无法从套接字中读取更多数据
操作数据库的语句如下：

Java code

    public void insert(){        init();        String name = db.getName();        String password = db.getPassword();        String creator = db.getCreator();        String description = db.getDescription();                Connection conn = null;        PreparedStatement stmt = null;                try{            conn = dataSource.getConnection();            stmt = conn.prepareStatement("INSERT INTO DATABASES(DBNAME,DBPASSWORD,DBCREATOR,DBDESCRIPTION) VALUES(?,?,?,?)");            stmt.setString(1, name);            stmt.setString(2, password);            stmt.setString(3, creator);            stmt.setString(4, description);        }catch(SQLException e){            e.printStackTrace();        }        finally{            if(stmt != null){                try{                    stmt.close();                }catch(SQLException e){                    e.printStackTrace();                }            }            if(conn != null){                try{                    conn.close();                }catch(SQLException e){                    e.printStackTrace();                }            }        }            }

tomcat报错：

[解决办法]
可能是某个服务没启动，我以前也遇到过这样的问题。
