According to the document of Neo4j, I tried below to create the database using Neo4j Java APIs in Eclipse:

GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabase("D:/Eclipse/Workplace/test");

and also tried to set the path under the Neo4j folder("D:\Neo4j3.0.1\workplace3"). But I got the same error:

The method newEmbeddedDatabase(File) in the type GraphDatabaseFactory is not applicable for the arguments (String)

Then I tried to import java.io.File; and add:

File dbpath = new File("D:/Neo4j3.0.1/workplace3");
org.neo4j.graphdb.GraphDatabaseService db = dbFactory.newEmbeddedDatabase(dbpath);

then the previous two packages are not used: org.neo4j.graphdb.GraphDatabaseService;, org.neo4j.graphdb.Transaction; But I can compile the program and show "Done successfully" in the Eclipse console.

When I tried to connect to the database using neo4j-ce.exe, it gave me below Alert:

Starting Neo4j failed: Component org.neo4j.server.database.LifecycleManagingDatabase@397b7f" was successfully initialized, but failed to start. Please see attached cause exception.

My code:

package com.peterlan522.neo4j.java.example;

import java.io.File;

import org.neo4j.graphdb.GraphDatabaseService;
import org.neo4j.graphdb.Transaction;
import org.neo4j.graphdb.factory.GraphDatabaseFactory;
import org.neo4j.graphdb.Node;
import org.neo4j.graphdb.Relationship;

import org.neo4j.graphdb.Label;
import org.neo4j.graphdb.RelationshipType;

public class Neo4jJavaAPIDBOperation {

public enum Tutorials implements Label { JAVA, SCALA, SQL, NEO4J,}
public enum TutorialRelationships implements RelationshipType { JVM_LANGIAGES, NON_JVM_LANGIAGES,}

public static void main(String[] args) {

    org.neo4j.graphdb.factory.GraphDatabaseFactory dbFactory = new GraphDatabaseFactory();
    File dbpath = new File("D:/Neo4j3.0.1/workplace3");

    //GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabase("D:/Eclipse/Workplace/test");

    org.neo4j.graphdb.GraphDatabaseService db = dbFactory.newEmbeddedDatabase(dbpath);

    try (org.neo4j.graphdb.Transaction tx = db.beginTx()) {

        Node javaNode = db.createNode(Tutorials.JAVA);
        javaNode.setProperty("TutorialID", "JAVA001");
        javaNode.setProperty("Title", "Learn Java");
        javaNode.setProperty("NoOfChapters", "25");
        javaNode.setProperty("Status", "Completed");                

        Node scalaNode = db.createNode(Tutorials.SCALA);
        scalaNode.setProperty("TutorialID", "SCALA001");
        scalaNode.setProperty("Title", "Learn Scala");
        scalaNode.setProperty("NoOfChapters", "20");
        scalaNode.setProperty("Status", "Completed");

        Relationship relationship = javaNode.createRelationshipTo
        (scalaNode,TutorialRelationships.JVM_LANGIAGES);
        relationship.setProperty("Id","1234");
        relationship.setProperty("OOPS","YES");
        relationship.setProperty("FP","YES");
        tx.success();
        }
        System.out.print("Done successfully");
        }
}

Could anyone help on this? And give executable examples on this. Thank you so much!

Below are the softwares version: Neo4j community version 3.0.1, Eclipse Mars(4.5.0), Java 1.8.0_91, JRE System Library: JavaSE-1.8

  • In your log there should be a stack trace at the point of failure. You need to edit your post and copy/paste the stack trace into it so we can see what is actually causing the failure. Commented Jul 11, 2016 at 16:04
  • Try it with different workspace instead of "workplace3". It worked for me. Commented Nov 11, 2016 at 10:57
