 are automatically compiled as part of the build process.

+<p>
+At the jasper2 task you can use the option <code>addWebXmlMappings</code> for 
+automatic merge the <code>${webapp.path}/WEB-INF/generated_web.xml</code>
+with the current web application deployment descriptor at <code>${webapp.path}/WEB-INF/web.xml</code>.
+When you want to use Java 5 feature inside your jsp's, add the following javac compiler task
+attributes: <code>source=&quot;1.5&quot; target=&quot;1.5&quot;</code>. For live application
+you can also compile with <code>optimize=&quot;on&quot;</code> and without debug info
+<code>debug=&quot;off&quot;</code>.
+</p>
+
+<p>
+When you don't want to stop the jsp generation at first jsp syntax error, use   
+<code>failOnError=&quot;false&quot;</code>and with <code>showSuccess=&quot;true&quot;</code>
+all successfull <i>jsp to java</i> generation are printed out. Sometimes it is
+very helpfull, when you cleanup the generate java source files at <code>${webapp.path}/WEB-INF/src</code>
+and the compile jsp servlet classes at <code>${webapp.path}/WEB-INF/classes/org/apache/jsp</code>.

+
+<p><strong>Hints:</strong>
+<ul>
+<li> When you switch to another tomcat release, then regenerate and recompile
+your jsp's with this version again!</li>
+<li>Use java system property at server runtime to disable tag pooling <code>org.apache.jasper.runtime.JspFactoryImpl.USE_POOL=false</code>.
+and limit the buffering with <code>org.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true</code>. Note that changing
+from the defaults may affect performance, but depending on the application.</li>
