Not without installing the java dev kit or what ever the pkg was called.
However it did not integrate in the UI nor is it current. It's very
outdated and I am not aware of another.

However if you are familiar with Linux, then get a Java SDK with
runtime, I prefer Sun's but I have heard IBM's to be faster on Linux.
Then get a recent copy of Tomcat or another Java app server and install
it.

You will need to compile a module for Apache and configure Apache to
forward requests to Tomcat.

I need to make a little how to one of theses days. I may have posted
some basic instructions a while back. Check the archives.

ChiliSoft ASP does run on and uses and underlying jre, but not one I
would recommend using with Tomcat. Nor do I think ChiliASP wants you to
use it's jre?

All over the place, but Sun's tutorials are a good place to start.

I love Java. I played around with ASP for a while, but I turned away
from it for the some of the same reasons as PHP. Granted most of ASP had
to do with MS, PHP had to more to do what I could not do to it.

For example in java I create libraries of shared core functions. I then
can wrap web apps via JSP and Servlets around them. I can also wrap a
GUI to be used client side.

Portable to almost any OS, allot of devices, and etc.

So I can spend less time duplicating the same functionality. Not to
mention less to debug, modify, or improve.

For me it's Java everything. However I am working with and will use C++
in conjunction with Java. I would never touch C++ if it weren't for the
speed differences.

Now with respect to web apps, Java may be preferred to C++. I will
elaborate more in a bit.

You may be able to reduce some things but sharing code and etc. Now one
of my reasons for loving Java so much is it's caching ability. It can
definitely speed things up, but if not implemented properly can slow
things down as well. Now Java is not a language you will be able to
learn in a night. Not unless you are a genius, or have been programing
for years. It's not C or C++, but possible the closest thing on the
learning scale.

I would highly encourage you and anyone else to look into Java. It's
well worth it. I have been very pleased with it. Not to mention what all
you can do right off the bat. Allot of libraries, and functionality all
there ready for you to use.

I started out on a RaQ4r with ChiliSoft ASP, and then migrated to Java.
Now I am using an XTR still running Tomcat, and pretty much all I do is
Java.

Outside of the one link I provided above, in my opinion the best Java
resource out there. Sun is responsible for it. The only thing you won't
find there is install how-to's on Tomcat and integrating it with Apache.
For that the web, others, and I can help you out.

Or if you do not want to mess around with it you can always pay me to
install and get things going for you. Although it's not to difficult if
you try and do not give up.

Good luck, and let me know how it goes.
