two spring-ws applications on one tomcat wsdl problem

[kayser]

Hi,

I ran into a strange behaviour I cannot see where it is coming from. I have two spring-ws applications, both running on tomcat6. Both have different wsdl files, one is created by spring-ws using xsd, the other one is a wsdl document shown by spring-ws.

When I deploy both of them, it depends on which wsdl I call first, the other one will not be shown on call in the browser but instead a 500 error.

I use spring-ws 1.5.9

these are my spring-ws-servlet.xml:

	<bean id="AMMClient"
		class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">
		<constructor-arg value="classpath:AMMClient.wsdl" />
	</bean>

and the second one throwing the exception in this case:

	 <bean id="MeteringPointDataService" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">  
	    <property name="schema" ref="schema"/>                                           
	    <property name="portTypeName" value="MeteringPointData"/>                      
	    <property name="locationUri" value="/services/MeteringPointData"/>                         
	    <property name="targetNamespace" value="http://www.example.com/mpds/20100806"/>     
	</bean>
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	  <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	  <property name="prefix" value="/"/>
	  <property name="suffix" value=".jsp"/>
	</bean>


	<bean id="schema" class="org.springframework.xml.xsd.SimpleXsdSchema">              
	    <property name="xsd" value="classpath:MeteringPointDataService.xsd"/>
	</bean>

I use jaxb2 and saajSoapMessageFactory in both apps, both configured in the main config up and running.


Here is the output in the browser:

Has anybody an idea why this happens?

Thanks for the advice!

I added an exclusion to maven pom.xml and it worked. Here's the snipped:
