How to check if the client dropped the connection
Hi, I'm working on the development of an open source application, GeoServer, implementing the Web Map Service specification. The specification allows a client to request maps using simple GET requests like: http://sigma.openplans.org:8080/geoserver/wms?WIDTH=431SRS=EPSG%3A4326LAYERS=tiger-nyHEIGHT=550STYLES=FORMAT=image%2FpngSERVICE=WMSVERSION=1.1.1REQUEST=GetMapEXCEPTIONS=application%2Fvnd.ogc.se_inimageBBOX=-74.01697805908182,40.69808217724622,-73.99567744140603,40.72526393994153 and the client gets back a PNG with a map of the request area. No asynchronism is allowed, the protocol is standardized (http://portal.opengeospatial.org/files/?artifact_id=1058) and I have no controls over the clients (there are tens of them around, both open source and proprietary) which are free to make as many request as they like, in whatever order the like. By spec we're forced to use a plain request and response approach, but we're experiencing a problem with clients making lots of request as the user zooms/pans around: basically a request is made, but the user keeps on moving, the client drops the older requests (closing the connection in face of the server) and makes others. Unfortunately in the meantime the older requests are still running, drawing a map takes time and a lot of memory, for example the above request, which is a small one btw, allocates a BufferedImage of 700KB. The memory is consumed up until the image is encoded out to the stream, which is also the moment we finally figure out the client dropped the connection (since writing to the servlet output stream fails). This is very sub-optimal. Servers like Apache with cgi do kill the cgi process the moment the connection is dropped, significantly reducing the server load both in terms of CPU and memory consumption. Is there any way to check if the client connection is still open using only the standard servlet API? If not, is there any Tomcat specific approach that might work instead? If there is no solution that can be applied at the general servlet api level, do you know of any Tomcat specific approach one could use? e.g., casting the HttpServletResponse to some Tomcat specific class and get some connection information status there?

Non-http tcp protocol
Hi all, I'm trying to figure out how to use tomcat as a TCP server. The basic idea is to receive tcp connections, through a given port, process them and return a response. Has anyone done it? I've googling but I've not found much information. Which do you think is the best/simplest way to do it?

Tomcat JK connection problem ?
Greetings all, I have configured JK connector to bridge Apache to my Tomcat server. I am getting weird behaviour for a one particular servlet. For a random client , it seems that Apache serves some cached page.Seems it shows some kind of cached page of JSP page called 'Error.jsp'. I have placed a System.out.println(error JSP called); inside this JSP but this method does not get called. When user open the page from another browser, it serves the correct page and error moves to another client! I have placed System.out.println(POST); and System.out.println(GET); on top of doPost() and doGet() methods of the servlet ,and when this happens there's no output in the Tomcat output.(ie these methods are not called atall). When users access using 8080 port , everything works fine.Is some kind of caching involed inside JK connector ? Any tips ? My 'workers.properties' file : # Define 1 real worker using ajp13 worker.list=worker1 # Set properties for worker1 (ajp13) worker.worker1.type=ajp13 worker.worker1.host=XXX.XXX.XXX.XXX worker.worker1.port=8009 Thanks in advance. umanga - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Tomcat JK connection problem ?
2009/9/28 Ashika Umanga Umagiliya auma...@biggjapan.com Any tips ? When posting about a complex environment such as httpd + mod_jk + Tomcat, a good tip is to include version information - we're far more likely to be able to help you! - Operating system and version - Java version (and whether it's a JDK or a JRE) - Tomcat version (right down to the last digit - 6.0.20, not Tomcat 6.0) - mod_jk version - httpd version Is there anything in common between the clients that appear to be getting the cached page? All one company? All one browser? All one login to your app (if you have logins)? Regards, - Peter

Re: Tomcat JK connection problem ?
As far as I can see, the log file contains the same situation as when I connet to the URL with a browser. I do successfully get the main page, but the page includes two invalid references: - for style.css (should be maybe css/style.css) - and inside css/style.css which is also used in addition to the wrong style.css it has a reference to images/bg_001.png, which should likely have been a ../images/bg_001.png. Furthermore the page contains two xml headers: - !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN and later down another - !DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01 Transitional//EN http://www.w3.org/TR/html4/loose.dtd; which doesn' seem right. I can't see any occurence of a caches Error.jsp, but I do see broken links which obviously send the Tomcat standard error page to the browser instead of the css file resp. the png file.

