<td width="70%" valign="top" align="left"> <p>In 3.1, the core Eclipse plug-ins,
including SWT, are packaged as single JAR files rather than as a directory of files.
The SWT plug-in JAR now contains everything including the native libraries.</p>
<p>In order to run a standalone SWT application, the native libraries must be placed
on the java library path. If you use the SWT Binary and Source download this is resolved for you
but sometimes it is useful to build against the SWT plug-in from the Eclipe SDK.
In Eclipse 3.0, standalone SWT developers added the native libraries using -Djava.library.path.
In Eclipse 3.1, since the native libraries are inside a JAR, developers cannot
easily locate the libraries.</p>
<p>To run and debug your SWT application using the SWT plug-in from
Eclipse, you can use the SWT application launcher to locate the native libraries. A shortcut to the
launcher is available in the context menu of your Java class via
<b>Run As &gt; SWT Application</b>.</p>
