Tomcat 4.1 not starting, how do I track error (database pooling)
Hi having written an application that ran fine on Tomcat 5 I am having to regress it to run on Tomcat 4.1 running on Windows. part of the deployment involves setting up database pooling. First of all I deployed my application war only and started Tomcat using catalina start this worked ok, but I then needed to configure database pooling to get it fully working. In Tomcat 5.0 I had a config file /contextname.xml /under CATLINA_HOME/conf/catalina/localhost which worked fine, under Tomcat 4.0 I have added the contents to server.xml. I then ran catalina.bat start this starts another window but then disappears immediately before I am able to trap the problem, there is nothing in the log file to indicate the problem. Could anybody please help with any of the following ? 1. How do I stop the window started my Catalina from disappearing so I can see what the problem is. 2. In Tomcat 4.0 can I have a config file for my application rather than adding it to server.xml 3. I am using the mysqllConnectector 3.15 driver does this work with Tomcat 4.0. 4. Are pooling connections configured the same in 4 as 5 or not below I have listed the contents of my xml file from Tomcat 5.

Address already in use:JVM_BIND:8080
When I try running Tomcat from the DOS prompt by typing 'tomcat start', I see the SEVERE Error message: Address already in use:JVM_BIND:8080. I know I am running IIS on port 80, but I want to keep the same port it runs on, and manually start Tomcat when I need it. Why can't I get it to work?

RE: Address already in use:JVM_BIND:8080
this means you are running other software on Tomcat's default port 8080. This may either be another tomcat? or some other process. Load a command prompt and type netstat -an this will show you if anything is listening on 8080. There is also a tool http://www.sysinternals.com/ntw2k/freeware/procexp.shtml that may help you find out what is listening on port 8080. it will not be IIS unless you have setup another site with 8080. If after all this you cannot find out what is binding 8080, edit server.xml in tomcat/conf and change 8080 to 9090.

RE: Address already in use:JVM_BIND:8080
the address already in use error indicates that the port is already in use by another service (probably IIS from what you've said). you can't have two services on the same port. stop IIS and check that IIS does not still have hold of port 8080. use netstat -a at the dos prompt to check. -Original Message- From: Harry Douglass, Jr. [mailto:[EMAIL PROTECTED] Sent: Thursday 04 November 2004 02:04 To: [EMAIL PROTECTED] Subject: Address already in use:JVM_BIND:8080 Hello, I am trying to install Apache Tomcat to run JSP and servlets for the first time.

RE: Huge tomcat memory footprint
Hi, If there is a memory leak in our application, tomcat or java, what are the symptoms I should look for. Will the heap usage (shown by visual GC, optimizeit etc) keep growing and eventually reach the max limit set using -Xmx option to java? Yes, the heap will keep growing and eventually reach the max, at which point you will get OutOfMemoryErrors and hung/unstable behavior. However, if your leak is small, it might take a very long time before this situation is reached. Run your app inside a profiler, conduct some operations typical to your app, and then look at the heap. Most profilers now have features that show you object reference trees, i.e. what objects are holding onto what references. If you see stuff still in memory that you think shouldn't be there, fix it.

Can I configure a webapp that is stored on something other than filestore?
I'm working on a virtual learning environment. It's essentially one huge webapp. We don't want to manage files on the physical filestore; instead, we want to use our own virtual filestore, for reasons too zany to go into. Is there a way of setting eg. an appBase or a docBase so that it points, not to filestore, but to a URI? If so, we can add an appropriate handler to the URIs so that we manage vfs:... and everything Just Works. Failing that, is there another appropriate mechanism for intercepting filestore access from Tomcat and redirecting it to our own code? A bit of an open question, I know. The Tomcat 4 documentation appears to indicate that a Host's appBase is a URL but, on trying it with 5.0.28, file: URLs are not recognised, let alone anything more outlandish.

Re: Tomcat 4.1 not starting, how do I track error (database pooling)
Thanks very much all working, the problem was I had removed docbase paramter not hinking it was needed because the code was hosted directly under webapps. BTW username is correct in TC4. My context is privileged just because I copied it from somehwere else without knowing what it meant, no good reason. Shapira, Yoav wrote: Hi, 1.

