i have been trying make maven-web application. calculating few stuffs , need display in graph trying display using neo4j. problem facing right able connect program neo4j not able directly open browser display graph.
my code :
public static void main( string[] args ) throws ioexception, { file filename=new file("c:/path/documents/neo4j/default.graphdb"); graphdatabasefactory dbfactory= new graphdatabasefactory(); graphdatabaseservice graphdb=dbfactory.newembeddeddatabase(filename); try(transaction tx=graphdb.begintx()){ node anode=graphdb.createnode(nodetype.tspot); anode.setproperty("pid", "a"); node bnode=graphdb.createnode(nodetype.tspot); bnode.setproperty("pid", "b"); relationship distance = anode.createrelationshipto(bnode,relationtype.distance); distance.setproperty("distance", 40); tx.success(); system.out.println("success"); } config nossl = config.build() .withencryptionlevel(config.encryptionlevel.none).toconfig(); driver driver = graphdatabase.driver( "bolt://localhost", authtokens.basic( "neo4j", "neo4j" ) , nossl); session session = driver.session(); session.run( "match (n) detach delete n" ); statementresult result = session.run( "match (n) return n" ); session.close(); driver.close(); graphdb.shutdown(); } the error getting :
