At least tell us what are you trying to do in
/servlet/qry_training.java at line 106 and
some lines before.

P.S.: It's a common convention to use classnames
with upper case first letter. (Like QryTraining)

jsp bean error to find class

[yaya]

Hi,
I tried to connect to mysql database with bean but fail with following error
:
org.apache.jasper.JasperException: Unable to compile class for
JSP/usr/local/jakarta-tomcat-3.2.1/work/localhost_8080/_0002fjsp_0002fdataba

Beans.instantiate(this.getClass().getClassLoader(), "DataBaseSelect");

I already put DataBaseSelect.java  DataBaseSelect in
/usr/local/jakarta-tomcat-3.2.1/webapps/examples/WEB-INF/classes

Looks like it fail to find the class,..so where should I put the class file
?

This is the jsp files ( in
/usr/local/jakarta-tomcat-3.2.1/webapps/examples/jsp)
html
head
titleSelect everything from a database/title
/head
body

jsp:useBean id='select' class='DataBaseSelect' scope='page'
type="DatabaseSelect" /

% out.print(select.connect()); %
br
% out.print(select.select()); %

pFormat results

br
%@ page import="java.util.Vector" %
% Vector aResult = select.getResult(); %

table
% for (int i=0; i  aResult.size(); i++) { %
   tr
   td
   % out.print(aResult.elementAt(i)); %
   /td
   /tr
% } %
/table

/body
/html

Thanks