RE: Can I configure a webapp that is stored on something other than filestore?
I believe that if your servlet is /mywebapp/myServlet and your user accesses /mywebapp/myServlet/iwant/this/file, the iwant/this/file part is available as the request parameter getPathInfo() and you can do what you like with that - access a database, access any filesystem to which you have access, redirect to another URI, etc. So all you need to do is write a simple servlet that maps their request to whatever resource you want to map it to. This could include a simple redirect to another URI. Never used this myself but have noticed it in the docs. -Original Message- From: Peter Crowther [mailto:[EMAIL PROTECTED] Sent: Thursday 04 November 2004 13:11 To: [EMAIL PROTECTED] Subject: Can I configure a webapp that is stored on something other than filestore?

RE: Can I configure a webapp that is stored on something other than filestore?
From: Steve Kirk [mailto:[EMAIL PROTECTED] I believe that if your servlet is /mywebapp/myServlet and your user accesses /mywebapp/myServlet/iwant/this/file, the iwant/this/file part is available as the request parameter getPathInfo() and you can do what you like with that - access a database, access any filesystem to which you have access, redirect to another URI, etc. I can well believe this, yes. Problem is that I *think* I want it to happen at a lower level than this - I want to fool Jasper and, in fact, the rest of Tomcat into compiling and executing a JSP that has been accessed via our virtual filesystem. That JSP may, in turn, access further files within its webapp that we want to be accessed via the same virtual filesystem. To make life even more interesting, we want to be able to drop JSPs etc from unmodified webapp into this environment and have them Just Work. So all you need to do is write a simple servlet that maps their request to whatever resource you want to map it to. Just to get this straight... can I write a servlet that dynamically takes a request and re-maps the target? I'd expected to be able to do that with a valve, but hadn't expected to do so with a servlet. A pointer to the appropriate docs would be much appreciated!

I'd expected to be able to do that with a valve, but hadn't expected to do so with a servlet. A pointer to the appropriate docs would be much appreciated! Steve probably had a Filter in mind, not a regular Servlet. While higher in portability (but further down the execution pipeline) than a Servlet, a Filter can be used to redirect requests and responses as needed. A Valve is very similar to a Filter conceptually, but is Tomcat-specific. In fact Valves were around before Filters, and are now for the most part not strictly necessary. However, I think your requirements cannot be met by the current Tomcat codebase without substantial modifications. You'd need *at least* a custom Host (to not use the work directory filestore), a custom Jasper (for the same purpose), a custom ApplicationDispatcher, a custom Context, and possibly other components.

Re: mod_jk2 - problem with servlets
Nevermind I figured it out. Just needed to add this in the Host in conf/server.xml: Context path= docBase= debug=1/ Doesn't make a lot of sense but it did the trick. John Hello Im running tomcat5 with mod_jk2, apache 2 and RH FC01 Im having trouble getting servlets to work under mod_jk2 and shared instance for virtual hosting. It works fine with preview link context for the site: http://ip:8080/domain.com/serlvet/helloworld but with domain.com/servlet/helloworld does not work. I uploaded the root contents for servlets-examples to the root of the site (html folder which is also doc base). The WEB-INF in the dir is from the servlets-examples.

RE: sessionS info persistence when restart Tomcat
Hi, Tomcat persists and reloads sessions on restart by default. And the default session timeout is 30 minutes. So you shouldn't have to do anything.

RE: Can I configure a webapp that is stored on something other than filestore?
From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Steve probably had a Filter in mind, not a regular Servlet. While higher in portability (but further down the execution pipeline) than a Servlet, a Filter can be used to redirect requests and responses as needed. A Valve is very similar to a Filter conceptually, but is Tomcat-specific. In fact Valves were around before Filters, and are now for the most part not strictly necessary. Thanks for that piece of information - we'll look at using filters rather than valves. However, I think your requirements cannot be met by the current Tomcat codebase without substantial modifications. You'd need *at least* a custom Host (to not use the work directory filestore), a custom Jasper (for the same purpose), a custom ApplicationDispatcher, a custom Context, and possibly other components. As you said in your original post, zany ;) Indeed. OK, I'll work on other ways to do this.

