Hiba, To update from OpenRDF Sesame to RDF4J please follow the instructions here: http://docs.rdf4j.org/migration/
It is mostly just renaming Java class imports: org.openrdf... to org.eclipse.rdf4j... A few of the classes are deprecated and should be switched to newer classes, such as ValueFactoryImpl being updated to SimpleValueFactory. There were are few more special cases as well, but let us know if you run into any of them. Hope that helps.
