So I have a program, whereby I create all the nodes and add relationships
from and to them. When creating these nodes they are stored in
nodes_created, for me to then use in relationship creation.
for(Map.Entry<String[], Integer> entry:
company_counts_backward.entrySet()){
String[] node_names = entry.getKey();
String company_from = node_names[0];
String company_to = node_names[1];
int count = entry.getValue();
Node companyFromNode = nodes_created.get(company_from);
Node companyToNode = nodes_created.get(company_to);
Relationship relationship =
companyFromNode.createRelationshipTo(companyToNode, Relations.WORKED_AT);
relationship.setProperty("relationship-type", "knows");
relationship.setProperty("length", count);
}
However at the line: `Relationship relationship =
companyFromNode.createRelationshipTo(companyToNode, Relations.WORKED_AT);`
I am getting an exception: `Exception in thread "main"
org.neo4j.graphdb.NotInTransactionException`
Anyone know what causes this and what I am doing incorrectly?
