you have a tiles definition defined in your xml that extends a master tile that contains less attributes than what you provided in your master definition. basically, your master tile jsp has a tiles:insert tag that doesn't have a value provided for as specified by the attribute(either in the tiles-def.xml or in the specific tiles jsp). make sure a value is provided for each tiles:insert that you defined.

Thanks Alan...

To use a tiles definition, we need to create a definition in tiles-defs.xml and can start using the definition in any jsp with <put> tag right?

If i am wrong will you tell me how to do it?

I had exactly the same error. After hours, I found a trick to do before searching paths diplayed above.
Clean the Work dir of tomcat, simple, isn't it ! Looks like this incredibly stupid thing keeps some data even after full server start. it could simply prevent you from having a good display even after correcting the tiles issues.

<put name="body" value="" />
<put name="footer" value="folder for jsp /aaa.jspfooter.jsp" />
</definition>


<definition name="as u want to put in struts_config.xml" extends="xxx">
<put name="body" value="/folder for jsp /homepage.jsp" />
