Can we set a default browser-tab icon for applications running under glassfish server?
Here is the solution:
Simply add the favicon.ico icon to the docroot folder of glassfish, and restart.
If it did not work, then, you have to define the 'ico' extension mime-type in your default-web.xml glassfish file, this is done by adding the following code on the file:
<mime-mapping>
<extension>ico</extension>
<mime-type>image/vnd.microsoft.icon</mime-type>
</mime-mapping>
