Iterator

[sudhir pavan]

I have problem in displaying two list values in jsp using struts.

I have two list values

list 1

no name
1 ss
2 dd

list 2

no product name
1 mine ss
2 temp ss
3 disk dd

using iterator i need to display the elements in the below format

name ss
count 2

1 mine
2 temp

name dd
count 1

1 disk

Even I had the same problem.
Just have a look at the thread : How can I call the Action class inside <logic:iterator> tag in struts 1.3

If you write a code as follows:

<logic:iterate id="l1" name="myActionForm" property="List1">  
//In this line I want to fire an action which will load List1 object from the database for each 'name' passing 'name' as request parameter.  
         <logic:iterate id="l2" name="myActionForm" property="List2">  
                           //Some lines of code here.  
         </logic:iterate>  
</logic:iterate>  

If an action could be fired in line 2 then it performs the business logic and retrieves each 'product' from List2 object with 'name' passed as request parameter.

But this is not possible with struts1(As I was informed in the forum).

The other way is to use an array of List. Sort of 2D array. List2 in your case.

The first row will contain two List2 objects(i.e [1,mine,ss] and [2,temp,ss]).
The second row will contain one List2 object(i.e [3,disk,dd]) and so on.

Try this and tell me if it works.
Also visit my thread and comment on it as somebody has tried his best to help me.

Looks like the data structure being used has a problem.
I would actually prefer to have something like below

Category List (ss/dd)
|
|->(each category has a) Product List (mine/temp/disk)

Anybody to oppose?
Also see if the database has integrity constraint for these two tables. If yes, there should be a definite problem!!


Anyways,
