Application server slimming and tweaks

Tomcat

All web applications can be removed from the webapps folder.

A basic ROOT webapp must be created as Tomcat will not work without it.

JBoss 4.2

Useless components

These services may be removed from <jboss root>/server/default/deploy to improve JBoss performances :

bsh-deployer.xml
cache-invalidation-service.xml
ejb3.deployer
ejb3-interceptors-aop.xml
http-invoker.sar
jboss-aop-jdk50.deployer
jboss-ha-local-jdbc.rar
jboss-ha-xa-jdbc.rar
jboss-xa-jdbc.rar
jbossws.sar
jms
jmx-console.war
management
monitoring-service.xml
properties-service.xml
quartz-ra.rar
schedule-manager-service.xml
scheduler-service.xml
uuid-key-generator.sar

You can also inhibitate JMSService and RMI_IIOPService in <jboss root>/server/default/conf/jboss-service.xml

JSP compilation

To allow correct compilation of JSP, you must check if:

<init-param>
	<param-name>compilerSourceVM</param-name>
	<param-value>1.5</param-value>
</init-param>

Is present in the <jboss root>/server/<server>/deploy/jboss-web.deployer/conf/web.xml
