[Seasar-user:21588] Action実装構成の質問

[Funa]

こんにちは。

Actionの実装構成について質問があります。
現在、Ajax用のActionと画面遷移(Submitを介した)のActionを分けたActionクラ
ス構成にしています。

操作性を良くする為、データの取得・更新系は全てAjax実装です。

そこで、常に起きている訳ではなく、画面をしばらく放置してAjax通信を行うと
以下のExceptionが良く出ます。
ただ、同じ動作は繰り返すと再び正常に動きます。

これはAction構成の問題でしょうか？
と言うのも同じActionクラスに複数のService層を配置しています。
本来、他の画面で使われるexecuteのメソッドも同じクラスに置いています。

複数の使わないテーブルのDBコネクションを保持したこういう構成は
パフォーマンス面でもあまり良く無いのでしょうか？

初歩的な質問で申し訳ありませんが、
お聞かせいただければ幸いです。

public class AmntAction extends ActionBase {

@Resource
protected SoshikiMstService soshikiMstService;

@Resource
protected CategoryMstService categoryMstService;

@Resource
protected UserMstService userMstService;

@Resource
protected LoginTblService loginTblService ;


// ///////////////////////////////////////////////

@Execute(validator = false)
public String userSearch() throws IOException {
//userMstServiceを使ったユーザ管理画面用
}

@Execute(validator = false)
public String userUpdate() throws IOException {
//userMstServiceを使ったユーザ管理画面用
}

@Execute(validator = false)
public String userDelete() throws IOException {
//userMstServiceを使ったユーザ管理画面用
}

// ///////////////////////////////////////////////

@Execute(validator = false)
public String soshikiSearch() throws IOException {
//soshikiMstServiceを使った組織管理画面用
}

@Execute(validator = false)
public String soshikiUpdate() throws IOException {
　 //soshikiMstServiceを使った組織管理画面用
}

@Execute(validator = false)
public String soshikiDelete() throws IOException {
　 //soshikiMstServiceを使った組織管理画面用
}

　　※他も同等の構成で続く。
}
