Tomcat mapping of URLs - servlets
Hi. This is a beginner-like question. I have tried to download and find this in the Servlet 2.5 Specification, but I seem to get a series of html pages describing the API, without telling me much about the general principles. So just in case this is not nicely explained in English in the spec : How does a servlet container like Tomcat map a request URI to any particular webapp ? I mean, suppose we have 3 webapps with each a servlet-mapping section, in which each time there are several url-pattern tags. I am not talking here about the strict interpretation of these url-pattern tags (although there is a question about why the servlet spec designers in their wisdom thought that they needed to invent yet another wildcard scheme). But rather, about how Tomcat takes all these servlet-mapping sections of all the servlets, and then decides, when a request comes in, to which of the servlets it attributes the request. Does it work as follows ? When the various webapps are loaded (started ?), Tomcat collects all the url-pattern's of all the webapps. It then sorts them by length (longest first), independently of the webapp from whence they come. When a request comes in, Tomcat compares the request URI with the first URL-pattern. If it matches, Tomcat delegates the request to the corresponding webapp. If not, it checks the next pattern in the table, etc.. If the request URI does not match any url-pattern, Tomcat delegates the request to the default webapp. As a corollary to the above : whenever a webapp is stopped (unloaded?) or a new webapp is started (loaded ?), Tomcat for a while stops processing new requests and rebuilds this entire sorted url-pattern matching table. As another corollary : the webapp called ROOT always has a url-pattern of /, which because it is the shortest is always at the end of the table, and thus matches anything that does not match something else ? Then, assuming the above is generaly correct, there is a remaining question about the interpretation of length in terms of a url-pattern. Such as, how is the length compared between patterns like /myservlet* and *.myservlet ?

can mod_jk detect web service unavailable
Hi: I have a JBOSS cluster which use Apache with mod_jk as HTTP load balancer. In my cluster, some nodes are deployed web service, but not all. For example, node 1 contains web servicebook_service, I can call the web service using URL http://www.node1.com/book_service;, but node 2 does not contain it. I hope mod_jk can help me to detect whether the requested web service exists. That is to say, if I call the web service using http://www.loadbalancer.com/book_service;, mod_jk can know only node 1 contains the web service and node 2 not, then the request will always be dispatched to node 1. But with my current configuration on mod_jk and Apache, I fount that the request can be dispatched to node 2. Then surely exception will be thrown, since the web service not exists on node 2. Can mod_jk support it? Do I need some specific configuration? Any suggestion from you will be very appreciated! Thanks! Zeke

mixed html and jsp site using ProxyPass
I have a site which is a mixture of html (and a bunch of images and flash and other such stuff which came in from the web designer) and a couple of JSPs. I have implemented this with Apache 2.2 and Tomcat 5.5, using ProxyPass statements with ajp in the Location tag. My location block looks like: Location / # it is the root application ProxyPass ajp://127.0.0.1:8009/jsp ProxyPassReverse http://...domain... SetOutputFilter proxy-html ProxyHTMLURLMap http://127.0.0.1:8180 http://...domain... ProxyHTMLURLMAP / http://...domain... /Location So the base stuff is at the root, and the jsp stuff is all under the jsp path element, so index.jsp is at jsp/index.jsp when referenced in a URL. There are some bits of the the Apache managed stuff (css files etc) that I need to reference in the JSP, so those are referenced as /style.css rather than style.css in the jsp pages. It would however be easier if I have the jsp code at the same level (from a URL path point of view) as the html etc files. Is there a way to divert just the .jsp files? I tried Location /*.jsp but that did not seem to work - maybe I got something else wrong. I have tried looking around with Google, but obviously I asked the wrong question as I did not find a useful answer. Any help gratefullly received.

David As another poster suggested, if the static content (CSS, images, Flash, etc) rarely changes, then make it part of your web application. You could then dispense with Apache HTTPD and AJP entirely, and have Tomcat handle the requests directly. On a Unix system, you can still run Tomcat as an unprivileged user by having it listen on ports 8080 and 8443 for example, and using firewall rules to forward incoming requests from ports 80 and 443 respectively.

