Re: [jersey-dev] [External] : support request for using ApacheConnectorP

[Jan Supol <jan.supol@xxxxxxxxxx>]

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

Subject: [External] : [jersey-dev] support request for using ApacheConnectorProvider to connect via proxy

 

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)

	org.glassfish.jersey.client.JerseyInvocation$Builder.method(JerseyInvocation.java:437)

TIA for any suggestion
