Axis2 在 WebSphere 7.0中部署的有关问题

Axis2 在 WebSphere 7.0中部署的问题
问题:项目中加入了Axis2的war包,当部署到websphere7.0版本上时,总是报:

解决办法:经过网上的一番搜罗,从Apache的官网上找到了解决方案以及错误出现的原因(http://axis.apache.org/axis2/java/core/docs/app_server.html)

The JAX-WS runtime in WebSphere Application Server is based on a modified version of Axis2 and these classes are visible to application class loaders. This means that when deploying a standard version of Axis2 on WAS 7.0 (and WAS 6.1 with the Web Services feature pack installed), special configuration is required to avoid conflicts with the Axis2 classes used internally by WebSphere. In particular it is necessary to change the class loader policy of the Web module to parent last. However, this is not sufficient because Axis2 creates additional class loaders for modules and services, and these use parent first class loading by default. Therefore, two things must be done to make a standard Axis2 distribution work with WebSphere:

Before deploying the Axis2 WAR, edit the axis2.xml file and set the EnableChildFirstClassLoading parameter to true. Please note that this parameter is only supported in Axis2 1.5.5 or higher. The parameter is already present in the defaultaxis2.xml file included in the WAR distribution, but its value is set tofalse. Therefore it is enough to change the parameter value. After deployment, modify the application configuration to enable parent last class loading for the Web module: in the WebSphere admin console, go the the configuration page for the enterprise application, click onManage Modules and locate the WAR containing Axis2 (in the default WAR distribution, the module is calledApache-Axis2), then change the Class loader order option to Classes loaded with local class loader first (parent last). Note that the class loader policy for the enterprise application itself (which can be specified underClass loading and update detection) is irrelevant, unless a custom EAR distribution is used that includes the Axis2 libraries in the EAR instead of the WAR.

项目采用的Axis2的版本是1.4的,所以上面提到的第一条不适用,当按照第二条的办法处理后问题解决了(in the WebSphere admin console, go the the configuration page for the enterprise application, click onManage Modules and locate the WAR containing Axis2 (in the default WAR distribution, the module is calledApache-Axis2), then change the Class loader order option toClasses loaded with local class loader first (parent last))!
