Spring Boot Starter Integration and Starter WS not playing well together?

I'm working on a spike to try to exercise a number of technologies with spring boot (1.1.6.RELEASE), gradle (2.1) and Java 1.8. So we are looking at supporting some old style SOAP Web Service calls as well as Spring Integration. So to get off the ground I was looking at working with the example for producing a web service (http://spring.io/guides/gs/producing-web-service/) and adding spring integration into the mix.

When I did this though and try to hit the WSDL location I am now seeing this stack trace :

2014-09-22 09:53:17.823 ERROR 15188 --- [nio-8080-exec-1] a.c.c.C.[.[.[.[messageDispatcherServlet] : Servlet.service() for servlet[messageDispatcherServlet] in
 context with path [] threw exception [Request processing failed; nested exception is java.lang.AbstractMethodError: org.apache.xerces.dom.DeferredDocumentImpl.getXmlStandalone()Z] with root cause

        at org.springframework.ws.transport.http.WsdlDefinitionHandlerAdapter.handle(WsdlDefinitionHandlerAdapter.java:144)...

Looking around this looks to be related to the Xerces implementation that is pulled in for Integration. You can reproduce this by taking the example Producing a SOAP web service and changing the dependency section to look like this :

dependencies {
    compile("org.springframework.boot:spring-boot-starter-ws")
    compile("wsdl4j:wsdl4j:1.6.1")
    jaxb("com.sun.xml.bind:jaxb-xjc:2.2.4-1")
    compile(files(genJaxb.classesDir).builtBy(genJaxb))
    compile("org.springframework.boot:spring-boot-starter-integration")
}

Basically adding compile("org.springframework.boot:spring-boot-starter-integration") and then try hitting the WSDL at http://:/ws/countries.wsdl. (running gradle bootRun)

Now arguably this may not be the best way to do this and maybe I should just look to spring integration to expose the endpoint, but has anyone else seen and dealt with this?

Thanks in advance

Looks like for the WSDL generation you should provide this dependency:

compile "org.apache.ws.xmlschema:xmlschema-core:2.1.0"

Which is optional from the Spring WS and looks like there is no appropriate implementation in your environment.

UPDATE

Try to add xalan too:

compile "xalan:xalan:2.7.1"

Or do some tricks with Xerses: java.lang.AbstractMethodError: org.apache.xerces.dom.ElementImpl.getTextContent()Ljava/lang/String
