I have a maven project, working on Eclipse IDE. And I am trying to deploy it to the other linux machine having tomcat server, by export .war file from eclipse and put it to the other machine.

Here is the problem, when I execute(?) .war file by tomcat server, it automatically unzipped this file and make a project directory, however my resources in /src/main/resources spreads over var/lib/tomcat7/webapps/{project-root}/WEB-INF/classes and my original code to load some files doesn't work anymore

Here is the example.

String currentDir = System.getProperty("user.dir");
File mappingdir = new File(currentDir + "/src/main/resources/mapping");
File f = new File(mappingdir + "/a.csv");

Result

HTTP Status 500 - java.io.FileNotFoundException:  
/var/lib/tomcat7/src/main/resources/mapping/a.csv (No such file or directory)

Because, this .csv file does not exists anymore. Its location is /var/lib/tomcat7/webapps/{project-root}/WEB-INF/classes/mapping/a.csv

How should I change the directory while developing java standalone code - if I consider deploy it to the web server?

My question is very much related to this question. Read file from /src/main/resources/

In java application all source files placed in /WEB-INF/classes folder. To read files from resources you shoul use 

BufferedReader reader = new BufferedReader(
                new InputStreamReader(getClass().getClassLoader().getResourceAsStream("mapping/a.csv")));

it will work with standalone java applications too.
