RE: Re: starting and stopping Tomcat from Java code
Oleg, Have you looked into managing the tomcat instance with MBeans. All you need to do is establish a connection to the other JVM with an MBeanServerConnection instance. This does require a port to be exposed from Tomcat for remote monitoring. But once you have the connection you can do what you want with the remote Tomcat. Just look at how JConsole monitors/manages remote JVM applications for an example. HTH - andy Oleg Lebedev [EMAIL PROTECTED] wrote: Yes, that would work if I had a handle to the embedded instance.

Re: Problem with mod_jk Connector
Good Afternoon Michael The Tomcat ajp connector configuration available at http://tomcat.apache.org/tomcat-3.3-doc/mod_jk-howto.html states that when the attribute forwardAll=true ALL requests go to tomcat to quote the doc a.. forwardAll - If true, forward all requests to Tomcat. This helps ensure that all the behavior configured in the web.xml file functions correctly. If false, let Apache serve static resources. The default is true. Warning: When false, some configuration in the web.xml may not be duplicated in Apache. Review the mod_jk conf file to see what configuration is actually being set in Apache. so in the event that forwardAll=true then all your requests will go to Tomcat then we can look at the tomcat and specifically the connector directives available at http://tomcat.apache.org/connectors-doc/config/apache.html which states JKUnmount takes precedence over JKMount statement and blocks access to the url specified in the JkUnMount directive to quote JkUnmount directive acts as an opposite to JkMount and blocks access to a particular URL. The purpose is to be able to filter out the particular content types from mounted context. The following example mounts /servlet/* context, but all .gif files that belongs to that context are not served. # send all requests ending with /servlet to worker1 JkMount /servlet/* worker1 # do not send requests ending with .gif to worker1 JkUnMount /servlet/*.gif worker1 #JkUnMount takes precedence over JkMount directives, meaning that the JK will first look for unmount and then for mount directives. The following example will #block all .gif files. # do not send requests ending with .gif to worker1 JkUnMount /*.gif worker1 # The .gif files will not be mounted cause JkUnMount takes # precedence over JkMount directive JkMount /servlet/*.gif worker1 To my understanding forwardAll acts as the gatekeeper to tomcat Once tomcat has the request tomcat (and specifically tomcat connectors) directives JKUnMount would then block access to that URL Anyone else ?

Re: URL rewriting best practice?
Kristian
you can write a servlet filter for this. It will be easier that way.
mod_rewrite is one way of doing it , but if you are going to target only
your JSP I would recommend to go to the servlet filter way.
You could also use valves, but you can do almost the same things with
servlet filter.
Example of class is:
public final class URLRewriteFilter implements Filter {
// you have to implement this method
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain)
throws IOException, ServletException {
// you code goes here
chain.doFilter(request, response);
}
}
If you need help implementing it, just let me know.
With Best Regards

Hi all;
currently I'm into deploying a small jsp/servlet based application which
more or less utilizes a dispatcher servlet to provide .jsp-based
content. For that, I'm into using URLs like
http://foobar:8080/Site?path=home/users
to, in example, show the site section home - users. For now, I'd like
to do URL rewriting in order to provide users with an URL like
http://foobar:8080/home/users or maybe
http://foobar:8080/Site/home/users
to see the same content. My initial idea was to use apache, mod_jk and
mod_rewrite to do right this, but don't feel too good about that idea
because sooner or later the site URL will also have to carry around a
session ID and in that I am afraid that URL rewriting will get me into
trouble. So, my question: What is the best way of doing URL rewriting in
such a situation? Does tomcat provide any ways of achieving what I want?
TIA and bye,
Kris

Re: Multilingual usernames and passwords does not works.
If I were you, I'd use Tomcat 5.5. No, I don't know if your i18n problem is related to version, but using the latest version could avoid other not so obvious problems. As mentioned by other, your encType is wrongly used. It's for MIME-TYPE. And you don't need to specify acceptCharset is you're using one encoding for the whole page. OTOH, not all browsers support these attributes. Your problem probably comes from j_security_check. I've never used it, so I'm not sure if it is i18n-aware, or at least utf8-aware. You have to know that data are encoded in UTF-8 during the submission to server. If the server (strictly speaking, the programme specified by the action attribute) thinks it's ISO-8859-1, your data are screwed. So, check the doc on j_security_check to see how to make it read data as UTF-8. HTH Manish Dalakoti wrote: Hi, I'm using form-based authentication.

