<title>Introduction to j2sdk</title>

<para>The <application>J2SDK</application> package contains Sun's
<application>Java</application> development environment. This is useful for 
developing <application>Java</application> programs and provides the runtime
environment necessary to run <application>Java</application> programs.  It also 
includes a plug-in for browsers so that they can be <application>Java
</application> aware.</para>

<para>
The <acronym>JDK</acronym> comes in two flavors, a precompiled binary and a 
source package. The precompiled binary is linked against <acronym>GCC
</acronym>-2 libraries. Due to the incompatibilities between
<acronym>GCC</acronym>-2 and <acronym>GCC</acronym>-3, the precompiled java 
plugin causes problems when <acronym>GCC</acronym>-3 compiled packages (for 
example <application>Mozilla</application>) try to load the <application>Java
</application> plugin. The source package requires registration at the Sun 
developer site and accepting the Sun Community Source License.
The source code cannot be downloaded from some countries, so for users
from those countries, the binary may be the only option.</para>

<para>Even if you plan on compiling the <acronym>JDK</acronym> source, you will 
need to download the binary version to bootstrap the <acronym>JDK</acronym> 
build. Follow the below link to download both source and binary packages. When
downloading the source also download the <application>Mozilla</application> 
headers package available at the same location.</para>

<para>For users who cannot download the <application>J2SDK</application> source owing to license restrictions, <application>blackdown
</application> has an <acronym>GCC</acronym>-3 based precompiled version.
