Question

I am just learning Java applets. When I changed my code, it doesn’t update if I refresh the page, but it does when I close the entire browser and open it again. I’m using eclipse as my IDE.

Is there some setting I’m missing? Or is the only way to do it?

Answer 1

You can enable the Java Console, which includes several useful commands. In particular, x: clear classloader cache may be helpful.

c:   clear console window
f:   finalize objects on finalization queue
g:   garbage collect
h:   display this help message
l:   dump classloader list
m:   print memory usage
o:   trigger logging
p:   reload proxy configuration
q:   hide console
r:   reload policy configuration
s:   dump system and deployment properties
t:   dump thread list
v:   dump thread stack
x:   clear classloader cache
0-5: set trace level to 

Addendum: The Java Console is sometimes the only way to see certain problems early in the applet life cycle, but a hybrid approach is sometimes convenient. You can use your IDE to debug the program as an application and then deploy it as an applet or via Java Web Start.
