Which connection pool class to use?
Hi, I am using Tomcat 4 and Postgres 7.1.3 for a custom taglibs
project. Postgres has some JDBC 2.0 support but it doesn't seem to
have connection pool support. There seem to be a ton of connection
pool classes out there. Does anyone have a recomendation? Something
easy to use for a java newbie?
Thanks

I have used the JavaExchange DbConnectionBroker class extensively, and find that it is very easy to use - especially for servlets. Check it out:

I adapted one that is described in this book:
http://developer.java.sun.com/developer/onlineTraining/Programming/JDCBook/
In chapter 8 you can find described and implemented connection pooling and
it's quite easy to understand. I use it in my bean which sits in application
scope and in fact owns one instance of JDCConnectionPool.

virtual directory set-up

Any suggestions anyone?

Subject: virtual directory set-up
Virtual directories anyone?
I am using Tomcat 4.0 as both a servlet container and a Web server. I am not
running any other web server.
Question: How do I add a virtual directory.
I presume that the default path is
"D:\jakarta\jakarta-tomcat-4.0-rc1\webapps" (on my machine)
I would also like to have "D:\Program
Files\ESRI\ArcIMS3.1\Manager\frame.htm" exposed as:
http://localhost/Manager/frame.htm (Not to be confused with the
manager directory under tomcat)
If I were using apache 1.3.19 my directions for installing a virtual
directory are to add the following to the "D:\Program Files\Apache
Group\Apache\conf\httpd.conf" file.
Alias /WEBSITE "C:/ArcIMS/WebSite"
Alias /website "C:/ArcIMS/WebSite"
Alias /WebSite "C:/ArcIMS/WebSite"
Alias /Website "C:/ArcIMS/WebSite"
Alias /MANAGER "C:/Program Files/ESRI/ArcIMS3.1/Manager"
Alias /manager "C:/Program Files/ESRI/ArcIMS3.1/Manager"
Alias /Manager "C:/Program Files/ESRI/ArcIMS3.1/Manager"
Alias /Output "C:/ArcIMS/Output"
Alias /output "C:/ArcIMS/Output"
Alias /OUTPUT "C:/ArcIMS/Output"
#Apache 1.3.14 users must add these additional lines. Be sure to update
#the Website pathname for your site.
<Directory "C:/ArcIMS/Website">
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
But again, I'm not using Apache, or IIS. I am using Tomcat 4.0 as both web
server and Servlet container.
It appears that maybe I need to add something like "<Context path=......./>"
into the conf\server.xml file but the format and attributes that I need
aren't clear for any documentation I can find.
Thanks in advance......

This person is actually running an application that sends me data and
not
using a browser.
Does this mean he's closing the connection before it finishes?

Shalom Scott Weaver ,
Connection reset by peer is caused by a user that closes his browser
window yet the servlet is trying to connect him. Do not worry about it
just happens. If you need an event try
window.open('http:/www.url.com','_blank') on unload using javascript it
will create a popup window.

I've been running Tomcat for quite awhile successfully but now I'm

this for the first time.
What causes this and how can I fix it? I read what it means in the Java

and it seems that the problem isn't with Tomcat but with the person
POSTing
me the data (is that right?)
Thanks for the help.
