Jboss中的Axis2.jar冲突

我在部署Axis 2 Web应用程序时遇到问题。我使用的是Jboss 4.2.0，它已经有一个使用Axis 2客户端的Web应用程序。我试图部署的这个Axis 2应用程序实际上是一个归档服务（扩展名为.aar），它放在Axis 2 Web应用程序的“services”文件夹中。后者然后使用蚂蚁生成器构建，生成的.war文件就是我正在部署的。现在，当我从Jboss的deploy文件夹中删除旧的应用程序时，我的新应用程序工作得很好。但是，当我再次重新部署旧的应用程序，从我的Jboss出现以下情况例外：Jboss中的Axis2.jar冲突

我的猜测是，JBoss是上了年纪的的.ear内存在的axis2-1.4.1.jar文件之间发生冲突应用程序以及我试图部署的Axis 2 Web应用程序的axis2.jar。有没有人有我的问题的解决方案？

我能解决这个问题。我最初的假设是正确的：我的问题是，当首先部署包含axis2-1.4.1.jar jar文件的.ear项目时，应用程序的类加载器将自己注册为能够加载所有类的类加载器在.jar文件中找到，因为没有其他类加载器能够为这些类提供服务。 （您可以查看以下链接以获取更多说明： 1“> http://thorgull.be/doku.php?id=tutorials:jboss:classloaderisolation#fnt_1 http://community.jboss.org/wiki/JBossClassLoadingUseCases ）

为了解决这个问题，我创建了一个的jboss-app.xml文件（因为它是一个项目的.ear），并添加以下内容：

<?xml version="1.0" encoding="UTF-8" ?> 
<jboss-app> 
    <loader-repository> 
    mypackage:loader="myapplication.ear" 
    </loader-repository> 
</jboss-app>

随着这一变化，一个独立的子库将被创建用于我的.ear应用程序（这被称为隔离模式）。这将解决有人可能遇到的任何问题，因为拥有不同版本的相同包/类，尝试运行o n是Jboss的同一个实例。

另一种解决方案可能比较简单，但对哪些应用程序隔离以及哪些应该委托给软件包/类的根存储库不提供太多控制，方法是修改ear-deployer.xml（在您的deploy文件夹中找到），以及设置下面的XML元素：

<attribute name="Isolated">false</attribute>

到真。

请务必阅读我在文章中提到的参考资料，以更好地理解类加载器的工作方式。

祝你好运。
