Your alternatives are to use a scriptlet or to use the Struts-EL library in the
nightly build (as described in another response to this). With Struts-EL, a
direct translation of your code would look something like the following (with
some renaming):
<logic:iterate id="country" name="countryCollection">
<logic:equal name="country" property="value" value="${user.country}">
<bean:write name="country" property="label" />
</logic:equal>
</logic:iterate>
