Re: How to configure different default webapp in function of requested hostname on one tomcat server
Hello, even if you decided to remove httpd and go directly with virtual hosts in tomcat, there are two things in your httpd config, which could be advanced (see inline below).

Until now, I have created a virtual host in Apache with this configuration : JkMount /* default I think you want /|* which matches / as well as /ANYTHING_ELSE.

Since this isn't happening in Tomcat, I am unable to retrieve the query string client side. As you indicated my login page is static html and I am relying on client-side processing to interpret the query string. I ended up working around the issue by creating a loginerror.html which is identical to login.html except that I have added a hidden DIV to the loginerror.html. I can then search for the hidden DIV to determine if there was a login failure or not. Not pretty, but it works! If you're using client-side scripting, why not just set a class or id on the body for each type, instead of the hidden div? p Thanks Shaun On Wed, Aug 25, 2010 at 10:17 PM, Christopher Schultz ch...@christopherschultz.net wrote: Shaun, On 8/23/2010 4:56 AM, Shaun Senecal wrote: I'm using FORM authentication, and everything seems to be working (logins are accepted, etc), except when there was an error the URL changes in the users browser to point to j_security_check.

How are you checking? If you are forwarding to a .html page, you probably don't have any dynamic content in there, and therefore have no options for checking for things like request parameters. Is there something obvious I am doing wrong here? I got it working under Jetty as a sanity test, but I need to get it working in Tomcat too... It's possible that Jetty performs a redirect (to login.html?error=true) during a failed login and Tomcat performs a forward, which is entirely server-side. The result is that the client never sees the error=true and therefore only server-side components will be able to see it. -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org 0x62590808.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature

Hi. It is very likely that by changing the default parameters of Apache, mod_jk and Tomcat without first knowing exactly where the slowness is happening, you are making the situation worse rather than better. It is also very likely that the webapp itself is the limiting factor. Apache + mod_jk + Tomcat, in their default configuration, by themselves, can handle several hundred requests per second. If you do not believe this, then try it yourself : set up a static html page inside tomcat's ROOT webapp, make sure that the mod_jk configuration forwards these requests to Tomcat, and then use ab to make requests to that static page, just to convince yourself. Then use one of the Tomcat standard example webapps, and do the same. Then, use Tomcat's AccessLogValve (http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access_Log_Valve) to compare the processing times between static pages, an example webapp and your webapp. When you really understand where the problem seems to happen, then come back and ask more precise questions. The point is : the default configuration of Apache, mod_jk and Tomcat is *already* tuned to perform well in most standard situations. If there existed any way in general to tune these things better, and the Apache, mod_jk and Tomcat developers knew it, then of course *that* would become the default configuration. The point is also : nobody here has any idea of what your old webapp is doing; only you know that. If it is making 10,000 disk accesses each time it processes a request, then maybe what you need is a faster disk. If it builds a huge table in memory each time it is called, then maybe you need more memory. Etc.. One last thing : Tomcat 4.1 and the JVM 1.4.2, both, are about 10 years old, and not supported anymore. The current versions are free, and supported. Do yourself (and everyone else) a favor and make your testing on the latest versions. Your webapp should work just as well (or better) with them. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: another UTF-8 problem
Thanks for your responses. The problem was not the response from the web service. Something must have been completely mixed up. I set the Java option -Dfile.encoding to utf-8 which solved the write to file problem and also put this in the code: if (req.getCharacterEncoding() == null) req.setCharacterEncoding(UTF-8); res.setContentType(text/html; charset=UTF-8); res.setCharacterEncoding(UTF-8); Which solved the encoding of the response I got from the servlet.

If you're connecting-out to a SOAP service, then the URIEncoding setting doesn't matter. I'm connecting to a web service which returns UTF-8 encoded data. If I do so from a plain, regular, self-contained Java application everything is fine. However, if I run the same classes in tomcat (and trigger the action with a http request instead of a main() method in the application) I get latin-1 encoded characters. For instance when I make a call and receive a response which contains Łódź I finally get ?ód? (console, file, whatever output). Are you sure it isn't the encoding to your console/file/whatever that isn't set properly? If you are getting a response that contains non-ASCII characters, they ought to be encoded using the declared XML document's encoding. What is that? Are the bytes correct in the response (before your SOAP client parses them)? Does your SOAP client parse them correctly? You may have to use a profiler to verify that the characters in memory are what you expect them to be. Actually the URIEncoding option should not have anything to do with this, because I'm not sending a request to my application, but my application is issuing a SOAP call to a web service. Are there any other options to consider? Same response from the web service (checked with Wireshark) but different outputs. I've no idea. Any hint is welcome. So, when you use your own command-line app as a client, you get a different response from the SOAP server than when you use Tomcat as the client? You should look at the requests that are being sent. Perhaps there is a bad accept-charset header or something (although that probably shouldn't affect the XML response, since an XML parser is pretty much required to support UTF-8). - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxz7SoACgkQ9CaO5/Lv0PCNOQCeLLBz/6e3QNsPyQtw4Ggfnh7R sYsAn3PNB9UqJDunLDeMyQrz6a3Edbao =/0N2 -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Access StandardContext in WebappClassLoader
Hi guys, I'm using tomcat 6.0.18 adapted to osgi environment and I would like to make the WebappClassLoader configurable so that it does not load certain packages directly through the system class loader but use the class loader hierarchy instead. In order to do that I have extended the standard webapp class loader and configured the container to use the new one in the base context.xml. I want to configure the packages through a context parameter (separately for each webapp) or eventually through an env-entry. However I cannot find a way to access the StandardContext instance in my WebappClassLoader. This is probably a very simple thing to do but I'm not really well familiar with catalina API and this is kinda driving me crazy. Any help/suggestion is more than welcome. Thanks in advance Stefan

