#16 Visualization in an applet

[Anonymous]

Question :

Hello,

I use the tool infovis in order to visualize a graph in
an applet.
Initially I implemented all the code in a normal
application.
Now I try to transform it into an appplet.
I meet certain concern the filling of the basic table
"52weeks.reduced.extended.tqd" into the code.
The applet apparament does not arrive at reading the
table....
I tested several methods but I met that failures.

Here the error during the launching of the applet

[aperar01@scinfe142 VISUALISATION]$ appletviewer
-J-classpath
J/usr/local/src/infovis-0.8alpha2/build/examples.jar:/usr/local/src/logging-log4j-1.2.9/dist/lib/log4j-1.2.9.jar:/usr/local/src/colt/lib/colt.jar:/usr/local/src/archives/antlr-2.7.5.jar

Hello,

I think the way I load resources for rendering the
items is not secure
so applets won't let me load them that way.
I have to take a closer look at accessing resource
files from inside an
applet.
I'll take a look soon and let you know. MEanwhile,
could you add a bug
report on sourceforge.net to remind me?

Thanks in advance,
