Question

我是JBOSS的新手，并坚持在JBOSS 7.1.1中基本部署应用程序

我创建了一个带有persistent.xml的webapp作为

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
    xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
    <persistence-unit name="mydummy-jpa" transaction-type="RESOURCE_LOCAL">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
        <jta-data-source>java:jboss/datasources/mydummyexample</jta-data-source>  
        <class>com.nsn.caobusiness.selfcare.entity.DummyTable</class>
        <properties>
            <property name="jboss.as.jpa.providerModule" value="org.jboss.as.jpa.openjpa" />
            <property name="openjpa.Log" value="DefaultLevel=WARN,SQL=TRACE" />
            <property name="openjpa.jdbc.DBDictionary" value="mysql(UseClobs=true)"/>           
        </properties>
    </persistence-unit>
</persistence>

我的standalone.xml中的数据源如下所示：

<datasource jndi-name="java:jboss/datasources/mydummyexample" pool-name="mydummyexample" enabled="true" use-java-context="true" use-ccm="true" jta="true">
                    <connection-url>jdbc:mysql://localhost:3306/worldonstreet</connection-url>
                    <driver>mysql</driver>
                    <security>
                        <user-name>root</user-name>
                        <password></password>
                    </security>
                    <statement>
                        <prepared-statement-cache-size>100</prepared-statement-cache-size>
                        <share-prepared-statements/>
                    </statement>
                </datasource>

当我部署应用程序时，我得到以下异常：

23：48：06,656 INFO [org.jboss.as.jpa]（MSC服务主题1-5）JBAS011401：为mydummy-jpa读取persistence.xml 23：48：08,000 ERROR [org.jboss.msc.service.fail]（MSC服务线程1-1）MSC00001：无法启动服务jboss.deployment.unit。“SpringDatabaseTransaction.war”.INSTALL：org.jboss.msc服务jboss.deployment.unit中的.service.StartException。“SpringDatabaseTransaction.war”.INSTALL：无法处理部署的部分INSTALL“SpringDatabaseTransaction.war” 在org.jboss.as.server.deployment.DeploymentUnitPhaseService.start（DeploymentUnitPhaseService.java:119）[jboss-as-server-7.1.1.Final.jar：7.1.1.Final] at org.jboss.msc.service.ServiceControllerImpl $ StartTask.startService（ServiceControllerImpl.java:1811）[jboss-msc-1.0.2.GA.jar：1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl $ StartTask.run（ServiceControllerImpl.java:1746）[jboss-msc-1.0.2.GA.jar：1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor $ Worker.runTask（ThreadPoolExecutor.java:886)[rt.jar:1.6.0_26] at java.util.concurrent.ThreadPoolExecutor $ Worker.run（ThreadPoolExecutor.java:908）[rt.jar：1.6.0_26] 在java.lang.Thread.run（Thread.java:662）[rt.jar：1.6.0_26] 引起：javax.persistence.PersistenceException：JBAS011466： PersistenceProvider类未找到'org.apache.openjpa.persistence.PersistenceProviderImpl'

我在这一整天都被困住了。非常感谢这个论坛的任何帮助。

我下载了Apache Openjpa，解压缩了jars，在\ JBOSS_HOME＆gt; \ modules \ org \ apache \ openjpa下的jboss中创建了一个模块，并将我在persistent.xml中的属性更改为

  <property name="jboss.as.jpa.providerModule" value="org.apache.openjpa" />

module.xml看起来像：

<module xmlns="urn:jboss:module:1.1" name="org.apache.openjpa"> 
    <resources> 
        <resource-root path="openjpa-2.2.0.jar"/> 
        <resource-root path="serp-1.13.1.jar"/> 
    </resources> 
        <dependencies> 
            <module name="javax.persistence.api"/> 
            <module name="javax.transaction.api"/> 
            <module name="javax.validation.api"/> 
            <module name="org.apache.commons.lang"/> 
            <module name="org.apache.commons.collections"/> 
            <module name="org.apache.log4j"/> 
        </dependencies> 
</module>

它终于奏效了。 :) 谢谢@lurscher的评论。它促使我继续前进。
