To configure Tomcat, click on “Start”

> “Apache Tomcat 6.0”
-
> “Configure
Tomcat”.







Select the “Java” tab. Set the “Initial memory po
ol” and “Maximum memory pool”
values to 1024MB. In the “Java Options” text box, add the following lines:


-
XX:MaxPermSize=192m

-
XX:PermSize=128m

-
XX:+CMSPermGenSweepingEnabled

-
XX:+CMSClassUnloadingEnabled

-
XX:+UseParallelOldGC

-
Xloggc:<tomcat_install_dir
>
\

tomcatgc.log


For the Java Classpath, add the following:

;<tomcat_install_dir>
\
webapps
\
ROOT
\
WEB
-

\
classes;<tomcat_install_dir>
\
lib

api.jar

where <tomcat_install_dir> is the destination folder chosen in Step 7.


Click “Apply”, then

click “OK” to save your changes.

At this point, it may be desirable to ensure that the Apache Tomcat software is installed
correctly. To start this process, click on “Start”
-
> “Settings”
-
> “Control Panel”
-
>
“Administrative Tools”
-
> “Services”.




In the “Services” window, stop and disable the following services (if installed): IIS Admin
Service, Simple Mail Transport Protocol (SMTP), and World Wide Web Publishing
Service.



In the “Services” window, select the Apache Tomcat service, and click on the
start
button (the button with the arrow pointing to the right near the top of the window).

On another computer, start Internet Explorer, and in the Address box type in the following URL:

“http://<server_name>/”

where <server_name> is
the name of the computer that Apache Tomcat is installed on. Once
the URL is entered, press “enter” on the keyboard. If the installation is succe
ssful, the Apache
Tomcat
home page should appear.
