We're using Axis version 1.5 and it seems to work fine:
Ah, my bad -- we're still using 1.4
While I understand what you're saying, I also think this can be a slippery slope. Admittedly the change you're asking for is quite minor, but my stubbornness kicks in when I think of it like this: how do we attain interoperability without making everybody implement N different variations of the specs we use? If we let people be non-conformant and even bend over backwards when they are non-conformant, we're putting the burden on everybody to accomodate all non-conformant variations that may pop up. That's no way to operate in my mind. You should define the dimensions of your widget and then mass produce it. Slight variations may occur within tolerances, but element refs to me isn't within tolerances. They're pretty fundamental IMHO.
Well, my experience has been that WSDL, like C++ of old, has gotten too complicated and as such, NO ONE correctly implements it 100%. This happens to be a problem that mine has -- next it could be yours.
Anyway, I'm off my soap (no pun intended) box. Since the change is rather benign, I'm not going to get in a tiff if others agree this is worth doing. But if you want to switch to a working Axis version, you're welcome to use the Globus Toolkit! ;-)
That's OK -- like I said, I don't believe yours is 100% correct either, so I'll stick with the one I know and can fix. And don't worry about the WSDL, I just thought we might want to find a common subset of WSDL that everyone understands, but seeing as how this isn't the trivial issue I thought it was, I'll just post an alternate but equivalent form of the WSDL that people using Axis 1.4 can use. -Mark

Doesn't JSDL cause problems for your tooling as well? Element refs are a very common XMLSchema feature. JSDL uses quite a number of them. What about the HPCProfileApplication schema? I'm wondering whether changing the BES schema would actually help that much. I'm also worried that changing the demo copy of the schema for broken tooling would cause those changes to get propagated to the normative BES schema. My personal preference is that you change it locally rather than forcing us to endorse the change.

OK -- I thought as much. So, my tooling is bad -- can we change the WSDL anyway since the change shouldn't only be duplicate information for other peoples tooling (the goal is to be maximally interoperable right?). Ofcourse, I have to change the WSDL one way or the other, would just like to use the same WSDL everyone else is using.

From the XMLSchema spec (http://www.w3.org/TR/xmlschema11-1/#cElement_Declarations):
"The (top-level) element declaration .resolved. to by the .actual value. of the ref [attribute]."
This means essentially that the global element declaration will be substituted for the element reference. In other words, the name must be "ActivityIdentifier" in the bes-factory namespace. If your tooling isn't doing this then it's non-compliant.

In trying to interop with Glenn's endpoint, I have found another potential problem with the BES-Factory's WSDL. However,
is at a level of WSDL that is slightly beyond my experience. In particular, the problem is with two message types; the GetActivityDocuments message type, and the TerminateActivitiesType message. Both problems are identical. In brief, here are three elements from the WSDL (the first of which is an example of a type declaration which works for me, and the latter two being
<xsd:complexType name="GetActivityStatusesType"> <xsd:sequence> <xsd:element name="ActivityIdentifier" type="wsa:EndpointReferenceType" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType>
<xsd:complexType name="GetActivityDocumentsType"> <xsd:sequence> <xsd:element ref="bes-factory:ActivityIdentifier" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType>
<xsd:complexType name="TerminateActivitiesType"> <xsd:sequence> <xsd:element ref="bes-factory:ActivityIdentifier" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType>
The first one works for me, and the last two do not. The

the second and third ones is that my tooling doesn't know what name to give the element for the EPRs inside of the message elements.. In otherwords, it generates messages which look like the following:
<GetActivityDocuments xmlns="http://schemas.ggf.org/bes/2006/08/bes-factory"> <item xmlns="" xmlns:ns3="http://www.w3.org/2005/08/addressing" xsi:type="ns3:EndpointReferenceType">
<ns3:Address>https://wincluster1.cs.virginia.edu/HPCP/HPCPServ ice.asmx</ns3:
Address> <ns3:ReferenceParameters> <jobID xmlns="http://schemas.ggf.org/hpcp/2006/07/hpcp-app">113</jobID> </ns3:ReferenceParameters> </item> </GetActivityDocuments>
<TerminateActivities xmlns="http://schemas.ggf.org/bes/2006/08/bes-factory"> <item xmlns="" xmlns:ns3="http://www.w3.org/2005/08/addressing" xsi:type="ns3:EndpointReferenceType">
<ns3:Address>https://wincluster1.cs.virginia.edu/HPCP/HPCPServ ice.asmx</ns3:
Address> <ns3:ReferenceParameters> <jobID xmlns="http://schemas.ggf.org/hpcp/2006/07/hpcp-app">113</jobID> </ns3:ReferenceParameters> </item> </TerminateActivities>
Notice the child element called "item" in each message.
The simple (and obvious to me) fix was to change the GetActivityDocuemntsType and TerminateActivitiesType type definitions to specify the name of the inner element, i.e. to change them to:
<xsd:complexType name="GetActivityDocumentsType"> <xsd:sequence> <xsd:element name="ActivityIdentifier" ref="bes-factory:ActivityIdentifier" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType>
<xsd:complexType name="TerminateActivitiesType"> <xsd:sequence> <xsd:element name="ActivityIdentifier" ref="bes-factory:ActivityIdentifier" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> </xsd:complexType>
I know that these are legitimate fixs, the questions are, A) are these in fact real errors that my tooling is finding and thus the WSDL is in error, and B) can we make these changes permanent in the BES-Factory WSDL to fix these problem?
