I don't know if you have statistics to substantiate that opinion, but it doesn't answer the question, eh? :-) There are definitely people on this list, including me, running Tomcat standalone in production. I launched few performance tests for a tomcat webapp. If you use NIO connector to exploit the CometProcessor the apache frontend has to dispatch through http_proxy module, because AJP connector doesn't offer comet feature. Anyway put apache as HTTP frontend downgrade the performance a lot. If you run tomcat with a single instance then set up tomcat straight to port 80 as you can see in this post: http://www.jroller.com/giancarlo/entry/a_brief_account_of_optimization --- http://gfrison.com - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

What kind of projects make one want to move away from normal HttpServlets and start using the NIO stuff that TC has... I understand that it gives one all sorts of async control over the servlet... but I just cant think of examples of when one would use it. Occasionally I see a question or two here, and I'm wondering what practical things designers are using these power sockets for. There are lots of articles like this one http://www.ibm.com/developerworks/library/j-nioserver/ ok, well most likely the servlet spec will one of these days introduce non blocking IO as well, but it will be while, it's a very complex programming model, and in most cases one doesn't need it. if you want async servlets (ie, decouple threads from the connection) then as Bill mentioned, Comet will do an excellent job. switching to something like the link above, you're now dealing with software outside the spec, which in some cases is not a problem, but in other cases can have consequences for a growing project, or a project that needs to be integrated elsewhere. They espouse the power side... but no concrete examples of applications... Its not like people are all diving at it... so I'm wondering if there are times when its the only way to go... Also in TC there is another APR handler, how does that relate to NIO, when will one want to use any of these over the normal, and when APR and when NIO? Just trying to understand it... practical examples sounds like a good way to start... Thanks... To give you an example of the different connectors and how they differ, in a one-to-one scenario, NIO will always be slower, since it has to do simulated blocking to accomodate the current servlet spec. When it comes to SSL, no java connector compares to the APR/OpenSSL, JSSE is simply not optimized enough (yet).

Help getting MySQL connected to Tomcat
Hello, I'm trying to get Tomcat and MySQL to connect. I have the following installations: Tomcat V5.5.26 MySQL V5.0 mysql connector 5.1.5 from the mysql site (copied the jar to tomcat\common\lib I've tried following the directions from the tomcat dist and from the mysql dist but I always get can't connect exceptions when I start tomcat. In mysql I've created a user=javauser with password=javadude and I created a database called javatest with one table and some data in the table. I can connect to the database from the console using C: mysql -u javauser -p and I can then connect to the javatest DB and select * from the table works fine. Then I added the following to in the tomcat/conf/context.xml file Context path=/db-servlet docBase=db-servlet debug=5 reloadable=true crossContext=true Resource name=jdbc/TestDB auth=Container type=javax.sql.DataSource maxActive=100 maxIdle=30 maxWait=1 username=javauser password=javadude driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/javatest/ /Context And I stop tomcat, and when I restart tomcat I get the following in the catalina log: ...
