在windows中设置Eclipse、tomcat的jdk路径

当我们遇到不能在环境变量中设置JAVA_HOME的时候，比如安装cognos，它需要使用ibm自带的jdk。

这个时候就需要在Eclipse、tomcat中单独来设置jdk的路径。

1、Eclipse设置jdk路径：

打开eclipse.ini文件，在

-product

org.eclipse.epp.package.jee.product

后增加：

-vm

C:\Program Files (x86)\Java\jdk1.7.0_51\bin\javaw.exe

2、在tomcat下面设置jdk路径：

①打开catalina.bat文件，在

rem Guess CATALINA_HOME if not defined

set "CURRENT_DIR=%cd%"

if not "%CATALINA_HOME%" == "" goto gotHome

set "CATALINA_HOME=%CURRENT_DIR%"

if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome

cd ..

set "CATALINA_HOME=%cd%"

cd "%CURRENT_DIR%"

:gotHome

中增加set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_51

变为：

rem Guess CATALINA_HOME if not defined

set "CURRENT_DIR=%cd%"

set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_51

if not "%CATALINA_HOME%" == "" goto gotHome

set "CATALINA_HOME=%CURRENT_DIR%"

if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome

cd ..

set "CATALINA_HOME=%cd%"

cd "%CURRENT_DIR%"

:gotHome

②打开setclasspath.bat文件，在

rem Make sure prerequisite environment variables are set

if not "%JAVA_HOME%" == "" goto gotJdkHome

if not "%JRE_HOME%" == "" goto gotJreHome

echo Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

echo At least one of these environment variable is needed to run this program

goto exit

中增加set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_51

变为：

rem Make sure prerequisite environment variables are set

set JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0_51

if not "%JAVA_HOME%" == "" goto gotJdkHome

if not "%JRE_HOME%" == "" goto gotJreHome

echo Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

echo At least one of these environment variable is needed to run this program

goto exit

linux下面操作类似。
