Tomcat / Spring MVC / Tiles 2.2.2 InsertAttributeTag Jasper Exception Being Thrown
In an attempt to migrate a Spring/Tiles 2.2.2 EE Application from was 7 to apache-tomcat-6.0.35 I am seeing exceptions in my presentation layer, pertaining to jasper and the rendering of my tiles.
Here is an exception...
Code:
SEVERE: Servlet.service() for servlet spring-controller threw exception
org.apache.jasper.JasperException: /WEB-INF/jsp/tilestest/parent.jsp(16,3) The TLD for the class org.apache.tiles.jsp.taglib.InsertAttributeTag specifies an invalid body-content (JSP) for a SimpleTag.

at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:148)
at org.apache.jasper.compiler.Validator$ValidateVisitor.visit(Validator.java:791)
In an attempt to better understand the issue, I've simplified an example in my codebase, and I will present the code/wiring here.

private static final String TILESTEST = "tilestest/home";
@RequestMapping(value = TILESTEST, method = RequestMethod.GET)
public String home(ModelMap model) {
return TILESTEST;
}
}

/app is the context root of my app
If I hit http://localhost:8080/app/tilestest/home I hit my TilesTestController home method successfully, but then fail with the exception above during processing of the <tiles:insertAttribute name="body" /> within parent.jsp
If I remove <tiles:insertAttribute name="body" /> the parent.jsp renders successfully.
There seems to be an issue/conflct with Jasper/Tiles/Tomcat? I have tried debugging the doTag() method of InsertAttribute but my breakpoint never gets hit.
All of this works on was 7.0
Any thoughts/ideas would be greatly beneficial and very much appreciated.
Thanks!
