Re: Multiple websites in tomcat
Thanks Andre. I fixed the file and now my code looks like as follows but still my servlets are not being called. 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
The good news is that you will learn more by encountering problems and solving them, than if everything worked correctly on the first pass. Ravi Sharma wrote: [...] Alias /ex /usr/java/tomcat-5.5/webapps/servlets-examples JkMount /ex/servlet/* testWorker I think that the two lines above conflict with eachother : First you are telling Apache that if it sees /ex in a URI, it should translate it to /usr/java/tomcat-5.5/webapps/servlets-examples. Then you are telling Apache that if it sees a URI like /ex/servlet/*, it should pass it to mod_jk (which will pass it to Tomcat). 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. For a bit more more information on the order in which the various request processing steps happen in Apache, read through this : http://httpd.apache.org/docs/2.2/developer/request.html For the same with pictures, try this : http://www.apachetutor.org/dev/request André - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

my mod_jk.conf looks like somthing like this: IfModule !mod_jk.c LoadModule jk_module C:/Program Files/Apache Software Foundation/Apache2.2/modules/mod_jk.so /IfModule JkWorkersFile C:/softwares/Apache/apache-tomcat-6.0.16/apache-tomcat-6.0.16/conf/jk/workers.properties JkLogFile C:/softwares/Apache/apache-tomcat-6.0.16/apache-tomcat-6.0.16/logs/mod_jk.log JkLogLevel trace I don't see any JkMount directives anywhere in the configs you posted. That's the directive that tells Apache Httpd to send requests for tomcat back to tomcat. Assuming you are mounting a webapp named examples from tomcat, the JkMount would be: JkMount/examples/* ajp13 Restarted whole thing. Still I can not go to follwoing web page. http://localhost/examples/jsp/index.html BTW, what exactly do you get instead of the page? A 404 error? Is it from Httpd or Tomcat?

Re: some concepts needed
Tomcat does have a java compiler (jasper) to compile jsp pages to servlets, but it also needs a JVM (java). Setting CLASSPATH is a big no-no. Put any required jars your webapp might need in the proper place. If you use tomcat's internal pooling for db connections, that means putting driver jar files in tomcat's lib directory. --David Deepak Mishra wrote: hi, i am pretty new to tomcat. currently i have tomcat6 on ubuntu-linux. i have pursued some books on tomcat , but they cant help me getting some concepts, they simply point to using tomcat here is one of my doubts i got during database connection.. does tomcat have its own java compiler ?

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.

Then you are telling Apache that if it sees a URI like /ex/servlet/*, it should pass it to mod_jk (which will pass it to Tomcat). 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: [OT] Performance Requirements
Thank you all for the answers and please apologize my late answer, my family obligated me to a 10 day vacation without internet... I added Franks recommendation (mainly because it was the first to come :-)) to my recommendations to the client, and we both thought them reasonable... However, now he (the client) wants to serve large video files and the whole questionnaire becomes somehow nonsensical. Nevertheless thanx very much for the replies.

Re: Multiple websites in tomcat
Do not despair. If you have removed the Alias line, it is totally normal that your first link does not work. That's because in your case that link is *supposed* to be served by Apache, but there is no file to serve at /usr/java/tomcat-5.5/webapps/servlets-examples/servlet/HelloWorldExample (and anyway, leave that Alias line out. It is not good, for reasons I will give you later). The problem is only why it does not pass the /ex/servlet/HelloWorldExample to Tomcat So, let's start from the beginning. Follow these steps, and stop whenever it does not give the expected answer. 1) verify that Tomcat, by itself, is started and listening : Your Tomcat should have a HTTP connector (probably at port 8180) You should check in the server.xml file of Tomcat. It should look approximately like this : Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=8180 minProcessors=5 maxProcessors=75 enableLookups=true acceptCount=10 debug=0 connectionTimeout=2 useURIValidationHack=false / (Look at the port=), and whenever you see below, replace it by that port number. If this connector is not activated (commented out), activate it, we will need it for the tests below. Restart Tomcat if necessary. You can check if Tomcat is listening on that port with netstat : netstat -an | grep (where is the port number above) You should see a line ending in LISTEN. 2) Try to acces that HTTP connector (from your browser) with : http://www.jaatmusic.com: (where is the same port above) You should get some standard Tomcat Welcome page. 3) Now try http://www.jaatmusic.com:/examples You should see the examples menu page 4) then, on that same page, click the link for the HelloWorld example. Does it run the HelloWorld servlet ? If yes, then go back to the menu page, and hover with the cursor above the HellowWorld example link, and note the exact URL that it shows for that link (at the bottom of your browser page). It should be something like : http://www.jaatmusic.com:/examples/HelloWorld (It is important to make sure of that, because that is the URL that Tomcat expects to run the example, even later when we will go through the mod_jk connector) 5) check if Tomcat is listening *also* on the port of your AJP connector netstat -an | grep 8009 Do you also see a LISTEN line ? (I am sure it is, because I can see it from outside. You will probably need to do someting about that later). 6) try to connect to that port with telnet : telnet www.jaatmusic.com 8009 Do you get a connection ? (if yes, try to type something, and then close the connection. Your Tomcat logs should now show something, even if it is garbage). (something like : 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 ?
