Error:NB:JAVA_HOME should point to a jdk, not a JRE when installing Idel JDK

The workaround is To:

First check the Environment:

Run in cmd

Input Javac and Java command OK

Enter the If not exist "%java_home%\bin\java.exe" echo "%java_home%\bin\java.exe" return result: "C:\Program files\java\bin\java.exe" There is no semicolon, indicating that the environment is configured correctly that should be the problem of tomcat, on the internet to find several ways: one: in the Catalina.bat
Add a row after set current_dir=%cd%
Set Java_home=c:\program files\java\jdk1.6.0_13 (varies from person to Person)
Write your current JDK directory to death and run successfully, so you can save Tomcat from looking for it. This method is actually very savage, but it is better than no way. Questions about Tomcat not booting (nb:java_home should point to a JDK not a JRE)

There was a problem with the TOMCAT6 boot on the virtual machine today: the command window flashes and Disappears.

Run startup.bat inside cmd to get

The JAVA_HOME environment variable is not defined correctly

This environment variable are needed to run

Nb:java_home should point to a JDK not a JRE

Meaning that java_home should point to the jdk, not the Jre.

Three: the way to solve my problem:

Edit the Startup.bat file in @echo off
if "%os%" = = "windows_nt" setlocal after adding a sentence:
Java-jar-duser.dir= "d:tomcat_6.0.14" "d:tomcat_6.0.14\bin\bootstrap.jar" Start
save, run startup.bat, Get it Done. This method seems to be the most violent method ...  Specify your tomcat path directly and start the service directly ... Test success

Other strange questions about Tomcat start-up (online Search):

A.tomcat cannot start from start, but can be started in Startup.bat

JDK version too low

B. When you start, the prompt interface for loading information disappears for a few seconds on the screen, and the Tomcat application automatically shuts down

At the end of the server.xml,/host, what should be written: content

There are some displays when the C.tomcat is started, but it is still automatically turned off and cannot be started.

It may be that the address is occupied, run the "close tomcat" shortcut on the desktop, and then start Tomcat after the execution is Complete. The d.tomcat starts flashing and cannot be started.

It is possible that the port is occupied and you can find the Server.xml file under the Tomcat installation directory, such as: \eam2003\conf\server. XML, Open this file in notepad, look for 8080, and if found, change 8080 to 8088.

E.tomcat can start normally, visible to the login interface, but not logged into the system

May be a setup problem with ie, to restore all settings to the default settings, turn off the "internet assistant" or other IE plug-in "blocking pop-up windows" Function.

At last:

Interpreting Startup.bat Files

@echo Off//dos When you run a batch, each command in the batch is executed sequentially, and it is displayed on the monitor, and you can add an "echo off" if you do not want them to appear. of course, "echo off" is also a command, which itself will also show, if not even this bar is displayed, just add "@" in Front.

if "%os%" = = "windows_nt" Setlocal//determine If the current system is a window system
