Re: reading the xml file
Doing it the way you describe will only work from a servlet. If that is
ok, stop reading and do it that way. :-)
A more general way would be to use a classloader instead. There are many
good articles on how to do this (google for 'classloader resource'), but
one simple way is this:
InputStream is =
getClass().getClassLoader().
getResourceAsStream("foo.xml");
To do this, the resource foo.xml *must* be on your classpath. If it is
in a package, you need to specify that in the call made to the
getResourceAsStream() method. Also this cannot be done in a static
context. If you are in a static block of code, you can use this instead:
InputStream is =
Thread.currentThread().getContextClassLoader().
getResourceAsStream("foo.xml");

Hallo,
I thinkin how I can read the xml file from /WEB-INF directory.
I found something as
InputStream is =
servletContext.getResourceAsStream("/WEB-INF/something.xml")
but how I can get servletContext?. Or, is t good way to read data, as
datasource names, from xml file and store it as instance of config file
in
session? is there any better way?
Thanks for help,
Jiri

From inside an Action, you can call getServlet().getServletContext().

It had *better* be a good way to read data, because Struts uses this
technique itself to read your struts-config.xml file :-).
A common technique is to read configuration information from a resource
like this at the startup time of your web application (in Struts, you
could use a PlugIn for this and put the reading code in the init()
method). After reading, you would typically store the resulting data
into servlet context attributes (also known as application scope) so
that they are available to all users. Indeed, this is exactly what
Struts does -- for example, the ModuleConfig for the default application
module is stored under servlet context attribute key
"org.apache.struts.action.Module" (normally referenced by the symbolic
constant Globals.MODULE_KEY) so that all parts of Struts have access to it.
Thanks for help,
