Dual Web Apps (IIS), Dual Tomcat instances, How-to?
Hi, Tomcat: 4.1 IIS: 5.0 OS: Windows2000 I currently have a web app. configured in IIS to talk to a Tomcat instance, fine, no problem. But, now, I want to setup a development web app (instance) and a separate QA/Testing web app (instance). The ISAPI_Redirector2.dll has registry settings. In the registry, one of the entries needs to point to the location of the installed Tomcat. So, when I configure IIS with two different web apps, I would need two different installed Tomcat instances, correct? When I installed a new Tomcat (using the .exe), it configured the services to the same name as my original Tomcat instance. So, in the services window, I had a Tomcat 4.1 service. Now, I still have that same service, but it's still pointing to my original Tomcat instance. I was expecting a 2nd service for my 2nd Tomcat instance. Are there instructions for manually installing a specific service? SORRY, more than one question here: Also, when I manually started my 2nd Tomcat instance (while my 1st instance was running), I got a JVM Bind to port message. It said that port 8009 was already in use. I changed all port numbers in the server.xml (I just added one to each number). Those new ports are open on the box. Any ideas?

isapi_redirector2.dll fails - red arrow
Tomcat = 4.1 IIS = 5.0 OS = windows2000 DLL = isapi_redirector2.dll (downloaded from http://apache.mirrors.pair.com/jakarta/tomcat-connectors/jk2/binaries/win32/) I followed http://www.onjava.com/pub/a/onjava/2002/12/18/tomcat.html for instructions. I've made double sure my entries in the registry are correct. I checked read/write/execute when adding the filter to the virtual directory. I have my workers.properties, uriworkermap.properties, and I added the connector tag in the server.xml. All of these are in CATALINA_HOME/conf. Once I was done with all of this configuration, I restarted the server (warm boot, not cold boot). Now, in IIS under ISAPI Filters in the 'default web site' I have a red arrow. The status is 'Not Loaded.' Any suggestions on getting the arrow green? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Multiple webapps talking to same DB
Version of Tomcat - 4.1.24 OS - WinXP (development workstation) DB - MySQL 4.0.13 I currently have a single webapp (test1) that can connect to the database and perform DB operations just fine. This uses JSP, Servlets and JDBC. What I want to do is have other webapps connect to the same database. Here is what I did: 1. I copied my existing webapp, tomcat_home\webapps\test1 and created tomcat_home\webapps\test2. 2. I restarted tomcat and when invoking the test2 webapp, I get the following error: java.sql.SQLException: Cannot load JDBC driver class 'null' This error happens when I call the getConnection() method on the DataSource object. I believe I don't have the correct configuration in the server.xml for the webapp, test2. I tried several different ways to try and get this to work, but those have failed so far. So, when making a straight copy of one webapp like I did above, what would need to change in the server.xml (in the MySQL section) to get this to work? Or, would the culprit be some other configuration? Thanks for any help on this, Kevin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What is the maximum session handling capability
In the past, I've used Tomcat for very small projects. But, now I may be using Apache/Tomcat for an actual business-related project. I've been looking in the documentation, but haven't found this answer just yet. I'm sure this has been asked several times (I did a search in the archives, but didn't find the answer).

1. starting from tomcat-home\bin, I type in the command - startup.
2. starting from tomcat-home\bin, I type in the command - shutdown.
I do this after every change I make to the tomcat configuration.
After I issue the command 'startup,' then I see the classpath output in
that
same DOS window.
Does my server.xml and web.xml setting look correct to all?

No I did not, but now I do and I still receive the same error.
I have printed out my classpath on the tomcat startup DOS window.
This is:
setting the jdbc jar to classpath *
* classpath is:
C:\Development\j2sdk1.4.1_01\lib\tools.jar;C:\development\ja
karta-tomcat-4.1.12\common\lib\mysql-connector-java-3.0.6-stable-bin.jar;
**
Currently, I have the jdbc jar file under common\lib, server\lib and
webapps\dbtest\WEB-INF\lib, hoping Tomcat will 'see' it under one of
these
locations.
btw, I'm a first-timer for connecting Tomcat to a database.
Thanks
