In case of a Windows machine, you could go to the control panel and click on Java Control Panel to find the location of the Java Cache.
In my case it shows: C:\Documents and Settings\user1\Application Data\Sun\Java\Deployment\cache
如果是 Windows 机器，您可以转到控制面板并单击 Java 控制面板以查找 Java 缓存的位置。
就我而言，它显示：C:\Documents and Settings\user1\Application Data\Sun\Java\Deployment\cache

In case of a Linux machine, I have it on :
如果是 Linux 机器，我有它：
/home/bakkal/.java/deployment/cache/
/home/bakkal/.java/deployment/cache/
where /home/bakkal is just my personal home folder.
其中 /home/bakkal 只是我的个人主文件夹。

The .jar was removed, if you want to run or decompile it, rename it with .jar
.jar 被删除，如果你想运行或反编译它，重命名它 .jar

Keep in mind that the location on windows has changed. It was different in java 6 (compared to java 5).
请记住，Windows 上的位置已更改。它在 java 6 中有所不同（与 java 5 相比）。

Unless you have a Very Good Reason(TM) you should basically not have to care about that as that is the job of Java Web Start to handle.
除非您有一个非常好的理由 (TM)，否则您基本上不必关心它，因为这是 Java Web Start 的工作。
If this is for locating the jar from insideyour own code, you can ask the class loader where it got the bytecode from. Given the security manager allows!
如果这是从定位罐子里面你自己的代码，你可以问的类加载器的地方，从得到的字节码。鉴于安全经理允许！
