java调用MYSQL存储过程问题

[libing821109]

public Collection select_procedure(String proce_name){

ArrayList<String[]> list=new ArrayList<String[]>();
Connection conn=null;
CallableStatement msProcedure=null;
ResultSet rs=null;
try{

conn=getConnection();
msProcedure=conn.prepareCall("{call "+proce_name+"}");
msProcedure.registerOutParameter(1,java.sql.Types.VARCHAR);
rs=msProcedure.executeQuery();
在msProcedure=conn.prepareCall("call"+proce_name)这句报错，错误是java.sql.SQLException: Callable statments not supported.
请给予帮助

解决了,mysql驱动版本不对

但是executeQuery()那句报错:java.lang.NullPointerException
在数据库执行存储过程可以查到数据,
