JavaEE - WAR - Deployed :: How to read a file from resource directory

Question

I believe the "correct" way one is supposed to do this is `getResourceAsStream()` but it just doesn't seem to cut it. My situation: I have a web application in Java that will be eventually deployed to a few different web servers the possibilities are GlassFish, Tomcat, and WildFly. Currently I'm working on a mac with Netbeans and I have access to WildFly and GlassFish. The project is mavenized What I need to do is read and write two different Excel files. One serves as a "template" and one serves as the output file. The application previously ran standalone and I'm trying to wrap it into a JSF web site. I need to obtain an `FileInputStream` for my one of the methods and eventually create an output file which will be served back to the user via http. From what I gather the appropriate way to do this is supposed to be: XLSX File ``` /src/main/resources/ANALYSIS_template.xlsx ``` Location once compiled into WAR file :: WildFly ``` /usr/local/opt/wildfly-as/libexec/standalone/deployments/…

Accepted Answer

In the end it looks like this is the code that did the trick. I have NO idea why but apparently it worked and I'm not complaining.

```
InputStream inputStream = getClass().getClassLoader()
                         .getResourceAsStream("/ANALYSIS_template.xlsx");
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
```

I made a new project form scratch and this code worked. Thanks for the help guys!
