Is Restlet application distributed ?
Hi All, We are going implement a application using Restlet. In this, We need a requirement like distributed system or mechanism. Our Restlet application having different components(modules) which needs to run on different servers(machines). For example, I have 3 different modules which are installed in different machines. In this, there is main module(other than above 3 modules) which needs to identify an incoming request and process the request to corresponding server(module). Could you please suggest me how do i setup to meet my requirement i.e. How to identify the routing for different servers. I would like to know whether Restlet supports or not? -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2703781
Restlet speed
Restlet does not seem to run as fast as I would expect. I was hoping someone
could point me how to get it running faster.
Looking at the examples, I've created a simple server:
import org.restlet.Server;
import org.restlet.data.Protocol;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;
public class SimpleServer extends ServerResource {
public static void main(String[] args) throws Exception {
// Create the HTTP server and listen on port 8182
new Server(Protocol.HTTP, 8182, SimpleServer.class).start();
}
@Get
public String toString() {
return hello, world;
}
}
I also have created a simple client:
import java.io.IOException;
import org.restlet.resource.ClientResource;
public class SimpleClient {
public static void main(String [] args) throws IOException {
// Create the client resource
ClientResource resource = new ClientResource(http://localhost:8182;);
// Write the response entity on the console
long startTime = System.nanoTime();
// If getMethod 1 is used, I get 3.12 seconds.
// Setting getMethod 2 results in 2.30 seconds.
int getMethod = 2;
for( int i=0; i 10; i++) {
if( getMethod == 1 )
resource.get().write(System.out);
else
new ClientResource(http://localhost:8182
).get().write(System.out);
}
long endTime = System.nanoTime();
System.out.println( (endTime-startTime) / 10.0);
}
}
If both are running on the same system, I get can process 10 requests in 2.3
or 3.1 seconds depending on the method used. I'm not sure why creating a new
client resource is faster than reusing the old one. At any rate, I was
hoping to run at least 100 in one second. Any thoughts on why this is slow?

Question about Complete Web Server
Hello Everyone, I am new to Restlets and the java Restful coding seen. I had a question about the Complete Web Server feature that is listed for the Restlet Framework. Is this build in web server enterprise or high traffic capable or do you need an implementation of Tomcat, Glassfish ect... to do something that would be getting high traffic or use?

RE: Restlet speed
Hi Paul,
If you are using version 2.0, I would suggest using one of the pluggable HTTP
connectors (“org.restlet.ext.net” or “org.restlet.ext.httpclient”) to get
production level performances. The internal/default connector is only intended
for development/test purpose or small loads). In version 2.1, we are radically
improving this connector though.
Let us know if this helps.
Best regards,
Jerome

RE: Question about Complete Web Server
Hi Jason, In version 2.0, there are two pieces you need for this : · The Directory class to serve static files · The Jetty or Simple pluggable connectors (not used as Servlet containers, but as standalone connectors) In version 2.1, our goal is to have an internal HTTP server that is as scalable as the connectors above. In term of references, we have been running http://www.restlet.org for years with this set-up without any trouble and know at least on large site (Overstock.com) using it in such configuration (see public presentation at JavaOne 2008).

catching parse exception using converter service
Hi! I'm using Restlet 2.0.4 with a converterService (Jackson). Problem is when I receive a Json object with a parse exception, it is not caught in the StatusService (which already works with any other exception that occurs within the resource) Example: WARNING: Unable to parse the object with Jackson. org.codehaus.jackson.map.JsonMappingException: Unrecognized field asd (Class com.example.ClassDTO), not marked as ignorable at [Source: org.restlet.engine.http.io.UnclosableInputStream@15e33df; line: 1, column: 2] I'd like to catch it in the StatusService to set the response with an error message.

Hello, I think that, for the moment, these kind of parsing errors are actually caught as unsupported media type error. Perhaps, this kind of exception should not be wrapped and hidden.

RE: Is Restlet application distributed ?
Hi Jerome, My Restlet application would have a common Gateway and the underlying functionality will be provided by different modules. For scalability reasons, different underlying modules will be hosted on different servers. Each server knows where different modules are hosted. So when the Gateway receives the request, based on the URL it knows which module will service the request and which server it needs to be routed to, based on the information it knows about which server is hosting which module. The sessions will also be managed commonly across all servers. So in order to make this routing possible, router.attach needs some kind of redirection to a different URL so that request ends up on correct server. Can you please help us on how to set this up in Restlet? Regards, Komara. -- http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447dsMessageId=2704198
