Re: Tomcat not sending JSESSIONID (servlet session cookie) with new sessions
Have you set cookies="false" in the app's declaration? That'd do it. What happens if you put a trivial test.jsp in webapps/ROOT and request http://www.yourserver.com/test.jsp? By default a JSP will create a session and you should get a JSESSIONID cookie. -- Len On Tue, Apr 22, 2008 at 7:28 PM, Timothy Washington <[EMAIL PROTECTED]> wrote: > Hello there - newbie question.

Tomcat not sending JSESSIONID (servlet session cookie) with new sessions
Hello there - newbie question. I'm developing a browser-based application. I i) copy the war file to the webapps/ directory, ii) startup tomcat and iii) send an http request from Firefox. In my handling servlet, if a session doesn't exist for this client, then I create one (via request.getSession(true)). I expect that cookie (and by extension the session) to still be there on the next request. However, tomcat's HTTP response to the first request does not include the JSESSIONID cookie. So effectively my application is still only request scoped (tomcat is creating a new session with each request). How can I get tomcat ( I've tried tomcat-5.5.25 and tomcat-6.0.16 ) to reliably send the JSESSIONID cookie when a new session has been created? I turned on Tomcat 6's RequestDumperValve, and got debugging info that indicates that the JSESSIONID is being generated in the response. However, when my browser receives the response, the cookie isn't there.

How to figure out if a user is authenticated when using single sign on?
I recently attempted to upgrade our sites from tomcat 5.5.17, and at some point the behavior of request.getUserPrincipal() changed so it now returns null for all URLs except those declared to require authentication. (Actually, it seems like the behavior was changed long before 5.5.17, but regressed then was fixed again). That completely sucks and seems completely contrary to what the servlet javadoc implies, but whatever, deal with it or write my own container, I guess. The standard workaround mentioned is to place user information in session, but that won't work across webapps using Single Sign On. I have a bunch of webapps, only one of which is protected and requires login, the rest work fine without logging in, but display different information when the user is logged in. This worked great when getUserPrincipal returned a Principal on every URL after login, but I can't figure out any way to do it now. I can just pass the userid around in every URL, but that seems... not good... and involves changing a lot of links. Is there any way of seeing if a user has been authenticated (and get their username) that works across webapps? - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Question on concurrent request to the same servlet
Dikan Xing wrote: When two (almost) concurrent requests to the SAME servlet occurs (for example,I type the same url in two individual browser window), I find that Tomcat seems not to work on the second request until the first is done. Are the two browser windows truly individual, or could they be part of the same browser process? It seems that browsers may constrain themselves in several ways when accessing a single resource (server, URL). However, in my situtaion, my servlet should wait for some other resources to respond. Those resources are quick-responded, but transimssion of requests to & responses from those resources cost much time. Therefore, if the servlet could be run (service method be called) immediately instead of the previous is done, the total response time could be reduced. Then you should, as Christopher mentioned, check that the contention is not caused by those other resources (either via some pooling/synchronization mechanism within your app only letting one request at a time to touch the external resource, or somehow the external resource itself being able to only service a single request at a given time). Is there any option in Tomcat so that I can configurate it to call the same servlet service method (doGet, doPost) simultanously instead of one by one? No options needed -- not even if you're using SingleThreadModel in your servlet. I just wrote a small test and ran it in Tomcat 6.0.14 (not current, but that's what I happened to have at hand); I wrote two servlets, with request body essentially "Thread.sleep(5000)", followed by a printout identifying the servlet (class and instance). One of the servlets was a regular servlet, another was a servlet implementing SingleThreadModel. Then I wrote a test program; a Java command-line application to spawn five threads for making requests to the regular servlet (MTServlet, as in multi-threaded), and another five threads for making requests to the servlet implementing SingleThreadModel (STServlet). Below is output from a run of the test program against a server hosting these two servlets: Start: Tue Apr 22 21:56:28 EEST 2008 Hello from STServlet instance 3 Hello from MTServlet instance 1 Hello from MTServlet instance 1 Hello from STServlet instance 2 Hello from MTServlet instance 1 Hello from MTServlet instance 1 Hello from MTServlet instance 1 Hello from STServlet instance 5 Hello from STServlet instance 4 Hello from STServlet instance 6 Stop: Tue Apr 22 21:56:34 EEST 2008 So, all servlets finished within six seconds of starting the first one -- even those implementing the SingleThreadModel. It should also be noted that all MTServlet calls are handled by a single MTServlet instance (in parallel), but with STServlet the parallelism comes from Tomcat creating several instances of the servlet (as allowed by the Servlet Specification for servlets implementing the SingleThreadModel). I've seen something like you describe, and it was when someone had either declared the doGet() method (or another method called within doGet()) as synchronized, or had written a synchronized code block referring to some single object for all requests. -- ..Juha - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Totally weird. We already discussed that, back at the beginning of this thread. It's due to the object being read in not being serializable now. It's not quite clear, however, how the thing got written out in the first place. > I wonder if you have a class that implements its own read/write > methods that calls the wrong method (read calls write or similar). No, it's because the webapp has stored the session object (actually the facade) into the session - for no apparent reason. The facade is not serializable, of course. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Of course, this will use a few more resources on the DB server, but that's not likely to be limiting.

