    Kalaibharathi,

    GWT Super Dev Mode is only responsible for client side code. org.eclipse.jetty.servlet.ServletHolder is a server class.

    Best regards

        Same problem. Serverclass that is not meant for feeding it to GWT. What are you staying to start? Your own existing project or the BuiltInDS sample? What IDE?

          In #1 you say „Compiling GWT application“, but the server log looks like you are starting super development mode.
          Do you want to develop and change-reload, which is what SuperDevMode is for or compile to package it and run later on the Webserver?

            IDE which we're using is Eclipse IDE for Java EE 2022-03. We are getting those errors after the launch of jetty server and i have attached the image of it. And we want to compile and run the application on the webserver.

              For compile and package and then run in your webserver you don't need Jetty. But you are using SuperDevMode, which is for developing. So your answer is not really clear.
              Is this an existing project or the BuiltInDS sample? If an existing project, why don't you try with BuiltInDS first and then search for differences in classpath, startup, etc?
              BuiltInDS with Eclipse and the GWT Eclipse Plugin is really straight forward.

                It is an existing maven project. Once we run "gwt:debug", we will get the following as the result.

                [INFO] --- gwt-maven-plugin:2.10.0:debug (default-cli) @ abc ---
                [INFO] starting debugger on port 8000 in suspend mode

                [INFO] Listening for transport dt_socket at address: 8000

                After this jetty server will be launched and then Super Dev Mode will start up.
                We are getting the below mentioned errors after this point

                [ERROR] java.lang.NoSuchMethodError: 'void org.eclipse.jetty.server.ServerConnector.setSoLingerTime(int)'

                [ERROR] java.lang.NoClassDefFoundError: org/eclipse/jetty/util/Trie

                [ERROR] java.lang.NoSuchMethodError: 'void org.eclipse.jetty.servlet.ServletHolder.<init>(javax.servlet.Servlet)'

                  Hi Kalaibharathi

                  I don't know about your project, but the root cause is that you tell Super Dev Mode, which is only for client side code, to also compile server side code.
                  Super Dev Mode turns your Java into Javascript. As you only need some JDK classes, it does not (and can not) compile everything. See here.

                  Read about Super Dev Mode on the GWT page and especially how you tell it what to compile/serve.
                  In the Super Dev Mode startup it should somewhere mention your .gwt.xml file.

                  Also try to compare your project to the BuiltInDS sample.

                  Best regards
