Re: Java/JSP/Servlet Programmer
If I were going to just post data to a servlet I would probably skip the JSP part :) Maybe have the Servlet forward to a JSP for output. I would probably have a hard time with the lack of documentation. I have a very strong grasp of how things relate and work together but I'm not a rote memorization guy, so stuff like code completion in IDEs helps jog my memory on method names and the like. IMHO, I think conversations about design or concepts can elicit a much better picture of what a candidate does or does not know. Of course, it can be harder to quantify candidates with this method.

Question about Tomcat Documentation
Hi, I'm moving a server from 4.0.6 to 4.1.27 and I noticed something strange about the included 4.1.27 documentation. In the JNDI Resource HOWTO, the section on JDBC resources doesn't explicitly add a factory parameter, and it also says this about DBCP support: NOTE - The default data source support in Tomcat is based on the DBCP connection pool from the Jakarta Commons subproject. However, it is possible to use any other connection pool that implements javax.sql.DataSource, by writing your own custom resource factory, as described below. I was thinking that maybe now there's a default factory that can handle things, but now when I run the App I get an exception: Cannot load JDBC driver class 'null' Which makes me think the default factory is not correct. So is the documentation wrong, or are there cases where it can work with the default factory?

Re: WAR That Runs Fine Under Tomcat 4.1.24 Fails Under 4.0.6 - InvalidDataSource
Funny, I had the opposite problem (worked under 4.0.6, died horribly under 4.1.24). Can you send a stack trace? I can't remember off the top of my head, but I think there's a way to inspect the JNDI tree under Tomcat. Derek Michael Duffy wrote: I've written a Web app that works fine under Tomcat 4.1.24. It uses an app-specific Context to set up a JNDI data source that works fine. It uses the org.apache.commons.dbcp.BasicDataSourceFactory and the Oracle 9.2 JDBC type IV thin driver. The Oracle JDBC driver JAR is in TOMCAT_HOME/common/lib; all other JARs are in the WEB-INF/lib directory inside the deployed WAR. A vendor has shipped s'ware to me that has been tested under Tomcat 4.0.6. The vendor won't guarantee proper operation under 4.1.24, because it hasn't been tested there. I downloaded 4.0.6, installed it on my machine, put my app WAR in TOMCAT_HOME/webapps, and put the Context into the server.xml. The Oracle JDBC JARs are in TOMCAT_HOME/common/lib. I checked the resources page to make sure that my Context from 4.1.24 was okay for 4.0.6. There were no errors in the log file when I started up the app. The XML parser accepted the server.xml without a problem. I got the app log file that I asked for, and I can see debug info from my front controller servlet being written to it. However, as soon as it tries to access the database I get a DataSource invalid - no suitable driver error. Everything that I gave to 4.0.6 works perfectly under 4.1.24. What common error causes this? I scanned the Archive link from the mailing list page, but nothing suitable appeared. Thanks - MOD __ Do you Yahoo!? Yahoo!

Re: Creating a custom realm [I don't know how]
Realms are loaded by the container (Tomcat), so I think you need to put them in your server/lib or server/classes directories. Derek Hung Tang wrote: Hi there, How do I create my own custom realm and plug it into Tomcat for my web application? I created CustomRealm that implements Realm. But when I added a realm element in my context.xml and loaded up my application, it complained that CustomRealm could not be found (ClassNotFoundException). My CustomRealm class is in my app/WEB-INF/classes directory so I'm sure (as far as my application is concerned) that the class is in the proper classpath. I also placed the file in tomcat.home/common/lib but the error still persists. Any help would be appreciated. By the way, I'm using Tomcat 4.1.24 __ Do you Yahoo!? Yahoo!
