The idea is ever use a static method to deal with static variables.

Re: Redirection from http-server
If you we're in Tomcat, you could use "Request Dispatch", but it seems that you have your own http server, thus you should use the code of TCP/IP protocol appropriate, that is, a code and the url (http://someThing:8080). sincerely, Zenon Farias Braga F. >From: "Subbarao Bhagavati" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: [EMAIL PROTECTED] >Subject: Redirection from http-server >Date: Tue, 13 Mar 2001 20:22:03 -0500 > >Hi, > >I have written a simple http server that can serve static content.

RE: Why we need apache web server with tomcat
I don't know, perhaps if dns had an alternative to redirect some domain
("http://www.something.com") to port 8080, them the only need to use apache
would be performance, thus for simplicity, I think that only Tomcat could
work fine, but how many times does apache do the work in static page
compared to Tomcat? And if I'm use apache and use some perl script like
modjk that uses an interpreted language, that as we already know isn't fast,
does the overall time of serving static and dinamic pages using apache be
less than the overall time of serving static and dinamic pages using Tomcat?
You should consider that redirecting a page has some overhead, and many
time when the two servers isn't so coupled, it has some increase in trafic.

Re: 'work' Folder--help??
I'm not sure, but the work directory is for hold the servlet's that the jsp generates, that is, before any jsp works, it need to generate a servlet, and the code of this servlet is hold in work directory. sincerely, Zenon Farias Braga F. >From: "Mick Sullivan" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: [EMAIL PROTECTED] >Subject: 'work' Folder--help?? >Date: Wed, 14 Mar 2001 23:11:12 - > >Hi >Anyone know what the hell is the 'work' folder for?? >Ive been using Tomcat for a couple of months and just today my project is >gone all screwed up and when I make changes to the .JSP pages, they dont >update on the server.

Re: Reloading Pages....Help
I'm not sure, but every jsp generates a servlet in work directory and these servlets are erased when you invoke shutdown.sh, thus the simplest thing to do is to invoke shutdown.sh and then startup.sh, and the second simplest thing to do is to go to work directory and "rm *". sincerely, Zenon Farias Braga F. >From: "Mick Sullivan" <[EMAIL PROTECTED]> >Reply-To: [EMAIL PROTECTED] >To: [EMAIL PROTECTED] >Subject: Reloading PagesHelp >Date: Wed, 14 Mar 2001 16:47:32 - > >Hi >I need some help here.

Re: Closing ResultSet and Statement?
I'm not sure, but I think that you don't close a ResultSet, you only close
the connection, in fact, you can even close the connection and still work
with your ResultSet.
Think of ResultSet like a normal class with an interator that allows you to
go forward and backward.

You can use a servlet using jdbc, specifically jdbc-odbc bridge, appart it you have to configure ODBC for access.

Make your Servlets using packages, compile everything from the directory one degree above in the tree (the directory that your subdirectory is connect). Use web.xml in your context (under WEB-INF) and put: somethingthatusespackage nameOfPackage.SomeThingThatUsesPackage somethingthatusespackage /somethingthatusespackage That is it, whem your start Tomcat and Netscape and put "http://127.0.0.1:8080/yourcontext/somethingthatusespackage" your servlet that would be in "/opt/tomcat/webapps/yourcontext/WEB-INF/classes/nameOfPackage/SomeThingThatUsesPackage.class" will be loaded. > >I need the answers ASAP and I will be more than thankful to have them, >Thank you very very much, >Yaron Klein. > >- >To unsubscribe, e-mail: [EMAIL PROTECTED] >For additional commands, email: [EMAIL PROTECTED] > _ Get your FREE download of MSN Explorer at http://explorer.msn.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
