I am sorry , I have got the solution.
I should write it so:
Properties info=new Properties();
Statement st = dbconn.createStatement();
String str_sql="SELECT * FROM customer where cname='"+t1+"'";
ResultSet rs = st.executeQuery(str_sql);
then all Chinese query critery is in order.
but the make error still harass me. if anyone can help me?
