Reading a file in tomcathome/conf folder
I wish to keep configuration property file outside my war. Suppose i keep it
tomcathome/conf/myfile.properties
How can I read it using classloader from my webapp application code. I am
not able to access it.
I tried using this.getClass().getClassLoader() or even
this.getClass().getClassLoader().getParent() but coudnt !

Heh. We always ride people for using the filesystem and here Konstantin
goes suggesting that someone use it :)
Cid, the short answer is that catalina.base isn't available via any
default ClassLoader. If you wanted to, you could place the file into
Tomcat's lib directory, but that has it's disadvantages, too.

Why? Just use:
new FileInputStream(new File(System.getProperty("catalina.base"),
"conf/yourfile.properties"));

Rather than trying to look up the config file path on the classpath
you could simply
ask the administrator to supply it in a context parameter override.
That way the administrator decides where it should go, not you and you
can supply
an internal default if you wish.
If you're using Spring this is very easily accomplished with their
ServletContextPropertyPlaceholderConfigurer
class
hope this helps
