Re: Tomcat and webdav in general [Beginner]
Hello again, The thing is that the company wants to implement webdav to it's own existing document and knowledge management system, allowing users to change content without downloading a document and having to upload it back again. I believe the documents are opened from within that management system. So, Mark you are saying that the already existing Tomcat+webdav structure will work for that purpose, where one only needs to mount the root folder of the cms-like-system, like I mentioned earlier? Will user privilleges work too? Does that mean that the server side doesn't need to be touched at all and basically a good client needs to be found that handles locking and etc.? Thanks again for the info!!! Mark Thomas-15 wrote: Sven Braun wrote: I have no knowledge of the CMS being used at all, what I know is that it runs with tomcat.

Tomcat, IIS and Authentication
Hi all! We have an application (hosted with Tomcat) which has to communicate with the .NET world, i.e. our web application is integrated in an Asp.Net application hosted by an IIS. So, to connect both we have an Asp.Net Connector on the one side and a Java Connector on the other side. If the user selects something on our application the JavaConnector is called which creates an URLConnection to a specific Asp.Net site. At the moment, the URLConnection is established with an empty username and password because we created a specific IIS user which is always the same for every request. Now, we want to use the integrated windows authentication, i.e. we want to know which user is currently asking. That's why we thought on NTLM authentication or something like that... But we didn't know how to get the credentials in the Java Connector to establish the connection with Asp.Net. What can we do? Is it generally possible to use the integrated windows authentication in Java with IIS and Tomcat? How? Can you give me some tips? Regards, Jacqueline.

Re: Problems with JAAS-Realm
Hi David,
thanks again for your time!
There is only one instance of your realm that is shared by all incoming
requests. That mean only local values inside methods are individual.
Every property that is stored at instance of class level is to be
accessed and stored in a ThreadSafe manner. It's up to you code to be
Threadsafe by assuming several Http Threads can run it at the same Time.
I am not so shure if I've a clear understanding of the realm architecture. So
let me present my view of it:
Context -- Singleton?
Valve -- Singleton? Valve is the one who passes requests and responses
objects
Realm -- Singleton?
here I get requests and responses objects passing through the
Valve that wrapps the realm. A call of the
request.getRemoteAddr() invokes the valve to get current
request informations, which is out of scope of the current
informations I get about the user in the realm (except
username and password, which are set in the callback handler).
How this is done? Which pattern is used, listener?
You can, however, make the assumption that the Thread that goes inside
your realm methods is the same that will serve your request. As such,
you can save datas for later use by same Thread using ThreadLocal.
Any example?
However, Threadlocal are to be used with caution. Do not forget to set
their value back to null our you could face a case of memory leak.
Ok.
Thanks!

Salut David,
thanks very much for your answer!
public SecurityConstraint[] findSecurityConstraints(Request request,
Context context) {
HttpServletRequest req = request;// catch Request
session = req.getSession(); // catch session
ipAddress = req.getRemoteAddr();
The problem:
In a first try this seems to work. But if more then one client try to
use the authentication, it catches the last IP address of the user who
makes a request and not the IP address of the current client I like to
authenticate:
So, the req.getRemoteAddr() seems to catch the information outside of
the current thread and I don't know why. Have someone an idea?
req.getRemoteAddres() will get the address of that specific request,
it's isolated from other simultaneous request, or lots of people would
start getting problems using it. I would be more enclined to take a look
at where you are defining the session and ipAddress properties, it looks
like they are class or instance level, where it's mandatory that Realm
be ThreadSafe and stateless.
This sounds like as my problem seems to be elsewhere as I supposed. I
have no idea where I should tell tomcat to keep the thread statefull.
I tried to set some page directives on my login.jsp:
%@ session=true % (which I think is standard)
%@ isThreadsafe=false %
This doesn't help. Of course, it can't work, cause the Realm is a
valve and therefore the Realm is the part who calls the login.jsp page
and the directives of the page appears, in manner of speaking, to late.
How can I tell the Realm to get ThreadSafe? Or have I missunderstood
something?

