问题


I have run into a very strange error that I can´t wrap my head around. I´m running Seam 2.2.1.CR2 and JBoss 4.3.0.GA. My application consist of 3 modules:

application.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>

The following bean is scheduled and should run asynchronously. It resides in my EJB3 module:

package com.coolwebapp.indexing;

import org.apache.commons.lang.time.DateUtils;
import org.jboss.seam.Component;
import org.jboss.seam.ScopeType;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**

@Name("indexBean")
@AutoCreate
public class IndexBean {

    @Logger
    private static Log log;

    /**
     * @return Will fetch an applicationBean
     */
    private EntityManager entityManager() {
        return (EntityManager) Component.getInstance("entityManager", true);
    }

    @SuppressWarnings({"unchecked"})
    @Transactional
    @Asynchronous
    public void investigatePendingIndexings(@Expiration Date when, @IntervalDuration Long interval) {
        log.info("IndexBean.investigatePendingIndexings()");
        final EntityManager em = entityManager();
        List<CompanyInNeedOfIndexing> indexingTasks =
                 em.createQuery(
                        "from CompanyInNeedOfIndexing C where C.hasBeenIndexedOnNode not like :nodeName")
                        .setParameter("nodeName", getNodeName())
                        .getResultList();

        Map<Long, Company> idToCompanyToIndexMap = new HashMap<Long, Company>();
        for (CompanyInNeedOfIndexing indexingTask : indexingTasks) {
            final Company company = indexingTask.getCompany();
            final long id = company.getId();
            if (!idToCompanyToIndexMap.containsKey(id))
                idToCompanyToIndexMap.put(id, company);
        }

        for (Company company : idToCompanyToIndexMap.values()) {
            log.info("Indexing " + company.getName());
            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);
        }
    }

}

When the event is raised following bean picks it up(also in EJB3 module):

package com.coolwebpp.search.util;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.lucene.document.Document;
import org.hibernate.annotations.common.reflection.java.JavaReflectionManager;

import org.jboss.seam.annotations.AutoCreate;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Observer;
import org.jboss.seam.annotations.Scope;
import com.coolwebapp.events.CompanyTouched;
import com.coolwebapp.model.Company;

import javax.persistence.EntityManager;
import java.io.Serializable;

@Name("indexUtils")
@AutoCreate
@Scope(ScopeType.SESSION)
public class IndexUtils implements ArticleSaved, ReviewsUpdated, CompanyPublished, CompanyRemoved, SearchWordsUpdated, CompanyTouched, Serializable {

    public final static Log log = LogFactory.getLog(IndexUtils.class);

    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"/>

When I start the application and the kicker kicks in everything works well until

getFullTextEntityManager(entityManager).index(company);

Then following exception is thrown:

The fulltextentitymanager comes from hibernatesearch-3.0.1.GA.

If I remove the line calling .index saving the entity works( em.persist(new CompanyInNeedOfIndexing(company, getNodeName())); ), but only if I have the scope set to APPLICATION.

Do you have any ideas why this doesn't work? Do you any tips or do you need more information?

Short answer:

Check if hibernatesearch.jar and quartz.jar are in the same library directory, that is both in default/lib (or <yourserver>/lib).

You may have quartz.jar coming from quartz-ra.rar, that should also works. However, if you don't need the quart-ra.rar facilities I suggest you to remove it and put quartz.jar in default/lib.

Long answer:

When you configure the Quartz dispatcher to manage asynchronous jobs in Seam, that jobs run in the quartz threads pool that is created at startup time. There is much logic in Java EE that depends on Thread.currentThread().getContextClassLoader() so it's critical for the threads in the pool to be associated to the correct classloader.

What you should avoid is reusing the thread pool that is commonly created by the quartz-ra.rar module installed by default in JBoss.

You have two options here. Either you remove quartz-ra.rar module (if not needed) and put quartz.jar in server/lib, or you configure a custom quartz configuration for your application creating a seam.quartz.properties file in the root of the application classpath.

In the custom seam.quartz.properties you define an instance name different by the default one, so that your application keeps using her private threads pool:

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

Creating a seam.quartz.properties is a good idea anyway, because you can tune some other quartz parameters like threadCount.
