Hi All,

I am new to Tomcat so I would really appreciate if somebody could
help me in this.

I have Tomcat 4.1.29 installed on my windows 2000 machine. At the same
level as examples is in Tomcat path, I've created a directory called
boots(this is my application directory.) and have a index.jsp under boots
and a class called PVDatabase.class under C:\Program Files\Apache
Group\Tomcat 4.1\webapps\boots\WEB-INF\classes directory where C:\Program
Files\Apache Group\Tomcat 4.1 is my CATALINA_HOME variable.

I have modified server.xml to include the context boots there. When I
try to call this class from my index.jsp it gives me the following error.

org.apache.jasper.JasperException

Source code of org.apache.jasper.JasperException