Re: Non-http tcp protocol
hello,
take the simpliest example from a java book.
this is one:
public class BasicTCPServer extends AbstractServer implements Runnable{
/**
* The port to listen on.
*/
private int port;
/**
* The listening socket.
*/
private ServerSocket serverSocket;
/**
* True as long as we are running.
*/
private volatile boolean running;
/**
* Creates a new server with the given port and connection factory.
* @param aPort the port to listen to.
* @param conFactory
*/
public BasicTCPServer(int aPort, IConnectionFactory conFactory){
super(conFactory);
port = aPort;
}
@Override public void startServer() throws ServerException{
try{
serverSocket = new ServerSocket(port);
}catch(IOException e){
throw new ServerException(Couldn't bind port: +port+
: +e.getMessage());
}
new Thread(this).start();
}
@Override public void run(){
setRunning(true);
while(isRunning()){
try{
Socket s = serverSocket.accept();
IConnection newConnection =
getConnectionFactory().createConnection(new SocketContext(s));
notifyConnectionCreated(newConnection);
newConnection.open();
}catch(IOException e){
e.printStackTrace();
}
}
}
/**
* Stops the server.
*/
@Override public void stopServer() {
setRunning(false);
}
regards
Leon
P.S. you can checkout the code under
svn://svn.anotheria.net/opensource/ano-net/trunk with a ready to use
tcp client/server, udp client/server and so on.

blocked / hanging on call to HandlerRequest.checkRequest
Hi I'm running tomcat 5.5.25 on debian sarge 32 bit linux (2.6.8 kernel) with ~ 1.5GB ram on a pentium 4 2GHz with a mysql db 5.0.27 I've got a configuration with apache mod_jk 1.2.25 balancing to 2 tomcats which are both running running on jdk 1.6.0_16 -Xmx=256M periodically, generally at busy times, looking at the JK Status Manager the busy count on one of the tomcats will go up and the requests channelled through that container will start to hang, the busy count will steadily increase the throughput will drop dramatically (i.e. the Acc column in jk_status will stop incrementing by 30 every 10secs and go down to like 4), This will continue until I either stop that tomcat member through the JK Status Manager - by editing the worker settings or the thread count goes up to over the number of permitted apache requests (at 150 at the moment) and apache is restarted automatically by an out of process monitoring app. If I stop the tomcat instance through the JK Status Manager, then the busy count will gradually (over a period of 5 - 10 mins) decrease and get to 0. I took a thread dump by tee-ing the output of catalina.out and then sending a kill -SIGQUIT pid when it was in the described busy state and lots of threads The crux of that seemed to be a lot of threads blocked / waiting for lock on a lock / monitor held in the HandlerRequest.checkRequest here is the printout of the thread holding the lock which is in the RUNNABLE state: TP-Processor65 daemon prio=10 tid=0x08bc9400 nid=0x54bd runnable [0x55dd] java.lang.Thread.State: RUNNABLE at java.lang.Class.getMethod(Class.java:1605) at org.apache.commons.modeler.BaseModelMBean.setManagedResource(BaseModelMBean.java:764) at org.apache.commons.modeler.ManagedBean.createMBean(ManagedBean.java:393) at org.apache.commons.modeler.Registry.registerComponent(Registry.java:835) at org.apache.jk.common.ChannelSocket.registerRequest(ChannelSocket.java:466) at org.apache.jk.common.HandlerRequest.checkRequest(HandlerRequest.java:357) - locked 0x4490ee38 (a java.lang.Object) at org.apache.jk.common.HandlerRequest.decodeRequest(HandlerRequest.java:367) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:261) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:619) then lots of the following types of threads (e.g. 35) all blocked TP-Processor63 daemon prio=10 tid=0x09ddc800 nid=0x549f waiting for monitor entry [0x55d3] java.lang.Thread.State: BLOCKED (on object monitor) at org.apache.jk.common.HandlerRequest.checkRequest(HandlerRequest.java:357) - waiting to lock 0x4490ee38 (a java.lang.Object) at org.apache.jk.common.HandlerRequest.decodeRequest(HandlerRequest.java:367) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:261) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:619) TP-Processor62 daemon prio=10 tid=0x09dd4c00 nid=0x549e waiting for monitor entry [0x55ce] java.lang.Thread.State: BLOCKED (on object monitor) at org.apache.jk.common.HandlerRequest.checkRequest(HandlerRequest.java:357) - waiting to lock 0x4490ee38 (a java.lang.Object) at org.apache.jk.common.HandlerRequest.decodeRequest(HandlerRequest.java:367) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:261) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Thread.java:619) .etc here is a typical reading from the JK Server Manager for the for the balanced members NametomcatA Typeajp13 Hostlocalhost:8011 Addr127.0.0.1:8011 Act ACT State OK D 0 F 100 M 1 V 104 Acc 42540 Err 0 CE 426 RE 0 Wr 34M Rd 792M Busy80 Max 92 Route tomcatA RR Cd Cd 0/0 NametomcatB Typeajp13 Hostlocalhost:8012 Addr127.0.0.1:8012 Act ACT State OK D 0 F 100 M 1 V 97 Acc 42719 Err 0 CE 377 RE 0 Wr 39M Rd 807M Busy4 Max 57 Route tomcatB RR Cd Cd 0/0 I'm been

