Re: tomcat 7 in debian/ubuntu
Hi Rodrigo. As far as I am aware, there is currently no Tomcat 7 debian package tree being worked on, nor am I currently working on one. I have recently been discussing the possibility of working on a Tomcat 7 package that goes across both deb and RPM formats (in an attempt to merge lots of duplicate efforts, and to promote more Tomcat compatibility across Linux distributions), but as of now that's just an idea I bounced off of a couple of people. I do agree that Tomcat 7 packages are needed now.

Re: Tomcat Consultant
Hi Chris. I'm surprised you hadn't heard of it yet. Disclaimer: I work for MuleSoft. Just so you know (in case our web pages don't clearly state this), Tcat is about trying to make it easier to use open source Tomcat in production enterprise environments. It's not, in any way, trying to replace open source Tomcat, nor is it a Java EE app server. By making it easier to monitor and manage the open source Tomcat instances people already run in production via our Tcat Server console, we're helping Tomcat to be easier to use, more stable, and to perform better in production due to increased stability and visibility. In case you want to try it, it's free (as in beer) to download. You get the full version. If you like it enough to deploy and use it in your production environment, that's when it begins to cost, but it's free for use in your development environment, test environment, and staging. It hooks up to any Tomcat 5.5.x, 6.0.x, and 7.0.x beta. We'd like to know what you think of it once you've tried it. MuleSoft also offers training and consulting on Tomcat, though we're mainly focused on Tcat and the Mule open source ESB.

Re: httpd vs. Tomcat performance
Very entertaining reading! Thanks Chris and Mark for re-benchmarking, explaining, and giving your opinions on the results. I'm not entirely sure how I missed Chris' benchmark results email, almost exactly one year ago now. Chris: there are no units on your results numbers, and I'm not seeing any procedure you used, nor any configurations you used, so I'm not sure how to interpret the numbers. It would be great to get more information about how the benchmark was conducted, which HTTP client was used, and what server hardware was used. I tried to write my benchmark such that it is fully documented and repeatable all the way down to the configuration used on both the client and the server, etc. I also wanted to be completely clear and up front about the specific scenarios I was benchmarking -- there are many more that I wasn't -- so I wrote the explanations into the text as well. The results are, of course, only about the kinds of requests we're benchmarking, and also about the configuration(s) used. I did try to think up and benchmark the most likely use cases for serving typical webapp content, but anyone can say their webapp isn't like that. :) Plus, I tried to write my benchmark to both inspire others to conduct and publish more benchmarks, and also to show a detailed example of one that others could modify and re-use. I was hoping to see more published benchmarks by now, but each one I find is really entertaining. I'm happy to see that Chris' independent benchmark numbers help to show that it is indeed a myth that Tomcat needs HTTPD in front of it in order to get good performance serving static files. And, it's great to see benchmark results for file sizes that I wasn't able to benchmark. Mark: I like your text about some of the other reasons people want to use HTTPD -- it is spot on, and in fact there are so many modules out there for it, there are countless logical reasons to use it.

Re: Centralize settings...
Yes, using Tcat Server profiles is another way. Create a new profile that contains all of the Tomcat configuration you want, and any files you want to add into your Tomcat installation (binary or text), and you can apply the profile to any number of regular Tomcat installations, potentially across multiple machines. The console allows you a central point of administration of the server profile. See this page for some more details: http://blogs.mulesoft.org/saving-time-using-tcat-servers-centralized-configuration-management Tcat Server is commercial software, but it is free for pre-production use. There are other ways of centrally administering a set of configuration files for doing what you're asking about, though I think they're more time consuming, or they involve some custom programming, or both. Some examples include: 1. Writing your own Ant build files that use the SSH task to scp files to the machines that should have the files. This works fine, but involves lots of custom programming. 2. Writing a shell script that uses rsync or SSH, which ends up very similar to #1. 3. Using a more complex configuration management tool such as SystemImager http://systemimager.org but it isn't as simple to get it working, it makes some assumptions about what you're trying to do that probably aren't correct, and it doesn't provide any Tomcat specific features, such as server diagnostics, webapp deployment, or server restarts. SystemImager is only for imaging whole machines.

You're right that you would need to modify Tomcat's code to do that. Commons-digester would need to be told how to read a new nested element.

Re: AccessLogValve calling order
Hi Chris.
Thanks for diagnosing this problem! It appears you're right that it logs
only after the session is invalidated (after the request is complete) on a
logout request. That bug has existed in the code for a very long time,
unnoticed. The AccessLogValve was initially implemented to log only after
the request processing is complete so that the client never needs to wait
for the logging to complete. With the new addition of asynchronous logging,
however, it's quite a bit less important to log only when the request is
complete. It seems like it would help if the access logger could be
configurable to log either before or after handling the request (I'm not
sure logging both before and after makes sense). Your ideas for %Sr and
%{methodName}rm both seem useful as well, though I think the %{methodName}rm
one has potential security side effect issues. So, I would suggest
implementing your first two ideas. I'm also happy to help you with that, if
you'd like.
Cheers.