Re: Tomcat mapping of URLs - servlets
André Warnier:
It appears anyway that my previous attempted logic was quite wrong.
But I still find the spec quite confusing. There is some kind of
mixture between servlet and web application that is not very clear,
at least to me.
As I understand it now, there are 2 steps :
1) the appropriate webapp (not servlet) is located using the path, not
the url-pattern
2) the appropriate servlet *within* the webapp is selected based on the
url-pattern
Yes.
Example: given the URL http://servername/foo/bar/baz/, the Container
looks at /foo/bar/baz/ to find out which webapp should handle the request.
- If there's a webapp with the context path /foo/bar/baz, that's the one
to handle the request and the path for the servlet mapping is /.
- If there's a webapp with the context path /foo/bar, that's the one to
handle the request and the path for the servlet mapping is /baz/.
- If there's a webapp with the context path /foo, that's the one to
handle the request and the path for the servlet mapping is /bar/baz/.
- If neither of the above is true, the webapp with the context path
(the default webapp, ROOT in Tomcat) is the one to handle the request
and the path for the servlet mapping is /foo/bar/baz/.
and
3) .. each webapp has a default servlet, to which things get mapped
when no other url-pattern of this webapp matches
Essentially, yes. You could comment the Default Servlet and it's mapping
in ${catalina.base}/conf/web.xml, though.
4) the ROOT webapp matches the path /, not the url-pattern /
The default webapp (named ROOT in Tomcat) matches the path . Apart
from that, what you said in 1) is true for all webapps, including the
default one.
Is the above correct ?
The confusing part for me may also be due to my misunderstanding.
I view this as follows :
- a web application is the whole thing that one finds below
(tomcat_dir)/webapps/xyz for example (including its static pages,
WEB-INF/web.xml, its servlets etc..)
- this webapp can consist of one or more servlets, each with its set of
url-pattern's that it handles
Not so ?
No, correct.
And if so, then I find the examples in table SRV.11.2.2 Example Mapping
Set quite confusing, since paths like
/foo
/bar
/catalog
would tend to imply different webapps, rather than different servlets
inside of one webapp, no ?
No. These examples talk about the mappings *inside* a webapp, i. e. what
can be used as a value for url-mapping.
In other words: the part of the request URL which is used to determine
the webapp to handle the request is already removed.
Take this trivial JSP and deploy it to different contexts/webapps. Maybe
the output will make things clearer:
html
body
table
trtdRequestURL/tdtd%= request.getRequestURL() %/td/tr
trtdRequestURI/tdtd%= request.getRequestURI() %/td/tr
trtdContextPath/tdtd%= request.getContextPath() %/td/tr
trtdServletPath/tdtd%= request.getServletPath() %/td/tr
/table
/body
/html

