Re: [Simpleweb-Support] Docs?

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

Hi Brian, 

If you are talking about the MapperEngine then your
best bet is to download the demo. It has a configured
MapperEngine running. The Mapper.xml configuration has
two blocks, one is for loading Services and another is
for mapping those services to a path pattern. So for
example

<lookup>
   <service name="instance-name" type="class-name">
      <property key="some-key">some-value</property>
      <!-- etc.. as many properties as needed -->
   </service>
</lookup>

<resolve>
   <match path="/some/path/*" name="instance-name"/> 
</resolve>

Now when the mapper engine is asked for
/some/path/index.html it will load an initialize the
service named instance-name of type class-name. To see
this in action, its best to download the demo package
at:

http://www.simpleframework.org/download/

Hope this helps,
Niall

Re: [Simpleweb-Support] getParameterValues method on simple.http.Request

[Dennis W. <de...@gu...>]

Hi Niall,

I downloaded release 3.1 and release 2.7 and followed your advice about 
putting the insert(String, String) method back in.  I created a patch file 
enclosed.  Hopefully it's helpfull.  

The new class compiles and seems to work for basic cases.  I guess I have to 
access the list of values via Parameters String[] getParameters(String) 
method?  I have been using the convenience method Request String 
getParameter(String), so I will have to rewrite some to prove it works %100.

Thanks,


Dennis

Re: [Simpleweb-Support] How to shutdown th server

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

Hi,

Currently you only option is to add in your own
signalling implementation. Something like

public interface Receiver {

   public void handle(Signal signal);
}

And have the following objects receive events to stop
the threads they use:

PipelineProcessor
Connection
TimeCache

So something like Signaler.send(new MyStopSignal())
can terminate the server. I have been meaning to
implement this, just have not had the time.

[Simpleweb-Support] How to shutdown th server

[R P. <pat...@gm...>]

Hello,

Can somebody tell me how to shutdown a "simple" server ?
Obviously I don't want to talk about killing the job with a <CTRL>C.

Thank you.

Re: [Simpleweb-Support] Problem using the tutorial

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

Hi Vincent,

I would recommend you download the demo package from
simpleweb.sf.net/download. The problem you mention is
due to an error in the LoaderEngine.load method.

on line 283 the source shows

load(name, className)

it should show

load(name, className, new Object[]{})

The demonstration should be a little simpler to use,
than the tutorial, which is slightly out of date.

[Simpleweb-Support] Problem using the tutorial

[Vincent E. <vin...@gm...>]

Hello !

I'm trying to have the DemoServer and the HelloService from the tutorial
working, but I'm lost. If I copy/paste the code from the tutorial, the
server runs, but I always get a 404 error, whatever url I try.

I tried to load and link manually the HelloService to a specific URL, but
doing this the DemoServer doesn't even run : it crashs and throws this :

Exception in thread "main" java.lang.StackOverflowError
   at simple.http.load.LoaderEngine.load(Unknown Source)
   at simple.http.load.LoaderEngine.load(Unknown Source)
   ....

What does it mean ?

Does anybody have a basic example of a server and a service that works ?
Thanks a lot for any help ! And sorry for my english...

Re: [Simpleweb-Support] getParameterValues method on simple.http.Request

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

Hi Dennis,

The Parameters object used to have a getParameters()
method that returned multiple values for a single
name. I removed it some time ago. I had been meaning
to add it back, however I have not got around to it.
Take a look at release 2.6 and you'll see the code for
it in ParameterParser.insert. You can just plug this
in, ill try to add this feature back.

That will return a Parameters object with all of the CGI variables, but I 
don't think it helps in this case.  I need to handle CGI variables with 
multiple values, not just multiple CGI variables.

Consider what happens when you are receiving data from a form with check boxes 
on it.  You will have a single CGI variable with multiple values (one for 
each box checked).  The servlet spec has the method String[] 
getParameterValues() to deal with such cases, but I don't see this for 
Simple.

[Simpleweb-Support] getParameterValues method on simple.http.Request

[Dennis W. <de...@gu...>]

Hi,

I need to handle URLs with multiple values for the same CGI variable such as:

  http://simple.server.com?a=1&a=2&a=3

According to the Simple documentation the Parameters interface "follows the 
parameter methods found in the Java Servlet API Specification."  This means I 
should be able to get multiple values out using the getParameterValues like 
so:

   String[] a = req.getParameterValues("a");

But I don't see this method in the Simple javadoc and it breaks when I try and 
complie my program with this method.

How can I get multiple values for a single named variable?  

TIA,


Dennis

Re: [Simpleweb-Support] Checking SSL for a connection

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

Hi Luke,

Just create a PipelineFactory and check the socket
type. For example,

public class MyPipelineFactory implements
PipelineFactory {

    public Pipeline getInstance(Socket sock) {
       Pipeline pipe = new Pipeline(sock);

       if(sock instanceof SSLSocket) {
          pipe.put("SSLSession",
((SSLSocket)sock).getSession());
       }
       return pipe;
    }
}

And then from the ProtocolHandler.handle you will be
able to do the following.

SSLSession session =
Request.getAttribute("SSLSession");

if(session == null) {
    // not an ssl connection.
}

Of course, you can implement a more suitable scheme.
The point here is that the Pipeline attributes are
available throught the Request object. Via both
Request.getAttribute and Request.getAttributes.

Have a look at BufferedPipelineFactory for an example,
and also simple.http.connect.ConnectionFactory to see
how a pipeline factory can be added into the
conncection procedure.

