Problem loading OJET application through Citrix Gateway

Sirish Reddy

We have an application built on Oracle JET, that needs to be accessed by external clients through Citrix Gateway. However, the application fails to load and we do not even see the login page. We just see the favicon on the tab header. Looks like none of the application resources are loading. Any help on resolving this issue is highly appreciated. Thanks.

Hi Sirish,

Looks like your application fails to bootstrap and load the necessary files / libraries.

Make sure the files/urls listed (/cvpn/.../SelfService/js/ojs/*.js) are accessible from the client maschine which runs the browser. I do not know a lot about the citrix architecture, so I am not sure the actual Citrix Client maschine is the one requesting the files or if it is more like an RDP where the remote maschine would run the browser and query the files.

The paths itself also look weird. JET files should usually be resolved from a URL where the files are hosted. Maybe the path you copied was the cut off version displayed by most consoles? In the console, try hovering the path and see if you can get the full URL.

I hope that puts you on the right track.

Kind Regards,

Philip

Thank you for the response Philip! I have tried to access the resources directly from the URL and get a 404 error.

I see all the jquery, require.js and the application related js files are accessible. However any js file that is inside the ojs folder fails to load....

-----This below resource loads fine-----

Hi Sirish,

Usually, the oj libraries are built at /js/libs/oj (not ojs). So my guess is that your require confiuration is not correct and it tries to interpret the 'ojs/ojbutton' require as a direct path instead of a library name which resolves to path /js/libs/oj/ojbutton.

The mapping should be in your (built , not source) main.js as something like:

function () {

  requirejs.config({

    baseUrl: 'js',

    paths:

      // injector:mainReleasePaths

      {

        knockout: 'libs/knockout/knockout-3.5.1.debug',

        jquery: 'libs/jquery/jquery-3.5.1',

       ...

        'regenerator-runtime': 'libs/regenerator-runtime/runtime',

      }

    // endinjector

...

If you use the Oracle JET tooling CLI (command line interface) to build your application, these paths will be generated from the path_mapping.json file during build.

So I think you should check the main.js and path_mapping.json to for the filepaths.

Kind Regards,

Philip

Edit: The relevant entry in the main.js in your case is for 'ojs', which tells requireJS where to load ojs from. E.g. if

ojs: 'libs/oj/v10.0.0/'

it looks for 'ojs/ojbutton' first in js/libs/oj/v10.0.0/ojbutton. If it does not find it it will try and treat 'ojs/ojbutton' as a direct path and load js/ojs/ojbutton.
