Tomcat IO exception on startup

Web.xml entries
Hi, I have a basic question about the tomcat server start-up. If there are classes missing that are referenced as servlet entries in the web.xml should this render the server unuseable? I did a little test today with a web app, and when tomcat started it reported class not found exceptions for the missing classes, and I could no longer get to the login page for the web app which is a jsp. When I fixed those errors the login page displayed fine. The error I got was resource not available (tomcat error page), I am using tomcat 5.5.

Tomcat and jar loading
Hi, I have a brief question regarding the way tomcat loads jar files. Are the references to all jar files in common\lib and shared\lib loaded on server startup? I know classes are loaded once they are requested, but I added a new jar file that was never there before (so no classes were loaded) and I couldn't reference the classes. Is this because the classpath that tomcat uses references every single jar file, and the jvm needs to be stopped in order for the new jar file to appear on the classpath? I just bought a tomcat book, so hopefully I can stop asking these silly questions soon!! Cheers ** This message may contain confidential and privileged information.

Environment Variables
Hi, Can anybody tell me which environment variables tomcat uses? I am pretty sure it uses JAVA_HOME for core java, and I am guessing it uses the web application directories for classes belonging to web apps under it. The reason I am asking this is that I have a jar file clash on my development machine, and when I try to run a certain class I get the error: java.lang.LinkageError: loader constraints violated when linking javax/xml/rpc/Service class. I am pretty sure this is because I have 2 copies of a class located in different jar files, I googled this and a lot of links point to CLASSPATH, but my CLASSPATH variable doesn't really have anything in it: C:\Program Files\gemplus\gac\GATicket.jar;C:\Program Files\gemplus\gac\iaikPkcs11Wrapper.jar Appreciate any help.

RE: Possible to assign different class loader for each web app with tomcat
Ok, that's strange because yesterday I had a small problem, and I assumed that it was due to the same class being loaded on startup by 2 web apps. I had a url endpoint loaded into a config class on startup from the web.xml, for some reason no messages were reaching the correct end point. This config class is also loaded by a test version of the app running under the same tomcat as pre prod. When the second web app was loaded and its config class was loaded and the parameter read in from the web.xml it changed the value for both web apps. I have not being using java or tomcat for all that long, but I would have thought if a class loader was assigned for each web app then they would each have their own copy of the config class? Meaning that web app1 should not have been pointing at the end point for web app 2? If not then could you tell me why?

RE: Possible to assign different class loader for each web app with tomcat
Thanks for the reply. To be honest I am not sure, both web apps are separated, have their own web.xml files and also are accessed via different ports, however as they are effectively the same application at different stages of development they each need to load parameters in on start up to a class that holds constant values. (I dont know if this is the best or a good way to do it, its how it was done before I started).

Unless, of course, you specified a specific classloader to use by tomcat in your context.xml.

I had a url endpoint loaded into a config class on startup from the web.xml, for some reason no messages were reaching the correct end point. This config class is also loaded by a test version of the app running under the same tomcat as pre prod. When the second web app was loaded and its config class was loaded and the parameter read in from the web.xml it changed the value for both web apps. I have not being using java or tomcat for all that long, but I would have thought if a class loader was assigned for each web app then they would each have their own copy of the config class? Meaning that web app1 should not have been pointing at the end point for web app 2? If not then could you tell me why?

RE: Possible to assign different class loader for each web app with tomcat
Ok thanks, it's starting to become clearer now. The class file is in a jar file that lives in tomcat\shared\lib. I am guessing that these classes are loaded by a class loader further up the hierarchy described in the tomcat docs. I suppose in this instance there would only be one class loaded? I guess if this is the case the only thing confusing me is why this class is actually loaded by tomcat when it doesn't have to be? Does the load-on-startup1/load-on-startup tag not load a class specifically for this web app regardless of where the class file might be? Thanks for the help by the way. -Original Message- From: Mark Thomas [mailto:[EMAIL PROTECTED] Sent: 09 May 2008 12:25 To: Tomcat Users List Subject: Re: Possible to assign different class loader for each web app with tomcat [EMAIL PROTECTED] wrote: Thanks for the reply.

RE: Possible to assign different class loader for each web app with tomcat
Thanks for the replies, I think I understand what is happening now, I think for safety's sake I will use a separate config file for each web app instead of trying to share one between them all and load separate copies. Thank you. -Original Message- From: Mark Thomas [mailto:[EMAIL PROTECTED] Sent: 09 May 2008 13:41 To: Tomcat Users List Subject: Re: Possible to assign different class loader for each web app with tomcat [EMAIL PROTECTED] wrote: Ok thanks, it's starting to become clearer now. The class file is in a jar file that lives in tomcat\shared\lib. I am guessing that these classes are loaded by a class loader further up the hierarchy described in the tomcat docs. I suppose in this instance there would only be one class loaded? Correct. The class would be loaded once but that doesn't prevent multiple instances of the class being created. However, I suspect the class in question uses the singleton pattern so there is also only once instance. This instance will be shared between all webapps. I guess if this is the case the only thing confusing me is why this class is actually loaded by tomcat when it doesn't have to be? Does the load-on-startup1/load-on-startup tag not load a class specifically for this web app regardless of where the class file might be? No. load-on-startup requires Tomcat to load the servlet when the context starts and the number dictates the order (as per the spec). The class loaders will be searched in the order described in the docs and the first instance found of the class will be used. If (as it appears from your description) you have webapp specific information being held in a singleton class then you *must* place that class in WEB-INF/classes or the jar containing it in WEB-INF/lib shared/lib is for classes that can be safely shared between multiple webapps. Personally I never used it. It generally caused more problems than it solved - one of the reasons it is removed by default in 6.0.x onwards. Thanks for the help by the way. No problem.

Multiple web apps on different ports under one tomcat

RE: Multiple web apps on different ports under one tomcat
Hi Ben, Firstly thanks for replying, it could be that my file is not arranged in the most suitable order then, I might have tags inside other tags when they don't need to be (could be shared by both services?). I have pasted my server.xml into this email, if you could take a look at the order of the tags I would be grateful. If you spot anything wrong then could you let me know.