RE: sessionS info persistence when restart Tomcat
I had always thought all sessions were lost when the server restarts. In fact I just tried it and confirmed that (5.0.28). Are we maybe talking about 2 different things? I have nonstandard config (a very sparse server.xml, no explicit Manager configured in server/web/context xml), and I do not use TC authentication/realms, I just use request.getSession(true) and rely on cookies to track users. After a restart, the webapp has lost track of users that were tracked right up to the restart. Is this the manager config ref you were talking about? http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/manager.html I just read through it. If I've understood correctly, because my Manager is not explicitly configured, I have a default session manager implicitly. I stopped the server and looked for the serialised session file under /work but just found the usual .java and .class files and one file called tldCache.ser, no sessions.ser or anything that looks like a serialised session file. -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday 04 November 2004 15:07 To: Tomcat Users List Subject: RE: sessionS info persistence when restart Tomcat Hi, Tomcat persists and reloads sessions on restart by default.

Tomcat fails - Can't read body, waited #0 Seems size related (SOLVED)
Whatever it was, it doesn't do it in 4.1.31. Regards Roger -Original Message- From: Varley, Roger Sent: 29 October 2004 11:32 To: [EMAIL PROTECTED] Subject: Tomcat fails - Can't read body, waited #0 Seems size related I have a servlet that recieves data from a client. All the servlet is doing is reading from the InputStream of the HttpServletResponse (BufferedReader br = new BufferedReader( new InputStreamReader(request.getInputStream()));) and writing the data to a disk file. Periodically Tomcat refuses to read the data and dumps with an IOException (attached below). I've googled for the error message but all I can find is references to CVS versions of the AJP13 code - which puts me out of my depth. I can't find any reference to the error message in the list archives. The odd thing is this seems to be related to the size of the data stream. The data is actually an Order Confirmation and when the order contains five lines at 7745 bytes everything works OK. When the order contains 6 lines (or more) at 8862 bytes then I get the dump. It's not related to the data content - I've tested this by using known good data. I'm using Tomcat 4.1.7-LE-jdk14 - upgrading is an option, but not one I will be able to undertake lightly.

Hi, I had always thought all sessions were lost when the server restarts. In fact I just tried it and confirmed that (5.0.28). Are we maybe talking about 2 different things? I think we're talking about the same thing. Sessions are supposed to be persisted by default. I have nonstandard config (a very sparse server.xml, no explicit Manager You need a Manager. When I said by default I mean out of the box, i.e. with the default server.xml, which has such a Manager IIRC.

If I've understood correctly, because my Manager is not explicitly configured, There's a difference between not explicitly configured and not declared at all. One way to test this is with an HttpSessionListener/HttpSessionActivationListener (one listener can implement both interfaces and thereby capture all four relevant events). It's trivial to write one that just prints out information when sessions are created, destroyed, passivated, and activated.

multiple connectors issues
Hi All, 1. Can you tell me what impact on performance has using many connectors? I need to run additional two connectors (for http and https) to allow some request to be understood as proxied, and others as direct. See the code below. 2. Do request to different connectors share the same session scope? 3. Are classes loaded once for all connectors, or does each connector load its own copy of the classes? In other words, if I have a static member in a class and use 4 connectors, how many copies of this static member will be created? One, or four? I would be very grateful if somebody could clarify this. Thanks in advance, Michal. -- Connector port=20003 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=30003 acceptCount=100 debug=0 connectionTimeout=2 disableUploadTimeout=true proxyName=lxb0754 proxyPort=80/ Connector port=40003 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=50003 acceptCount=100 debug=0 connectionTimeout=2 disableUploadTimeout=true/ Connector port=30003 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 debug=0 scheme=https secure=true clientAuth=false sslProtocol=TLS proxyName=lxb0754 proxyPort=443/ Connector port=50003 maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false disableUploadTimeout=true acceptCount=100 debug=0 scheme=https secure=true clientAuth=false sslProtocol=TLS/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: multiple connectors issues
Hi, 1. Can you tell me what impact on performance has using many connectors? It's largely dwarfed by your app's performance characteristics, unless you're talking about dozens or more connectors. For three or four, it's no big deal. 2. Do request to different connectors share the same session scope? Isn't this so simple to test that it's faster than asking the list? ;) 3. Are classes loaded once for all connectors, or does each connector load its own copy of the classes? No, connectors don't have much to do with classloading at all. How many copies of a given class are loaded into the JVM depends on where the class is located. If you have just one webapp, and the class is in WEB-INF/lib, it will be loaded just once no matter how many connectors you have.

