Java NetBeans 7.2，启动maven spring项目并添加hibernate

我正在尝试将maven作为构建系统，以便对依赖项进行更标准的管理

这是我做的步骤和我问的简单问题。这个过程是我所能想到的最简单的，所以这个问题应该很容易重现

让我们从文件、新项目、Maven和Web应用程序开始。 在下面的表单中，我保留了所有的默认值，但对于ApplicationServer字段，我选择了“ApacheTomcat7.0.11.0”。 我注意到这个向导没有提出任何框架（Sring、Hibernate等），而标准的非maven项目创建向导允许框架的选择包括 如果我们现在看看这个项目，下面是我们看到的：



所以第一个问题是：为什么spring已经包括在内，甚至在我明确添加它之前？

让我们看看项目属性：


因此没有选择任何框架。 我只想将spring用于其依赖项注入容器（稍后我可能会添加spring安全性，但这不是目前的优先事项）如前所述，由于已经包含了一些核心模块，我是否需要再次添加它？

在项目属性的框架节点中，我添加了Hibernate，并选择了一个数据库连接。依赖项现在变成如下所示

其中两个（我在屏幕截图中突出显示了它们）被标记为“Dependency not download.Build project to correct errors”（当您将指针移到它们上方时，可以将此消息作为提示）。我已经构建了项目，但错误仍然存在。
在maven的输出中，我看到：

Failed to execute goal on project CreatingMavenSpringProject: Could not resolve dependencies for project com.mycompany:CreatingMavenSpringProject:war:1.0-SNAPSHOT: The following artifacts could not be resolved: javax.sql:jdbc-stdext:jar:2.0, javax.transaction:jta:jar:1.0.1B: Could not find artifact javax.sql:jdbc-stdext:jar:2.0 in unknown-jars-temp-repo (file:C:\Users\agostino\Documents\NetBeansProjects\CreatingMavenSpringProject/lib) -> [Help 1] To see the full stack trace of the errors, re-run Maven with the -e switch.
