adb and loosely typed parameters
Hi,
I've created a service based on a WSDL (generated sources with "WSDL2C
-ss -sd -d adb -u -f -uri") and it seems to work fine for parameters and
return values with fixed type.
Some of my functions can take any parameters, e.g. from my WSDL:
...
<wsdl:types>
...
<s:element name="SetSymbol">
<s:complexType>
<s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="pName"
type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="pData" />
</s:sequence>
</s:complexType>
</s:element>
<s:element name="SetSymbolResponse">
<s:complexType />
</s:element>
...
</wsdl:types>
...
<wsdl:message name="SetSymbolSoapIn">
<wsdl:part name="parameters" element="tns:SetSymbol" />
</wsdl:message>
<wsdl:message name="SetSymbolSoapOut">
<wsdl:part name="parameters" element="tns:SetSymbolResponse" />
</wsdl:message>
...
<wsdl:portType name="StatConnectorSoap">
...
<wsdl:operation name="SetSymbol">
<wsdl:input message="tns:SetSymbolSoapIn" />
<wsdl:output message="tns:SetSymbolSoapOut" />
</wsdl:operation>
...
</wsdl:portType>
...
<wsdl:binding name="StatConnectorSoap" type="tns:StatConnectorSoap">
...
<wsdl:operation name="SetSymbol">
<soap:operation
soapAction="http://www.statconn.com/StatConnector/SetSymbol"
style="document" />
<wsdl:input>
<soap:body use="literal" />
</wsdl:input>
<wsdl:output>
<soap:body use="literal" />
</wsdl:output>
</wsdl:operation>
...
</wsdl:binding>
<wsdl:binding name="StatConnectorSoap12" type="tns:StatConnectorSoap">
...
<wsdl:operation name="SetSymbol">
<soap12:operation
soapAction="http://www.statconn.com/StatConnector/SetSymbol"
style="document" />
<wsdl:input>
<soap12:body use="literal" />
</wsdl:input>
<wsdl:output>
<soap12:body use="literal" />
</wsdl:output>
</wsdl:operation>
...
</wsdl:binding>
...
The generated function signature is
adb_SetSymbolResponse_t* axis2_skel_StatConnector_SetSymbol(const
axutil_env_t *env,adb_SetSymbol_t* _setSymbol );
and adb_SetSymbol.h contains the following accessor functions:
axis2_char_t* AXIS2_CALL
adb_SetSymbol_get_pName(
adb_SetSymbol_t* _SetSymbol,
const axutil_env_t *env);
axiom_node_t* AXIS2_CALL
adb_SetSymbol_get_pData(
adb_SetSymbol_t* _SetSymbol,
const axutil_env_t *env);
The SOAP payload from the request message sent from my test application
(done in C#) is:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SetSymbol xmlns="http://www.statconn.com/StatConnector">
<pName>myvar</pName>
<pData xsi:type="ArrayOfAnyType">
<anyType xsi:type="xsd:double">3.14</anyType>
<anyType xsi:type="xsd:int">815</anyType>
<anyType xsi:type="xsd:string">My String</anyType>
</pData>
</SetSymbol>
</soap:Body>
</soap:Envelope>
When now calling adb_SetSymbol_get_pData(), I expected to get access to
all elements of pData. So I wrote a simple recursive tracing functions
showing the data I got:
int iterateNodes(axiom_node_t* pNode,axutil_env_t const* pEnv,int pLevel)
{
axiom_node_t* lNode;
printf("MyFun#%d: node <%s> is of type %d\n",pLevel,
axiom_node_to_string(pNode,pEnv),
axiom_node_get_node_type(pNode,pEnv));
lNode = axiom_node_get_first_child(pNode,pEnv);
if(lNode) {
iterateNodes(lNode,pEnv,pLevel+1);
}
lNode = axiom_node_get_next_sibling(pNode,pEnv);
if(lNode) {
iterateNodes(lNode,pEnv,pLevel);
}
return 0;
}
And this function gets called from axis2_skel_StatConnector_SetSymbol()
like this:
iterateNodes(adb_SetSymbol_get_pData(_setSymbol,env),env,0);
Unexpectedly the stdout shows:
MyFun#0: node <<anyType
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:type="xsd:double">3.14</anyType>> is of type 2
MyFun#1: node <3.14> is of type 8
axiom_node_get_next_sibling for adb_SetSymbol_get_pData(_setSymbol,env)
returns NULL.
I'm quite sure this is a misunderstanding in the way I'm using the
adb-functions, but I just can't find the problem.
Additionally, if sending not an array, but just a simple scalar:
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<SetSymbol xmlns="http://www.statconn.com/StatConnector">
<pName>myvar</pName>
<pData xsi:type="xsd:double">3.1415</pData>
</SetSymbol>
</soap:Body>
</soap:Envelope>
the traces show
MyFun#0: node <3.1415> is of type 8
Is there any way to find out the type informatino (xsd:double in this
case) from adb_SetSymbol_get_pData()?
Best,
Thomas

Hi,
yea look like it is a bug in wsdl2c. I think having the condition check
<xsl:when test="@any or not(@type)"> should solve the issue. Please raise a
jira for this.

Thanks for this tip. It works fine now. Unfortunately I have spent the
better half of a day in parsing the message myself without adb, but at
least I now seem to understand a few things ;-)
The WSDL itself is generated by Visual Studio 2008, so unfortunately
this seems to be a fairly common problem when using some WSDL from a
VS.NET Webservice.
Thanks again,
Thomas

Hi,
Can you try change your wsdl to <s:element minOccurs="0" maxOccurs="1"
name="pData" *type="s:anyType"* /> and regenerate the code and see whether
you getting the correct result?
The template code for axiom_node_t type is
<xsl:when
test="$nativePropertyType='axiom_node_t*'">
text_value = NULL; /* just to avoid
warning */
<xsl:choose>
<xsl:when test="@any">
{
axiom_node_t
*current_property_node = current_node;
current_node =
axiom_node_get_next_sibling(current_node, env);
axiom_node_detach(current_property_node, env);
status = <xsl:value-of
select="$axis2_name"/>_set_<xsl:value-of select="$CName"/>(<xsl:value-of
select="$name"/>, env,
current_property_node);
}
</xsl:when>
<xsl:otherwise>
if(axiom_node_get_first_child(current_node, env))
{
axiom_node_t
*current_property_node = axiom_node_get_first_child(current_node, env);
axiom_node_detach(current_property_node, env);
status = <xsl:value-of
select="$axis2_name"/>_set_<xsl:value-of select="$CName"/>(<xsl:value-of
select="$name"/>, env,
current_property_node);
}
else
{
status = <xsl:value-of
select="$axis2_name"/>_set_<xsl:value-of select="$CName"/>(<xsl:value-of
select="$name"/>, env,
NULL);
}
</xsl:otherwise>
</xsl:choose>
</xsl:when>
Looking at the results of your code, I think what has generated here is the
code inside the <xsl:otherwise> tag (mean <xsl:when test="@any"> is false).
So explictly setting the anyType should correct your problem.
Thanks
