How to use PageRank algorithm in JUNG?

Question

I am using JUNG as my tool to visualize network graph and compute network attributes(ex: indegree, outdegree, and pagerank).

I know JUNG already implemented PageRank algorithm, but there were no instruction on using pagerank algorithm in the manual(http://jung.sourceforge.net/doc/index.html).

Does anyone knows how to do it?

I also tried the following code, but it came out an error "Vertex CLP Holdings Ltd not an element of this graph".

public void calcPageRank()
{
   PageRank<MyNode, MyLink> alg = new PageRank<MyNode, MyLink>(g,0.1);
   alg.initialize();
   System.out.println(alg.getVertexScore(new MyNode(53084,"CLP Holdings Ltd")));    
}

code file is here

THX!!