RE: Basic question - Ingterating Tomcat with Apache
From: albrecht andrzejewski [mailto:[EMAIL PROTECTED] I think tomcat stand alone is - easier to deploy. And that's all. There are also fewer things to fail, and a smaller learning curve for your system administrators (if they don't already know Apache httpd and the JK connector). I think apache as a front end is a more flexible and secure solution. - if apache fails, tomcat is not affected ... but is inaccessible. This is a failure mode you don't have with just a Tomcat. - if tomcat fails, apache can redirect request to another tomcat True. How often do you expect this failure mode? - when you serve static content juste like image of your site and all static text part , javascripts, etc ( i mean... dynamic content is often just an hour ticking at the top of the page!) apche can better handle the request and serve them quickier (with cache). There have been a couple of benchmarks on this, most recently by Peter Lin (available at http://tomcat.apache.org/articles/benchmark_summary.pdf). They showed that Tomcat 5.0 and higher are sufficiently efficient at serving static content that you'll saturate your network before you run out of resources on the server. Peter saturated a 100Mbit/s LAN connection. Am i wrong ? As i have currently nothing pre-installed on it... and it would be fine to know what you are thinking about it. You seem to be pro vanilla tomcat... But just let us know WHEN pure tomcat has to be choosen ! Vanilla Tomcat never *has* to be chosen. I like systems with fewer moving parts - they're generally simpler to manage, more robust and easier to debug when they go wrong. And security-wise, I'd much rather put a proper firewall in front of a web server than rely on httpd to catch all the possible attacks! You may have other reasons to add httpd. Unless you have very slow boxes and very fast network connections, speed of serving static content is not a valid reason. I'd never assume httpd is any more secure than Tomcat, so security (to me) is not a valid reason. You may want to put httpd in front, simply so that you can load-balance and scale Tomcats as your application grows - that's a valid reason if you don't want to use a hardware load-balancer, and plenty of folks load-balance that way, including some quite large sites with quite demanding SLAs. Just make sure you know what you're gaining by adding the extra system! - 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]

Re: Tomcat and webdav in general [Beginner]
Alright I got some more information about the cms structure. One doesn't have access to the actual files but to a database (well, I don't). Which is even more confusing. So I was told to find a way to represent that data-tree creating a program that could look at the db-structure to be used with webdav. Do you have any idea how or if this can be achieved? Or is it necessary to actually mount the root directory and not a db? I've installed Slide which works fine but I don't know how to deal with that underlying data structure mentioned above.

Cactus Authentication problem with Tomcat 5.5.20
Hello all, I am having some difficulties to setup cactus tests using tomcat 5.5.20 (Everything works fine with 5.5.20). I am using form authentication in cactus tests (as described on the cactus web site). When I look at the generated request, I get the authentication layer called with all the parameters needed for the test (service name, class,...), but when the request for the actual test is generated it is missing all the parameters to run the test. So I am suspecting something must have change in tomcat (nothing has changed in the cactus environment) in the way the authentication calls are handled in tomcat post 5.5.20 (I have tried 5.5.23 and 5.5.25). If I disable authentication all is working fine again. For the authentication layer we use a JDBC Realm. Outside cactus tests the webapp is working fine in 5.5.25. I would really appreciate if anyone would have an idea where I should look at as I am really having a hard time to understand where these parameters get swallowed.

issue when redirect/forward on not - parsed form/multipart request
Hello, Hopefully this is the right place for my problem. I wrote a servlet (running on Apache Tomcat 5.5) using Commons FileUpload and it works good except for the following problem: If a user wants to upload a file larger then sizeMax, a SizeLimitExceededException is thrown while parsing the request and I want to redirect the user to another webpage displaying a warning/error. If the users session expired the request is ignored (not parsed) and the user is redirected to some page telling him about it. If I try this using Tomcat 5.5 alone (localhost:8080/...) it works well, but if I use it together with Ms IIS / isapi redirector (jk-1.2.25), then those warnings are not shown, instead a (hope this is the right translation) Connection aborted, Connection to server was reset while loading the page is shown in the browser. No errors found in the logs of Tomcat/Redirector. If the request is fully parsed (file upload ok), then all goes OK. Is there something that has to be done (sort of cancelling the request)?

