sun.misc.BASE64Encoder找不到jar包的解决方法？ 在MyEclipse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\l
base64找不到下面连个jar包也可以解决
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
报错:
Access restriction: The type JPEGImageEncoder is not accessible due to restriction on required library C:\Java\jre1.6.0_07\lib\rt.jar
此时解决办法：
Eclipse默认把这些受访问
