[suresh sai]

Hi friends.
I need one requirement.I have to display the list using the display tag.With a single list its working fine.But my list of objects, inturn each object consists another list.I have to display the last list.
Ex:- ClassRoom is my class.
ClassRoom contains studentList that contains Student as object.
Each Student Object contains subjectsMarksList.
Now I have to display subjectsMarksList as follows.
sub1 sub2 sub3
---- ---- -----
50 20 30
20 40 40
---- ---- -----
Total
This is for all students I have to do.I have to represents only subjects and marks.

Could you please help me how can I do that?
Thanks in advance.

Friends.,
I found out one solution that is almost similar to what I need,using in combination with <logic:iterate>.But the headers are printing two times.

Here I am showing the snap shot of the code.
<logic:iterate id="student" name="classForm" property="studentList">
<display:table name="student.subjectsMarksList">
<display:column property="sub1" />
................................
</display:table>
</logic:iterate>
It is printing all the values but header is repeating as follows.

sub1 sub2 sub3
---- ---- -----
50 20 30
---- ---- -----
sub1 sub2 sub3
---- ---- ----
20 40 40
---- ---- -----
Please help me to solve it.
Thanks in advance.