mod_jk JkShmFile directive
Hi I have asked about this directive(JkShmFile) before but on the apache-http list. I am still not 100% clear as to the exact usage of this directive. This page is very vague about usage: http://tomcat.apache.org/connectors-doc/reference/apache.html After a lot of googling and searching through my mail archives I found the following snippets of information: start of snippets Concerning mod_jk there is no hard upper limit. If the number of workers (counting all lb workers and all members of lb workers comes close to 64, you will need to increase the JkShmSize.) No dependency on the tomcat or AJP version. I didn't think about old JK versions though. 1.2.23 doesn't count as old. I am not intending to use shared memory or load balancing or anything like that. Therefore, I have no such configuration in my jk_workers.properties file. Could this be the reason why there appear to be no maps when trying to match JkMounts? Are the workers being configured and then discarded because there's no place to put them in memory? That would suck, but at least make sense. Should not be related. Nevertheless even without load balancing, using a single member load balancer and shared memory can be interesting because of the advanced managment and information features provided by the stu worker (that uses the shared memory to comunicate with the lb). The reason why it ended up in /var/log/httpd/jk.shm is because the JkShmFile logs/jk.shm directive in the httpd.conf translates to $ServerRoot/logs/jk.shm where $ServerRoot in this case is /etc/httpd. /etc/httpd/logs is a symlink to /var/log/httpd. It is used as a scoreboard with run time data for workers so the load balancer works more accurately. More logical placement for /var/run/mod_jk This file is used for shared memory, lock, ...of mod_jk threads. if you don't declare it in your mod_jk config file, mod_jk will create a default one in your http log directory. /end of snippets My questions Is this shared memory used by different child apache processes on the same machine or is it a bit more involved than that. If the answer to the above question is yes, do you really need this in the config. What value does it add to have this directive available, except for the fact that you can specify the location... I would also kind of expect the JkShmSize directive to be automatic instead of having to specify it. If it needs to be bigger than the default 64Kb it should grow on its own accord.

Re: mod_jk JkShmFile directive
[EMAIL PROTECTED] wrote: My questions Is this shared memory used by different child apache processes on the same machine or is it a bit more involved than that. Yes, its simply that. The shared memory contains configuration and runtime information for load balancer workers and their members. We need it in order that - all apache children share the same status information for load balancing members (OK, ERROR, ...). Before shm, each child had to detect an error by itself (possibly burning requests etc.) - share the information about load taken by the individual workers. Before shm, each child had its own load counter, leading to very bad balancing behaviour under small load - share the information for the parts of the configuration, which are changeable during runtime by the status worker The shm is used by balancer and status workers. If the answer to the above question is yes, do you really need this in the config. What value does it add to have this directive available, except for the fact that you can specify the location... No other value. I think this value is enough. You usually want to place this file in a run directory, where e.g. the pid files go etc. Also the file should not be on NFS (I guess), so hard coding SERVERROOT/logs is not enough. I would also kind of expect the JkShmSize directive to be automatic instead of having to specify it. If it needs to be bigger than the default 64Kb it should grow on its own accord. Yes, that would be nice. Unfortunately this requires a little code surgery and not only a small patch, because at the moment the shm is statically acquired (fixed size) and we need it before we parse the worker configuration, so beforee we know, how many workers we have. To fix that, we would either need to count the workers in a separate pass in advance, or enhance the shm handling to allow growth of it. At the moment we initialize the shm for 64 workers, which on some platforms lead to 28800 Bytes size. Actually I'm not sure, if we will really be able to use 64 workers, or if the number is slightly smaller (63?), because we might need to subtract some offset size used as a header.

As I understand you, you can easily reproduce the behaviour without actually uploading huge files, because the redirect should happen before the actual upload starts?

Uninstall options for tomcat 4.1.31
Hi, I haven't been able to find the answer to this in the MARC archives or elsewhere. Where can I find a list of command line flags for the uninstaller (uninst-tomcat4.exe)? Our product includes tomcat 4.1.31. I would like to silently uninstall tomcat 4.1 before upgrading our users to tomcat 5.5. When running the tomcat 4.1 uninstaller manually, the UI prompts me to remove the tomcat directory and all files in it. Is this option also available via a command line switch? Thanks, Eric - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat 5.5.25 takes 5 minutes to shut down.
Hello! I'm running Tomcat 5.5.25 on SLED 10. I performed the installation of Tomcat manually, using the apache-tomcat-5.5.25 archive from Apache's website. Tomcat will start fine and operate as expected, but shutting down is unreliable and often takes about 5 minutes to complete. If I run the $CATALINA_BASE/bin/shutdown.sh script, it will return immediately without errors, but checking for the process (ps aux | grep tomcat) shows it is still loaded for a long amount of time after the script is called. On a different server with identical hardware and very similar tomcat installation, the shutdown script will bring Tomcat down in about 3 seconds.

