Re: CPU usage with APR and connectionTimeout impact
Funny, according to the documentation there exists no connectionTimeout attribute for the apr connector. Setting the value to '0' could mean all sorts of behavior, no way to know for sure short of checking the code. (it could mean the connector will not wait for the uri line at all) I can't comment about a correct value for your application. Setting it to a low value will have the connector thread return to the pool faster on connections where the peer has gone to lunch after the initial connection. This only matters if you have a large number of such peers. I'm sure one of the veterans here can clear this up for you. Hello, In my project, we are using Tomcat 6.0.18, with APR 1.2.12 and tc native 1.1.14 on an Redhat OS (Linux kernel 2.6.18). There is a behavior that I can't explain: -with connectionTimeout=0, the process tomcat uses a huge percentage of CPU, even if there is no traffic. but we doesn't observe any problem and the response time is good. -with connectionTimeout=5000, the process tomcat uses a normal percentage of CPU, when there is no traffic. -without APR and with connectionTimeout=0, the process tomcat uses a normal percentage of CPU when there is no traffic. After different searches on the web, tomcat manual and mailing lists, I don't find the reason of the link between CPU usage and connectionTimeout/keepAliveTimeout with APR. With the previous release of Tomcat (5.5) and APR, we have a similar CPU usage (without traffic, high CPU load) and when we modify another parameter (firstReadTimeout), the behavior also changes in the same way. I know there is no real trouble, but I'm curious and prudent: I don't like to do something, when I don't understand what is hidden behind.

Setting the value to 0 means no timeout (according to some mail exchange I found in tomcat mailing list). No timeout is default value of this attribute.

Re: CPU usage with APR and connectionTimeout impact
You're right. I missed it. APR has the same attributes as the HTTP connector. I think a seperate overview of attributes per connector would be clearer. The HTTP connectionTimeout description states: - The number of milliseconds this *Connector* will wait, after accepting a connection, for the request URI line to be presented. The default value is 6 (i.e. 60 seconds). '0' is not explicitly defined as a special value. According to the description it would mean a wait period of 0 milliseconds for the uri to be presented. This would make the connector practically useless.

Why doesn't tomcat log a stack trace
It does, in the log associated with the Host of interest:
Yup, although Chuck's example is a missing filter, not a missing
listener. The code is right here, in StandardContext.listenerStart:
try {
Class clazz = loader.loadClass(listeners[i]);
results[i] = clazz.newInstance();
// Annotation processing
if (!getIgnoreAnnotations()) {
getAnnotationProcessor().processAnnotations(results[i]);
getAnnotationProcessor().postConstruct(results[i]);
}
} catch (Throwable t) {
getLogger().error
(sm.getString(standardContext.applicationListener,
listeners[i]), t);
ok = false;
}
If the class wasn't found, it'll be logged here, and listenerStart
returns false. Given the behavior of listenerStart, it could probably
just propagate the exception instead of starting-up all the listeners,
then failing to load the entire application. That would allow
StandardContext.start() to give you a single error message /including/ a
stack trace.

Re: How2 Disable PUT response in OPTIONS method
Thanks markt-2. The idea of using a ServletFilter is a good one but will not work because the application (we've inherited) does not have a single entry point (dispatch/front-controller) yuck.

Re: How to debug Error: listenerStart?
How are you running Tomcat? IDEs (e.g. Eclipse) often reset the logging if you start Tomcat inside the IDE; For me, using the MyEclipse plugin in Eclipse completely suppresses everything but catalina.out. If I need the other logs, I start Tomcat from its ~bin/ startup.sh (I have a vanilla download from the Apache site).

