i need to map a custom paths, like /path1 and /path2, (not root

http://path2.com/
NOT this: ${samewebapp}/path1 is mapped to http://path1.com/path1
${samewebapp}/path2 is mapped to http://path2.com/path2
What is ${samewebpp}/path1? Is that a piece of a webapp?
Do you care if the same webapp is deployed twice (which is probably
going to be required)?
Actually the OP is not really clear in describing anything. I'm
wondering if path1 in http://path1.com equals path1 in the
/path1 part or not.
actually the path names and domain names should be able to be different
Anyway I would say a context.xml file in conf/catalina/path1 (the
hostname)/path1.xml (the context name) should do the trick?
Place the webapp outside the appbase of the hosts and then point the
docbase to the webapp (or just drop the .war with two
different names in the appbases of the two hosts) :)
i want to have one instance of webapp,
which has two paths,
and each of the paths serves the root of different domains
once again:
* one webapp
* has 2 different paths: /path1 and /path2
* served on 2 domains
* when user goes to http://path1.com/ - {webapp}/path1 is served as
root path
* when user goes to http://path2.com/ - {webapp}/path2 is served as
root path
is it possible?
To me it doesn't make sense to say that the webapp has two different
paths, /path1 and path2, and then say the webapp is to be served as root
from two different hosts. I guess it's simply a case of bad terminology :)
Anyway. What you are trying to do is make the same webapp answer both
domain1.com/ and domain2.com/ right? If so you can simply deploy the
webapp as ROOT. The webapp will then answer on all domains pointing to
the server. If this is not what you want, you can set up a virtual host
in server.xml with an appbase outside the webapps folder (eg.
$CATALINA_BASE (or is it HOME?)$\domain1 and then use the Alias
element to specify the second domain as an alias for the first (which
you set as an attribute in the Host element).

Two different instances of the same webapp at different hosts - easy.

One instance mapped to different paths - impossible. What value should

When I try the following it returns null:

You should beware of the difference between Class.getResource() and
ClassLoader.getResource().
I realize I can do the following, but I don't want the code to be server

You can make the path configurable with an init-param in your context.

Re: Fw: Can not understand how maxThreads of Connectors works
I am using the correct server.xml.
In the version 5.5.36 the maxThreads of 0 has no effect due to this code in
org.apache.tomcat.util.net.PoolTcpEndpoint
public void setMaxThreads(int maxThreads) {
if( maxThreads 0)
tp.setMaxThreads(maxThreads);
}
So what I observe is correct. I.e. with 0 there is no error and also my web

That last one is not true: the code will happily accept maxThreads=0

start its Executor.
I suspect Hermes is editing some unrelated server.xml file: his
observations seem totally in-line with that hypothesis.
Hermes, try modifying your server.xml file to be syntactically
incorrect. For example, put a !-- into the middle of the file and
try to start Tomcat. If it still starts, you are editing the wrong file.

Re: Loading a DeSerialized Class to WebabbClassLoader Question
Hi again Chris, comments below On 01/24/2013 07:05 PM, Christopher Schultz wrote: What if you try this: ClassLoader contextClassLoader = Thread.currentThread().getContextClassLoader(); FileClassLoader cl = new FileClassLoader(contextClassLoader); Class? spClass = cl.arrayToClass(null, byArray, True); Thread.currentThread().setContextClassLoader(cl); Tomcat changes the context ClassLoader all the time, and you'll want your ClassLoaders to remember previously-loaded classes, so this isn't a great solution in general. That's why I suggested that you use a loader configured in context.xml: that will let you define your own ClassLoader where you can call arrayToClass at any point and not have to set the context ClassLoader all the time. If you've got something working and you're happy, then there's nothing left to do. If it were me, I'd use a custom Loader for my webapp and use Java's ObjectInputStream.

Thank you for drawing my attention to this potential issue. Perhaps I need
to verify an assumption of mine: I am thinking that since I am not using a
distributed environment there will only be one instance of this servlet.
If you want the long story: This is an intranet application and this piece
is used for sending messages to the users. As such there are other threads
that use the static methods to add messages. In the past when I had the
clients polling on an interval it would not have mattered if an instance
came or went. I will reconsider what I have done here.
What filters do you have in the request processing chain for this
servlet? Do they support Comet? (I do not remember whether it is

Thank you so much! Looking at my stack trace I saw something that made me
suspicious. The invoker servlet. I needed this as we have an mountain of
servlets that have always been called via the package name in the URL.
Once I removed this the Comet functionality worked! So I guess I will be
mapping a lot of servlets in the days to come, but it works so cool.

