When you don't want to stop the jsp generation at first jsp syntax error, use
-<code>failOnError="false"</code>and with
<code>showSuccess="true"</code>
-all successfull <i>jsp to java</i> generation are printed out. Sometimes it is

<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>
