Why do java.awt libraries require X Server?
This issue applies to the
Java Barcode Package
and the Java based encoders provided with 2D font packages such as the
Data Matrix,
PDF417,
Aztec,
QR-Code and
Maxicode.
The Abstract Window Types libraries (AWT) are there to provide basic
Windows-Type graphical facilities for Java programmers to send graphics
to an end user. The Unix version of these libraries is specifically
created to use the X Server to render these graphics. So, to answer
the question in its simplest form: The java.awt libraries are actually
wrapper classes to produce graphics based on the X Server operating
environment. This means to produce graphics, such as GIF and JPEG files,
the awt libraries from an X Server environment must be present, unless
the "headless mode" environment is properly setup.