RE: Tomcat mapping of URLs - servlets

André Warnier:
It appears anyway that my previous attempted logic was quite wrong.
But I still find the spec quite confusing. There is some kind of
mixture between servlet and web application that is not very clear,
at least to me.
As I understand it now, there are 2 steps :
1) the appropriate webapp (not servlet) is located using the path, not
the url-pattern
2) the appropriate servlet *within* the webapp is selected based on the
url-pattern
Yes.
Example: given the URL http://servername/foo/bar/baz/, the Container
looks at /foo/bar/baz/ to find out which webapp should handle the request.
- If there's a webapp with the context path /foo/bar/baz, that's the one
to handle the request and the path for the servlet mapping is /.
- If there's a webapp with the context path /foo/bar, that's the one to
handle the request and the path for the servlet mapping is /baz/.
- If there's a webapp with the context path /foo, that's the one to
handle the request and the path for the servlet mapping is /bar/baz/.
- If neither of the above is true, the webapp with the context path
(the default webapp, ROOT in Tomcat) is the one to handle the request
and the path for the servlet mapping is /foo/bar/baz/.
and
3) .. each webapp has a default servlet, to which things get mapped
when no other url-pattern of this webapp matches
Essentially, yes. You could comment the Default Servlet and it's mapping
in ${catalina.base}/conf/web.xml, though.
4) the ROOT webapp matches the path /, not the url-pattern /
The default webapp (named ROOT in Tomcat) matches the path . Apart
from that, what you said in 1) is true for all webapps, including the
default one.
Is the above correct ?
The confusing part for me may also be due to my misunderstanding.
I view this as follows :
- a web application is the whole thing that one finds below
(tomcat_dir)/webapps/xyz for example (including its static pages,
WEB-INF/web.xml, its servlets etc..)
- this webapp can consist of one or more servlets, each with its set of
url-pattern's that it handles
Not so ?
No, correct.
And if so, then I find the examples in table SRV.11.2.2 Example Mapping
Set quite confusing, since paths like
/foo
/bar
/catalog
would tend to imply different webapps, rather than different servlets
inside of one webapp, no ?
No. These examples talk about the mappings *inside* a webapp, i. e. what
can be used as a value for url-mapping.
In other words: the part of the request URL which is used to determine
the webapp to handle the request is already removed.
Take this trivial JSP and deploy it to different contexts/webapps. Maybe
the output will make things clearer:
html
body
table
trtdRequestURL/tdtd%= request.getRequestURL() %/td/tr
trtdRequestURI/tdtd%= request.getRequestURI() %/td/tr
trtdContextPath/tdtd%= request.getContextPath() %/td/tr
trtdServletPath/tdtd%= request.getServletPath() %/td/tr
/table
/body
/html
Thanks.
Now still one more question, based upon what you wrote above :
- If there's a webapp with the context path /foo/bar/baz, that's the one
to handle the request and the path for the servlet mapping is /.
Not that I would necessarily do this, but assuming that I create the
following file structure :
(tomcat_dir)/webapps
/foo
various.jsp
WEB-INF
web.xml
/bar
various.jsp
WEB-INF
web.xml
/baz
various.jsp
and I start Tomcat.
Then I guess I have (at least) 2 webapps : a /foo webapp, and a
/foo/bar webapp.
Now a request comes in with the url /foo/bar/baz/various.jsp
How does Tomcat determine that /foo/bar/baz is not itself a webapp, but
merely a sub-dir of webapp /foo/bar ?
Or does it complain somewhere along the way ?
That may not be the right way to ask the question, so to put this
another way : when Tomcat starts, does it recurse into each webapp dir
to see if there is (for instance) another WEB-INF subdir hidden deeper
there ? Or does this information come from somewhere else ?

You probably also want to declare Size as volatile if it's going to be
accessed by multiple threads and isn't enclosed in a synchronized
method or block. You may also want to declare the argument to the setter
as final, your variable naming convention conflicts with the Sun one,
and the default constructor is redundant. I'll remove my pedant hat now.

Can mod_jk support it? Do I need some specific configuration? Any suggestion from you will be very appreciated! Only map the web service url to the nodes where it exists. Mark Thanks for the reply, Mark! But I need a more dynamic way. For example, node 1 has deployed the web service war, but it is down for some reason and can not work any more. Then the web service URL will be unavailable while the JBOSS are still running. Mapping the web service url seems can not handle it, the load balancer will still dispatch the request to node 1. I hope mod_jk can detect if the requested web service is available at runtime. Thanks! Zeke