Re: Tomcat maxThreads
Hi Filip, The reason I want to use more threads is because of the nature of our AJAX client.

AJP Flush Packet causing text/plain output
We recently switched our development JBOSS instance from 4.05GA to 4.21GA, where we are have been using mod_jk for connecting an Apache front end server (2.2) to the Tomcat AppServer. We have noticed periodic times when the apache web server will return data with a content-type of plain/text (the server default) instead of the real content-type, and a chunked encoding (even if the AppServer was producing a non-chunked content). We tried switch to mod_proxy_ajp, but got the same result. A bit of sleuthing (2 days X 2 engineers) revealed that the AJP connection on Tomcat is sending a SEND_BODY_CHUNK (which I assume is a flush packet) periodically that seem to be confusing mod_jk. We can see in the mod_jk and mod_proxy_ajp debug log that the correct headers are coming from the Tomcat server. However, it seems like mod_jk and mod_proxy_ajp are losing all the header information regarding the packet (including the Powered by headers, content-type, content-length, cookies, etc.). In normal operation, for a sample small transaction, we would see this sequence in response: SEND_HEADERS SEND_BODY_CHUNK END_RESPONSE When the output would come out as text/plain, we would see this sequence: SEND_BODY_CHUNK SEND_HEADERS SEND_BODY_CHUNK END_RESPONSE Is there something we should have configured differently so that mod_jk or mod_proxy_ajp will behave better?

Vmware and Tomcat 5.x 6.x
Hi, I am fairly new to this user group. I have deployed Tomcat 5.0 and Tomcat6.0 on our Virtualized environment; consist of ESX 3.0 servers with Clarion storage. This is first ever deployment of our product on virtual environment and we are facing lots of issues of slowness. There are too many variables to monitor and looking for some path to follow. Previously, I have deployed tomcat in our physical server environment and it's running absolutely fine with all performance tunning in place but same is not working in virtual environment. I was hoping to get some input as if anyone is aware of such issue of vmware and tomcat. Please let me know if you need any further details about components used in our deployment or any details pertinent to this issue. Thank you in advance. Mitesh

RE: Vmware and Tomcat 5.x 6.x
Thanks Chris for reply. Clarion is SAN, so all are data and OS partitions are on SAN. Whole server works fine but our application works using tomcat and I have installed around 20 instances of tomcats on one virtual machine (2.66GHz and 4GB RAM). On similar line, does JDK takes advantage of two CPU compared to one CPU? I can reconfigure Swap file on separate disks than OS disk and see if it performs better.

You didn't say what JDK version you are using, but unless you have something that is seriously out of date, the JDK will use as many CPUs as you have available to the VM.

Try running a single instance to see how it works out. If that is reasonably fast, then try adding more instances until it starts to suck. Then, check your swap file usage and I'll bet you'll see that at some point, you start to heavily swap. You're not seeing Tomcat hosing... you're seeing your OS thrashing. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG+GgH9CaO5/Lv0PARAuAWAJ98MOnNnZzJay8SwaG8ieSjmCrDAACgrS1S qVirHsVVczlbKe6GVKpoZ7Y= =I6VL -END PGP SIGNATURE- - 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: Tomcat and webdav in general [Beginner]
Sven Braun wrote: Alright I got some more information about the cms structure. One doesn't have access to the actual files but to a database (well, I don't). Which is even more confusing. So I was told to find a way to represent that data-tree creating a program that could look at the db-structure to be used with webdav. Do you have any idea how or if this can be achieved? Or is it necessary to actually mount the root directory and not a db? I've installed Slide which works fine but I don't know how to deal with that underlying data structure mentioned above. Caveat: I know next to nothing about slide... Slide is probably the way to go. I think you will need to implement the various store interfaces to make your data accessible via Slide. You might have better luck on the Slide users list although I am not sure how active that list is.

