DLL not found in jar - java.lang.UnsatisfiedLinkError

[ebreeze]

Hi,

I am having the following problem when trying to use this Java Library https://github.com/kosprov/jargon2-api in Coldfusion 2018 with the JavaLoader:

Typ | java.lang.UnsatisfiedLinkError
Diagnose | Unable to load library 'argon2': Das angegebene Modul wurde nicht gefunden. Das angegebene Modul wurde nicht gefunden. Das angegebene Modul wurde nicht gefunden. Native library (win32-x86-64/argon2.dll) not found in resource path ([file:/D:/ColdFusion2018/cfusion/lib/updates/chf20180010.jar,

The code looks like this:

component name="Argon2Kosprov" output="false" {
	public function init(string pepper = "mySecretIngredient") {

		getJavaLoader();
		
		// More info about the API: https://github.com/kosprov/jargon2-api

		local.jargon2 = variables.javaLoader.create("com.kosprov.jargon2.api.Jargon2");
	
		variables.hasher = local.jargon2.jargon2Hasher();
		
		initConstants();

		variables.hasher.type(variables.argon2Type); 
		
		// Parameters
        variables.hasher.memoryCost(65536);  		// 64MB memory cost
        variables.hasher.timeCost(3);        		// 3 passes through memory
        variables.hasher.parallelism(4);     		// use 4 lanes and 4 threads
        variables.hasher.saltLength(16);     		// 16 random bytes salt
        variables.hasher.hashLength(16);    		// 16 bytes output hash		
		applyPepper(arguments.pepper);
		
		// Just get a hold on the verifier. No special configuration needed.
        variables.verifier = local.jargon2.jargon2Verifier();

		return this;
	}


	public void function applyPepper(required string pepper) {
		
		local.binaryValue = stringToBinary(arguments.pepper);		
		variables.hasher.secret(local.binaryValue);
		
	}


	public string function hashString(required string string) {		
	
		// Set the password and calculate the encoded hash		
		local.binaryValue = stringToBinary(arguments.string);
		
	        local.encodedHash = variables.hasher.password(local.binaryValue).encodedHash();

		return local.encodedHash;		
	}


	public boolean function checkString(required string string, required string hash) {
		// Set the encoded hash, the password and verify
        return variables.verifier.hash(arguments.hash).password(arguments.string).verifyEncoded();
	}


	// private functions	
	private void function initConstants() {		
		local.argon2Types = variables.javaLoader.create("com.kosprov.jargon2.api.Jargon2$Type");				
		final variables.argon2Type = local.argon2Types.ARGON2id
	}
	
		
	/**
	* @hint Load specific .jar files using JavaLoader
	* */
	private component function getJavaLoader() {

		if (NOT StructKeyExists(variables, "javaLoader")) {	
			local.jarArray = [								
				ExpandPath("/jars/net/java/dev/jna/jna/5.6.0/jna-5.6.0.jar"),
				ExpandPath("/jars/com/nativelibs4java/ochafik-util/0.12/ochafik-util-0.12.jar"),
				ExpandPath("/jars/com/nativelibs4java/jnaerator-runtime/0.12/jnaerator-runtime-0.12.jar"),
				ExpandPath("/jars/com/kosprov/jargon2/jargon2-native-ri-backend/1.1.1/jargon2-native-ri-backend-1.1.1.jar"),
				ExpandPath("/jars/com/kosprov/jargon2/jargon2-native-ri-binaries-generic/1.1.1/jargon2-native-ri-binaries-generic-1.1.1.jar"),				
				ExpandPath("/jars/com/kosprov/jargon2/jargon2-api/1.1.1/jargon2-api-1.1.1.jar")
			];
			
			variables.javaLoader = CreateObject("component", "lib.shared.javaloader.JavaLoader").init(local.jarArray);
		
		}

		return variables.javaLoader;
	}


	private any function stringToBinary(required string) {		
		local.base64Value = toBase64(arguments.string);
		local.binaryValue = toBinary(base64Value);
		return local.binaryValue;
	}
	
}

and it is called like this:

 <cfset local.argon = new lib.shared.argon2.Argon2Kosprov()>
 <cfset local.password = "alabala"> 
 <cfset local.hash = local.argon.hashString(local.password).encodedHash()>

Then comes the exception saying the the DLL is not found. The DLL is in the JAR and should not be separately loaded.

Any help would be appreciated. Thanks.
