For Windows 64, the 32-bit JDK is used for eclipse.

A 64-bit win7 software is written based on 32-bit eclipse and cannot be started.

A 32-bit JVM must be loaded.

Therefore, the 32-bit version is downloaded. Then add the path to the configuration file.

For example, I am-vmargs c: \ Program Files (x86) \ Java \ jdk1.7.0 _ 25

====================

At present, no matter whether the laptop or desktop memory is already the price of cabbage, memory configurations above 4 GB can be seen everywhere. I recently upgraded my laptop's memory to 8 GB. Naturally, I want to better support large-capacity memory and install 64 systems as necessary. According to my personal usage, I have not found any commonly used software that is incompatible with 64-bit win7.

Back to the topic, as a coder, the development environment must be built. In a 64-bit system, the most common is the choice of eclipse64 + JDK 64-bit. This is also the case in my notebook environment. The official website is as follows:

Eclipse: http://www.eclipse.org/downloads/ (currently the latest is 3.7, Which is indigo)

JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html (I chose jdk1.6.029) However, there are also many friends asked me 32-bit JDK can not be used, 32-bit eclipse? Of course. In fact, I also installed a 32-bit JDK in my notebook (it seems that the system compiled with Maven prompts JDK incompatibility. It seems that I cannot remember it ......), Java_home and other normal configurations. The 32-bit JDK is installed in c: \ Program by default.
In files (x86), you can point to java_home here. Besides, for 32-bit eclipse, if your java_home is configured with a 32-bit JDK, you can only use 32-bit eclipse by default. If you configure a 64-bit JDK and want to use a 32-bit eclipse, You need to modify the eclipse. ini file. In-vmargs, add the 32-bit JDK path, which is consistent with the path configured for java_home. For example:

-Vmargs c: \ Program Files (x86) \ Java \ jdk1.6.0 _ 29

Similarly, you should use 64-bit eclipse when Java _ home is configured with a 32-bit JDK.
