The "clearBuffer()" method didn't affect anything. The error page was still surrounded by all the other Tiles being rendered. I then tried "clear()" and it caused the following exception:
java.lang.IllegalStateException: response already committed at weblogic.servlet.jsp.JspWriterImpl.clear(JspWriterImpl.java:35) That's pretty much in-line with expectations according to documentation on "JSPInsider.com": clear() This method clears the ENTIRE content of the current buffer. If the buffer has been already been flushed then the clear operation throws an IOException error since the page's data has already been irrevocably written to the client response stream. Also when not using buffering calling this method will throw an IOException error. clearBuffer() Clears the current contents of the buffer. This function will not return an exception if the buffer has already been flushed. So I'm still stumped. The behavior I'm looking for may not be possible.

You might try buffering the output of your pages, so they aren't committed. But not sure that's the ideal solution. Another possibility is on the error.jsp, you can programmatically clear the output writer of any content it may have already buffered, then write out the stuff in your error.jsp you want to display. out.clearBuffer(); There might be other solutions though.

This is a continuation of a post I submitted yesterday as an "off topic" subject entiled: "[OT] web.xml <error-page> configuration problem" (Special thanks to David Graham for his many replies): Currently, this isn't showing up in the archives so I couldn't provide a link. However, I feel this is no longer an "off topic", but rather a Tiles/JSP topic. The issue I'm facing is how to forward to an error page (JSP) when a runtime exception (e.g. NullPointerException) occurs within my JSP Tile. Currently, I've added the following directive to each of my JSPs: <%@ page errorPage="/jsp/error.jsp" %> I'd prefer to only specify this information in one place, but I can't figure out how to do that either. The "<error-page>" setting in the web.xml doesn't appear to work for JSPs, just regular Java code inside the web container. Now, when an exception occurs in a Tile JSP, my error screen is displayed, but it's inserted into the page with all the other Tiles displayed as well. This can look really ugly depending on which Tile the exception occurs in. What I would I would prefer to do is automatically forward to a brand new screen. David Graham gave me the idea of redirecting to a Struts action: <%@ page errorPage="/displaySystemError.do" %> But this causes the following exception: java.lang.IllegalStateException: Cannot forward a response that is already committed I think that makes since b/c of the other Tiles (JSP Servlets) that have already been processed and committed HTML to the output writer. So I'm stumped at this point. Please reply if anyone has any bright ideas.
