Covalent FastStart 3.1 freshly installed ---------------------------------------- ./covalent/servers/server-name/conf/httpsd.conf 1) modify prefork.c tag to be <IfModule prefork.c> StartServers 5 MinSpareServers 55 #MinSpareServers 5 MaxSpareServers 250 #MaxSpareServers 10 MaxClients 256 #MaxClients 150 MaxRequestsPerChild 0 </IfModule>
2) change Apache http request port if needed Listen 8080 3) modify Document Root and add matching <Directory> tag with location of ui install DocumentRoot "/home/willkok/lnie" <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory "/home/willkok/lnie"> </Directory> 4) to <IfModule mod_jk.c> add these tags with the UI location #Mount lnie JkMount /lnie/*.jsp loadbalancer JkMount /lnie/* loadbalancer # # The following line makes apache aware of the location of the /lnie context # Alias /lnie /home/willkok/covalent/lnie <Directory "/home/willkok/covalent/lnie"> <IfModule covalent_usertrack.c> EnableLocationTracking off </IfModule> </Directory> # # The following line prohibits users from directly accessing WEB-INF # <Directory "/home/willkok/covalent/lnie/WEB-INF/"> AllowOverride None deny from all </Directory> in ./covalent/servers/server-name/conf/workers.properties 1) change workers.list line to worker.list=tomcat1,tomcat2,tomcat3,loadbalancer 2) remove all worker.ajp13 lines 3) add the following modifying ports as needed worker.tomcat1.port=8019 worker.tomcat1.host=localhost worker.tomcat1.type=ajp13 worker.tomcat1.lbfactor=1 worker.tomcat2.port=8029 worker.tomcat2.host=localhost worker.tomcat2.type=ajp13 worker.tomcat2.lbfactor=1 worker.tomcat3.port=8009 worker.tomcat3.host=localhost worker.tomcat3.type=ajp13 worker.tomcat3.lbfactor=1 4) uncomment this line worker.loadbalancer.type=lb 5) replace worker.loadbalancer line with worker.loadbalancer.balanced_workers=tomcat1,tomcat2,tomcat3 copy ./covalent/servers/server-name/conf/server.xml to ./covalent/servers/server-name/conf/server1.xml ./covalent/servers/server-name/conf/server2.xml ./covalent/servers/server-name/conf/server3.xml 1) in server1.xml modify the shutdown port setting to an open port <Server port="8015" shutdown="SHUTDOWN" debug="0"> 2) modify the running port setting for an open port <Connector className="org.apache.ajp.tomcat4.Ajp13Connector" port="8019" minProcessors="15" maxProcessors="1500" acceptCount="50" debug="0"/>
3) add a jvmRoute to the engine tag <Engine jvmRoute="tomcat1" name="Standalone" defaultHost="localhost" debug="0">
4) add a context tag for the ui code location below the examples context tag <Context path="/lnie" docBase="/home/willkok/lnie" />
5) repeat steps for server2.xml and server3.xml changing port numbers to other values and the jvmPath to "tomcat2" and "tomcat3" respectivly
copy ./covalent/servers/server-name/bin/tomcat_startup.sh to ./covalent/servers/server-name/bin/tomcat_startup1.sh ./covalent/servers/server-name/bin/tomcat_startup2.sh ./covalent/servers/server-name/bin/tomcat_startup3.sh
1) in tomcat_startup1.sh a. Replace all occurences of server.xml with server1.xml b. Replace all occurences of jvm.stdout with jvm1.stdout c. Replace all occurences of tomcat.pid with tomcat1.pid 2) do the same for tomcat_startup2.sh and tomcat_startup3.sh to start apache and tomcat's ./covalent/servers/server-name/bin/apache_startup.sh start ./covalent/servers/server-name/bin/tomcat_startup1.sh start ./covalent/servers/server-name/bin/tomcat_startup2.sh start ./covalent/servers/server-name/bin/tomcat_startup3.sh start stop to stop

Is this book about servlet applications or does it discuss the internal details of Apache implementation?
Hello, I've used Tomcat and Resin for quite some time and find it distressing that I have to restart Tomcat every time I change a class. Is there a way around this so that Tomcat automatically compiles and/or reloads the class (liek Resin) when it detects a change? I've read about a "reload" attribute and find that it does pickup the change, however, when you hit a servlet/JSP file that hits the changed code, Tomcat dies. Am I missing something in the configuration?

Thanks a lot Willkomm, I would like to give a try soon.

yes it should but it would be easier if you know a bit about java.

its not about servlet apps and it only discusses the internals of apache in architectural detail so long as this helps you to administrate the server - the book is primarily about administrating tomcat

Sometimes Tomcat dies when it sees bad server.xml. Try this: <Context path="/report" docBase="c:\mrc\webapps\report" debug="0" reloadable="true" />

One of the most annoying things about servlet development is that it is very time consuming. Stop server, modify class file, run ant, start server. One thing I noticed is that if you do not follow the dtd in web.xml, you will get "resource unavailable sc404 from TC." I am getting more comfortable with web.xml, so I can spot my error quickly, but still, it would be nice to have an error for this, such as a SAXParseException pointing to the line number in web.xml, displayed right in the browser. Is there a way to find those errors through logging? How can I use logging to streamline the development process? Garrett
I agree with you- and apparently so did the Tomcat 4.1 developers! The manager application in Tomcat 4.1 allows manager commands to be run from an ant script. You can now use ant to build, install and then reload a web application. This allows for a very integrated develop-deploy-test cycle and is discussed in some length in the book. See the "Managing Applications with Ant" section in the sample chapter. http://www.wrox.com/books/sample-chapters/SampleChapter_1861007736.pdf The uses of ant in conjuntion with Tomcat is discussed in more detail in a later chapter in the book. - Vivek

Hi Have any one of you tried the connection pooling in Tomcat 4.1.12 and Oracle 8.1.7. I followed the JNDI How to tutorial in the Jakarta Apache site. I am getting Unable to load driver ' null ' error . Can any one suggest me any tips.

Hi all, I am wondering how Tomcat would support Web services development?

Tomacat 4.0.1 does not handle the combination of FORM-base authentication and a constraint on the HTTP POST method for a resource correctly. It authenticates the user as expected but call the doGet() method on the resource instead of doPost() i.e. if you use the FORM-base auhentication and submit the FORM Tomcat calls doGet() method This combination works well in the Weblogic Application Server. I want to know more about this and how could this differences about security i get the reply like call doPost from doGet it just like hook and crook. van i adjust in configeration some way which we slove this prob or tell some other way.

Web Services!. Apache provides implementation of SOAP through AXIS. Axis can be easily configured to Tomcat by just adding a axis folder to tomcat webapps, for more information please visit http://xml.apache.org/axis/index.html Regards Balaji