Re: URL rewriting best practise?
Kristian I forgot to ask if you want the user to see the new URL or not, is this important in your application? If this is the case then you will have to consider looking into the HTTP response codes. Also, do you always plan to have apache in front? If you use IE, you will have to write an ISAPI Filter to duplicate the mod_rewrite functioanlity [you can buy one too] as it doesn't come with IIS. Hope this helps.

implementation difference between Cookie and HttpSession

Re: implementation difference between Cookie and HttpSession
HttpSession expires after the timeout period you set in your servlet conatiner. for example if a user is shopping and leave its PC to go for a walk , when he comes back the session will likely expires. A cookie on the other end can be set to expire later or never, or always. when you track user access, you will have to differentiate both, depends on what you want to achieve. You can set a specific cookie for the trackingn purpose and use apache log format to log it. then use normal weblog analyser. Have a look there for more info: http://webdesign.about.com/cs/loganalysistools/a/aaloganalysis.htm You may have to do log it to a database if you want to cross reference with other things and have nicer reports and better querying facility. For this you can use a Servlet Filter.

Yes it will work that way. The servlet filter process the request it gets from apache the same way it will without it.

Re: URL rewiting best practise?
Hi Kris, I found that I couldn't use mod_rewrite infront of mod_jk on apache. It seems that mod_jk handles matching requests before mod_rewrite, therefore a transformed request never gets the chance to be processed by mod_jk again and a 404 is always thrown. To get around this, I wrote my own (very simple) web application filter which you can download and use as you wish: http://www.axonbirch.com/java/SearchEngineFriendlyFilter.java This means that the java application does the rewriting. It's not terribly efficient, I'm sure many improvements could be made and if you have some feedback or improvements to make, they would be gratefully received. Kind Regards, Chris.

Problem with Context configuration!
Hello Folks:
I am currently upgrading from Tomcat 5.0.28 to 5.5.12.
I have built my application using Jetspeed 1.5 and I am having problems
with Context configuration.
On Tomcat 5.0.28, the servlet mappings work fine! For e.g.,
The URL http://localhost:8080 would automatically resolve to the
jetspeed servlet.
After migration to 5.5.12, I am not able to do the same. But, If I
alter the URL to http://localhost:8080/jetspeed, it works fine!
I know something is screwed up because of some setting and I would
appreciate a fresh pair of eyes helping me on this!
I haven't altered anything related to Tomcat 5.5.12. I downloaded it
and unzipped it.
Exploded my WAR in ${CATALINA_HOME}/webapps/jetspeed. Copied the
jetspeed.xml configuration file to
${CATALINA_HOME}/conf/Catalina/localhost/
Jetspeed.xml
snip
context path=/ docBase=jetspeed debug=0 reloadable=true
crossContext=true
...
...
/context
/snip
Relevant configuration from my application's web.xml is:
snip
.
servlet-mapping
servlet-name
jetspeed
/servlet-name
url-pattern
/portal/*
/url-pattern
/servlet-mapping
servlet-mapping
servlet-name
jetspeed
/servlet-name
url-pattern
/jetspeed/*
/url-pattern
/servlet-mapping
.
/snip
The web.xml under ${CATALINA_HOME}/conf has the following servlet
mapping:
snip
...
servlet-mapping
servlet-namedefault/servlet-name
url-pattern//url-pattern
/servlet-mapping
...
/snip
I also have the manager app which is bundled with Tomcat 5.5.12 and
whose context info does not define the path attribute.
I am not sure if the manager/host-manager app configuration is
interfering with my configuration.
Would appreciate all help in this regard!

