How to capture a SOAP exception from a webservice?

Nate Imaqaguy

8/2/2006 9:43:00 PM

Iâ??m trying to catch a soap exception from a web service, but Iâ??m a n00b
and am having a hard time figuring it out.

Iâ??m using ruby 1.8.4 (win32)--if it matters.

Iâ??ve got the start of my program created and can receive successful soap
objects back from the webservice. So thatâ??s all working good.

Next, I want to capture SOAP exception errors. For example, Iâ??ll get a
message saying something does not exist or is not found. This is the
same message that is in the return XML â??faultstringâ? tag.

Do I have to find a way to parse the returned XML, or is there an easy
way to grab the soap exception I'm looking for?

Thanks for the help. BTW, I tried to use the forum search (I always try
that first), but it's down for maintenance or something like that.

Thanks all,

-nate

begin
@query = @soap.apiFunction(
{'Key'=>'Value','Key2'=>Value2'}
)
#rescue ::SOAP::FaultError => e
rescue ::XSD::ValueSpaceError => e
assert_equal("{http://www.f...}FooBarEnum: cannot accept
'foo'",e.to_s)
end

Hope that helps...

Hmmmâ?¦

**If** I understand what you were trying to tell me, I **think** I
adapted your example to my code and came up with this. BTW, â??paramâ? is
an int Iâ??m passing to the method.

----------------------------
if results = soap.FindPatientById( param )
then puts results.first_name
puts results.last_name
else
begin
rescue ::SOAP::FaultError => e
# rescue ::XSD::ValueSpaceError => e
puts e.to_s
end
end
-----------------------------

I had something pretty similar to this already. â?¦but itâ??s not
working.

The way Iâ??m doing it, I donâ??t think I needed the â??assert equalâ?
statementâ??right? The most confusing parts to me are the â??rescueâ? lines.
Specifically, which one to use (I went with SOAP, but tried both) and
how you knew to put â??FaultErrorâ? there.

Like I said, Iâ??m a total n00b to ruby. I havenâ??t even tried programming
anything since my last C class about 6 years ago, so please be patient
if Iâ??m missing something obvious.

= )

Thanks again,

-nate

Hello.

= )

I know I'm close on this one--I can feel it. Can anyone help? I'd
appreciate it a lot.

Thanks,

From what I understand, I believe your method call has to be inside
the "begin...rescue" block, or "rescue" won't be able to see the error
when it happens.

In other words, something like this:

begin
if ( results = soap.FindPatientById( param ) )
puts results.last_name
end
rescue ::SOAP::FaultError => e
puts e.to_s
end

I've fired a GPMG from the hip, but that was a paltry .3inch.

An M79 grenade launcher has some kick to it. Never tried one of them
newfangled over/under hybrids with the M-16.
