmlns=""> <dividend>3</dividend> <divisor>0</divisor> </divisionRequestPart> </division> </soapenv:Body> </soapenv:Envelope>

Som svar får vi följande SOAP-meddelande:

<?xml version = '1.0' encoding = 'utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <soapenv:Fault> <faultcode>soapenv:Server.generalException</faultcode> <faultstring/> <detail> <ns1:DivideZeroFaultType xmlns:ns1="http://www.programmera.net/ns/Calculator"> <offending-value>0</offending-value> <comment>Division by zero is not possible.</comment> </ns1:DivideZeroFaultType> <ns2:exceptionName xmlns:ns2="http://xml.apache.org/axis/">net.programmera.www.ns.Calculator.DivideZeroFaultType</ns2:exceptionName> <ns3:hostname xmlns:ns3="http://xml.apache.org/axis/">okullberg-pc</ns3:hostname> </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope>

Vi ser att "faultcode" är "Server", vilket betyder att servern tolkar detta fel som ett serverfel.
