我正在尝试在我的应用程序中运行嵌入式 ApacheDS。阅读后：运行嵌入在我的应用程序中的 Apache DS 和http://directory.apache.org/apacheds/1.5/41-embedding-apacheds-into-an-application.html

使用最后一个稳定版本 1.5.7，这个简单的例子在执行“service.startup();”时失败了

Exception in thread "main" java.lang.NullPointerException
    at org.apache.directory.server.core.schema.DefaultSchemaService.initialize(DefaultSchemaService.java:380)
    at org.apache.directory.server.core.DefaultDirectoryService.initialize(DefaultDirectoryService.java:1425)
    at org.apache.directory.server.core.DefaultDirectoryService.startup(DefaultDirectoryService.java:907)
    at Test3.runServer(Test3.java:41)
    at Test3.main(Test3.java:24)

也就是说，DefaultSchemaService.getSchemaManager() 返回 null。

源代码：

public class Test3 {

    public static void main(String[] args) throws Exception {
        runServer();
        testClient();
    }

    static void runServer() throws Exception {
        DefaultDirectoryService service = new DefaultDirectoryService();
        service.getChangeLog().setEnabled(false);

        Partition partition = new JdbmPartition();
        partition.setId("apache");
        partition.setSuffix("dc=apache,dc=org");
        service.addPartition(partition);

        LdapServer ldapService = new LdapServer();
        ldapService.setTransports(new TcpTransport(1400));
        ldapService.setDirectoryService(service);

        service.startup();

        // Inject the apache root entry if it does not already exist
        try {
            service.getAdminSession().lookup(partition.getSuffixDn());
        } catch (Exception lnnfe) {
            DN dnApache = new DN("dc=Apache,dc=Org");
            ServerEntry entryApache = service.newEntry(dnApache);
            entryApache.add("objectClass", "top", "domain", "extensibleObject");
            entryApache.add("dc", "Apache");
            service.getAdminSession().add(entryApache);
        }

        DN dnApache = new DN("dc=Apache,dc=Org");
        ServerEntry entryApache = service.newEntry(dnApache);
        entryApache.add("objectClass", "top", "domain", "extensibleObject");
        entryApache.add("dc", "Apache");
        service.getAdminSession().add(entryApache);

        ldapService.start();
    }


    static void testClient() throws NamingException {
        Properties p = new Properties();
        p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        p.setProperty(Context.PROVIDER_URL, "ldap://localhost:1400/");
        p.setProperty(Context.SECURITY_PRINCIPAL, "uid=admin,ou=system");
        p.setProperty(Context.SECURITY_CREDENTIALS, "secret");
        p.setProperty(Context.SECURITY_AUTHENTICATION, "simple");

        DirContext rootCtx = new InitialDirContext(p);
        DirContext ctx = (DirContext) rootCtx.lookup("dc=apache,dc=org");
        SearchControls sc = new SearchControls();
        sc.setSearchScope(SearchControls.SUBTREE_SCOPE);

        NamingEnumeration<SearchResult> searchResults = ctx.search("", "(objectclass=*)", sc);

        while (searchResults.hasMoreElements()) {
            SearchResult searchResult = searchResults.next();
            Attributes attributes = searchResult.getAttributes();
            System.out.println("searchResult.attributes: " + attributes) ;
        }
    }
}

ApacheDS 1.5.x 版似乎不向后兼容。

在 ApacheDS 1.5.4 中调用“service.startup();” 工作正常（但在其他地方失败）。

知道如何使这个例子工作吗？

这个版本的 ApacheDS 需要明确定义工作目录：

service.setWorkingDirectory(new File("data"));

我最近遇到了类似的问题，经过长时间的谷歌搜索，终于找到了有用的东西

使用 1.5.7 的嵌入式 Apache 目录示例

http://svn.apache.org/repos/asf/directory/documentation/samples/trunk/embedded-sample/src/main/java/org/apache/directory/seserver/EmbeddedADSVer157.java

并看看 pom.xml

使用 1.5.7 的嵌入式 Apache 目录的 Pom.xml 示例

希望是帮助！
