Browser (Chrome, IE, Firefox) with embedded Java?

Question

Java

For accountants, it is required to submit reports through tax systems, they use Java for authorization by RSA key - this is a certificate file.
Very often Java does not start correctly or gives an error during work.
The question is - is it possible to create a browser + Java assembly for a universal solution to problems with access to the tax reporting system?

Answer 1

Understood nothing. How, what, where it connects... Formulate the thought correctly.
If you have a separate Java application that is launched through AppletViewer using the JVM (AppletViewer + JVM) as a standalone application, then you need to add a couple of lines here so that the Java application opens in the JVM + Browser bundle. Then it will open through the browser.
However, not all browsers support applets.
JVM + Browser = The program is launched through the browser.
JVM + AppletViewer = The program runs as a standalone program in a separate window.

Answer 2

Java applets are not supported in Chrome 42+ because plugins implemented via NPAPI are not supported, and the Java plugin is implemented only for it, and is not ported for PPAPI.
