[Mulgara-general] Help

[Bill OConnor]

hello,

I have been trying to get my head wrapped around mulgara and thought that I
would try a small experiment.

I downloaded dmoz constent.rdf.u8 and structure.rdf.u8 and wrote a groovy
script to load them into a model.

I then query the model but I never seem to get any results, probably because
I do not understand something
about how mulgara works. Here is the code:

import java.sql.*;

// Mulgara packages
import org.mulgara.itql.ItqlInterpreterBean;
import org.mulgara.query.Answer;

ItqlInterpreterBean  i = new ItqlInterpreterBean();

String query = "create <rmi://localhost/server2#content>;";
String answerString = i.executeQueryToString(query);

println answerString;


File f = new File("/home/wto/Projects/content.rdf.u8");
URI  u = new URI("rmi://localhost/server2#content");
long r = i.load(f, u);
query = """select \$s \$p \$o from <rmi://localhost/server2#content> where
\$s \$p \$o;""";
Answer answer = i.executeQuery(query);

answer.beforeFirst();

while(answer.next()){
println answer.getObject(0);
}

The results are:

<?xml version="1.0" encoding="UTF-8"?>
<answer xmlns="http://mulgara.org/tql#"><query><message>Successfully created
graph rmi://localhost/server3#content</message></query></answer>

Any help would be appreciated.
