Re: combination of RemoteAddrValve und basic authentication
Hi Chris, but allows is part of RequestFilterValve. Not in the current trunk. Your code expects the allows variable to be of type String[], and no such variable exists in RequestFilterValve. Right: the point of the RequestFilterValve is that you don't have to override the process() method. Overriding it kind of defeats the purpose of the class, because it really doesn't have any other methods other than the accessors and mutators for the 'deny' and 'allow' properties. I only mentioned once, that I use Tomcat 6: And there is an allows attribute and an additional method precalculate.

control of session timed out with tomcat
Hi my friends, I want to ask you all, If there is a way to control the timed out of sessions with tomcat, what I need is when the session timed out, automatically the user is redirected to the login page, Is this possible to do that from tomcat?, I mean, tomcat triggers some event to the user with session timed out, with no need user interaction. I know that the time of inactivity of the session is setup in web.xml, with that I have no problem, what I need is just redirect to a login page when the session timed out. I am working with tomcat 7.0.20 and JDBCRealm for authentication. Thanks in advance. -- Alejandro Soto M.

Actually, it does. That's what session listeners depend on.
So, for example, I can have a ShoppingCart with a method like
public void valueUnbound(HttpSessionBindingEvent httpsessionbindingevent)
{
empty(); /* remove reserved status from items */
}
If the session times out without the cart contents being purchased,
the cart returns any items it contains to inventory. Very handy :-)

It is handled by the background processing thread. By default that
thread runs every 10 seconds and ManagerBase triggers a session
expiration check every 6 runs by default. So in short, they are checked
roughly every 60s. The test is pretty simple so it doesn't take very
long at all.

I forgot to mention this Apache server does that. My reading suggests that it controls mod_proxy, which should be the same for all mod_proxy_*. The documentation for mod_proxy_ajp is woefully slim. Sure, you can learn all about the AJP protocol, just not how to configure the proxy in httpd.conf :( We have started series of tests to determine the effect of the following changes; 1. Upgrade Apache to 2.2.21 (the latest) 2. Upgrade Tomcat to 5.5.34 (the latest in the 5.x series) 3. Remove *SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1* It will take a while to complete these tests whch has to do with our test methodologies, which could be summarized as make one change and repeat the baseline test at least twice. I'll definitely take out these settings, because the http proxy connections should also be persistent. Okay. Did it work? Seems like a simple test to make. Regarding the upgrade of the Tomcat server we might not be able to do that. The application hosted by Tomcat has dependency on the Tomcat 5.5.x version which limits our options. I'll need to determine yet which version would be compliant with our application. If you have dependencies on Tomcat code, it's best to replace those with standards-compliant code. Maybe we could help with that kind of thing. As for 5.5 - 6.0 - 7.0 upgrades, I have recent done that exact thing and have had no problems whatsoever. Tomcat *should* be backward-compatible with previous releases, but there are some gotchas to be found when the TC code has become more spec-compliant or more cranky about certain bad configurations that it used to allow. As with any upgrade, always read the release notes / changelog carefully. The application that is deployed on Tomcat 5.x is called Sakai ( http://sakaiproject.org/). From what I know it has strict dependencies on the Tomcat version. We started reviewing the requirements for the migration to Tomcat 6.x but this will take a while, probably months to complete. I am also considering to install Apache Portable Runtime to improve connectors performance and determine its effects on the persistence of the proxy connections. What do you think? If you expect high concurrency, try using the NIO connector(s): they should scale better and have the advantage of being all Java, so you have less risk of crashing your JVM if something goes wrong (though the APR AJP connector /is/ pretty rock-solid). This is also in our test plans but this change has to wait on the result of the servers upgrade tests. Moving to NIO or APR seems a sensible thing to do. The Apache server does more than being a reverse proxy for this Tomcat server and couldn't be removed from the server configuration of this application.

Of course, this would require a dedicated thread. If the background
thread handles more tasks than just expiring sessions there's probably
not much gain in doing this approach. Or you could use the 'find oldest
session' value to compute how many work cycles to skip until the next
actual check. Is the complexity worth the savings in CPU cycles? Eh,
probably a wash. Could set a minimum threshold and only use the computed
value if it's greater than the threshold. Incorporate the computation as
part of the session scan.

