How to configure Pentaho Carte to accept HTTPS request instead of HTTP

I have a requirement where Pentaho Carte server needs to accept "HTTPS" instead of the default "HTTP".

I have followed the following link but to no avail:

https://help.pentaho.com/Documentation/6.0/0L0/0Y0/060/060/010#Configuring_Carte_Servers_for_SSL

Following are the steps I followed:

1. Using the Keytool I created a .jks file using the following command:

   keytool -genkey -keyalg RSA -alias selfsigned -keystore   C:\KEY_STORE\Pentaho\keystore.jks -storepass password -validity 360 -keysize 2048

2. I edited the carte_config_master-8080.xml file on my system which now looks as:

   <slaveserver><name>master1</name><hostname>10.67.110.93</hostname><port>8080</port><master>Y</master><sslConfig><keyStore>C:\KEY_STORE\Pentaho</keyStore><keyStorePassword>password</keyStorePassword><keyPassword>password</keyPassword></sslConfig></slaveserver>

   As can be seen I have created the .jks file and mentioned its location in carte-config-master-8080.xml.

3. I am invoking Carte as:

   C:\software\pdi-ce-5.4.0.1-130\data-integration>Carte.bat carte-config-master-8080.xmlDEBUG: Using PENTAHO_JAVA_HOMEDEBUG: _PENTAHO_JAVA_HOME=C:\Program Files\Java\jre7DEBUG: _PENTAHO_JAVA=C:\Program Files\Java\jre7\bin\java.exe

4. Carte is getting invoked but it is not accepting "HTTPS", I guess because of following error:

   validation.properties could not be loaded by any means. fail. Exception was: java.lang.IllegalArgumeclassloader resource.SecurityConfiguration for Logger.LogServerIP not either "true" or "false" in ESAPI.properties. Using2017/02/02 15:33:31 - Carte - Using SSL mode2017/02/02 15:33:31 - Carte - Created listener for webserver @ address : 10.67.110.93:8080Exception in thread "main" java.lang.reflect.InvocationTargetException        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)        at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)        at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)        at java.lang.reflect.Method.invoke(Unknown Source)        at org.pentaho.commons.launcher.Launcher.main(Launcher.java:92)Caused by: java.io.FileNotFoundException: C:\KEY_STORE\Pentaho (Access is denied)        at java.io.FileInputStream.open(Native Method)        at java.io.FileInputStream.<init>(Unknown Source) 

   It can be clearly seen that the folder where the key is saved is inaccessible. I have given full access rights to the folder.

P.S. - Working on Pentaho Kettle Community Edition 5.4 & Windows 7

Any suggestions?
