推荐答案

Tomcat的RUNNING.txt 表明Apache Tomcat需要Java Standard Edition Runtime Environment（JRE） ） 跑步。 JRE的最低版本取决于Tomcat的版本：对于Tomcat 6.0，它是Java 5，对于Tomcat 7.0 - Java 6.

Tomcat's RUNNING.txt which you can find in the root of the bundle states that Apache Tomcat requires Java Standard Edition Runtime Environment (JRE) to run. Minimum version of JRE depends on the version of Tomcat: for Tomcat 6.0 it is Java 5, for Tomcat 7.0 - Java 6.

但是您也可以使用JDK，因为你可能知道，它包括JRE（链接）。唯一的区别在于环境变量的配置。如果使用JRE，则应设置JRE_HOME，如果是JDK - JAVA_HOME。阅读 RUNNING.txt 了解更多详情。

However you can also use JDK because, as you probably know, it includes JRE (link). The only difference is in the configuration of environment variables. If you use JRE you should set JRE_HOME, if JDK - JAVA_HOME. Read RUNNING.txt for more details.

PS Web容器可能需要JDK才能支持JSP，因为需要Java Compiler来编译从* .jsp文件生成的Servlet。 Tomcat具有Eclipse Java Compiler包，因此它可以在JRE上运行并且仍然支持JSP。

P.S. Web containers may require JDK in order to support JSP, because Java Compiler is required to compile Servlets which are generated from *.jsp files. Tomcat has Eclipse Java Compiler bundle so it can run on JRE and still support JSP.
