If the resources are application - specific, you don't need to do this at all. Just add the files to your local application. In Maven, there's a special directory for that: src/main/resources In NetBeans, I normally create a separate package for all of my configuration files. I think in Eclipse you'll have to make a subdirectory under WEB-INF/classes and copy the files there. That's unpleasant. Eclipse will include that in the build of the WAR file when you do an export. Then, just do the following in your code to reference the resource. InputStream in = this.getClass().getClassLoader().getResourceAsStream(configfile); Where configfile is the complete classpath to your resource. This is nice. It works in exploded WARs, it works in WAR files, it works in JARs. No mucking about with CLASSPATH. No polluting other applications or Tomcat with spurious application - specific resources. This enables you to run several copies of the same web application in the same container, all with different configurations. Just search for getResourceAsStream() for more explanation.

Probably not a good idea to place them here unless you really know what you are doing and have a specific reason for doing it.

But since yesterday my application reporting the error that properties file doesnt exist in classpath/path In order to fix then i created the lib folder in my CATALINA_BASE placed my properties/resource file over there, which eventually fixed my application CLASSPATH issue. But the thing which makes me wonder that how my application was able to access the properties file earlier when i placed it CATALINA_BASE/bin location what makes it to stop now. Kindly suggest what all can be the scenarios/prossible use case for this, TOmcat version - 6.0.35 Thanks

[Probe]- Tomcat deployment
Hi Guys, Is there a way by which we can handle the tomcat deployment of war files from a central location via a Web UI screen ? I 'm aware of PROBE (http://code.google.com/p/psi-probe/) by which we can do the deployment from a Web UI screen but for that we need to individually deploy the Probe.war across all instances . Is there a way out by which we can handle the tomcat deployments from a central location ( i.e by avoiding deploying probe.war on all instances) on todifferent physical machines. Please suggest share your valuable thoughts Thanks Vicky

Kindly suggest how to do it. You want to do one of two things: 1. Just rename dummy.war to market.war. I don't know why so many people resist the simplest possible way to do this. 2. Move dummy.war outside of Tomcat's auto-deployment directory (which defaults to CATALINA_BASE/webapps/). Put your Context element into the file CATALINA_BASE/conf/[service]/[host]/market.xml and point docBase to where you put your WAR file.

Remote restart capabilities are a dangerous business (e.g. an HTTP listener that knows how to restart services), so I would avoid them if I were you. Restarting a Tomcat instance should be fairly rare, no? If you use jsvc, all your devs need to be able to do is send a signal using kill.

Re: Threads is it equal to no. of open sockets
Thanks Chris for an insight. When you say the number of open sockets and the number of Tomcatrequest-processing threads will be the same. Does that mean all sockets states whether its in Closed_wait,listening, stop etc... will consume a thread individually.If yes then does that imply if i count all the sockets bind to http port (all states ) it should not exceed the total no. of threads configured for my hTTP connector.But in certain cases i've seen that this count of sockets is more than the threads configured , is there any particular reason for this behavior. -vicky On Tuesday, 16 June 2015 10:50 PM, Christopher Schultz ch...@christopherschultz.net wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Vicky, On 6/16/15 12:50 PM, vicky wrote: Server version: Apache Tomcat/7.0.22 Server built: Sep 27 2011 09:40:50 Oh, wow, you really need to upgrade.

The BIO connector stands for blocking I/O, and each request is processed by a single thread from start to finish, and each thread will wait for a new connection to come in before being dispatched.

Please help in understand. If you want to monitor Tomcat, I suggest you read this: http://wiki.apache.org/tomcat/FAQ/Monitoring It talks about watching the thread usage. You can certainly watch thread usage over time as well and see how many threads are in use. Application slowness can be caused by any number of things, but usually thread-usage isn't the problem unless you have a huge load and a well-designed application. It's usually things like global synchronization of certain resources, or too few database connections, a database that hasn't been optimized properly for the load profile, or inefficient handling of large amounts of data (e.g. using DOM instead of SAX for XML document processing). That said, you might still have a threading problem. - -chris Connector port=8080 protocol=HTTP/1.1 connectionTimeout=2 redirectPort=8443 / Also, what Tomcat version? I'm guessing 6.0.x or 7.0.x.

TCP connection vs Tomcat threads vs File Descriptors - please help
Hi All, can someone please help in understand that how TCP connections are interlinked with the no. ofFile Descriptors & no of threads configured over a machine . Setup details :OD - Centos 6Tomcat7Java 7 Recently i have faced an problem in while my application was having +20k TCP connections in TIME-WAIT state resulting in choking my application though no consumed threads & Files descriptors are pretty less than threshold. 1) I would like to understand that is there any limit that how many TCP connections a machine can open , IF YES then how to tune it . 2) Second query , my understanding was every TCP connection will open one file descriptor but in my currentsituation only 900 FD were used whereas the TCP_WAIT connections where +20K .Kindly suggest how do i comprehend this . How these are interlinked 3) If i configure 600 threads in server.xml for my HTTP connector & if i'm running that machine over 8 core cpu does that mean simultaneously 600 X 8 (cpu core) =4800 threads will be served by my tomcat ?

Let me give you an incomplete answer: A TCP connection in state TIME_WAIT does no longer exist from the point of view of the application/Tomcat/Java etc. So it does not need any application resources like threads. To understand TIME_WAIT, you should look for "TCP state diagram" in your favorite search engine or grab a copy of Steven's TCP/IP illustrated. You will find a picture like this: http://www.cs.northwestern.edu/~agupta/cs340/project2/TCPIP_State_Transition_Diagram.pdf (page 2) There you will see, that an ESTABLISHED connection can only enter TIME_WAIT state on the side of the connection, that first started the connection shut down by sending a FIN packet. And on that side it will always go through TIME_WAIT state. The default time during which a connection sits in TIME_WAIT on Linux seems to be 60, sometimes 120 seconds. So the total number of connections in that state is proportional to the number of connections per second that the local node starts closing. Example: Assume you run 100 new connections per second and all of the are closed by the local node first. That means in 60 seconds 6000 connections will pile up in state TIME_WAIT. In addition, removing TIME_WAIT connections from the OS list is not done continuously but in regular intervals, like e.g. every 5 seconds. So the real numbers can be slightly higher. Why are TIME_WAIT states bad? They don't need app resources, so why care? Because the increase the list of TCP connection states the OS has to manage and a huge number of such TIME_WAIT connections - a few 10.000s - can make the IP stack slower. The TIME_WAIT duration is not configurable for Linux only on some other Unixes. See the discussion at: http://comments.gmane.org/gmane.linux.network/244411 For some time you had to live with it and the only things you could do was - checking whether you could force more connections being closed by the remote side first - reducing the number of connections per second by increasing connection reuse, so keeping connections around for a longer time instead of constantly creating new ones. Both options would increase the need for app resources though, because the longer lifetime of established connections would often increase the number of threads needed. Now some people recommend using net.ipv4.tcp_tw_reuse, but that tunable seems to only apply to outgoing connections. Other suggest using net.ipv4.tcp_tw_recycle, but that one seems to make problems if clients sit behind a NAT device. See: http://vincent.bernat.im/en/blog/2014-tcp-time-wait-state-linux.html Other people suggest tuning net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait: http://www.lognormal.com/blog/2012/09/27/linux-tcpip-tuning/ It could be, that this tunable will be replaced by nf_conntrack_tcp_timeout_time_wait in new kernels.

Re: Tomcat Executor MBean
All i am doing is creating an instance of a connector and setting it with an java executor with an custom thread pool. Not sure i get it, when you say registering the executor mbean, thought if connector is just programmatically created, it shouldn't have really mattered. Moreover, it does show the connection count accurately.

