How to develop JAX-RS web services?

Question

Hi,
I am trying to build a REST web service using JAX-RS in OEPE 12.1 and WebLogic 12c. When I try to use annotations like javax.ws.rs.GET and javax.ws.rs.Path, I get a compilation error. Which JAR files available from the server runtime should I add to the build path?
I have read the JAX-RS development guide (http://docs.oracle.com/cd/E24329_01/web.1211/e24983/toc.htm). But it makes no mention of how to create a project in OEPE.
Thanks.

Hello,
A couple of options:
1. Create a Weblogic Web Service Project with 12c Runtime.
a. File->New->Web Service Project
b. Select your 12c runtime
-You should have a project with the JAX-RS on the java build library path.
2. Create a standard J2ee Project ie: Web Project
a. Create A Dynamic Web Project
b. Select your 12c runtime
c. Rt Click the Project->Properties->Java Build Path->Libraries->Add External JARs, then navigate and select "WLS 12c Dir"\modules\com.sun.jersey.core_"version".jar
This should allow the resolution of the javax.ws.rs.* annotations.
Additionally, you may need to rt. click the Deployment Descriptor of your project and select Generate Deployment Descriptor Stub. Subsequently add the following:
<servlet>
<servlet-name>JAX-RS Application</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JAX-RS Application</servlet-name>
<url-pattern>*</url-pattern>
</servlet-mapping>
