Frustrating Tiles error - Error - tag.getAsString

I can't seem to see the problem here.  I think it's simple but I've just been staring too long!  I keep getting a 'Error -tag.getAsString' error in my app.  I suspect it has nothing to do with the tiles defs but is happening before that.  But I can't figure it out.  Below is my info and the error message.  If anyone can help me out, I'd appreciate it! 
 
Thanks in advance, 
Mike

RE: Frustrating Tiles error - Error - tag.getAsString

Posted by "David G. Friedman" <hu...@ix.netcom.com>.
Michael,

Where is line 95?  Your index.jsp looks too short to have 95 lines. Is it
one of the included files?  Can you cut & paste all tiles:getAsString lines
from the related tiles for main.layout? Those would be
/jsp/header.jsp
/jsp/login.jsp
/jsp/footer.jsp
/jsp/welcome.jsp

Also, are you positive there are no errors in your container's startup log
files that would indicated problems loading Struts or tiles?  Please include
those logs showing proper startup.  If Tomcat, that would be stderr.txt,
stdlog.txt and localhost_log.2004-11-13.txt. :)

Regards,
David

Sorry about that.  So many files, I forgot to list the
plugin element in the struts-config file.  Here it is:

 <plug-in

  <set-property property="definitions-config"

If anyone has any ideas as to my problem, please let

RE: Frustrating Tiles error - Error - tag.getAsString

Posted by "David G. Friedman" <hu...@ix.netcom.com>.
Michael,

Can you show the Tiles plugIn from your struts-config.xml?  You don't
mention it.  It is probably something like this:

<plug-in className="org.apache.struts.tiles.TilesPlugin">
	<set-property property="moduleAware" value="true"/>
	<set-property property="definitions-parser-validate" value="true"/>
	<set-property property="definitions-config"
  		value="/WEB-INF/tiles-defs.xml"/>
</plug-in>

Regards,
David
