This report is sent with the assumption that having java in $PATH should
allow konqueror to run Java without more configuration.
After installing a JRE/JDK with, for example, java-package, konqueror
won't run Java applets, for example the one on
http://www.java.com/en/download/help/testvm.xml
Going to Settings -> Configure Konqueror..., Java & JavaScript will show
Path to Java executable, or 'java' as "java". One would expect it to
work, but it doesn't.
However, a simple but illogical
procedure will make the applet work:
Open Konqueror
Go to the test page
Go to the Java & JavaScript config
Change basically any setting and apply.
Refresh the page.
For example, one could go to the settings, disable "Enable Java
globally", Apply, reenable it, "OK", and then reload.
This could generate the following diff in konquerorrc:
$ diff konquerorrc.back konquerorrc
3a4,23
5c25

"Writing the defaults" to konquerorrc is enough to change konqueror's
behavior.
