sysLoader.getResource() problem in java

I am having following lines of code.

sysLoader = (URLClassLoader)Thread.currentThread().getContextClassLoader();
url = sysLoader.getResource("tempFile.txt");

It is giving an weird problem. If I run this from a path where there is no space in the path (Folder names) then it is running fine. But if the path contains any spaces (line "c:\New Foler...") then it is not working.

How to solve this?

EDIT: In more detail - I inspected the sysloader object.

sysloader -> UCP -> path

Is having a path with character %20 instead of space

And therefore all the URLs are null.

How to resolve this?

Solution

  • This is known by Sun/Oracle, their advice is to use URI objects which will remove the %20 characters:

    Instead of doing this:

    FileInputStream fis = new FileInputStream(url.getFile());

    you can force any %-escaped characters to be decoded by first converting the URL to a URI, and then use the path component of the URI as the filename:

    URI uri = new URI(url.toString());
FileInputStream fis = new FileInputStream(uri.getPath());
