You have the sense and structure of the loops correct; I believe that
you're just referring to properties with the wrong names. Without a
BeanInfo class, the method "getMy_StringA()" turns into the property
"my_StringA", not "My_StringA". (Note the initial lowercase character.)
It's more typical in Java not to include the "_", but this doesn't change
the way that JavaBean accessors are interpreted by the Introspector.
Thus, if you try the following instead, it should work:
<table>
<c:forEach var="test1" items="${X}">
<tr>
<td><c:out value="${test1.my_StringA}"/></td>
</tr>
<c:forEach var="test2" items="${test1[my_List]}">
<tr>
<td><c:out value="${test2.my_StringB}"/></td>
</tr>
</c:forEach>
</c:forEach>
</table>
