頭を包むことができない非常に奇妙なエラーに遭遇しました。Seam 2.2.1.CR2 と JBoss 4.3.0.GA を実行しています。私のアプリケーションは3つのモジュールで構成されています:

アプリケーション.xml

<display-name>CoolWebApp</display-name>
    <module id="EJB3">
        <ejb>EJB3.jar</ejb>
    </module>
    <module id="WEB">
        <web>
            <web-uri>WEB.war</web-uri>
            <context-root>/</context-root>
        </web>
    </module>
    <module>
        <ejb>jboss-seam-2.2.1.CR2.jar</ejb>
    </module>

次の Bean はスケジュールされており、非同期で実行する必要があります。それは私の EJB3 モジュールにあります:

            Events.instance().raiseEvent(CompanyTouched.EVENT_NAME, company, em);
            em.persist(new CompanyInNeedOfIndexing(company, getNodeName()));
        }
    }

    private String getNodeName() {
        return "N0";    // TODO get from -D param
    }

    @Startup(depends = {"applicationBean", "entityManager"})
    @Scope(ScopeType.APPLICATION)
    @Name("indexBeanKicker")
    public static class Kicker {

        private final long INTERVAL = 15;


        @In
        private IndexBean indexBean;

        @Create
        public void initBean() {
            log.info("Will check for indexing every " + INTERVAL + " minutes.");
            final Date firstRunIn30sec = new Date(30 * DateUtils.MILLIS_PER_SECOND + System.currentTimeMillis());
            indexBean.investigatePendingIndexings(
                    firstRunIn30sec, 
                    INTERVAL * DateUtils.MILLIS_PER_MINUTE);
        }
    }

}

イベントが発生すると、次の Bean がそれを取得します (EJB3 モジュールでも):

package com.coolwebpp.search.util;

    public IndexUtils() {

    public static FullTextEntityManager getFullTextEntityManager(EntityManager entityManager) {
        if (entityManager instanceof FullTextEntityManager)
            return (FullTextEntityManager) entityManager;
        else
            return Search.createFullTextEntityManager(entityManager);
    }

    private void reindexWithoutModifyingLastUpdated(Company company, EntityManager entityManager) {
        log.warn("--------------->>> Reindexing without updating lastModified: " + company.getName());
        getFullTextEntityManager(entityManager).index(company);
    }

    @Observer(CompanyTouched.EVENT_NAME)
    public void handleCompanyTouched(Company owningCompany, EntityManager entityManager) {
        reindexWithoutModifyingLastUpdated(owningCompany, entityManager);
    }

}

components.xml

<persistence:managed-persistence-context name="entityManager"
                                           auto-create="true"
                                           entity-manager-factory="#{entityManagerFactory}"/>

  <persistence:entity-manager-factory name="entityManagerFactory"
                                      persistence-unit-name="theDatabase"/>

アプリケーションを起動してキッカーが作動すると、すべてがうまく機能するまで

getFullTextEntityManager(entityManager).index(company);

次に、次の例外がスローされます。

fulltextentitymanager は hibernatesearch-3.0.1.GA から来ています。

エンティティを保存する .index を呼び出す行を削除すると ( em.persist(new CompanyInNeedOfIndexing(company, getNodeName())); )、スコープが APPLICATION に設定されている場合にのみ機能します。

これがうまくいかない理由はありますか？ヒントはありますか、それとももっと情報が必要ですか?

簡潔な答え：

hibernatesearch.jarとquartz.jarが同じライブラリ ディレクトリにあるかどうかを確認します。つまり、両方ともdefault/lib(または<yourserver>/lib) にあります。

あなたはquartz.jarから来ているかもしれませんquartz-ra.rar、それもうまくいくはずです。ただし、施設が必要ない場合は、quart-ra.rar削除して入れることをお勧めしquartz.jarますdefault/lib。

長い答え:

Seam で非同期ジョブを管理するように Quartz ディスパッチャーを設定すると、そのジョブは起動時に作成される Quartz スレッドプールで実行されます。Java EE には依存する多くのロジックがあるThread.currentThread().getContextClassLoader()ため、プール内のスレッドが正しいクラスローダーに関連付けられていることが重要です。

避けるべきことはquartz-ra.rar、JBoss にデフォルトでインストールされるモジュールによって一般的に作成されるスレッド プールを再利用することです。

ここには 2 つのオプションがあります。モジュールを削除quartz-ra.rar(不要な場合) し、quartz.jar を server/lib に配置するか、アプリケーション クラスパスのルートに seam.quartz.properties ファイルを作成してアプリケーションのカスタム Quartz 設定を構成します。

カスタムseam.quartz.propertiesでは、デフォルトとは異なるインスタンス名を定義して、アプリケーションがプライベート スレッド プールを使用し続けるようにします。

org.quartz.scheduler.instanceName = MyApplicationQuartzInstance
org.quartz.scheduler.instanceId = 1
org.quartz.scheduler.rmi.export = false
org.quartz.scheduler.rmi.proxy = false

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5

seam.quartz.propertiesのような他のクォーツ パラメータを調整できるため、とにかく を作成することをお勧めしますthreadCount。
