JDBCRealm: change password without logging out
Dear tomcat users, Can you please guide me how to let tomcat know that I have changed user password in database (JDBCRealm, Tomcat 3.2.3, form based login). I am currently altering session variable j_password but I realize this is very tomcat 3.2.3 specific and can possibly not work with future versions. Is there something in servlet api that I have not seen? with best wishes, Taavi

Tomcat and Apache, can't get it up and running
Hi, I'm trying to get the combination of Apache and Tomcat 3.3-b1 up and running, but without success till now. Both run OK themselves but when I try to access TomCat webapps via Apache nothing happens. I following the HOWTO on the jakarta site but without luck. - Accessing JSP pages by connection to port 8080 (TomCat) works fine - Accessing plain HTML via port 80 (Apache web server) is also no problem. However, I can't get Apache to forward requests to Tomcat: I used the auto config option in Tomcat and it generates a nice mod_jk.conf file in the conf/auto directory of tomcat. I added the following line to httpd.conf of apache: Include /opt/tomcat-3.3-b1/conf/auto/mod_jk.conf The contents of mod_jk.conf is: ## Auto generated on Sun Aug 19 16:47:43 GMT+02:00 2001## IfModule !mod_jk.c LoadModule jk_module /etc/httpd/modules/mod_jk.so /IfModule JkWorkersFile /opt/tomcat-3.3-b1/conf/jk/workers.properties JkLogFile /opt/tomcat-3.3-b1/logs/mod_jk.log JkMount /examples ajp13 JkMount /examples/* ajp13 JkMount /admin ajp13 JkMount /admin/* ajp13 When I try to access the examples I get the following messages in the apache log [Sun Aug 19 17:33:14 2001] [error] [client 10.0.0.150] Directory index forbidden by rule: /opt/tomcat-3.3-b1/webapps/examples/ Then I added the following to the httpd.conf file: Directory /opt/tomcat-3.3-b1/webapps AllowOverride None Options Indexes Includes FollowSymLinks ExecCGI order deny,allow allow from all /Directory But this resulted in: [Sun Aug 19 17:35:31 2001] [error] [client 10.0.0.150] File does not exist: /var/www/html/examples/ Any ideas whta could be wrong?

RE: Tomcat and Apache, can't get it up and running
Hi Gero, - Accessing JSP pages by connection to port 8080 (TomCat) works fine - Accessing plain HTML via port 80 (Apache web server) is also no problem. Ok, this is a good start =) When I try to access the examples I get the following messages in the apache log [Sun Aug 19 17:33:14 2001] [error] [client 10.0.0.150] Directory index forbidden by rule: /opt/tomcat-3.3-b1/webapps/examples/ This looks good so far, the /examples request is resolving relative to Tomcat's examples Context. Try to request an actual JSP file, not the directory. But this resulted in: [Sun Aug 19 17:35:31 2001] [error] [client 10.0.0.150] File does not exist: /var/www/html/examples/ ...exactly. Now your request isn't getting forwarded to Tomcat, and Apache is looking at it's DocumentRoot for /examples/ and it doesn't exist. - r

They want to use their own SSL accelarator however freeware geekNo doubt one they're going to charge your company for!/fg You must be joking. We're charging them :) It's just the twisted way they like to deploy things. It must detect that as it isn't doing the SSL, and the SSL accelarator has decoded the SSL stream from the user, the connection is insecure and it therefore uses HTTP and not HTTPS. I would agree. Tomcat has no knowledge that SSL is in use and returns the appropriate URL. Is there anyway to override this behaviour? Hmm... generate all URLs by hand with a custom tag? myTags:encodeURL/someDir/somePage.jsp/ ...and I don't think you'd be able to use a RequestDispatcher to forward requests either. Maybe one of the TC devs can reply if interceptors or valves or something could help. I'm not too experienced with all of this, but I figured I'd try and help out nonetheless ;) ta :) Well I can't really recode the urls. I have no problems using my own urls, infact I have an object which reads a .rc file that tells the web engine where it's deployed, so it can create links like: %= WebDefaults.ROOT_PATH + myImages/moo.gif % WebDefaults.ROOT_PATH is the path from / that this jsp is deployed. But I started using this in my novice days. I'm sure there is a method to get that for me ? :) The actualy problem is the initial redirect when the client says to the server: GET / HTTP/1.0 and the server returns a redirect to: http://whatever/index.jsp but of course that needs to be: https://whatever if the accelarator is in use.

ClassLoader Reloading issues
I have a JAR file in my web-inf\lib directory that has an object pool. The pool is kept as a singleton, so, I have a static member with it. The problem is that when a class in web-inf\classes is reloaded, it seems to use a new classloader, so the static member is gets not the same as it was, and I end having multiple object pool instances. If I put the .JAR in the Tomcat classpath, it obviously works ok. The problem is that I must keep running in the same servlet-engine instance several applications each of which could a have a different version of my .JAR file, so I can't put it in the classpath. The same happens running the app in Resin. Now, in the servlet spec says: 'Although a Container Provider implementation of a class reloading scheme for ease of development is not required, any such implementation must ensure that all servlets, and classes that they may use, are loaded in the scope of a single class loader. This requirement is needed to guarantee that the application will behave as expected by the Developer. As a development aid, containers are encouraged to maintain the full semantics of notification to session binding listeners if they determine to terminate sessions in order to reload classes. Previous generations of containers created new class loaders to load a servlet, distinct from class loaders used to load other servlets or classes used in the servlet context. This could cause object references within a servlet context to point at unexpected classes or objects, and cause unexpected behavior.' I'm not sure if this paragraph is referring to the case I'm describing, but if not, it seems pretty close... Any ideas? Is this the way it's supposed to work? Thanks.

