Jersey 2.25.1 had working with Apache Client 4.5, but not properly with 4.5.1+. There were some changes in the Apache HTTP Client that caused us troubles when fixing it later. From the top of my head I do not remember if there were just certain cases (SSE)
which did not work or it did not work at all. But I would not go beyond HTTP Client 4.5.
The same with Jetty (client). Jersey 2.x supports Jetty 9, 3.0.x Jetty 11, and Jetty 12 is supported just by the latest Jersey 3.1.x/4.0.
Also, JDK 9+ is not tested with Jersey 2.25.1. I am sure Jersey server 2.25.1 does not work with JDK 9+, not sure about the client.
For the ClassNotFound/NoClassDefFound the java -Xdiag or java -verbose:class can give more hints about what is going on if some hidden issue.
If you have a reproducer, feel free to file an issue to GitHub Jersey issue tracker.
Hi Jan, thanks for your quick polite and sensible answer.
First of all I have already tried stackoferlow searching for a solution and also asking for my specific issue but I have go no answer so far.
Second I'm not starting a project really but I have to develop a web service client that will be used in an already existent web application that has its own dependencies and in particular there is already another jersey client implemented with jersey 2.25.1
I have your same concerns, of course.
I had also tried Jersey 2.45 but I encountered the same issue.
With respect to your observation about
Second, this NoClassDefFoundError you likely get because there are no Apache dependencies on your classpath. The jersey-apache-connector is just a bridge between JAX-RS/Jersey and the Apache HTTP client.
This is what I understood from documentation so I had already tried to add
httpclient-4.5.14.jar
to the WEB-INF/lib directory but to no avail
I tried also using the jersey-jetty-connector-2.25.1 coupled with jetty-client-12.0.4.jar
Also in this case I get a
java.lang.NoClassDefFoundError
on another class of course.
So it seems there is a class loading issue
I'm using Apache Tomcat 9 and JDK 8.

Hi,
First of all, I'd like to discourage you from starting with Jersey 2.25.1 which is from 2016, i.e. 8 years old now. Chances are that once something does not work for you, it has been fixed within these 8 years.
Second, this NoClassDefFoundError you likely get because there are no Apache dependencies on your classpath. The jersey-apache-connector is just a bridge between JAX-RS/Jersey and the Apache HTTP client.
Within those 8 years, Apache also stopped developing the Apache 4 HTTP Client and they now work on Apache 5 HTTP Client, which is supported by Jersey jersey-apache5-connector module. While your question sound like you are starting a project, you may think
about using the more modern Apache 5 HTTP client. Of course. the old Apache 4 HTTP Client can still be used with the jersey-apache-connector.
If you have any further question, you may also consider asking on Stack Overflow, which has more audience than Jersey mailing list. Also, you may use Jersey issue tracker on GitHub.
Hope this helps,
Jan
Hi, I guess this is not the appropriate place to post this request but I have not been able to find the right place.
So please if the request is not appropiate point me to the right place.
I have a Jersey client properly working but I'm struggling to use it to connect via a proxy.
Using documentation
https://eclipse-ee4j.github.io/jersey.github.io/documentation/latest/user-guide.html#client
and stackoverflow I have been led to guess that I have to use ApacheConnectorProvider
So I have added to the configuration of the client these two lines
configuration.connectorProvider(new ApacheConnectorProvider());
configuration =
configuration.property(ClientProperties.PROXY_URI,
"localhost:8000");
(I need proxy for debugging purposes, not production)
Of course I have added
jersey-apache-connector-2.25.1.jar
to the classpath.
When I run the client I get this exception
java.lang.NoClassDefFoundError: org/apache/http/protocol/HttpContext
org.glassfish.jersey.apache.connector.ApacheConnectorProvider.getConnector(ApacheConnectorProvider.java:115)
org.glassfish.jersey.client.ClientConfig$State.initRuntime(ClientConfig.java:425)
