Cluster JMX objects
Does anyone have any code that shows the use of JMX to monitor the cluster objects in a Tomcat cluster (5.5.17 or later). I am interested in knowing which servers are currently connected, and if any are down. This last I guess is going to have to be done by exclusion as I am not aware of a list of expected servers anywhere.

Odd problem with Tomcat 5.5.9 and PhantomReferences
I have a servlet which I am trying to run under Tomcat 5.5.9 which has a background thread in it. This thread uses JDBC, and in particular the Postgresql JDBC driver. This driver uses PhantomReferences in order to tidy up the underlying C objects. But when it comes to use the PhantomReference it gets:- at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1221) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1181) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at org.postgresql.core.v3.QueryExecutorImpl.registerParsedQuery(QueryExecutorImpl.java:1092) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1177) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:188) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:430) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:346) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:250) The line in registerParsedQuery that is failing is:- PhantomReference cleanupRef = new PhantomReference(query, parsedQueryCleanupQueue); This should work on any JDK since Java 1.2. I am running this with the Sun 1.5 SDK. Is this a sandbox problem? If so what do I need to set in order to allow this to work? Anyone got any idea why this might be failing?

There are two functions (start and stop) which appear to initialise things and tidy them up, and an internal variable which says whether start has been called (and stop not). This should throw a state exception, but somehow this is becoming a ThreadDeath. Now this loader works perfectly well if I do things in servlet methods, but as soon as I try to use the loader in the background thread, or rather as soon the system trys to use it under the covers to load PhantomReference, it fails. The upshot of this problem is that the Postgresql Jdbc3 driver is unusable on a background thread in Tomcat 5.5.9.

Enabling JMX and jconsole in Tomcat 5.5
I am trying to get jconsole to talk to Tomcat 5.5, and failing dismally. My first attempt was to enable the local access to JMX, using just -Dcom.sun.management.jmxremote but when I then start jconsole there are NO local services shown. So then I tried remote access, by setting -Dc.s.m.j.port=9000 and .authenticate=false and .ssl=false, but when I try to connect I just get a connection failed reply. I am obviously failing to do something really basic, but I can not see it. All the howtos just assume it works. Anyone got any clues?

Is anyone here using ha-jdbc with database clusters?
I am trying to set up ha-jdbc, and tried asking quesions on their mailing list but it seems to be a dead list, no traffic for >24 hours apart from my questions. I have it talking from one tomcat to multiple DBs, but I need to set it up using the tag to have these same DBs access from across a Tomcat Cluster. My problem comes when I bring up the second tomcat and it complains that the resource (the cluster) already exists, which of course it does on the first tomcat, but as the cluster is distibutable it should join the existing set rather than trying to create a new one.

How to embed server hostname in JSP page on clustered Tomcat
I have a cluster of (currently) two Tomcat 5.5.17 instances. I want to put a hidden field on the pages which tells me which machine I am currently connected to. Reading the spec it appeared that using:- should work, but it would appear that all this does is take the server portion of the URL. Anyone know how to do this (short of writing some Java code that is, I would rather use simple JSP and JSTL).

filtering tomcat logging using default logging configuration
I have a web application which is using a library which is generating too many messages. These are routed to catalina.out and all come from a particular producer (org.jgroups. is the prefix). I do not want to rework the logging to use log4j or the like, but I would like to suppress these WARN messages for this prefix. I guess I need to modify $TOMCAT_HOME/conf/logging.properties, but what do I need to add? I have read the Tomcat 5.5 logging page, but I am none the wiser as that does not seem to give any examples of filtering non-Tomcat messages.

Is there any documentation of JULI anywhere?
I am trying to work out how to tailor the log entries going into the Catalina log files, and am having no luck at all. I am using Tomcat 5.5.17. I have looked around for documentation of JULI, but I can find nothing which makes sense. There is a comment at the end of the logging,properties file which says there should be a example of exactly the type I want. It says:- # For example, set the com.xyz.foo logger to only log SEVERE # messages: #org.apache.catalina.startup.ContextConfig.level = FINE #org.apache.catalina.startup.HostConfig.level = FINE #org.apache.catalina.session.ManagerBase.level = FINE but as you can see this never mentions SEVERE in the sample lines, only FINE. Also it does not mention com.xyz.foo in the sample lines. There was a mention that Google found that said that there was some documentation in the JULI source, but I do not know where in the Tomcat source tree JULI is to be found, and there is an awful lot to search. Please, does anyone know how to do this, it is causing me real grief.

Well I have made a little progress, but I do not understand what
it going on.
Putting the lines:-
org.jgroups.level = ERROR
org.jgroups.handlers = 1catalina.org.apache.juli.FileHandler
into logging.properties (you need both) has the effect of stopping
the messages going onto the Console (which is redirected to
Catalina.out) but does NOT change what goes to the
catalina.{date}.log files. As I said the handler was the file
handler (which is what generates catalina.{date}.log) and
not to the ConsoleHandler (which sends the output to
catalina.out) I am completely confused.
How is it that something as important as the logging for
Tomcat is so badly documented?

Location for libraries need for resources in Context.xml
With Tomcat 5.5 you can now define things like JDBC DataSources in META-INF/context.xml in your war files. JDBC DataSources need drivers, and obviously they can still be stored in common/lib, but given that they are defined, or rather their use is requested, through the war file, can the drivers also be put in the war file? The same question would then apply to other resources like beans etc. Putting the files in the war would have the effect of making the application self contained, so would there be any downsides to allowing this if it is currently not allowed?