RE: Huge tomcat memory footprint
Hi, Thanks again for your suggestions. I still don't have a good handle on the problem. So please bear with me If I am asking the same questions again. 1. What I have noticed so far is the heap is not growing too much, but the process foot print is growing. I used optimizeit memory profiler to compare snapshots of the heap. I don't see any obvious memory leaks. I need to take a closer look. When I checked this morning, the heap size allocated was 80MB and heap used was 57MB (reported by optimizeit). But the memory sizes reported by solairs pmap command is Size RSSShared Private 1173.45 MB608.125 MB 15.125 MB 593 MB I understand that the process footprint includes other data and would grow as JVM itself grows. But is it normal that it grows to 1173 MB in a matter of few hours. Ofcourse, optimizeit itself has overheads and adds to the process size. But I have seen it grow to 2.5 GB in two days without optimizeit when I was doing some stress tests. I read in one of the solaris virtual memory architecture design paper, that virtual address space of a process on solaris is 4GB. What will happen when the JVM process size reaches 4GB? I guess my confusion is due to the lack of my understanding on how java manages memory and how it relates to the OS-level memory management. Are there any documents or white papers that discuss this kind of issues? 2. I see that GC is running, reclaiming memory periodically. But I noticed that after a while GC is running more frequently and each run takes a substantial amount of time (in one instance GC took about 14 secs). This may affect the throughput, but will it have any impact on the memory? 3. I read somewhere that if you use reflection, the reflective data structures (whatever that means) also contribute to the memory footprint. It sounded as though these are not part of the heap. So if we are creating instances of Method, Constructor, etc, are they not allocated in the heap? We are using reflection heavily. Thanks Anand -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, November 04, 2004 4:55 AM To: Tomcat Users List Subject: RE: Huge tomcat memory footprint Hi, If there is a memory leak in our application, tomcat or java, what are the symptoms I should look for. Will the heap usage (shown by visual GC, optimizeit etc) keep growing and eventually reach the max limit set using -Xmx option to java? Yes, the heap will keep growing and eventually reach the max, at which point you will get OutOfMemoryErrors and hung/unstable behavior. However, if your leak is small, it might take a very long time before this situation is reached. Run your app inside a profiler, conduct some operations typical to your app, and then look at the heap. Most profilers now have features that show you object reference trees, i.e. what objects are holding onto what references. If you see stuff still in memory that you think shouldn't be there, fix it.

RE: multiple connectors issues
Yoav, 2. Do request to different connectors share the same session scope? Isn't this so simple to test that it's faster than asking the list? ;) You're right. I'm getting lazy... So here's the result of my check: multiple connectors share session data. In fact, what counts is the request host address (and not the request port), so multiple connectors share session data as long as requests had the same host address.

RE: Huge tomcat memory footprint
Hi, 80MB and heap used was 57MB (reported by optimizeit). But the memory sizes reported by solairs pmap command is Size RSSShared Private 1173.45 MB608.125 MB 15.125 MB 593 MB There's a mismatch here. There's no way the OS-level overhead is hundreds of MBs for an 80-MB heap. Are you sure the pmap command doesn't multiply by the number of threads or something like that (similar to what the Linux top command does)? of few hours. Ofcourse, optimizeit itself has overheads and adds to the A profiler typically adds an order of magnitude overhead. So for an 80MB heap on the app normally, an 800MB heap with a profiler is within the bounds of reason. But that'd be within the heap and the JVM. process on solaris is 4GB. What will happen when the JVM process size reaches 4GB? Changes are it'll crash. 2. I see that GC is running, reclaiming memory periodically. But I noticed that after a while GC is running more frequently and each run takes a substantial amount of time (in one instance GC took about 14 secs). This may affect the throughput, but will it have any impact on the memory? If GC can't free up memory, then not only will your throughput suffer but it'll be for naught. This is a classic memory leak scenario. 3. I read somewhere that if you use reflection, the reflective data structures (whatever that means) also contribute to the memory footprint. It sounded as though these are not part of the heap. So if we are creating instances of Method, Constructor, etc, are they not allocated in the heap? We are using reflection heavily. Where's somewhere ? ;) That's mostly old information. The JVM is very efficient at handling reflection and properly storing Method references. As you said, you need to look at the profiler more carefully.