Tomcat Executor MBean
Hi, I am using an embedded version of Tomcat 7.0.42. Using java executor with either of the connectors i.e. BIO/NIO. However while monitoring the server via JMX, I see the mbean attributes, currentThreadCount currentThreadsBusy always showing the value "-1". The only one that shows the appropriate dynamic value is connection count, which seems to match the count of the client threads that I initiate. Any idea how to get currentThreadCount and currentThreadsBusy to show the right values? Thanks
difference in behaviour of tomcat 6 and tomcat 7 very imp
Hi,
I have done analysis on static references and found a interesting
point al;so i find a difference in behaviour in tomcat 6 andtomcat 7
I created a class (TestStatic) which has a static reference to VO(java bean)
in my servlet i declared TestStatic as member variable and initialized it
there and i deployed my app and hit my servlet and then undeployed it ... i
used eclipse MAT and saw that both TestStatic and VO objects are not getting
garbage collected
then i changed the code in my servlet and removed TestStatic from member
variable i used spring beanfactory to get TestStatic object in my service
method and repeated step of deploying hitting my servlet and undeploying ..
i used eclipse MAT and saw that only VO object are not getting garbage
collected
so what can be concluded static references are never garbage collected ? or
even objects holding static references are not GC'ed.
In tomcat static refrence are getting garbage collected but in weblogic it
is not can any body help

Hello;
I am running a tomcat 6 webapp using Jersey and I am running into
a concurrency issue. When there are multiple concurrent
connections to tomcat only one or two are processed concurrently.
I have increased the maxThreads on the connector and now can see
the requests being processed by different threads however I
still on observe one or two threads running concurrently.
Example:
Given the following servlet;
Servlet()
{
Output(Start thread);
Thread.sleep(2);
Output(End thread)
}
I would expect the following output
Start Thread
Start Thread
Start Thread
Start Thread
End Thread
End Thread
End Thread
End Thread
Instead I see
Start Thread
Start Thread
End Thread
End Thread
Start Thread
End Thread
Start Thread
End Thread
What are the factors that control thread concurrency in Tomcat?
Has anyone seen behavior like this before? Should I expect a high
number of concurrent threads or does java/tomcat gate access to
the servlet?
Looking at a crystal ball I would guess that your client is a web
browser. A well-behaving browser creates no more than 2
simultaneous connections to the same host (a limitation recommended
by the HTTP specification).
No longer true. Firefox and Chrome default to 6 per server:
http://kb.mozillazine.org/Network.http.max-connections-per-server
http://code.google.com/p/chromium/issues/detail?id=12066
A Tomcat can certainly serve more than 2 clients simultaneously. It
is possible to mis-configure it or create a servlet that serves no
more than 1 client, but you must be creative (in a newbie way) to
do so.
Without seeing your actual configuration and your actual code it
is impossible to provide any review.
If congestion were at Tomcat side, as when several threads are
waiting for the same resource, it would be easy to spot the place
by taking a pair of thread dumps (see wiki - FAQ -
Troubleshooting).
Mark, you should probably print the thread id when doing your
printlns. That will help you see what is going on. Also, you might
want to try making more than 4 connections. What client are you using?

So you have a quick-and-dirty proxy servlet, right?
There are a number of optimizations, etc that you should probably
make, but none of the above code uses any Tomcat code (other than
fetching information from the incoming request, which presumably works
correctly).
It looks like you are getting a 400 from the server your code is
contacting. Have you looked at the request that is actually being sent?
Under what conditions do you get a 400 response? I see you are

I've done this with SOAP REST apps using Spring Web Services Spring MVC. Works great. Do you have a particular framework / set of libraries you're targeting?

It can also *not* be a timeout on the client (browser) side. If there was a timeout on the client side, it would close the connection with the server, and you would never see this message (because the server could not send it to the client, if the connection was closed).

