Re: newbei
You put the struts.jar and related files in WEB-INF\lib directory of
your application ?. Added mapping in web.xml for ActionServlet ?.
Better you you use Struts blank application which is bundled with
Struts download.

OutOfMemory / JMeter / Profiler questions
Hello Tomcat'oids! We've started performance testing one of our REMOTE web apps using JMeter. We're gathering benchmark data before doing further fine tuning. Details: Win2K only have ssh + cygwin access to this remote server JDK 1.4.1_03 Tomcat 4.1.26, running as a service: a.. Use security manager 1 b.. Security policy file D:\Tomcat4\conf\catalina.policy c.. Initial heap 256 d.. Max heap 512 e.. Stack size 256 f.. JVM server Issue: We are getting OutOfMemory errors with very few threads simulated (as low as 5). More problematic, we've seen the OOM just after a Tomcat service restart! From the stack trace below, you can see we get the OOM before any of our code is executed :( Questions: a.. Anyone has seen this behavior upon Tomcat start up? b.. Anything particular to watch for in our JMeter test plan? c.. Would a profiler help? Could it profile a remote Tomcat installation? Any +/- feedback on Eclipse Profiler plug in (http://eclipsecolorer.sourceforge.net/index_profiler.html)? We'll work on gathering more data (e.g. periodic free / allocated memory dumps). Untill then, thank you for sharing your experiences, suggestions, code,...!

Re: Tomcat and JRockit
I've run Tomcat 5.0.x and 5.5.x on the 1.5 version of JRockit however it is worth noting that it breaks anything using CGLIB e.g. Hibernate so use with care. Apart from that though, I have found it to run very nicely.

JVM server I cannot help you with respect to your OOM problems, but I would recommend that you consider upgrading to JVM 1.4.2. You should also be able to migrate your app to TC 5.0.28 without too much grief. You should probably avoid TC 5.5.x for the meantime. JVM 1.4.2 and TC 5.0.28 play well together. Good luck in case!

Equivalent of Resin run-at servlet configuration
Hello, I am developing a Java web application, and one of the requirements is to run a particular servlet periodically, or even at specified times. Resin provides this ability via its run-at configuration element for servlets in web.xml Example Resin configuration: servlet servlet-namedownload/servlet-name servlet-classDownloadNewsServlet/servlet-class run-at period='360m'/ /servlet However, I haven't found an equivalent configuration for Tomcat. I searched the web and was unsuccessful. So, any pointers as to how I could achieve this for Tomcat would be appreciated.

AFAIK Tomcat dont provide a replacement for this. It is not in Servlet spec.

RE: OutOfMemory / JMeter / Profiler questions
You probably have either very large or very many sessions which Tomcat is attempting to reload on startup. Tomcat serialises sessions into files called SESSIONS.ser (in the application directories under the work dir) and then when it is restarted it attempts to reload them all. I presume this behaviour can be turned off. In terms of testing your app, you want to figure out whether you have a memory leak issue with your app, or simply that your max heap size is set too low for the load you are running. To check for memory leaks, you could run jmeter reasonably (although not too hard) excercising as much of your app as you can, repetitively and for an extended period. If it eventually keels over then you may need to investigate memory leaks with a profiler. Another possibility is that you may not be invalidating sessions and they are just being left to expire naturally. This can use up a lot of memory if you aren't careful and I supect is a quite likely source of your problems.

From the stack trace below, you can see we get the OOM before any of our code is executed :( Questions: a.. Anyone has seen this behavior upon Tomcat start up? b.. Anything particular to watch for in our JMeter test plan? c.. Would a profiler help? Could it profile a remote Tomcat installation? Any +/- feedback on Eclipse Profiler plug in (http://eclipsecolorer.sourceforge.net/index_profiler.html)? We'll work on gathering more data (e.g. periodic free / allocated memory dumps).

