problems using getAnyObject() -- please help
Hi all,
I have been struggling with this for days. I've finally reached the
point where I can't get any further and need to reach out for help.
I need to be able to work directly with the XML contents of the SOAP
request rather than going through one of the objects created in the
server side stubs. The only way I've discovered to be able to do this
is by using IWrapperSoapDeSerializer::getAnyObject(). I thought this
was the appropriate method because of the comments in the header: Will
deserialize the next available SOAP element and all child elements.
I will walk through some examples of what I've tried in an attempt to
properly explain the issues I am running into. Note that these are just
code snippets, I am leaving some of the obvious code out, and you can
pretty much assume that I've set things up properly. Here is what I did
with my first attempt at printing out the XML:
AnyType *pV0 = pIHSDZ-getAnyObject();
for (int i = 0; i pV0-_size; i++)
{
cout pV0-_array[i];
}
This only printed out part of the XML. As such, I realized that I
needed to make multiple calls to getAnyObject() in order to get the next
elements, so I tried this:
AnyType *pV0 = pIHSDZ-getAnyObject();
while (pV0 != NULL)
{
for (int i = 0; i pV0-_size; i++)
{
cout pV0-_array[i];
}
pV0 = pIHSDZ-getAnyObject();
}
This resulted in a segmentation fault, which after reading multiple
posts online, I discovered that it was because getAnyObject() will never
return NULL, so we end up making calls to it even after no further
objects remain, resulting in the segmentation fault. This is where my
confusion comes in. If I ended up getting all the XML and then made a
call to getAnyObect() and it then seg faulted, I would completely
understand. However, it seg faults after I only get part of the XML
(leading me to believe that further calls to getAnyObect() actually
SHOULD return something).
Let me illustrate this with an example. Say the XML contents of the
SOAP message is the following:
?xml version=1.0 encoding=UTF-8?
mantas:MantasAlertData
xmlns:mantas=http://namespaces.mantas.com/MAD;
xmlns:action=http://namespaces.mantas.com/MAD/Action;
xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance;

Attribute name=EXTRL_NTITY_TYPE_CD
type=stringNM/Attribute
/MatchedData
/MatchedRecord
/MatchedDataRecords
/MatchInformation
/Matches
/AlertData
/mantas:MantasAlertData
If you run my above code, this is what will get output to the consoled
before the segmentation fault:
?xml version=1.0 encoding=UTF-8?
mantas:MantasAlertData
xmlns:mantas=http://namespaces.mantas.com/MAD;
xmlns:action=http://namespaces.mantas.com/MAD/Action;

RelationshipMatched/Relationship
MatchedData
Note that there a few things wrong with this. First of all, why doesn't
the rest get printed out? If there is more data, why does it seg fault?
I even put in a counter to check how many times I go through the loop
before it seg faults, and limited the loop to that number...that solves
the seg fault issue, but I still don't get all the data. Secondly, the
data is somewhat corrupted: I don't know where the extra slashes have
come from (e.g. /RecordType/ instead of /RecordType). The same
happens with the reverse situation as well. That is, if I try to feed
some XML through an AnyType object back into the response, it also gets
corrupted. For example, the following code:
pIWSSZ-createSoapMethod(PrioritizeAlertResponse,http://namespaces.te
ch.com);
try
{
AnyType *pAny = new AnyType();
pAny-_size = 1;
pAny-_array = new char*[1];
pAny-_array[0] = AlertData/AlertData;
return pIWSSZ-addOutputAnyObject(pAny);
}
Produces the following response:
?xml version=1.0 encoding=UTF-8?SOAP-ENV:Envelope
xmlns:SOAP-ENV=http://schemas.xmlsoap.org/soap/envelope/;
xmlns:xsd=http://www.w3.org/2001/XMLSchema;

AlertData//ns1:PrioritizeAlertResponse

Vineet,
First I want to make sure you are using the latest code from SVN and not
1.6b.
I have a lot on my plate but I can take a look sometime next week.
Assuming you are, and to expedite the debugging I will need to do, please
attach a complete simple client examplesince you already showed the a
SOAP response I do not need that.

RE: problems using getAnyObject() -- please help
Nadir,
Thanks for your message. I actually am using 1.6b and not the latest
code from SVN. Unfortunately, I can't seem to compile a version myself
that works, so I've been using the pre-compiled binary for Linux (when I
do a build myself, it builds fine, but seg faults when I try to run
anything, including just the simple_axis_server).
My application is quite large, so I'm not sure I'll be able to build a
small program to reproduce the problem, but I will certainly try.
Perhaps I can modify the Calculator example to break (it currently works
fine for me). What exactly do you need, just the client code, or all
the code involved?
Thanks again,
Vineet
