Niall,

Thanks for your response.  I can see from the source code that 
ActiveService always spawns a new thread, obviously it would be better 
to make use of a thread pool, but that should be a pretty simple 
change.  It's not obvious how the IO layer knows when the service's 
response is complete; the Thread isn't visible, so you can't join() it, 
and there's no FutureResult or similar handle for polling...

OK, never mind, I just found the OutputMonitor. :)  Interesting design 
choice to have the OutputStream drive the completion.  So it looks like 
I could give the Request and Response to some other thread and have the 
Service's thread forget about them entirely--the IO layer would detect 
when the response was considered to be complete and adopt the response 
(carrying its socket in tow) at that point.

[Enrique R. <ero...@ap...>]

Hi, Niall,

I've been thinking for some time that you ought to check out "MINA," a 
NIO framework gaining widespread adoption at Apache.  We currently have 
teams working on LDAP, Kerberos, DNS, DHCP, NTP, SMTP, and IMAP, as well 
as SSL, SASL, and other filter support.

http://directory.apache.org/subprojects/network/index.html

There's some super-basic HTTP example code at the bottom of that page 
that might give you a quick idea of how it works.

[Niall G. <gal...@ya...>]

Hi Alex,

Look at simple.http.load.ActiveService, it does
exactly what you want. In response to your last
question, I think that offloading the back-end IO to a
non-blocking system would be a win. I see no
difference in a proxy acting as a client versus a
non-proxy server. If you reverse the processing
technique used by Simple I think you would have a very
efficient proxy server. I have thought about such a
proxy server in the past, however I have not had time
to implement it even though I am sure you could modify
simple.http.* to achieve it.

Hope this helps,
Niall

[Simpleweb-Support] Disconnect processing thread from request/socket?

[Alex C. <al...@cl...>]

Hi there,

According to my cursory research on the subject, asynchronous IO is not 
seen as a huge win for Java servlet environments, since any given thread 
is generally either waiting in the pool doing nothing or fully utilized 
servicing a  servlet request.  The only exception I've seen general 
agreement on is that a large number of sockets in the keepalive state 
can be efficiently handled using a smaller number of threads.

On the other hand, I'm working on a proxy server that effectively pauses 
a request thread for 5-500 milliseconds while a backend server does its 
own processing.  It would be great if I could somehow take those backend 
sockets off the request processing threads' "hands" and have maybe a 
handful of dedicated backend IO threads sending the backend requests, 
waiting for their responses and receiving them.

So what I'd need would be a way to drop a given request (with its 
associated socket) from the current processing thread, and pick it up 
later on.

While I'm sure I can accomplish this using a "raw" NIO implementation, 
I'm keen to stand on the shoulders of giants.  Is there anything 
resembling what I'm looking for in Simple?  If not, would it be a major 
challenge to add it?  And last but certainly not least, am I way 
off-base in my assertion that offloading the back-end IO to a 
non-blocking system would be a win?

Thanks,

Re: [Simpleweb-Support] Retrieving files from jar files

[Niall G. <gal...@ya...>]

Hi Luce,

I think there are several ways to do this, the
cleanest of these would be to use the java.util.jar
package to examine the contents of the Jar file before
locating and extracting the gif image. This is what
the Velocity JarResourceLoader uses. I think it would
go somting like this:

String target = request.getURI();

JarInputStream file = new JarInputStream("site.jar");

while(...){
   JarFileEntry entry = file.getNextJarEntry();

   if(entry.getName().equals(target)){
      file.read(buffer, 0, size);
   }
}

That should allow you to read a resource from any Jar
file. However, this would almost certainly require a
cache if you are going to implement such a Service.
Have a look at simple.util.cache.Cache.

Also, you might like to try exploding the Jar file
into a temporary directory. This is what Tomcat and
other Servlet engines do with War files. 

Finally, I thing this should work:

ClassLoader loader = new URLClassLoader(new
File("site.jar").toURL());

InputStream stream =
loader.getResourceAsStream("image.gif");

Hope this helps.

[Simpleweb-Support] Retrieving files from jar files

[Luce C. <lu...@se...>]

Hi,

I was wondering if it is possible to use simpleweb to retrieve files 
located within a jar file.

I have a jar file (site.jar) which contains numerous .html and .gif 
files. I am able to retrieve the .html files (using VelocityTemplate) 
but cannot work out how to retrieve the .gif files.

Any help would be appreciated.

Regards

Luce

Well, the implementation itself is quite different as the underlying=20
language and VM are very much different. That said, I think that=20
conceptually they are very close. Or to put it another way, Simple is=20
very much the inspiration for LuaWeb :)

Both Simple and LuaWeb provides 3 main functionalities as I see it: an=20=

event dispatcher, a core HTTP engine and the scaffolding for an app=20
server.

