Please add as a comment to the existing issue. The issue you raised turned out to be of a larger scope, as the current proxy module is for forward proxies, not reverse proxies. We plan to be more explicit about these modules and document them in Jetty 10. -- Simone Bordet --- Finally, no matter how good the architecture and design are, to deliver bug-free software with optimal performance and reliability, the implementation technique must be flawless.

Re: [jetty-users] Migrating 9 to 10: what replaces WebSocketServlet and JSON.parse() ?
Jetty 10 still has the concept of a WebSocketServlet.
But it's no longer generic and functions for all implementations/apis.
With that said, you appear to be using the Jetty implementation/apis.
So, switch to `org.eclipse.jetty.websocket.server.JettyWebSocketServlet`
instead.
Found in websocket-jetty-server.jar
See:
https://search.maven.org/search?q=fc:org.eclipse.jetty.websocket.server.JettyWebSocketServlet
JSON classes were moved out from jetty-util to jetty-util-ajax back in
Jetty 9.0.0
You can find it at `org.eclipse.jetty.util.ajax.JSON`
See: https://search.maven.org/search?q=fc:org.eclipse.jetty.util.ajax.JSON
Note: that the static method JSON.parse(String) doesn't exist in Jetty 10.
The static methods on JSON couldn't handle the various configurations for
collections/maps/lists/pojos etc.
And the error messages were woefully inadequate as a result.
So you'll need to change your usage a small bit.
The closest usage would be ...
JSON json = new JSON();
// configure json here
Map myMap = (Map) json.fromJSON(str);

Re: [jetty-users] How to use Jetty ProxyServlet for reverse proxying?
Since BalancerServlet has rewriteTarget implemented, it seems a workaround would be to use this with a single member. I was experimenting with that and found a minor bug: if there are no members defined it gives a divide by zero error. (I expected something along the lines of "no balancer members defined"). Adding a member via setInitParameter balancerMember.a.proxyTo and it then starts proxying. However, there's a more significant issue: given a servletMapping of /proxy/* a request to http://localhost:8080/proxy/ is sent to http://localhost:8081/proxy/ - I expected it would go instead to http://localhost:8081/ - i.e. that the servletMapping would be removed. If the inclusion of servletMapping is deliberate (or can't be fixed without breaking backwards compatibility), then a parameter to explicitly exclude it would be useful. Should I add the above as comments to 6678, raise as distinct issue(s), or something else? ___ jetty-users mailing list jetty-users@eclipse.org To unsubscribe from this list, visit https://www.eclipse.org/mailman/listinfo/jetty-users
[jetty-users] Migrating 9 to 10: what replaces WebSocketServlet and JSON.parse() ?
Hello,
I am trying to migrate a war servlet from 9.4.43.v20210629 to 10.0.6 and
have read
https://www.eclipse.org/jetty/documentation/jetty-10/programming-guide/index.html#pg-migration-94-to-10
But unfortunately I still have questions - in my servlet I have:
public class MyServlet extends WebSocketServlet {
@Override
public void configure(WebSocketServletFactory factory) {
mLanguage = System.getenv("COUNTRY");
mBundle = ResourceBundle.getBundle("strings",
LOCALES.get(mLanguage));
factory.getPolicy().setIdleTimeout(IDLE_TIMEOUT_SECONDS * 1000);
factory.getPolicy().setMaxBinaryMessageSize(0);
factory.getPolicy().setMaxTextMessageSize(64 * 1024);
factory.register(MyListener.class);
factory.setCreator(new MyCreator(this,
mBundle.getString(STR_DATABASE_URL)));
}
@Override
protected void doGet(HttpServletRequest httpReq, HttpServletResponse
httpResp) throws ServletException, IOException {
//
}
}
What is the class to use in Jetty 10 instead of WebSocketServlet?
Also, I use the following code in few spots to parse JSON strings:
Map myMap = (Map) JSON.parse(str);
but now I get the compile error: String cannot be converted to Source
Is there a new parser, should I maybe use AsyncJSON and how?
Best regards
Alex
