JasperException: The value for the useBean class ___ attribute is invalid

[Chris Patterson]

Hello, pls help with the following issue:

My JSP calls a Java Bean
and works OK for both versions, Tomcat 5.5 and Tomcat 7.1

My problem is when I move that same JSP to a sub-directory,
then I get the 500 error:

org.apache.jasper.JasperException: /StrBean.jsp(26,0) The value for the useBean 
class attribute
jdbcbean.StringBean is invalid.

I think it could be solved changing the server.xml configuration described 
below (?)

        <Host name="domain.com" appBase="/home/serverhome/public_html">
          <Alias>www.domain.com</Alias>
          <Context path="" reloadable="true" docBase="/home/serverhome/public_html" 
debug="1"/>
       </Host>

Any ideas about where to fix the problem ?