However, it re appears when I give a different name than localhost. Finally had time to go chase this a bit more. The error doesn't really vanish when the Host name is localhost, but it is not sent to the console window Tomcat is using, nor to the catalina.*.log file; you can find it in the localhost.*.log file. When you change the Host name to something else, the error is displayed in the console window and in the catalina.*.log file, but not in localhost.*.log. The reason behind this apparently inconsistent behavior is the settings in conf/logging.properties: log entries for localhost are routed to specific handlers, which do not include the console window. When you changed the Host name but did not update logging.properties, the default log handler kicked in, which dumped the error message to the console. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: can mod_jk detect web service unavailable
Hi Zeke, You didn't say which version of JBOSS you're using, I'm assuming its a recent 4.x version that includes buddy-clustering. You're JBOSS cluster will need to be reconfigured to do what you want. The JBOSS community lists and wiki (www.jboss.org) is the best place for your question. The JBOSS community wiki has several articles on cluster configurations. cheers, --knoxy David Knox Information System Architect +1 303-748-8906 http://pragmaticis.blogspot.com On Dec 3, 2008, at 8:33 AM, Zeke wrote: Mark Thomas [EMAIL PROTECTED] wrote： Zeke wrote: Hi: I have a JBOSS cluster which use Apache with mod_jk as HTTP load balancer.

Mark Thanks for the reply, Mark! But I need a more dynamic way. For example, node 1 has deployed the web service war, but it is down for some reason and can not work any more. Then the web service URL will be unavailable while the JBOSS are still running. Mapping the web service url seems can not handle it, the load balancer will still dispatch the request to node 1. I hope mod_jk can detect if the requested web service is available at runtime. Thanks!

Session timeout related fixes between Tomcat 5.0 and Tomcat 5.5.x?
Hi, We are currently experiencing session issues with our customer's Tomcat server, in a production environment. Basically what is happening is that, despite the idle time-out being set for 20 minutes we are seeing sessions that have been idle (have not been accessed) for over 3 hours. The net result is that the Tomcat server needs to get restarted. We are currently investigating the reason why, but are currently in the dark on how we should continue our analysis. If anyone has any ideas they would be much appreciated. One parallel line of analysis is to find out if there were any fixes between 5.0.x and 5.5.x, that are related to sessions not timing out. The customer is resisting an upgrade, but if we can show that there have been session related fixes, then this could help our case. If there have been none, then we will simply have to focus purely on the web application. Any help would be appreciated.

Do you have keep alives enabled? Look at the maxKeepAliveRequests attribute: http://tomcat.apache.org/tomcat-5.5-doc/config/http.html#Standard%20Implementation Is your webapp caching sessions for any reason? Can you implement a SessionListener to see if expiration events are occurring? The net result is that the Tomcat server needs to get restarted. Why? Are you running out of heap space? Do you have a memory leak elsewhere as well? One parallel line of analysis is to find out if there were any fixes between 5.0.x and 5.5.x, that are related to sessions not timing out. The changelog is here for your perusal: http://tomcat.apache.org/tomcat-5.5-doc/changelog.html I have implemented a session listener and also activated access logs. The session listener adds a list with sessionCreated() and removes them with sessionDestroyed(). I then have a JSP that displays the list, along with when the session was created, using getCreationTime(), and when the session was last accessed, using getLastAccessedTime(). If a session has already been invalidated by the container I will get a IllegalStateException when I call getCreationTime() on the session I am getting the information from. An example output of my tool is: sessioninfo count=581 maxLife=657.410 maxIdle=636.710 session id=54D57E020A2791CDDDE6307E7565C328 life=657.410 idle=632.789 / session id=6EE000B43250CC6CEDCD3B2D95A5A79B life=657.039 idle=616.064 / session id=8CE0C68E1098C291D69F70FEB4EFC631 life=641.774 idle=636.710 / session id=10C182293F0CBA68291AF2C439E6058A life=104.579 idle=65.900 / session id=F62A60B0037D09D44B7F27E549A4D6B1 life=104.336 idle=74.971 / session id=CAC0CA3066737D8316CBABB7E960EDBC life=104.195 idle=98.052 / session id=FD8CCFF63428DE1C50A668DF27C2865D life=103.911 idle=64.812 / session id=874032F034F3E12C911C9152632C5D7D life=101.407 idle=99.031 / /sessioninfo - life is current time - creation time. - idle is current time - last accessed time. When I speak to our operations team they tell me that the server crashes because it is unable to create any more sessions, so it is possible we are out of heap space. The logs show me that at least half of the sessions are idle for more than 30min. I could probably add more information to the tool to display memory usage. The other issue is that we are having trouble reproducing this in a development environment, so it is making our life just a bit harder. The changelog that you pointed me to only seems to cover changes from 5.5 onwards. There is nothing there covering 5.x previous to that. Are there any older logs available anywhere?

