Tomcat Neither the Java_home nor the JRE_HOME environment variable is defined

One can see that the JDK environment is problematic, but the JDK used so long has been well-configured, how one to Tomcat on the so sentimental.

Finally the solution, originally my JDK was downloaded directly from the official website, although I modified the java_home, but not too smart Tomcat still does not automatically identify the java_home path.

Linux Workarounds:
Edit the file/usr/local/tomcat/bin/catalina.sh (modified according to your own JDK path) at the beginning of the body of the file, that is, before the official code, about 99 lines to add the following code

1	exportJAVA_HOME=/usr/local/jdk

2	exportJRE_HOME=/usr/local/jdk/jre

After the change, it's probably like this.
