import problem

Hi All
   I use nb-lookup-inspector and found out my lookup classes are:

--Classes in lookup--
class org.netbeans.modules.cnd.loaders.OrphanedElfObject               org.netbeans.modules.cnd.loaders.OrphanedElfObject@555e0034[/Users/peter/NetBeansProjects/PeterI/interrupt/interrupt0/interrupt0.o@f3914b19:20c1a978]
class org.netbeans.modules.masterfs.filebasedfs.fileobjects.FileObj    /Users/peter/NetBeansProjects/PeterI/interrupt/interrupt0/interrupt0.o@f3914b19:20c1a978
class org.openide.nodes.FilterNode                                     org.openide.nodes.FilterNode[name=null][Name=interrupt0, displayName=interrupt0.o]
class org.openide.windows.DelegateActionMap                            org.openide.windows.DelegateActionMap@690a3899 for org.netbeans.modules.project.ui.ProjectTab[Files,0,0,391x1272,invalid,layout=java.awt.BorderLayout,alignmentX=0.0,alignmentY=0.0,border=,flags=256,maximumSize=,minimumSize=,preferredSize=]


But when i do:

Lookup context = Utilities.actionsGlobalContext();
FileObj file = context.lookup(FileObj.class);


I got no way to import org.netbeans.modules.masterfs.filebasedfs.fileobjects.FileObj, how to add the library to make the import possible?

thanks
