Hi experts,
I'm trying to build my first small application and getting errors. Its
my first programming-project since 3 years and now I have to learn
neo4j, spring and maven :-)
I'm using Neo4J Server and want to access via REST. This works fine -
i tested it with the jersey-api-client. I think that there is a
problem with my pom.xml.
I would be so thankful for help. I'm spending now 2 days on that
problem. Thank you in advance!
You find my error-message and the end of the discussion.
This is my Class with main-function:
public class App
{
public static void main( String[] args )
{
System.out.println( "Hello World!" );
final FileSystemXmlApplicationContext ctx = new
FileSystemXmlApplicationContext("src/config/applicationContext.xml");
}
}
This is the applicationContext.xml:
