Java: Loading data from a file located under project folder fails
Tag : java , By : TBG

like below fixes the issue You need to get the path right.
getClass().getResourceAsStream("...") loads a file relative to the path the current class is located in (because you use the class to query the resource). Thus, if your class is located in a package named com.example.mypackage and you give a string "config.yaml", that file is searched relative to the class' package folder.
getClass().getClassLoader().getResourceAsStream("config.yaml");

Why does not process a $.getJSON function if file located not in project folder?


Tag : jquery , By : Shrek Qian

I think the issue was by ths following , Due to the Same-Origin Policy, you cannot use AJAX to read a file from a different domain.
The whole point of $.getJSON() is that it uses JSONP to bypass this restriction.

How to read a file that is located in the project folder java

To fix this issue Looking at the error it doesn't look like you are getting the full path. Instead of
p.concat("/HackGSU/bad_words.txt");
p = p.concat("/HackGSU/bad_words.txt");
