Re: Database connection Pool in Tomcat
You can also try PoolMan (forgot the URL). You just use jdbc:poolman://yourdatabase instead of the real url. Configure poolman using the poolman.xml code the program as you normally do without a connection pool or cache. when you do someConnection.close() instead of closing it just returns it to the pool.

Re: MD5 example
First, MD5 and SHA are in the java.security.* package! And about decrypting MD5's -- MD5 is a one way function so you can not decrypt it or reverse it. To compare the password. Encode the password and compare with the prestored digest. What is an one way function? Well, if I take 531 then generate a digest 5 + 3 + 1, I will get 9. However, from 9 I can not tell what were the numbers used to generate it. Or how many numbers were there. MD5 is similar. It generates a 16 byte digest (number) for any set of bytes. The only difference is that it is pretty unique unlike my example where 5+1+1+2 would also have generated 9. Hope that helps!

Re: AutoRefresh
If you mean refreshing the client's page without using the refresh meta-tag, I think a simple solution might be to use an applet. A simple applet with a ServerSocket on particular port. When the database is changed, the server sends a message to the applet which tells the browser to refresh the page. Alternatively, the applet can periodically check if the database has been modified and then request the page. I would prefer to have a single thread checking for database modification and all change listening applets register with it so multiple copies of the same query are not run on the database.

Re: sql server insert
Here is something from the list archive Use java.sql.PreparedStatement for creating and executing your queries. PreparedStatements are simple to use ; they're like template SQL strings with ? symbols marking all your changeable values to include in the SQL statement. After creating the PreparedStatement based on the template, use its "set...()" methods (such as "setString()", "setInt()") to replace the ? symbols with your values. This avoids worrying about character encodings, data formats, and enclosing strings with quotes. However, your JDBC driver and database must also be able to handle such characters... the Java language can, but it depends on everything else in your system. Just try it if you can! You should be able to construct test strings by using an input method editor, or by creating strings based on Unicode characters (based on numeric escape codes such as \u1234 if necessary) in JavaScript or by "pre-filling" your HTML with characters appropriate for your locale. -Chris Re: Internationalization Issue Date: Mon, 20 Aug 2001 15:04:10 +0200 From: chris brown <[EMAIL PROTECTED]> === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Re: Bulk Printing from JSP's???
For our project, we have two methods. When a user generates single bill we use the browser to print it. The browser handles everything. When we need to do bulk printing, the stored procedure in database generates the bills as text files in a temporary directory. The text files are printed with a Java servlet in the background. Actually, once the text files are generated any method can be used to print them. The files are deleted once the printing is finished. It works fine for us as we do not have any graphics or fancy fonts in our bill. If you want to use graphics and fonts may be you could try generating pdfs and getting another program to print it? Of course, there is still the option of writing your own print engine in Java using Graphics2D.

Re: Logout problem...
Let's go over an example. You login with login.jsp you are authenticated with authenticate.jsp then it sends you to loggedin.jsp at the end you go to login.jsp when you log out. assumptions: 1. you are doing session.invalidate() in login.jsp 2. you want to be "efficient" and are using tag. for example authenticate.jsp send to loggedin.jsp using or you are always in authenticate.jsp and you use to include the relevant page. A controller! what is most probably your problem: after you have logged out, does pressing the back button send you to authenticate.jsp? if it does, then the browser is resending your login information (with or without asking you depending on the browser) and reauthenticating you. solution: instead of use response.sendRedirect() to send from authenticate.jsp to loggedin.jsp basically, ensure that authenticate.jsp is never displayed on the url textbox of the browser so that the browser does not automatically reauthenticate you. when you manually type authenticate.jsp on the browser's url textbox there is no problem as you don't have the login information. however, browser tend to remember the information used to get a page and can repost the same information. ---- hope this helps!

You could just have a method called setConnection(Connection c) in your beans. b. You can have a HttpSessionBindingListener to ensure that all Connections are closed when the session terminates by either user logging out or session timing out. I have seen a lot of code and books doing the second way. Yet, I myself am using the first method most of the time because I like to design my webapps such that the beans hide all the info about the database from my jsp pages. The beans act as a layer between the database (or any other information source) and the jsp pages. For the actual database connection, I use PoolMan to pool and cache my interactions with the database.

We have made this a background servlet that loads when Tomcat is started. We develop in Linux and deploy in Solaris. We have made Tomcat a daemon by starting it from the rc.local file.

Re: Platform choice advice for deploying a website
Hi, We have about 90% dynamic and 10% static content(few help pages and mostly images). Yet we are using Apache + Tomcat 3.2.3. Why? Well, our site is access with SSL (https) only. Though we did not test it to verify, we were told that SSL in native library is faster than Java. Basically, Apache provides us with a native SSL library with OpenSSL + mod_ssl so that we can avoid that in Tomcat which would use a Java version. May be once we pass the acceptance test and have more time we will actually measure it. If anyone has done it do let us know.

Re: Iterator.next to String
If you are using a custom class inherited from java.lang.Object or some other classes that has not overridden toString() then you will get the address of the object instance rather than a descriptive string. In order to use iterator.next().toString() you need to make sure that you have overridden the public String toString() method properly. Alternatively you can do, YourObject yourObject = (YourObject) iterator.next(); String title = yourObject.methodThatGivesTheTitle(); Ashish Shrestha === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Hi Sumeet
You can load the default web browser on WinXX platform

rt.exec("rundll32 url.dll,FileProtocolHandler " + url);
The url must have the proper protocol of the url mentioned,
for example http://headlines.sourceforge.net
For a more complete example download headlines from

Hi! I believe you used the include directive to include a file. <%@ include ... %> includes the file and then compiles it into servlet.