Hi, 2. Do request to different connectors share the same session scope? Isn't this so simple to test that it's faster than asking the list? ;) You're right. I'm getting lazy... So here's the result of my check: multiple connectors share session data. In fact, what counts is the request host address (and not the request port), so multiple connectors share session data as long as requests had the same host address. Good ;) Of course the webapp itself also counts for the session, not just the host. http://x/y will have different sessions than http://x/z by default. Thanks for your help and good luck with the school ;-) Thanks ;) Yoav This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: Huge tomcat memory footprint
Hi, 80MB and heap used was 57MB (reported by optimizeit). But the memory sizes reported by solairs pmap command is Size RSSShared Private 1173.45 MB608.125 MB 15.125 MB 593 MB There's a mismatch here. There's no way the OS-level overhead is hundreds of MBs for an 80-MB heap. Are you sure the pmap command doesn't multiply by the number of threads or something like that (similar to what the Linux top command does)? I am not sure how pmap works. But the numbers are consitent with what top command reports. 3. I read somewhere that if you use reflection, the reflective data structures (whatever that means) also contribute to the memory footprint. It sounded as though these are not part of the heap. So if we are creating instances of Method, Constructor, etc, are they not allocated in the heap? We are using reflection heavily. Where's somewhere ? ;) That's mostly old information. The JVM is very efficient at handling reflection and properly storing Method references. I think I read about this in the Java performance tuning book from Sun press or O'reilly.

jk_nt_service.exe stop service gives BAD packet signature
I have problems stopping Tomcat as a service in Windows. I install the service using jk_nt_service.exe (version 5.0.25). When I stop service, I got the following error: Nov 3, 2004 12:16:17 PM org.apache.jk.common.MsgAjp processHeader SEVERE: BAD packet signature 13 00 0d 00 01 00 | . Nov 3, 2004 12:16:17 PM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run SEVERE: Caught exception (java.lang.NullPointerException) executing [EMAIL PROTECTED], terminating thread Looks like what it means is that the jk_nt_service.exe was sending Tomcat a incorrect format message. If this is a bug, I would be very surprised to see that it got through all these times. My guess is are there something wrong with my build of the jk_nt_service.exe or my configuration somewhere. Perhaps bit ordering difference? Could you help? Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat JK2 Connector/IIS Slowdown
Hi Everyone, I'm having some JSP performance problems using the JK2 Connector between Tomcat 5 and IIS6 in Windows Server 2003. If I hit my site as mySite:8080, everything works fine. However, if i just hit mySite, thus going through the JK2 connector, the performance of the JSP pages greatly decreases (load times are about 4-5 times greater). Even stranger is that this slowdown occurs only on some computers and not others. I have already tried setting the enableLookups=false attribute in the server.xml file, but this does not have any effect. Can someone recommend other steps I can follow to improve the performance of my JSP pages when going through the JK2 connector? Thanks, Brett - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

extra directory when using webdav context
This seems a little bizaar. I have the /webdav context running without any problems. I have apache sitting infront of tomcat and am using namebased virtual hosts. I can open the site as a Web Folder (IE6) connecting to port 8080 (tomcat) and it works perfectly. If I connect to port 80 (apache), things work, but I get an extra directory which is called the same thing as the current directory. E.g. If I navigate into a directory x that has nothing in it (on the filesystem), the webdav client shows directory x. I can click on this directory and x shows up again, and so forth. I'm not sure if this is a problem with tomcat, apache, or the connector. Anyone experience this before? I can post config files if required. Note: versions are Apache 2.0.51, Tomcat 4.1.30 Cheers, Brad Brad Hafichuk Azus Technologies Inc. www.azus.net (403) 710-8079

