public List getRecordList(){

String sql="select * from record";
ResultSet rs=st.executeQuery(sql);
	      while(rs.next()){

I am getting exception:
java.lang.ClassCastException: java.lang.String cannot be cast to [Ljava.lang.Object;

on these line:

for (Object[] Details : detail) 

please advice.
Thanks.

It means the list is not holding what you expect... you are expecting the list to contain Object array instances. And it returned a String object.

No, you would appear to be trying to cast a String to some sort of array, which you cannot do.

[Campbell Ritchie]

If you have a result set, it might be obtaining a String when you expect an array. Can you actually get arrays out of result sets?

[Babu Singh]

resultset returns the rows which all is string.

So, why are you treating the strings as object arrays?
