使Tomcat指向指定的JDK目录

一。

1，修改bin文件夹下面的catalina.bat文件，把如下内容

   rem ----- Execute The Requested Command ---------------------------------------

echo Using CATALINA_BASE:   %CATALINA_BASE%
echo Using CATALINA_HOME:   %CATALINA_HOME%
echo Using CATALINA_TMPDIR: %CATALINA_TMPDIR%
echo Using JAVA_HOME:      %JAVA_HOME%

修改为：

echo Using CATALINA_BASE:   %CATALINA_BASE%
echo Using CATALINA_HOME:   %CATALINA_HOME%
echo Using CATALINA_TMPDIR: %CATALINA_TMPDIR%
echo Using JAVA_HOME:     D:/jdk                                       -------这里的d:/jdk即为需要指定的目录---------

 

2，修改bin文件夹下面的setclasspath.bat文件，把如下内容：

 
rem Set standard command for invoking Java.
rem Note that NT requires a window name argument when using start.
rem Also note the quoting as JAVA_HOME may contain spaces.
set _RUNJAVA="%JAVA_HOME%/bin/java"
set _RUNJAVAW="%JAVA_HOME%/bin/javaw"
set _RUNJDB="%JAVA_HOME%/bin/jdb"
set _RUNJAVAC="%JAVA_HOME%/bin/javac"

修改为:

rem Set standard command for invoking Java.
rem Note that NT requires a window name argument when using start.
rem Also note the quoting as JAVA_HOME may contain spaces.
set _RUNJAVA="D:/jdk5/bin/java"
set _RUNJAVAW="D:/jdk5/bin/javaw"
set _RUNJDB="D:/jdk5/bin/jdb"

set _RUNJAVAC="D:/jdk5/bin/javac"

二。

1.下载JDK6*.ZIP 然后解压，如：d:\java   (下面有jdk  和jre目录）
2.去环境变量里加一个系统变量  JAVA6_HOME  指向  d:\java\jdk

3，修改bin文件夹下面的catalina.bat文件，把如下内容
把  %JAVA_HOME%  替换为  %JAVA6_HOME% 即可
