During the last month my colleagues and I were immersing into the world of
modern JavaScript frameworks. We didn’t start from scratch though. My
business partners spent the first 5 years of this century porting
PowerBuilder, a used-to-be-popular client server tool, to a JavaScript
framework. That product was called XMLSP and you can still find its 5-year
old version online. The word AJAX was not even invented back then. In 2006, a
killer UI framework Adobe Flex 2 was released and we started using it. It was
clearly better than any AJAX offering, and I was not shy in publishing blogs
and articles explaining its superiority to any AJAX solution available at the
time.
Flex remains a great solution for developing UI for the enterprise Web
applications, and our company,Farata Systems, is committed to support any
client who decides to hire us for any Flex/AIR Web/Desktop... (more)
This article is a transcript from a recorded conversation I had with Anatole
Tartakovsky and Victor Rasputnis – my business partners at Farata Systems.
This conversation took place on the mountain after the day of skiing.
Yakov. There are many ways of creating Web applications and creating them for
the enterprises is not the same as developing a Web site for a pizzeria in
your neighborhood. During the last five years we’ve been using mainly Adobe
Flex for development of the front end of Web applications. Flex applications
work in a well known and predictable run-time environment c... (more)
JDJ's Enterprise Editor, Yakov Fain (pictured) writes: If you are planning to
hit the job market, you may need to refresh some of the Java basic terms
and techniques to prepare yourself for a technical interview. Let me offer
you some of the core Java questions that you might expect during the
interviews.
For most questions I’ve provided only short answers to encourage
further research. I have included only questions for mid (*) and senior
level (**) Java developers. These sample questions could also become handy
for people who need to interview Java developers (see also ... (more)
To read local file streams, a program has to specify the file's location,
i.e. "c:\practice\training.html". The same procedure is valid for reading of
the remote files: just open the stream over the network. Java has a class URL
that will help you to connect to a remote computer on the Internet.
At first, create an instance of the class URL:
try{ URL xyz = new URL("http://www.xyz.com:80/training.html"); }
catch(MalformedURLException e){ e.printStackTrace(); }
The MalformedURLException could be thrown if a non-valid URL has been used,
for example missed protocol if you forgot to sta... (more)
Java Basics: Introduction to Java Threads, Part 2
A program can perform its actions either in a sequence (one after another) or
in parallel. In a sequential mode, if a program needs to call two methods of
a class, the second method is called after the first one completes. In other
words, such programs have only one thread of execution. In some cases, when a
second method does not depend on the results of the first one, you can
substantially speed up the processing by executing these methods at the same
time in a multi-threaded mode.
A good example of a program that creates multipl... (more)
