Web service strange behaviour

maxcoros · July 10, 2018, 8:48am

Hi, I’m still working on the web service, now I have another problem. My WS must be accessed from a client developed by another person. Attached there are the wsdl generated by the WS, the SOAP xml file generated according with wsdl and a SOAP xml that is accepted by the WS.

xmlfiles.zip (3,4 KB)

The problem is that the xml file generated in according with the wsdl isn’t accepted from the WS.
As written in the WSDL the arrays must be serializated in:

    <VisitDate>
      <VisitDate>20180202</VisitDate>
      <VisitDate>20180209</VisitDate>
      <VisitDate>20180216</VisitDate>
     ...
      <VisitDate>20180706</VisitDate>
    </VisitDate>

but the WS accept the arrays written in the following way

<VisitDate>20170817</VisitDate>
<VisitDate>20170907</VisitDate>
<VisitDate>20171005</VisitDate>
...
<VisitDate>20180411</VisitDate>

I don’t understand why.

Could you help me?

that person tried to update his client according to your wsdl ?

maxcoros · July 10, 2018, 11:10am

Yes but as I told in the previous message when it use the wsdl the xml is generated in that way
< VisitDate>
< VisitDate>20180411</ VisitDate>
….

</ VisitDate>

If i try to import it with delphi and use standard delphi components I have the same problem, i must streep away the first < VisitDate> item. And according with the wsdl the right way is that is shown above.

EvgenyK · July 10, 2018, 11:17am

why they can’t generate xml according to your wsdl?
btw, you can put code/xml as is between ``` like

```
<VisitDate>
```

maxcoros · July 10, 2018, 11:21am

the code generated using the wsdl produce the “wrong” xml.

 <VisitDate>
    <VisitDate>20180216<\VisitDate>
   …
 <\VisitDate>

all the arrays are serializated in that way, but the service don’t accept them. I don’t understand why the service generate a wsdl but accept a different input.

EvgenyK · July 10, 2018, 12:11pm

can you create a simple testcase, pls?
your previous one contained AV…

maxcoros · July 10, 2018, 12:21pm

Sure the test case is the same that you have alredy seen. the Test client application use the wsdl as created from the service and use standard delphi components and generate a xml like described previously.

(clikking on test 2 button give an error in deserialization of the array INR)

WS Test.rar (362,4 KB)

EvgenyK · July 10, 2018, 12:25pm

can you fix AV in project?

for example


function TZEUSWS.CreaArrayDistribuzione(Distribuzione : String) : DailyDosage;
var i : Integer;
    ADistribuzione : Array Of Integer;
begin
  i := 0;
  while length(Distribuzione) <> 0 do
   begin
    Result.Add(StrToInt(copy(Distribuzione,1,pos(';',Distribuzione) - 1)));
    Delete(Distribuzione,1,pos(';',Distribuzione));
   end;
end;

here result is nil so you do

nil.Add(StrToInt(copy(Distribuzione,1,pos(';',Distribuzione) - 1)));

maxcoros · July 10, 2018, 12:35pm

I’m sorry but I don’t understand what I must do?

if you run the ws and run the testclient application when you click on test 2 button you can see what appen.

EvgenyK · July 11, 2018, 4:16am

your testcase contains errors, for example, in TZEUSWS.CreaArrayDistribuzione method you missed line like result := DailyDosage.Create; and it causes problems in run-time. I wonder how your testcase worked …

maxcoros · July 11, 2018, 6:51am

Simply because that portion of code isn’t called before the error. I.e. the deserialization error occurs before that that code is called.
Have you clicked on the test2 button?

maxcoros · July 11, 2018, 8:05am

As you have requested I’ve corrected the “error” but obviously the deserialization error is still here

WS Test new.rar (366,5 KB)

This is the error that comes up when I click on the “Test 2” button, as you can see the INR array is deserializated in the wrong way. (you must use the testclient application to get the error)

it works for me:

I see that the code that you have sent back to me works… the question is what have you changed? I’ve tryed the code that I’ve sent to you and it don’t work… where is my fault?

EvgenyK · July 11, 2018, 12:41pm

I’ve removed SOAP attributes. I’ve posted this RODL earlier

maxcoros · July 11, 2018, 12:52pm

Yes I’ve seen but now when I try to get the wsdl from the service I receive the following error:

i’ve put inside my browser http://localhost:8099/SOAP

{3B9B27D4-8858-45CB-8941-D7822196FCFE}EResNotFoundResource RODLFILE not found

I’m going really mad…

EvgenyK · July 11, 2018, 12:54pm

remove/comment {$undef RO_RTTI_Support} in ZEUSWS_Impl.pas.
I’ve used it for generation results from RODL-based server

maxcoros · July 11, 2018, 1:53pm

thank’s for your help finally it’s works. Could you explain to me why with soap attributes the service don’t work?

EvgenyK · July 11, 2018, 2:03pm

these attributes are mainly used for connecting RO client to 3rd party non-RO soap services.
RO client and RO server can perfectly work w/o them.

maxcoros · July 11, 2018, 2:06pm

Understood, but I as told before now there is another developer (another company) that must build a client for the WS, and he don’t use RO, there is going to be troubles?
