I’m new here and have a problem.
First of all, I’ll describe the environment.
My ex-colleague integrated the JXBrowser version 7.37.0 into our software (= Java based)
in order to establish a connection to a document management system (DMS) via a link.
The DMS is operated on the customer’s intranet.
The users log into the DMS with their Windows user.
The DMS has installed so-called “WEB clients” and certificates on the clients.
These WEB clients start Outlook on the client in order to send the documents by email.
Only the message appears that the browser should be reloaded.
The DMS has switched from http to https.
The problem that now occurs is that the WEB clients no longer work and therefore Outlook cannot be started.
I would be very happy and grateful if someone could give me a tip on my issue.
Here is the source code of my test program:

After researching on the Internet, I found a few things and implemented them in a test program so that I and the customer can test them beforehand.
I have implemented the following methods:
- VerifyCertificateCallback
- CertificateErrorCallback
- disallowJavaScriptAccessCookies
- SelectClientCertificateCallback
- AuthenticateCallback
- OpenExternalAppCallback
- enablePlugins
- enableJavaScript
- enableLocalStorage
- allowRunningInsecureContent
- allowJavaScriptAccessCookies
- allowJavaScriptAccessClipboard
When testing, we noticed that the VerifyCertificateCallback is always executed and the DMS server certificate cannot be verified.
