Method Detail

findPathFromClasspath

public static java.lang.String findPathFromClasspath(java.lang.String suffix)

Finds a path to the specified suffix based on the classpath. This is done by getting the system classpath and breaking it into its pieces (each piece is separated by a semi-colon). For each piece, the suffix is appended onto the end and then each sub-path within it and checked. If a match is found, that path is returned. For example, if a classpath entry is C:/dir1/dir2/file.jar and the suffix is /subdir/file.exe, then the following paths would be checked in the specified order:

 C:/dir1/dir2/file.jar/subdir/file.exe
 C:/dir1/dir2/subdir/file.exe
 C:/dir1/subdir/file.exe
 C:/subdir/file.exe
 

Parameters:

suffix - the suffix to search for. For example, if you want to search for a path to a file, then you would simple pass in the filename (e.g. "file"). Optionally, you can pass in a sub-path as well (e.g. "/path/file").

Returns:

the path to the suffix or null if one couldn't be found.

getOperatingSystem

public static java.lang.String getOperatingSystem()

Gets the operating system.

Returns:

the operating system.
