The constructor BASE64Encoder() is not accessible due to restriction on required library
2010-01-27 09:27

在Eclipse中编写Java代码时,用到了BASE64Decoder,import sun.misc.BASE64Decoder;可是Eclipse提示:
Access restriction : The type BASE64Decoder is not accessible due to restriction on required library C:\Program
files\java\jre6\lib\rt.jar
Access restriction : The constructor BASE64Decoder() is not accessible due to restriction on required library C:\Program files\java\jre6\lib\rt.jar

搞不懂是为什么,最后在http://forums.dzone.com/eclipse/384-access-restriction-problems.html找到答案,只需要在project build path中先移除JRE System Library,再添加库JRE System Library,重新编译后就一切正常了。但是我仍然很疑惑是为什么。。。
