Yes, TC 5.5 still has the server ClassLoader, so the RequestFacade is loaded
in a ClassLoader that isn't the parent of your ClassLoader. You need to do
one or more of the following:
1) upgrade to TC 6.0 so that the Request and RequestFacade are in your
ClassLoader hierarchy (in the default settings)
2) declare your webapp 'privileged' in your context.xml (giving access to
the server ClassLoader).
3) I think all the info that you want is exposed by JMX, so use JMX to
retrieve it.
4) use introspection to grab the fields. On 5.5 this will be painful, since
you have to use introspection everywhere (none of the classes will be in
your ClassLoader hierachy)
5) change your catalina.properties file to have the same hierachy as TC 6
(but will get over-written on upgrades).

No, without a SecurityManager, you can do pretty much anything with
introspection by at most calling field.setAccessible(true). This is how the
WebappClassLoader nulls out static fields when you undeploy a webapp. It's
also a big part of the reason that the server ClassLoader went away by
default, since it didn't really stop anyone from accessing Tomcat core
classes.

RE: Class loading question (with aspectj)
I don't explain well. I appologize for it. Those .java source were already compiled into .class file (I use maven I checked the war file. Class files are stored in the correct path.) It just looks like the webapp class loder doesn't load the aspectj class (whose source is ended with .aj and it is compiled into .class after packaged into war file.) But I think I could be wrong because I am not very sure whether the WebappLoader.java/ WebappClassLoader.java are the right place to look at. Just want to collect as many information as possible in order to find out what happends. It is interesting for me to understand more on how it works. Thanks again for your reply.

Realm configuration issues
Hi, I have been trying to implement form based authentication using container managed security. I had tried originally to use the DataSource Realm but after struggling with that for so long I gave up because I had tried everything I could think of as far as putting the Realm declaration in varioius places with no luck, and I got conflicting answers between the the Apache-Tomcat docs ( which I've read multiple times) and what I found in places like mark-mail and nabble. So now I am trying to get it working with the JDBC realm instead. I have a simple webapp for mountain bike and trail reviews and bicycle reviews. In order to submit a new review you need to log on or register. Here is my server.xml: And my web.xml: http://www.w3.org/2001/XMLSchema-instance"; xmlns=" http://java.sun.com/xml/ns/javaee"; xmlns:web=" http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"; id="WebApp_ID" version="2.5"> project-1c index.html index.htm index.jsp default.html default.htm default.jsp com.buzz.TrailsAppServletContextListener find trails based on category TrailFinderServlet TrailFinderServlet com.buzz.finder.TrailFinderServlet TrailFinderServlet /TrailFinderServlet TrailReviewSubmitServlet TrailReviewSubmitServlet com.buzz.review.TrailReviewSubmitServlet TrailReviewSubmitServlet /TrailReviewSubmitServlet TrailReviewServlet TrailReviewServlet com.buzz.review.TrailReviewServlet TrailReviewServlet /TrailReviewServlet bikeFinderServlet bikeFinderServlet com.buzz.finder.bikeFinderServlet bikeFinderServlet /bikeFinderServlet BikeFinderServlet BikeFinderServlet com.buzz.finder.BikeFinderServlet BikeFinderServlet /BikeFinderServlet 10 admin member guest UpdateTrails /* GET POST These are the roles who have access admin FORM Tomcat Server Configuration Form-Based Authentication Area /Login.html /auth-error.html DB Connection jdbc/trailsDB javax.sql.DataSource Container Even though it says DataSource in the above resource-ref tag, all the info I found told me to do that even with the JDBCRealm. So there seems to be 2 problems. Here's what Tomcat gives me when I attempt to login: HTTP Status 404 - /blurbV1/auth-error.html -- *type* Status report *message* */blurbV1/auth-error.html* *description* *The requested resource (/blurbV1/auth-error.html) is not available.* -- Apache Tomcat/6.0.16 But it should allow me to login since I have the users and the database setup with the correct user and role tables. Here is the tomcat-users.xml created by Tomcat: Any ideas why I might be getting this ? Thanks, Adam

Go ahead and re-post your entire conf/Catalina/localhost/UMI.xml and web.xml from your webapp. Also, it wouldn't hurt to stop Tomcat, remove the entire 'work' directory from CATALINA_BASE (the root of the Tomcat install), and re-start Tomcat, just in case something is being inadvertently cached in there. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqhOXIACgkQ9CaO5/Lv0PAv5wCdFFcgXjtr836UYd251fNAy2GZ 8ngAn0FdAlstoJ2Z5yLq12lM8LL7iDbX =EoZC -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: how to unwrap a Request from RequestFacade
Thanks Chris. Still not having any luck. Let me give you the snippet of
the code so that you can understand the problem better:
I have a servlet like this
protected void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
// some code
RequestFacade rf = (RequestFacade) request;// this
throws a class cast exception
Request realRequest = new
MyRequestFacade().getRequest(rf);
Context ctx = _realRequest.getContext();
StandardManager sessionMgr = (StandardManager)
ctx.getManager();
sessionMgr.getActiveSessions();
}
When I debug I see that the request object coming into doGet method of the
servlet is RequestFacade but I can't assign it directly to a RequestFacade
object or can't type cast it. Although when I type cast it I don't get any
compilation error but at runtime it throws as a ClassCastException.
Am I doing something stupid here? :-( Looks simple it is so frustrating as
when I debug I can open the RequestFacade object and see the Request
Object, Context, Manager and all the information I need but I don't know
how to access it.
Any thoughts from fresh pair eyes?

