configure Tomcat/5.5.9 By ' set JAVA_OPTS=-Xmx256M '

[NanFei Wang]

Hi,
In Tomcat 5.0, we can configure by ' set JAVA_OPTS=-Xmx256M ' at the file of 
startup.bat.

However, for Tomcat/5.5.9, It start by Service automatically without a file of 
startup.bat.
How and where to configure Tomcat/5.5.9 as by ' set JAVA_OPTS=-Xmx256M ' 

Regards
