Re: WEB-INF/classes not loading from corrrect classloader
Does this happen with the JPDA debugger, or running tomcat inside your IDE? [EMAIL PROTECTED] 02/28/03 16:38 PM Hello, While I'm having no problems running *outside* a debugger, I am running into a problem with classloading as I try to run 2 web-application through a debugger. The two projects have overlapping copies of the same class files (ie, both projects use Class A). The problem is that when Tomcat (4.0.6) is run through my debugger, the WEB-INF/classes are not loaded by org.apache.catalina.loader.WebappClassLoader. They are apparently loaded by the system classloader. So my Class A instance is shared between my 2 web-apps when in fact they should each have their own instance. Run outside the debugger, the WebappClassloader does its job both web-apps get their unique copies of class A. Here is what Class A has to say about who's loading it: Outside the debugger: - Class A's ClassLoader's class is [class org.apache.catalina.loader. WebappClassLoader] ClassLoader's parent class is [class org.apache.catalina.loader.StandardClassLoader] ClassLoader's parent class is [class org.apache.catalina.loader.StandardClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$AppClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$ExtClassLoader] Inside the debugger: [EMAIL PROTECTED] ClassLoader's class is [class sun.misc.Launcher$AppClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$ExtClassLoader] Is there a way that I can prevent the WEB-INF classes from being loaded by the System classloader when using the debugger? I know this was part of the servlet spec as the Tomcat documentation notes: The web application class loader diverges from the default Java 2 delegation model (in accordance with the recommendations in the Servlet Specification, version 2.3, section 9.6). When a request to load a class from the web application's WebappX class loader is processed, this class loader will look in the local repositories first, instead of delegating before looking. So why isn't WebbappClassLoader loading the WEB-INF/classes when debugging? Thanks in advance for your help!

Re: WEB-INF/classes not loading from corrrect classloader
It happens inside the debugger (Eclipse). Basically, what I have come to realize is happening is that Eclipse implicitly includes the current project (in my case the web-app) in the system classpath. So when I start tomcat by invoking Bootstrap.main thru the debugger, the project/application classfiles are always going to be loaded by the application/system classloader, not the webapp classloader. I found a plugin by sysdeo.com that solves this by calling bootstrap indirectly, so as not to include the application in the system classpath.

So, from what I see hear, patching a WEB-INF/lib JAR file with a overriding class in the WEB-INF/classes directory will work as anticipated? It's done at a per-class (or per-resource if you've got embedded resources) level, rather than per-package. Incidentally, Tomcat implements the exact same algorithm for the shared class loaders as well: - Classes in $CATALINA_HOME/shared/classes override classes in JAR files under $CATALINA_HOME/shared/lib - Classes in $CATALINA_HOME/common/classes override classes in JAR files under $CATALINA_HOME/common/lib. I never know how much caching of lookup Java is allowed to do with class lookups, or whether it does any at all (though I do assume it caches the directories/JARs when first visited, and does not look at those again, but perhaps that's a bad assumption). The classes and resources themselves are cached only when they are loaded. However, a related question is can I add new classes and resources dynamically while the app is running, and have them recognized? The answer for Tomcat, if you're running unpacked, is yes - but ONLY until the class has been loaded. You can't use this technique to replace an already loaded class, because Java gives us no mechanism to do that.

Re: web-inf/classes and eclipse
Hi Michenaud, using Ant together with Eclipse might be an option. You can run Ant from inside Eclipse by right-clicking the build.xml file and choosing the right operation (I now don't know how it is called). Andreas Hi, I use the editor Eclipse but when i launch Rebuild all, it deletes all the content of the WEB-INF/classes directory. Inside, there is all my *.properties file. The idea is to create a WEB-INF/config where i could put the properties files but i don't know how to add this directory into the classpath. It would be better too if the path was a relative path.

As far as I know, there is no classpath in Tomcat, but a classloader hierarchy.

Re: WEB-INF/classes
Anja, If you are using Tomcat 3.3 you need to create an XML file (apps-applicationname.xml) where you have to declare the new context where your WEB-INF directory is... Otherwise, if you are using Tomcat 3.2 or less, you have to modify the server.xml file using the new Context entry. Is something like this: Context path=/applicationname docBase=webapps/applicationname crossContext=false debug=0 reloadable=true /Context Hope this help you..

Hi Anja, To set up a new context you really only have to add a line to server.xml but just to take on the basics I take it from the start. create a folder that has a web-app structure : context / - WEB-INF/ web.xml - configuration file for this webapp -/lib/ your jar files here -/classes/your classes (compiled) here then add a line like this one : Context path=/nameofcontext docBase=C:\path_to_context_root debug=0 reloadable=true/ in to the host scope of your server.xml (suggestion beneath the one context that is already specified). if you do this, restart tomcat and you have a new context available under http://www.yourserver.com/nameofcontext/ there for the path to execute your servlets (in the classes directory of your webapplication) you should have http://www.yourserver.com/nameofcontext/servlet/nameofServlet hope it helps -reynir -Original Message- From: Anja Falkner [mailto:[EMAIL PROTECTED]] Sent: 7. febrúar 2002 22:06 To: Tomcat Users List Subject: Re: WEB-INF/classes Hi Nancy, I am using Tomcat 4.0.1.

Anja, I'm not sure, but I know that Tomcat 3.3 and later have a similar behavior.
