errorPage
Defines a URL to a resource to which any Java programming language 
Throwable
 object(s) thrown but not caught by the page 
implementation are forwarded to for error processing.
The provided URL spec is as in Section 2.5.2.
The resource named has to be a JSP page in this version of the 
specification.
If the URL names another JSP page then, when invoked that JSP 
page's 
exception
 implicit script variable shall contain a reference 
to the originating uncaught 
Throwable
.
The default URL is implementation dependent.
Note the 
Throwable
 object is transferred by the throwing page 
implementation to the error page implementation by saving the object 
reference on the common 
ServletRequest
 object using the 
setAttribute()
 method, with a name of
javax.servlet.jsp.jspException
 .
Note: if 
autoFlush=true
 then if the contents of the initial 
JspWriter
 has been flushed to the 
ServletResponse
 output 
stream then any subsequent attempt to dispatch an uncaught exception 
from the offending page to an 
errorPage
 may fail.
contentType
Defines the character encoding for the JSP page and for the response 
of the JSP page and the MIME type for the response of the JSP page.
Values are either of the form  TYPE  or  TYPE; charset=CHARSET  
with an optional white space after the  ; . CHARSET, if present, must 
be the IANA value for a character encoding. TYPE is a MIME type, 
see the IANA registry for useful values.
The default value for TYPE is  text/html ; the default value for the 
character encoding is ISO 8859 1.
See Section 2.7.4 for complete details on character encodings.
2.7.2
Synchronization Issues
JSP Pages inherit the Servlet semantics as described in the Servlet 2.2 specification.  In this 
section we briefly summarize the threading and distribution issues from that specification, as 
they apply to JSP pages.
