Visualize-JS - Authorization Error while rendering the Jasper Report

[akshaykalway]

Occasionally getting "Unauthorized Error" when my Base64 encoded token contains a "+" sign (which is a valid Base 64 character)

I am using Visualize-JS to render the Jasper report in MVC Boilerplate. To authenticate every request, I am using the pre authorization flow where I am sending a Base64 encoded token from my application and on Jasper server decoding it.

Everything is working fine except, occasionally I am getting "Unauthorized Error". When I checked I found it is only failing when my Base64 encoded token contains a "+" sign (which is a valid Base 64 character). My C# code is URL encoding the + sign as %2B whereas the Java code while decoding the same URL converts %2B into a space. (Note - I am encoding in C# and decoding in Java since, Jasper server only supports JAR files).

Is anyone else facing this or have faced earlier and found the solution?

For now, as a work around I am replacing the space with a + sign but, I am searching for a better solution.

What Java expression are you using to decode?
