Class loading from within a servlet: interface definition not found
I have something happening with class loading from within a server, and I don't understand it. My servlet defines some classes called: org.something.server -- the class that extends HttpServlet org.something.DatabaseRequestHandler -- an interface When you make a request to the server, it figures out what handler class to load. Then it attempts to load it: Class handlerClass = Class.forName(handlerClassNameString); QUESTION: looking at the little diagram in the Tomcat 5.5 Class Loader HOW-TO, when I do the above (Class.forName) I am using the Webapp class loader, correct? The handler classes are all in handlers.jar which is in $CATALINA_BASE/shared/lib. The actual exception that I get is: 2006-04-28 17:05:55 StandardWrapperValve[xdb]: Servlet.service() for servlet xdb threw exception java.lang.NoClassDefFoundError: org/something/DatabaseRequestHandler It took me a few minutes to realize that this was not a ClassNotFound exception, but something else. Reading docs I figured out that the most probably cause is that the servlet's classloader was able to find the handler class, but then it failed to load one of the things it depended on, specifically it was able to find handlerClass but not the interface class that it depends on. Trouble is: the interface .class file is right there in WEB-INF/classes/com/something/DatabaseRequestHandler.class just like it should be. So, I am stumped why the class loader would be able to find the handler class in $CATALINA_BASE/shared/lib but NOT the interface that it implements which is in WEB-INF/classes. At the suggestion of a nice gentleman on freenode, I tried turning on the -verbose:class option in the jvm, and watched it log some interesting stuff to catalina.out. Unfortunately it doesn't shed any light on what is happening, beyond the exception and stack trace in the error log. I don't want to post the whole stack trace (unless someone thinks it would help to see it) but I will say that it includes catalina.loader.WebappClassLoader as well as catalina.loader.StandardClassLoader --Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: can't access database after timcat idle for several hours
2006/4/28, David Kerber <[EMAIL PROTECTED]>: Sounds to me like your database is timing out the connection. See if you can extend the timeout so it won't drop it during an overnight lull. This seems probable, indeed. I would recommend setting up some kind of connection checking, that would make some traffic round-trip between the servers.

can't access database after timcat idle for several hours
I am running 3 servers; Apache, Tomcat (5.5.16, java version "1.5.0_06", Informix JDBC-1.3.00.JC3) and Informix (7.31.UD2). After the app has been idle for several hours tomcat cannot access the database. Netstat shows not connections to the database and tcpdump shows no traffic at all going the database when queries are made to the app (which would cause the database to be consulted) At first it seemed that the overnight backup of the database was causing this problem but restarting tomcat after the backup only fixes this problem for a few more hours. I wrote a loop to wget url's that cause the database to be consulted every 60 sec but after several hours this problem happens again. Tomcat seems to be fine, I can load the management page and restart the app. Only restarting tomcat fixes this problem, reloading the app does not fix the problem.. Nothing is being logged during and right before this problem. Does anyone have suggestions to further debug this problem ? -- James H.

Re: Changing tomcat's group
Solved!!! The solution is to use the linux group sticky bit to force any files created in a directory (and subdirectories) to have the same group as the parent. For example let's say there are two applications, one for accounting and one for payroll. If you create a directory for accounting and one for payroll, each belonging to their own group and tomcat belonging to both groups, then tomcat can read the files in both directories but when it creates a file, it ends up being tomcat user and tomcat group. If you change the settings on the two directories as follows: chmod g+ws /accounting chmod g+ws /payroll then when files are created in either directory, they will have the same group ownership as the directory. Problem solved. Thanks for those who commented. Aria. On Thu, 27 Apr 06 16:55:40 -0400 Aria Bamdad said: >Hi, > >I have several applications running in different directories.

RE:Blank Page after tomcat install
Daren, Steve, and David, Thanks for the response. 1) I am just doing a straight tomcat, no web server. 2) The logs seem to be useless in this case. However I will post them at the end of my message. 3) I've messed around a little more and become more confused. First I was trying to get 5.5.17 to work, but realizing that the Tomcat I set up a couple of weeks ago was 5.5.16, I decided that I would use that tar and try and duplicate my earlier success. I unpacked the 5.5.16 and tried the following in the browser: localhost:8080 --- blank page localhost:8080/jsp-examples -- got the examples page, able to run the examples localhost:8080/servlets-examples - got the servlets example page localhost:8080/webdav -- get the index list So I stopped the 5.5.16 and restarted the 5.5.17 and tried the same thing with the following results: localhost:8080 --- blank page localhost:8080/jsp-examples -- got the examples page, only can run some examples, other give blank page localhost:8080/servlets-examples - blank page localhost:8080/webdav -- blank page So I decided that I would try what I was really after, and work on the JSF tutorial that I found via the my-faces page using 5.5.16 since it seemed to work better than ...17. I installed the my-faces examples and they worked, and I did part of the tutorial and it works. So I can server up jsp's with no problem apparently, just not the first one To get the logs below I emptied the log directory. Started the 5.5.16 instance of Tomcat, opened a browser and typed in the 4 urls above.

Bob, making each app owner a member of the tomcat group will allow different app owners to look at each other's files. For security, I need to keep each applications files secure from the other. So, I can't add each owner to the tomcat group. Even so, the application owner needs to have read/write access to the files created which makes matters more complicated. What I need is to either have tomcat create the files using the appropriate group by maybe having tomcat do a 'newgrp' before executing an application request. Is this possible? Is there a way to do a post- or pre- script before running a request in tomcat? Thanks.

The files are in separate directories and each apps root directory is owned by the group that owns the app, however, when the application creates a file (using tomcat) the files newly created have tomcat-tomcat owner/group. Tomcat belongs to the groups for all the different applications but the application owners do not belong to the tomcat group. Setting the directory group ownership on Linux does not seem to force the files within it to have the same ownership.

It's not saying restrict access to the ajp listener to localhost. If it's bound to the loopback interface only, then only local applications will be able to connect to it. Nothing else can access 127.0.0.1. Try it, and then try using telnet i.p.add.ress 8009 from a different machine You should get connection refused. I'm fairly confident that this solves your problem. Chris Thanks, I know what you mean but my problem is the Apache is not on the same box as the Tomcat.

Re: Servlet and Tomcat question
Hi Adam, Hello, I noticed something with Tomcat that is probably obvious to everyone but me, but I gotta ask about it. Im a total novice at programming so please be patient. After starting up Tomcat today I began writing a script to use on Tomcat without being connected to the web. The dos window was sitting in on my toolbar for a while until I finished the program. I ran the servlet via Tomcat and it appeared to work as expected. I maximized the dos window for my instance of Tomcat and noticed the screen was filled with 'false' statements. It looks like a bunch of print statements of a boolean variable that I do not think I coded in my program. Was I just programming for a while, and Tomcat is just pinging itself in a way.. or did I do something wrong? Any help would be much appreciated. Thanks! Can you please send this error statements? -- Franck -- Dipl.-Hyd.

Re: Is there a clean way to add Custom protocol endpoint to tomcat 5.5

My problem is to fin a way to starts MY protocol endpoint when Tomcat boots. I don't want to put the code in my webApp, since I can have several webapps on the same server. I looked into server.xml to find a way to starts it... I tought Connector would be suitable for my needs but it seems strictly related to HTTP request handling. In theory, you can write a ProtocolHandler for any protocol you like and plug it into the Connector. However, you are right that this is for Request processing. Is server.xml supports a custom protocol Handler? For what I looked it seem to be predefined connector one for HTTP, HTTPS and AJP/1.3. If it possible in some way to hook by there I can live whith the fact that is not the way that supposed to be used :-) enableLookups="false" redirectPort="8443" protocol="AJP/1.3" /> You could take a look at Tribes (container/modules/groupcom in the 5.5.17+ source distro/SVN co). It's still a work-in-progress, but it may let you do what you want. Thanks for the info I'll look into it! Best Regards /David I hope to find a way without changing the tomcat code base.

Won't that do it? Chris I don't think so because that's saying, bind the ajp listener to the localhost. It's not saying restrict access to the ajp listener to localhost. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Restricting access to Tomcat
Hi, I have an Apache mod_jk Tomcat server set up on the same host, and want to restrict access to the Tomcat so that only the Apache on the localhost can connect to port 8009. I tried using org.apache.catalina.valves.RemoteAddrValve, with allow="127.0.0.1", but the issue is that Tomcat picks up the IP address of the client, and not the Apache which is passing traffic onto it. Is there a way round this? Thanks, Ed. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat 4.1.30 - Languages of messages are mixed up
After starting Tomcat 4.1.30 the language of messages are mixed up (between English/German) in the Web-Application (s). This problem occurs not always, but sometimes! The Web-Application uses struts. The standard-language is German (msg.properties). The Server is installed in English (Windows 2000 SP4). Tomcat is installed as service. Are there some ideas how to fix tis problem?
