How to programmatically login to j_security_check

Question

I have a JSP web application which uses `j_security_check`. Is it possible to login a specific user to `j_security_check` programmatically via a JSP page if I know the userid and password? I tried to pass the variables as URL parameters this way... ``` response.sendRedirect(www.mydomain.com/j_security_check?j_username=someUserName&j_password=somePassword ) ``` ...but it doesn't work. Is there any way to do it? Edit: here is my login page which works fine right now. I trimmed some of the code for security reasons. ```

Accepted Answer

The following code works for me in the JSP file:

```
String url = "j_security_check?j_username=" + username + "&j_password=" + password;
String redirectUrl = response.encodeRedirectURL(url);
response.sendRedirect(redirectUrl);
```
