jwiki's Issues

Null Pointer Exception

Hello,
I used your program and I liked it very much, it is very helpful and easy to extend and use.
When I was using your application I faced a problem, when you pass a parameter to constructor to search in Wikipedia and there is no information about that topic program will throw a null pointer exception. I just tried to solve it by adding an "if" condition before creating the "JSONObject" for retrieving the image and check if the "displayTitle" is not null then try to create the "JSONObject" and retrieve the image otherwise just give them a value like "information not found".
Now if I pass a parameter that it doesn't have any return value your code will not return a null pointer exception.
I just wanted to let you know, please check this issue and if what I did isn't correct or if it will cause a confliction in other parts, let me know.
Thank you

Can You Add this project to Maven?

Hi @viralveghela I love this project and its really useful to me. But it will be if you add it to maven . then users can access it using maven without downloading them directly. Also can you Javadoc this so that there is a documentation.