I had thought about that, but I thought the JVM prevented code from
getting-around access privileges by using introspection. Or is that only
when a SecurityManager is running?

Go ahead and re-post your entire conf/Catalina/localhost/UMI.xml and web.xml from your webapp. Also, it wouldn't hurt to stop Tomcat, remove the entire 'work' directory from CATALINA_BASE (the root of the Tomcat install), and re-start Tomcat, just in case something is being inadvertently cached in there. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkqhOXIACgkQ9CaO5/Lv0PAv5wCdFFcgXjtr836UYd251fNAy2GZ 8ngAn0FdAlstoJ2Z5yLq12lM8LL7iDbX =EoZC -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: Unable to Access Servlet After Migrating From Tomcat 5.0.25 to 6.0.18
Chris, I tried your suggestion and replaced the trailing / in the url-pattern of the servlet-mapping tag with *, but got the same result. I even tried commenting out servlet-mapping altogether, but still received the file not found exception. The HUSim class is part of an application that I wrote years back to test servlet functionality, and it has worked up to and including servlet deployment in 5.0.25. I removed the trailing /, rebuilt the application, and ran it again, with the same result. I strongly believe it may be a mapping issue, but I just can't seem to nail it down.

I had thought about that, but I thought the JVM prevented code from
getting-around access privileges by using introspection. Or is that only
when a SecurityManager is running?

Re: /context not working -- mod_jk error: no match for /server-status
Rainer, Apparently apache is calling /server-status - I see that mod_status is enabled in httpd.conf and exercises that context. One of the frustrations, and I dont know Apache well, is that the access log seldom updates. The error log in the same folder does update, but contains little information--apache restarts is about it. I don't know if this helps, but I just tried to access the sample web app from the server machine's own browser httpd://localhost/sample and I get "Bad Gateway! The proxy server received an invalid response from an upstream server Error 502 locahost and this does update the access log.

Can't fully undeploy a servlet application in Tomcat 6.0.18
I'm using the Tomcat Web Application Manager to deploy and undeploy servlet applications on a Windows 2003 server box. Sometimes, not all of the files are deleted from the application directory during an undeploy, because something has them locked. The files that are locked are one or more HTML files. When this happens I need to stop Tomcat, manually delete the application directory, then restart Tomcat and deploy the new version. Are there any options that can be set in a Windows environment, that will prevent this from happening? Thanks, Jon Oman

Unable to Access Servlet After Migrating From Tomcat 5.0.25 to 6.0.18
I am attempting to migrate a servlet from Tomcat 5.0.25 to 6.0.18, but
my efforts to access it while running under 6.0.18 have been
unsuccessful. The servlet is accessed on the server via HTTP, but has
web interfaces for simple testing and to check servlet loading and
client-server message traffic.
The context.xml and web.xml files as described are similar to what we
have running under Tomcat 5.0.25. Aside from the connector and shutdown
ports, the server.xml file is the same one that was bundled with 6.0.18.
We can access the servlet while running under 5.0.25, but not 6.0.18.
It is probably a simple configuration file or security setting that I
have not been able to locate.
The servlet is initialized by a context file placed in
{$CATALINA_HOME}/conf/Catalina/localhost. Tailing the catalina.out
file, I have confirmed that the servlet context is being loadet at
Tomcat startup. The context path is set to my home area for testing,
but is similar to what we use for production deployment, i.e., it is not
deployed from {$CATALINA_HOME}/webapps. Here are the contents of my
context file:

