Re: [jetty-users] Migrating 9 to 10: what replaces WebSocketServlet and

[Joakim Erdfelt <joakim@xxxxxxxxxxx>]

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<String, String> myMap = (Map<String, String>) json.fromJSON(str);

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<String, String> myMap = (Map<String, String>) 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
