Wierd File Acess Error.

Hi guys,
In my code, I have this line:


And this line looks for a specific file called "replacer.properties" under:

C:\Documents%20and%20Settings\ray\workspace\
.metadata\.plugins\org.eclipse.wst.server.core\tmp0\
wtpwebapps\project1\WEB-INF\classes\replacer.properties

This file is present under the location and is accessible when I click folder by folder and finally reach the "classes" folder, but when I copy the whole path to the browser and try to open it, it gives me a "unable to find file" error.

Likewise, my code throws a FileNotFound Exception, any ideas on why although the link exists, I cant access it when I try to copy the whole link?

I think the %20 occurrences are the problem.

In URLs, spaces are replaced by %20. In file systems however, they are not.

You could try replacing every occurrence of %20 by a space, but that might break your code when run on a web server.


However, why use a FileInputStream? Besides "getResource(String name)" which returns a URL object, both ClassLoader and Class also have "getResourceAsStream(String name)" which returns an InputStream object. You can use this instead of your FileInputStream.

Hi.

You can try to find the file with a local look up (based on the package structure) using getClass().getResource(filename).

You can put replacer.properties along your classpath and your JVM should pick it up based on the relative reference to the filename alone. If you need to use an absolute path, try java.net.URLDecoder to resolve your %20s.