The bugfix did the trick, thx! The file descriptors weren't the problem 
here since I was testing with *only one* client (one thread). After the 
fix I succesfully completed the same simple test also with 100 continuos 
clients.

Re: [Simpleweb-Support] Simple stops serving - info

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

Hi Hekki,

This bug seems to relate to Java 1.4 on Linux, so if
you use 1.5 it should not be the case. I think if you
repair, the BufferedContent object, you will see an
instant improvement on serving static content. Also,
it is certainly the case that ServerSocket.accept will
fail when the fd soft limit is reached on Linux, as it
cannot create a new fd for the socket....Alternatively
you can wait until later on tonight or tomorrow to
download 2.8.2, which will contain the BufferedContent
cache fix.

[Simpleweb-Support] Simple stops serving - info

[Heikki U. <hu...@al...>]

Relating to my previous post, could this be the reason?

http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=6215050

I can probably test with mustang on tomorrow, or later this week.

Re: [Simpleweb-Support] Simple stops serving

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

Hi Heikki,

What is your soft limit on file descriptors. Just to
remind you, ServerSocket.accept will fail when the
soft limit is reached. This may give JMeter the
impression of deadlock, when in fact it is Linux
limiting performance here. Try the following


ulimit -aS


This will show your fd soft limit, which I expect is
1024. My guess is that if you expect to serve more
than 3000 requests per/sec you will need to increase
you fd soft limit. 

Also there is a caching bug in Simple 2.8.1. This
causes files to be open of each request. So for your
test of 1000 files, 2000 files will be required. How?
well 1000 sockets and 1000 fds for index.html. To fix
the caching bug modify
simple.http.serve.BufferedConent and replace the
following

bug:

   public void write(OutputStream out) throws
IOException {
      if(count > 0) {
         out.write(cache);              
      }           
      int size = getLength();
      
      if(size > 0) {
         write(out,size);
      }
   }

fix:

   public void write(OutputStream out) throws
IOException{
      if(cache == null) {
         int size = getLength();
      
         if(size > 0) {
            write(out,size);
         }
      } else {
         out.write(cache);              
      }
   }

Hope this helps!
Niall

[Simpleweb-Support] Simple stops serving

[Heikki U. <hu...@al...>]

Simple version 2.8.1
Linux 2.6.8-2-k7
Java 1.5.0_06

I'm using Jakarta JMeter to benchmark simple performance. I've tried to 
follow the examples given in simple-demo 1.2.5 (including the usage of 
LinuxConfigurator).

Just by creating a test which loads very basic index.html page 1000 
times (one client) the simple halts after ~30...200 requests.

This phenomenom doesn't occur on WinXP (with same java version).

This phenomenom also doesn't occur on Linux if I set a 1 millisecond 
delay between each request on JMeter.

Any ideas?

Re: [Simpleweb-Support] HTTP Compression

[Carfield Y. <car...@ca...>]

I see, however, once I put the change and compile... I get a very
strangle problem:

clean:

The class is simple and I have totally no idea about this...

BTW, I just double check with my old servlet version of
implementation, there is similar problem, but I just ignore all that
time. However, when I writing application at work, I never experience
this...

Re: [Simpleweb-Support] HTTP Compression

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

Hi Carfield,

It seems as if the client has asynchronously closed
the connection, either due to a browser refresh or
perhaps some other I/O event. To investigate this
further edit the MonitoredOutputStream.java source for
Simple.

Modify the destroy() method to become
destroy(IOException e) and pass all exceptions to the
destroy method. The you can throw these exceptions,
which contain the specific error....this is something
I should have done from the out set. For example:


   protected void destroy(IOException cause) throws
IOException {
      if(open) {
         open = false;
      }
      throw cause;
   }

This will provide the exact stack trace.

Niall

[Simpleweb-Support] HTTP Compression

[Carfield Y. <car...@ca...>]

Try to implement HTTP compression, it work fine at all browser I've
accessable: safari, firefox, opera, internet explorer. However, there
are still socket exception and I don't know why:


java.io.IOException: Stream closed
       at simple.http.MonitoredOutputStream.ensureOpen(Unknown Source)
       at simple.http.MonitoredOutputStream.write(Unknown Source)
       at simple.http.ResponseStream.write(Unknown Source)
       at java.util.zip.GZIPOutputStream.finish(GZIPOutputStream.java:95)
       at java.util.zip.DeflaterOutputStream.close(DeflaterOutputStream.jav=
a:141)
       at hk.com.carfield.web.simple.Controller.rawDisplay(Controller.java:=

       at simple.util.process.Daemon.execute(Unknown Source)
       at simple.util.process.Daemon.run(Unknown Source)

And method rawDisplay is just a method to show the file content directly:


=09private void rawDisplay(Response res, File location) throws IOException,
=09=09=09FileNotFoundException {
=09=09res.set("Content-Encoding", "gzip");

=09=09=09final OutputStream os =3D res.getOutputStream();
=09=09=09OutputStream gos =3D null;
=09=09=09try {
=09=09=09=09gos =3D new GZIPOutputStream(os);
=09=09=09=09final String mime =3D context.getMimeType(location.getName());
=09=09=09=09res.set("Content-Type", mime);
=09=09=09=09IOUtils.copy(is, gos);
=09=09=09} finally {
=09=09=09=09is.close();
=09=09=09=09if(gos !=3D null)
=09=09=09=09=09gos.close();
=09=09=09=09else
=09=09=09=09=09os.close();
=09=09=09}
=09=09}
=09}


The other exception is:

You can always refer to the original Jakarta documentation as well:
