resource defined in web.xml has null attributes but server.xml is ok
When I set up a db resource in web.xml and create it, for some reasons
it has null's in its attributes (such as username, url, driverClass,
..).
But when I set up the same resource in server.xml, it works fine.
>From the documentation it wasn't clear to me if both need to be set up
the same way. i.e. I use
<Resource name=X.../>
<ResourceParams name=X>
<parameter> ..... </parameter>
</ResourceParams>
in server.xml or web.xml, and then create a reference to it using
<Resource-ref> in web.xml.
Is this the correct way of doing this and if so any ideas on why a
resource defined in web.xml should have null attributes when i get the
object?
Thanks

Ok got it.
If I could read property I would have saved myself a lot of time. Just
to emphasise for anyone else looking at this thread..

The OR is important - i was defining a context for the same webapp in
server.xml *and* my context.xml. When I do this, the
META-INF/context.xml file does not get read and copied to
/conf/Catalina/<hostname>/<appname>.xml. Only the context in
server.xml is read.
Thanks for your help.

Re: resource defined in web.xml has null attributes but server.xml

Almost, you must define it in a context usually app specific rather than
DefaultContext. The bit that makes it almost is that a context (if not
DefaultContext) can be defined in the server.xml *or*
conf/<service>/<engine>/<app>.xml e.g. <catalina
home>/conf/Catalina/localhost/test.xml
If deploying as a WAR to Tomcat you would have
WEB-INF/web.xml *and*
META-INF/context.xml <--- app specific context definition

Re: resource defined in web.xml has null attributes but server.xml is ok
Posted by Nishant Deshpande <ni...@gmail.com>.
So - I cannot *not* define a resource at the server level (i.e. not
touch the server.xml or any other server configuration file) and only
define it in the app configuration files - i.e. web.xml ?
It seems like thats what you are saying below - just want to be sure I
understand clearly.
Thanks

Hi,
You need both. You define the resource in the context of the app and
then link to the resource from the app.

Tomcat in server mode question
Posted by Mufaddal Khumri <mu...@wmotion.com>.
Hi,
I am trying to run Tomcat 5.0.27 in server mode on a Win XP
Professional machine.
Tomcat is installed as a service on this box. I can start and stop it
and everything works fine. As soon as I specify the -server option
Tomcat wont start????
I do this by right clicking on the tomcat service icon and selecting
Configure --> Java: Java options and add the -server option there.
Am I doing this right or am i missing something?
Thanks.

RE: resource defined in web.xml has null attributes but server.xml is ok
Posted by Steve Kirk <to...@web-startup.co.uk>.
You don't say what version. I am aware that things are changing in this
area in 5.5.x so what I'm saying possibly applies to 5.0.x only. Check the
docs if you have a different version.
In 5.0.x, you have to put <resource-ref> in web.xml if you want to be
compliant with the servlet spec.
If you do that, you do not need the <Resource> anywhere. I don't think it's
allowed in web.xml anyway.
TC allows you to omit <resource-ref> and use <Resource> instead if you
really must, but this is not spec-compliant.
If you do use <Resource>, it goes wherever you put <ResourceParams> as
decribed below.
The ResourceParams can go under a number of places and this is where people
get confused. You can put it within:
<GlobalNamingResources> in server.xml, in which case you need a
<ResourceLink> under your <Context> to point from the <Context> to the
global resource
<Context> in server.xml, which you will have to create under the correct
<Host> (which is not recommended any longer)
<DefaultContext> in server.xml, again no longer recommended
CATALINA_HOME/conf/Engine/host/yourwebappname.xml - which contains purely
the <Context> tag
META-INF/context.xml within a war file (but not an open filesystem). If you
choose this option, you need to pay attention to TC reloading behaviour when
you edit the <Context>.
All this is in the docs. Well worth a read! :)
