Displaying Values in JSP Page using Struts

[Gopinath Reddy]

Hi all

I am new to struts I am getting problem while displaying the values in JSP page while using HashMap and ArrayList

/*This is the code for Array List*/

ArrayList al = new ArrayList();
while(rs.next()){
al.add(rs.getString(1));
}

I want to display the contents of al object in JSP Page using Stuts <logic:iterate> tag . Thing is this al object is having more that one value
so with out struts we can use for loops and Enumerations to display the value. But pls help me how to display this using struts logic:iterate tag.

Pls give me sample code.

/*This is my hash map code*/

HashMap hm = new HashMap();
while(rs.next()){
hm.put("name",rs.getString(1));
hm.put("age",rs.getString(2));
hm.put("sex",rs.getString(3));
}

The above is my HashMap code i have diplay this value in JSP using logic:iterate tag.


Pls Provide me code for this.

regards
Gopinath

One possibility..

First make sure you have the hashmap is in context (use a tag to put it into page context), or just put it in the session if it will be used over several pages..
Let's assume it's in page context, with the name 'contextHash':

<logic:iterate id="dbHash" name="contextHash" type="java.util.HashMap">
Name:<bean:write name="dbhash" property="name" />
Age:<bean:write name="dbhash" property="age" />
.
.
.
</logic:iterate>


Didn't test it.. hopefully it'll help you out.

There's an example of this in the docs.. here
