Generowanie wadl z istniejącej usługi odpoczynku CXF

Question

Próbuję uzyskać create a wadl from an existing CXF rest service. To nie działa. Otrzymuję zamiast HTTP 404. Usługa reszta sama działa. Używam Tomcat 7.

Co robię źle?

Answer 1

I had to add do zależności:

<dependency> 
    <groupId>org.apache.cxf</groupId> 
    <artifactId>cxf-rt-rs-service-description</artifactId> 
    <version>${cxf.version}</version> 
</dependency> 

Niestety, to się nie powiedzie, nie dając mi wyjątek, że czegoś brakuje na ścieżce klasy.

Ponadto, zgodnie z sugestią David J. Liszewski poprawny URL:

http://localhost:8080/cxf3example/services/example?_wadl

Answer 2

Usługa jest zadeklarowane jako "/" np.

Spróbuj http://localhost:8080/cxf3example/services/example?_wadl
