Tomcat buffer size problem?

[Willy Lin <Wi...@apexlearning.com>]

Hi:

	I have an application in a WAR file.  I have no problem with it
running under Tomcat 4.0.6.  However when I deployed it to Tomcat 4.1.21, I
got the following error:
	
org.apache.jasper.JasperException: /home/top_nav.jsp(0,0) Invalid buffer
size
	at
org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.
java:94)

org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
	at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
	
	
	I tracked the problem to the following line
	
<%@ page language="java" import="java.util.*,java.io.*,apex.vs_admin.*"
buffer="16k"%>

	The issue is the buffer.  When I take out the buffer setting, then
the page show up without any problem.  I tried my application under Tomcat
4.1.24 and it is having the same issue.
	
	Anyone encountered this?  TIA

In the copy of the spec I see:

<%@ page page_directive_attr_list %>
page_directive_attr_list ::= { language=” scriptingLanguage” }
{ extends=” className” }
{ import=” importList” }
{ session=”true|false” }
{ buffer=”none| sizekb” }
{ autoFlush=”true| false” }
{ isThreadSafe=”true|false” }
{ info=” info_text” }
{ errorPage=” error_url” }
{ isErrorPage=”true|false” }
{ contentType=”ctinfo” }

So I am *guessing* you need to change:
<%@ page language="java" import="java.util.*,java.io.*,apex.vs_admin.*" 
buffer="16k"%>
to
<%@ page language="java" import="java.util.*,java.io.*,apex.vs_admin.*"
  buffer="16kb"%>

I think its odd (probably a typo in the spec) because they use as an 
example in the spec (2.7.1): (notice is k, not kb)
<%@ page language=”java” import=”com.myco.*” buffer=”16k” %>
