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。。。
