我工作的一个应用程序/产品，它是32位和客户希望将其改为64位Java。 请解释一下什么样的变化，我需要做的，使产品开始支持64位的Java。

I am working on a application/product which is 32 bit and client wants to change it to 64 bit Java. Please explain what changes I need to do, so that product start supporting of 64bit java.

应用程序是JAVA，JSP，Servlet的。 OS支持LINUX，WINDOWS

Application is on JAVA, JSP , Servlet. OS Supporting LINUX, WINDOWS

推荐答案

使用应该被编译为使用64位架构所有本地code。 爪哇code本身是从一个32位架构到64位architercture便携，尽管这是architercture依赖性非确定性问题可以变得可见。例如，非线程安全的code可以表现不同的方式在不同的平台。

All native code used should be compiled for the 64-bit architecture you use. Java code itself is portable from a 32-bit architecture to a 64-bit architercture, though non-deterministic issues that are architercture-dependent can become visible. For instance, non-thread-safe code can behave differently on different platforms.
