Getting NullPointerException when trying to view wsdl on browser.

Question

I have an enterprise application which is basically a spring web service.
I have used "org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition" for dynamic wsdl generation.
I use the following spring libraries spring ,
spring-jpa.jar
spring-oxm-1.5.8.jar
spring-oxm-tiger-1.5.8.jar
spring-web-2.5.jar
spring-webmvc.jar
spring-ws-1.5.8-all.jar
spring-ws-core-1.5.8.jar
spring-ws-core-tiger-1.5.8.jar
spring-ws-security-1.5.8.jar
spring-ws-support-1.5.8.jar
spring-xml-1.5.8.jar
spring.jar
And I use xmlparserv2.jar as xml library. Because If I don't use this library I get "oracle.xml.jaxp.JXDocumentBuilderFactory not found" exception.
Other xml libraries I use are: xercesImpl.jar, xml-apis.jar, XmlSchema-1.3.2.jar, xalan-2.7.0.jar, xdb.jar, xml.jar, xschema.jar
The issue is, application is deployed in weblogic 10.3.2 on a linux box.
Application is deployed fine, it is working fine. Request and response all are working as expected. But when I want to see wsdl, I am getting NullPointerException.
Application is deployed in the url: http://localhost:7001/springws-example
The exception I am getting is at the url: http://localhost:7001/springws-example/springws.wsdl
where springws.wsdl would be the wsdl name, with which it could be accessed.
This exception is occuring only on linux boxes. I have tested in two linux boxes, it behaves the same way.
In windows I have weblogic 10.3.3 , where everything is working fine. Wsdl is loaded on browser and soap end point address is updated with correct hostname, port and context root.
The exception I am getting is as follows,
Exception
java.lang.NullPointerException
at oracle.xml.parser.v2.XMLDocument.getDocumentURI(XMLDocument.java:2114)
at org.springframework.ws.transport.http.LastModifiedHelper.getLastModified(LastModifiedHelper.java:50)
at org.springframework.ws.transport.http.WsdlDefinitionHandlerAdapter.getLastModified(WsdlDefinitionHandlerAdapter.java:113)
at org.springframework.ws.transport.http.MessageDispatcherServlet.getLastModified(MessageDispatcherServlet.java:245)
Has anyone come across this issue?
Even if not, people having knowledge on linux and weblogic.. please help.
Thanks in advance.

Answer 1

How did you map your spring-ws 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>*.wsdl</url-pattern>
</servlet-mapping>and what properties did you configure?
<bean id="something" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
    <property name="schema" ref="schema"/>
    <property name="portTypeName" value="MyPort"/>
    <property name="locationUri" value="http://localhost:7001/springws-example/service/"/>
    <property name="targetNamespace" value="http://middlewaremagic.com"/>
</bean>In this case the WSDL could be reachable at http://localhost:7001/springws-example/service/something.wsdl
