如何删除正在执行的jar文件 [英] How to delete a executing jar file

问题描述

我创建了一个应用程序，其中基于一个操作，它修改了jar中的属性文件。

我可以创建一个新的temp jar随着更新的变化。但是不能将jar文件重命名为现有的jar文件名。

任何人都可以建议任何操作或建议来删除jar（Currently Executing），并将temp jar到那个名字？

我已经为应用程序做了：

解决方案

可能你需要编写一个自定义类加载器（扩展ClassLoader），使您可以加载/卸载该jar。如果你可以卸载jar，你应该可以删除这个jar。

我可以动态卸载并重新加载（其他版本的相同）JAR吗？

I have created an application, in which based on an operation, it modifies the properties file inside the jar.

I'm able to create a new temp jar with the updated changes. But can't rename the jar file to the existing jar file name. Since it is running, I am not able to delete and rename it.

Can any one suggest any operations or suggestions to delete the jar (Currently Executing) and rename the temp jar to that name?

I have doing for the Application: http://java.net/projects_tags/jeazyprops

解决方案

May be you would need to write a custom class loader(extending ClassLoader) which enables you to load/unload the jar. You should be able to delete the jar if you can unload the jar.

Can I dynamically unload and reload (other versions of the same) JAR?
