AllegroGraph Client HTTPException



我正在尝试使用Windows上的AllegroGraph客户端(版本4.1.1)将*.nt文件导入AllegroGraph。我使用 AllegroGraph WebView 应用程序来启动服务器。首先,我尝试创建一个连接、一个目录和一个存储库。创建存储库后,我的系统会抛出com.franz.agraph.http.exception.AGHttpException

这是我的源代码:

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);
        }

输出:

86号线是

AGRepository myRepository = catalog.createRepository(REPOSITORY_ID);

我如何运行它:
1) 运行 agwebview.exe --port 8080
2) 等待服务器启动
3)运行Java类
我已经用谷歌搜索了一个解决方案,并查看了createRepository()命令的javadoc,但找不到任何解决方案。什么可能导致这种行为,我该如何解决它?
我的操作系统是Windows 7 SP 1,java类运行JDK 1.6

通过切换到Linux并使用最新的AGWebView版本来修复它。后来我发现,我最初将AG 4的客户端用于AG 3.3服务器。

对于遇到此问题的任何其他人:确保使用正确的 JAR 文件
