Problem with web service

Hi,

I try to integrate a web service into my VC model. I have defined the WS, and the corresponding methods appear in the Data Service. But if I try to test the WS I get an error "Portal request failed (could not execute Web service operation)". There is no entry in any log file about the problem. Any idea ?

Regards, Christian

    Check your proxy:

    Hi,

    the proxy settings are fine. Otherwise the WSDL file could not be loaded.

    Hi,

    I have the same problem. Usually, when I include a webservice first it works fine but after a while suddenly it appears that failure without any reason. I also tried to find some hints in the logs but no success.

    Could it be a problem with the webservice system integration of visual composer. I heard something about that in earlier versions of vc. Is this problem still existing in the latest version of vc (NW2004s SP9)? Or could it be a problem of authentication?

    Any help is appreciated. Thanks in advance.

    I have the same issue. I launched the service I know the service has been executed and sent back some return information in a basic structure, but Visual Composer can not treat the return information.

    Really funny

      Hi,

      we could avoid the problem when we disabled the user authentication of the web service. So it is not necessary to enter user credentials when setting up a new WS system via VC.

      Sure, for security reasons this is no solution. But just for testing WS connections with VC applications it is helpful.

      By the way, before disabling the user authentication I've also traced the VC request to the WS system. For me it seemed when using user authentication sometimes the system configuration (?) switches to "Guest" user mode and then WS access fails. Why this is happening I don't understand. Maybe somebody has heard of this.

    Hi all,

    Same problem..

    I've developed a simple web service which returns a LinkedList object with some information. I've deployed it and works fine when I test it in the Web Service Configuration section of the J2EE Engine page.

    So, I create a Web Service based system in my Portal, test it and everything goes fine.

    In VC I used that WS to obtain the data, but It didn't work.

    If I test it, I get an error.

    I have created an iView which, aparently, should present a Table with the data returned from the WS, but this table is empty when I run the iView...

    Has anyone solve this kind of problems?

    Thanks a lot,

    Alberto.

    PD: I've defined another Web Service based system in VC and still doesn't work..
