You can enable Java 5 compiler settings for your JSP pages in Tomcat by navigating to your <tomcat 5 install dir>\conf directory and then editing the web.xml file.

From there, scroll down to around line 212 or so and you will see the following servlet definition:

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>xpoweredBy</param-name>         <param-value>false</param-value>     </init-param>     <load-on-startup>3</load-on-startup> </servlet>

You can add a new init-param with the name compilerSourceVM and value of 1.5 to turn on the Java 5 features. The new init-param would look something like this:

Code:

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

This feature in the default web.xml file that ships with Tomcat is described in the comment above this snippet of code that explains all the optional init-params you can pass to Tomcat on startup. Valid values are 1.4 and 1.5.