Example : To put DNS aside for a moment, suppose I have this in my local hosts file (which is consulted by the local resolver before DNS gets involved) : 212.85.38.176 mira mira.wissensbank.com (and, at this IP address, is a host with a Tomcat server listening on port 80) So, as far as my local workstation is concerned, both mira and mira.wissensbank.com are aliases of eachother, in the sense that they both resolve to the same IP address. A) Then, I start a browser and request : http://mira/ - the browser calls the local resolver to resolve mira into an IP address - the local resolver looks up mira in the local hosts file, finds it, and returns the IP address 212.85.38.176 - the browser now establishes a TCP connection with IP address 212.85.38.176 - when the TCP connection is obtained, the browser sends the following request over that TCP connection : GET / HTTP/1.1 Host: mira ... - the Tomcat at this IP address gets the Host: header's value (mira), and looks up to find a Host in its configuration, which has either - the Host attribute name=mira - or an Aliasmira/Alias If it does not find such, the request is passed to the default Host B) If instead, the request which I type in the browser's URL bar is http://mira.wissensbank.com then - the browser calls the local resolver to resolve mira.wissensbank.com into an IP address - the local resolver looks up mira.wissensbank.com in the local hosts file, finds it, and returns the IP address 212.85.38.176 - the browser now establishes a TCP connection with IP address 212.85.38.176 - when the TCP connection is obtained, the browser sends the following request over that TCP connection : GET / HTTP/1.1 Host: mira.wissensbank.com ... - the Tomcat at this IP address gets the Host: header's value (mira.wissensbank.com), and looks up to find a Host in its configuration, which has either - the Host attribute name=mira.wissensbank.com - or an Aliasmira.wissensbank.com/Alias and if it does not find such, the request will be passed to the defaultHost. All the above remains true even if there is nothing in the local hosts file, and the above translations to IP address are made via a DNS lookup. So, let's say that this Tomcat only has the following (non-default) Host tag : Host name=mira.wissensbank.com /Host then any request addressed by my browser to http://mira will end up being served by the defaultHost. As long as the browser /can/ resolve the hostname into an IP address, it will always make the connection to that IP address and send the request over it. But the content of the Host: header will be the hostname as indicated in the request URL, as is, and not necessarily translated to its canonical form. Whether Tomcat itself would attempt to do some kind of DNS lookup for a partial name, in order to canonicise it, is besides the point really, because even if it would - which would surprise me - there is no certainty that it would be able to translate mira into mira.wissensbank.com. It is very frequent in intranets to have a mixture of links floating around, some referring only to the hostname, some with the full FQDN. If you want Tomcat to respond properly to both kinds of links, you must have both names referenced inside the Host section, whether as the host name, or as an Alias. It does not matter which one of them you use for the Host attribute or the Alias, but they must both be there, or some requests will end up with the defaultHost. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Upload them separately to each server, check integrity and then run a local script to finish the process and deploy them to appBase do server restarts if needed. If you're deploying to production servers with auto-deployment enabled, make sure the upload occurs to a separate temp location, before copying it into the appBase. You could SCP files up to a location on the server, using a user account configured with a password-free key pair.

That's because these two classes have no relationship to one another.

