MessageDispatcherServlet is not assignable to Servlet

[jevgenija.hozakova]

Hello,

I'm trying to create my first Spring WS according to Contract-First Web Services.
While defining servlet in web.xml I get undersign servlet-class with red error message ""MessageDispatcherServlet is not assignable to Servlet"
<servlet>
<servlet-name>spring-ws</servlet-name>
<servlet-class>org.springframework.ws.transport.http.Messag eDispatcherServlet</servlet-class>
<init-param>
<param-name>transformWsdlLocations</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

I'm looking a lot throught internet, and find nothing about this error. Please help what is the prob

and while I'm trying to start application I'v got exception

Thank you.

The error you've mentioned may occur when you have servlet-api.jar in your WEB-INF/lib.
But the real problem (from the logs you've provided) seem to be:

        Provider com.sun.xml.stream.ZephyrParserFactory not found

Yes, I see, but it dont help me. I think the problem is in configuration. But I dont know what is the problem

Just in case, you probably need to add the dependency on the sjsxp which contains the com.sun.xml.stream.ZephyrParserFactory.
The sjsxp is : Sun Java Streaming XML Parser, the implementation of JSR 173

With maven, you can found the lib with something like :
<dependency>
<groupId>com.sun.xml.stream</groupId>
<artifactId>sjsxp</artifactId>
<version>1.0.2</version>
</dependency>
