我想在数据库中插入一个日期,但它不会出现任何出现的错误消息.当我在Oracle DB中查看我的表时,我找不到我插入的数据.

java.util.Date daterecep;
// getter and setter
public void setdaterecep( java.util.Date daterecep) {
         this.daterecep=daterecep;
} 
public  java.util.Date getdaterecep() {
       return  daterecep;
}

和

    nt val=0;
    try {
        val = st.executeUpdate("insert into tabdate (date) values('"+daterecep+"')" );
    } catch (SQLException ex) {
         Logger.getLogger(Insertdate.class.getName()).log(Level.SEVERE, null, ex);
    }

    System.out.println(val);
    return resultat;
}

我使用了PreparedStatement,但它没有用,我只是尝试执行Java代码

val = st.executeUpdate("insert into tabdate(date) values('12/12/2004')");

并添加

public static void main (String args[]) throws SQLException {

    Insertdate B= new Insertdate();
    B.connexionBD();
    B.insert();//function for the insertion
}

它的工作原理.

以下是我的代码我的bean

        return this.cond;
    }

        this.cond= cond;
        }

    String value = req.getParameter("cond");
        try {