The main intent of this message is : *please help us help you*. Apache is the generic name of at least 30 different software packages sponsored and/or assisted by the Apache Software Foundation. See here : http://projects.apache.org/indexes/alpha.html Among those projects, there exist : - Apache httpd (see http://httpd.apache.org/) - Apache Tomcat (see http://tomcat.apache.org/) Each of those has on-line documentation. Each of those exists in at least 10 currently-used versions. Each of those can run on a variety of hardware and software platforms. Each of those has several configuration files, and several logfiles. Each of those has probably more than 10 different time-out settings, which apply to different things. So when you write apache or apache log or timeout, it does not really mean anything, because it could be one of many possible things. So we have to ask again, and again, to get some real information out of you. This is annoying. On this Apache Tomcat Users's mailing list, there are an average of about 20 messages per day, by people who have a problem and are looking for help. And there are about 10 people who regularly try to help and respond to these messages. These people do this for free, using their own time. They all have a job apart from that, so their time is limited, and they tend to focus on questions which are asked clearly, and which provide clear and precise information that allows to diagnose a problem quickly and allow to provide quick and precise responses. And after a while, they tend to ignore people who do not provide such information, or do not read the answers that they get, or do not respond (or not in a useful way) to the questions asked, or keep repeating the same thing without providing any new information, or look like they are not reading the on-line documentation, or look like they are not really trying themselves to solve their problem and expect someone else to do it all for them; or look like they are not wanting to think by themselves and understand the tools which they are using. Surely, you do not want this (being ignored) to happen to you, do you ? We do not want this to happen either, which is why would you please answer the following questions clearly, for a change ? (And please put the answer below each question, and not all on top of your message. Someone will have to read this, and figure out what is the answer to what question) On what platform does this all run ? (OS and version) (under Linux, the output of uname -a) What is the version of Apache httpd that you are using ? (When you restart Apache httpd, this is written in the first line of the Apache httpd error log file.) What is the version of mod_jk that you are using ? (When you restart Apache httpd, this is also written in the first line of the Apache httpd error log file.) What is the version of Apache tomcat that you are using ? (under Linux, the output of the command (tomcat_dir)/bin/version.sh). What is the version of Java that you are using ? (same thing, or try java -version) Note: some of these answers may not be relevant, in the end, to your problem. But it saves us a lot of time if you provide them right away, because then we can at least eliminate in advance some possible scenarios, or tell you what to run in order to obtain additional information. Next : - when you are mentioning a configuration setting (your timeout e.g.), please indicate clearly where you set this configuration setting (in what file), and copy the line of that file in your message to the list. - when you are mentioning a message from a logfile, please indicate the name and path of that logfile, and copy this entire logfile message in your message to the list, as it appear in the logfile, without interpreting it or cutting pieces out of it. - if you are getting an error somewhere, please indicate clearly when and where this error occurs, without forcing someone here to have to pull it out of you bit by bit over 3 days and 5 message exchanges. If you had done all that, then you would probably already have received a couple of useful answers right away, after your first message to the list, instead of having to read this manual.

Now if you look at your Apache Tomcat logs for the same time period, you may see the cause of the error. In this case, I get a stack trace (because people didn't catch errors correctly in this application), which indicates a null pointer exception. Armed with this information, I can go back to the application developers and tell them to fix their code. You will need to post the relevant portion of the Apache Tomcat logs in order for anyone to have any idea about what's going on. Please post

Re: [OT] timeout
HI All, The problem is solved now . we are have implemented a callback functionality where after every 45 seconds we call back the same method again .Hence making sure that there is no timeout. But as per identifying the actual reason behind the problem i tried to reproduce the issue,after every time after response exceeds 1 min i would get same internal error with same logs as I had mentioned earlier .I got the confirmation that there is firewall between users browser and web-server but i could not get more information about firewall . I have read many blogs where people have faced same issue because of firewall. I had no clue that firewall would drop the connection if it does not recieve response within stiplulated time. Can i increase this timeout period ? if firewall was not there then my app would i worked properly ?

