解压缩JDK安装程序时没有“src.zip”

Question

I have followed this procedure : How can I get the latest JRE / JDK as a zip file rather than EXE or MSI installer? . In order to get JDK w/o admin rights. However, I still miss the source archive "src.zip".

When I open the installer with 7-Zip, it only shows "tools.zip" file. Here is the command-line output:

C:\Users\mlogan\Downloads>7z.exe l jdk-7u45-windows-i586.exe

Have you any idea on how to retrieve the source archive ?

Answer 1

According to the latestest answer by Piero Ottuzzi in his post http://www.brucalipto.org/java/how-to-create-a-portable-jdk-1-dot-8-on-windows , Oracle seems to no longer include src.zip from update 45. You could always use tools.zip to have a portable JDK.

Steps to follow on Windows to have a portable JDK:

1. Download the installer, eg. jdk-8u51-windows-x64.exe, into a folder, eg. "downloads", that contains 7z.exe.

2. Extract tools.zip from the installer with 7-Zip: open a command prompt and type

    D:\\downloads>7z x jdk-8u51-windows-x64.exe 

3. Extract the content of tools.zip to a folder, say "jdk", with 7-Zip: type in the command prompt

    D:\\downloads>7z x tools.zip -ojdk 

4. Move to the folder jdk and transform .pack files to .jar files: type in the command prompt

    D:\\downloads>cd jdk D:\\downloads\\jdk>for /r %x in (*.pack) do .\\bin\\unpack200 -r "%x" "%~dx%~px%~nx.jar" 

The folder jdk is the wanted portable jdk. To test it, type in the command prompt:

D:\downloads\jdk>.\bin\java -version

You would get

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

Answer 2

正如@PeterLawrey建议的那样，最好的方法是使用Linux发行版。

Answer 3

You can extract src.zip by following the steps mentioned below.

Note: Steps are mentioned for jdk-7u80-windows-x64.exe . Steps for JDK7 and JDK8 (for both 32bit and 64bit) are similar.

Step 1

Execute the offline installer jdk-7u80-windows-x64.exe . Let the setup screen appear. Don't press the Next button.

Step 2

Now now in file explorer go to the directory

C:\Users\UserName\AppData\LocalLow\Sun\Java

where UserName is replaced by actual user name.

Note: For JDK 8 use the directory

C:\Users\UserName\AppData\LocalLow\Oracle\Java

Now the MSI and CAB files for JDK 7u80 64 bit installation will be in the directory jdk1.7.0_80_x64 .

Note: For 32 bit JDK 7u80 installation the corresponding directory will be jdk1.7.0_80 .

Step 3

Copy this folder to some other suitable location. Now cancel the JDK installation.

Step 4

Now in the copied folder you will find following files:

1. jdk1.7.0_80.msi - MSI for JDK installation.
2. sj170800.cab - Contains files required for stand alone JRE installation.
3. ss170800.cab - Contains file src.zip .
4. st170800.cab - Contains file tools.zip .
5. sz170800.cab - Contains file COPYRIGHT .
