我在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。当我尝试从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。

我的课程路径中有我的jks文件。经过一些谷歌搜索后，我发现Rampart正在查看错误的cacerts文件，如下面的URL：
http://emelnikov.blogspot.in/2013/04/org.html
我在services.xml中添加了属性，但我仍然遇到同样的错误。我在下面添加了属性：
<ramp:property name="org.apache.ws.security.crypto.merlin.load.cacerts">false</ramp:property>
请注意，在Windows环境下安装的weblogic上部署Web服务时，一切正常。
请帮我确定一下我遗失的内容。
提前致谢。
