Hello World with Jersey and Grizzly (from User Guide)
I'm looking at the Jersey User Guide and trying to set up a Hello World example using a Jersey web service and an embedded Grizzly server.
I'm running through Section 1 "Getting Started". I've got the code example in section 1.1 compiling just fine:
// The Java class will be hosted at the URI path "/helloworld"
@Path("/helloworld")
public class HelloWorldResource {
// The Java method will process HTTP GET requests
@GET
// The Java method will produce content identified by the MIME Media
// type "text/plain"
@Produces("text/plain")
public String getClichedMessage() {
// Return some cliched textual content
return "Hello World";
}
}
But then I get to section 1.2, "Deploying the Root Resource", which is where I'm supposed to set up an embedded Grizzly web server to test my resource with:
public class Main {
public static void main(String[] args) throws IOException {
final String baseUri = "http://localhost:9998/";
final Map<String, String> initParams =
new HashMap<String, String>();
initParams.put("com.sun.jersey.config.property.packages",
"com.sun.jersey.samples.helloworld.resources");
System.out.println("Starting grizzly...");
SelectorThread threadSelector =
GrizzlyWebContainerFactory.create(baseUri, initParams);
System.out.println(String.format(
"Jersey app started with WADL available at %sapplication.wadln” +
“Try out %shelloworldnHit enter to stop it...", baseUri, baseUri));
System.in.read();
threadSelector.stopEndpoint();
System.exit(0);
}
}
The problem is, it seems this user guide has not been updated in awhile and the class GrizzlyWebContainerFactory no longer exists!
I'm using Jersery v 1.10 and Grizzly v 1.9.41.
Can someone help me recreate this example? I know I can run the web service in a container, I'm interested in running it via the simplest possible embedded server setup that requires no additional resources (web.xml, etc.) in my project, just the 2 classes.
I think the answer is that I need to include the jersey-grizzly dependency, then I can follow along as per the user guide.
This is NOT specified in the list of required dependencies the user guide provides:
Non-maven developers require:
grizzly-servlet-webserver.jar, jersey-server.jar, jersey-core.jar, jsr311-api.jar, asm.jar
