mutual exclusion on a page
Hello -
I am writing a database application where I want to
restrict update access to a particular table to one
user at a time. What I want to do is implement some
sort of 'lock' that would be, in java servlets terms,
saved on the ServletContext level. I am thinking that
I will write an action which checks and sets this
'lock' (probably just a boolean variable) to control
the pipeline which delivers the page containing update
capabilities.
Here's the question: where/how in cocoon do I save a
'global setting', ie equivalent level to java
ServletContext? And/or is there a better way to
achieve mutual exclusion on the delivery of a
particular page than what I've described?
I'd be glad to read documentation on this subject if
someone could please point it out to me. All of your
suggestions are appreciated. Thanks.
Sylvia

xsp generating xml
Posted by Abhishek Goel <Ab...@morganstanley.com>.
hi,
i am generating my xml through xsp.
xml generated is like this(it's an examle of that tpe as original xml is
very large)
<?xml version="1.0" encoding="UTF-8" ?>
- <message xmlns:xsp="http://apache.org/xsp">
<name>Hello</name>
</message>
when i am passing this to sitemap i am getting the error
"org.xml.sax.SAXParseException: The markup in the document preceding the
root element must be well-formed."
this is because of the "-" sign before <message> element.because as soon
as i remove that manually it works fine.
my xsp is
<?xml version="1.0"?>
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp" >
<message>
<name>Hello in !</name></message>
</xsp:page>
could any one suggest me how to get rid of this error.
Thanks and regards
Abhishek
