在JBoss 7上关联EJB和PersistenceUnity之间的依赖关系的错误

Question

在AS JBOSS 7上启动EJB应用程序或者在JBoss AS 7.2上启动EJB应用程序时，在关联EJB和persistenceUnit之间的依赖关系时遇到问题。

行日志错误：

10:07:04,857 ERROR [org.jboss.as.deployment] (DeploymentScanner-threads - 1) {"Composite operation failed and was rolled back. Steps that failed:" => {"Operation step-2" => {"Services with missing/unavailable dependencies" => ["jboss.deployment.unit.\"crm.war\".component.ClienteDAOBean.START missing [ jboss.naming.context.java.module.crm.crm.\"env/br.com.crm.model.dao.ClienteDAOBean/em\" ]","jboss.persistenceunit.\"crm.war#crmUnity\" missing [ jboss.naming.context.java.jboss.datasources/CRMDS ]","jboss.deployment.unit.\"crm.war\".jndiDependencyService missing [ jboss.naming.context.java.module.crm.crm.\"env/br.com.crm.model.dao.ClienteDAOBean/em\", jboss.naming.context.java.module.crm.crm.\"env/br.com.crm.model.dao.ContatoDAOBean/em\" ]","jboss.deployment.unit.\"crm.war\".component.br/com/crm/model/dao/ContatoDAORemote.START missing [ jboss.naming.context.java.module.crm.crm.\"env/br.com.crm.model.dao.ContatoDAOBean/em\" ]"]}}}

下面，遵循XML文件和EJB代码：

的application.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE application PUBLIC "-//Sun Microsystems,Inc.//DTD J2EE Application 1.2//EN" "http://java.sun.com/j2ee/dtds/application_1_2.dtd">

如果您将数据源的别名放在耳边，并将它们配置为standalone.xml，那将是完美的：在理想情况下，您的数据库无关分配。尝试插入standalone.xml此块（我把参数从你的CRM-ds.xml中）：

 <subsystem xmlns="urn:jboss:domain:datasources:1.1"> 
     <datasources> 
      <datasource jta="false" jndi-name="java:jboss/datasources/CRMDS" pool-name="CRMDS" enabled="true" use-ccm="false"> 
       <connection-url>jdbc:hsqldb:file:database/crm</connection-url> 
       <driver-class>org.h2.Driver</driver-class> 
       <driver>h2</driver> 
       <security> 
        <user-name>SA</user-name> 
       </security> 
       <validation> 
        <validate-on-match>false</validate-on-match> 
        <background-validation>false</background-validation> 
       </validation> 
       <statement> 
        <share-prepared-statements>false</share-prepared-statements> 
       </statement> 
      </datasource> 
      <drivers> 
       <driver name="h2" module="com.h2database.h2"> 
        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> 
       </driver> 
      </drivers> 
     </datasources> 
    </subsystem> 

子系统的版本可能是服务器专用的。
