Maven构建环境中的Atomikos+Jetty-类加载器问题?

我正在从事一个有多个JDBC数据源和JTA的项目。我使用Maven作为构建工具,我希望在开发过程中使用Jetty插件(6.1.20)来运行应用程序。

Atomikos 作为事务管理器。我在跟踪调查 Atomikos documentation from Jetty ,但Jetty启动失败,看起来像是类装入器问题。

runtime my中的范围依赖关系 pom.xml :

<dependency>
    <groupId>com.atomikos</groupId>
    <artifactId>transactions-jta</artifactId>
    <version>3.5.7</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>com.atomikos</groupId>
    <artifactId>transactions-jdbc</artifactId>
    <version>3.5.7</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>jta</artifactId>
    <version>1.1</version>
    <scope>runtime</scope>
</dependency>

我的 jetty-env.xml 位于 /WEB-INF (码头自动发现):

<New id="userTxImpl" class="com.atomikos.icatch.jta.UserTransactionImp" />

<New id="tx" class="org.mortbay.jetty.plus.naming.Transaction">
    <Arg>
        <Ref id="userTxImpl" />
    </Arg>
</New>

tx 最后是失败的部分,如果我忽略它,Jetty启动良好(但不会暴露) UserTransaction 当然是通过JNDI)。

这看起来像是一个类加载器问题,如下所示 org.mortbay.jetty.plus.naming.Transaction 有一个构造函数正在执行 javax.transaction.UserTransaction 和 com.atomikos.icatch.jta.UserTransactionImp 工具 javax.transaction.UserTransaction 然而,Jetty抱怨它没有合适的构造器来使用。

很明显我遗漏了一些东西,但那是什么?

谢谢
