Spring-WS holidayRequest tutorial example

[Stefan2902]

Dear all,

I'm trying to follow the holidayRequest example of the Chapter 3 "Writing Contract-First Web Services" of the spring tutorial. Unfortunately I receive an exception if I call the WSDL.

I've started by adding a new "Dynamic Web Project" in Eclipse. Attachment 1 shows the project setup and it's artifacts.

The spring-ws-servlet.xml file looks as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans">

	<bean id="holidayEndpoint" class="com.mycompany.hr.ws.HolidayEndpoint">
		<constructor-arg ref="hrService" />
	</bean>

	<bean id="hrService" class="com.mycompany.hr.service.StubHumanResourceService" />

	<bean
		class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">
		<property name="mappings">
			<props>
				<prop key="{http://mycompany.com/hr/schemas}HolidayRequest">holidayEndpoint</prop>
			</props>
		</property>
		<property name="interceptors">
			<bean
				class="org.springframework.ws.server.endpoint.interceptor.PayloadLoggingInterceptor" />
		</property>
	</bean>

	<bean id="holiday"
		class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
		(1)
		<property name="schema" ref="schema" />
		(2)
		<property name="portTypeName" value="HumanResource" />
		(3)
		<property name="locationUri" value="/holidayService/" />
		(4)
		<property name="targetNamespace" value="http://mycompany.com/hr/definitions" />
		(5)
	</bean>

	<bean id="schema" class="org.springframework.xml.xsd.SimpleXsdSchema">
		(2)
		<property name="xsd" value="/WEB-INF/hr.xsd" />
	</bean>

</beans>

The web.xml file looks as follows:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
             http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
	version="2.4">

	<display-name>MyCompany HR Holiday Service</display-name>

	<!-- take especial notice of the name of this servlet -->
	<servlet>
		<servlet-name>spring-ws</servlet-name>
		<servlet-class>
			org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
	</servlet>

	<servlet-mapping>
		<servlet-name>spring-ws</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

</web-app>

The hr.xsd file looks as follows:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
        xmlns:hr="http://mycompany.com/hr/schemas"
        elementFormDefault="qualified"
        targetNamespace="http://mycompany.com/hr/schemas">
    <xs:element name="HolidayRequest">
        <xs:complexType>
            <xs:all>
                <xs:element name="Holiday" type="hr:HolidayType"/>                       
                <xs:element name="Employee" type="hr:EmployeeType"/>
            </xs:all>
        </xs:complexType>
    </xs:element>
    <xs:complexType name="HolidayType">
        <xs:sequence>
            <xs:element name="StartDate" type="xs:date"/>
            <xs:element name="EndDate" type="xs:date"/>                                  
        </xs:sequence>                                                                   
    </xs:complexType>
    <xs:complexType name="EmployeeType">
        <xs:sequence>
            <xs:element name="Number" type="xs:integer"/>
            <xs:element name="FirstName" type="xs:string"/>
            <xs:element name="LastName" type="xs:string"/>                               
        </xs:sequence>                                                                   
    </xs:complexType>
</xs:schema>

After exporting to WAR file and deploying to tomcat 6.0 I receive the following java exception when I try to call the WSDL file on http://localhost:8080/holidayService/holiday.wsdl:

I've added two libraries to my project properties which are jdom.jar and spring-ws-1.5.8-all.jar. Do I need to tell s.b. that these files need to be deployed as well? Maybe this could be the reason for above exception?!

I would appreciate any help on that.

Cheers,
Stefan

Hi Stefan,

could you please tell how did you end up with the "spring-ws-servlet.xml" that you posted?

Trying to follow the tutorial, I only get this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

</beans>

At the same time, the tutorial says:

(You can see the contents of the 'WEB-INF/spring-ws-servlet.xml' file for this example in ???.)

-- which points to this:

http://static.springsource.org/sprin....sws-conf-file

<bean class="org.springframework.ws.server.endpoint.mapp ing.PayloadRootQNameEndpointMapping">
<property name="mappings">
<props>
<prop key="{http://mycompany.com/hr/schemas}HolidayRequest">holidayEndpoint</prop>
</props>
</property>
<property name="interceptors">
<bean class="org.springframework.ws.server.endpoint.inte rceptor.PayloadLoggingInterceptor"/>
</property>
</bean>

To me, the two don't add up to what you've got.

To the Spring developers: could you please be more explicit in the tutorial?

(Alternatively, if somebody shows me how to indeed build a simple Spring WS, I'd be glad to work on the tutorial:-)).
