I want to convert a character array into a Base64 stream using java.
The class
does a good job for this purpose. However, I need to provide parameters for the constructor. None of the following works for changing the line length
All of them return
No constructor 'org.apache.commons.codec.binary.Base64' with matching signature found.
Any ideas?

If you look at the list of methods available for that java class with
methodsview org.apache.commons.codec.binary.Base64
methods org.apache.commons.codec.binary.Base64 -full
you'll see that only the constructor with no input is listed and a fair number of methods are missing. The additional constructors and all those mising methods are all listed as having been introduced in version 1.4 of the library (look in the details of the documentation of each method).
Therefore, it's safe to assume that matlab ships with a version earlier than 1.4. You're out of luck with this one. I'm not sure you can safely replace the jvm that ships with matlab but you can always import a different library. I'm sure that there's more than one that does Base64 decoding.
Alternatively, if you're on windows you can use the convert class of .Net to do the same.
