在哪里可以下载原始Java软件包并将其添加到我的项目中? [英] where can i download original java packages and add to my project?

问题描述

考虑以下情况，我正在受限的Java环境中工作，因此我没有javax软件包.但是我的项目严格需要这些软件包.

Consider the following situation, I am working in a constrained java environment and in this I don't have the javax packages. But my project needs these packages strictly.

该环境还允许我在自己的项目空间中添加新库.

Also the environment allows me to add new libraries on my own project space.

那么我有什么方法可以下载javax软件包并将其添加到我的项目中?如果可能的话，请列出执行此操作的步骤.

So is there any way i can download javax packages and add it to my project? If possible please list out the steps to do it.

对这个问题更相关. Google App Engine 具有自己的 java类白名单，可供使用.实际上，它错过了某些项目所需的某些课程.在这种情况下，是否可以将特定类作为库添加到我们的项目中?如果可以，我们如何获得课程文件?

To this question more relevant. Google App Engine has its own white list of java classes that are available for usage. Indeed it misses some classes that necessary for some projects. In these situations is it possible to add the specific classes as library to our projects? If so how can we get the class files?

推荐答案

好，您将所有Java 软件包放入名为rt.jar的jar中，该文件位于目录jdk_install/jre/lib/rt.jar中，该目录包含全部 软件包，也是javax.对于您的import来说，jar

ok here you go all java packages are within a jar named rt.jar which is in directory jdk_install/jre/lib/rt.jar which contains all the packages and yes javax too.. for your working import that jar

要import将该jar创建一个具有名称 lib的文件夹，并将该rt.jar及其所有api放入其中，然后将该文件夹与您的jar存档，就可以开始运行了.

To import that jar create a folder with name lib and place that rt.jar and all your api within it and then place that folder with your jar archive, and you are ready to run.