Any help/suggestion is more than welcome.
The WebappClassLoader is just a ClassLoader that loads down instead of
up like traditional ClassLoaders. It's not really webapp or
context-specific in it's code... it's just that the servlet spec says
that webapps need to load classes locally before looking up the
ClassLoader tree, so this class was written to do just that.
The WebappClassLoader isn't tied to the webapp/context other than it's
the one that's been assigned to the context as it's ClassLoader.
Instead of trying to reach-down from the ClassLoader to the
StandardContext, why not do the reverse: register a
ServletContextListener that configures the (already-created)
ClassLoader. Something like this:
public class CrazyClassLoaderConfigrationListener
implements ServletContextListener
{
public void contextInitialized(ServletContextEvent e)
{
ClassLoader cl = this.getClass().getClassLoader();
if(!(cl instanceof CrazyClassLoader))
cl = Thread.currentThread().getContextClassLoader();
if(cl instanceof CrazyClassLoader)
{
((CrazyClassLoader)cl)
.configure(e.getServletContext()
.getInitParameter(packages));
}
else
{
e.getServletContext().log(Could not configure CrazyClassLoader);
}
}
}
That's a little late to be setting the ClassLoader configuration, but it
will happen before your servlets are loaded.
Of course, you could also just use a .properties file to configure your
ClassLoader.
The real question is: what is it that you're really trying to do?

Re: Access StandardContext in WebappClassLoader
Hi again
and thanks for the quick responses.
What bothers me in the WebappClassLoader is the fact that before it checks
its repositories (lib folder and classes) and asks its parent class loader,
it will first attempt to load a class from the system class loader - from

want it to be configurable for each web application. That's why I wrote my
WebappClassLoader and configured its usage in the default context.xml
(Loader loaderClass=org.chefo.OSGiWebappClassLoader/ in catalina
home/conf/context/xml). I figured the easiest way to configure a list of
packages that should not be loaded through the system class loader is with a
parameter in the context of the web application, thus I need to access a
context parameter in my webapp class loader. I thought it would be normal
for the webapp class loader to be able to access the context that is
associated with it...
Hope that makes it a bit clearer...

I'm using tomcat 6.0.18 adapted to osgi environment and I would like to

What ClassLoader hierarchy?
In order to do that I have extended the standard webapp class
loader and configured the container to use the new one in the base
context.xml.
Ok.
I want to configure the packages through a context parameter
(separately for each webapp) or eventually through an env-entry. However
I
cannot find a way to access the StandardContext instance in my
WebappClassLoader.
That's because these two classes have no relationship to one another.
This is probably a very simple thing to do but I'm not
really well familiar with catalina API and this is kinda driving me
crazy.
Any help/suggestion is more than welcome.
The WebappClassLoader is just a ClassLoader that loads down instead of
up like traditional ClassLoaders. It's not really webapp or
context-specific in it's code... it's just that the servlet spec says
that webapps need to load classes locally before looking up the
ClassLoader tree, so this class was written to do just that.
The WebappClassLoader isn't tied to the webapp/context other than it's
the one that's been assigned to the context as it's ClassLoader.
Instead of trying to reach-down from the ClassLoader to the
StandardContext, why not do the reverse: register a
ServletContextListener that configures the (already-created)
ClassLoader. Something like this:
public class CrazyClassLoaderConfigrationListener
implements ServletContextListener
{
public void contextInitialized(ServletContextEvent e)
{
ClassLoader cl = this.getClass().getClassLoader();
if(!(cl instanceof CrazyClassLoader))
cl = Thread.currentThread().getContextClassLoader();
if(cl instanceof CrazyClassLoader)
{
((CrazyClassLoader)cl)
.configure(e.getServletContext()
.getInitParameter(packages));
}
else
{
e.getServletContext().log(Could not configure CrazyClassLoader);
}
}
}
That's a little late to be setting the ClassLoader configuration, but it
will happen before your servlets are loaded.
Of course, you could also just use a .properties file to configure your
ClassLoader.
The real question is: what is it that you're really trying to do?

Re: Best practices for deployment on cluster environment
I haven't tried this in production (yet) so your mileage may vary.
In the cluster setup, there's a FarmDeployer element that can be used to deploy
across the cluster.
The host that does the deploying:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=true/
And the hosts that get the web application:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=false/
For large web applications and frequent deployments, this might generate a lot
of network traffic.
Also, it's not intuitive (to me) how processDeployFrequency works, but I need
to
look at the code. In any case, you might have the Tomcat doing the deploying
not
actually serving content.
I found out that you can use ${variable.name} in configuration files, so it's
now much easier to clone installations and just edit setenv.sh(bat) as
appropriate.
Hope this helps.
. . . just my two cents.

Could you share your experience with this kind of environment? Is this the
best
way to deal with deployment?
Scripting your deployment process is a Good Idea. It will also mean
that it happens the same every time, according to whatever your scripted
procedure is.
Upload them separately to each server, check integrity and then run a
local script to finish the process and deploy them to appBase do
server restarts if needed.
If you're deploying to production servers with auto-deployment enabled,
make sure the upload occurs to a separate temp location, before copying
it into the appBase.
You could SCP files up to a location on the server, using a user account
configured with a password-free key pair.
SSH will let you limit a given key to specific commands, so the account
could be configured solely for uploading the files then running the
local deployment script.

