@Commenters运行我的项目：我不明白你为什么不把这个作为一个答案。

通常jQuery插件并不需要互联网连接，它应该在本地没有问题，除非你已经在你的HTML代码所在的JSP的<sj:head>标签设置的属性loadFromGoogle="true"工作。如果您这样做了，那么<sj:head>会被转换为HTML代码，并将<link>转换为Google服务器上的文件，该文件只有在您连接到互联网时才能使用。

如果这不是问题，我只能想象两个。我从来没有见过这一行，而且我也在Eclipse中开发了一个Tomcat 7（尽管到目前为止我没有使用Tomcat的更新19）：WARNING: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:airtel' did not find a matching property.但我不认为这是问题。

2）你有一个servlet中的商业逻辑，试图连接到互联网资源，这可能不工作;因为异常被扔在一个万无一失的JRE类中，它不应该失败。
