Problem at starting Apache Tomcat 8.0.15 for first time

[krishnan Ayyalasomayajula]

Hi all

I've downloaded Apache Tomcat 8.0.15 and trying to start my webserver, but could not able to do. Actually I've downloaded zip file from Apache foundation. In previous versions I could start Tomcat.exe by just double clicking it and could see the status of web server. But, while if now trying to do so, nothing opening but just command prompt is opens and close automatically within a second. I've also set path. Friends... please suggest me how to overcome this in detail....THANKS IN ADVANCE

Krishnan, welcome to CodeRanch!

Have you tried starting it from the command line using the startup.bat file?

[krishnan Ayyalasomayajula]

Hi Jaikiran...

Thanks for response..

I've just set path in command line up to startup.bat. If I'm not correct, please guide me how to do it...

[Ulf Dittmer]

What Jaikiran implied was: you should try starting it from the command line, because that gives you a chance to see any error messages (which now disappear too quickly to be seen).

[Tim Holloway]

Tomcat sends (by default) certain output to stdout, including log messages targeting catalina.out.

In Windows, if a program attempts to write to stdout and there's no "DOS" window to write it to, the normal process would be to create and open one. However, that window will close when the program terminates.

In some cases, this will happen even though you launched Tomcat from a completely different (and "permanent") command-line window, owing to how things are spawned.

You can suppress this behavior. It's an option of the Windows function (I think it's on the START command).

Hi All,

Thanks For Your Responses...

When I entered command to start startup.bat I'm getting an error as follow...

"The CATALINA_HOME Environment variable is not defined correctly."

Actually, I've defined CATALINA_HOME in System variables (By navigated through MyComputer->properties->AdvanceVariables->SystemVariables->New->

Variable Name :CATALINA_HOME

Value : E:\Books\Java\apache-tomcat-8.0.15;

where tomcat-8.0.15 is my tomcat root directory

For Your convinience, I'm attaching screen shot of my error... please check it.

What's the semicolon doing there? Remove that.

[krishnan Ayyalasomayajula]

Dear Dittmer,

Still getting error even after removing semicolon.

[Tim Holloway]

At the command prompt, type:

echo %CATALINA_HOME%

What do you see?

[krishnan Ayyalasomayajula]

Dear Tim,

I've tried echo... and got the location of Tomcat roor directory. You can find it in screen shot...

[VijayAnand Venkateswaran]

Your snapshot shows JRE_HOME is not defined.Make sure you define the same in your environment variables.

[krishnan Ayyalasomayajula]

Dear Vijayanand,

I hope I've properly defined JRE_HOME. Please check the below screen shot

[VijayAnand Venkateswaran]

Hi Krishna,

refer to the snapshot attached for your reference.Also when ever you execute startup.bat you should not see any error messages.Even though your snapshot shows the jre path, startup.bat is not able to find the
jre path, i the prevous snapshot,check if any where the environment variables are being overridden.

[Ulf Dittmer]

So which URL are you trying to access, and what happens when you do that? Are there any entries in any of the log files afterwards?

Hi All..

I'm now happy to say that My Tomcat is running successfully....

I had to format my system and after installing OS, I've tried to installed Apache Tomcat. This time, no error came and everything was successfully completed.

I don't know why it's not happened previously

Anyhow, I'm really thankful to all of you for came front whenever I've asked doubts.
