AllegroGraph Client HTTPException

Question

I´m trying to import a *.nt File into AllegroGraph by using the AllegroGraph Client (version 4.1.1) on Windows. I use the AllegroGraph WebView application to start the server. First of all, I tried to create a connection, a catalog and a repository. Upon creating a repository, my system throws an com.franz.agraph.http.exception.AGHttpException

This is my source-code:

package mytest;

public class NTLoader {

    public static String SERVER_URL = "http://localhost:8080";
    public static String CATALOG_ID = "";
    public static String REPOSITORY_ID = "test3";
    public static String USERNAME = "me";
    public static String PASSWORD = "xyzzy";
    public static String TEMPORARY_DIRECTORY = "";

    public static void main(String[] args) {
        try {
            // Tests getting the repository up. 
            System.out.println("\nStarting example.");
            AGServer server = new AGServer(SERVER_URL, USERNAME, PASSWORD);
            System.out.println(server.getRootCatalog().getCatalogName());
            AGCatalog catalog = server.getCatalog(server.getRootCatalog().getCatalogName());
            AGRepository myRepository = catalog.createRepository(REPOSITORY_ID);
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }

Output:

Line 86 is

AGRepository myRepository = catalog.createRepository(REPOSITORY_ID);

How I run it:
1) Run agwebview.exe --port 8080
2) Wait for the server to be started
3) Run Java-Class
I´ve already searched fo a solution with google, and looked into the javadoc of the createRepository() command, but couldnt find any solution. What could cause this behaviour and how can I fix it ?
My OS is Windows 7 SP 1 and the java-class runs with JDK 1.6

Fixed it by switching over to Linux and using the most recent AGWebView version. Afterwards I figured out, that Ive initially used the client of AG 4 for an AG 3.3 Server.

For anyone else who encounters this problem: Make sure you use the right JAR-files
