• org.apache.wink.common.model.atom.AtomEntry. For more information about integrating JAX-RS 2.0 with Atom, see JAX-RS 2.0 integration with Atom.
• org.apache.wink.client.handlers.BasicAuthSecurityHandler. If you want to use basic authentication in JAX-RS 2.0, see the following code snippets:
  1. Use ClientRequestFilter through the JAX-RS 2.0 standard Client API as shown in the code example:

     import java.io.IOException;
     import java.io.UnsupportedEncodingException;
     import javax.ws.rs.client.ClientRequestContext;
     import javax.ws.rs.client.ClientRequestFilter;
     import javax.ws.rs.core.MultivaluedMap;
     import javax.xml.bind.DatatypeConverter;
     
     public class BasicAuthFilter implements ClientRequestFilter {
     
         private final String usr;
         private final String pwd;
     
         public BasicAuthFilter(String usr, String pwd) {
             this.usr = user;
             this.pwd = pwd;
         }
     
         public void filter(ClientRequestContext requestContext) throws IOException {
             MultivaluedMap<String, Object> headers = requestContext.getHeaders();
     
          String token = this.usr + ":" + this.pwd;
          final String basicAuthentication ="Basic " + DatatypeConverter.printBase64Binary(token.getBytes("UTF-8"));
          headers.add("Authorization", basicAuthentication);
         }
     }

  2. Register to the ClientBuilder:

     ClientBuilder cb = ClientBuilder.newBuilder();
     cb.register(new BasicAuthFilter("user","password"));

• org.apache.wink.client.handlers.LtpaAuthSecurityHandler. If you want to use the LTPA-based security client to secure downstream resources, see Configuring a resource to receive multipart/form-data parts from an HTML form submission in JAX-RS 2.0.
• org.apache.wink.server.internal.providers.exception.EJBAccessExceptionMapper. This API is no longer supported because it is the Wink-specified ExceptionMapper. You can define your own ExceptionMapper to map the EJBAccessException.
• com.ibm.websphere.jaxrs.server.IBMRestFilter. This API is no longer supported because it is based on Wink Filter.

1. Download the following files that can enable Wink Client in the JAX-RS 2.0 server run time.
   • Download the Apache Wink and related JAR files from http://wink.apache.org/downloads.html.
   • Download the Apache HTTP and related JAR files from http://hc.apache.org/.
   Note: If the JAX-RS 2.0 feature is not enabled, you must also download and add the JAX-RS API to the third-party lib. Download the JAX-RS API from https://jax-rs-spec.java.net/nonav/.
2. Save all JAR files into the <third-party lib> directory.
3. Add the location of <third-party lib> to the server.xml file:

   <library id="thirdPartyLib">
     <fileset dir=" <third-party lib>" includes="*.jar" scanInterval="5s"/>
   </library>
   <enterpriseApplication id="<Your Ear ID>" location="<Your Ear Name>" name="<Your Ear Name>">
     <classloader commonLibraryRef="thirdPartyLib"/>
   </enterpriseApplication>
