在Eclipse中使用jena将本体存入书库，就是用论坛中大家分享的代码
import java.io.*;
import java.sql.SQLException;
import com.hp.hpl.jena.db.*;
import com.hp.hpl.jena.rdf.model.*;
public class Ontology{
public static final String strDriver ="com.mysql.jdbc.Driver"; // path of driver class
public static final String strURL ="jdbc:mysql://localhost/ontology"; // URL of database
public static final String strUser ="root"; // database user id
public static final String strPassWord ="mysql"; // database password
public static final String strDB="MySQL"; // database type
public static void main(String[] args){
try{// 创建一个数据库连接
IDBConnection conn = new DBConnection ( strURL, strUser, strPassWord, strDB );
// 加载数据库驱动类，需要处理异常
try{
Class.forName(strDriver);
}catch(ClassNotFoundException e) {
System.out.println("ClassNotFoundException, Driver is not available...");
}
// 使用数据库连接参数创建一个模型制造器
ModelMaker maker = ModelFactory.createModelRDBMaker(conn);
// 创建一个默认模型，命名为 MyOntology
Model defModel = maker.createModel("MyOntology");
// 准备需要存入数据库的本体文件，建立输入文件流
FileInputStream inputStreamfile = null;
try {
File file = new File("C:\\Expert.rdf-xml.owl");
inputStreamfile = new FileInputStream(file);
} catch (FileNotFoundException e) {
e.printStackTrace();
System.out.println("Ontology File is not available...");
}
InputStreamReader in = null;
try {
in = new InputStreamReader(inputStreamfile, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
// 读取文件
defModel.read(in,null);
// 关闭输入流读取器
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
// 执行数据转换，将本体数据存入数据库
defModel.commit();
// 关闭数据库连接
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}catch(RDFRDBException e){
e.printStackTrace(System.out);
System.out.println("Exceptions occur...");
}
}
}
运行后出现这样的错误
Usage:
java jena.schemagen [options ...]
Commonly used options include:
-i <input> the source document as a file or URL.
-n <name> the name of the created Java class.
-a <uri> the namespace URI of the source document.
-o <file> the file to write the generated class into.
-o <dir> the directory in which the generated Java class is created.
By default, output goes to stdout.
-e <encoding> the encoding of the input document (N3, RDF/XML, etc).
-c <config> a filename or URL for an RDF document containing
configuration parameters.
Many other options are available. See the schemagen HOWTO in the
Jena documentation for full details.
是什么意思啊 怎么解决啊
请大家帮忙啊 谢谢啦！
