下面是测试的代码，先从文件中读取，让后存入数据库中，再从数据库中读出。 
public static void test() {

String DB_PASSWD = "root"; 
String DB = "MySQL"; 
String DB_DRIVER = "com.mysql.jdbc.Driver"; 

try { 
Class.forName("com.mysql.jdbc.Driver"); 
} catch (ClassNotFoundException e) { 
e.printStackTrace(); 
} 

String filePath = "file:C://expert//Expert.rdf-xml.owl"; 
IDBConnection con = JaneUtils.connectDB(DB_URL,DB_USER, DB_PASSWD, DB); 
System.out.println(con); 

JaneUtils.createDBModelFromFile(con, "expert",filePath); 
OntModel model = JaneUtils.getModelFromDB(con, "expert"); 
JaneUtils.SimpleReadOntology(model); 
} 

/* 简单读取本体中的各个class */ 
public static void SimpleReadOntology(OntModel model) { 
for (Iterator i = model.listClasses(); i.hasNext();) { 
OntClass c = (OntClass) i.next(); 
System.out.println(c.getLocalName()); 
}
