PI84036: JAX-RS Client must access endpoints via authenticating proxy

Fixes are available

APAR status

Closed as program error.

Error description

In some cases, users need to use the JAX-RS Client APIs to
access remote URL endpoints that must pass through an
authenticating proxy server.  An authenticating proxy server
is similar to a proxy server, but requires that the client
be given special authorization to access the remote
endpoints.  WebSphere Liberty has no mechanism for users to
specify Basic authorization credentials for authenticating
with a proxy server.

Problem conclusion

The fix for this APAR adds new configuration properties for the
JAX-RS Client that enables proxy authentication.  They are:
com.ibm.ws.jaxrs.client.proxy.username
com.ibm.ws.jaxrs.client.proxy.password

These properties must be used with existing proxy configuration
properties.  Here is an example of how these properties could be
used in JAX-RS Client API code:

ClientBuilder cb = ClientBuilder.newBuilder();
cb.property("com.ibm.ws.jaxrs.client.proxy.host", host); //
hostname or IP address of the proxy server
cb.property("com.ibm.ws.jaxrs.client.proxy.port", port);  // TCP
port for the proxy server
cb.property("com.ibm.ws.jaxrs.client.proxy.username", username);
// username of the user to
cb.property("com.ibm.ws.jaxrs.client.proxy.password",
password);
Client c = cb.build();
String response =
c.target(targetURL).request().get(String.class); // targetURL is
the remote endpoint that requires a proxy to access

The fix for this APAR is currently targeted for inclusion in fix
pack 17.0.0.3.  Please refer to the Recommended Updates page for
