Weblogic 12.1.3 + JAX-RS 2 + jersey multipart - jax-rs

Question

I have a server Weblogic 12.1.3, with JAX-RS 2.x installed as a shared library (see e.g. https://docs.oracle.com/middleware/1213/wls/RESTF/use-jersey20-ri.htm#RESTF297). This shared library includes e.g. javax.ws.rs-api-2.0.jar and jersey-media-multipart-2.5.1.jar.
Please notice I am not sure that my webapp is really using this shared library, or it is using the standard JAX-RS 1.x library.
Now I want to upload files in multipart/form-data format, so I guess I need to add this dependency on my project:
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.5.1</version>
<scope>provided</scope>
</dependency>
However, the deploy fails, with error:
java.lang.ClassNotFoundException: org.glassfish.jersey.media.multipart.FormDataContentDisposition
So, I thought I could put my own library within my webapp:
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>2.5.1</version>
</dependency>
In this second case, the deploy fails with the following error:
java.lang.ClassNotFoundException: org.glassfish.jersey.ExtendedConfig
Any idea? Thank you.

At last, I got it work. I was missing both configuration in weblogic.xml and web.xml (I didn't know it was necessary web.xml).
Weblogic.xml:
<wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.9/weblogic-web-app.xsd">

Web.xml:
<servlet>
<servlet-name>JAX-RS</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer
</servlet-class>
<init-param>
<param-name>javax.ws.rs.Application</param-name>
<param-value>mypackage.jaxrs.JAXRSApplication
</param-value>
</init-param>
<init-param>
<param-name>jersey.config.server.provider.classnames</param-name>
<param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature
</param-value>

<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>JAX-RS</servlet-name>
<url-pattern>/v1/*</url-pattern>
</servlet-mapping>
Notice in particular the reference to MultiPartFeature.
Edit
As I thought, the web.xml is not necessary. You can put all the properties inside the Application class. The configuration above is more or less equivalent to the following
#ApplicationPath("/v1")
public class JAXRSApplication extends Application {
#Override
public Map<String, Object> getProperties() {
Map<String, Object> properties = new HashMap<>();
properties.put("jersey.config.server.provider.packages", "mypackage");
properties.put("jersey.config.server.provider.classnames",
"org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature");
return properties;
}
}