Concurrent event dispatching in Lua is handled quite differently than=20
in Simple as Lua provides coroutine instead of threads:

"Non-Preemptive Multithreading"
http://www.lua.org/pil/9.4.html

The end result being somewhat similar to java.nio selectors as well as=20=

what Simple itself does: limit the number to threads while keeping=20
concurrency high nonetheless.

The HTTP engine itself is quite similar in both implementation:=20
requests, responses, services, etc. In both libraries, an HTTP engine=20
is defined as a set of services which handle a subset of the URL=20
namespace.

Finally, there is the app server scaffolding. This is perhaps where=20
Simple and LuaWeb diverge the most. But this is somewhat to be expected=20=

as everyone has their own like and dislike about how an app server=20
should behave. Even ZO=CB, while happily using Simple since the summer =
of=20
2003, has its own implementation of an app server build on top of=20
Simple itself...

Perhaps one thing which would be beneficial though, is to have the=20
Simple HTTP engine emphasize the HTTP methods themselves (e.g. GET vs=20
HEAD vs OPTIONS, etc).

For example, in LuaWeb, the default HTTP service implements HEAD in=20
terms of GET. That way all the services can handle a HEAD request=20
out-of-the-box. In contrast, each Simple services has to explicitly=20
switch between the different HTTP methods in their process() method. As=20=

an illustration, contrast the implementation of=20
simple.http.serve.FileResource and LWFileService:

http://dev.alt.textdrive.com/file/LW/LWFileService.lua

The same applies for OPTIONS which is implemented by the default=20
LWService in terms of what HTTP methods a service effectively provides.

Emphasizing the HTTP methods upfront provides a nice logical=20
distinction between what your custom service needs to do, as there is=20
no need for conditional execution (e.g. GET vs POST vs DELETE).

Most likely there are other differences here and there, but, all in=20
all, I found both library quite similar in purpose if not in execution=20=

RE: [Simpleweb-Support] Howto use PatternMapper?

[Henry V. <hen...@ge...>]

Hi andy

i had the same problem a while ago.

the solution is to implement a custom mapper and then configure it. Or
extends it and when the custom files then redirect to the good class

ex.
 MyCustomMapper implements mapper
 override or implement the getClass(String target)

Then

      System.setProperty("simple.http.load.mapper", "com.MyCustomMapper");
	MapperEngine engine = new MapperEngine();
	Connection connection = ConnectionFactory.getConnection(engine);
	connection.connect(new ServerSocket(8080));

I am currently using the following code to run a simple test server:

Re: [Simpleweb-Support] Trying to use Simple 2.4.2 on gij (GNU Classpath)

[Andy M. <and...@ya...>]

I thought it might be a problem in gij, but I get the same error under
sablevm, which is supposed to be very good. I thinking that the problem
might be in classpath. I just realised that that this error sometimes
happens under gij, too (when this error occurs, IllegalMonitorState
doesn't).
java.lang.NullPointerException
   at simple.util.schedule.SchedulerQueue.dequeue (SchedulerQueue.java)
   at simple.util.schedule.Scheduler.dequeue (Scheduler.java:183)

   at java.lang.Thread.callRun (Thread.java:391)
   at java.lang.VirtualMachine.runThread (VirtualMachine.java:137)

Note that the error comes from the same method, it definetely looks
like a threading problem, but that doesn't mean the problem is in
Simple. I'l try 2.5.4.

Re: [Simpleweb-Support] Trying to use Simple 2.4.2 on gij (GNU Classpath)

[Niall G. <gal...@ya...>]

Hi,

Strange exception, ill have a look at it in more
detail. If you want to download 2.5.4 then go to the
following URL:

http://simpleweb.sourceforge.net/download

I am no longer using the SF download feature as it
requires the use of SSH and FTP.

My guess is that this is a problem with gij as the
Scheduler is quite heavily tested and has worked since
java 1.2.x. Also the Scheduler is fully thread safe.

[Simpleweb-Support] Trying to use Simple 2.4.2 on gij (GNU Classpath)

[Andy M. <and...@ya...>]

I'm trying to run a basic demo server using Simple on gij 3.4 (Debian
Sid BTW).

