Re: question about WEB-INF/lib
Oh, I'm so embarrased! I should have actually LOOKED at our tomcat.bat/sh files. We had created a 'realm' for our own custom authentication. The new classes are in the same packages as our webapp classes, so someone added our webapp/WEB-INF/classes directory to the classpath for tomcat. Very bad! Our classes were being loaded by the parent classloader and when we tried to access a 3rd party class within the webapp's lib it couldn't be found. I moved these classes into a separate jar, put that jar in tomcat/lib, removed the classpath modification, and everything works great. As a suggestion to Joe, you may want to put some trace messages in your classes and print out the class loaders. Another thing I did was install a clean version of tomcat and create a very simple webapp with some jsp that calls a bean that calls a 3rd party class. I also made sure there was nothing in my CLASSPATH. This just verified that it was my problem and not Tomcat's. Thanks for the help. I learned a lot on this thread of discussion. Sorry it was at the expense of others. :o) Dave "Craig R.

The most critical issue (and the one that will definitely cause ClassNotFoundException errors) is to have a copy of one of the same application classes (or the JDBC driver classes in your case) *also* visible through the CLASSPATH (since you're using Tomcat 3.2 this matters), in $TOMCAT_HOME/lib, or in your Java extensions directory ($JAVA_HOME/jre/lib/ext). The reason this causes you grief is that, because of the way Java class loading works in Tomcat 3.2, the "shared" version of the class will be loaded. And, this "shared" copy (because it was loaded from a classloader that is the parent of the webapp class loader) cannot itself load classes from the webapp classloader (in class loading terms, delegation can go *up* the classloader hierarchy but not *down*). If this is not the cause of the problem, the only way to resolve it is to create a minimal webapp that illustrates the problem, and post it along with a bug report.

Re: question about WEB-INF/lib
I'm pretty certain that my war file is set up correctly. In my WEB-INF/lib directoy I have jdbc jar file that tomcat can't find and the tomcat user manual for deploying tomcat applications says WEB-INF/lib/ - This directory contains JAR files that contain Java class files (and associated resources) required for your application, such as third party class libraries or JDBC drivers. My servlets are in the WEB-INF/classes directory and the same document says WEB-INF/classes/ - This directory contains any Java class files (and associated resources) required for your application, including both servlet and non-servlet classes, that are not combined into JAR files. Aside from that I have read the Servlet 2.3 spec on this topic and it says this about the WEB-INF/lib The /WEB-INF/lib/*.jar area for Java ARchive files. These files contain servlets, beans, and other utility classes useful to the web application. The web application class loader can load class from any of these archive files. Here is what it says about the WEB-INF/classes directory The /WEB-INF/classes/* directory for servlet and utility classes. The classes in this directory are available to the application class loader. Now to re-cap I have a jdbc jar file in WEB-INF/lib and I'm trying to access it from a servlet in WEB-INF/classes After looking at the spec again it says the container "can load classes from any of these archive files". I suppose this could mean that it is optional for the container to load the classes found in this directory, in which case tomcat is adhearing to the spec and it is not required to load all the classes it finds there. If you see something that I'm mis-interpting please let me know. thanks joe On 25 Jul 2001 11:39:11 -0700, Craig R.

RE: question about WEB-INF/lib
The jar file I have is a ".jar" file however it is a compressed jar file - does this matter? I seem to remember something about having to explictily add compressed jar files to a classpath where as the jvm would find all the uncompressed jar files in a directory if you just passed it the directory name.

What's the name of the JDBC file? If it ends in .zip try renaming it to .jar. See, for example, http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg27920.html -- Andrew
Re: question about WEB-INF/lib
I see this problem, too. I'm using Tomcat 3.2.x. It appears to me to be a bug. I've seen others with this problem on this mailing list. Can anyone verify that this actually does work? (Just trying to add some weight to your claim and get it fixed if it is a bug. :o) Thanks, Dave Joseph D Toussaint <[EMAIL PROTECTED]> on 07/24/2001 11:55:44 AM Please respond to [EMAIL PROTECTED] To: [EMAIL PROTECTED] cc: Subject: question about WEB-INF/lib It's my understanding that any jar files in the WEB-INF/lib directory should be found by the container when the app is deployed - however I havea jdbc driver in that directory and I'm getting a class not found exception.

question about WEB-INF/lib
It's my understanding that any jar files in the WEB-INF/lib directory should be found by the container when the app is deployed - however I havea jdbc driver in that directory and I'm getting a class not found exception. When ever I have set up tomcat before I've always edited the tomcat.sh script so search all the WEB-INF/lib directories for every web application - however this time I'd like to do it right.