Re: Vmware and Tomcat 5.x 6.x
Mitesh, The most important thing with regards to the JVM, is available memory. Of extra importance in this case is the amount of memory (REAL/PHYSICAL) allocated to the Virtual Environment (VMWare). That said, you also need to determine the Memory Heap usage of each of the JVM instances. Sluggishness usually indicates a memory shortage. At that point SWAP consumption increases. As you would image disk swap would be much slower than real memory. Besides sluggishness, SWAP usage may increase the chance of disk failure because essentially you are using a 100% of resources. In short compare the total Memory Heaps of all the JVMS to the total memory allocated to the Virtual Environment of the VMWare instance. Mitesh Shah wrote: Thanks Chris for reply. Clarion is SAN, so all are data and OS partitions are on SAN. Whole server works fine but our application works using tomcat and I have installed around 20 instances of tomcats on one virtual machine (2.66GHz and 4GB RAM). On similar line, does JDK takes advantage of two CPU compared to one CPU? I can reconfigure Swap file on separate disks than OS disk and see if it performs better.

I was hoping to get some input as if anyone is aware of such issue of vmware and tomcat. AFAIK, there are no Tomcat-specific vmware issues. However, there could be some problems with the JVM in general that you might be coming across. For instance, if you are using a source of randomness that blocks when used through the virtual environment, that might cause a problem. Also, if you are using non-native disks (meaning a big file on the host OS that holds the entire filesystem for the VM), you may experience some slowdown, there.

Tomcat 6 JBoss 4.2.1
Hi All, Is there any recent (in the last year) Tomcat to JBoss EJB examples anywhere? I see old examples that mention using a jndi.properties file and others that indicate a config.xml and others a server.xml. Very confusing but there must be more recent examples. I am trying to use Tomcat 6.0.14 to communicate with EJB's in a JBoss 4.2.1 container. Thanks for any help. -Tony Got a little couch potato?

Re: tomcat5.1 out of memory for swap space not released!
Tomcat 5.0.x has some memory leaks but as far as I recall they were mostly related to context reload. If you are reloading your app, I'd suggst an upgrade to the latest 5.5.x. If you are not reloading, then your app probably has a memory leak. I'd suggest using a profiler such as YourKit to try and track it down.

AW: Tomcat, IIS and Authentication
Hi! Actually, I want it to work the other way round, i.e. we don't have a java application login page because the user is authenticated via the .Net application (- via IIS and integrated windows authentication). We integrated our java application to that windows (Asp.Net) application. If the user saves something on our page f.ex., we call an Asp.Net site for that we need the username / password for IIS. But we didn't know how to retrieve those information on java side. What we tried was the NTLM filter for Tomcat which seems to authenticate, but how can we establish an URLConnection to IIS with the right credentials: |---| |-| |-| | Java| Request| Java | URL Connection | Asp.Net | authenticate IIS |Application| |Connector| Problem: How to |Connector| |---| |-| get credentials?|-| --retrieve infos - WebService | | | |---| |- | Tomcat | |---| It's getting clearer now :-/ ? -Ursprüngliche Nachricht- Von: Gabe Wong [mailto:[EMAIL PROTECTED] Gesendet: Montag, 24.

Preuss, Jacqueline - ENCOWAY wrote: Hi all! We have an application (hosted with Tomcat) which has to communicate with the .NET world, i.e. our web application is integrated in an Asp.Net application hosted by an IIS. So, to connect both we have an Asp.Net Connector on the one side and a Java Connector on the other side. If the user selects something on our application the JavaConnector is called which creates an URLConnection to a specific Asp.Net site. At the moment, the URLConnection is established with an empty username and password because we created a specific IIS user which is always the same for every request. Now, we want to use the integrated windows authentication, i.e. we want to know which user is currently asking. That's why we thought on NTLM authentication or something like that... But we didn't know how to get the credentials in the Java Connector to establish the connection with Asp.Net. What can we do? Is it generally possible to use the integrated windows authentication in Java with IIS and Tomcat? How? Can you give me some tips?