Re: Equivalent of Resin run-at servlet configuration
: I am developing a Java web application, and one of the requirements is to run : a particular servlet periodically, or even at specified times. Resin provides : this ability via its run-at configuration element for servlets in web.xml Tomcat doesn't have this. Are you trying to run that particular servlet, or just the business logic called by that servlet? Look into a scheduler (such as Quartz) to call that business logic for you at given times. You could also use Java's builtin TimerTask class, but (IIRC) that takes a Runnable or a Thread, so it's up to you to make sure those threads are properly terminated at container shutdown. Tomcat won't do that for you. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: RequestDispatcher.forward: SOLVED
Thanks to Tim and Remy for the answers;
For more explanations for those who have the same problem like me :
- see bugs 23211 and 33831 on http://issues.apache.org/bugzilla/
- In my example,
after ctx = ctx.getContext(/myNewContext);
but before dispatcher = ctx.getRequestDispatcher(/myNewServlet);
I can verify if my context (ctx) is the good one (or the context root) thanks
to :
ctx.getServletContextName() //if servlet API is 2.4
or ctx.getInitParameterNames() return a initParameter present in my
desired Context
or ctx.getAttributeNames() return an attribute present in my desired
Context
or ctx.getRealPath(/myNewServlet) is a Path valid for my desired Context

1) In other servlets containers, I read that
ctx.getRequestDispatcher(...) returns null if the resource is absent.
So, Why Tomcat reacts differently ? Is it a bug ?
2) In my case, I'd want to forward to myNewServlet if it is present, BUT,
if it is absent, I'd want to call another url distant (with httpclient)...
How can I do this with Tomcat ?

Re: How to approximate tomcat-5.0/4.x/3.x logging in 5.5?
Understandable. I was a little dismayed to see that what had been more automatic in Tomcat-5.0.xx had become less so in Tomcat-5.5. What I mean is, in Tomcat-5.0.xx, one could add a Logger to the context configuration file, deploy that with the webapp, and dynamically get a log file for ServletContext.log() output. In Tomcat-5.5, one has to have this in the logger config file at Tomcat startup, therefore forcing one to predict the apps that will be deployed to the appserver during runtime ... I was trying to achieve this with multiple separate log4j.properties, one in the container (common/classes/) for the uncaught stack trace and other general logging, and others in each webapp. With my setup below I was expecting to get THREE files: catalina.out (with stdout/err), tomcat.log (with the container's log4j output), and bar.log (with the webapp's log4j output, which I changed from ServletContext.log() to use Logger.info()). Instead, I got only catalina.out and tomcat.log, the latter containing everything that I thought the webapp would be sending to bar.log. And this should have worked. It works in every case I have ever tried. I suggest you double and triple check that you have log4j.jar in both common/lib and WEB-INF/lib and make sure you have log4j.properties in both common/classes and WEB-INF/classes. OK, thanks to your vote of confidence in the method, I dug further and discovered that my WEB-INF/classes/log4j.properties was never being found.

Re: Equivalent of Resin run-at servlet configuration
Well, I use a servlet that is kicked off at container start(On TC 3.x used load-on-startup attribute, TC 5.x+ there is something else which is now part of the J2EE spec). Most other containers have a load-on-startup type attribute available to them. When that servlet is init()ed at container start I kick off a class which loads more class names out of the web.xml that are Runnable. This parent class then kicks off a thread for each Runnable, and handles making sure they are all reaped when the destroy() method of the servlet is called(usually at container shutdown). There are better ways of doing this now with the newer TC's. If you don't shutdown your child threads, there may be a possibility that they will remain running after TC stops. Good luck. -JW Lionel Farbos wrote: I think that what you want, with this feature, is a daemon (but not a servlet that respond to requests).

System load creeping up with Tomcat + Lucene
Hi, I'm using Tomcat and Lucene to build a search engine. I suspect this is a Tomcat problem, but I can't be sure. The system load and CPU usage by Tomcat keeps creeping up with http-8081-Processorn threads becoming stuck in _hpiThreadHardSuspend in libhpi.so. For example, I might get 10 or more threads similar to what I pasted below. Any ideas?

Once you have that set, it will probably work as expected.

Contexts
I inherited an application recently that uses Tomcat 5.0.16. I know that previous to Tomcat 5, Context elements were in Tomcat's server.xml, but with Tomcat 5 it is recommended that Context elements be in their own .xml files under /conf/Catalina/host/. In this application, however, there are Context elements in BOTH places - when this is the case, does one overwrite the other, do they cancel one another out, what?