j_security_check forward, https client - surrogate squid - http tomcat
Hello all, I have the following configuration: Inet client (HTTPS) - proxy/firewall surrogate server (squid-2.5.STABLE5) openbsd - HTTP - origin server (Apache/1.3.29 - jakarta-tomcat-4.1.30) openbsd We have our SSL certs on the squid server and to keep data secure over the internet, squid passes valid requests inside to our webserver / application server. Everything works fine if the client is using HTTP. Everything works fine if the client is using HTTPS _EXCEPT_ if the application resides within a tomcat authentication realm. The problem is once a client authenticates the j_security_check module forwards them to an absolute HTTP URL because between the squid proxy and the webserver everything _IS_ just HTTP. So once they authenticate they end up with HTTP instead of HTTPS. Granted this is probably the expected behavior and there is nothing wrong with this except that I need it to be HTTPS when the request is HTTPS. My question, where should I fix this problem? Is there someway to make a relative HTTP 302 redirect from j_security_check (not sure on the validity of that)? Should I do some manipulation at the squid level (not sure how)? Pretty much what I need is if the request from the client was HTTPS I need the redirected page to be HTTPS. All internal requests from internal clients (non INET) are HTTP and those are all fine. Thank you
Does temp clean itself up?
Hey Folks, This may be a stupid question, but is the %CATALINA_HOME%\temp directory, really a temp directory in that it will clean itself out after a certain amount of time. If yes, how often does it perform clean-up and can this be configured. I just want to make sure that when I install Tomcat 5.0.28 on a Windows 2003 server with a small amount of hard drive space, that the %CATALINA_HOME\temp will clean itself up periodically so it won't fill-up my disk space.

RE: Tomcat JK2 Connector/IIS Slowdown
Brett, I have a similar problem. But what is interesting is that it only seem slow when I test using a Windows 2000 pro box using IE 6 against a Windows 2003 Server. Try using an XP pro box to test the same functionality. Also, here are diagrams that explain the situation I am having. I have submitted the issue to Microsoft and have one of their engineers on the case. I will keep everyone posted on what they discover. (please view this email in plain text for diagrams to display correctly below) File Download from ONE is slow, ALL others are FAST Windows 2003 Server:Windows 2000 Professional |---| |---| | Tomcat 5.0.28 | SLOW| | | IIS6|- | IE6 | | JK2 | FROM CART | | |---| |---| Windows 2003 Server:Windows 2000 Professional |---| |---| | Tomcat 5.0.28 | FAST| ANY OTHER | | IIS6|- | BROWSER | | JK2 | FROM CART| | |---| |---| Windows 2003 Server:Windows XP and Mac OSX |---| |---| | Tomcat 5.0.28 | FAST| IE 6 | | IIS6|- | or Safari | | JK2 | FROM CART| | |---| |---| Windows 2003 Server:ALL recent OS's |---| |---| | Tomcat 5.0.28 | FAST| All recent| | (running on |- | browsers | | port 8080 standalone) | FROM CART| | |---| |---| RedHat LinuxALL recent OS's |---| |---| | Tomcat 5.0.28 | FAST| All recent| | Apache 2.0.x|- | browsers | | JK2 | FROM CART| | |---| |---| Downloading a 1.3M file from a website cart to a Windows 2000 Pro desktop running latest IE 6 is slow and takes 15 seconds Downloading the same 1.3M file to a Windows XP box running IE 6, a Windows Pro box running Mozilla, and a Mac OSX running safari takes approx 1 second Spoke with Microsoft, we put a 1M file in a virtual directory on IIS. It downloaded in approx 1 second to Windows Pro / IE6. When I take IIS/mod_jk out of the picture, and go directly to Tomcat on 8080 the download is fast to All OS's and Browsers. Also, Apache has no problem downloading the file fast to All OS / browser combinations, including Windows 2000 / IE6!!! So does anyone know why the download is slow between IIS 6 and Windows 2000 Pro / IE6 and fast to all other clients. Is there something I can do to my IIS server to make the download go faster. Two other facts that are important... 1. the file being downloaded from the cart is on a remote file server and is being published through IIS via a UNC path from a shared folder. This is true for all scenarios shown above. And, 2. We are required to run IIS 6 in IIS 5 isolation mode due to the isapi_redirector2.dll can not handle IIS 6 native mode under large loads. I did try to do the download running IIS 6 in native mode, but the download was still slow. Seems to be a weird buffer restriction when IIS 6 and IE6 on Windows 2000 talk to each other. Confounded.

