Turn: The Java_home jre_home solution was not found during Tomcat boot

Transferred from: http://blog.sina.com.cn/s/blog_61c006ea0100l1u6.html

Original:

On XP is clearly installed JDK1.5 and set up the Java_home, but Tomcat in the boot process can not find.

The error message is as follows: Neither the Java_home nor the JRE_HOME environment variable is defined at least one of these environment variable I s needed to run the program; hint java_home each jre_home path cannot be found, what solution?

The reason is not known, the following look at the solution:

1, Analysis Startup.bat startup script: found that it called the Catalina.bat, and Catalina.bat called the Setclasspath.bat

2, in Setclasspath.bat's head defines the value of Java_home and Jre_home, then manually set the Java_home variable here

3. Restart Tomcat, typing http://localhost:8080 verification, problem solving.

TOMCAT5 need jdk1.6 to do support, jdk1.5 not enough.

of my own

My system environment is as follows

The difference is that when I install, Java has been upgraded to Jdk1.8.0_65,tomact using: apache-tomcat-8.0.28, the operating system uses the win 10 64-bit

I also set up the configuration of the environment variables (including Java_home JAVA_JRE and Path,classpath all the possible configurations I've been looking for online)

Run Java javac under CMD, startup.bat when running Tomcat jre_home environment variable was defined at least one of these environment Variable is needed to run

Helpless online A check, found this article, set up a good

Set Java_home=c:\program files\java\jdk1.8.0_65

Set Jre_home=c:\program Files\java\jdk1.8.0_65\jre

Run Startup.bat again:)
