Hi,
EntireX Communicator 7.3.1 on Windows XP
Generate Web Service from Software AG IDL
IDL contains arrays defined at group level as (/1:V)
Resultant xmm and wsdl specify minOccurs = 1 (e.g. <xsd:element minOccurs=‘1’ maxOccurs=‘unbounded’…)
What needs adjusting so that minOccurs = 0?
I can edit the xmm, change the Min Occurences from 1 to 0, and generate the wsdl correctly from there, but what am I missing?
Regards,
Willie
did you try changing the IDL to 0:V?
is this an OUT or IN structure? If IN, the subprogram needs to check that the bounds are greater than 0 before accessing the array.
Hi,
Our web service is a Natural subprogram wrapped by EntireX.
It is the Out structure that is giving a problem in a C# application (not ours) that is using our web service. That application is crashing because it is expecting the minimum 1 occurrence (as specified by the wsdl) of a decimal field. Instead it is getting an empty tag and is reacting badly.
As soon as I edit the xmm and change Min Occurences from 1 to 0, the wsdl shows MinOccurs=‘0’, the resulting xml no longer has the empty tag at all, and the C# application is happy. Only I am not happy because of this intervention, which may be necessary only because of my ignorance of EntireX.
The Natural subprogram does not ‘materialize’ the array if there is no data for it. I can imagine that materializing the array for at least one occurrence will avoid the C# crash by returning a tag containing a zero rather than the empty one, but I would prefer to avoid sending the unnecessary tags.)
Changing the array group definition in the IDL from (/V) or (/1:V) to (/0:V) makes no difference to the xmm Min Occurences. The IDL Grammar manual hints that for x-arrays minOccurs will be 1: unbounded-array-index ::= [1:] V[maximum-upper-bound]
Changing assorted perferences for the XML Mapping Editor in EntireX Workbench doesn’t seem to help either.

Willie
I checked this scenario with EntireX 8.2. The min occurs is set to 0.
It’s probably a good idea to upgrade to a newer version of EntireX, 7.3 is out of support since long time.
:lol:
Of course, why didn’t I think of that? (Because upgrading is often the last resort when you are a mere developer.)
Thank you so much, Ralph.
Off to SAG now to do some shopping…

Hi,
So now I have Software AG Designer 8 installed on my pc, with no plans to install NaturalONE instead of Natural Studio, and Designer 8 generates a wsdl from a Natural IDL file with the desired minOccurs = 0.
But the location in the wsdl is location=“http://localhost:10010/wsstack/services/Test”/
The manual says:
[i]From the context menu of the IDL file, choose Properties.
Change the EntireX settings if necessary.
If necesssary, change the Web service generation settings using the WSDL tab (Service Name and Service URL).
Choose OK to leave the Properties dialog. [/i]
The problem is that I can’t see a field labelled Service URL where I would expect it, and the Web Services Wrapper insists on using location=“http://localhost:10010/wsstack/services/Test”/
The manual goes on:
Before the wizard is started for the first time, you should initialize the preference pages Window > Preferences > Software AG > EntireX and Window > Preferences > Software AG > EntireX > Web Service Wrapper with values appropriate for your environment.
I have changed the URL of XML Runtime (and ticked the box ‘Configure service with XML-INIT’) but to no avail.
Have I installed Designer 8 incorrectly, perhaps with wrong installation parameters? Are there other preferences that need tweaking?
Forgive me if I haven’t read enough of the manual.

Willie
Starting with v8.0 the architecture changed, it now uses the “Web Service Stack” (hence the
reference to “wsstack” in the URI):
Willie,
what is your problem? That’s not clear to me.
Hi Rolf,
I have MyService.idl. I want to generate MyService.wsdl. The service URL (or location=) needs to be http://MyURL.co.za:8180/TestServices/xmlrt
How is this possible using Generate Web Service from Software AG IDL in Designer 8.2 on Windows 7?
Willie
not sure why the specific URL is important (endpoints get updated all the time as the services move from dev to prod), but if you want backward compatibility, see
http://techcommunity.softwareag.com/ecosystem/documentation/webmethods/entirex/exx801/adminWin/setupXmlSoapListener.htm#mig_entirex-forward
Although I don’t see it documented in v8.2, entirex-forward.jar is still provided in \EntireX\webapps. To get “TestServices” instead of “entirex” in the URL, rename the entirex-forward.jar file as TestServices.jar (instead of entirex.jar as the documentation suggests).
Hi Douglas,
I really don’t know what I am doing, and am working with the barest minimum of experience in all of this.
When using ‘Generate Web Service from Software AG IDL’ in Workbench v7 I was able to specify a URL which appeared in the resulting wsdl as location=… I don’t know how or where to do this in Designer v8.
Regards,
Willie
Hi Willie,
the Web service’s URL has no meaning as long as the service is not deployed into a runtime where it is accessible. That’s why at service generation time a default URL is inserted (that actually points into the default WS-stack installation that comes with EntireX 8.2).
An easy way to generate, deploy an test a Web service starting from an IDL would be:
Now you can right click on the service archive (.aar) and from the “Web Services Stack” submenu chose “View deployed Web service”. This will display the service’s WSDL from the URL where it has been deployed to.
Additionally you can test your service as follows:
Hope this helps.
With kind regards,
Dietmar
Hi Dietmar,
Thank you very much for your advice, and apologies for my late reply.
Using Deploy Service gave an error which is far too long to transcribe here.
For the purposes of the current project (which of course has time pressures), we will stick with V7 of the Workbench and edit each xmm file to change the minOccurs from 1 to 0.
Thanks and regards,
Willie