Session Replication in Cluster
Hello all, I've built a very simple 2-member Tomcat cluster for testing, but I am unable to get the session replication quite right. The problem is when I fail one member of the cluster. The behavior I was expecting is that the other cluster member would take over the session ids for the failed member. However it is appending it's own jvmRoute value to the session id, and thus setting a new cookie. Details: I have 2 cluster members, itchy and scratchy, running on the same physical server, and CATALINA_BASE is /var/tomcat/itchy and /var/tomcat/scratchy respectively. Tomcat 6.0.18 binaries, etc. are at /usr/local/tomcat. Using mod_jk 1.2.27 on Apache 2.2.11 (Apache is also on the same server). I am using sticky sessions. Here are the access logs for the 2 members from a short failover experiment (note I'm including the session ID in the 2nd field). The session starts on scratchy. From scratchy_access_log.2009-04-02.txt: 192.168.200.177 E5BF3FFA9AEE1E3AB0DD4A96BA5E4011.scratchy - [02/Apr/2009:10:19:55 -0400] GET / HTTP/1.1 200 14612 192.168.200.177 E5BF3FFA9AEE1E3AB0DD4A96BA5E4011.scratchy - [02/Apr/2009:10:20:14 -0400] GET /about/ HTTP/1.1 200 19507 At 10:21:39 AM I do a kill -9 on the scratchy instance. Now the traffic goes to the other cluster member as expected. From itchy_access_log.2009-04-02.txt: 192.168.200.177 E5BF3FFA9AEE1E3AB0DD4A96BA5E4011.itchy - [02/Apr/2009:10:22:11 -0400] GET /about/publications/ HTTP/1.1 200 18263 192.168.200.177 E5BF3FFA9AEE1E3AB0DD4A96BA5E4011.itchy - [02/Apr/2009:10:22:32 -0400] GET /about/changes/ HTTP/1.1 200 12736 Note however that the new member's jvmRoute value is now appended to the session id.

I think the reason Xerces works within the application's ClassLoader is because of the backward way that webapp ClassLoaders work (load local before parent). When Xerces is/is not available to the boot classloader as well as the main classloader, that's when problems occur (which is why you need to bundle the parser with Tomcat 5.5 on a 1.4-level JVM). Note that the Tomcat 5.5 compatibility package for running with a 1.4 JRE consists primarily of the Xerces implementation and XML API definition jars, which are built-in to 1.5; leaving the compatibility package installed when switching from a 1.4 to a 1.5 JRE definitely does cause problems.

How to produce a Comet EventType.READ from the clint side?
Hello,
Recently I started to develop a web application
that is based on the Comet Architecture. After a lot of research, I realize
that there is a lack of documentation and tutorials about how to build simple
Comet
applications on Tomcat. The tomcat Advanced IO documentation previews the way
that the server handles the incoming different type events, but doesn’t explain
how to produce these events from the client side (ex. IE, Firefox). The snippet
below produces such an event.
function newConnection(){
xhr = new XMLHttpRequest();
xhr.open('GET','/comet' ,true);
xhr.send(null);
}
When I execute this function, a new event (EventType.Begin)
arrives on the CometServlet.
I am wondering if there is way to produce an (EventType.READ)
event from the client side.
The only way to produce (EventType.READ) events
on the CometServlet was by the above java code, but I don’t know how to use it
efficiently
to accomplish my goal.
Any suggestion?

Re: How to debug Error: listenerStart?
What are you using on the command line to start Tomcat? In particular, what
is the value of the following system properties?
java.util.logging.manager
java.util.logging.config.file
The default values are org.apache.juli.ClassLoaderLogManager and
${catalina.base}/conf/logging.properties, respectively.
- Chuck
I'm using the catalina.sh script that comes with tomcat, with the
following modifications.
I set JRE_HOME to the path of the JRE that I want tomcat to use.
I set JAVA_OPTS with a bunch of memory / garbage collector options.
Both of these variables are hard coded into the top of the catalina.sh
script. The rest is untouched from stock.
I added an echo to the catalina.sh script to print the JAVA_OPTS that
is actually using:
-server -Xss250k -Xms1200m -Xmx1200m -XX:MaxPermSize=128m
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC

-Djava.awt.headless=true
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=/opt/foo/tomcat/conf/logging.properties
The logging properties appear to match what you expect.

Hi,
I've been having issues with tomcat session replication. I have a number
of tomcat servers running in a cluster mode, behind an Apache load