If I hit my site as mySite:8080, everything works fine. However, if i just hit mySite, thus going through the JK2 connector, the performance of the JSP pages greatly decreases (load times are about 4-5 times greater). Even stranger is that this slowdown occurs only on some computers and not others. I have already tried setting the enableLookups=false attribute in the server.xml file, but this does not have any effect.

RE: sessionS info persistence when restart Tomcat
Following Yoav's earlier comments I've implemented a basic class SessionLogger that implements HttpSessionListener, HttpSessionActivationListener, HttpSessionAttributeListener, ServletContextListener. It just writes amessages to stdout using System.out.println() to log when each event fires, including each of the interface events plus instantiation and finalization of SessionLogger itself. I've configured it in web.xml: listener listener-classcore.servlet.SessionLogger/listener-class /listener SessionLogger logs its own presence OK when I instantiate it, and happily logs events as expected on sessions, and session attributes. It logs context creation but not destruction. Here's some sample catalina.log lines for starting TC, logging in, logging out, logging in again: 2004-11-05 00:56:50 StandardContext[/ao]*** SERVLET CONTEXT: initialized 2004-11-05 00:58:08 StandardContext[/ao]*** SESSION EVENT: sessionCreated, [EMAIL PROTECTED] 2004-11-05 00:58:23 StandardContext[/ao]*** SESSION ATTRIBUTE EVENT: attributeAdded, LOGGED_IN_USER, [ID=1] 2004-11-05 00:58:30 StandardContext[/ao]*** SESSION ATTRIBUTE EVENT: attributeRemoved, LOGGED_IN_USER, [ID=1] 2004-11-05 00:58:30 StandardContext[/ao]*** SESSION EVENT: sessionDestroyed, [EMAIL PROTECTED] 2004-11-05 00:58:30 StandardContext[/ao]*** SESSION EVENT: sessionCreated, [EMAIL PROTECTED] 2004-11-05 00:58:34 StandardContext[/ao]*** SESSION ATTRIBUTE EVENT: attributeAdded, LOGGED_IN_USER, [ID=1] However if I then stop TC, I get nothing logged at all after the attributeAdded event.

RE: sessionS info persistence when restart Tomcat
SessionDestroyed shouldn't be called when tomcat shuts down. Otherwise, the session wouldn't be valid when it starts up. I just tested with a clean install of 5.0.29 with a similar listener to the one you describe. SessionDestroyed was not called when I stopped TC but the sessions were still valid when I started it up. I can give you the war file if you like. Do all of the attributes that you're adding to your session implement Serializable? C:\jakarta-tomcat-5.0.28\work\Catalina\localhost\ao\SESSIONS.ser (The system cannot find the path specified) Does tomcat have sufficient permissions to write to the work directory?

Re: dear friend i'm in a big trouble
First, is your servlet in a package? Non-packaged servlets will not work. Did you map your servlet in web.xml? What is the URL you are using to call the servlet? You don't need to set a classpath environment variable Tomcat sets it's own. Did you install a full j2sdk or just a jre? Tomcat 5.0 and lower needs a full j2sdk. Did you set your JAVA_HOME enviornment variable? Have you tested it to make sure it's right? or.. If you installed as a Windows Service, did you make sure that the installer found the full j2sdk on your system and not another JRE?

Re: dear friend i'm in a big trouble
http://localhost:3030/servlet/HelloClientServlet Looks like you are depending on the invoker servlet to instanciate your servlet. The invoker servlet is no longer active by default. You will need to map your servlet in web.xml. Again, your servlets need to be packaged. On Thu, 2004-11-04 at 21:29, Ben Souther wrote: First, is your servlet in a package?

Re: connection pooling
Hi all, I'm returning to a problem I couldn't solve the first time, about two months ago, and still can't seem to figure out. I can't get a db connection using connection pools. I get the exception listed below, same as so many have previously, but nothing I've found seems to works. Below are my specs. Anyone with concrete advise/direction on how to get this working?

