我为Web服务创建了一个轴客户端。我作为jar导出并包含在shared / app文件夹中，以便所有portlet应用程序都可以使用它。问题是，当我的portlet项目尝试初始化客户端时，我得到以下异常：
ERROR [org.springframework.web.portlet.DispatcherPortlet] - Context initialization failed

有什么想法吗？我尝试从我的portlet项目引用轴jar，但这不起作用。
答案 0 :(得分：0)
我认为您的客户端jar会干扰标准的websphere库。它导致服务器类加载器层次结构中存在同一类的两个不同版本的情况。您的应用程序类加载器可能选择了错误的版本。
我建议从shared / app中删除jar并改为配置共享库。然后将共享库与应用程序相关联。您可以在was infocenter中找到更多详细信息。
