編集:解決策が見つかりました。これは、maven ビルド プロセス中にコードを縮小する際の問題でした。Java アプレットで OrientDB を実行することが可能です。
Java アプレットでインメモリ OrientDB を起動する際に問題があります。OrientDB バージョン 1.0.1 で署名付きアプレットを使用しています。誰かが OrientDB をアプレットに実装し、これが可能であること、またはこの例外で私を助けることができることを確認できますか?
私が得る例外:

DBを開始するための私のアプレットコード:
public class Applet extends java.applet.Applet {
OrientDbConfigurationLoader configLoader = null;
OServer server = null;
ODatabaseDocumentTx db = null;
@Override
public void init() {
AccessController.doPrivileged(new
PrivilegedAction<OServer>() {
public OServer run() {
configLoader = new OrientDbConfigurationLoader("db/", "test");
try {
server = OServerMain.create();
server.startup(configLoader.loadDefaultConfig());
server.activate();
} catch (InstanceAlreadyExistsException e) {
server = OServerMain.server();
} catch (Exception e) {
System.out.println("Something went wrong while the server should start");
e.printStackTrace();
}
try {
db = new ODatabaseDocumentTx("memory:temp");
db = db.open(OrientDbConfigurationLoader.USERNAME, OrientDbConfigurationLoader.PASSWORD);
} catch (Exception e) {
System.out.println("Can't init the in-memory db.");
e.printStackTrace();
}
return null;
}
});
}
}
