WSDL callOperation newbe problem

[michalg]

Hi,
Sorry if I am missing something obvious but as a SmartGWT and WSDL beginer I am facing the wall right now.

This is simple wsdl I generated:

<?xml version="1.0" encoding="UTF-8"?>

service.callOperation callback routine is never executed - no errors or other messages on the debug console.

Thanks for any help

Could you clarify what step the code is currently reaching - do you see your server being contacted, do you see a valid response from the server in the RPC tab? Do you see any JS errors and does the same thing happen regardless of browser?

[michalg]

Could you clarify what step the code is currently reaching - do you see your server being contacted, do you see a valid response from the server in the RPC tab? Do you see any JS errors and does the same thing happen regardless of browser?

Thank you for your time. I would try to clarify:
1) The code is reaching this line:

                 service.callOperation("hello", data, null, new WebServiceCallback() {
                     @Override
                     public void execute(String[] data) {
                         System.out.println("!");
                         Form.this.setValue("Answer", data[0]);
                     }
                 });

and goes on, but Callback is not executed.

2) Server is contacted - this is taken from Developer Console RPC tab:

0	/HelloGWT/js/sc/system/schema/schemaTranslator.xsl RPCRequest SUCCESS 10:21:40.156 812ms

1	/axis2/services/NewAxisFromJava.wsdl RPCRequest SUCCESS 10:21:41.062 219ms

2	http://localhost:8080/axis2/services/NewAxisFromJava RPCRequest SUCCESS 10:23:30.765 188ms

3) The following can be seen on the Developer Console Results tab (log messages):

10:20:51.921:INFO:Log:initialized
10:20:53.406:INFO:Log:isc.Page is loaded
10:21:40.187:WARN:VLayout:isc_OID_0:ignoring bad or negative height: auto [enable 'sizing' log for stack trace]

    XMLTools.$37c(_1=>Obj, _2=>"<?xml version='1.0' encoding='UTF-8'?><s..."[270], _3=>Obj)
    ** recursed on Class.fireCallback

All above in debug (hosted) mode.

4) 'Object doesn't support this property or method.' occures as JS error then deploying on IE7.

Thanks for the extra info. Can you post the actual response? What you posted before was mangled (invalid XML missing end tags).

Also, I think Firebug would give a different and perhaps better error report - what's the error message there?

[michalg]

Firefox Browser's JavaScript Console reports an error:

Hmm, from code inspection, that looks impossible, eg, the relevant line reads:

var passedXPath = resultType != null && resultType.contains("/"),

We'll see if this error can be reproduced with your WSDL, but you can almost certainly solve this by passing the resultType parameter to callOperation, and it seems like you'd want to do this anyway. It looks like you want to pass either "helloResponse" or "return".

[michalg]

Thanks.
Well, I did pass resultType "helloResponse" and "return" like this:

                 service.callOperation("hello", data, "return", new WebServiceCallback() {
                     @Override
                     public void execute(String[] data) {
                         System.out.println("!");
                         Form.this.setValue("Answer", data[0]);
                     }
                 });

and got the same JS error:
In hosted mode on console

on IE7:

Row: 707
Position: 193
Error: Obiekt nie obsługuje tej właściwości lub metody.
Code: 0

and on Mozilla (line 706):

_7.contains is not a function
http://localhost:8080/HelloGWT/js/sc/modules/ISC_DataBinding.js

MichalG
ps
'Obiekt nie obsługuje tej właściwości lub metody.' means 'Object doesn't support this property or method.'

[Isomorphic]

Well, this is quite odd. The crash you're reporting continues to appear impossible by code inspection, nothing has changed in this code recently, and callOperation is working everywhere else. Give us a couple of days and we'll attempt to reproduce the issue with your WSDL file.

[sjivan]

There was an issue in the SmartGWT callOperation API. (wasn't passing resultType). The fix is in SVN. Can you try building from SVN and rerunning your sample?

Thanks,
Sanjiv

With smartgwt.jar build from SVN I got:

See the docs for the resultType parameter - it should be a complex type or complex element, and "return" is not. However "helloResponse" is.

[michalg]

OK, but when passing resultType="helloResponse":

[sjivan]

I'll try running your sample locally to see whats going on.

Sanjiv

[sjivan]

Can you try updating and building from SVN? I haven't had a chance to reproduce and verify your sample but I checked in a change that should help resolve your issue.

Let us know how it goes..

Thanks,
Sanjiv

[michalg]

I have checked out v213 from SVN. Although thre are no JS errors now, the execute() method is never fired:

    class Form extends DynamicForm {
         public void callService() {
             if(service == null) {
                 SC.say("Please try again in a moment  - still loading web service descriptor");
             } else {
                 setValue("Answer", "Working...");
                 Map data = new LinkedHashMap();
                 data.put("name", getValueAsString("Test"));
                 service.callOperation("hello", data, "helloResponse", new WebServiceCallback() {
                     public void execute(String[] data) {
                         System.out.println("!");
                         Form.this.setValue("Answer", data[0]);
                     }
                 });
                 System.out.println("data="+data);
             }
        }

Neither "Answer" widget is updated and System.out.println("!") printed on the console.
