Servlet.service() error on JBoss SA 6

[r.val]

Hi guys,

I'm in trouble with a web application on JBoss AS 6.

Frequently in my log file appears the following error:

ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/].[jsp]] (http-0.0.0.0-80-9) Servlet.service() for servlet jsp threw exception: java.lang.NullPointerException

Web app seems to work fine, but i would resolve this error.

I'm using JSF 2.0 and Pretty Faces.

I attached web.xml too, hoping it will be useful to anyone.

Hi,

the NPE is caused by your JSP. Every Servlet-Container generates some Java-Code from JSP's, take a look in work/jboss.web/localhost, there you should be able to find the class index_jsp, look what happens in line 53.

Best regards,
