I asked a similar question yesterday.
see:
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg39132.html
I ended up wrapping the Hashmap
Test class:
--------------
public class HashWrapper implements java.io.Serializable {
java.util.HashMap map = new java.util.HashMap();
public HashWrapper() {
map.put("item1", "H");
map.put("item2", "E");
map.put("item3", "I");
}
public String getItem(String item){
return (String)map.get(item);
}
}
----------------
request setAttribute("hashWrapper",new HashWrapper());
------------------
Then I used the syntax for the tags:
<logic:equal name="hashWrapper" property="item(item2)" value="H"></logic:equal>
item(item2) will become getItem("item1")....
This should work the same for the jsp getProperty tags, though have not
tried it.
Hope this helps.

Subject: RE: Want to Access Key/Value Pairs in Hashtable within jsp
I see in the struts examples where LabelValueBeans are placed in a Vector
or
List and used with select option tags.
So what I would define in my form bean is a collection of LabelValueBeans
that looks like this:
("label1","value1")
("label2","value2")
("label3","value3")
I will have a getLabelValueCollection() method that would return the
collection of these LabelValueBeans
then in my jsp I want to do a bean write or getProperty passing in the
label
and getting back the value. Something like this:
<jsp:getProperty name="responseBean"
property="labelValueCollection("label3")"/>
I do not understand the jsp syntax to pass in the label and get the value
out of the collection.

If your using Struts 1.1-b2 check out org.apache.struts.util.LabelValueBean

Hashtable might be convenient for you but JSP tag libs (especially in
Struts) are very bean-centric.

You could represent the Hashtable as a bean with this API:
dynclass.sourceforge.net

<jsp:getProperty/> is the "built-in" way, although the Struts
<bean:write> and <bean:define> tags are preferred.
