Array required, but java.sql.Array found

I am getting the Error at
"out.println("The object present is " + arrobj[1]);"

where ---------------------    
         Object[] obj;
        Object[] obj_sat3;

      obj_sat3 = ar2.toArray();
      obj = ar.toArray();

      Array arrobj = (Array)session.getAttribute("obj1");
        out.println("The object present is " + arrobj[1]);

but when i just use the obj object rather than session name "obj1" it works fine....
out.println("The object present is " + obj[1]);

Environment:-- JSP

can you print?
out.println("The object present is " + arrobj.getClass());
out.println("The object present is " + arrobj);
out.println("The object present is " + arrobj.length);

Hi Gurvinder,

I tried all the Print statements...

--first two throws nothing...empty string though i used simple text like..
 out.println("The object present is " + arrobj.getClass());
 out.println("The object present is " + arrobj);
 "I guess there is some problem with " 
Array arrobj = (Array)session.getAttribute("obj1");

--Third print statement
Error-- Variable length at
out.println("The object present is " + arrobj.length);

>Array arrobj = (Array)session.getAttribute("obj1");
You set obj1 with  
and you declared  
Object[] obj;  
Please try  using  
Object[] arrobj = (Object[])session.getAttribute("obj1");

rather than type casting to Array type cast it to the same object which you have used in setting the attribute 'Object[]'
