+ <p>During development it may be more productive to avoid copying files
(static
+ resources, JSPs, classes, jars...) and configure tomcat to use files from
their
+ source locations. To do that, several customisations of the context
configuration are
+ required:</p>
+ <ul>
+ <li>The <code>VirtualDirContext</code> implementation of
+ <a href="resources.html">Resources</a></li>
+ <li>The <code>VirtualWebappLoader</code> implementation of
+ <a href="loader.html">Loader</a></li>
+ <li><code>scanAllDirectories="true"</code> on the <a
href="jar-scanner.html">JarScanner</a></li>
+ </ul>
+ <p>To illustrate this feature, here is an example of a standard maven
webapp source tree:</p>
+<source>
+mywebapp/
+ src/
+ main/
+ java/
+ resources/
+ webapp/
+ WEB-INF/
+ classes/
+ target/
+ classes/
+</source>
+ <p>To deploy such an application (assuming it also uses the log4j maven
artefact),
+ the context configuration looks like:</p>
+<source>
+<Context path="/mywebapp" docBase="/Users/theuser/mywebapp/src/main/webapp"
>
+ <Resources className="org.apache.naming.resources.VirtualDirContext"
+
extraResourcePaths="/WEB-INF/classes=/Users/theuser/mywebapp/target/classes" />
+ <Loader className="org.apache.catalina.loader.VirtualWebappLoader"
+
virtualClasspath="/Users/theuser/mywebapp/target/classes;/Users/theuser/.m2/repository/log4j/log4j/1.2.15/log4j-1.2.15.jar"
/>
+ <JarScanner scanAllDirectories="true" />
+</Context>
+</source>
+
+ <p>Here is another example where the webapp serves pictures under
/pictures and movies
+ under /movies and also depends on another maven project mylib that would
normally
+ produce a jar to be packaged in WEB-INF/lib:</p>
+<source>
+mylib/
+ src/
+ main/
+ java/
+ resources/
+ META-INF/
+ resources/
+ target/
+ classes/
+mymovies/
+mypictures/
+mywebapp/
+ src/
+ main/
+ java/
+ resources/
+ webapp/
+ WEB-INF/
+ classes/
+ target/
+ classes/
+</source>
+ <p>The configuration is:</p>
+<source>
+<Context path="/mywebapp" docBase="/Users/theuser/mywebapp/src/main/webapp"
>
+ <Resources className="org.apache.naming.resources.VirtualDirContext"
+
extraResourcePaths="/WEB-INF/classes=/Users/theuser/mywebapp/target/classes,/pictures=/Users/theuser/mypictures,/movies=/Users/theuser/mymovies"
/>
+ <Loader className="org.apache.catalina.loader.VirtualWebappLoader"
+
virtualClasspath="/Users/theuser/mywebapp/target/classes;/Users/theuser/mylib/target/classes;/Users/theuser/.m2/repository/log4j/log4j/1.2.15/log4j-1.2.15.jar"
/>
+ <JarScanner scanAllDirectories="true" />
+</Context>
+</source>
+ <p>Note that resources in mylib/target/classes/META-INF/resources/ are
mapped to / as
+ required by servlet 3 specifications.</p>