RE: ContextManager in Tomcat 5.5?
In summary: 1) Edit the isapi_reg file (part of Tomcat or make your own) to and replace $tomcat_home with the local path (ie. d:\test\t4\webapps\tomCat_webApp_subfolder...) 2) Run that reg file. 3) Create a virtual folder in your root website named tomCat_webApp_subfolder, point it to the tomcat webapp subfolder. Default security. 4) Create a virtual folder named jakarta and point it to the bin directory with the isapi_redirect dll file in it. Give this item execute rights. 5) For 2003 only, add a web service called 'jakarta', set it to allow and point it to the isapi dll above. 6) For 2003 only, add the mime types (.class, .properties, .tmp) to the virtual or web folder. 7) Restart the IIS admin service. As a side note (resolved last week here) for additional servlets under IIS: These are two files located in (or somewhere else if you changed the isapi_redirect reg file) \$TomcatRoot$\WEB-INF\config\jk\iis\ uriworkermap.properties workers.properties In the uriworkermap.properties file you add your custom servlets. In example (/virtualRoot/pathToServlet/servletName/=workerThread): /webapp_subfolder/servlets/yourCustomServlet=$(default.worker) or (for a more generic approach) /webapp_subfolder/servlets/*=main If you were hosting multiple virtual containers all using the same servlets or working in the root containers you would create and edit these two files in the $tomcatHome$\conf\ folder.

RE: Antwort: RE: Tomcat JDBC connection with Mysql
Jan, Tomcat runs just fine on Linux. Use the most recent version (Fedora Core 4 is fine, or OpenSuse 10, or ...). These should come with a fairly recent version of Tomcat (5.x or 5.5.x) or the packages should be available. I prefer to install Tomcat myself on Linux, from a downloaded binary (tar.gz file) as some of the Linux distributions break things up in various ways, that I find a bit confusing (though I can also usually see the logic of it too). However, why in the world would you be developing with Tomcat 4 - it is two major versions behind. If you had an existing production version to support, that would be more understandable. But you are starting out clean it seems - there are many security and performance fixes are in Tomcat 5.5.

Tomcat 5.5.12: Stopping webapp doesn't seem to kill everything?
I'm using Tomcat 5.5.12 on a Linux box. My web application uses a third-party library which opens up a port to listen for incoming connections. What I am confused about is that even after I shut down the web application (via the Stop link on the manager application) the library appears to still be active and the port is held open. Executing 'lsof -i' shows a whole bunch of threads still listening on the port. I am trying to restart my application after it gets into a bad state, but it doesn't appear to be completely terminating. Thanks in advance for any insight. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ContextManager in Tomcat 5.5?
Yes, I've seen those but they are Tomcat 4 docs. Tomcat 5 does have the IISConfig still, but it has been moved to org.apache.jk.config.IISConfig and the javadocs talk of a IISConfig tag that I can't find in Tomcat 5.5 Docs. Are the javadocs wrong, and this class should be configured as a Listener? The current version of the IIS doc (http://tomcat.apache.org/connectors-doc/howto/iis.html) makes no mention of IISConfig, so I'm trying to figure out what the changes were beyond moving the class.

Performance degradation under load
I have a performance issue that I'm having trouble with - perhaps somebody has seen this sort of thing before and can help me out. Problem: Under no load my page responses average about 1.2 seconds (according to jmeter tests), which is pretty good considering the heavy jdbc useage of my applications. However, once I begin to ramp up the load to 30 or 40 consecutive users the performance quickly degrades down to about 4 seconds average response time. While this takes place, the machines are only showing about 5% cpu utilization and have 3.5gb of memory freely available. Network resources also appear to be free. So I definitely don't have a hardware issue, especially considering that there are two balanced machines and neither are showing more than 5% busy. I seem to have a bottle neck somewhere in the system, but am unsure how to track it down. Setup background: This is a new setup that's not in production yet. I'm running Apache 2.05x and Tomcat 5.5x using mod_jk. Apache and Tomcat reside together on both machines (Win 2003), so there should be virtually no latency between them. The machines are balanced on the front end by Coyote Point Equalizers. Tomcat is handling connection pooling to our iSeries database server (db2, jdbc), but I'm not sure it's working correctly because when I do netstat I see several thousand db connections sitting at TIME_WAIT (presumably abandoned and waiting to be cleaned up by the pool manager). This could be one of my problems, but I don't think it's the whole problem and I don't know how to verify. The call to the pool manager is actually coming from the Spring Framework, which possibly has a bug in it, but I suspect instead that Tomcat is not returning the connections to the pool (unless I'm interpreting the existance of so many connections entirely wrong to begin with). I'm also using Tomcat to persist my sessions occasionally (every 2 minutes) to the same iSeries. I see several possible bottle neck points; the http forward from the load balancer to the server machine (very unlikely), the tcp communication between Tomcat and Apache (maybe), the jdbc connections to the iSeries (this is my top suspect at the moment) or some sort of db collusion occuring on the sessions persistance table.