Very early containers used a different class loader for every servlet, not for every web app. To ensure consistent behavior, this is no longer allowed. I'm not sure if this paragraph is referring to the case I'm describing, but if not, it seems pretty close... Any ideas? Is this the way it's supposed to work? Yes, it is working the way it is supposed to work (given the limitations on what Java allows for class reloading). What you need to do is make sure that your class is aware of when the application is being shut down and started up again, so that you can save away the contents of the object pool (at shutdown time) and restore them (at startup time). At shutdown time, you'll need to save the state of the object pool in some fashion that can be used to reconstruct it upon the subsequent startup. A common technique is to serialize the pooled objects to a sequential file (Tomcat 4 does this with all of the currently active sessions when you shut it down or do an application reload). To make sure your object pool class is notified, you've got a couple of choices: * [Servlet 2.3 only] You can use the new application event listener APIs and make sure your class is notified on the application startup and application shutdown events. This will work in Tomcat 4 and other containers that implement the new servlet spec. * You might have a servlet defined as load-on-startup that initializes the object pool in its init() method and saves it away in its destroy() method. This depends on the servlet container *not* removing this servlet from service at any time *other* than application shutdown -- while commonly implemented that way, this is not guaranteed by the servlet spec (it would work in all versions of Tomcat, though). Thanks. Craig McClanahan

Re: ClassLoader Reloading issues
somewhat related issue I've found with T3.2.2. After class reloading the old class isn't GC'ed, is a reference to previous class that's kept around somewhere? Actually I noticed it because I had a cleanup thread running infinitely, and after the class reload I ended up having two threads running. Could also be that runtime keeps a reference to a running Thread (which is the inner class) preventing a class (outer class) from being GC'ed? Sounds like a good explanation... --V. - Original Message - From: Craig R. McClanahan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, August 19, 2001 8:25 PM Subject: Re: ClassLoader Reloading issues On Mon, 20 Aug 2001, Andrés Aguiar wrote: I have a JAR file in my web-inf\lib directory that has an object pool. The pool is kept as a singleton, so, I have a static member with it. And because the class itself is loaded by the webapp class loader, the static is in fact global *only* within this particular web app. The problem is that when a class in web-inf\classes is reloaded, it seems to use a new classloader, That's correct -- there is no way to unload a class in Java except for throwing away the class loader that loaded it (and therefore all of the classes loaded by that old class loader). so the static member is gets not the same as it was, and I end having multiple object pool instances. If I put the .JAR in the Tomcat classpath, it obviously works ok. The problem is that I must keep running in the same servlet-engine instance several applications each of which could a have a different version of my .JAR file, so I can't put it in the classpath. The same happens running the app in Resin. Now, in the servlet spec says: 'Although a Container Provider implementation of a class reloading scheme for ease of development is not required, any such implementation must ensure that all servlets, and classes that they may use, are loaded in the scope of a single class loader. This requirement is needed to guarantee that the application will behave as expected by the Developer. As a development aid, containers are encouraged to maintain the full semantics of notification to session binding listeners if they determine to terminate sessions in order to reload classes. Previous generations of containers created new class loaders to load a servlet, distinct from class loaders used to load other servlets or classes used in the servlet context. This could cause object references within a servlet context to point at unexpected classes or objects, and cause unexpected behavior.' Very early containers used a different class loader for every servlet, not for every web app. To ensure consistent behavior, this is no longer allowed. I'm not sure if this paragraph is referring to the case I'm describing, but if not, it seems pretty close... Any ideas? Is this the way it's supposed to work? Yes, it is working the way it is supposed to work (given the limitations on what Java allows for class reloading). What you need to do is make sure that your class is aware of when the application is being shut down and started up again, so that you can save away the contents of the object pool (at shutdown time) and restore them (at startup time). At shutdown time, you'll need to save the state of the object pool in some fashion that can be used to reconstruct it upon the subsequent startup. A common technique is to serialize the pooled objects to a sequential file (Tomcat 4 does this with all of the currently active sessions when you shut it down or do an application reload). To make sure your object pool class is notified, you've got a couple of choices: * [Servlet 2.3 only] You can use the new application event listener APIs and make sure your class is notified on the application startup and application shutdown events. This will work in Tomcat 4 and other containers that implement the new servlet spec. * You might have a servlet defined as load-on-startup that initializes the object pool in its init() method and saves it away in its destroy() method. This depends on the servlet container *not* removing this servlet from service at any time *other* than application shutdown -- while commonly implemented that way, this is not guaranteed by the servlet spec (it would work in all versions of Tomcat, though).

tomcat and jdbc

I have tried to go to the tomcat conf file looking for server.xml To enable the jdbc realm to be loaded but Tomcat is not connecting to jdbc. Please help...
