Hi Mika,
I recently read thru your tutorial
(http://raibledesigns.com/wiki/AppFuseXFire.html) on Xfire for Appfuse
and I'd like to say, nice job! Although I'm not direclty using appfuse
in my current project I have in the past and have found to be
fantastic way to jump start my development activites.
But I digress, onto the real point of my message -- I've got
Xfire/Junit testing woes....
In a nutshell I'm tripping up over some Xfire gotchas and being very
new to this technology don't quite yet have enough experience to
bootstap myself up. Essentially, I've crafted this web service
called IEchoWebService (see ~~~ IEchoWebService ~~ below) along with a
JUnit test called EchoWebServiceTest (See ~~~~ EchoWebServiceTest ~~~~
below) that current contains two methods: 1) testGetWsdl(), and 2)
testEcho().
The testGetWsdl() I modelled directly after your example and it passes
without a hitch. In fact, I'm also have this test print out the WSDL
(See ~~~~WSDL ~~~~ below) for my web service and that looks fine too.
However, the second test, testEcho() seems to act like it can't
establish a connection with the service itself (Btw, I'm running this
test in the Eclipse Debugger). In fact, when I make either of the
"IEcho echoIn = service.createEcho();" or "IEcho echoOut =
service.echo(echoIn);" (See ~~~ Unit Test ~~~ below) calls I first
notice a very long delay followed typically by the message "Invalid
Stack Frame" printed in the "Variables" window but *NO* exceptions are
generated. After a period of time these calls return but the
corresponding IEcho objects I expect to get back end up being 'null'.
Looking at the logs (See ~~~~ Logs ~~~~) everything looks quite
reasonable there as well.
Needless to say, I've hunted and pecked around the Net looking for
information on this problem. I've examined quite closely your Appfuse
EchoWebServceTest & UserWebServiceTests, which btw work just fine, and
I'm stumpped. If you would be so kind to take a peek and shoot my
your thoughts I would truly appreciate the help.
Thanks much in advance,
