我正在使用struts2-jquery pluglin。它需要互联网连接。只要我有互联网连接，它就能完美运行。每当我尝试运行没有互联网连接的项目时，都会出现以下错误

答案 0 :(得分：1)

@Commenters：我不明白为什么你不把这个作为答案。

通常jQuery插件不需要互联网连接，除非您在HTML代码所在的JSP的loadFromGoogle="true"标记中设置了属性<sj:head>，否则它应该在本地工作而不会出现问题。如果您这样做，则<sj:head>会被转换为带有<link>的HTML代码到Google服务器上的文件，只有在您拥有互联网连接时才会有效。

如果这不是问题，我只能想象两个。

1）我从未见过这一行，我也在Eclipse中使用Tomcat 7开发（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.但我不认为这就是问题所在。

2）在servlet中有业务逻辑，试图连接到Internet资源，这可能不起作用;因为异常会在一个万无一失的JRE类中被抛出，所以它不会失败。
