いくつかのゲスト レイアウトを larFile (別のインスタンスからエクスポート) から liferay インスタンス (既に installed_and_configured にすることも、新規インストールにすることもできます) にインポートしようとしています。次に、'application.startup.events' を portal-ext.properties ファイル内のこのクラスに指定します。私のlarFileバージョンは時間の経過とともに変化する可能性があるため、サーバーが起動するたびにこれを実行したい. 私のコードは次のとおりです...

File larFile=new File("/Users/grai001/Desktop/default_guest_public_new_light.lar");

//using absolute path for now -need help in accessing the relative path to ${liferay.home}??

Group guestGroup = GroupLocalServiceUtil.getGroup(1, GroupConstants.GUEST);
LayoutLocalServiceUtil.importLayouts(guestGroup.getCreatorUserId(), guestGroup.getGroupId(), false, new HashMap<String,String[]>(), larFile);

//I want them to be a public layouts which are visible to every one even when a user is not logged in - like the default WHAT-WE-DO kind ofpages in liferay6.1 - I am using 6.1GA2 at both ends

これがヌルポインター例外をどのように与えているか、スタックトレースは以下のとおりです..

... 50 more

そして今、LayoutLocalServiceUtil.importLayouts(guestGroup.getCreatorUserId(), guestGroup.getGroupId(), true, new HashMap<String,String[]>(), larFile); つまり...それらをプライベートレイアウトとしてインポートするとうまくいきます-残念ながら、それらをパブリックにして、すべての人に見えるようにしたいです。また、ポータル管理者としてログインし、UI からパブリック レイアウトとしてインポートすることもうまく機能しています。これを自動化された方法で実行したいのですが。

過去 1 週間の私のこの問題を解決しようとしましたが、十分な調査を行いましたが、それでも解決できませんでした。どんな種類の助けも大歓迎です..！

前もって感謝します

}

この機能は、私にとってはうまくいく場合もあれば、うまくいかない場合もあります:)