Re: Best practices for deployment on cluster environment

I haven't tried this in production (yet) so your mileage may vary.
In the cluster setup, there's a FarmDeployer element that can be used to

FarmWarDeployer would certainly benefit from more production usage. I'm
not sure the reverse is true.
p
The host that does the deploying:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=true/
And the hosts that get the web application:
Deployer className=org.apache.catalina.ha.deploy.FarmWarDeployer
tempDir=${catalina.base}/temp-dir/
deployDir=${catalina.base}/webapps/
watchDir=${catalina.base}/watch-dir/
processDeployFrequency=4
watchEnabled=false/
For large web applications and frequent deployments, this might generate a
lot
of network traffic.
Also, it's not intuitive (to me) how processDeployFrequency works, but I need
to
look at the code. In any case, you might have the Tomcat doing the deploying
not
actually serving content.
I found out that you can use ${variable.name} in configuration files, so it's
now much easier to clone installations and just edit setenv.sh(bat) as
appropriate.
Hope this helps.
. . . just my two cents.

Hi,
I have a Tomcat cluster environment with 4 servers. I was wondering that is
the
best way to deploy an application on 4 servers at the same time.
At a first moment, i thought about having a script that would copy war files
to
all servers using rsync. Basically i upload the war file to the first server
and
them use this script to copy to other tomcat servers.
Could you share your experience with this kind of environment? Is this the
best
way to deal with deployment?
Scripting your deployment process is a Good Idea. It will also mean
that it happens the same every time, according to whatever your scripted
procedure is.
Upload them separately to each server, check integrity and then run a
local script to finish the process and deploy them to appBase do
server restarts if needed.
If you're deploying to production servers with auto-deployment enabled,
make sure the upload occurs to a separate temp location, before copying
it into the appBase.
You could SCP files up to a location on the server, using a user account
configured with a password-free key pair.
SSH will let you limit a given key to specific commands, so the account
could be configured solely for uploading the files then running the
local deployment script.

Yes, there is a web interface for it, but is (evidently) sends everything to the central Unicorn service for actual validation. Try reading the source: there's not much of it. In fact, start with the servlets themselves (there are only one or two). You ought to be able to figure out how to duplicate the Unicorn client calls in a non-servlet environment.

Re: pick load
Thanks. I got the dump of the running JVM (only the benchmark is running at dump time). I tried to take a look at it, but as am not familiar with java, I prefer talk about it here. -first I noticed the number of TP-Processor is twice the number of concurrent resquests send by ab (why twice? i don't know). About half of them are in Object.wait state TP-Processor40 daemon prio=1 tid=0xdef53168 nid=0x646f in Object.wait() [0xda729000..0xda7291b8] at java.lang.Object.wait(Native Method) - waiting on 0xe17bc808 (a org.apache.tomcat.util.threads.ThreadPool$ControlRunnable) at java.lang.Object.wait(Object.java:429) at org.apache.tomcat.util.threads.ThreadPool $ControlRunnable.run(ThreadPool.java:661) - locked 0xe17bc808 (a org.apache.tomcat.util.threads.ThreadPool$ControlRunnable) at java.lang.Thread.run(Thread.java:534) and the other half is waiting for a monitor entry.

Re: failed FORM authentication redirects to /j_security_check
Currently the only content in the HTML file is a script tag, since I am using GWT for the UI. I dont think there is any way I can set a class/id on a script tag, so I went with the empty DIV and put a known id on it. You're right though, I could have reused an existing element for this purpose as well.

Jetty does a redirect, so on the client-side the browser sees /login.html?error=true. Since this isn't happening in Tomcat, I am unable to retrieve the query string client side. As you indicated my login page is static html and I am relying on client-side processing to interpret the query string. I ended up working around the issue by creating a loginerror.html which is identical to login.html except that I have added a hidden DIV to the loginerror.html. I can then search for the hidden DIV to determine if there was a login failure or not. Not pretty, but it works! If you're using client-side scripting, why not just set a class or id on the body for each type, instead of the hidden div? p Thanks Shaun On Wed, Aug 25, 2010 at 10:17 PM, Christopher Schultz ch...@christopherschultz.net wrote: Shaun, On 8/23/2010 4:56 AM, Shaun Senecal wrote: I'm using FORM authentication, and everything seems to be working (logins are accepted, etc), except when there was an error the URL changes in the users browser to point to j_security_check. This is expected. The contents of the redirect to j_security_check contains login.html, so the user is able to login as expected, but my error=true query string is not passed along. How are you checking? If you are forwarding to a .html page, you probably don't have any dynamic content in there, and therefore have no options for checking for things like request parameters. Is there something obvious I am doing wrong here? I got it working under Jetty as a sanity test, but I need to get it working in Tomcat too... It's possible that Jetty performs a redirect (to login.html?error=true) during a failed login and Tomcat performs a forward, which is entirely server-side. The result is that the client never sees the error=true and therefore only server-side components will be able to see it. -chris - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
