Creating a Sample OpenROAD Server Application with JSON-RPC Support

[Achini Lankage]

Hi,

I'm currently facing a problem while creating testapp.json using the JsonConfig4App utility for the “add” 4GL procedure which has mentioned in the link below.

https://docs.actian.com/openroad/6.2/index.html#page/ServerRef%2FCreating_a_Sample_OpenROAD_Server_Application_wi.htm%23 

 

I also tried running the image given at Github and it is giving me a w4gl error saying that the external library needs to be registered. I'm not sure if I missed any step instructed in the documentation.

It doesn't compile the application as well when I import it to the workbench.

If anyone can help me with this process would be really appreciated.

Thanks in advance

Achini.

Hi Achini

 

What exact OpenROAD version are you using (see first line of the trace window)?

Note: All the JSON (and JSON-RPC) support stuff was introduced in some patch (I recommend to use the latest patch, e.g. 15567), the JsonArray (system) class is one of them.

You do not need to download and import/build the JsonConfig4App utility from GitHub – just use the one provided with your OpenROAD installation.

See this tutorial video: https://www.youtube.com/watch?v=tpPatQavMPQ

 

If this still doesn’t work, could you provide the signature (name, return type, parameter types/names) for the 4GL Procedure you want to call via JsonRpcRequest()?

 

Regards,

Bodo.

Thank you very much for the prompt reply Bodo.

I am using the exact example given in the documentation just to understand the basic process.

Anyways the OR patch that I am using is p15017.

Is there any link that can refer to download the latest patch 15567?

I checked the official Actian site for downloads it provides me the option like the screenshot mentioned below. (openroad-6.20.15068-win-x86_64-eval-b)

Thanks in advance,

Achini.

Hi Achini,

 

I see that you tried the (old) Evaluation Edition.

Patches are available on the download site (https://esd.actian.com) for OpenROAD Enterprise Editions only.

E.g. there is patch 15567 for the 32-bit Windows version  and patch 15568 for the 64-bit Windows version of OpenROAD.

See https://esd.actian.com/platform/Windows_64-Bit/Actian_OpenROAD/6.2/OpenROAD_6.2.0_Patches

You’ll need a valid Service portal login for downloading the patches (for the version you have licensed).

 

You could also try the OpenROAD 11.1 (64-bit only), which contains all the features for 6.2. patches.

 

In order to get an evaluation license contact sa...@actian.com.

 

Kind regards,
