Throws:

IOException

Method Detail

loadLibFromJar

public static void loadLibFromJar(String fileName)
                           throws IOException

Loads library from current JAR archive The file from JAR is copied into system temporary directory and then loaded. The temporary file is deleted after exiting. Method uses String as filename because the pathname is "abstract", not system-dependent.

Parameters:

filename - The filename inside JAR as absolute path (beginning with '/'), e.g. /package/File.ext

Throws:

IOException - If temporary file creation or read/write operation fails

IllegalArgumentException - If source file (param path) does not exist

IllegalArgumentException - If the path is not absolute or if the filename is shorter than three characters (restriction of File.createTempFile(java.lang.String, java.lang.String)).
