我希望通过复制Java文件夹的内容并设置环境变量来确保一切都能正常工作。
我通常在虚拟机中运行安装程序，压缩\java文件夹内容，回到虚拟机的快照，然后解压缩压缩文件。
我找不到一个地方有最新的JRE / JDK压缩文件…
http://java.sun.com/javase/downloads/index.jsp
http://download.java.net/jdk6/
另外，假定sun的exe安装程序只是解压缩整个文件，而不会弄乱注册表、环境变量等等，这是否安全?

从http://www.processing.org/download/下载Processing应用程序。zip文件包含一个名为java的文件夹。它包括JDK 1.6.0_32(版本检查于19/02/2013)。

The Process described by Igor and CharlesB Works to me, since IDE's like NetBeans and Eclipse permit specify the location of the JDK, even software like Apache Tomcat (the ZIP Distribution) use BASH - FILES to set it up (then specify the JDK location using relatives URI). I Have a USB-HardDisk With NetBeans, Eclipse, Apache Tomcat working with a JDK in "portable mode". I Had a way to extract a copy of the JDK from the installers files: Install it, Copy it in other place and then uninstall it. A dirty way to extract it, but was successfull. The place to put EXTRA - LIBS was: %PLACE_WHERE_JDK_ARE%\jre\lib\ext
不幸的是，JDK不能作为可移植的ZIP文件提供。但是，你可以遵循以下步骤:
Create working JDK directory (C:\JDK in this case) Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe) Download and install 7-Zip (or download 7-Zip portable version if you are not administrator) With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10 extrac32 111 Unpack C:\JDK\.rsrc\1033\JAVA_CAB10\tools.zip with 7-zip Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10\tools\ for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all .pack files into .jar files) Copy all contents of C:\JDK\.rsrc\1033\JAVA_CAB10\tools where you want your JDK to be Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.
得到广泛好评的答案很好，我已经用了很长一段时间，以这个bat文件的形式:
@ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
SET ROOT=%cd%
REM Get the tools.zip from the innards of the installer
7z e *.exe .rsrc/1033/JAVA_CAB10/111
7z e 111 7z x tools.zip
REM Extract all
7z x -aoa tools.zip -ojdk
del tools.zip
del 111
REM Searching directory structure from root for subfolders and zipfiles.
FOR /F "delims==" %%d IN ('dir /ogne /ad /b /s "%ROOT%"') DO (
echo Descending into %%d
FOR /F "delims==" %%f IN ('dir /b "%%d\*.pack"') DO (
echo Extracting "%%d\%%f"
REM Extract all packs into jars.
jdk\bin\unpack200 -r "%%d\%%f" "%%d\%%~nf.jar"
)
)
ENDLOCAL
pause;
它需要访问7zip的路径，并且必须在你选择的JDK的文件夹中运行(它会找到它，因为上面有*.exe)。
在8u144上也能用，我猜在8u20上也能用。
创建目标文件夹，您可以RWX(例如C:\jdk8) 从Oracle下载jdk exe(例如:jdk-8u72-windows-x64.exe) 将其中的tools.zip解压到目标文件夹中 在cmd.exe中运行: cd C: \ jdk8 在(x / r % * .pack)。\ bin \ unpack200 - r“% x”“% ~ dx % ~ px % ~ nx.jar”
这个解决方案也适用于没有Admin权限的JDK 8。