Unable to connect to DB using DataSource
Hello list.
I am trying to use a JDBC DataSource to connect to a PostgreSQL server
from within an Axis WebService running in Tomcat.
What confuses me is that I managed to get this to work on one server,
but now am failing miserably to do so on a second server.
The first server is a Debian Lenny with Tomcat 5.5 and Axis 1.4.1,
running in a Xen DomU on a 64 bit AMD machine.
The second server is also running Lenny with the same Tomcat and Axis
versions, but in a VirtualBox VM on a 32 bit Intel machine.
I have compared the whole directory tree of /var/lib/tomcat5.5, also
/usr/share/java, /etc/default/tomcat5.5 and the startup scripts in
/etc/init.d/tomcat5.5.
Everything is identical between the two servers, and still, #1 works, #2
doesn't.
The error message tells me that it can't find the postgres JDBC driver.
However, there is a symbolic link in /var/lib/tomcat5.5/share/lib
pointing to the driver in /usr/share/java. Also, I tried to open a
connection directly, that is, using DriverManager.getConnection(),
it works, so it seems to be able to find the driver.
This is the configuration of the DataSource (in
/var/lib/tomcat5.5/conf/server.xml):
Context path=/axis2 reloadable=true cachingAllowed=false
Resource name=jdbc/pigaiadb auth=Container
type=javax.sql.DataSource
maxActive=100 maxIdle=10 maxWait=1000
removeAbandoned=true removeAbandonedTimeout=60
username=user password=password
driverClassName=org.postgresql.Driver
validationQuery=select 1
url=jdbc:postgresql://localhost/database /
/Context
This is how I access the DataSource in the Axis WebService's LifeCycle
object startup routine:
public void startUp(ConfigurationContext configctx, AxisService
service) {
Context initCtx = null;
Context envCtx = null;
DataSource ds = null;
try {
initCtx = new InitialContext();
} catch (NamingException e) {
LOG.error(InitContext Exception : + e.getMessage());
}
try {
envCtx = (Context) initCtx.lookup(java:comp/env);
} catch (NamingException e) {
LOG.error(envContext Exception : + e.getMessage());
}
try {
ds = (DataSource) envCtx.lookup(jdbc/pigaiadb);
} catch (NamingException e) {
LOG.error(DataSource Exception : + e.getMessage());
}
try {
service.addParameter(new Parameter(Constants.DATASOURCE, ds));
} catch (AxisFault e) {
LOG.error(Failed to add datasource parameter to context:
+ e.getMessage());
}
}
And this is how I try to get the connection from the DataSource:
try {
conn = ((DataSource)
serviceContext.getAxisService().getParameterValue(Constants.DATASOURCE)).getConnection();
} catch (SQLException e) {
LOG.error(SQLException while trying to get connection :
+ e.getMessage());
}
... which results in the following error message:
SQLException while trying to get connection : Cannot load JDBC
driver class 'org.postgresql.Driver'
and this stack trace:
java.lang.ClassNotFoundException: org.postgresql.Driver
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:1130)
at
org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.java:880)
...
Replacing above code with the following works without errors:
try
{
Class.forName(org.postgresql.Driver);
conn =
DriverManager.getConnection(jdbc:postgresql://localhost/database,
user, password);
}catch (Exception e) {
LOG.error(SQLException while trying to get connection:
+ e.getMessage());
}
This is my first project with Tomcat, Axis, JDBC and PostgreSQL, and
also the first time I'm seriously using Java in a very long time,
so please have some patience with me if I'm missing something essential
here. I would greatly appreciate some pointers as to how I
could nail down this problem. How comes Class.forName works when I call
it directly, but not when the DataSource class calls it internally?
Thanks a lot in advance