These changes will be made by customers themselves or professional services. We provide a tag library that exposes all of the functionality of our web application. We use this tag library to build the default skin of the app but customers often want to tweak the appearance in ways that go beyond simple CSS changes. In addition, right now there is no way for them to localize their changes to a particular skin. If they make changes to a presentation tag (or JSP) then all other skins see those changes. And one of my primary goals is to allow users to create custom skins without any configuration changes to the web container. Just drop in the skin and it works. I'm currently exploring ways to work around the problem within the confines of what JSPs allow.

64-Bit isapi
I figured out how to get the isapi_redirect.dll to work on 64-bit windows systems. The key to this was once the correct source code was downloaded from Jakarta, it had to be compiled using Visual Studios 2008 C++ build environment. This is (in my experience) a very finicky *.dll that had to be compiled on the server that was hosting it, or else release" version would not load. I also found that the "debug" version is more likely to load on a similar the "Proc_build". -- Sincerely, Ardo S. Panian H: 508-969-9935 M: 781-771-6728 F: 484-771-6726
Re: Bending Jasper to My Will
Andy I've followed this thread with a some interest because it ties up with some things I've done in the past. I think you are trying to use a technology in an inappropriate way to solve the wrong problem. Correct me if I am wrong but you want to have a level of configuration which is more than just appearance. You want to: 1. be able to add/remove features from a particular page 2. be able to reorder features Is that correct? The next thing which isn't clear to me is at who will choose the feature set. Is this going to be a runtime thing or a startup configuration thing? Will your end-users be able to configure things or will it be the result of specific programming work?

If it was on a virtual server, I'd have suggested that another virtual server on the same host might have been hogging resources - but that's not an option. My next suggestion is to look for the gross cause of the slowdown. Performance Monitor (on Windows) or top / vmstat (on UNIX) and see whether you're short of memory, CPU or disk bandwidth when the system goes slow. If one of those is the problem, the next step is to narrow down which process is the memory, CPU or I/O hog and find out why it only happens at weekends. If you're not short of any of those, the next step would probably be to look at your database server and try to work out whether that's somehow causing the slowdown. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Security with WebLogic (JAASRealm)
Hello I am trying to use a JAASRealm for authentication. I have set up the Realm and it is authenticating with a WebLogic instance and returns a user back (WLSUserImpl) with their groups (if any WLSGroupImpl). I have a custom verison of the WebLogic provided UsernamePasswordLoginModule which doesnt pass in a URLCallback! I now want to look up an EJB on the remote WebLogic server within a servlet, this works too but if I call a secured method (requirings you to have a Group) I get a security error. User cannot.. I have managed to get the Subject from the HTTPSession and then with that call weblogic.security.Security.runAs( subject, new MyEJBLookUpAndCallAction() ); I have the weblogic.jar in the tomcat classpath, and this works fine. Is there away to make is cleaner and just be able to look up the ejb and call it with out having to do the run as? For some reason Tomcat is not assoicating the Subject with the thread. Also: I have debugged the login module and a Subject is created correctly - with WLSUserImpl and WLSGroupImpl, but the Subject I get back from the HTTPSession only has the user in it with no groups. Any help is appreciated.

Tomcat 6 DIGEST auth
I've read this doc: http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html#Digested%20Passwords But I cannot get it to authenticate. I'm putting the digested password for myusers into tomcat-users.xml as directed. One problem is that it's not at all clear what the realm is-- Is the realm the specified in the in web.xml? (eg "Tomcat Manager Application") Or something else? The docs (link above) suggest "localhost:80" might be the realm, but that makes no sense to me, as this would tie it to a specific port. BASIC Tomcat Manager Application The book I have -- "Tomcat, The Definitive Guide, 2nd Edition" is in conflict with the above documentation, making no mention of digesting with the username and realm. The book suggest doing: bin/digest.sh -a MD5 user-password But the tomcat 6 docs referenced above suggest doing: bin/digest.sh -a MD5 username:realm-name:password --obviously very different approaches!

