Running schduled jobs
Hi All, I need to run some threads at particular time during the day, does Tomcat provide any such facility? If not then whats the other best way to go for it. Basically i recalculate my site's visitor data every 30 minute and keep in cahce and then display to users, 30 minute delay for my data is fine but atleast i dont need to run queries to find those data for each request. Now every 30 minute i want to run those query and update the cache. How can i achive it.? Thanks, Ravi.
Filtering URL via tomcat
Hi All,
Please help me for this problem, i am not able to get to the root of the
problem.
My site have few open/free pages which can be accessed by anyone/guests and
few only for registered users. So you can access those pages only by login
to the site
http://www.mysiste.com/audio/abc.html (anyone/guests can see this page)
http://www.mysiste.com/audio/app/download/abc.html (only logged in user can
see this page)
I am using tomcat 5.5 and appache httpd server 2.2.
the root of my site reside in appache httpd server
so i have folder structure like
mysite/public_html/audio
mysite/public_html/app/audio/download
in my httpd conf i have something like this
JkMount /app/audio/download/* ajp13w
..
..
..
and mysite.com is poiniting to mysite/public_html
*app* is my tomcat application context
and in tomcat web.xml one Filter is listning to url
filter
filter-nameDownLoadSecurityFilter/filter-name
filter-classcom.app.security.SecurityFilter/filter-class
/filter
filter-mapping
filter-nameDownLoadSecurityFilter/filter-name
url-pattern/audio/download/*/url-pattern
/filter-mapping
So all the pages will be served by apache httpd except the pages which are
like app/audio/download.
So now when somone try to access app/audio/download/some.html the request
passed to tomcat, in turns filter check this url and if user is not logged
in then login screen comes up.
User login and proceed and login screen automcatically forward the request
to the page which was requested app/audio/download/some.html, but here i get
this tomcat error
*Type* Status report
*message* */app/audio/download/some.html*
*description* *The requested resource (/app/audio/download/some.html) is not
available.*
these html pages are static pages and exists in apache http home dir of
websites
public_html/app/audio/download/some.html
but then i thought may be it need to exists in tomcat web apps too., so
under web-apps/app dir i created audio link to audio directory under
public_html
so now webapps dir has following link
webapps/app/audio - /home/mysite/public_html/audio
so basically if i try to access any thing with
http://www.mysite.com/app/audio, it should be served from audio dir in
webapps which in turn audio dir from appache httpd.
But its not working. :(
I dont know whats wrong.
following is my java filter class
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
throws IOException, ServletException {
try
{
checkSecurity(request);
}
catch(UserNotLoggedIn ex)
{
httpResponse.sendRedirect(httpRequest.getContextPath() +
LOGINURL +?URL= + targetUrl);
return;
}
catch(OperationNotAllowedForUser ex)
{
httpResponse.sendRedirect(httpRequest.getContextPath() +
DENIENDURL );
return;
}
chain.doFilter(request, response);
doAfterProcessing(request, response);
}
private void doAfterProcessing(ServletRequest request, ServletResponse
response)
throws IOException, ServletException {
}
Thanks in advance

its not working is not something that allows anyone to help you.
HOW is it not working ? What do you do, what do you expect, and what are
you getting as an error ?
That means :
- tell us what URL you are using in the browser
- what error do you see in the browser ?
- what error do you see in the Apache logfile ?
- and what error do you see in the Tomcat logfile ?
Then (old African proverb) : if you want to eat an elephant, you should do
it a little bit at a time.
In other words, simplify the problem if you can.
Assuming that your Tomcat listens on port 8080 for example (you can see
that in the conf/server.xml, Connector tags), try the following :
- turn off Apache httpd
- in the browser, enter the URL
http://www.mysiste.com:8080/app/audio/download/abc.html
(that goes to Tomcat directly, without going through Apache).
What happens then ?
Don't be afraid to add some details.