Adjusting Memory
All, One of our customers has recently purchased a Quad Processor Mac OS X (v10.4 Server) for their Tomcat server. The machine has 8 gigabytes of RAM. The application they are running is very large and extremely complex, containing well over 100 pages. They are using Tomcat v5.5.7. The JVM is version 1.4.2. I need a bit of assistance with how to set the Java OPTS so that the memory is fully optimized and all processors are used. I have done some reading, but the advice is, honestly, all over the map. My current settings are: JAVA_OPTS=-Djava.awt.headless=true -XX:+UseParallelGC -Xms512m - Xmx2048m -server Using Apple's Activity Monitor, the maximum amount of 'real' memory I could see was 700 megabytes; while the maximum amount of virtual memory was 2.3 gigs. In fact, once I reached 700 megabytes of 'real' memory, the 'out of memory' error was returned. Thank you in advance.

Re: Fw: Performance degradation under load
Agreed. We are doing quite a bit of database access per app call though - we run JD Edwards OneWorld on the backend and our web apps are using those tables entirely. JDE wasn't exactly created on the premise of efficiency - it's made entirely for flexability, which (in my mind) is the exact opposite of efficiency. That means that there are a real lot of tables and that each call to the web app will cause many table accesses at once. When I kill all db connections and start with a clean slate, I can hit the web app one time (just log in) and see 5 new connections start up. Well guess what? In order to build a user session I need to read from 5 db tables. When I move to another screen, I also see the same number of connections open up as there are tables to be read from that app. I do believe that I'm opening one connection per table, doing a single read and then abandoning the connection. But I was under the impression that Tomcat's pool manager would calm this effect a bit, though it doesn't appear to be helping at all. You can see that if you have a really heavy database and that if you are opening one connection per table per app read (per user) and have 30 or 40 users pounding away simutaneously, you would end up with a whole lot of open connections really quick. But my servers have more than enough cpu capacity to deal with cleaning up the open connections and my iSeries is a monster - I couldn't make the cpu's even blink if I tried (and it has 6 active gygabit ports, so I'm not worried about tying up ethernet). So, while I'm sure this isn't ideal chat behaviour between two machines, I don't really know that it is what is causing my performance issue. I think I'll need to solve this particular problem, and perhaps when I do I'll have licked my degradation issue as well, but I'm not really sure where to begin with either at the moment. -marc --- Peter Lin [EMAIL PROTECTED] wrote: under normal conditions, a single webserver shouldn't have several thousand DB connections. that seems a bit odd to me. peter lin On 12/15/05, Martin Gainty [EMAIL PROTECTED] wrote: Marc- what types of Coyote Point Equalizers are you using?

Re: Performance degradation under load
While you are running how many database connections does your database report having open? You might want to use the tomcat manager status app to see how many threads you are using, how many sessions are being created, etc. Lots of sessions can eat up memory as well if they are not being killed off quickly enough. If you have lots of threads coming in, make sure to set your maxThreads and associated parameters to handle the load. Also check your queue depth, once the queue fills up no more requests are going to come thru. Is your database reporting any core dumps, or alerts, or deadlocks?

RE: Performance degradation under load
From: Marc Richards [EMAIL PROTECTED] Subject: Performance degradation under load Tomcat is handling connection pooling to our iSeries database server (db2, jdbc), but I'm not sure it's working correctly because when I do netstat I see several thousand db connections sitting at TIME_WAIT (presumably abandoned and waiting to be cleaned up by the pool manager). This really sounds like you're not using connection pooling, but instead are opening a new connection for each request. How many do you have configured in the pool? If it's less than the number you see with netstat, that would be another indication that your app is getting its own connections rather than ones from the pool. Is your app closing the connections (and statements and result sets) properly?

