That is not correct. JSP's require app server like Tomcat or JBoss to run.

Tomcat is a 'simple' servlet container, not even a full blown web server. JBoss is
a full blown application server, one of the first programs that conformed to Sun's
specification. JSPs run perfectly well in a servlet container so the previous poster
was perfectly correct.

No they were not. First off Tomcat is not a web server. It is an application server.

It is very true that Tomcat only supports the Java Servelet portion of the J2EE API, but there is no requirement that full J2EE support be required to be an app server. Just that it be able to run applications which Tomcat is very capible of doing.

Read carefully: the very first sentences from Tomcat's home page:
Apache Tomcat is the servlet container that is used in the official Reference Implementation for the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process.
There is much more to application servers than just the http protocol and servlets.

Thank you for proving my point. Tomcat is NOT a web server. It compiles and executes application code making it an application server.
There is much more to application servers than just the http protocol and servlets.
I think this is the hair that is being split here. There can can be a lot more to an app server, but there does not have to be. It just has to compile, exicute and serve applicaitons.
There is no requirement that the entire J2EE stack to be implemented to call a server an app server. If we followed that logic then web applications could only be written in Java. I am sure more than a few ASP and C# guys would disagree with that.

For the historic currency information we need a graph Java applet:

One thing i'm finding very quickly as my servlets become more logically

performance from one servlet rather than 12 servlets performing the logical...

Hi
i'm having a little problem of understanding some differences between
Java and PHP.
Well, PHP runs on the server. so, if my script saves some data from a
database to 'c:\temp', it saves the data to the local disc of the
server itself. correct? but java runs on the client-side. this means
the my applet trying to save data from a database to 'c:\temp' saves
the data to the local disc of the client... am i right?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
