ClosenessCentrality in graphalgo

[Salim Afra]

Hi,

I was trying to calculate closeness centrality using graphalgo package. Unfortunately, I am getting "NullPointer" exception. (Also, I am using code from here exactly same http://grepcode.com/file/repo1.maven.org/maven2/org.neo4j/neo4j-graph-algo/2.1.7/org/neo4j/graphalgo/centrality/ClosenessCentralityTest.java?av=f) I have 4 nodes in my network and 2 by 2 connected each other (see Figure). I am thinking the problem singleshortespath function. But i could not find more example.

How can I solve the problem?

thanks
