oBrowser PDF

[malkishtini at gmail.com]

Hi all,
Just sharing what I've learn this past weekend about oBrowser and the JSClientbridge in case it helps someone in the list.

After deploying our Studio client app(that runs the oBrowser) and the web app (that runs the jsclient forms) to testing servers, where the client app is installed on a different server than the studio web app, I started getting CORS policy error:

oBrowser (file:///C:/Program%20Files/Omnis%20Software/OS%2010.22/htmlcontrols/jsclient_bridge/scripts/core.bundle.js:3) Access to XMLHttpRequest at 'file:///C:/Program%20Files/Omnis%20Software/OS%2010.22/htmlcontrols/jsclient_bridge/themes/default.css' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, d

The solution was by adding the two attributes below to the "cefSwitches" section in the config file of the Studio client app that runs oBrowser.
"obrowser": {
        "cefSwitches": [
            "allow-file-access-from-files",
            "disable-web-security"
        ],

I was testing on Windows 2019 servers and IIS.

Hope this info helps someone.
Best regards,
Mayada

Hi Doug,

"locale": “es-ES”,

in config.json did the job.

I’m beginning to use oBrowser but requires a learning step but seems very powerful.

I will try to deepen with oBrowser and will take a look to cefSwitches.

Thank you Doug,

regards

xavier
