Help with Essbase 9 and the Java API

Question

Hi, I am trying to connect to Essbase from a Java desktop application and I am unable to do so. I need to know if I am in principle doing the right things and if I have the correct environment set up.
We have a server with Essbase version 9.3.1. We normally use essbase via the Excel Addin, and I have already written Excel applications that utilise both the addin and the Essbase VB API. Now I need to connect to Essbase but from outside Excel and using the Java API. I have no idea what APS is nor does my Essbase Administrator.
My application has the following code (adapted from a post in this forum) -
public static void main(String[] args) {
String s_userName = "user";
String s_password = "password";
String s_olapSvrName = "ustca111";
String s_provider = "http://localhost:13080/aps/JAPI";
try{
IEssbase ess = IEssbase.Home.create(IEssbase.JAPI_VERSION);
IEssDomain dom = ess.signOn(s_userName, s_password, false, null, s_provider);
IEssOlapServer olapSvr = dom.getOlapServer(s_olapSvrName);
olapSvr.connect();
System.out.println("Connection to Analyic server '" + olapSvr.getName() + "' was successful.");
olapSvr.disconnect();
}catch(EssException exp){
System.out.println(exp.getMessage());
I am running my application on my computer, not on the Essbase server, and the username I am using is the same one I use (as a user of Essbase) via the Essbase Addin in Excel, not an admin login.
When I run the app I get:
"Cannot connect to Provider Server.Make sure the signon parameters are correct and the Provider Server is running."
Please can you confirm:
1) Do I need an admin login for my client application to connect to the Essbase server or can I use a normal read-access login, like the one I use in Excel?
2) Is the provider always the same regardless of the computer, i.e. "http://localhost:13080/aps/JAPI"; How do I know what this has to be? Where do I get this information from?
3) How can I make sure that the Server is running the necessary "Provider Server", is this just a service that will show on services.msc of the server? What should I ask the Essbase Administrator for him to tell me what I need?
Thank you very much.

Tim, when I look in my computer's Essbase installation path I can only find the following jar files (from the ones you have listed).
C:\Hyperion\AnalyticServices\JavaAPI\external\css\log4j-1.2.8.jar
C:\Hyperion\AnalyticServices\JavaAPI\lib\ess_es_server.jar
C:\Hyperion\AnalyticServices\JavaAPI\lib\ess_japi.jar
I do not have css-9_3_1.jar or interop-sdk.jar.
In order to try the embedded mode, I added the three jars I have to the classpath, and have re-built and ran with "embedded" as the provider. This is what I got in my output screen:
run:

As you can see, this has worked (as I get the data I was looking for at the end), but when I had the url in the provider string, I just get the below, without the initial errors:

Now that I can get both modes to work I intend to write a Windows application, place it in a shared drive, and allow multiple users to use it. Which mode should I use?
By the way, I found the essbase.properties file in C:\Hyperion\AnalyticServices\JavaAPI\bin, but when I add it to my app and test it in embedded mode, I get even more errors, but it still gives me the result...output below:
