SOAP::Lite and XML

[cerror]

Hello Monks,

I know I'm kind of rehashing an old node, but I've made some progress and would like some advice on how to proceed from here. I think the problem I've been having may be in the way SOAP::Lite serializes the array, though I may be mistaken. Here's the relevant offending code from my XRC module as it is now:

sub changePkg {
        my ($username, $pkg) = @_;
                
        my $client = connectXrc();

        my $result = $client->setUserOffers(
                XRC_CLIENTID,
                $username,
                $pkg);
}

The wsdl file defines setUserOffers like so:

<wsdl:message name="setUserOffersRequest">
  <wsdl:part name="clientID" type="xs:int"/>
  <wsdl:part name="username" type="xs:string"/>
  <wsdl:part name="offerIDs" type="types:ArrayOfInt"/>
</wsdl:message>

And ArrayOfInt like this:

<xs:complexType name="ArrayOfInt">
  <xs:annotation><![CDATA[
    A SOAP encoded array of the xs:int type.
  ]]></xs:annotation>
  <xs:complexContent>
    <xs:restriction base="soapenc:Array">
      <xs:attribute ref="soapenc:arrayType" wsdl:arrayType="xs:int[]"/
+>
    </xs:restriction>
  </xs:complexContent>
</xs:complexType>

My test, which fails, is very simple. The relevant parts look like this:

my @pkg = 5544;

print "username: ";
my $username = <STDIN>;
chomp($username);

XRC::changePkg($username, @pkg);

Everything works except offerIDs (@pkg). My XML that's passed to the server defines it like this:

<offerIDs xsi:type="types:ArrayOfInt">5544</offerIDs>

However, it always fails with this fault:

<faultstring>org.xml.sax.SAXException: Found character data inside an 
+array element while deserializing</faultstring>

I know I'm not actually passing a string, so I'm not really certain what's going on here. Google gave me some ideas, which I tested, but nothing ultimately came of it. Does anyone else have a suggestion?

Thanks!

Similar to your previous node, try passing a reference to the @pkg array:

XRC::changePkg( $username, \@pkg );

I still don't have access to the required wsdl file, so it's a bit of a guess, but here's what SOAP::Lite generates for the array without the wsdl:

<soapenc:Array soapenc:arrayType="xsd:int[1]" xsi:type="soapenc:Array"
+>
      <item xsi:type="xsd:int">5544</item>
</soapenc:Array>

I think you'll find it'll turn out alright when the wsdl is in place.

When I do that, I end up passing:

<offerIDs soapenc:arrayType="xsd:int[1]" xsi:type="types:ArrayOfInt"><
+item xsi:type="xsd:int">5544</item></offerIDs>

and the fault is:

<faultstring>org.xml.sax.SAXException: No deserializer for int</faults
+tring>

I tried almost every permutation I could think of. I've posted the entire wsdl file here if you think it'll help (minus the actual username/password).

Thanks for all your help so far. :-)

You seem to be using Java Axis. Are you able to use the WSDL from a Java client to call the server, instead of SOAP::Lite?

I'm not a WSDL expert or anything, but yours doesn't look right to me. I'd think you'd need another <element> definition in there for each thing inside of the <offerIDs> element, like

<xs:complexType name="ArrayOfInt">
  <xs:complexContent>
    <xs:restriction base="soapenc:Array">
      <xs:sequence>  <!-- NB: adding 'item' elements here -->
        <xs:element name="item" type="xsd:int"/>
      </xs:sequence>
      <xs:attribute ref="soapenc:arrayType" wsdl:arrayType="xs:int[]"/
+>
    </xs:restriction>
  </xs:complexContent>
</xs:complexType

I could easily be wrong about that, though.

If your WSDL is publicly visible on the web, you might be able to use www.xmethods.net to test correct usages. It worked for me once upon a time. I don't know their terms of service, but they have many examples they offer to test for you.

Sometimes SOAP::Lite is more cumbersome than template toolkit or a simple here doc. The key is to find out what a good packet looks like to the server. Then you can template it.
