Re: DII code not working anymore/dynamic stub failing

[Peter G. Lane]

Great googly moogly it works!

operation 'add' successfull:
returnValue: 5
operation 'subtract' successfull:
returnValue: 5
operation 'getValue' successfull:
returnValue: 5
operation 'add' returned: 28
operation 'subtract' returned: -14
operation 'getValue' returned: -14
Thanks Ant!

Sorted (I hope).

The problem is that the testcase in WSIF CVS we've all been using has the
WSDL you originally posted which included only the SOAP binding and
CounterPortType. Where as you've been using WSDL with the
GridServicePortType and all the grid specific stuff. The new test code in
the zip you've just sent in didn't include WSDL so when I tried it I used
that old cut down WSDL which worked fine. I've just hunted around in the
Globus install and in globus\schema\samples\counter found the complete WSDL
and recreated the class cast exception. You'd think the grid specific stuff
in the WSDL wouldn't be relevant as this test isn't using those bindings or
portTypes, but when WSIF is doing the unwrapping of parts it has to parse
all the schema types defined in the WSDL to find the types for the
unwrapped parts, and these extra schema definitions were breaking WSIF.
I've committed a fix, should make it into todays gump build happening in a
few hours, but thats been failing recently due to a xerces build problem,
so you may need to pull it out of CVS yourself to test this - just one
class changed - org.apache.wsif.providers.ProviderUtils.

What *exactly* did you do?  I upgraded WSIF to 2003-03-19, swapped in that
setFeature line, but I
still get the ClassCastException.  Did you happen to install GT3, or are
you using an auto-fab
service from the WSDL?  I even tried this out on another computer to see if
my environment was
somehow messed up.
This has to be a WSDL issue since that's the only thing I see could
possibly be different aside from
supporting jar differences (which doesn't seem very likely considering the
error).  Is there a way
to get WSIF to spit out the WSDL it is consuming?  I would very much like
to compare what I am
getting and what others are getting.

Hi Peter, thanks for zip I've just tried it and with some minor changes
have got it working fine!
I'm not sure if its been clear that you do need to be using a recent WSIF
build for this to work? Can you check you are using a recent WSIF build?
There is a problem with this and WSIF 2.0, so you do need to use a WSIF
jar

from the nightly builds.

The testcase in the zip is still using the old
factory.automaticallyMapTypes(true) method which has now changed to
factory.setFeature( WSIFConstants.WSIF_FEATURE_AUTO_MAP_TYPES, new
Boolean(true)), so you need to change that to work with a recent nightly
build. (Hopefully we'll change this to be the default before the next
WSIF

release so you wont need it at all)

Thanks,

PS, we appreciate anyone who tries to use WSIF so you shouldn't worry
about

asking for help, its our failings that this is taking so long to resolve.

Hi Nirmal,

Yes, this version of the example that Ant wrote is the exact code I am
now

testing with, and it does
indeed cause the errors.
I've attached the directory tree that I've been working out of which
contains, among other things,
this test code and a readme.txt which explains how to test with it based
on

the Globus Tookit(r) 3.0
(lovingly refered to as just OGSA in most places).  My goal was to make
it

as easy as possible for
someone else to reproduce this stuff with our framework.  I know I'm
going

crazy, so I certainly
don't wish it upon anyone else.  Please let me know if there's anything I
can do in the meantime.
Anyway, thanks for all the help.  I'm sure you all hate my guts by now.

Peter

Hi Peter,

I tried out Ant's test below and so has Owen, we have all managed to get
it to work without problems. Does it accurately capture what you are
trying to do?
I will start looking at some of the Globus samples and try writing tests
for them but in the meantime can you see if you see the problem with
this test?
Thanks,
Nirmal.

I'm not really getting anywhere with this and don't have time to look at
the globus samplse right now, so as there seemed to be lots a people here
interested in this, maybe someone else has some time to look at the
samples


Peter points to at http://www.globus.org/ogsa/releases/alpha/

I've committed the testcase I use for this into defects.ogsa package.
Works


fine for me, so I'm not sure why it doesn't for Peter. Does it work for
you?

Hmmm, I don't know what to say.  I substituted in your wsif.jar and
massaged the test case so it
would work with my package hierarchy and the new namespaces we just
changed


to, but I get the exact
same error with the stub code.  I am attaching my altered java file just
in


case I did something stupid.

P.S.  If you're feeling curious and ambitious, you can download our
software which contains all of
our schemas and samples to test against:

Hi Peter,

I hope you're not getting to put off of WSIF.  I'm a bit confused

about


which WSIF code you're running, and what patches I've already

committed


for

you. Here's the latest WSIF jar which includes the fixes from the
previous

patches so I know exactly what you are running with.

I've a test case based on the counter WSDL you initially sent and this
really does work ok for me. It needs to set  the style in the context

for


stubs, and for the getValue call with the DII. Hopefully I can get the
stub

based calls to mostly work this out itself based on the types of the
input

parts next week. With the getValue call where there are no input parts
its

hard to tell what you really want so the context will still be

required,


although a better default would be to use unwrapped, which I'll also
change

next week.

This wsif gives a SOAP request which looks more correct:

<soapenv:Body>
 <subtract xmlns
="http://samples.ogsa.globus.org/counter/counter_port_type";>
  <ns1:value xsi:type="xsd:int" xmlns:ns1
="http://samples.ogsa.globus.org/counter";>9</ns1:value>
 </subtract>
</soapenv:Body>
Anyway, hopefully this will sort out all the trouble this has been
causing

you, please let me know how you get on.

This doesn't seem to help either.  I removed all code to manually

unwrap


things, and added code to
check for wrapped style and to set the context part as you instructed
right

before I get the stub.
I even tried setting this before I do an

executeRequestResponseOperation


()

(which I can get to
work), but that stops functioning too without the manual unwrapping.

Anthony Elder wrote:


Woh, deja vue.

Hi Peter,

Its not really clear why you are doing anything to do with unwrapping
parts? WSIF should be doing all that for you under the covers for both
the


stub and DII interface. Just make the WSIF call and WSIF should work

out


if


you're parameters match wrapped or unwrapped parts. There are a couple

of


circumstances where WSIF gets this wrong, I'm in the middle of trying

to


make this more robust. but for the moment sometimes you have to tell

WSIF


which to use. I think this is what's going wrong with you stub calls.

You tell WSIF you want to use wrapped or unwrapped parts by setting a
part


in the context method, for example this code should fix the stub

problem:


 WSIFService service =
    factory.getService(
       "bin/ogsa/counter.wsdl",
       "http://samples.ogsa.globus.org/counter";,
       "CounterService",
       "http://samples.ogsa.globus.org/counter/counter_port_type";,
       "CounterPortType");
 WSIFMessage ctx = service.getContext();
 ctx.setObjectPart(
    WSIFConstants.CONTEXT_OPERATION_STYLE,
    WSIFConstants.CONTEXT_OPERATION_STYLE_WRAPPED);
 service.setContext(ctx);
 CounterPortType stub =
    (CounterPortType) service.getStub(portName,

CounterPortType.class);

I'm having trouble with one of the latest nightly build jars.  I had

DII


working last month, but recent changes seemed to have prevented

further


success.  One thing I noticed is that unWrapPart() is deprecated.  I'm

a


little nervous now about what I should be doing in lieu of that since

I


use getWrappedDocLiteralPart() which is not deprecated and implies I'd
have to then unwrap it.  It looks like this is causing problems with

the


DII method:
