jdbc - JdbcTemplate, MySQL error -

need help! have asked question here earlier - mysql/java error related 1 not identical (not sure of protocols @ such questions). working jdbc, mysql , encountering errors. first, code

public user find(string login) {   system.out.println("trying find user...." + login);       user user = this.jdbctemplate.queryforobject(         "select * xyz user_name = ?",         new object[]{login},         new rowmapper<user>() {             public user maprow(resultset rs, int rownum) throws sqlexception {                 user user = new user();                 user.setid(long.valueof(rs.getint(1)));                 user.setusername(rs.getstring(2));                 user.setpassword(rs.getstring(3));                 return user;             }         });   system.out.println("found user..." + user);    return user; }  public void create(user user) {      this.jdbctemplate.update("insert xyz (user_name,user_password) values (default, default, ?, ?)",             new object[] {user.getusername(),user.getpassword()}); 

i need give default values user_name, user_password (the 2 columns) don't know how , in "create(user user) block.

here's error code above:

severe: servlet.service() servlet appservlet threw exception java.sql.sqlexception: column count doesn't match value count @ row 1 

i have tried without 'default', 'default' , (?, ?) gives me yet error.

severe: servlet.service() servlet appservlet threw exception com.mysql.jdbc.exceptions.jdbc4.mysqlsyntaxerrorexception: have error in    sql syntax; check manual corresponds mysql server version     right syntax use near '?,?)' @ line 1 

your column list has 2 columns, , you're trying insert 4 values.

insert xyz (user_name,user_password) values (default, default, ?, ?) 

drop default values if column has default , not specified in column list.
