Yesterday I got a post comment about some problems with running CXF JAX-RS on Apache Tomcat. But also 2 weeks ago Apache TomEE 1.0 has been officially released. I decided to rework the example without using Spring (which was causing the problems with JAX-RS) and deploy it to TomEE.
My project was based on the original one from this post (published over 3 years ago! April 2009): Dveloping RESTful Web Services using Apache CXF and Maven2.
Updating the original project
I decided to get rid of Spring from my project and to use Apache TomEE Plus (TomEE with additional OpenEJB and CXF jars) to manage my rest service.
To build JavaEE 6 web application I decided to use new Codehaus MOJO archetype. Instead of webapp-jee5 I used newer webapp-javaee6 archetype.
From CXF dependencies I only copied cxf-rt-frontend-jaxrs and updated its version from 2.1.4 to 2.5.2. Also I changed its scope to provided (as CXF is shipped with TomEE Plus).
After I copied and pasted my old code I changed @ProduceMime to @Produces (by the time I wrote my previous post JAX-RS was not final yet).
Setting up TomEE Plus and running the application
I downloaded TomEE Plus (with CXF-powered JAX-WS and JAX-RS runtime). Then, in Eclipse, I added new Tomcat 7 server and pointed it out to TomEE installation directory (TomEE is fully compatibile with Tomcat 7). Next I ran the application, but got the following exception:
Caused by: java.lang.IllegalArgumentException: Unresolved variables; only 0 value(s) given for 1 unique variable(s) at org.apache.cxf.jaxrs.impl.UriBuilderImpl.substituteVarargs(UriBuilderImpl.java:185) at org.apache.cxf.jaxrs.impl.UriBuilderImpl.doBuild(UriBuilderImpl.java:82) at org.apache.cxf.jaxrs.impl.UriBuilderImpl.build(UriBuilderImpl.java:75)
After a quick playing around it turned out that name path param cannot be defined at the class level. I moved this definition to the first method and added @Path("/greetings") to the class.
I restarted the application and all worked like a charm.
To test I opened the following links in my browser:
http://localhost:8080/cxf-jax-rs-example/greetings/name/lukasz http://localhost:8080/cxf-jax-rs-example/greetings/name/lukasz/state/poland http://localhost:8080/cxf-jax-rs-example/greetings/name/lukasz/state/poland/test1/test2/test3And this time no Spring configuration at all! TomEE and JavaEE 6 rock!
The source code is here: https://github.com/lukasz-budnik/cxf-jax-rs-example.
There is also one point to note. TomEE is insanely fast!