Here's the code I'm using:
import simple.http.connect.*;
import simple.http.serve.*;
import simple.http.load.*;
import java.net.*;

public class TestServer {

	public static void main(String[] list) throws Exception {
		MapperEngine engine = new MapperEngine(new FileContext(),new
java.io.File(".").getCanonicalFile(), null);
		Connection connection = ConnectionFactory.getConnection(engine);
		connection.connect(new ServerSocket(8080));
	}
}

Note that the MapperEngine constructor call had to be changed b/c of an
apparent quirk in java.io.File in classpath. When I run this and try to
get my browser to connect I get:
java.lang.IllegalMonitorStateException
   at simple.util.schedule.Scheduler.dequeue (Scheduler.java:183)
   at simple.http.Processor.execute (Processor.java:110)
   at simple.http.Processor.run (Processor.java:77)
   at java.lang.Thread.run (Thread.java:705)
   at java.lang.VMThread.callRun (VMThread.java:119)
   at java.lang.Thread.callRun (Thread.java:391)
   at java.lang.VirtualMachine.runThread (VirtualMachine.java:137)

I tried to download Simple 2.5.4, but it doesn't seem to be on SF??

Hi,

I have had a look at you implementation in LUA. Just
wondering, you have taken a different approach on a
few things, any ideas you think might be useful in
Simple?

Talking of which, albeit slightly off-topic, I'm somewhat=20
re-implementing simple-core in Lua [1].

Here is a brief illustration:

-- create the application server
local anApplication =3D LWApplication.new( "*", 1080 )

-- register a service
anApplication.registerService( LWDirectoryService.new( "/prefix/",=20
"/Directory/Path" ) )

-- start the application
anApplication.start()

As easy as 123 :)

If you are interested in perusing a full blown application which uses=20

[Simpleweb-Support] simple server, mamba

[sszretter <ssz...@ho...>]

I am interested in using the Simple engine to serve pages and 
objects, but need a starting point.  I checked out the mamba engine 
that uses Simple, but it uses version 2.4 of Simple.   Mamba is 
probably acceptable if it could use the latest Simple, OR maybe 
someone has another suggestion??

I am mainly interested in creating a stand alone java app that serves 
up static pages and images from the hard disk, as well as objects 
that produce html output.  Simple sounds like it does this, but is 
for me just missing the stand-alone app framework...

Re: [Simpleweb-Support] bad addresses from Request.getInetAddress()

[Niall G. <ni...@em...>]

Hi David,

As far as the implementation of Simple goes, the InetAddress is acquired fr=
om the Socket.getInetAddress. There are no modifications and I am pretty su=
re that it works correctly. It might be worth you while writing a ProtocolH=
andler that dumps the HTTP messages to a file, this way you can check to se=
e if a proxy is being used.=20

RE: [Simpleweb-Support] How to pass information to BasicService?

[Henry V. <hen...@ge...>]

Ok found out how....

 extends ReflectionService

and have custom prepare method

   public void prepare(CustomContainer container)
   {
      logger.debug("hello world " + container );
   }

when the engine is prepared
  MapperEngine engine = new MapperEngine(new FileContext(),new
CustomContainer());

A+

hi Cristophe.
Thanks for answering.

Im more interested in the first answer. But Where do you instanciate your
custom context to pass it in the prepare?
Wich class is the one i have to implement for the interception and how to
configure it?

May be you can override the prepare method in BasicService
And use the passed Object.

public void prepare(LoaderEngine engine, Object data) {
      this.myContext = (MyContext) data;
}

public void process(Request req, Response resp) throws Exception {
   ...
   myContext.getXXX();
   ...
}

Or you can create a custom PipelineFactory and set some attributes:

public class CustomPipelineFactory extends BufferedPipelineFactory {

  // ============
  // Contructors
  // ============

  public CustomPipelineFactory() {
    super();
  }

  public CustomPipelineFactory(int size) {
    super(size);
  }

  // ===============
  // Public method
  // ===============

  public Pipeline getInstance(Socket sock) throws IOException {
    Pipeline pipe = super.getInstance(sock);
    // sets some attributes
    pipe.setAttribute("port", new Integer(sock.getPort()));
    pipe.setAttribute("localPort", new Integer(sock.getLocalPort()));
    pipe.setAttribute("socket", sock);
    ...
    return pipe;
  }
}

In your Service:

public void process(Request req, Response resp) throws Exception {
    Attributes attrs = req.getAttributes();
    int port = ((Integer) attrs.getAttribute("port")).intValue();
    int localPort = ((Integer) attrs.getAttribute("localPort")).intValue();
    ...
}

To set up simpleweb:

PipelineFactory pipelineFactory = new CustomPipelineFactory(bufferSize);
Connection network = ConnectionFactory.getConnection(myhandler,
pipelineFactory);
network.connect(new ServerSocket(port));
