sun.misc.base64decoder.jar是Windows系統中常用到的重要jar架包,如果你的電腦里少了這個文件,就會造成很多的不便,不過你可以用小編提供的文件來解決問題啦!
【常見問題】
sun.misc.BASE64Encoder找不到jar包的解決方法?
1.右鍵項目-》屬性-》Java bulid path-》jre System Library-》access rules-》resolution選擇accessible,下面填上** 點擊確定即可?。。?br />
2.在MyEclipse中編寫Java代碼時,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
解決方案1(推薦):
只需要在project build path中先移除JRE System Library,再添加庫JRE System Library,重新編譯后就一切正常了。
解決方案2:
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings ->
Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning
