Tomcat 9 specify config folder path

Question

I am running in Tomcat 9 an app that needs to read several .config files but I get an java.io.IOException.

These .config files are located in WebContent folder.

How can I tell Tomcat to read this path? Can be related to IntelliJ settings for the project?

This is how is loaded the config file:

 ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

InputStream is = classLoader.getResourceAsStream(this.configFile);

Value of this.configFile is: cnp-filter.config

You need to get them from CLASSPATH and not from filesystem. Look on https://stackoverflow.com/questions/20451386/java-jar-cant-find-file — Michal, Sep 21 '20 at 11:05
could you please show us the code used to read those resources? Further, could you also show the exact stacktrace produced by the error? ClassLoader.getResourceAsStream() does not actually throw IOException as of JDK 9 JavaDoc. — Michal, Sep 21 '20 at 12:13
Sure I am adding it. The strange thing is that the code was working before on a WebSphere server. — Stefano Maglione, Sep 21 '20 at 12:17
Could you please add the StackTrace of the error? Further the value of `this.configFile` would be of interest. — Michal, Sep 21 '20 at 12:24
If the value is preceded by `/`, i.e. `/cnp-filter.config` does it still not work? — Michal, Sep 21 '20 at 13:03
src/main/resources or use ServletContext to read them - see my answer. — Michal, Sep 21 '20 at 13:17

Try using this:

ClassLoader classLoader = getClass().getClassLoader();
InputStream input = classLoader.getResourceAsStream("your absolute path ");

this might helpful.

CLASSPATH resources need to be under WEB-INF/classes. Please put the config files under src/main/resources for a maven project.

Alternatively, resources directly under WEB-INF are accessible via ServletContext#getResourceAsStream(String path).

At the moment .config files are in Webcontent folder, where I should put them? – Stefano Maglione Sep 21 '20 at 13:14
`src/main/resources` provided it is a maven project? the default package of Java classes if it is not a maven project. – Michal Sep 21 '20 at 13:19
I do not have src/main/resources but I have projectName/resources/, what to do? – Stefano Maglione Sep 21 '20 at 13:22
