我正在通过 Java SOA 库与 Teamcenter 和 Catia 合作。我遇到了演示代码出现损坏的问题，我找不到一个好的示例或文档来解决。以下代码导致空值异常。特别是“session = PortalContext.getContext().getSession();”这一行 是我崩溃的地方。

获取 TCSession 有两种方式。

1）如果您编写富客户端插件

//numTry - number of attemts    
private static TCSession getCurrentSession(int numTry) throws Exception {
        try {
            TCSession session = null;
            ISessionService iss=null;
            int numtry=numTry;
            while (iss==null && numtry>0) {
                iss = AifrcpPlugin.getSessionService();
                numtry--;
            }

            session=(TCSession)iss.getSession("com.teamcenter.rac.kernel.TCSession");
            return session;
            } 
        catch (Exception ex) {
            throw ex;
        }
    }

2) 如果您编写一个独立的应用程序，使用 SOA 与 Teamcenter API 一起工作。

在这种情况下，您需要先连接 teamcenter。有关详细信息，请查看文档中的“HelloTeamcenter”示例。

你有解决方案吗？

SampleIndependentSilentLUS 是自动化 LUS 流程的一种非常好的方法。但我更喜欢使用可以从命令行调用的其他类（SampleSilentLUS），因为 TCIC 将自动提供 TCSession

您从 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。

但是如果您使用松散的服务（com.teamcenter.services.loose.core），我认为您可以简单地类型转换为 TCSession
