How to get response from SOAP endpoint in java?

Question

I am very new to SOAP, so was looking into some programs online, this is what I came up with but I get a null response, must be some silly thing, but need little help

Answer 1

Do you really need to use bare SOAP classes? How about generating JAX-WS artifacts to get rid of all this boilerplate?

More info (incorporating ANT) here.

Answer 2

With cxf-codegen-plugin maven plugin you can create a client of the soap service quickly by adding these dependencies:

<dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>2.4.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>2.4.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-core</artifactId>
            <version>2.4.2</version>
        </dependency>

and adding this build section:

org.apache.cxf cxf-codegen-plugin 2.1.2 generate-sources generate-sources wsdl2java ${basedir}/target/generated-sources/cxf ${basedir}/src/main/resources/wsdlfile.wsdl -client -wsdlLocation -p com.package.for.generated.classes

then inside ${basedir}/target/generated-sources/cxf you will have classes required to call the web service and an example of how to do it.

Hope it helps!

Answer 3

Try with

   QName qn = new QName("http://www.webserviceX.NET","ElementName","web");

EDIT: Also, as others have suggested - you will be better off using generated client code here - Axis, JAX-WS etc are all options.

The correct code should be as below.

  QName bodyName = new QName("http://www.webserviceX.NET", "GetAtomicNumber");
  SOAPBodyElement bodyElement = sbody.addBodyElement(bodyName);
  QName qn = new QName("ElementName");

Answer 4

What you want to do is auto-generate Java code for this web service. The WSDL is here: http://www.webservicex.net/periodictable.asmx?wsdl

In Java, the tool to auto-generate the code is wsimport. You'll want to use something like this:

wsimport http://www.webservicex.net/periodictable.asmx?wsdl -p com.company.whateveruwant -Xnocompile -d . -keep

This will put the code you want in the specified package (here com.company.whateveruwant).

From there, all you have to do is simply invoke the SOAP method like a normal Java library:

PeriodictableSoap soap = new Periodictable().getPeriodictableSoap();
System.out.println(soap.getAtomicNumber("Iron"));

This prints out:

<NewDataSet>
  <Table>
    <AtomicNumber>26</AtomicNumber>
    <ElementName>Iron</ElementName>
    <Symbol>Fe</Symbol>
    <AtomicWeight>55.847</AtomicWeight>
    <BoilingPoint>3300</BoilingPoint>
    <IonisationPotential>7.9</IonisationPotential>
    <EletroNegativity>1.6400000000000001</EletroNegativity>
    <AtomicRadius>1.17</AtomicRadius>
    <MeltingPoint>1808</MeltingPoint>
    <Density>7874</Density>
  </Table>
</NewDataSet>

Answer 5

@Ricky, this is the correct code.

SOAPBody body = message.getSOAPBody();
QName bodyName = new QName("http://www.webserviceX.NET", "GetAtomicNumber");
SOAPBodyElement bodyElement = body.addBodyElement(bodyName);
SOAPElement symbol = bodyElement.addChildElement("MyMetal");
symbol.addTextNode("iron");
SOAPConnection connection = SOAPConnectionFactory.newInstance().createConnection();
SOAPMessage response = connection.call(message, endpoint);
connection.close();
message.writeTo(System.out);
System.out.println();
response.writeTo(System.out);
System.out.println();
