+
+<p>
+In order to test the validity and intregity of the JustJ JRE p2 repositories,
+a <code><a href="https://git.eclipse.org/c/justj/justj.tools.git/tree/products/org.eclipse.justj.tools.sample.product/Sample.product">Sample.project</a></code> is defined to use them.
+The <code><a href="https://ci.eclipse.org/justj/job/build-sample-product/">build-sample-product</a></code> pipeline builds them and publishes them to
+<code><a href="https://download.eclipse.org/justj/www/download.eclipse.org.php?file=sample-products">https://download.eclipse.org/justj/sample-products/*</a></code>.
+Currently the Windows and Linux versions work.
+For Mac there seems to be a packaging problem with the build, i.e., the application won't launch from the icon, but it does run from the command line:
+<pre>
+$ Eclipse-Sample.app/Contents/MacOS/eclipse
+</pre>
+This suggests that the JREs themselves are working well.
+We hope to figure out the packaging problem for Mac so that all these samples are fully functional.
