Using Spring-WS with JAXB2

[elewandowski]

Hi !

I have a question concerning integration of spring-ws with JAXB2.

I use :
<dependency>
<groupId>commons-httpclient</groupId>
<artifactId>commons-httpclient</artifactId>
<version>3.1</version>
</dependency>
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-oxm</artifactId>
<version>1.5.0</version>
</dependency>
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-ws-core</artifactId>
<version>1.5.0</version>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-xjc</artifactId>
<version>2.1.2</version>
</dependency>
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.1</version>
</dependency>
<dependency>
<groupId>org.springframework.ws</groupId>
<artifactId>spring-oxm-tiger</artifactId>
<version>1.5.0</version>
</dependency>
<dependency>
<groupId>javax.xml.soap</groupId>
<artifactId>saaj-api</artifactId>
<version>1.3</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.sun.xml.messaging.saaj</groupId>
<artifactId>saaj-impl</artifactId>
<version>1.3</version>
<scope>runtime</scope>
</dependency>

My JAXB2 classes are generated by :
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>

I have a problem with my endpoint. Here's the definition of my endpoint :

public class LogEndPoint extends MarshallingMethodEndpointAdapter {

public JAXBElement<LogResponseType> handlelogRequest(JAXBElement<LogRequestType> pRequest) {
.....
}

}

When I have this definition, Spring-ws says that there's no endpoint associated with my message because JAXBElement does not have the annotation @xmlRootElement

When I change my definition to :

public class LogEndPoint extends MarshallingMethodEndpointAdapter {

public LogResponseType handlelogRequest(LogRequestType pRequest) {
.....
}

}

I have an exception when Spring-WS wants to invoke my endPoint because object unmarshalled by JAXB is not an LogRequestType but an JAXBElement<LogRequestType>

So, what's wrong in a my configuration ? What is the good definition for my endPoint ?

Thanks for all and Thanks for the quality of your product.

You should use define your method as:

public LogResponseType handlelogRequest(JAXBElement<LogRequestType> pRequest) {

Thanks for your answer Arjen ! I will test this.

Sorry but it doesn't work, I have this exception returned to my client :
.LogResponseType com.cgi.test.spring.ws.LogEndPoint.handlelogReques t(javax.xml.bind.JAXBElement<com.cgi.test.spring.w s.log.LogRequestType>)]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint?

It seems to problem is tied to JAXBElement<LogRequestType> parameter :
MarshallingMethodEndpointAdapter.getUnmarshaller() .supports(method.getParameterTypes()[0]) return false
because org.springframework.oxm.jaxb.Jaxb2Marshaller.suppo rtsInternal return false
because clazz.getAnnotation(XmlRootElement.class) = null. clazz is JAXBElement<LogRequestType>

[elewandowski]

OK, I found the problem which resides in the classes generated by JAXB2 and, in fact, in my xsd.

My previous xsd looks like :

<element name="logRequest" type="tns:logRequestType"></element>

<complexType name="logRequestType">
<sequence>
<element name="header" type="tns:logHeaderType"></element>
<element name="logs" type="tns:logType" minOccurs="1" maxOccurs="unbounded"></element>
</sequence>
</complexType>

with this definition, JAXB2 does not generate the annotation @xmlRootElement, so when you unmarshall your xml, it generates a JAXBElement<logRequestType>.

I change my xsd :

<element name="logRequest">

<complexType>
<sequence>
<element name="header" type="tns:logHeaderType"></element>
<element name="logs" type="tns:logType" minOccurs="1" maxOccurs="unbounded"></element>
</sequence>
</complexType>
</element>

Now, JAXB2 generates a @xmllRootElement and when it unmarshall the xml, it generate a logRequest object, which is compatible with all spring-ws needs.

conclusion : the xsd types for the request and the response element must be anonymous.

hi,

I'm trying to use spring ws with jaxb2 marshalling/unmarshalling.
I have successfully created a webservice with xml parser, but its not what i need.

I got this exception when I tried to use the service:

08:53:37,808 ERROR [[spring-ws]] Allocate exception for servlet spring-ws
java.lang.IllegalArgumentException: Resource ServletContext resource [/classpath*:org/springframework/oxm/schema.xsd] does not exist
	at org.springframework.util.Assert.isTrue(Assert.java:65)

Here's my xsd file:

	<xs:element name="ServiceManagerActivateRequest">
		<xs:complexType>
			<xs:all>
				<xs:element name="serviceName" type="xs:string" />
				<xs:element name="parameters" type="xs:string" />
			</xs:all>
		</xs:complexType>
	</xs:element>
	<xs:element name="ServiceManagerIsActiveRequest">
		<xs:complexType>
			<xs:all>
				<xs:element name="serviceName" type="xs:string" />
				<xs:element name="parameters" type="xs:string" />
			</xs:all>
		</xs:complexType>
	</xs:element>
	<xs:element name="ServiceManagerDeactivateRequest">
		<xs:complexType>
			<xs:all>
				<xs:element name="serviceName" type="xs:string" />
				<xs:element name="parameters" type="xs:string" />
			</xs:all>
		</xs:complexType>
	</xs:element>

appContext file:

	<bean id="serviceManagerEndPoint"
		class="br.ctbc.azzu.accounter.ws.ServiceManagerEndPoint">
		<constructor-arg ref="marshaller" />
	</bean>

	<bean

			</list>
		</property>

	</bean>

	<bean id="manager"

		<property name="portTypeName" value="HumanResource" />

	</bean>

	<bean id="schema"
		class="org.springframework.xml.xsd.SimpleXsdSchema">
		<property name="xsd" value="/WEB-INF/hr.xsd" />
	</bean>
</beans>

Any help would be great.

thanks,