One node needs to have watchEnabled=true, all other nodes watchEnabled=false 3. deployDir is the same as appBase and after I found this post that confirmed these points to me: http://www.mail-archive.com/users@tomcat.apache.org/msg80374.html The problem is the following: let node1 be the master (watchEnabled=true) and node2 the slave (watchEnabled=false) This is my configuration: Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer tempDir=/appserv/tomcat/tomcat60/apache-tomcat-6.0.33/server/clu001node01/temp/ deployDir=/appserv/tomcat/tomcat60/apache-tomcat-6.0.33/server/clu001node01/webapps/ watchDir=/appserv/tomcat/tomcat60/apache-tomcat-6.0.33/server/clu001node01/farm/ watchEnabled=true/ If I copy a war to watchDir of node1 evertything works fine and cluster deploy is achieved. When i restart node1, FarmWarDeployer undeploy my war both from node1 and node2, but re-deploy it only on node1. node1 log: INFO: Cluster wide remove of web app /example Oct 20, 2011 5:50:46 PM org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [/example] Oct 20, 2011 5:50:46 PM org.apache.catalina.startup.HostConfig deployWAR INFO: Deploying web application archive example.war node2 log: INFO: Undeploying context [/example] Oct 20, 2011 5:50:47 PM org.apache.catalina.ha.deploy.FarmWarDeployer messageReceived SEVERE: Application /example in used. touch war file example.war again! Obviously, if I touch my war in my watchDir on node1, tomcat redeploys it correctly on both nodes... but this cannot be the solution... Is it a known problem? Could anyone help me? Many thanks, Marco
JAR locked in Tomcat after using addUrl to dynamically add JAR to running webapp
Hi Tomcat Community:
BACKGROUND:
I have a Servlet-based WEBAPP that is running in Tomcat7, JDK 1.6.0_27 on
Windows Server 2008 R2 64-bit - all 64-bit. We make use of class.newInstance
quite a bit as we have a fairly modular, interface-based system, and create
class instances on the fly. As part of our extensibility, I'm also using a
pretty well documented hack [The code is listed below] for dynamically
adding JAR(s) so they are accessible immediately without stopping our WEBAPP or
the actual Tomcat server process. This process has worked great for both
JAR(s) in the WEB-INF/lib and for ones we dynamically added - until you try and
stop the WEBAPP via the Tomcat manager app.
PROBLEM:
This solution for dynamically loading JARs worked great as long as we
start/stop the actual Tomcat server process, but I found out the JAR(s) that I
have been dynamically loading this way are not released when you stop the
WEBAPP. I am using SysInternals Process Explorer to monitor the open file
handles of the Tomcat7 process. I can see that when I stop the WEBAPP, the
dynamically loaded JAR is still referenced.
QUESTION:
I made an assumption that calling
Thread.currentThread().getContextClassLoader() would provide me the classloader
of my WEBAPP - which should be the same classloader that all the JARs in the
WEB-INF/lib are in. We control the WEBAPP, so I assumed this was a safe
assumption.
The usage of the dynamically loaded JAR(s) is no different than the default
JAR(s) in WEB-INF/lib. None of the WEB-INF/lib JARs are left open when we stop
the WEBAPP - only the JAR(s) that are loaded via the addUrl approach below.
I have been through a number of online articles when I first created this logic
- including a PDF by Ted Neward [while at Developmentor] that described these
approaches, but am not sure how to troubleshoot this further now.
If anyone has an answer or any suggestions, I would greatly appreciate it.
Thanks in advance,
Bob
Code to dynamically load JAR(s):
public static void loadJarOnTheFly(File jarFile) throws IOException
{
Class?[] parameters = new Class[]{URL.class};
// IMPORTANT: MUST use the webapp classloader - so derived extension
classes can resolve their base classes
ClassLoader contextClassLoader =
Thread.currentThread().getContextClassLoader();
// cast to a URL class loader so we can additional JAR(s) to the search
path
URLClassLoader webappClassLoader = (URLClassLoader)contextClassLoader;
Class? sysclass = URLClassLoader.class;
try
{
URL jarUrl = jarFile.toURI().toURL();
Method method = sysclass.getDeclaredMethod(addURL, parameters);
method.setAccessible(true);
method.invoke(webappClassLoader, new Object[]{ jarUrl });
}
catch (Throwable t)
{
throw new IOException(Error, could not add URL to system
classloader);
}
}

