技术要点：未来方向北美平台

周二系统技术主题图层设置未来方向或Java ase、EE和我.和邮件发送失败。第二天，javainnovationand cutting dgedvancegreback。如果。网线我们被比作其他帝国的删除线回来，然后绝地武士的爪哇1.5分钟.

现在，当开发人员想要的时候，他们正在寻找一个全新的项目。今天，系统技术关键说明了新的优先级提高开发人员的工作效率（开发人员的工作效率)和构建框架，简化了开发人员每天重复的任务，除了传统的优先级之外，还提供了性能，增加了功能，并提高了必要的.

TS-1102:J2EEor .NET-anobjectvetechnologyccomparison

如果你有这样的想法，你可能会想，你会有目标吗？这种希望将被扼杀在摇篮里，就像我们的英国演讲者开始说不出话一样，实际上是为了实现一个目标而采取的行动。更愚蠢！这种对话非常简单有趣，与那些只是想编码但却不愿意展示自己的开发人员大相径庭presenterworkedforOracle，但他指定了一个日志。

对话被简单地称为您的经理将会有一个很好的开端. NET。dontletitgetintoyoudevculture！
