j_security_check 类似于 weblogic 提供的用于实现 SQLAuthencticatoin 的 servlet。

现在我想从 servlet（我自己的自定义 servlet）中调用 j_security_check servlet，因为我需要在将其路由到 j_security_check 之前执行更多代码。谁能帮我吗 ？

j_security_check is used in Form-Based Authentication. So you can just do a POST to the j_security_check with "j_username" and "j_password". Typically this is done on a JSP, but it could be done within a servlet as well. This part probably isn't news, but as it is a little unclear what your particular issue is, I would recommend that you check out filters and listeners. If you have some code that you want to run through prior to a particular servlet gets called or preforms a particular action, implementing a listener might just do the trick. Conversely, if you care about managing various things prior to a session getting created, perhaps a filter would be useful.
