java如何打开TCSession？
我正在通过Java SOA库与Teamcenter和Catia合作。我遇到了一个问题，演示代码似乎有问题，我找不到一个好的例子或文档来解决。以下代码导致空值异常。特别是“session=PortalContext.getContext（）.getSession（）；”一行这就是我要崩溃的地方

你找到解决办法了吗
SampleIndependentSilentLUS是一种非常好的自动化LUS过程的方法。但我更喜欢使用可以从命令行调用的另一个类（SampleSilentLUS），因为TCIC将自动提供TCSession
从SOA获得的会话对象（com.teamcenter.services.strong.core._2008_06.session）与RAC会话（com.teamcenter.RAC.TCSession）不兼容
但如果您使用松散服务（com.teamcenter.services.loose.core），我认为您可以简单地将其键入TCSession
