http://api.neo4j.org/1.8.M06 - Look for class Node and methods family:
getRelationships().

You dont need to retrieve both nodes as you can get relationships from any
node (it's just a matter of relationship direction),
so basicly you do:

for( Relationship rel: node.getRelationships(Direction.OUTGOING,
YourRelationTypeHere) ) {  
    double w = (Double) rel.getProperty("weightage");
    if( w == 70 ) {
        w += 123.45;
       rel.setProperty("weightage", w)
    }

Hello

There are many ways to get a relationship from one of the related nodes:

http://api.neo4j.org/1.8.M06/org/neo4j/graphdb/Node.html#getSingleRel...

That will return a Relationship object, and from it, you can get the relationship property values:

http://api.neo4j.org/1.8.M06/org/neo4j/graphdb/Relationship.html
http://api.neo4j.org/1.8.M06/org/neo4j/graphdb/PropertyContainer.html...)

By the way, the Javadoc link for the 1.7.2/1.6.3 APIs is broken:
http://api.neo4j.org/1.7.2/
http://api.neo4j.org/1.6.3/

hello,            I have 2 nodes that are related to each other.This relationship has a property called weightage with a value' 70 '. I want to increase the value. To do so, I want to retrieve the value of the property (wightage=70)  between these two nodes.I can retrieve these two nodes.From the nodes, how can i get the relationship and then the property of that relationship?

Thanks in advance. :)
