Enquiry
Dear Sir or Madam,
I have some problems changing the host name of the Tomcat. The initial host
name for Tomcat is 'localhost', and I want to change to some other name.
Can it be done?
Thank you.
Regards,
Jesse Lee

You can't just assign host names. You can address tomcat as
http://localhost:8080/
or, if your host has another valid name, say frog.pond, then you can
address tomcat as
http://frog.pond:8080/
This is not a tomcat issue, it is an operating system issue, or really
a network issue. You can set your host name to whatever you like, but
if you are on a network then it is best to ask your sysadmin about it
- they can change your machine's entry in your DNS.

RE: Caching / Cloning
Posted by neal <ne...@yahoo.com>.
Siddarth,
Thanks but I'm thinking of two possible issues:
1. using the ServletContext.getContext() - won't this still just return a
pointer rather than cloning the cache? I looked at the API and didn't see
anything that said it was copying the object and creating a local copy.
2. Returning and having to handle the entire contents of the servlet context
could imply alot of overheard, I would think....at least presuming your
copying the context each time a page is called in ordert to obtain a local
copy of something, in this case an XsLT Transformer object.
Am I misunderstanding your suggestion, or how this would work?
Thanks.
Neal

Neal,
I have never worked with XSLT but I can show you the way where you can have
an
initial copy of ServletContext which you can use independently.
Interface ServletContext has a mathod called
getContext(java.lang.String uripath) returns ServletContext
You can use this method by giving uripath of same application to get a copy
of cache.
I hope, This suggestion may help you.

Reloading application with tomcat 4.x manager
Posted by Aviv Eliezer <ae...@aquanet.co.il>.
Hi guys,
When I'm using Tomcat Manager app to reload a webapp, I have a problem:
I use a ContextListener to do some application initialization and to put in
the ServletContext some objects.
When using reload, for some reason the servletContext I receive from the
destroy() event is different (?!?) from the ServletContext I received in the
init() event- thus I can't clean the resources the app used.
I never get these problems when I shutdown Tomcat- in which case I get the
same ServletContext from the init() and destroy() events. Is that a bug in
the Manager app?
Note that I don't have any other webapp installed, just one (so there's no
chance of confusing ServletContext of different webapps).
Anyone has an idea?

Caching / Cloning
Posted by neal <ne...@yahoo.com>.
Is there a way to make a copy of what's in my cache (getServletContext())
and make changes to that local copy, independent of whether the cached
object implements Cloneable()?
In order to speed up my XSLT I thought I would preload them (their
Transformer objects) into app scope and simply retrieve it as needed for
transforms.
This works fine except I just remembered that I need to set attributes on
these XsLT Transformer objects. Now, I am PRESUMING that this means that I
would then be locking up the servlet context each time I set one of these
parameters so then it seems I should clone() the object locally. That way I
could set the params locally without affecting (or locking) the cached
version). BUT Transfomer does not appear to implement the Cloneable()
interface.
Is there a way around this? Am I by any chance wrong about what's actually
happening here? Can anyone make a suggestion?
Here's what I'm doing basically:
ServletContext application = getServletContext();
application.setAttribute("TEMPLATES_HASH",templates);
(where templates is a Hashtable containing Transformer objects)
Thanks.
