Development/Java & J2EE/Tomcat/jasper-prod 1 Tomcat JSP production configuration ---- More info at {link:Tomcat JSP config |http://tomcat.apache.org/tomcat-5.5-doc/jasper-howto.html#Production%20Configuration} ---- When using Jasper 2 in a production Tomcat server you should consider making the following changes from the default configuration. * __development__:To disable on access checks for JSP pages compilation set this to false. * __genStringAsCharArray__:To generate slightly more efficient char arrays, set this to true. * __modificationTestInterval__:If development has to be set to true for any reason (such as dynamic generation of JSPs), setting this to a high value will improve performance a lot. * __trimSpaces__:To remove useless bytes from the response, set this to true. * __reloading__:Should Jasper check for modified JSPs? * __keepgenerated__:Should we keep the generated Java source code for each page instead of deleting it * __checkInterval__:If development is false and reloading is true, background compiles are enabled. checkInterval is the time in seconds between checks to see if a JSP page needs to be recompiled. Default 300 seconds. * __modificationTestInterval__:Checks for modification for a given JSP file (and all its dependent files) will be performed only once every specified amount of seconds. Setting this to 0 will cause the JSP to be checked on every access. Default is 4 seconds. This is all configured in tomcat's conf/web.xml which is applied to all web.xml files for all apps.\\ Modify in __$TOMCAT_HOME/conf/web.xml__: {code} <servlet> <servlet-name>jsp</servlet-name> <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> <init-param> <param-name>fork</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>development</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>genStringAsCharArray</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>trimSpaces</param-name> <param-value>true</param-value> </init-param> <init-param> <param-name>reloading</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>keepgenerated</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>checkInterval</param-name> <param-value>99999</param-value> </init-param> <init-param> <param-name>modificationTestInterval</param-name> <param-value>99999</param-value> </init-param> <init-param> <param-name>xpoweredBy</param-name> <param-value>false</param-value> </init-param> <load-on-startup>3</load-on-startup> </servlet> {code} 2006-08-26 14:22:51.0 2006-08-26 14:22:51.0
