I’ve recently been doing some work with code that is still running in a Java5 environment, to make matters worse, no new libraries can be added to the application. With these restrictions, I’ve had to resort to using only functions available in the standard installed JVM. The code relies on HTTP Basic authentication, and thus needs to use Base64 encoding.
The following classes were to be used…
Unfortunately, Eclipse did not like this and gave an error…
Access restriction: The type BASE64Decoder is not accessible due to restriction on required library C:\jdk1.5.0_22\jre\lib\rt.jar
Thankfully, this class (while not recommended, is in every build of the JVM that I have seen), you can tell Eclipse to only ‘Warning’ on it’s usage…
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 needed.
BTW, I would normally rely on the
commons-codec.jar for this functionality, and use
org.apache.commons.codec.binary.Base64 for this purpose.