ODBC jar files
Question. Will it hurt to have two different odbc jar files in the lib folder? I've been connecting to a production server on Oracle10g for some time, and have had my context.xml file in the META-INF directory of one web app configured to hit this Oracle server. Our group just got a new development server on Oracle11g, and while I can connect to it via Toad or SQL Plus (thereby assuring the tnsnames file is properly configured) I cannot connect at all from the web app in Tomcat. I've been using the drivers in the ojdbc14_g.jar file for some time but I think I may need ojdbc6.jar for the new Oracle server. I wasn't sure if these two would conflict or not. FWIW, I'm using: Tomcat Version 6.0.26 JDK 1.6.0_18 Win XP is my OS for the test machine. The above mentioned .jar files. I just added the second one, ojdbc6.jar, then deleted the work folder contents and restarted the web app. My context.xml file is configured in the following manner: -- Context Resource auth=Container description=changectrlappdev name=jdbc/myoracledev type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver username=usernm password=password url=jdbc:oracle:thin:@croesm6734:2504:LANDMVJ maxIdle=30 maxWait=1 maxActive=10 testOnBorrow=true timeBetweenEvictionRunsMillis=-1 minEvictableIdleTimeMillis=28800 poolPreparedStatements=true removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=false/ Realm className=org.apache.catalina.realm.DataSourceRealm localDataSource=true dataSourceName=jdbc/myoracledev userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/!--using -- /Context I've also tried the following: -- Context Resource auth=Container description=changectrlappdev name=jdbc/myoracledev type=javax.sql.DataSource driverClassName=oracle.jdbc.driver.OracleDriver username=usernm password=password url=jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC )(KEY = LANDMVJ)) (ADDRESS = (PROTOCOL = TCP )(HOST = croesm6734.specserver.net)(PORT = 2504))) (CONNECT_DATA = (SID = OPSDEV) (SERVICE_NAME = LANDMVJ) maxIdle=30 maxWait=1 maxActive=10 testOnBorrow=true timeBetweenEvictionRunsMillis=-1 minEvictableIdleTimeMillis=28800 poolPreparedStatements=true removeAbandoned=true removeAbandonedTimeout=300 logAbandoned=false/ Realm className=org.apache.catalina.realm.DataSourceRealm localDataSource=true dataSourceName=jdbc/myoracledev userTable=users userNameCol=user_name userCredCol=user_pass userRoleTable=user_roles roleNameCol=role_name/ /Context -- with the same error message getting logged.

I really wasn't sure if those two jar files would conflict and cause issues. If anyone can enlighten me on this it would be appreciated!

- NOT installed as a Windows service. Tomcat starts/runs/stops fine
using startup.bat and shutdown.bat
- Applications deploy properly, can be accessed and used properly
- Tomcat admin console can be accessed and used properly
- The problem is that the log files are always empty (0kb)
- The following log files are produced by Tomcat, but are always
empty:

o host-manager.date.log
o localhost.date.log
o manager.date.log
- The following log files are NOT produced by Tomcat (missing)
o stdout.log

- Ive tried several workarounds to produce the log files properly,
all without success
o Tried running the .bat file from the command line directly piping output
to a local .txt file; all that gets piped to the .txt file is the java
environment variables that are being used
o Modified catalina.bat to pipe %EXECJAVA%
%ACTION% commands to log file
(didnt work, nothing in the log file)
o Followed instructions at
http://tomcat.apache.org/tomcat-5.5-doc/logging.html to set up logging
§ Tried log4j; log files didnt contain exception messages
§ Tried commons logging; no change (log files still empty)
o Followed the only previous mail-list item that seemed similar to my
situation: http://www.mail-archive.com/users@tomcat.apache.org/msg74244.html
§ Followed all responses; same result; this thread doesnt seem to be
solved
§ (I do not receive VM instantiation errors like the user in that thread
does)
- I cant upgrade to a newer version of Tomcat because 5.5.33 is
the only version supported by the project Im working on

(You may include ConsoleHandler as well if you want to dup all to the

Use case for adding configurable behavior for unpacking WARs deployed outside the Host's appBase?
We finally tracked down why a 3rd party application we use stopped working as of our upgrade to 7.0.14 (and subsequent) - it was the fix applied to 7.0.12 which stopped unpacking WARs that were deployed from an appBase outside that of the container. It presented itself in an odd way, which is why it took so long to track down (vague and unhelpful RMI connection failure from some spawned RMI server). Digging a bit today I found some history on this issue, which seems to be summarized in this bugzilla report: https://issues.apache.org/bugzilla/show_bug.cgi?id=51294 Here's my use case for why I'd like this behavior to be configurable, either at the app level or the host level (ie, honor either or both of the unpackWAR flags for applications outside of the host's appBase). We have a standardized deployment mechanism. We prefer the model where wars are put in a standard directory (outside of the server's app base) and then referenced by a context file for the instance (instance/conf/engine/host/mycontext.xml). This allows us to manage the WAR files outside of the tomcat instance directory and have the war file names be something other than the context path for the web app (like a filename with version information in it!). We deploy mostly web applications developed in-house. These applications don't care whether they are exploded or not. We also deploy a few 3rd party web applications. One in particular *requires* that it be exploded on disk. The vendor refuses to change the app. Given the current state of things, we will have to modify our deployment approach across the board just to satisfy this one 3rd party application, or have a non-homogenous approach to web application deployment and treat this one in the special manner. Neither approach is appealing (3rd party app forcing a particular deployment model on our operations or heterogeneous deployment model). Would it be possible to have the behavior put back at least as an optional behavior?

