Tomcat啟動時一閃而過，但是jdk環境變數配置正確，並使用java或者javac命令多可以運行，但是tomcat不能運行解決辦法。

今天在使用tomcat6.0.7時出現Tomcat啟動時一閃而過，但是jdk環境變數配置正確，並使用java或者javac命令多可以運行，但是tomcat不能運行解決辦法。

1.在命令列中直接啟動tomcat時查看錯誤資訊 如; 


C:\Users\Administrator>
C:\Users\Administrator>cd D:\apache-tomcat-6.0.37\bin

C:\Users\Administrator>d:

D:\apache-tomcat-6.0.37\bin>startup.bat
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
D:\apache-tomcat-6.0.37\bin>
D:\apache-tomcat-6.0.37\bin>


2.根據以上資訊，配置java_home路徑：如java_home="D:\Program Files\java\jdk1.6.0_21\bin"
配置jre路徑： jre_home="D:\Program Files\java\jdk1.6.0_21\jre"

3.重新啟動tomcat。

4.如果以上配置完成還是不能啟動，請看下面配置. 5.由於tomcat的startup.bat啟動時，調用的是catalina.bat ,而catalina.bat調用了setclasspath.bat
在setclasspath.bat中配置的就是tomcat運行時所需的jar包及使用所需的類。
在setclasspath.bat的頭部配置JAVA_HOME和JRE_HOME的值。如下：


set JAVA_HOME=D:\Program Files\java\jdk1.6.0_21
set JRE_HOME=D:\Program Files\java\jdk1.6.0_21\jre


6.配置完成再次啟動tomcat即可。




setclasspath.bat檔案如下：