Re: Performance degradation under load
sounds like you have a big big mainframe, so I also doubt the database server is an issue. Is there any firewall between tomcat and the database server? it could be the firewall is limiting the number of connections and therefore forcing the db connection pool to wait longer than it should to create a new connection. beyond that, about the only way would be to start tomcat using a profiler and see exactly what is blocking. peter On 12/15/05, Marc Richards [EMAIL PROTECTED] wrote: No, the db is actually our world-wide enterprise server.

RE: Performance degradation under load
Yes, I agree - I thought that too, but didn't really know what I was suppose to be seeing. I have Tomcat configured to open 500 (because I was mucking around trying to make it work, not because I think that's the right setting) connections on startup and maintain a minimum of 100 idle at any time. But when I start Tomcat I only see a single ESTABLISHED connection to the db. Then I start jmeter and this list explodes. I thought I might be bypassing the connection pool too, but didn't know how to check that either. We use the Spring Framework and it has a method for calling the JNDI pool manager. So you just configure Spring to obtain new connections from Tomcat and it does the actual access to the db when an sql is used. The apps never actually close any connections because Spring is suppose to do that for you too. There just doesn't seem to be a way to check that everything is being done correctly (that I can tell). I can tell you this though - when I changed the Spring configuration initially, I forgot to save my changes to the Tomcat config. Immediately all database connections from the apps began to fail because the pool manager wasn't turned on. Then I configured Tomcat and checked in my changes - it began working again. So I can tell that Spring is relying on Tomcat's ability to connect to the db, but I can't tell that it's using it correctly. It seems to me that Spring is using JNDI to obtain a connection, doing a read and then leaving the line for dead. The first 500 get used up and then either Tomcat or the apps themselves begin firing off more. Here is a question I probably should have asked first: When I configure Tomcat to pool connections (let's say to start up with an initial 50), what should I see when I run netstat directly after starting Tomcat and before I make any calls to the web app? Should I see 50 connections (I don't)? -marc --- Caldarale, Charles R [EMAIL PROTECTED] wrote: From: Marc Richards [EMAIL PROTECTED] Subject: Performance degradation under load Tomcat is handling connection pooling to our iSeries database server (db2, jdbc), but I'm not sure it's working correctly because when I do netstat I see several thousand db connections sitting at TIME_WAIT (presumably abandoned and waiting to be cleaned up by the pool manager).

It seems that this occurs because Tomcat stops answering requests on port 8080 (the Apache-Axis diagnostic web page (http://127.0.0.1:8080/axis) becomes unavailable). After examining the Tomcat log files the only suspicious entries we found was this exception that occurs regularly: 2005-12-12 12:47:04 StandardManager[/axis] Session event listener threw exception java.lang.IllegalStateException: getAttribute: Session already invalidated at org.apache.catalina.session.StandardSession.getAttribute(StandardSession.java: 953) at org.apache.catalina.session.StandardSessionFacade.getAttribute(StandardSession Facade.java:171) at org.apache.axis.transport.http.AxisHTTPSessionListener.destroySession(AxisHTTP SessionListener.java:43) at org.apache.axis.transport.http.AxisHTTPSessionListener.sessionDestroyed(AxisHT TPSessionListener.java:72) at org.apache.catalina.session.StandardSession.expire(StandardSession.java:658) at org.apache.catalina.session.StandardSession.expire(StandardSession.java:607) at org.apache.catalina.session.StandardManager.processExpires(StandardManager.jav a:793) at org.apache.catalina.session.StandardManager.run(StandardManager.java:870) at java.lang.Thread.run(Thread.java:534) It looks like Catalina tries to call getAttribute on a session it has already destroyed. Can this bring Tomcat to stop answering requests. Since the exception says that the session is already invalidated I would believe that the session is indeed destroyed. If not, could this cause a starving of free sessions, and thus bring Tomcat to a halt? I have seen some posts proposing to use: export LD_ASSUME_KERNEL=2.x.x Can that be a solution? As stated above we use RedHat 9.0 with kernel 2.4.27 what kernel version should we use in the export?
