still problem to load a property file in tomcat4.1.24???
Hi,
I have written a simple jsp page and in that i am trying to load a config
file for my application
Properties prop = new Properties();
try
{
InputStream fin =
ClassLoader.getSystemResourceAsStream("Shyam.config");
prop.load(fin);
System.out.println("File Loaded Successfully");
}
catch(Exception e)
{
e.printStackTrace();
}
}
But this is giving error as its not able to load Shyam.config file. which is
in WEB-INF/classes folder in my application.
Please show me a way.
Thanks
Pawan

Howdy,
RTFM:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html
Or search the archives.
WEB-INF/classes is automatically on the "classpath" for your webapp and
JSP. You don't need to modify the classpath environment variable nor
any of the classpaths in tomcat's startup scripts.

Posted by Jacob Kjome <ho...@visi.com>.
See:
http://marc.theaimsgroup.com/?l=tomcat-user&m=103904964313189&w=2
It will show you a number of different ways to do what you
require. Actually, pretty much all possible way to do what you require.
