| 12 | <para>The j2sdk package contains Sun's java development environment.
|
|---|
| 13 | This is useful for developing java programs and provides the runtime
|
|---|
| 14 | environment necessary to run java programs. It also includes a plug-in
|
|---|
| 15 | for browsers so that they can be java aware.</para>

| 18 | The JDK comes in two flavors, a precompiled binary and a source package. The
|
|---|
| 19 | precompiled binary is linked against gcc2 libraries. Due to the incompatibilities
|
|---|
| 20 | between gcc2 and gcc3, the precompiled java plugin causes problems when gcc3
|
|---|
| 21 | compiled packages (for example mozilla) try to load the java plugin.
|
|---|
| 22 | The source package requires registration at the Sun developer site and accepting
|
|---|
| 23 | the Sun Community Source License.
|
|---|
| 24 | The source code cannot be downloaded from some countries, so for users
|
|---|
| 25 | from those countries, the binary may be the only option.

| 28 | <para>Even if you plan on compiling the jdk source, you will need to download
|
|---|
| 29 | the binary version to bootstrap the jdk build.
|

| 30 | Follow the above link to download both source and binary packages. When
|
|---|
| 31 | downloading the source also download the mozilla headers package available at
|
|---|
| 32 | the same location.
