Read Resource file "RDMFieldDictionary" have some problem

In this method

QSConsumer.java

public void init()
    {
    	String fieldDictionaryFilename = "../etc/RDM/RDMFieldDictionary";
    	String enumDictionaryFilename = "../etc/RDM/enumtype.def";
    	try 
    	{
    		GenericOMMParser.initializeDictionary(fieldDictionaryFilename, enumDictionaryFilename);
    	}
    	catch (DictionaryException ex) 
    	{
    		System.out.println("ERROR: Unable to initialize dictionaries");
    		System.out.println(ex.getMessage());
    		if(ex.getCause() != null)
    			System.err.println(": " + ex.getCause().getMessage());
    		cleanup();
    		return;
    	}

    }

STEP1:

In this source code ,it wants to read RDMFieldDictionary ,

String fieldDictionaryFilename = "../etc/RDM/RDMFieldDictionary";

and i change the code to get the file's path like this

String fieldDictionaryFilename = Thread.currentThread().getContextClassLoader().getResource("rfa/RDMFieldDictionary").getFile();

and i got the result like this

/D:/workspace/xuntou-base-market/xuntou-base-market-facade/target/classes/rfa/RDMFieldDictionary

STEP2:

i start the project user Intellij (a IDE like Eclipse) in my own computer, it runs very well

public class RfaSubscribeThread implements Runnable{

    public void run() {

        // Create a demo instance
        QSConsumer demo = new QSConsumer();

        // Startup and initialization
        demo.init();
	//...
    }
}

STEP3:

But when the project has become a Jar File,and start up on the Linux Mechine ,it give me some wrong info like this

ERROR: Unable to initialize dictionaries
ERROR: Check if files file:/usr/local/xuntou/base-market/xuntou-base-market-facade/lib/xuntou-base-market-facade-1.1.9-SNAPSHOT.jar!/rfa/RDMFieldDictionary and file:/usr/local/xuntou/base-market/xuntou-base-market-facade/lib/xuntou-base-market-facade-1.1.9-SNAPSHOT.jar!/rfa/enumtype.def exist and are readable.
: Dictionary file file:/usr/local/xuntou/base-market/xuntou-base-market-facade/lib/xuntou-base-market-facade-1.1.9-SNAPSHOT.jar!/rfa/RDMFieldDictionary does not exist.
RWF: 14.1
RFA: Version = 8.1.0.E2.all, Date = Wed May 02 18:30:50 CST 2018, Jar Path = /usr/local/xuntou/base-market/xuntou-base-market-facade/lib/rfa-1.0.0.jar, Jar Size = 1619345


class com.xuntou.platform.market.rfa.quickstart.QuickStartConsumer.QSConsumer exiting

STEP4:

I seach the internet ,fount in the jar file , use "new File("FilePath")" to get file is not right

i want to change ,but the source code

GenericOMMParser.initializeDictionary(fieldDictionaryFilename, enumDictionaryFilename);

only use "new File('FilePath')" to read the resource file

So, what can i do to avoid the problem.

TIPS: I can't change the source code, it's provided by your company

expect your help, thank you very much!
