Hi We have migrated to Appeon PB 2019 R2(Build 2328) a year ago. I am now trying to explore new features. First one was calling web service without using old proxy webservice object so when I declare

AppeonWebServiceComponent caller

I get compile error 

C0001: Illegal data type

 

Which library I am missing?

Hi Amit,

Are you calling a SOAP or REST Web service?

If SOAP, are you using HTTPCliet object and following this tech article?  https://community.appeon.com/index.php/articles-blogs/tutorials-articles/2-powerbuilder/236-call-soap-web-services-using-httpclient-object

By the way, I recommend upgrading from R2 to R3.  R3 is a long-term support version and it has many new features.  https://www.appeon.com/developers/powerbuilder-release-history.html

 

Best regards,
Armeen

I am trying to use REST API. I haven't tried SOAP with HTTPClient yet since it's migrated from old and working fine with web proxy.

 

Yes migration to R3 is also planned in next couple of months.

To call a REST API you should use the RESTClient object.  Also, REST APIs usually return JSON formatted data, and for JSON format you need to encode/decode URLs and encode/decode blob data types.

I recommend carefully going through the REST Bootcamp, study the code examples, etc.

Thanks. I will read thru before asking more question.

What is AppeonWebServiceComponent  ? Can it not be used?

Are you using PowerBuilder or PowerServer? I assumed PowerBuilder because you posted in PowerBuilder Q&A instead of PowerServer Q&A. For PowerBuilder client/server projects, you should NOT use AppeonWebServiceComponent. That is something for PowerServer 2020 and older versions. PowerServer 2021 and newer support directly calling Web Services using HTTPClient or RESTClient.