I can set the charset to shift-js in the META tag but it doesn't mean the page is actually in Japanese. I don't see your point Setting charset/encoding is to specify computerized information. It's not just a matter of language. If setting charset in META tag doesn't mean anything to you, the same argument applies to setting charset in HTTP header. And what if another encoding is specified in HTML header, say ISO-8859-1? Which one would the browser use in priority? Nobody knows the answer! Actually, everybody knows the answer, because it's published in the HTML specification: http://www.w3.org/TR/html4/charset.html#h-5.2.2 To sum up, conforming user agents must observe the following priorities when determining a document's character encoding (from highest priority to lowest): 1. An HTTP charset parameter in a Content-Type field. 2. A META declaration with http-equiv set to Content-Type and a value set for charset. 3. The charset attribute set on an element that designates an external resource. Yes, yes, but this is the theoretical answer. Not in practice. When there's a bug, there's a bug. That's why I specify the encoding in both places. While it's not a terrible idea to specify the encoding in both places, you should consider the possibility that the META tag can be wrong. It's not only not a terrible idea, but a good habit to do so. Just like the principle of double check: what's the point of double check if everything works as expected? We do double check because in practice we are subject to errors. A good programmer should never leave anything to chance, that's why it's good to set charset in both HTTP header as well as in HTML header. 2. To make things easier for myself, I always save JSP files in UTF-8 encoding, and I always put this header as well: %@ page pageEncoding=utf-8 % Now everything's in UTF8 from A to Z. If you're following guidelines for i18n, you'll put your non-ASCII strings into property files and won't have to worry about the encoding of the JSP source file. Yes, but again, you're talking in theoretical viewpoint. What about if I want to create a small, quick and short JSP just for some tests? I won't go into changing everything. The simpler is to change one thing: my JSP file. Another situation: what if you don't have total access to all files? Well, if Tomcat is in your computer, it's taken as granted that you could do everything. But what about you're developping a JSP site and have it hosted in some Internet servers? Are you sure you still have all access? And as your link to HTTP recommendation says, some server might not send HTTP header. You'd better also set the charset in HTML header. One more example: you're doing the test in one JSP file in your corner. Everything works perfectly. Then you move the file to another server. In this situation, it's better to have the file self-contained. String sUTF8 = new String(sWrongEncoding.getBytes(iso-8859-1), UTF8); I think that should be rightString, not sUTF8, since the String object has no inherent encoding. Not true. Java string is inherently using UTF-16. If you're so picky on the name, you'd better call it latin1StringConvertedBackToUTF8BeforeConvertedBackToUTF16 but this is getting ridiculous
Re: How to debug Error: listenerStart?
I got a brand new copy of tomcat 5.5.25, and tested it. Some of the provided apps, such as balancer - create entries in the localhost log file. I used kdiff to compare the entire tomcat folder hierarchy to my tomcat distribution, and I can't find any significant difference that could cause my missing logs. I tried adding a missing listener to the balancer app. The error was properly logged. I tried deploying my war file (with a purposely broken listener) to the newly extracted, completely stock tomcat, and I see the same behaviour. No entries whatsoever in the localhost log file from my application, which failed to deploy. So, it would appear that something in my application - where I use log4j - is perhaps preventing the error from being logged by tomcat. What would be doing this? Something in my app is preventing this severe error from being passed up to tomcat to be logged - but then my app doesn't log it either - probably because it is stopped before it ever finishes deploying. There is obviously some interaction going on between my webapp and tomcat's logging system that I don't know about.

See, the parser needs to know about the encoding /in advance/ to be able to read the encoding from said stream. See the point? Actually, it's a good practice to put the encoding, but that's about it, and same goes for a META-TAG. Talking web, the only thing a parser can rely on is a HTTP-Header. And it's getting really nuts, when it comes to UTF-8: Talking about UTF-8 with or without BOM? Even the specs are not clear about that. In my oppinion, the whole character-set is a pain in the ass: I personally wish IETF came up with some specs saying something like the first n bytes of any stream have to be encoded in ASCII containg length and encoding-type of the rest of the stream. I put that on my whishlist for xmas.

From: Christopher Schultz [mailto:ch...@christopherschultz.net] Subject: Re: Tomcat error: It is not available the ServletAction I think the reason Xerces works within the application's ClassLoader is because of the backward way that webapp ClassLoaders work (load local before parent). If you don't mind pursuing this a bit more, I still have some concerns about how this can work reliably. Let's focus on the xml-apis.jar for now, which contains numerous classes that are also in the 1.5 and newer JREs. It would seem that if a webapp had its own copy of xml-apis.jar, it would load some javax.xml.* classes from there, while references in Tomcat's lib directory (including any shared jars used by multiple webapps) would resolve those classes from rt.jar. Constructs like instanceof would fail, since they have different classloaders.