I downloaded and installed Apache 2.2, Tomcat 6.0, and J2SE 1.5 (Becuase j2se 1.6 was buggy and giving problems). When initially configuring the server, I included the following lines in the Apache HTTPD.conf file: LoadModule jk_module modules/mod_jk-1.2.26-httpd-2.2.4.so Apache 2.2 comes with mod_proxy as default. Either way, you must also configure apache to use either mod_jk or mod_proxy. You are trying to do this by using the 'auto config' mechanism in tomcat. and in Tomcat I included: and I personally have never used this and in the installations which I have with Apache 2.2. I use mod_proxy so others may be able to help you more here, but I still think that your problem is that your attempt to service static documents with apache is overlapping with your attempts to serve dynamic information from tomcat. Have you checked that the workers.properties file is being created correctly? What does it have in it? You have explicitly set forwardAll to false, which is OK, but it also means that you must configure apache NOT to look at the same folders that you are using for tomcat. See the comment about noRoot and forwardAll in the javadocs. "Warning: When false, some configuration in the web.xml may not be duplicated in Apache. Review the mod_jk conf file to see what configuration is actually being set in Apache." It would help if you could give us your folder layout and how you expect that to map to your url structure. Basing most of the tutorials I have read about setting up this type of servers, I thought this steps were sufficient to enable the server to work in the above descirbed way. It appears, however, that I am missing something... Trouble with tutorials is that they are mainly created by people in their spare time and they can't possibly cover every variation and condition in a world where individual components of a project are released on their own timescales and to meet their own objectives.

If all you're using httpd for is to serve static content, you're wasting your time and creating much more complexity than you need. Current Tomcat versions don't need assistance for serving static content, other than for heavy SSL traffic; in that case, use the APR connector and OpenSSL - still much simpler than adding httpd to the mix. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

If I were you, I'd start by submitting a bugzilla enhancement and patch
to achieve #1 above (a way to specify the class name for the request
class). Right now, each connector has "new Request()" hard-coded into
its constructor. This won't be an easy task, as you will have to either
modify the arguments to the connector's constructor (yuck), add a static
class field to specify the Request class to use (and break convention
within the Tomcat code), and in either case you'll have to modify every
connector implementation (or, at least the ones you are currently using)
/and/ any code that interacts with the connectors (because of the new
constructor args, new static field, whatever).
Trust me. Use a Valve even if you don't want to use a wrapper as I
suggest. Otherwise, you have to modify Tomcat code for each release,
which is horribly unmaintainable.

Re: Share session cookie across subdomains
That's what I was afraid of - that Request class is huge (2600+ lines) and has lots of fields (50+) some of which are private. So if I create a Request subclass that accepts another Request in the constructor, there are 2 options: 1) initialize as many of the superclass's fields of the new instance as possible using values from the passed-in Request 2) wrap the passed-in Request & delegate method calls to it (100+ methods) #1 is very error-prone, as many of the set methods in Request do things other than just setting the instance variable to a new value and in a future release when Request inevitably changes it will be broken. #2 is also not a good idea: my new Request subclass is not a true wrapper/adapter since I'm overriding one of the methods to get my desired behavior (configureSessionCookie). That method is not called directly, rather is a protected method called by a public method so I have to pick-and-choose which methods get delegated and which don't, which results in state split across two Request objects which gets very confusing and is also very error-prone. Overall, I'm going to call the Request API unsuitable for extension and in particular, I'm going to say overriding configureCookieSession in a Request subclass is not a viable solution to the cross-subdomain session cookie problem. To make Request suitable for extension I can see 2 possible solutions: 1) Provide a way to specify the fully-qualified name of my Request subclass in server.xml so Tomcat instantiates that instead of org.apache.catalina.connector.Request 2) Provide a copy constructor in org.apache.catalina.connector.Request that initializes its state based on the state of the passed-in Request If I'm missing something, please correct me.

JMXProxy
Hi everyone, I want monitoring Tomcat applications below webapps. So I am using JMX for to do this. Exactly I am interested in the timing for every process, so I am using this http://localhost:port/manager/jmxproxy/?query=RequestProcessor for extract what I want, I am monitoring /processingTime, /but I dont know which one, I mean that there are several /processingTime /for the same application.

Tomcat context.xml and classpath
Hi to all, I'm currently working on a project that uses a specific oracle driver version put in common/lib and it cannot be changed at the moment. The problem is that i have to deploy another application on production server which datasource (defined in META-INF/context.xml) doesn't fit very well with drivers mentioned before. My question is if it's possible to force a resource to load a jar from a specific path and avoid conflicts.

Sounds like your application is not correctly releasing some operating system resource, so the JVM is keeping hold of the resource. This would cause memory to be reserved outside the Java heap but inside the process. Good candidates are: files, threads (which have both a Java stack and a host stack, and it might be the host stack not being released), almost anything JNI. I've no doubt there are other possibilities as well! Can you monitor the system calls made by the application over a period of time, looking for systematic mismatches between resources that are opened and resources that are closed? I'm not sure which variant of UNIX you're running, but most have some way of monitoring a process' system calls. If you have the /proc filesystem on your system, looking through /proc for your process may also help. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
