A goal that's almost enshrined in the Java fundamental commandments, as Sun took out an advertising campaign to back it up

One of the most fundamental design principles of Java is captured in its motto "Write Once, Run Anywhere." It describes how a .class file encodes its instructions at the bytecode level, allowing portability between different machines that, through a specific virtual machine implementation, resolve the bytecodes into executable instructions to give the program life. It's a goal that's almost enshrined in the Java fundamental commandments, as Sun took out a high-profile advertising campaign to back up the "100% Pure Java" slogan and engaged Microsoft in battle for their proprietary language extensions.

Another fundamental design principle of Java is that functionality cannot be removed, so a program compiled to run on one version of a Java Runtime Environment (JRE) is able to run on future versions without re-compilation. The idea behind this is that as users upgrade their machine's JRE, they can be confident that none of their Java software will stop working because an API it relied on was removed.
This is the story of a
Mac application developer
(okay - it's about two of
them) who set out on a
quest to find an
application development
tool based on Java so his
boss would let him

There was only one catch

SOA is mostly associated
with technologies such as
BPEL, SCA and Web

really imply these
technologies? In this

Any large Java source
base can have insidious
and subtle bugs. Every
experienced Java
programmer knows that
finding and fixing these
bugs can be difficult and
costly. Fortunately,
there are a large number

One of the things I
really enjoy at the
moment is the recognition

programming as a fully
