import sun.misc.BASE64Encoder results in error compiled in Eclipse

Question

For this two imports;

import sun.misc.BASE64Encoder; import sun.misc.BASE64Decoder; 

I got this error:

Access restriction: The type BASE64Decoder is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar 

How can I resolve this error?

Answer 1

Go to Window-->Preferences-->Java-->Compiler-->Error/Warnings.
Select Deprecated and Restricted API. Change it to warning.
Change forbidden and Discouraged Reference and change it to warning. (or as your need.)

Answer 2

That error is caused by your Eclipse configuration. You can reduce it to a warning. Better still, use a Base64 encoder that isn't part of a non-public API. Apache Commons has one, or when you're already on Java 1.8, then use java.util.Base64.
