6) Trying to generate the input with jaxb:
I used this tutorial:
http://camel.apache.org/tutorial-business-partners.html
6a) in the camel pom.xml, I add:
<dependency>
<artifactId>camel-jaxb</artifactId>
<groupId>org.apache.camel</groupId>
<version>1.4.0</version>
</dependency>
and
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
</plugin>
that respectively import the jaxb library and automatically generates java
classes.
And then I save the following xsd into src/main/xsd/messageHello.xsd:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xs:schema elementFormDefault="qualified" version="1.0"
targetNamespace="http://servicemix.apache.org/test3";
xmlns:tns="http://servicemix.apache.org/test3";
xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:element name="message" type="xs:string">
</xs:element>
</xs:schema>
Run mvn install: the libraries are downloaded if not present and the build
is OK.
New auto generated classes are in target/generated-sources/jaxb
7) Trying to generate the output with java2wsdl:
in the camel pom.xml, i add :
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>2.2.2</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<configuration>
<sourceRoot>${basedir}/target/generated-sources/wsdl</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>${basedir}/src/main/resources/helloWorld.wsdl</wsdl>
</wsdlOption>
</wsdlOptions>
</configuration>
<goals>
<goal>wsdl2java</goal>
</goals>
</execution>
</executions>
</plugin>
Run mvn install: the libraries are downloaded if not present and the build
is OK.
New auto generated classes are in target/generated-sources/wsdl
8) I create a new java class to test those two interfaces:
public static void main(String[] args) {
// read an xml input
String jaxbContext1 = "org.apache.servicemix.test3";
String input = "<message
xmlns=\"http://servicemix.apache.org/test3\";>Hello</message>";
String inputWS = null;
try {
JAXBContext jc = JAXBContext.newInstance(jaxbContext1);
Unmarshaller u = jc.createUnmarshaller();
Object appDefaults = u.unmarshal(new
ByteArrayInputStream(input.getBytes()));
inputWS = ((JAXBElement<String>)appDefaults).getValue();
System.out.println(inputWS);
} catch (Exception e) {
e.printStackTrace();
}
// generate the SOAP output
HelloWorld hw = new HelloWorld();
HelloWorldPortType client = hw.getHelloWorldSOAP11PortHttp();
String output = client.hello(inputWS);
System.out.println(output);
}
prints:
Hello
Hello World
The aim is now to convert the input XML message to a SOAP message:
8a)
<message xmlns="http://servicemix.apache.org/test3";>Hello</message>
---->
<ns0:hello xmlns:ns0="http://ode/bpel/unit-test.wsdl";>
<TestPart>Held</TestPart>
</ns0:hello>
and to convert back SOAP response to XML:
8b)
<helloResponse xmlns:odens="http://ode/bpel/unit-test.wsdl";>
<TestPart xmlns:q0="http://ode/bpel/unit-test.wsdl";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>Hello World</TestPart>
</helloResponse>
---->
<response xmlns="http://servicemix.apache.org/test3";>Hello
World</response>
Using the org.apache.cxf, I don't know how to create a SOAP message instead
of call the WS.
Does something has to be done differently?
Does someone know how to match the pieces I have?
