javaws clearing cache via commandline

Hello,

According to the Sun javaws Command Line documentation*, the following
line should clear the user cache and exit when done, silently, while
supressing the splash screen and exit when done:

javaws -Xclearcache -silent -Xnosplash

This line appears to clear the cache, but does not supress the splash
screen, nor does it exit when finished, nor does it run silently.

I hit Post too soon. so....

Basically, the above doesn't function as proper. Is there another way
(using javaws) to clear the cache? I'm wondering because it would be
terrible to have to enumerate sub-directories and then delete the
jsi.cache dir if there's already functionality in javaws.

Any input would be appreciated.

Thanks!

Matt

you can type Javaws.exe -viewer and try deleting via the gui.

I'm looking to script this for a scheduled task, so my goal is clear
the cache from the commandline.

Sorry I sent this to your email address by mistake...

Hate to say this but it worked as designed for me. I am running
JDK.5.0_06. I did not try to use -Xclearcache because it said I did not
have the privileges to do so. I don't feel like looking that up.

javaws -silent -Xnosplash test.jnlp

ah hah... i guess -Xclearcache does "work," but gives me the following
error:

"An error occurred while launching/running the application.
Category: System Configuration
The current user does not have write access to the cache."

The exception is as follows:
"JNLPException[category: System Configuration : Exception: null :
LaunchDesc: null ] at com.sun.javaws.Main.main(Unknown Source)"

I am logged on as a local administrator while trying to run the
command; and I definately have write the ability to write to the cache
directory (is this what they mean by cache?). This seems strange.

Any ideas?

Thanks,

Matt
