我已经在 linux ubuntu 服务器上安装了 weblogic 11g。我已经在 weblogic 上部署了我的 web 服务。当我试图从 SOAP UI（安装在我的本地窗口机器上）访问我的 web 服务时，我得到了下面提到的异常。

我的类路径中有我的 jks 文件。经过一番谷歌搜索后，我发现 Rampart 正在查看错误的 cacerts 文件，如下所示：

我在我的 services.xml 中添加了属性，但我仍然遇到同样的错误。我添加了以下属性：

<ramp:property name="org.apache.ws.security.crypto.merlin.load.cacerts">false</ramp:property>

请注意，当 web 服务部署在安装在 windows 环境中的 weblogic 上时，一切正常。

请帮助我确定我缺少什么。

提前致谢。
