From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.4 403 Forbidden
The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated.
If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe
the reason for the refusal in the entity. This status code is commonly used when the server does not wish to reveal exactly why
the request has been refused, or when no other response is applicable.
它不是我们配置不当造成的。
只是应该明白，WebLogic 与Tomcat服务的不同就OK啦。
原因：
未输入完整的访问路径，WebLogic与Tomcat不同，不能显示出目录下的所有文件，
故必须要输入完整的访问路径，例：http://localhost:7001/bea_test/conn.jsp
即地址输入至jsp页面级，即可正常显示！
