已經(jīng)安裝了JDK1.5并設(shè)置好了JAVA_HOME,可偏偏Tomcat在啟動過程中找不到下面為大家介紹下點擊startup.bat啟動tomcat服務(wù)的實現(xiàn)思路

在XP上明明已經(jīng)安裝了JDK1.5并設(shè)置好了JAVA_HOME,可偏偏Tomcat在啟動過程中找不到。

報錯信息如下：Neither the JAVA_HOME nor the JRE_HOME environment variable is defined At least one of these environment variable is needed to run this program;提示找不到j(luò)ava_home各jre_home路徑，何解?

原因不知道了，下面來看解決辦法：

1、分析startup.bat啟動腳本：發(fā)現(xiàn)其調(diào)用了catalina.bat,而catalina.bat調(diào)用了setclasspath.bat

2、在setclasspath.bat的頭部定義了JAVA_HOME和JRE_HOME的值，那么在這里手動設(shè)置JAVA_HOME變量

復(fù)制代碼代碼如下:

 
rem 

rem Set CLASSPATH and Java options 

rem 

rem $Id: setclasspath.bat 505241 2007-02-09 10:22:58Z jfclere $ 

rem 

set JAVA_HOME=C:\Program Files\Java\jdk1.5.0_05 

set JRE_HOME=C:\Program Files\Java\jre1.5.0_05 

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 

:gotJreHome 

if not exist "%JRE_HOME%\bin\java.exe" goto noJavaHome 

if not exist "%JRE_HOME%\bin\javaw.exe" goto noJavaHome 

if not ""%1"" == ""debug"" goto okJavaHome 

echo JAVA_HOME should point to a JDK in order to run in debug mode. 

goto exit 

:gotJdkHome 

if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome 

if not exist "%JAVA_HOME%\bin\javaw.exe" goto noJavaHome 

if not exist "%JAVA_HOME%\bin\jdb.exe" goto noJavaHome 

if not exist "%JAVA_HOME%\bin\javac.exe" goto noJavaHome 

if not "%JRE_HOME%" == "" goto okJavaHome 

set JRE_HOME=%JAVA_HOME% 

goto okJavaHome 

:noJavaHome 

echo The JAVA_HOME environment variable is not defined correctly 

echo This environment variable is needed to run this program 

echo NB: JAVA_HOME should point to a JDK not a JRE 

goto exit 

:okJavaHome 

if not "?SEDIR%" == "" goto gotBasedir 

echo The BASEDIR environment variable is not defined 

echo This environment variable is needed to run this program 

goto exit 

:gotBasedir 

if exist "?SEDIR%\bin\setclasspath.bat" goto okBasedir 

echo The BASEDIR environment variable is not defined correctly 

echo This environment variable is needed to run this program 

goto exit 

:okBasedir 

rem Set the default -Djava.endorsed.dirs argument 

set JAVA_ENDORSED_DIRS=?SEDIR%\endorsed 

rem Set standard CLASSPATH 

rem Note that there are no quotes as we do not want to introduce random 

rem quotes into the CLASSPATH 

if not exist "%JAVA_HOME%\bin\tools.jar" goto noJavac 

set CLASSPATH=%JAVA_HOME%\lib\tools.jar 

:noJavac 

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="%JRE_HOME%\bin\java" 

set _RUNJAVAW="%JRE_HOME%\bin\javaw" 

set _RUNJDB="%JAVA_HOME%\bin\jdb" 

set _RUNJAVAC="%JAVA_HOME%\bin\javac" 

goto end 

:exit 

exit /b 1 

:end