RE: ODBC jar files
I had kind of thought that might be the case, but wasn't sure. I had web app A with a context file in its META-INF directory and web app B with a (different) context file in its META-INF directory.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Garey, (Thanks for taking this back onto the list). On 10/19/2011 5:07 PM, Garey Mills wrote: Geoserver only has basic authentication on an object by object level. We are deploying it in a unversity that has a Centralized Authentication Server, or CAS. CAS has a implementation that can be used in tomcat, and that is realized as a set of filters. Do you control anything about the implementation of the CAS filters? The first problem is that filters have the severe limitation of only allowing one asterisk, making it impossible (as far as I can see) to distinguish URLs on the basis of recognizing a pattern in the query string. It's true, filters can only be mapped by relatively simple url-pattern matching constraints. That doesn't mean the the Filter itself can't be smart about how it does it's own checks. There is no prohibition on further processing of the URL to determine how to act. These CAS filters have to be used in situations where the servlet spec's paltry url-pattern mapping semantics must be overcome, right? I'm surprised to hear you say that they are so inflexible. So this seems to necessitate recognizing the pattern in code, modifying the URI in some recognizable way (or setting an attribute on the request) and redirecting so that it gets intercepted by the CAS filter(s). You can set an attribute on the request and then continue the call chain (where the CAS filter is later in the chain): there is no need for a redirect and/or forward to occur. This makes it very difficult to work with Geoserver directly. While the code is available, this is a massive project. On the other hand, I got my scheme to work more or less, but there are problems. I got it to work by instantiating a RequestDispatcher by getNamedDispatcher and finding the servlet name (dispatcher) in Geoserver's web.xml. However, I find that the content that Geoserver returns embeds a number of URLs that point back to itself. I would have to somehow intercept Geoserver's return in my fronting webapp and rewrite those URLs. If this is the strategy you have chosen, then yes, you will have to act as a proxy/reverse proxy. You're going to have to do that in any event. And, it's a total pain in the neck. Better to intercept all the traffic on it's way to Geoserver and do whatever modifications you need to on the fly, there, than to try to proxy everything and rewrite links, etc. If I bite the bullet and attempt to change Geoserver, there is another difficulty. If you can customize Geoserver's behavior by inserting your own filters somewhere in the filter chain (which is trivial of course), then I would highly recommend that route. Dual webapps where one of them does authentication and acts as a re-writing reverse proxy sounds like madness. I am attaching Geoserver's web.xml. Here also are the CAS filters from my fronting webapp: filter filter-nameCAS Single Sign Out Filter/filter-name filter-classorg.jasig.cas.client.session.SingleSignOutFilter/filter-class /filter Hah. I usually see that called SingleSignOn, but I guess if you want to get out of everything quickly, that will help, too. :) A major problem is how to integrate these two. If you can tell me, maybe I can attempt to introduce the necessary changes to the Geoserver servlet. I didn't see the web.xml from Geoserver, but merging web.xml files shouldn't be /too/ hard. If you want to keep Geoserver's webapp relatively untouched (for easier upgrades, etc.) you could use XSLT to process their original and add your own stuff (for instance, installing your own filters at the beginning of the filter chain with all their filters running afterwards). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk6gjYUACgkQ9CaO5/Lv0PBjZQCggQWKntrSt/Ko1tgND8tldEnJ SWMAniNt+FtWZWqG3M+MwybohZ51w3Mr =a9sS -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

If you actually do need native code, make sure the LD_LIBRARY_PATH environment variable or the Java system property java.library.path points to the location of the .so file so the JVM can find it when resolving references to functions in it. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: JAR locked in Tomcat after using addUrl to dynamically add JAR to running webapp
While I can appreciate the desire to never use Windows, that isn't reality in many of the industries that use our product, so running Tomcat on windows can't be considered an oddity or edge case. If it is, we better look for another app server. With regard to finding a solution, I'll try the antiJarLocking setting, but I don't have any problem with any other JARS, so I don't hold out much hope for this fixing my problem. I may look at upgrading to JDK 7 - which has added a close method to the URLClassLoader. Perhaps this might fix it. If anyone else has any other ideas why ONLY JARs added via the addURL hack I've shown below don't get unloaded when the WEBAPP is shutdown - vs stopping Tomcat completely, I would greatly appreciate it.
