我找到了一个晒太阳的程序员写的了不起的帖子，解决了我的问题！
public static void addDir(String s) throws IOException { try { // This enables the java.library.path to be modified at runtime // From a Sun engineer at http://forums.sun.com/thread.jspa?threadID=707176 Field field = ClassLoader.class.getDeclaredField("usr_paths"); field.setAccessible(true); String[] paths = (String[])field.get(null); for (int i = 0; i < paths.length; i++) { if (s.equals(paths[i])) { return; } } String[] tmp = new String[paths.length+1]; System.arraycopy(paths,0,tmp,0,paths.length); tmp[paths.length] = s; field.set(null,tmp); System.setProperty("java.library.path", System.getProperty("java.library.path") + File.pathSeparator + s); } catch (IllegalAccessException e) { throw new IOException("Failed to get permissions to set library path"); } catch (NoSuchFieldException e) { throw new IOException("Failed to get field handle to set library path"); }}然后我在使用JACOB方法之前添加了
addDir("C:" + File.separator + "java" + File.separator + "jre7" + File.separator + "lib")像魅力一样工作。