And even further into the black magic of logging configuration within tomcat...
So, after my long thread to figure out the missing stack traces from a bad listener configuration, I _thought_ I knew what I needed to correct. It seemed that Tomcat was trying to use log4j shipped with my webapp, before my webapp had configured log4j. Supplying a log4.properties file in the WEB-INF\classes folder with a temporary log4j configuration seemed to fix the problem. Until... I deployed two webapps within tomcat. The second (and subsequent) webapps _still_ have the problem of trying to log to a log4j which isn't configured - resulting in all error messages being lost. I turned on log4j debugging (-Dlog4j.debug=true) - and here is what I see as tomcat starts: INFO: Starting service Catalina Apr 2, 2009 5:01:22 PM org.apache.catalina.core.StandardEngine start INFO: Starting Servlet Engine: Apache Tomcat/5.5.25 Apr 2, 2009 5:01:22 PM org.apache.catalina.core.StandardHost start INFO: XML validation disabled log4j: Trying to find [log4j.xml] using context classloader WebappClassLoader delegate: false repositories: /WEB-INF/classes/ -- Parent Classloader: org.apache.catalina.loader.standardclassloa...@17200b4 . log4j: Trying to find [log4j.xml] using WebappClassLoader delegate: false repositories: /WEB-INF/classes/ -- Parent Classloader: org.apache.catalina.loader.standardclassloa...@17200b4 class loader. log4j: Trying to find [log4j.xml] using ClassLoader.getSystemResource(). log4j: Trying to find [log4j.properties] using context classloader WebappClassLoader delegate: false repositories: /WEB-INF/classes/ -- Parent Classloader: org.apache.catalina.loader.standardclassloa...@17200b4 . log4j: Using URL [file:/opt/foo/tomcat/webapps/app1/WEB-INF/classes/log4j.properties] for automatic log4j configuration. log4j: Reading configuration from URL file:/opt/foo/tomcat/webapps/app1/WEB-INF/classes/log4j.properties log4j: Parsing for [root] with value=[WARN, Console]. snip log4j: Finished configuring. And then I see output that lets me know that my dynamic configuration of log4j has occurred. Everything is good so far. No warnings have been shown. Now, tomcat starts the second webapp - this is all that I see: log4j:WARN No appenders could be found for logger (org.apache.commons.digester.Digester.sax). log4j:WARN Please initialize the log4j system properly. And then it lets me know that it has finished my dynamic log4j configuration. So, why didn't log4j try to find the log4j.properties file for the second webapp? I'm certainly no guru of how the visibility works between the webapps and their various classloaders - buy why is log4j in the second webapp deciding not to configure itself? And sure enough, if I break the listener in the web.xml for the second webapp, the stack trace is lost. There is definitely a bug here, but I don't know if the bug is in Tomcat or in Log4j.

You could try -verbose:class to see where classes are being loaded from, if you want to wade through a whole lot of output. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

ROOT options
I've been utilizing the device of renaming myapp.war to ROOT.war in order make myapp perform as the default application at http://mydomain.com . However, I thought that earlier this week (maybe last week?), Chuck made a comment that this was the easiest of the options. I'm wondering if I could get some pointers to reading about what these options are. My searches haven't turned up anything.

I go and recompile HelloWorldExample
javac HelloWorldExample.java
That's not sufficient to compile a servlet. You will also need a -cp argument
to inform the compiler where servlet-api.jar is located. If you attempt to do
this via the CLASSPATH environment variable - don't. Using the CLASSPATH
variable is a major cause of classloading confusion and difficult to diagnose
problems. If you have CLASSPATH defined, get rid of it before doing anything
else, and smack yourself if you ever feel tempted to use it again.
When your current directory is
${catalina.base}/webapps/examples/WEB-INF/classes, your javac line should look
like this:
javac -cp ../../../../lib/servlet-api.jar HelloWorldExample.java
Sure enough log shows
0:0:0:0:0:0:0:1%0 - - [02/Apr/2009:15:48:58 -0400] GET
/examples/servlets/servlet/HelloWorldExample HTTP/1.1 404 952
I've done the same thing on my 6.0.18 installation, and it works fine. Do you
have a JAVA_HOME or JRE_HOME environment variable set? If so, what's the value?
You should also be able to find additional information in the logs, including a
possible stack trace of the underlying problem.
There has never been an examples/servlets/servlet directory...
Don't confuse URL paths with file system paths - they're independent. If you
look in webapps/examples/WEB-INF/web.xml, you'll see a servlet mapping for
/servlets/servlet/HelloWorldExample that targets the servlet named
HelloWorldExample, which is configured to use the HelloWorldExample.class.

RE: ROOT options
From: Ken Bowen [mailto:kbo...@als.com] Subject: ROOT options I'm wondering if I could get some pointers to reading about what these options are. You can place a Context element in server.xml, but that is strongly discouraged these days, and we will likely yell at you if you do so. You can also specify the default webapp by creating the file conf/Catalina/[host]/ROOT.xml that contains a Context element with a docBase attribute that points to a location *outside* of the Host appBase directory. You must also remove any ROOT.war file or ROOT directory from the Host appBase. If you want to have the name of your .war file be different from the webapp name, this is the way to do it.
