The number of folks using persistent state Net.Data functions is very small
since this an IBM HTTP server V4R3 only feature. There were a couple of
folks who have used it and posted to IBM's net.data forum on their website.

One rather negative point of persistent state CGI (which is what Net.Data
uses) is that it requires browsers capable of supporting HTTP 1.1 which
means Netscape 4.x and MS IE 4.x due to the additional HTTP header
requirements to communicate with the server.

Look carefully at the query_string built by Net.Data and attached when you
output your page. You might want to display the environment variables in
your macro when you process the response from the server check to be sure
that the handles are the same.

I was wondering if anyone has any experience with the usage of DTW_ACCEPT
function calls within macros. I have the @dtw_static() defined as the first
line of my macro. I define my handle = "". I do the @dtw_rtvhandle(handle)
and the @dtw_accept(handle) but when I run my macro I get an error at the
accept line that tells me:
NET.DATA Error: Line 46, Data cannot be sent until a DTW_ACCEPT or
DTW_TERMINATE function has
been called.

Anyone familiar with this error or any ideas on how to debug the error?

Follow the links on our front page at http://ignite400.org to "Bob's
Book" (which is finally being edited for publication by IBM's publishing
company). It will take you to a number of working net.data samples which
include the source code and working examples ranging from basic variable
handling to a fairly complex html form example with database inserts and

Where can I get my hands on some good examples of net.data code so i don't
have to reinvent the wheel

I use Net.Data for about 98% of my web sites. The other 2% is actually
calls to RPG programs. Net.Data is easy to learn, can incorporate html
generated by any tool (like frontpage), and gets the job done fast.

JAVA Servlets would be great if you can figure out how to develop and deploy
them. At IGNITe/400 we put up the Cybotics search engine which is Java
Servlet based and it runs great. Developing servlets to run under WebSphere
is a completely different issue. You need a great deal of JAVA expertise,
must understand and be able to write Java Beans, and then you must
understand servlets and finally you have to figure out how to configure and
administer Websphere. There are millions of words on the Internet
describing all of this, but none that I have found that will put the whole
thing together

I've read several IBM manuals and redbooks, heck, I've even taken the MndQ
tutorial that comes with VA for Java and read a horrid book (given away by
IBM) written by two clowns in Toronto from some idiotic company called HSA.
These folks wrote a JAVA class library (which IBM did not enclose with the
book) and claim that using their classes are the only way to write JAVA

If anyone can write a JAVA book that a) teaches you have to use the JAVA
language, b) provides you meaningful sample code (not calculus to calculate
parts of circle or a useless todo list), c) explains Java Beans, d) explains
servlets, and finally e) explains how to deploy Servlets on the AS/400 using
WebSphere, then A) I'd buy it, and B) I'd get very serious about WebSphere
and Servlets.

IBM is falling all over its sword in the JAVA arena! So much meaningless
marketing drivel gets pushed into every piece of printed or Internet writing
that they publish, you can't understand what they are saying.

Oooops, I'm afraid I got on my soap box. Your quite correct that JAVA
servlets are a good way to go. Unfortunately, I don't see a way to get
there! Beware of IBM professional services folks claiming to be WebSphere
or Java Servlet experts! They haven't built any either and you will be
triaining these folks at your expense.

How to develop a website using the AS/400 database?

Schluter R.J.

Our site runs on the I/NET Commerce Server, and we are examining ways to
incorporate data from our AS/400 with our website. As I see it, we have two
kinds of applications where data on te AS/400 is used:

1. In static HTML pages which contain a small amount of information from the

To make changes to the HTML page possible by another departement I would
like to be able to use a tool like FrontPage. At the moment I think Server
Side Includes are the best solution to put the dynamic data in the pages.

2. Complete applications, where the complete pages are created from

I have created a small demo application that uses COBOL CGI programs, and
has the HTML stored inside a message file, so I can keep text outside the
program, and combine it easily with the data.
Other options I'm currently looking at are Net.Data or some 4gl tools like
COOL:Plex or Lansa for the Web, but what about Java servlets?

Anyone with other ideas for tools to use, suggestions about techniques, or
experiences with these kinds of development?

Thanks in advance.
