Clear the Java Web Start cache using a command line in Microsoft Windows 10, 8, 7, Vista, or XP. When you access a Java application, it is downloaded to a cache on your computer. This allows for faster access. Sometimes caching can be a problem, especially if you are in a development environment.
Option 1: from the command line
Fortunately, Sun provides a command that allows you to clear the Java Web Start cache. This is how it runs:
- Hold the Windows key and press «R”To display the Windows Run dialog box.
- Paste “javaws -uninstall“Without quotes, then select”Correct«.
You should see a pause and then the cache will be cleared. No notification will appear to inform you that the order was successful.
You can also run this same command from a classic command prompt.
Option 2: from the Java control panel
- Opened “Control Panel«, Then select»Java«.
- From “general«, Select the»Settings …“button.
- Select «Delete files …«.
- Make sure the “Cached applications and applets»Is selected.
- Select «Correct«.