Mostly? Mostly? As in sometimes there's a firewall, and other times there's not, but mostly not? Or do you mean that you're supporting this application at multiple sites, and it's misbehaving at some sites? And that most of the sites do not have a firewall between Apache HTTPD and Apache Tomcat, but some do? Or do you mean that you're almost certain that there is no firewall between Apache HTTPD and Apache Tomcat, but you're not 100% certain? But why would this firewall drop the connection ? Firewalls can be configured to drop connections after a certain amount of inactivity. If you have a long-running process and are not sending information back to the user, there are many places where the connection could be closed. 1. Between Apache Tomcat and Apache HTTPD As I mentioned earlier, if you have configured an AJP timeout (which is not the default configuration) and it is too short, Apache HTTPD will close the connection and send an error message back to the browser. 2. Firewall between Apache Tomcat and Apache HTTPD A firewall can be configured to close connections after a period of inactivity. 3. Firewall between Apache HTTPD and the browser A firewall can be configured to close connections after a period of inactivity. This might generate the type of error in the log extract that you posted earlier. However, that error may be completely unrelated to the problem, as well as all of these other musings many of us are doing. The short answer is that none of us know, because you have not provided enough information for us to be anything more than speculative. If you want help in resolving this problem, you need to provide us with answers to the questions we've asked (as a start). We can then help (mostly by asking more questions) narrow down the possibilities, and then possibly help you solve the problem. Or as André politely pointed out, give you enough information so that you can go back to the developers so that they can fix the problem. As he has pointed out, 90% of the time it's an application issue. There is no 'magic' one line answer and configuration that will fix your problem (most likely - but again, we don't know). If you do not have the answers to the questions we are asking, please go ask someone who does have the answers and the access for the information. Otherwise we're all just wasting time and bandwidth. Meanwhile your users are still getting errors . . . . . . just my (not caffeinated) two cents /mde/ PS - please, please, please do not top-post. Your comments when they're read first make no sense until you scroll to the bottom and read the rest of the message. /mde/ On Mon, Mar 31, 2014 at 3:16 PM, Howard W.

Tomcat Xml parser issue
Hi All, I have application which is using spring , ESAPI and oracle xmlparserv2.jar , this application works fine in my local tomcat on windows but when i deployed in linux server with linux based apache tomcat i got below error when spring container was trying to parse application specific xmls org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanDefinitionStoreException: Parser configuration exception parsing XML from class path resource [spring/spring-context.xml]; nested exception is javax.xml.parsers.ParserConfigurationException: Unable to validate using XSD: Your JAXP provider [oracle.xml.jaxp.JXDocumentBuilderFactory@526ad194] does not support XML Schema. Are you running on Java 1.4 with Apache Crimson? Upgrade to Apache Xerces (or Java 1.5) for full XSD support. when i removed xmlparserv2.jar from my war file the application worked fine , what is the issue is this due to class loading issue or could be possible reason for this issue . Does tomcat provide xml parser which spring loads. -- *Thanks & Regards Vickyb*

Thanks but the same war works fine is WebSphere and tomcat on Windows it is just tomcat provided by Redhat which work different i.e it throws the exception On Nov 16, 2017 11:39 PM, "Christopher Schultz" < ch...@christopherschultz.net> wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA256 > > Vicky, > > On 11/16/17 12:24 PM, Vicky B wrote: > > It is XML parser (DOM and SAX ) from oracle (doc > > <https://docs.oracle.com/cd/B10501_01/appdev.920/a96609/arj_xmlparserv > 2.htm>) > > > > > . > > Why do you need a custom XML parser?

Re: Tomcat Xml parser issue
It is XML parser (DOM and SAX ) from oracle (doc <https://docs.oracle.com/cd/B10501_01/appdev.920/a96609/arj_xmlparserv2.htm>) . Why is tomcat using XMLparserv2 , tomcat we have in linux machine is from redhat . Why does tomcat downloaded from apache tomcat site work different form the one provided by REDHat . how does class loading work in tomcat.
