No I'm trying to generate them dynamically. So in the action I'd do
the following:
Map<String,String> params = new HashMap<String,String>();
...
params.put(somename, "somevalue");
Then use that map in the JSP to set the parameters. These parameters
are not set on the current page so including them with includeParams
won't help me.

Wim

Try this then:
<s:url id="testUrl" action="test">
<s:iterator value="parameters">
<s:param name="%{#key}" value="#value" />
</s:iterator>
</s:url>
or
<s:url id="testUrl" action="test">
<s:iterator var="param" value="parameters">
<s:param name="%{#param.key}" value="#param.value" />
</s:iterator>
</s:url>
