Re: need help using bean (solution)
hi,
Just found the problem. Although I specified a context for my
/usr/local/apache/htdocs directory as the "/" context, I didn't specify
a context for my individual webapps. I thought they would be covered by
the "/" context. Anyway, I specified a "/networkdb" context and that
fixed the problem.
I'm not sure if that makes sense but that was the change that seemed to
have fixed the problem.
Thanks to all who replied,
PS. I can't use any sql from java.sql even if I import java.sql.* in my
JSP files. This is not a big problem since I can ( and should ) put all
the sql in separate beans anyway, but I'm wondering whether this was
indicative of a misconfiguration somewhere.

Re: need help using bean
Hi,
Firstly, thanks for the responses Bill and Karan.
I created my own application under my apache document directory ( I'm
using mod_jk ). Is this going to cause a problem? My apache root is
/usr/local/apache/htdocs and hence I placed my application in
/usr/local/apache/htdocs/networkdb and my web-inf directory is
/usr/local/apache/htdocs/networkdb/WEB-INF/ . I read that beans need to
have they class hierarchy mimic on the file system, so I placed my final
bean source file in
/usr/local/apache/htdocs/networkdb/WEB-INF/classes/edu/fit/eng/networkdb/
. JSP pages load and run fine, so I guess my mod_jk setup is working,
but beans do not load.
Must I modify my class path? Is there anything I should be doing
differently since I'm using mod_jk ( ie., since my application is not
under the $TOMCAT_HOME directory )
My simple program now looks like program now looks like
<%@ page language="java" import="edu.fit.eng.networkdb.*" %>
[...]
and my bean file (
WEB-INF/classes/edu/fit/eng/networkdb/sqlConnBean.java )...
package edu.fit.eng.networkdb;
import java.io.*;
import java.sql.*;
import java.beans.*;
public class sqlConnBean
{
private Connection conn;
[...]
Any ideas?,

Re: need help using bean
Please tell me if you have made your own web application or using the default and have you put your directories(packages) in the classes directory of the web-inf directory i.e. your package should be placed here tomcat_home\webapps\web-inf\classes or if you make your own webapplication e.g. kervin then tomcat_home\webapps\kervin\web-inf\classes hope this will help you karan - Original Message - From: "Kervin Pierre" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, January 14, 2001 1:09 AM Subject: Re: need help using bean > William Brogden wrote: > > > > Kervin Pierre wrote: > > > > > > Hello, > > > > > > I can't seem to get this to work.
