[jboss-user] [Tomcat, HTTPD, Servlets & JSP] - ERROR [org.apache.catalina.core.ContainerBase.[jboss.web]...

Hi!

I am using jboss-4.0.5.GA and I have an application that it works correctly. 
However, after some days when I try to access my home page, this gets stucked.

And looking for a log I see the following error:

2007-06-24 23:38:33,714 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/simadpro].[jsp]] Servlet.service() for servlet jsp threw exception

Finally, when I start JBoss, everything seems fine. But, does anyone have any idea as to how to resolve this?. I tried searching about this problem but have not found anything. 

Thank you very much for your help.
