array passing dynamically

[jazz2k8]

Hi

Can anyone help me how to set and get an array attribute values??

Eg:

for(int i=0;i<array.length;i++)
{
session.setattribute(array[i],array[i]);
}

now i would like to get this array value in forwarded jsp???

thanks

OK create a class with name Constants,create in it the array which will be public and will have all the names for session attributes.

package ourbeans;
public class Constants { 

   public static final String[] array = {"username","password"}; 
   

   ...

after that in jsp file you create the session variables:

<jsp:useBean   id="constants"  class="ourbeans.Constants"    />

for(int i=0;i<constants.array.length;i++)
{
      session.setattribute(array[i],array[i]);
}

In this way you can get attributes from the session:

session.getAttribute(cosntants.array[0]);

[Norm]

session.getAttribute(cosntants.array[0]);

A better coding style is to use constants to get at fixed position elements in an array. When you add a new element between two existing ones, there will be a simple coding change in one place, vs looking through your code to change all the hard coded indexes.

   ...
final int NameIdx = 0;  // index to name
 ...
session.getAttribute(cosntants.array[NameIdx]);
