James Foster has updated his "how to":

Some time ago I described the steps I used to add Perl as a simple runtime and framework to Cloud Foundry. Since then many changes have taken place in Cloud Foundry and those steps no longer work. I now have something that works as of 30 August 2012. To see the changes go to my github repository and view the changes to  vcap, vcap-staging, stager, and cloud_controller. Note that the recent refactoring of Cloud Foundry means that instead of isolating changes to one repository, we now make changes to four repositories.

Yet another reason I wish I was at ESUG this year - the people in that part of the Smalltalk community are great. They just sent me this (click through for the full size version):

Today we'll take a look at DDE support in VA Smalltalk. While DDE is an old way of doing inter-process communication, it still works well, and it's easy to use. To start, load the DDE-Examples package from the features tool, and then find the DDE-Examples Application:

Have a look at the DDETimeServer and the DDETimeClient. We'll be using those for the purpose of this example. Just create an instance of the server in a workspace:

Then create the client - you should see the time printing to the Transcript. All this example does is set up a topic for the client to find, and, when found, print to the Transcript:

Craig Latta:

Huge thanks to yesplan.be for hosting Camp Smalltalk at ESUG 2012 in Gent, Belgium! I walked in and connected my computer to a humongous display and wireless keyboard/mouse, and connected myself to a humongous pile of speculoos, koffie, and Belgian chocolate. :)  All while a charming street festival went on outside. This is the perfect recipe for classic code!

Today we'll go back to the Web Services example we had been building in VA Smalltalk. To get started, recall the simple example we'll be using - a "counter" class:

The first thing we'll need is a server to listen on a port. Start that this way:

server := SstHttpServerExample
        runAt: 'http://:7777'

        in: ('C:\Program Files\Instantiations\VA Smalltalk\8.5\xml').

The file path should be to wherever you have VA looking for the XML files, as specified in your ini file.

If you do that correctly, you should see a console window like the following appear:

That window will log what's happening, so if anything goes wrong, you can examine the results. Next, you'll need to deploy the container for your WS* application:

SstWSContainer clearAll.

"create server container" 

[ | aContainer  | 
aContainer := SstWSContainer
        createContainerNamed:  'ServerContainer'
         using: (SstWSContainerConfiguration defaultConfiguration).
        aContainer startUp.
        aContainer deploy:   'http://localhost:7777/CounterServer.xml'] fork.

You should see some reporting in the server log after doing this:

Now, we are ready to actually set up and invoke the code through a client. Here's the code for that:

"create client container" 

[ "| cContainer counterService |"
    cContainer := SstWSContainer
        containerNamed:  'ClientContainer'
        ifNone: [SstWSContainer createContainerNamed: 'ClientContainer'].
        cContainer deploy:   'http://localhost:7777/CounterClient.xml'.


   "two ways to retrieve the service from the client" 

   "counterService := (SstWSContainer 
		containerNamed: 'ClientContainer') allServices first. "
   counterService := (SstWSContainer containerNamed: 'ClientContainer') 
	serviceNamed: 'Counter' inNamespace: 'http://www.Counter.com/Counter-impl'.

   "result should be the string returned from the Counter class methods" 

   (counterService addValue: '5') inspect.
   (counterService subtractValue: '10' ) inspect  ] fork.

Notice the lines at the end where we invoke the service. If everything went well, you'll see two signs that it all worked - lines in the Transcript from the code, and more entries in the log:

Finally, if you want to experiment with the example, you may need the following "clean up" code - to clear out your listeners and start fresh:

(SstWSContainer containerNamed: 'ServerContainer') shutDown.

(SstWSContainer containerNamed: 'ClientContainer') shutDown

Sounds like hosting on Dart is a better idea than on Javascript. However, does any browser other than Chrome actually support Dart directly?
