Hi there Gurus of BB development,

I make a SOAP call with kSoap2, it throws an exception because my code is bad, then I fix my code, I call envelope.getResponse() or envelope.getResult() and it works... I get the data back that I am expecting.

So I modify the code I copy and paste the working code into another method, change the web method to call.

I have been assured that this web method works fine in other languages on other platforms other than Blackberry.

I have one method that calls each of the methods that make SOAP calls.
The original method still works and the new method throws no exception, returns no data. I just get anyType{} from envelope.getResponse()...
I want to blame the web service but a response of "anyType{}" doesn't give me much to work with.

Do I need to reset anything between calls...?
It is wierd that I don't get an exception but then I get nothing back also...


Edit: Perhaps ignore this... The network people mentioned something about host protection system swallowing connections, preventing buffer overflow attacks, mumble, mumble, mumble, preventing denial of service, ....


Meanwhile I've been pulling my hair out...

Hi,

Can you post a code fragment? Maybe it helps.

[goulamass]

Hum your Web service is in?? .Net?? Java??...

Because some times there is comptability problem

Post the call you make and the wsdl of your web service if you want we look at.

Here envelope.getResponse(); gives me anyType{}.....

Post the call you make and the wsdl of your web service if you want we look at.

Various web services called by this application, .NET (C#) and PERL on Linux.. Note the envelope.dotNet = true; ...

The WSDL is larger than can be posted here.



Cheers,

If you want to debug you may look on the transport to see what is your request and what is the answer you get.

Put this after the call :

System.out.println("Request \n" + transport.requestDump); System.out.println("Response \n" + transport.responseDump);

I am debugging on the device.
I changed teh System.out.println() to Dialog.alert() and got null in both cases.

I still suspect that there is a network issue involved somewhere.
We have pretty extreme security.

So in the try catch wrote in the catch :

catch(Exception exception)
{
System.out.println("... itz throwing exception..." + exception);
System.out.println("Request \n" + transport.requestDump);
System.out.println("Response \n" + transport.responseDump);
}

So you will see what is the exception throw

There is no exception thrown
That is what has been pissing me off all along.
No exception thrown and no repsonse, and I just get null or anytype{} back.

Whats more, the first call is effectively the same code with another method of the same serviced called. First call succeeds, the second call doesn't throw an exception but returns nothing... And the web service has been around for a long time and is supposed to work fully on other platforms.

[goulamass]

Hum so the problem comes probably from the WS.

Check it from anothers platforms.

Or modify it that it sends back data you send to see if it receives the good data

[PymbleSoftware]

Here are SOAP request/response for the LogonUser call:

 

Request:

<?xml version="1.0" encoding="utf-16"?>

<soap:Envelope xmlns:soap=" URL " xmlns:xsi=" URL " xmlns:xsd=" URL ">

  <soap:Body>

    <LogonUser xmlns=" URL ">

      <Username> #####  </Username>

      <Password> ##### </Password>

      <SystemID>6</SystemID>

      <SessionID>7767358e3e684ea689b5d39a3d8592ba633607050626718922</SessionID>

    </LogonUser>

  </soap:Body>

</soap:Envelope>

 

Response:

Cache-Control:private, max-age=0

Content-Type:text/xml; charset=utf-8

Date:Mon, 27 Oct 2008 00:51:58 GMT

Server:Microsoft-IIS/6.0

X-AspNet-Version:2.0.50727

X-Powered-By:ASP.NET

 

<?xml version="1.0" encoding="utf-16"?>

<soap:Envelope xmlns:soap=" URL " xmlns:xsi=" URL " xmlns:xsd=" URL ">

  <soap:Body>

    <LogonUserResponse xmlns=" URL ">

      <LogonUserResult>0c8efd5ab4e54a729a5215ddcd3567c8633607051187428986</LogonUserResult>

    </LogonUserResponse>

  </soap:Body>

</soap:Envelope>

Works from C#...

"Or modify it that it sends back data you send to see if it receives the good data"


Oh, and I can not modify the Web service for what it is sending back. I am testing against a production machine with tens of thousands of users logged in.

Just create a new function in your web service.

For example :

String helloWord(String a)
{
return a;
}

Can you simply add it??

On a live prodcution machine with tens of thousand of users logged in where I don't have access to the machine or even know which machine the load balancer connects me with? No, I'd be shocked if anyone would give me approval and anyway the 1st call always works. There is no effective QA environment and there is no signed SSL certificates on the test servers.



RR

[PymbleSoftware]

A new signed cert appeared on the QA test servers..

Someone inspected what was going over the wire with tcpdump, Wireshark or ethereal or whatever and the difference between C# calls and the Blackberry calls is that the Blackberry code has: <Username i:type="d:string"> and the C# code merely has <Username>

Somehow, the WS barfs on that type info.. :roll:

Solved, I hope.
Now to figure out how to turn that off with the Blackberry.

RR.

[PymbleSoftware]

bump...

I tried every option I could find on the SOAP objects and envelopes and stuff and I can not seem to be able to turn that off... i.e. Make <Username d:type i:string> just simply <Username>

Ideas anyone, it is due tommorow and I am not a SOAP expert.

RR.

[PymbleSoftware]

I posted in a general Java forum. Looks like I am not the only one who has problems with kSoap2.

Problems with a complex datatype in a webservice - Java Forums

I think I have to parse the body string and take out teh typeinfo before sending it.
Anyone done this...?

Other solutions..?