Re: Huge tomcat memory footprint
Anand The pmap command itself gives some good info on this huge memory footrpint. There will be jars, some libraries (JVM specifc) are loaded into the memory that can cause this footprint. You can find the list of jars/files loaded by using the inode number. In addition sometime i observed that if the System memory (RAM) is low, it tends to show a larger footprint. -Surendra - Original Message - From: Anand Narasimhan [EMAIL PROTECTED] To: 'Tomcat Users List' [EMAIL PROTECTED] Sent: Thursday, November 04, 2004 11:52 PM Subject: RE: Huge tomcat memory footprint -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, November 04, 2004 9:59 AM To: Tomcat Users List Subject: RE: Huge tomcat memory footprint Hi, BTW, have you moved from JDK 1.4.1 to 1.4.2 yet, and if so has that made a difference?

session-timeout means tomcat restart
Hi, I'm experiencing 2 interesting problems that may be related to my session timeout. 1. It seems that when my session times out I need to restart tomcat, often just the application via reload in the manager, in order to gain access to my db again. Could this be because I've been accessing the db via jdbc hard coded in the servlet? Might using a datasource connection pool take care of this? 2. Often tomcat hangs without responding at all, to static or dynamic requests, after it's been left for an hr or more with no interaction. Might this be related to the memory leaks I hear about? thx Eric - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Fw: Re: Problem with Tomcat 4.1 Charset - Resolved!
Hi List! My problem with the appended charset is resolved, thanks to Mark Sutton who sent me his solution and told me to share it with the list if it worked out! So after I deinstalled Tomcat 4.1.30 and turned to the new production release 5.0 everyhting worked fine! And I can definitly say that IE can not cope with Content-Type: application/pdf; charset=ISO-8859-1 it looks like it was a bug in the tomcat-server, so thanks for your time and if somebody else has this problem: An update helps!

I had a similar problem with PDFs and it seemed to be this bug: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24970 that was causing the problem. I wasn't aware that this was a Windows-only bug though. This bug was not present in 4.1.27 and only manifested itself when I tried 4.1.29. It doesn't cause problems with version 5.0.x.

( esponse.setHeader(Content-disposition,inline;filename=generated.pdf ); ) But this does not work on all browsers! On some IE Versions the adobe-plugin is loaded (you see the splash-screen) and then the page remains white. No PDF and no adobe is displayed! So this does not work either! But if I use content-disposition on the linux-server it works (as it worked without content disposition) I use the exact same files on the exact same data. When I save the files look for the difference the only thing I find is the additional charset= ... on the non working version.

Instead of messing with the charset stuff, make sure to set a content-disposition header on your response. Google for it if you're not sure what it is: it's simple and there are tons of examples online. This is the only way to ensure somewhat consistent behavior across browsers for this use-case.

I've got a big problem to solve. On a windows server I installed an acutal jsdk and tomcat 4.1. Now I developed a jsp-Servlet that sets it's content-type to application/pdf and only writes pdf-data out. If I run this on my testserver with tomcat 4.0 (debian/linux) everything runs fine and Internet Explorer is able to open the pdf. But if I merge to the production server (tomcat 4.1/win 2k3) (- not my choice :) ) and try to acces the exact same page I get a funny error! Internet Explorer tells me to save the file to disc! It took me a long time to figure out that the only difference is in the headers! = The Linux Machine wirtes: Content-Type: application/pdf = The Windows Machine wirtes: C ontent-Type: application/pdf;charset=ISO-8859-1 Because of this additional charset Internet Explorer is no longer able to start the pdf-Viewer and display the file inline. Attached are some snips from the code: --SNIP-- //response.setHeader(Content-disposition,inline; filename=generated.pdf); //
AW: {an alternative}Re: connection pooling
HI Eric,
I have seen the same error your are getting. I am using tomcat 5.0.28.
Make sure that you have removed the expanded war directories, from
webapps and ${CATALINA_HOME}/work before restarting.
Also look inside
those other context.xmls inside ${CATALINA_HOME}/conf/Catalina/localhost
and make sure that they do not define a context with path=/wms.
Cheers,
nick.

Atishay, the DefaultContext does work once I comment out the other
Engine element. You mentioned that means something is wrong with my
Context? So what next?
many thx

This did not work. In looking for the Engine element you speak of I
didn't find it exactly. I did find it with it with an extra attribute
Engine name=Standalone... jvmRoute=jvm1. Furthermore, this

Engine name=Catalina... element. I tried with and without the
jvmRoute element. No success. Same exception.
