A DESCRIPTION OF THE REQUEST :
When we deploy applets the jars are downloaded on client machine in the directory ..\Documents and Settings\Username\Application Data\Sun\Java\Deployment\cache\javapi\v1.0\jar when clients access to the pages.

First, it will be a very good thing to clean this directory sometimes as it grows always and can become a problem on client's machines due to space usage.

Second, if a package had some patches and versions evolutions all these versions remain in this directory what implies that often not the latest deployed version is executed in the browser. So we have to support clients to show them what has to be cleaned.

JUSTIFICATION :
This is necessary as clients should not have to clean such files to avoid abnormal space disk usage for one applets application and therefore ensure that the latest version is the one executed.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When the same packages are downloaded for execution, existing ones should be deleted in order to execute only the latest version available.
ACTUAL -
Often the client's expected corrections or enhancements are not present when executing the applets page because it is not the latest version that is executed. We have then to support them to clean up the directory in order to ensure latest version execution.

---------- BEGIN SOURCE ----------
Any applets package deployed in a web server and accessed by a web browser (mainly IE).
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Go to the directory with explorer and delete the files.
