In Tiles, you can put attributes only into layout pages. In short terms
you should modify your tiles-defs.xml this way:
<definition name="header.with.title" path="/header.jsp">
<put name="pageTitle" value="Welcome" />
</definition>
<definition name="base.definition" path="/layout.jsp">
<put name="leftNav" value="/leftNav.jsp" />
<put name="footer" value="/footer.jsp" />
</definition>
<definition name="page.home" extends="base.definition">
<put name="header" value="header.with.title" />
<put name="body" value="/home.jsp" />
</definition>