I have been looking into memory profiling to help me find the leak but nothing seems to be or do what I need. Simply put I want a list of all of the objects/primitives (and if possible their values) that are in memory. It would be really nice if I didn't have to bring Tomcat down at all to do this analysis as the servlet is running in a production environment. Does anyone know of a decent free tool that does such a thing? If not, what would be a good route to take to find this leak? Thanks a ton. I just finished debugging a major memory leak in my servlet application. Try running the tool jmap that comes with java. It works great with Tomcat - just find the PID of the Tomcat (java) instance and run it on that. For example, fire up Windows Task Manager, go to Applications and find Tomcat. Right-click and choose go to process. This will move you to the Process pane highlighting the Tomcat (java) process ID. Now open a command (console) window and (assuming you have Java paths set correctly), type: jmap -histo PID output.txt (or output.txt - although I used sequentially numbered output files) This will capture the stack info into a file for analysis. The PID is the process ID you noted from the Task Manager. If you run this just after you start Tomcat, then a few times after doing the things that you suspect trigger the memory leak, you should see objects in the map that you can identify as not getting released and thus zero in on the leak.

Redirection
Hi, I have the following scenerio. I have a site which provide music online. Now for hosting the actual song i have purchased another site with better band widthm but no tomcat. So my webserver(tomcat) is running on one server(say domain1) and files are hosted on another (with different domain name say domain2, which anyone can access using http). Now i have to put http://domain2/abc.music on my site to access these files. Now i can do something like that write a normal Servlet which receive song id and i forward it to appropriate link(http link to another site domain2). but when someone start downloading they see that data is coming from domain2, i dont want user to see domain2, and also i can not do somethin like when user request any file first get it on to domain1 server and then provide it to user as it will be too much bandwidth wastage. So is there any way to do this using anything in apache,tomcat to hide domain2 from everyone., Thanks, Ravi.

Re: receiving 404 page not found from godaddy.com
Hi I have tried godaddy's Shared hosting and i had the sme problem and they gave me the same answer that upgrade to dedicated server, so then i though i will try something. first of all they are still using tomcat 4.4.x something and java 1.4(or may be 1.3 i dont remember properly), so first create that environment on ur pc and test it an then upload it. i was able to run index.jsp which was just pure jsp, but my other pages didnt work as i was using Spring framework they were giving the same error page not found, and reason is that because of old java version they are not able to support spring framework. So i had to leave the godaddy Shared hosting and when i did RD for dedicated servers, again i landed buying Godaddy's virtual dedictaed Server(they were better then other provider in terms of money as well as the server configuration they were providing). Now i am quite happy with it. Best of luck with godaddy's shared hosting deployment and stupid Technical support on it. Thanks, Ravi.

Basically apache is not passing requests to tomcat, only Alias is working but not JkMount *So now my worker's file looks like this, i added testWorker* worker.list=wlb,jkstatus,testWorker worker.testWorker.type=ajp13 worker.testWorker.host=localhost worker.testWorker.port=8009 worker.ajp13w.type=ajp13 worker.ajp13w.host=localhost worker.ajp13w.port=8010 worker.wlb.type=lb worker.wlb.balance_workers=ajp13w worker.jkstatus.type=status *My Server.xml of Tomcat looks like this* Connector className=org.apache.ajp.tomcat4.Ajp13Connector port=8009 minProcessors=5 maxProcessors=75 acceptCount=10 debug=0/ *jk.conf loks like this(its in conf.d dir) * LoadModule jk_module modules/mod_jk.so JkWorkersFile /etc/httpd/conf/workers.properties *and httpd.conf looks like this * Include conf.d/*.conf JkLogFile libexec/mod_jk.log JkLogLevel debug Alias /ex /usr/java/tomcat-5.5/webapps/servlets-examples JkMount /ex/servlet/* testWorker JkMount /temp/*.jsp testWorker Location /usr/java/tomcat-5.5/webapps/examples/WEB-INF/ AllowOverride None deny from all /Location *Still a Problem* When i access www.jaatmusic.com/ex http://www.jaatmusic.com/ex(try this link please), it shows me the index page of my application(servlet-example) which is a index.html page.So this step work fine. That means it usage the Alias thing(Alias /ex /usr/java/tomcat-5.5/webapps/servlets-examples) Now from this page there are links to invoke some servlet examples http://www.jaatmusic.com/ex/servlet/HelloWorldExample, this link doesn't work. As per my understanding it should have worked because of this line - *JkMount /ex/servlet/* testWorker* When i access above link i got follwoing in apache log files *file not exists usr/java/tomcat-5.5/webapps/servlets-examples/servlet, referer: http://www.jaatmusic.com/ex/ * and jk mod log says * missing uri map for jaatmusic.com:/ex/servlet/HelloWorldExample* but i have defined it *JkMount /ex/servlet/* testWorker *and there is no log in tomcat as tomcat has not been hit. i dont know what i am missing everything seems to be ok now but still not working also in my web.xml servlet is defined like this servlet servlet-nameHelloWorldExample/servlet-name servlet-classHelloWorldExample/servlet-class /servlet servlet-mapping servlet-nameHelloWorldExample/servlet-name url-pattern*/servlet/HelloWorldExample*/url-pattern /servlet-mapping Please help.

