Sometime it's just hard not to say anything. There are lots of different options for making this work and you don't have to change to JSTL to do it. The logic:iterate tag is absolutely fine, you just have to get the right parameter names.
Thanksfully there is a pattern to how the parameters of the logic:iterate tag work, and it's brilliant news that they conform to the other Struts tag libraries. The absolutely fantastic news is that there is documentation at: http://struts.apache.org/struts-doc-1.2.7/userGuide/struts-logic.html#iterate Your code should look like: <logic:present name="rows" scope="session"> <logic:iterate name="rows" scope="session" id="row"> Hi </logic:iterate> </logic:present> You'll notice how the same parameter names are used on the logic:present as the logic:iterate, means you only have to learn how to use a parameter once and can then assume it is used the same way on the other tags.
