我是 JBOSS 的新手，我停留在 JBOSS 7.1.1 中应用程序的基本部署中

我创建了一个带有 persistent.xml 的 webapp

<?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，出现以下异常：

我整天都被困在这上面。非常感谢这个论坛的任何帮助。

问候，莱戈拉斯

我下载了Apache Openjpa，提取了 jars，在 jboss 中的 \JBOSS_HOME>\modules\org\apache\openjpa 下创建了一个模块，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。:) 感谢@lurscher 的评论。它激励我继续前进。