When we do this method, a separate web-application is spawned for each

shared. You would need to adjust PermGen - basically hike it up
appropriately. We have a similar situation. We used this approach of
putting webapp outside appbase and pointing docbase to it for each context
within individual context.xml files. The reason we did this was because we
have another default webapp serving as the root context. This is a
solution we would like to avoid.
I would like to seek advice on how we might use a non-default webapp
serving multiple contexts, but yet have a single copy of the application's
classes and it's libraries being loaded into PermGen.

Two different instances of the same webapp at different hosts - easy.

Ok, i think i've done it, namely:
* Put|log4j.jar|and|tomcat-juli-adapters.jar|from extras
into|$CATALINA_HOME/lib|. *
Replace|$CATALINA_HOME/bin/tomcat-juli.jar|with|tomcat-juli.jar|from
extras.
The problem i'm facing is that no logs are produced. At this time
i'm trying to configure just TOMCAT, no webapps, to log through
log4j but still no logs are produced. I've folowed the tutorial in
Apache logging webpage with the standard log4j.properties. No logs
in $CATALINA_BASE\logs.
Which tutorial did you follow?
The one you mentioned:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
Did you configure them to be written to ${catalina.base}/logs
? Maybe it tries to write them elsewhere?
It is configured in its standard version (
http://tomcat.apache.org/tomcat-6.0-doc/logging.html), which i am
using.
Is the file readable?
There is no file, tomcat does not create one and that is my
problem.
I think Konstantin meant is the config file readable or perhaps is
the logs/ directory writable. Of course, all permissions must be
relative to the effective uid running Tomcat.
Check catalina.out. If you don't have a log4j.properties file (or
similar) available, I believe you'll get a message on stdout saying
You haven't configured log4j properly and you won't get any further
log messages anywhere.

If you want two separate paths, you need two separate contexts.

That just doesn't make any sense. The root of a domain is, by

consider.
once again: * one webapp * has 2 different paths: /path1 and
/path2 * served on 2 domains * when user goes to

What you are saying is nonsensical (specifically, the part where you
say that you want /path1 to be mapped to root.
If you want two virtual hosts, then define two virtual hosts. If you
want an app on each host configured as ROOT, then make your two
virtual hosts have two separate appBase directories (which should be a
requirement in the first place of two virtual hosts) and toss a copy
of your WAR file in each appBase, both named ROOT.war (cApITaLS matter).
You can't deploy a single copy (in memory) of your webapp and expect
to get all your requirements above met. If you want to have a single
WAR file on the disk and deploy it multiple times, you *can* do that
but I'm not sure why anyone would want to.

Hi Hassan, I forgot to mention that I am already using Amazon's cloud (EC2+load balancer) so I love to see a suggestion that mentions it! I will definitely check your advice. The problem is that it costs money to use it, and I would love to just use some kind of framework that uses my own RAM to host a buffer/queue.

Re: Best way to log requests from a servlet and to a database?
OK, Amazon's solution would be too expensive to use as a first option. I would like to use it but just after a first queue is full.

What is ${samewebpp}/path1? Is that a piece of a webapp?
Do you care if the same webapp is deployed twice (which is probably
going to be required)?
Actually the OP is not really clear in describing anything. I'm wondering if path1 in
http://path1.com equals path1 in the
/path1 part or not.
actually the path names and domain names should be able to be different
Anyway I would say a context.xml file in conf/catalina/path1 (the
hostname)/path1.xml (the context name) should do the trick?
Place the webapp outside the appbase of the hosts and then point the docbase to
the webapp (or just drop the .war with two
different names in the appbases of the two hosts) :)
i want to have one instance of webapp,

To me it doesn't make sense to say that the webapp has two different paths,
/path1 and path2, and then say the webapp is to be
served as root from two different hosts. I guess it's simply a case of bad
terminology :)
it's not. maybe it will make things clear if i change the names of the paths,
say:
* when user goes to http://app1.com/ - {thesamewebapp}/app1 path is served as
root path of the domain app1.com
* when user goes to http://app2.com/ - {thesamewebapp}/app2 path is served as
root path of the domain app2.com
Anyway. What you are trying to do is make the same webapp answer both
domain1.com/ and domain2.com/ right? If so you can simply
deploy the webapp as ROOT. The webapp will then answer on all domains pointing
to the server. If this is not what you want, you
can set up a virtual host in server.xml with an appbase outside the webapps
folder (eg. $CATALINA_BASE (or is it HOME?)$\domain1
and then use the Alias element to specify the second domain as an alias for
the first (which you set as an attribute in the
Host element).
i know these tricks, but they don't work for my case.

Two different instances of the same webapp at different hosts - easy.
E.g. the manager webapp is deployed in such way to the virtual hosts.
One instance mapped to different paths - impossible. What value should
be returned by javax.servlet.ServletContext.getContextPath() ?
Thought it is possible to apply urlrewriting, either at HTTPD or at Tomcat.
looks like url rewriting is the only way. though i was wondering if it's
possible to do the trick with tomcat configuration.
