I have found the solution. Eclipse does offer direct access to the package explorer in org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart , but it is discouraged.

import org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart;

...

PackageExplorerPart part= PackageExplorerPart.getFromActivePerspective();
IResource resource =  /*any IResource to be selected in the explorer*/;

part.selectAndReveal(resource);

This will highlight whatever IResource resource is and expand the tree as necessary.
