    <p>Trying to connect to Neo4j from java I get the following error:</p> <blockquote> <p>Exception in thread "main" java.lang.RuntimeException: Error starting org.neo4j.kernel.EmbeddedGraphDatabase, /data/graph.db at org.neo4j.kernel.InternalAbstractGraphDatabase.run(InternalAbstractGraphDatabase.java:323) at org.neo4j.kernel.EmbeddedGraphDatabase.(EmbeddedGraphDatabase.java:100) at org.neo4j.graphdb.factory.GraphDatabaseFactory$1.newDatabase(GraphDatabaseFactory.java:92) at org.neo4j.graphdb.factory.GraphDatabaseBuilder.newGraphDatabase(GraphDatabaseBuilder.java:197) at org.neo4j.graphdb.factory.GraphDatabaseFactory.newEmbeddedDatabase(GraphDatabaseFactory.java:69) at ..... </p> <p>Caused by: org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.transaction.XaDataSourceManager@4514ba77' was successfully initialized, but failed to start.

The same jar files and java code works good though in a windows machine. The web admin interface works well (hence path to db may not be a issue since I ve given the same path in org.neo4j.server.database.location and org.neo4j.server.webadmin.data.uri), </p> <p>The java code I used to connect is :</p> <pre><code>String dbpath = "/NEO4J_HOME/data/graph.db/"; graphdb = new GraphDatabaseFactory().newEmbeddedDatabase(dbpath); </code></pre> <p>Can you tell what might cause the <strong>java.lang.IllegalArgumentException: No schema index provider org.neo4j.kernel.api.index.SchemaIndexProvider found</strong> </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