Re: How to check if the client dropped the connection
Hi Andrea. When the client disconnects, and your servlet tries to write to the output stream, Tomcat will throw a ClientAbortException (you may have already seen this): http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/connector/ClientAbortException.html Tomcat appears to only throw this exception when you either write some bytes to the output stream or when you flush the output stream, and the client already closed its end of the connection. It appears that you could periodically try flushing the output stream and see if doing so throws this exception. You can flush after writing any number of bytes, including zero bytes. The first time you call flush, it will send the HTTP response headers to the client, so you would need to first set the headers before flushing. That sounds difficult for you to do because you're writing an image, and one of the headers would be Content-Length, which you probably don't know until your image is generated. -- Jason Brittain On Mon, Sep 28, 2009 at 12:21 AM, aaime74 andrea.a...@gmail.com wrote: Hi, I'm working on the development of an open source application, GeoServer, implementing the Web Map Service specification.

No asynchronism is allowed, the protocol is standardized (http://portal.opengeospatial.org/files/?artifact_id=1058) and I have no controls over the clients (there are tens of them around, both open source and proprietary) which are free to make as many request as they like, in whatever order the like. By spec we're forced to use a plain request and response approach, but we're experiencing a problem with clients making lots of request as the user zooms/pans around: basically a request is made, but the user keeps on moving, the client drops the older requests (closing the connection in face of the server) and makes others. Unfortunately in the meantime the older requests are still running, drawing a map takes time and a lot of memory, for example the above request, which is a small one btw, allocates a BufferedImage of 700KB. The memory is consumed up until the image is encoded out to the stream, which is also the moment we finally figure out the client dropped the connection (since writing to the servlet output stream fails). This is very sub-optimal. Servers like Apache with cgi do kill the cgi process the moment the connection is dropped, significantly reducing the server load both in terms of CPU and memory consumption. Is there any way to check if the client connection is still open using only the standard servlet API? If not, is there any Tomcat specific approach that might work instead? If there is no solution that can be applied at the general servlet api level, do you know of any Tomcat specific approach one could use? e.g., casting the HttpServletResponse to some Tomcat specific class and get some connection information status there?

Upgrade from 5.5.9 to 5.5.20 Help
Hello, I have never upgraded Tomcat before and need to upgrade it from version 5.5.9 to 5.5.20 for application compatibility. I had a search through the documentation and didn't come across a section on how to do this type of thing (maybe I missed it). Can someone point me in the right direction here? From version: 5.5.9 To version: 5.5.20 OS: Windows Server 2000 IIS: IIS 5 using IIS Redirect for SSO purposes (application requirements) Other than that it is a pretty vanilla installation. Thanks in advance, Simon.

My approach was to dynamically cache requests that the client may want to make in advance. An easy example would be if a client makes a request for the city center, you create the map for the city center plus the suburbs around it and store it somewhere, then return the city center. If the user then moves around a bit to see the suburbs, you already have the whole map cached and just need to return it, no need to do any further calculation. If you then also compress the image on the fly while you are reading it from disk (or from some memory cache), you will start writing to the output stream very soon (also detecting the dropped connection very soon) and the servlet will not need much RAM. Of course this does not work if you just use Java's built-in PNG encoder. Obviously, caching always comes with the price that you will have the occassional cache miss :-) That is, this does not work for every request but may decrease load and RAM usage a lot for typical use cases. In your OP you write: Unfortunately in the meantime the older requests are still running, drawing a map takes time and a lot of memory, for example the above request, which is a small one btw, allocates a BufferedImage of 700KB. This indicates that you (1) seem to not use any caching (drawing a map takes time - with caching the map would already have been drawn) and (2) you use BufferedImage which of course does not allow you to PNG-encode on the fly. Both problems would be solved with the above suggestion. Markus - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
RE: Apache/Tomcat with SSL
As suggested by André, you may want to join the Apache User's list and ask there your question. You need to configure SSL in your Apache web server. To configure SSL Apache Web server, the first thing you need to do is to verify that the module mod_ssl is available.

