I am a new user of tomcat. I have seen in the documentation that JAVA_HOME variable has to be setup to the jdk folder. at the c prompt,I am using set JAVA_HOME = c:\java\jdk1.3.1_01 after doing this ,when i try to start tomcat,It gives me the error: You must set JAVA_HOME to point at your Java Development Kit installation
Please help me in setting up tomcat so that i can run my servlets. Thanks, raj

You need to set JAVA_HOME for your entire system, not just the one MSDOS prompt window since Tomcat starts another window. If you are using Tomcat 3 you need to set TOMCAT_HOME also, if Tomcat 4 it needs CATALINA_HOME. (They did it that way so you could have both 3 and 4 on the same system.) Bill
add to autoexec.bat set JAVA_HOME = c:\java\jdk1.3.1_01

You can also set environment variables in Windows by right-clicking on "My Computer", and in one of the tabs (Depending on which version of windows you run) there is an "Environment variables" section where you can see and edit all your environment variables.

hi guys, thank you very much.. I am able to make tomcat start now. but the tomcat is not starting from the command prompt. I am able to run it only from the bin folder and invoking the startup file. I entered the variables JAVA_HOME and CATALINA_HOME from settings--->control panel-->System---->Advanced--->Environmental variables. Even though I can work like this,Just for curiosity,why am i not able to invoke tomcat from command prompt? Please if you know it,let me know. Thanks, raj

The reason that you can not run this from the command prompt is because you are typing set JAVA_HOME = c:\java\jdk1.3.1_01 Note the extra space after the JAVA_HOME. this does not create a variable called JAVA_HOME, instead it creates a variable called JAVA_HOME<space> where <space> is one character of whitespace. Try typing set JAVA_HOME=c:\java\jdk1.3.1_01 Now run Tomcat, it will work fine.
