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?

CodeCity started out in VisualWorks, but issues around Cincom's licensing have driven the development efforts to Pharo. The toolset is not open source, which means that people are choosing to use Pharo for proprietary, commercially oriented work.

Maybe that last 18 months of college (way, way back when :) ) was good for me:

But today new research being released at the annual meeting of the American Sociological Association reports that college students who binge drink are happier than those who do not.

The VA tools have a lot of options on the toolbars, but what if you want more? For instance, what if you really want to be able to open a browser from the workspace? Under Options on the Launcher, pull right at Toolbars:

Select a tool in the menu, then move options to on or off. Be careful with the mouse wheel; it's easy to change the menu when you intend to scroll through options:

Now, open a new workspace after adding the Class Browser icon - you should see your toolbar item:
