I don't have the latest html dtd but a peek into _form.dtd confirms that you
CAN use expression for the href attribute.
<tag>
<name>link</name>
<tagclass>org.apache.struts.taglib.form.LinkTag</tagclass>
<attribute>
<name>href</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
assuming same is true for _html.dtd, a possible work around is that you
construct the entire url expression first and then assign to the
<html:link>. something like,
<%
String url = "http://localhost:8080/internal/"+jsp;
%>
<html:link href=<%= url %> />
