Results in the same as
<s:set name="a" value="'/jsp/'#parameters.file" />
which means that a remains unset.
Same for:
<s:set name="a" value="/jsp/%{#parameters.file}" />
<s:set name="a" value="'/jsp/'%{#parameters.file}" />
<s:set name="a" value="%{/jsp/#parameters.file}" />
<s:set name="a" value="%{'/jsp/'#parameters.file}" />
Best,