Unable to stop SimpleTcpReplicationManager
Hi all, I'm having two Tomcats which are placed in a cluster. If I stop and start a context (instead of completely stopping/restarting Tomcat), then I see the following error in catalina.out: ERROR: Unable to stop SimpleTcpReplicationManager No other information is specified. I have been Googling, but haven't found any explanation. I took a look at the source code of the SimpleTcpReplicationManager, but I can't derive from it what could have gone wrong. When I try to restart the context, then I see the following error: ERROR: Starting... no cluster associated with this context:/dist/preproduction/wasuzi I'm guessing the latter error is related to the first one. Unfortunately, right now I don't have access to the server.xml to post the configuration info. In a couple of hours I will, but I thought I'd give a heads up, just in case anybody has seen this error before. Before I forget, when I stop/start Tomcat completely, I don't see this error, it's only happening when reloading a context. Thanks.

RE: Tomcat 6.0.18 Servlet Loading/Reloading
I've been doing some more testing and added a bunch of System.out.println statements to the init, init(ServletConfig), and doPost/doGet methods so that I could see what my application was doing without log4j initialized. Basically when I restart Tomcat, it doesn't call any of the init methods of the Servlet, however it does load it partially. When I actually browse to the URL of the Servlet, I can see my System.out.println statements being output to catalina.out, however all of the initialization which was to be performed by the init methods was never done. When I copy the existing war file from the webapps directory to another location, update the modify timestamp and then move it back into the webapps directory, the init methods are then called and the application works properly.

RE: Tomcat 6.0.18 Servlet Loading/Reloading
From: Justin Randall [mailto:[EMAIL PROTECTED] Subject: RE: Tomcat 6.0.18 Servlet Loading/Reloading Basically when I restart Tomcat, it doesn't call any of the init methods of the Servlet Unless you have load-on-startup set for the servlet in your webapp's WEB-INF/web.xml, that is correct behavior for a Tomcat restart. The init() method (there can only be one per servlet) should be called upon first reference to a URL that matches a url-pattern element inside one of your servlet-mapping elements. If load-on-startup is set, the init() method will be called at Tomcat restart for each such servlet. however all of the initialization which was to be performed by the init methods was never done. You keep using the word methods when there is only one init() method for a given servlet; why is that? When I copy the existing war file from the webapps directory to another location, update the modify timestamp and then move it back into the webapps directory, the init methods are then called and the application works properly. This is also correct behavior for initial or re-deployment. Although the spec doesn't require it, Tomcat calls the init() methods to verify webapp viability at these times. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: JK Connector problem
Hi, I solved the problem. Actually it was a silly mistake in the configuration. I was using a folder name with spaces and without putting it inside a double quote. Now it is working fine.

Pointing domain to a context in tomcat
Hi all, I have recently started using Apache web server with Tomcat. I need to have something like this: www.mydomain.com maps to something like www.mydomain.com:8080/mycontext With the help of mod_jk i am now able to achieve www.mydomain.com/mycontext. I want to be able to have www.mydomain.com i.e. user should not even specify the context and the apache server should map to my context. I searched the net and was told that mod_rewrite can be used with PL flag. But since I am new to configuration, I could not figure out how to use that for my purpose. Also, If I user mod_rewrite then /mycontext will be visible in the address bar. I am more in the favor of a solution in which /mycontext is not at all visible. Any help will be much appreciated. regards, nitin -- View this message in context: http://www.nabble.com/Pointing-domain-to-a-context-in-tomcat-tp20828588p20828588.html Sent from the Tomcat - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