All,
Amazingly enough, I had my first need to use AccessLogValve today, and
one of the things I wanted to print was the user's session id. No,
problem: just add %S to the log pattern.
Well, there is one problem: you can't spit-out the session id for logout
requests because the logic for the AccessLogValve is:
if(enabled)
invoke next valve
print log message
else
invoke next valve
Note that the request has essentially completed when the log message is
generated. This makes complete sense as you typically want to log
/after/ the request so you can do things like find out how many bytes
were sent, how long the request took, etc.
In my case, I want to have access to the session id before the session
is invalidated (which happens in the logout servlet).
Another option would be to get the requested session id from the request
(which can only be done with the current AccessLogValve if the client is
using cookies), though that can be misleading because anyone can request
anything... it's not guaranteed to use a useful value.
Anyhow, I was wondering if anyone had any suggestions short of heavily
modifying the AccessLogValve or developing something from scratch.
I'd also be happy to provide a patch for the AccessLogValve that add any
or all of the following capabilities:
1. Allow log before or after request (or both?)
2. Add requested session id to standard pattern options (%Sr?)
or
3. Add %{xxx}rm to call ServletRequest.xxx and print the result
(allows ${getRequestedSessionId}rm

Re: multiple truststores
Hi Aron. You do not need two separate Tomcat instances for this. In your server.xml file, you'll notice that your HTTPS Connector elements are nested within a Service element. Also nested within the Service element is an Engine element that in turn contains your Host(s) and Context(s), like this (simplified): Server Service Connector port=443/ Connector port=444/ Engine Host name=yourhostname Context path=/webapp1/ Context path=/webapp2/ /Host /Engine /Service /Server Tomcat matches up the Connectors with the Engine and the Engine's Hosts and Contexts. Tomcat also supports having more than one Service element in server.xml, which means you can change the structure so that only one connector is able send requests to one webapp, like this: Server Service name=Catalina Connector port=443/ Engine Host name=yourhostname Context path=/webapp1/ /Host /Engine /Service Service name=Catalina444 Connector port=444/ Engine Host name=yourhostname Context path=/webapp2/ /Host /Engine /Service /Server -- Jason Brittain MuleSoft http://www.mulesoft.com On Fri, Oct 16, 2009 at 8:02 AM, tom...@ehome.hu wrote: Hi all, I am trying to get to work two web applications with client-side SSL Authentication.

Re: Accessing a database from a Valve
Sometimes, maybe infrequently, there's a decent reason to implement a small amount of code outside of the webapp, in the container space. There are cases where either modifying the webapp is off limits, or where it would simplify things to implement it in container space so that it's just always running, regardless of which webapps are started, stopped, deployed, undeployed, or redeployed.

Re: How to check if the client dropped the connection
Hi Andrea. When the client disconnects, and your servlet tries to write to the output stream, Tomcat will throw a ClientAbortException (you may have already seen this): http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/connector/ClientAbortException.html Tomcat appears to only throw this exception when you either write some bytes to the output stream or when you flush the output stream, and the client already closed its end of the connection. It appears that you could periodically try flushing the output stream and see if doing so throws this exception. You can flush after writing any number of bytes, including zero bytes. The first time you call flush, it will send the HTTP response headers to the client, so you would need to first set the headers before flushing. That sounds difficult for you to do because you're writing an image, and one of the headers would be Content-Length, which you probably don't know until your image is generated. -- Jason Brittain On Mon, Sep 28, 2009 at 12:21 AM, aaime74 andrea.a...@gmail.com wrote: Hi, I'm working on the development of an open source application, GeoServer, implementing the Web Map Service specification.

By spec we're forced to use a plain request and response approach, but we're experiencing a problem with clients making lots of request as the user zooms/pans around: basically a request is made, but the user keeps on moving, the client drops the older requests (closing the connection in face of the server) and makes others. Unfortunately in the meantime the older requests are still running, drawing a map takes time and a lot of memory, for example the above request, which is a small one btw, allocates a BufferedImage of 700KB. The memory is consumed up until the image is encoded out to the stream, which is also the moment we finally figure out the client dropped the connection (since writing to the servlet output stream fails). This is very sub-optimal. Servers like Apache with cgi do kill the cgi process the moment the connection is dropped, significantly reducing the server load both in terms of CPU and memory consumption. Is there any way to check if the client connection is still open using only the standard servlet API? If not, is there any Tomcat specific approach that might work instead?

Re: access log and Apache server
Hi Angelo.
I'm assuming you're using mod_proxy_http (you said port 80). If so, then
there is indeed a way to make this work.
In your Apache HTTPD config, where you're configuring proxying the request,
make sure you add:
ProxyVia On
That will make HTTPD set the x-forwarded-for HTTP request header's value
to the IP address of the client. This is passed to Tomcat when HTTPD
proxies the request.
Then, where you're configuring the AccessLogValve (usually in your
conf/server.xml file), change the default logging pattern to log the
x-forwarded-for header value, like this:
Host ...
Valve className=org.apache.catalina.valves.AccessLogValve
directory=logs
prefix=localhost_access_log.
suffix=.txt
pattern=%{x-forwarded-for}i %l %u %t %r %s %b
resolveHosts=false/
/Host
With that configuration, AccessLogValve will log the x-forwarded-for header
value that is set by Apache HTTPD's mod_proxy, and the remainder of the
logging pattern will be the same as usual.
Cheers.

Re: Maximum Number of processes Exceeded
Hi Sharath. Can you tell us more about your environment? For example: - Your operating system brand and version. - Your Tomcat version, where you initially got it, how you installed it. - Your Java VM brand and version, and whether it is a JRE or JDK. - Your Oracle version. - Your Oracle JDBC driver version, where you got it, how you installed it. Please give us as much of the above information as you can. Thanks. -- Jason Brittain On Thu, Sep 17, 2009 at 7:22 PM, Sharath Babu S S S sharath.b...@solix.comwrote: Hi, We are using Tomcat Server and oracle database.
