<bean:write name="xxx" property="logname"/>
<bean:write name="xxx" property="password"/>
<bean:write name="xxx" property="phone"/>
<bean:write name="xxx" property=""id/>
</logic:iterate>

Not 100% certain, but I believe you can use the <bean:define> for that.

Then you can access the values as a page variable using, for example <%=idValue%> in your code, like in a request string:
yourAction.do?id=<%=idValue%>
or something along those lines.

Hi skyspeed, glad I could help.
When you use the <bean:define>, the bean defined by the tag has to be an object. Primitives like an int are wrapped with the appropriate wrapper class behind the scenes by the Struts framework.
In your case, the framework assumes you have a method called getId() in class xxx(if you don't the tag will throw a JspException). Since the method returns an int property, the tag will define a bean of type Integer wrapping the retrieved value.
<bean:define id="dd" name="xxx" property="id" />
So behind the scenes, Struts has created a page-scope bean of type Integer identified as "dd", so to get the actual wrapped int you would use:
<% int i=dd.intValue();%>
I believe that should work for you. Post again if you have any other questions or problems.
Cheers,
E
