DOS Memory Setting

If you start Tomcat or the JSWDK server from Windows 95 or 98, you proba 

bly have to modify the amount of memory DOS allocates for environment

variables. To do this, start a fresh DOS window, click on the MS DOS icon in

the top left corner of the window, and select 

Properties

. From there,

choose the 

Memory

 tab, go to the 

Initial Environment

 setting, and change

the value from 

Auto

 to 2816. This configuration only needs to be done once.

Tomcat 3.0 CR/LF Settings

The first releases of Tomcat suffered from a serious problem: the text files

were saved in Unix format (where the end of line is marked with a linefeed),

not Windows format (where the end of the line is marked with a carriage

return/linefeed pair). As a result, the startup and shutdown scripts failed on

Windows. You can determine if your version suffers from this problem by

opening 

install_dir/startup.bat

 in Notepad; if it appears normal you

have a patched version. If the file appears to be one long jumbled line, then

quit Notepad and open and immediately save the following files using Word 

pad (not Notepad):

install_dir

/

startup.bat

install_dir

/

tomcat.bat

install_dir

/

shutdown.bat

install_dir

/

tomcatEnv.bat

install_dir

/

webpages/WEB INF/web.xml

install_dir

/

examples/WEB INF/web.xml

Start the Server

To start one of the  real  Web servers, check its documentation. In many

cases, starting it involves executing a command called 

httpd

 either from the

command line or by instructing the operating system to do so automatically

when the system is first booted. 

With Tomcat 3.0, you start the server by executing a script called 

startup

in the main installation directory. With the JSWDK 1.0.1, you execute a simi 

lar script called 

startserver

.
