Getting JSP files compiling in Railo

As part of the code samples we are writing for the Teamwork Project Manager API, I needed to get JSP pages compiling. As I have switched mainly to Railo for all my ColdFusion development, I wanted to use that servlet engine and resin to test my work

My knowledge of Resin is pretty poor so this took me a while to figure out (especially the Class Path to JDK bit) but it may help someone else in the same position.

1. Open up c:\railo\conf\resin.conf
2. Add in the following to <class-loader> -> <tree-loader path="C:/Program Files/Java/jdk1.6.0_18/lib/"/>
3. Open up c:\railo\conf\app-default.xml
4. Uncomment out:

   • <servlet-mapping url-pattern="*.jsp" servlet-name="resin-jsp"/>
     <servlet-mapping url-pattern="*.jspx" servlet-name="resin-jspx"/>
     <servlet-mapping url-pattern="*.php" servlet-name="resin-php"/>

5. Uncomment out:

   •   <servlet servlet-name="resin-jsp" servlet-class="com.caucho.jsp.JspServlet">
         <init>
           <load-tld-on-init>false</load-tld-on-init>
           <page-cache-max>1024</page-cache-max>
         </init>
         <load-on-startup/>
       </servlet>

       <servlet servlet-name="resin-jspx"
                servlet-class="com.caucho.jsp.JspServlet">
         <init>
           <load-tld-on-init>false</load-tld-on-init>   
           <page-cache-max>1024</page-cache-max>
           <xml>true</xml>
         </init>
         <load-on-startup/>
       </servlet>

       <servlet servlet-name="resin-php"
                servlet-class="com.caucho.quercus.servlet.QuercusServlet">
       </servlet>

       <servlet servlet-name="resin-xtp" servlet-class="com.caucho.jsp.XtpServlet"/>

6. Wait for Railo to restart or Restart it in Services.

Bingo. JSP pages will now be processed along with CFM files
