How can I pass Object to SQL server stored procedure using java code? -

public class student{  protected string name;  protected string marks;  public student(string name, string marks){   this.name=name;   this.marks=marks;  }   //getters , setters above } 

from other class tried below

student[] std=new student[2]; std[0]=new student("user1","80"); std[1]=new student("user2","70"); string section = "a";  connection conn=drivermanager.getconnection("jdbc:sqlserver://...."); callablestatement stmt= conn.preparecall("{call userdatils(?,?,?)}"); stmt.setstring(2, section); //stmt.setarray(3, std); stmt.setobject(3, std); stmt.registeroutparameter(1, java.sql,types.varchar); stmt.execute(); 

here issue below 2 lines.

    //stmt.setarray(3, std); stmt.setobject(3, std); 

when run above setobject saying, "the conversion unknown unknown unsupported.

i not able set value.

please me pass above student info stored procedure.