That sounds difficult for you to do because you're writing an image, and one of the headers would be Content-Length, which you probably don't know until your image is generated. Actually, Content-Length is optional as per the HTTP-1.1 spec: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html However, my take on the OP is that a better optimization strategy in this case would be to just cache a larger image on the server rather than generating every image on-demand. That is, when the user is moving around in the image, the server, on the first request, would calculate the image for a much larger portion of the map than requested and stores it on disk in temporary storage (or in some cache area in RAM, if feasible, after all RAM is cheap these days and 64-bit machines can have lots of RAM). Storage of the images would not be done all at once but in tiles. When then user then moves around in the client, the requests just reads the tiles of the created image from disk, puts them together and clips the borders, then compresses the image and sends it to the client. It is possible that PNG even has some support for compressing parts of an image so the tiles itself could be already stored in compressed format, but it's been a while since I read the PNG spec last time. The same could be done for zooming by storing images in a pyramidal structure, like it is done in pattern recognition. While the user is moving, a background thread associated with the client could try to anticipate where the user is likely to be moving to and calculate the given tiles in advance.

Re: How to check if the client dropped the connection
Martin Gainty schrieb: could you explain just a bit more what is a tile? If you have a very large image, say 1 million x 1 million pixels or something like that, it is more efficient to split the image into tiles, that is small images of, say, 256 x 256 pixels. If a certain portion of the big image is requested, you can then load these tiles individually from disk and put them together to form the portion of the image that was requested. Tiles which are inside the requested image portion can be used as is, tiles at the borders may not be contained fully in the requested image and must possibly be clipped. How tiles are used can be seen e.g. in Google Maps: when you have a slow internet connection, while scrolling you can actually see that the map consists of rectangular tiles which are loaded on demand. This is more or less the same concept as blocks when doing paging of virtual memory or pages when talking about processor caches. Even Audacity (audio editor) uses this concept to achieve fast editing of very large audio files.

May I suggest that you just upgrade to the latest version (5.5.28)? 5.5.20 seems have been released very late 2007 - there's been substantial work/bugfixes done since then. The config (assuming your original is correct) will be identical, so you should be able to install a new copy from tomcat.apache.org, and pretty much copy paste the contents of your various config files. It is worth noting, however, that writing a fresh config is often a good idea - especially if you've repeatedly carried old configs over from ancient versions.

Hi I'm running tomcat 5.5.25 on debian sarge 32 bit linux (2.6.8 kernel) with ~ 1.5GB ram on a pentium 4 2GHz with a mysql db 5.0.27 I've got a configuration with apache mod_jk 1.2.25 balancing to 2 tomcats which are both running running on jdk 1.6.0_16 -Xmx=256M periodically, generally at busy times, looking at the JK Status Manager the busy count on one of the tomcats will go up and the requests channelled through that container will start to hang, the busy count will steadily increase the throughput will drop dramatically (i.e. the Acc column in jk_status will stop incrementing by 30 every 10secs and go down to like 4), This will continue until I either stop that tomcat member through the JK Status Manager - by editing the worker settings or the thread count goes up to over the number of permitted apache requests (at 150 at the moment) and apache is restarted automatically by an out of process monitoring app. If I stop the tomcat instance through the JK Status Manager, then the busy count will gradually (over a period of 5 - 10 mins) decrease and get to 0. I took a thread dump by tee-ing the output of catalina.out and then sending a kill -SIGQUIT pid when it was in the described busy state and lots of threads The crux of that seemed to be a lot of threads blocked / waiting for lock on a lock / monitor held in the HandlerRequest.checkRequest here is the printout of the thread holding the lock which is in the RUNNABLE state: If you just want the problem to go away, then look for the attribute request.registerRequests in http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html . If that is set to false, then there is no locking within the checkRequest method. You lose that ability to get stats for the request threads via JMX (including the manager status page), but that method also quits being a bottleneck if you get a flood of new requests.

Re: Apache/Tomcat with SSL
The most common cause of this is that you haven't copied your JkMount etc configuration statements to the SSL VirtualHost. In this case, mod_jk doesn't think that it should be serving the .jsp file, so Apache (httpd) serves it instead. Since httpd knows nothing about JSP, it just serves it as a text file. As other people have pointed out, unless you really know what you are doing, it is generally a bad idea to share the httpd DocumentRoot with the Tomcat webapps directory. And even if you do really know what you are doing, it is a significant amount of extra work to secure this configuration.

Re: Apache/Tomcat with SSL
Miguel, Do you have Tomcat serving up Port 80 traffic or is that Apache's httpd? I suggest you have one web server handle both normal web traffic and SSL traffic (if possible), since this page is a login page, you might want to FORCE https on that page and not allow HTTP. It would almost appear that you have Tomcat serving up port 80 traffic and Apache serving up SSL/TLS connections. So if that were the case, use Tomcat to do the SSL as well and configure tomcat accordingly in the server.xml file. Do keep in mind there is a difference between Tomcat and Apache (httpd). Please clarify your setup for us.