Maybe you want to change these 3 lines to worker.testWorker.type=ajp13 worker.testWorker.host=localhost worker.testWorker.port=8009 and try again ? Personally, I would also change this : Location /examples/WEB-INF/ AllowOverride None deny from all /Location to this : Directory /var/www/xyz/examples/WEB-INF (*) Order allow,deny deny from all /Directory (*) replace this by the real disk path to WEB-INF the reason being that, if you are under Windows e.g., someone requesting the URI /examples/web-inf would get to the directory, because it does not match exactly the Location, and for Windows the directory path is case-insensitive, so Apache will serve it.

Re: Multiple websites in tomcat
ya thats true propblems gives u more knowledge..but this one is killing me :) i have removed the alias line too. now none of the link is working :( I dont know whats wrong now httpd.conf has only this line JkMount /ex/servlet/HelloWorldExample testWorker. I really dont know what i am missing... please help.

Here is my guess as to what happens, step by step : You send the following request to Apache : /ex/servlet/HelloWorldExample Because of the Alias, Apache will first translate this to the file location /usr/java/tomcat-5.5/webapps/servlets-examples/HelloWorldExample Then Apache will try to find a handler for that location. Because mod_jk is installed, Apache will ask mod_jk if it is interested in this URI. mod_jk will say no, because the above translated URI does not match /ex/servlet/* in the JkMount. So mod_jk will return DECLINED to Apache. Then Apache will ask other possible handlers, and if nobody else wants this URI, then Apache will select its own default handler (the one which just returns local files). This default handler will try to find the file /usr/java/tomcat-5.5/webapps/servlets-examples/HelloWorldExample and will not find it. So it will return an error. The point is that an Alias happens earlier in the cycle of processing the request (the URI translation step), and the content generation step happens later. mod_jk (and Tomcat) are involved in the content-generation phase. But by the time mod_jk is getting asked if it wants to generate the content, the URI is already tanslated, and mod_jk does not recognise it. In short, for a test of the above, comment out the Alias line, restart Apache, and try again the URL http://www.jaatmusic.com/ex/servlet/HelloWorldExample Of course, with the above change, your first URL http://www.jaatmusic.com/ex will probably not work anymore, but that is normal and we will see that next.

Re: Multiple websites in tomcat
: 2008-07-21 00:29:44 Ajp13Processor[8010][5] [Ajp13] incomplete read, waited #-1 got only 0 ) If all the above is ok, then Tomcat should be fine, and we can go back and check the Apache side. 7) replace your JkMount line in Apache by these 2 lines : JkMount /examples testWorker JkMount /examples/* testWorker and restart Apache 8) enter http://www.jaatmusic.com/examples (notice that this time you are *not* entering the port , because you want to connect through Apache, not go directly to Tomcat). Do you see the same Tomcat examples menu page as before ? If not, what do you see ? an error page of Apache, or one of Tomcat ?

Thanks, Ravi.

Re: Multiple websites in tomcat
Hi Rainer, Thanks, i checked in included files and found that it was already declared in one of included conf file. Thanks for pointing me that.Now i have corrected it and server is starting properly with following warnings which i am skipping as of now. [Sat Jul 19 10:59:41 2008] [warn] module jk_module is already loaded, skipping [Sat Jul 19 10:59:41 2008] [warn] Useless use of AllowOverride in line 1000.
