我遇到了一个非常奇怪的错误，我无法绕过头脑。我正在运行Seam 2.2.1.CR2和JBoss 4.3.0.GA.我的申请包括3个模块：
application.xml中
<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>
以下bean已安排并应异步运行。它驻留在我的EJB3模块中：

final Date firstRunIn30sec = new Date(30 * DateUtils.MILLIS_PER_SECOND + System.currentTimeMillis());
indexBean.investigatePendingIndexings(
firstRunIn30sec,
INTERVAL * DateUtils.MILLIS_PER_MINUTE);
}
}
}
当bean引发事件时（也在EJB3模块中）引发事件：
package com.coolwebpp.search.util;

}
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) {

}

<persistence:managed-persistence-context name="entityManager"
auto-create="true"
entity-manager-factory="#{entityManagerFactory}"/>
<persistence:entity-manager-factory name="entityManagerFactory"
persistence-unit-name="theDatabase"/>
当我启动应用程序并且踢脚板开始时，一切正常，直到
getFullTextEntityManager(entityManager).index(company);
然后抛出以下异常：

fulltextentitymanager来自hibernatesearch-3.0.1.GA。
如果我删除调用.index的行，保存实体的工作（em.persist（new CompanyInNeedOfIndexing（company，getNodeName（）））;），但前提是我将范围设置为APPLICATION。
你有什么想法，为什么这不起作用？您有任何提示或者您是否需要更多信息？
答案 0 :(得分：6)
简答：
检查hibernatesearch.jar和quartz.jar是否在default/lib（或<yourserver>/lib）的同一个库目录中。
您可能quartz.jar来自quartz-ra.rar，这也应该有效。但是，如果您不需要quart-ra.rar工具，我建议您将其删除并将quartz.jar放入default/lib。
答案很长：
当您配置Quartz调度程序以管理Seam中的异步作业时，这些作业将在启动时创建的石英线程池中运行。 Java EE中有很多依赖于Thread.currentThread().getContextClassLoader()的逻辑，因此池中的线程与正确的类加载器相关联至关重要。
您应该避免的是重用通常由JBoss中默认安装的quartz-ra.rar模块创建的线程池。
这里有两种选择。要么删除quartz-ra.rar模块（如果不需要）并将quartz.jar放在server / lib中，要么为应用程序配置自定义石英配置，在应用程序类路径的根目录中创建seam.quartz.properties文件。
在自定义seam.quartz.properties中，您定义的实例名称与默认实例名称不同，以便您的应用程序继续使用其私有线程池：
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
无论如何，创建seam.quartz.properties是一个好主意，因为您可以调整其他一些石英参数，例如threadCount。
