You have to add these dependencies:
{code:xml}
<dependency>
<groupId>org.ow2.frascati</groupId>
<artifactId>frascati-explorer-core</artifactId>
<version>1.4</version>
</dependency>

{code:title=extract|borderStyle=solid}
...
import org.objectweb.util.explorer.api.Tree;
import org.ow2.frascati.FraSCAti;
import org.ow2.frascati.explorer.api.FraSCAtiExplorer;
import org.ow2.frascati.util.FrascatiException;
...
System.setProperty(FraSCAti.FRASCATI_BOOTSTRAP_PROPERTY_NAME, "org.ow2.frascati.bootstrap.FraSCAtiFractal");

// Start FraSCAti and its Explorer.
FraSCAti frascati = FraSCAti.newFraSCAti();

Tree explorerTree = FraSCAtiExplorer.SINGLETON.get().getFraSCAtiExplorerService(Tree.class);

// Add the EasyVIPER core component.
explorerTree.addEntry("EasyVIPER", core.getComponent());
{code}

Beware of the {{FrascatiException}} you have to catch.

This will launch Frascati Explorer at runtime.
