Steve,

This is how I used a HashMap in a jsp:

<logic:iterate id="item" name="user_list" property="userList" >

<TR>
<TD><bean:write name="item" property="key"/></TD>
<TD><bean:write name="item" property="value"/></TD>
</TR>

</logic:iterate>

getUserList() method in my user_list bean returns a HashMap.

Hope this helps.

-Nimmi

 Hi Jon. I'm having a similar problem as Dudley with a HashMap. I tried
playing around with your example but couldn't get it to work within the
context of what I'm doing. Perhaps another example would help. For
example, I have a scriptlet that looks something like:

 fee.fie.fo.sql.ResultSetBean rsb =
        (fee.fie.fo.sql.ResultSetBean) request.getAttribute("resultBean");
 java.util.HashMap hm = rsb.getProperties();
 String foobar = (String) hm.get("foobar");
 out.println("foobar = " + foobar);


So, the ResultSetBean contains a HashMap as a property. I get a reference
to the HashMap and then can extract a value with a key as input. Any ideas
on the syntax of doing this with "bean" tags? TIA.
