Question

我尝试在Windows上使用AllegroGraph Client（版本4.1.1）将* .nt文件导入AllegroGraph。我使用AllegroGraph WebView应用程序启动服务器。首先，我尝试创建连接，目录和存储库。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：

第86行

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-Class
我已经用google搜索了一个解决方案，并查看了createRepository（）命令的javadoc，但无法找到任何解决方案。什么可能导致这种行为，我该如何解决？我的操作系统是Windows 7 SP 1，java-class使用JDK 1.6

运行

Answer 1

通过切换到Linux并使用最新的AGWebView版本来修复它。之后我发现，我最初使用AG 4的客户端作为AG 3.3服务器。

对于遇到此问题的任何人： 确保使用正确的JAR文件