How to tune JSP performance?
I have a system with two identical machines running Tomcat 5.5.17 running identical applications. There are some extra things running on one of the machines, but these problems occur even when they are turned off. The application consists of two parts. There is a JSP layer, and a servlet (handling XML requests). The JSP lay talks to the XML Servlet layer for all requests, the XML servlet layer talks to a Postgresql DB on another machine. The XML portions of this app are running almost identically (i.e. within measurement tolerance) at the same speed, if I send a null request to the XML servlet they respond quickly (including loading and executing the sending routing both response within .20x seconds (the x varies from test run to test run). But using wget to invoke the JSP code gets back the logon page almost instantly on one machine, and takes an age on the other. Actually to find out that it needs to go to the logon page the JSP does not need to use the XML servlet. On the slow machine it takes 30 seconds to send back the 302 rewriting the URL so that it has a jsessionid, and then 16 seconds to serve the HTML for the logon page. On the fast machine it takes less than a second to do the same sequence. Both machines seem to be using <10% of the machine CPU. There is more than enough memory and no shortage of disk space. Both machines are connected to the postgresql machine by TCP/IP and actually the slower machine has a slightly better ping time than the fast machine, but like the XML servlet transactions the difference is within the margin of error. Until this morning both machines were behaving the same, one was probably slightly slower than the other due to the extra things running on it, but you had to be watching quite closely to notice the difference. There does not seem to have been any changes to the system that correspond with this change. Although slightly more traffic seems to be going through it that yesterday, although less than before Christmas when this slowdown was not noticable. The two machines sit behind a load balancer, which is run by the hosting organisation, they deny any changes and this effect is measured on each machine sending the requests to localhost so it does not seem likely to be part of the problem. The machines are running linux 2.6.16. They are behind a solid firewall, and there is nothing that would appear to be doing anything odd on either system, no connected sockets to strange places, no strange binaries or processes. Only the required services are open to the outside world. Also the fact that the XML Servlet seems to be running as normal suggests that the problem is localised to the JSP processing. There are no messages either in the tomcat logs or the system logs that talk of errors at either the hardware or software level. The JSPs are precompiled (by Eclipse) and the WAR files have not changed recently (they are both identical). Anyone got any good ideas as to how I might go about diagnosing this? Are there any good values available anywhere which would tell me where the tomcat system is hitting a bottleneck.

DNS configs are the same on both machines, and on both machines if I type ping bbc.co.uk I get a header line with the IP address back instantly on both machines. Currently it looks to me as though the problem is with the multicast messages for the clustering. I found a timeout message which is suggesting that for some reason although the slow machine can send messages to the fast, the slow machine never gets a reply.

mixed html and jsp site using ProxyPass
I have a site which is a mixture of html (and a bunch of images and flash and other such stuff which came in from the web designer) and a couple of JSPs. I have implemented this with Apache 2.2 and Tomcat 5.5, using ProxyPass statements with ajp in the Location tag. My location block looks like: # it is the root application ProxyPass ajp://127.0.0.1:8009/jsp ProxyPassReverse http://...domain... SetOutputFilter proxy-html ProxyHTMLURLMap http://127.0.0.1:8180 http://...domain... ProxyHTMLURLMAP / http://...domain... So the base stuff is at the root, and the jsp stuff is all under the jsp path element, so index.jsp is at jsp/index.jsp when referenced in a URL. There are some bits of the the Apache managed stuff (css files etc) that I need to reference in the JSP, so those are referenced as /style.css rather than style.css in the jsp pages. It would however be easier if I have the jsp code at the same level (from a URL path point of view) as the html etc files. Is there a way to divert just the .jsp files? I tried but that did not seem to work - maybe I got something else wrong. I have tried looking around with Google, but obviously I asked the wrong question as I did not find a useful answer. Any help gratefullly received. David - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

problem with JSP/JSTL and Tomcat 6
I have some old JSP pages which used to run on Tomcat 5.5. I tried to move to Tomcat 6 and the current JSTL but I am getting some odd errors. When I include the <%@ taglib directives inline in the source, say:- ... <%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %> ... I get an error saying:- The content of elements must consist of well-formed character data or markup. If I put the taglib directives in an include file, I get an error saying that the is not bound. I have the jstl and el files from dev.java.net, and I have tomcat 6 as installed by Debian. Eclipse (Helios with its validation) seems to think everything is OK, but when I used jasper2 to compile it under ant, or simply run the page, I get the errors.

That was the problem. Eclipse had set the new jsp file up with all manner of XMLness at the start (which I had ignored). Getting rid of it and going back to the old HTMLness fixed the problem.

Well the validate routine seems to exhibit the bug.
private boolean validateURLPattern(String urlPattern) {
if (urlPattern == null)
return (false);
if (urlPattern.indexOf('\n') >= 0 || urlPattern.indexOf('\r') >= 0) {
return (false);
}
if (urlPattern.startsWith("*.")) {
if (urlPattern.indexOf('/') < 0) {
checkUnusualURLPattern(urlPattern);
return (true);
} else
return (false);
}
if ( (urlPattern.startsWith("/")) &&
(urlPattern.indexOf("*.") < 0)) {
checkUnusualURLPattern(urlPattern);
return (true);
} else
return (false);
}
seems to me not to allow for anything without either a leading / or
a *. checkUnusualURLPattern does not help either.

Just changing it to a wildcard fixed it. The only thing I changed was the
tag, from "page.htm" to "*.htm".

As Tomcat was throwing exceptions when it loaded the web.xml
I doubt the any other component could cause it. But no, no other
components, raw Tomat.
