Web Services Tutorial, JokeOfTheDay no longer works

Executing from the WebServices book:

| wsdlClient soapRequest soapResponse |
wsdlClient := WsdlClient new loadFrom:
'http://services.xmltoday.com/vx_engine/wsdl.vep?joke.wsdl' asURI.
soapRequest := SoapRequest new.
soapRequest port: wsdlClient config anyPort.
soapRequest smalltalkEntity:
(Message selector: #JokeOfTheDay ).
soapResponse := soapRequest value .

Gives me a "referent inaccessible" It looks like the webservice no
longer runs there. Is there another example coming in the next version
of the book?

Re: Web Services Tutorial, JokeOfTheDay no longer works

I'm looking around just for something simple to try. What's really
needed is a publicly accessible "Hello, world!" service.

Anyway, even this doesn't work:

WsdlClient new loadFrom:
'http://interpressfact.net/webservices/getjoke.asmx' asURI.

I need a simpler test service. Instead of returning something
inspectable I get, "Unhandled exception: The close tag for br was not
found."

I appreciate that it's a good thing to get well-formed XML in a
response, but what's obnoxious is the intolerance of clients. Perhaps
that's a problem with XML. Humans can read sentences with misspelled
words and web browsers are tolerant of malformed HTML. In this case the
text coming back has a <br> when a <br/> is what was intended -- and if
not intended at least correct.

Perhaps the exactitude of XML well-formedness makes things too brittle?

Re: Web Services Tutorial, JokeOfTheDay no longer works

I was able to get this to work. Perhaps the tutorial could be updated
with it:

| wsdlClient soapRequest soapResponse |
wsdlClient := WsdlClient new loadFrom:
'http://lepago.homeip.net/HelloLangJB4EJB/HelloLangEndpointPort?wsdl'
asURI.
soapRequest := SoapRequest new.
soapRequest port: wsdlClient config anyPort.
soapRequest smalltalkEntity: (Message selector: #sayHello arguments:
#('Hello, world.')).
soapResponse := soapRequest value .

The response was "Hello, world! not in database (yet)" I don't know if
it was the correct response but it wasn't an exception.

I created AR#50680 to improve the WS client error messages.
