Subject RE: properties files
Date Tue, 25 Feb 2003 14:25:21 GMT
	thank you for the attention, im developing a bean to interact with the
properties file.

	I believe that  ServletContext is only available to servlets,

but perhaps the filename can be a parameter in the constructor :D

	the reason why im using a properties file is to make the configuration
transparent and easy, to my clients...

so i they change the mysql db parameters they can easily edit the properties
file without much knowledge.

also another advantage i saw in that was the ability to load and save
directly to a file.

if there is a better way im all ears :)

You need to put your property files in WEB-INF/classes or in a jar in
WEB-INF/lib

Then you can use the getResourceAsStream(..) method of the ServletContext of
your webapp :


properties.load(getServletContext().getResourceAsStream(filePath))