jkstatus - Error connecting to tomcat - ajp_process_callback write failed
Hello everybody, i got many errors about mod_jk but i don't know whether it's the good forum ... I have configured 4 tomcat identical servers reached by a front server apache through mod_jk. When I look at the jkstatus page, I can note a strange behaviour: only the same server (4) is under loaded. Regular percentages are: 1st:30% , 2nd:29%, 3rd:28, 4th:13% (note: lbfactor is the same for the 4 workers) I don't know which way I can scrutinize. I just can see a lot of errors within error.log: "Error connecting to tomcat" (not necessarily the 4th) or ajp_process_callback write failed. So, the question is, which are the first checkings at tomcat configuration I can do ? Do you have an "how to" for interpreting jkstatus ? or is there any other way, a kind of pure tomcat tool, to check the tomcat perfs. Thank you very much jl
Re: Class loading question (with aspectj)
I do not put the same class i.e. TapestryFilter.java in both location (WEB-INF/classes and WEB-INF/lib). The way how I test is by copying TapestryFilter.java to another foler under WEB-INF/classes and renaming it to another name e.g. MyTapestryFilter.java. Then configure web.xml to use MyTapestryFilter in ... tag. The aspectj code will get printed if web.xml uses MyTapestryFilter class, but those code won't be printed if web.xml use default TapestryFilter class. I look up the source code and just notice one thing that makes me confused. My aspectj code e.g. FilterInterceptor.java is located under WEB-INF/classes folder and TapestryFilter.java is packaged as lib and located under WEB-INF/lib folder. What caught my attention is when I startup tomecat server version 6.0.20 (I build it from scratch), the WebappLoader.setRepositories() looks like does not load FilterInterceptor.java because it doesn't show e.g. FilterInterceptor.java get loaded (or it is because setRepositories only load jar files?) as below. ---> WebappLoader.java: setRepositories(): WEB-INF/classes/ loaderRepositories:[/WEB-INF/classes/] -> WebappClassLoader.java: addJar(): jarRealFiles.length:0 Then it starts to laod jar files under WEB-INF/lib ---> WebappLoader.java: setRepositories(): WEB-INF/lib loaderRepositories:[/WEB-INF/classes/, /WEB-INF/lib/antlr-2.7.6.jar] -> WebappClassLoader.java: addJar(): jarRealFiles.length:1 -> WebappClassLoader.java: addJar(): jarRealFiles[0]:/home/jackson5/app/apache-tomcat-6.0-snapshot/webapps/jecommerce/WEB-INF/lib/antlr-2.7.6.jar ... Does this mean the class ( compilied aspectj code ) is not loaded? Or where should I look up so that I can check if it is because the tapestry jar files get loaded, but not my aspectj code (located under WEB-INF/classes)? I appreciate any suggestion.

What is the class loading order if the classes are located under > /WEB-INF/classes/ and /WEB-INF/lib/ respectively? The search order is always: /WEB-INF/classes /WEB-INF/lib You can distribute your classes between those locations any way you like but if you put the same class in both locations, the one in classes will always take priority.

why datasource get an already closed connection?
Hi buddies, I want to ask a question about connection pool, and my environment is apache-tomcat-5.5.27, mysql-5.0.67(mysql-connection-j-5.1.8) and default apache DBCP. Here is a short description of the problem I met. I configured a datasource in $catalina.base/conf/server.xml, and get a connection in my java code. url="jdbc:mysql://localhost:3306/xxx?useUnicode=true&characterEncoding=utf8" username="xxx" /> I can do all the operations using that connection. while, when I logout the application, and wait for a long time, about a whole day, and then an error will occur when I login again. The SQLException message is something like this: 2009-09-03 14:04:32,046 ERROR [xxx.xxx.xxxDao].[login] Communications link failure The last packet successfully received from the server was 1,398,531 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. 2009-09-03 14:04:52,062 ERROR [xxx.xxx.xxx.common.DatabaseUtils].[closeQuietly] Already closed. OR 2009-09-03 16:05:37,703 ERROR [xxx.xxx.xxxDao].[login] No operations allowed after connection closed.Connection was implicitly closed due to underlying exception/error: ** BEGIN NESTED EXCEPTION ** com.mysql.jdbc.exceptions.jdbc4.CommunicationsException MESSAGE: Communications link failure The last packet successfully received from the server was 910,485 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. STACKTRACE: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 910,485 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago. .. so, I think the error is because I am using an already closed connection. and I have to wait a really long time to re-create this exception. After doing some googles, I found that there is an wait_timeout parameter in mysql: By default, the server closes the connection after eight hours if nothing has happened. You can change the time limit by setting the wait_timeout variable when you start mysqld. so, I think it because DBCP get the connection with the following way: The pool can be configured to behave as a LIFO queue with respect to idle objects - always returning the most recently used object from the pool, or as a FIFO queue, where borrowObject always returns the oldest object in the idle object pool. lifo determines whether or not the pool returns idle objects in last-in-first-out order. The default setting for this parameter is true. so, if 8 hours later, the mysql server closes the connection used the most recently in the pool ,then when I login again, I get an already closed connection, when I use it to do some operations, error occurs. Now I have some ways to solve it: First of all, I check the connection I get from the pool, if it has already closed, I set it to null, and get another one from the pool. Secondly, I add validationQuery="SELECT 1", which seems working well. Thirdly, I change the mysql wait_timeout to the max value, which can be 365 days. Who can give me any advice to solve this problem in another way or tell me which is the best way among the ways I talked about?
