How to solve java.lang.IllegalStateException: server in wrong condition Exception

Question

I am trying to deploy a quiet web service in a main Java project (swing application). I am using jersy for this. I searched a lot of sites on google, but I can not find the reason for this addition.

public class Main { 
public static void main(String[] args) throws Exception{        
    ResourceConfig resourceConfig = new ResourceConfig(MyResource.class);
    URI baseUri = UriBuilder.fromUri("http://localhost/").port(10049).build();

    HttpServer server = JdkHttpServerFactory.createHttpServer(baseUri,resourceConfig);
    server.start();
    System.out.println("Press Enter to stop the server. ");
    System.in.read();
    server.stop(0);
}
}


@Path("/hello")
public class MyResource {

// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
    return "Hello Jersey";
}

// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
    return "sdasd";
}

// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
    return "dsdfd";
}
}

An exception:

 Exception in thread "main" java.lang.IllegalStateException: server in wrong state
at sun.net.httpserver.ServerImpl.start(ServerImpl.java:139)
at sun.net.httpserver.HttpServerImpl.start(HttpServerImpl.java:58)
at org.glassfish.jersey.jdkhttp.JdkHttpServerFactory$2.start(JdkHttpServerFactory.java:363)

Maven:

<dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-jdk-http</artifactId>
        <version>2.22.1</version>
    </dependency>

How to resolve the above exception.

Answer 1

This issue is resolved by removing the server.start () line;

Line JdkHttpServerFactory.createHttpServer (baseUri, resourceConfig); creates an HTTP server and also starts the server.

" " ", .
