[OT] : How to get a connection from Tomcat DBCP from a remote application?
Hi,
I am using Tomcat 5.5.7 and configured DBCP properly to work with Oracle 9i.
Everything is working fine if I try to get the connection from the Pool from an
application deployed in Tomcat.
However if I try to get the connection from the Pool from an application which
is not deployed in Tomcat (remote client), I am getting not bound exceptions.
Here is the code:
import java.util.*;
import javax.naming.*;
import javax.sql.DataSource;
public class ClientTest
{
public static void main(String[] args)
{
Context ctx = null;
try
{
Hashtable props = new Hashtable();
props.put(Context.INITIAL_CONTEXT_FACTORY,
org.apache.naming.java.javaURLContextFactory);
props.put(Context.URL_PKG_PREFIXES, org.apache.catalina.util.naming);
ctx = new InitialContext(props);
DataSource dataSource = (DataSource)ctx.lookup(java:/comp/env/jdbc/test);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
Stacktrace shows:
javax.naming.NameNotFoundException: Name java: is not bound in this Context
at org.apache.naming.NamingContext.list(NamingContext.java:344)
at org.apache.naming.NamingContext.list(NamingContext.java:367)
at javax.naming.InitialContext.list(InitialContext.java:387)
What am I doing wrong? Is it allowed to access the Pool from remote client in
first place?
Thanks in advance,
Appa

Re: [OT] Webapp upgrades and browser caching
Hi Justin, Sorry If I don't understand your question correctly, but I hope this is what you are looking for. Just add a dummy variable at the end the url. if your css file is http://www.server.com/myapp/v1/main.css, then add ?dummy=%=new java.util.Date().getTime()% i.e., http://www.server.com/myapp/v1/main.css?dummy=%=new java.util.Date().getTime()% Appa Justin Ruthenbeck [EMAIL PROTECTED] wrote: I'm looking for some advice about how to handle the following situation. (1) Apache 2.x in front of Tomcat 5.x (2) Deploy new web application. Bunch of servlets, bunch of jsps, bunch of static content (mainly js, css). (3) Many users use the application, during which time their browsers cache lots of static content (4) We do a major version upgrade of the webapp, including (almost) all new static content, but URLs stay the same (to alleviate bookmark-maintenance requirements). The problem arises when the browsers continue to use their cached version of the static content. Now, the browsers eventually get updated, but immediately after deployment there are huge numbers of graphical and functional (js files) problems. It seems like behavior in this area is widely different amongst browsers and/or their settings. I have only come up with the following option: (1) Play with URLs. New deployments can be deployed under a different url domain like: http://www.server.com/myapp/v1/main.css http://www.server.com/myapp/v2/main.css This would force browsers to get new content since the content appears as totally new content to the browser. Aside from disabling static content caching, are there any other options out there?

Re: How to use digital certificates
HTTPS is working properly(I configured SSL properly). I installed the root/chain cert in Tomcat and User certs in browser. I set the clientauthentication to true in server.xml. It is working properly. The only thing I need is to pick the username/password from the user cert and authenticate. As said, I think I'll have to write custom Realm. Where can I get more information on getting the usernames from the certficates? Appa Bill Barker [EMAIL PROTECTED] wrote: Assuming that iPlanet is sending a normal x509 chain, then it should be mostly working. You'll have to make certain that the root-CA is installed in cacerts (I'm assuming that you are using JSSE) so that the client-cert can be verified. At least with the Sun JVM, I believe that only Verisign and Thwate are installed by default. Getting the name is a bit more of a problem. It is usually the CN of the Subject, but not always. If this is the case with your certs, then you'll need a custom Realm that extracts the CN and validates the user (MemoryRealm uses the full Subject as the user-name). appa rao wrote in message news:[EMAIL PROTECTED] Thanks for the reply.. let me clearly tell you the problem.. we use certificates generated by iPlanet Certificate Server. All the client(user) certificates are on a swipe card which are read by Gemplus card reader using USB port The problem is when the user swipes it, user should automatically be authenticated..(currently we have another web application running on iPlanet web server - which picks up username from the card and authenticates against LDAP).