For TC 5.x.x, you need two security-constraints to do what you want.

path attributes in context xml files
I use xml files in /conf/[enginename]/[hostname] to define my contexts. I now know that Tomcat 5.5.x doesn't allow for 'path' attributes in the Context elements when defined that way. Previously, I could specify the path as '/dir1/dir2/appname'. I can easily rename the xml file to 'appname.xml', but how do I get the other directories into the path without a 'path' attribute in the Context element. Using the 5.5.x approach, by web application is at '/appname' instead of '/dir1/dir2/appname'. Is there a way to get a multi-directory path using this approach (a la Tomcat 5.0.x), or will I need to declare these Contexts in my server.xml to do that?

No, meaning impossible? cause if it would be very beneficial to many then why not change the specs to accommodate such service? Pardon me, maybe because I really don't understand the specs.

Re: Equivalent of Resin run-at servlet configuration
run-at is an extension to web.xml that is not portable across containers. That's why it will not be implemented. -Tim Aris Javier wrote: No, meaning impossible? cause if it would be very beneficial to many then why not change the specs to accommodate such service?

Re: Equivalent of Resin run-at servlet configuration
And so the best way is to have a set of classes to add to your project that add this feature. It then moves with the app and can be applied per app or even as a jar in common lib for use by all apps. Tim, am I thinking right on this? Remember that Tomcat follows the spec which is developed and created by others. So impossible is not an accurate statement. Anything is possible. But this is not the forum to lobby. Tomcat nor Apache are the creators of the spec. They only follow it. Now if you want to lobby these folks, fell free to. You never know, it may be something that is being considered and another voice may help. As for Tomcat if you start adding things that are not spec driven you open yourself up for controversy and problems down the road. Just trying to follow the spec can be a pain in itself, for each creator of a container will interpret some areas differently. Knowing that you app will run on any container because the container you run on follows the spec can be a big load off a developers mind. Although I am not one of the developers working on Tomcat, I think this is why you are seeing some of the changes that have occurred in the last year. Tomcat is moving away from non spec features and trying to tow a tighter line. NOTE: This is my opinion as an outside observer. I know the developers sound a little rude or abrupt, but remember that is many way their hands are tied. They are committed to building a reliable product that is widely accepted and compatible/comparable to other containers. To accomplish this they must do their best to follow the spec for failure to do so would result in just that, failure. I am sure there are tons of features and ideas that they would love to add, but can't because of the spec. I have spoke up, many times, in defense of the wonderful folks who spend so much of their time on Tomcat. I do this because it is one way that I can contribute back. I do this not to belittle you or anyone else, but to inform you and help you and others understand. These guys do a great job and I for one am very thankful. So if someone will write these classes, and someone will host them maybe we can get a link off the Tomcat in the FAQ section??? Just a thought.

I'm attempting to get the JNDI Datasource How To
example for Postgresql to work.
Here is the URL for the example:

page reports:

Here are all my configuration steps, including the
files:
- On Fedora Core 3 - adduser postgres
- passwd postgres (set to postgres)
- chown postgres /var/lib/pqsql/data
- /usr/bin/initdb -D /var/lib/pgsql/data
- /usr/bin/postmaster -D /var/lib/pgsql/data logfile

- createdb test postgres
- psql test
create table testdata (id int not null primary key,
foo varchar(25), bar int);
insert into testdata values(1, 'hello', 12345);
- Update server.xml with this under the /Host tag:

Tomcat 5.5.4: Define a default application w/ Context Descriptors?
Hi All, I would like to know how to define a default application w/ Context Descriptors. On Tomcat 5.0, I could define a default application w/ a context descriptor fragment in: $CATALINA_HOME/conf/[enginename]/[hostname]/foo.xml The file foo.xml would contain this entry: Context path= docBase=c:/test/website/ However, in Tomcat 5.5.4 the context name is tied to the context descriptor filename. The path attribute is ignored. Right now, the only solution I see is to place it in the server.xmlbut that is not recommended by the Tomcat 5.5 docs. Thanks in advance for your help. // Darby - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
