JSP's won't compile when it's stored in alternate docroot and custom servlet is used to forward requests to the jsp servlet.
Very easily reproducable problem:
sun-web.xml
...
<property name="alternatedocroot_2" value="from=/jsptestalternatedir/* dir=jsptestalternateroot"/>
...
web.xml
...
<servlet>
<servlet-name>JspTest</servlet-name>
<servlet-class>info.calavera.web.JspTest</servlet-class>
</servlet>
<servlet>
<servlet-name>JspServlet</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>JspTest</servlet-name>
<url-pattern>/jsptestalternatedir/test.jsp</url-pattern>
</servlet-mapping>
...
JspTest.java
...
getServletContext().getNamedDispatcher("JspServlet").forward(req, resp);
...
Accsessing /jsptestalternatedir/test.jsp will give you 500 and error logs says:
