org.glassfish.jersey.internal.RuntimeDelegateImpl NOT FOUND

Question

I am using jersey for my project and tring to parse a URI from a string.

UriBuilder.fromUri(\"http://localhost:8000\").build();

The code is

Answer 1

tl;dr if you're using jersey-client 1.x within an app that has a "provider" class also present, and you have rs-api-2.1.jar there, you need to add jersey-server 1.x or remove rs-api-2.1 if you happen to also have jsr311-api-1.1.1 present.

Appears this is what is happening:

Apparently jersey-client, when it is first coming up, tries to create a "mime map" of different mime types.

jersey-core 1.x ContextResolverFactory:

  public void init(ProviderServices providersServices, InjectableProviderFactory ipf) {
    Map>> rs = new HashMap();
    Set providers = providersServices.getProviders(ContextResolver.class);
    Iterator i$ = providers.iterator();

    while(i$.hasNext()) {
      ContextResolver provider = (ContextResolver)i$.next();
      List ms = MediaTypes.createMediaTypes((Produces)provider.getClass().getAnnotation(Produces.class));
       ...

So if there are any "providers" kicking around (ex: @Produces ({MediaType.WILDCARD})), it tries to lookup their type and add it to the mime type lists. However, it does it the following:

if you have rs-api-2.1.jar:

 private static RuntimeDelegate findDelegate() {
   try {
Object delegate = FactoryFinder.find("javax.ws.rs.ext.RuntimeDelegate", "org.glassfish.jersey.internal.RuntimeDelegateImpl", RuntimeDelegate.class);

If you have the following other dependency, it appears to implement it slightly differently:

jsr311-api-1.1.1.jar:

 private static RuntimeDelegate findDelegate() {
   try {
     Object delegate = FactoryFinder.find("javax.ws.rs.ext.RuntimeDelegate", "com.sun.ws.rs.ext.RuntimeDelegateImpl");

Jersey 1.x client happens to provide ./jersey-client-.19/com/sun/ws/rs/ext/RuntimeDelegateImpl.class

Whereas Jersey 1.x server provides:

./jersey-server-1.19/com/sun/jersey/server/impl/provider/RuntimeDelegateImpl.class

jersey 2.0 is "org.glassfish.jersey..." and provides "org.glassfish.jersey.internal.RuntimeDelegateImpl" (apparently sanely)

So it appears to me that rs-api-2.1 basically targets jersey 2.x by default. But happens to work with jersey-client 1.x if you also include jersey-server.

With jersey 2.x you don't need to include the "server to use the client" in such a weird way, seems to just work.

My hunch is either the API changed (you're not supposed to combine jersey 1.x with jsr-2? huh?), or maybe accidental flub, or bug, or poor design of jersey-client 1.x, who knows.

Adding things that happen to add "jersey 2.x" or "jersey-server 1.x" transitively also works.

These worked around the following runtime failure:
