jsp http 404 error , try the method

N I do this for several days , the Internet, said something to solve a lot of problems , but the last question , the database is not connected .
I basically have put online can provide information about my reasons for this fault may have been tried , do not work , but unfortunately can only ask questions.

I want my various configuration details , listed below , hoping to understand friends can help me , thank you very much !

I use Myeclipse10 + tomcat6 + mysql

I think the function is very simple , is to fill out a registration page jsp . The data is then stored to the database. It's that simple

static jsp pages can be opened , but once I clicked submit , the will at http 404 error not available

This is the situation to start tomcat6

------ Solution ----------------------------------- ---------
form expression should not be a post submission method you
------ Solution ------------------- -------------------------
is estimated that you have several applications under tomcat submission address not add a slash "/" ; it

changed

------ Solution ------ --------------------------------------
you this question is really very simple way said first aciton there do not add / , your configuration is not wrong, mostly your submission using the get method, and submit to the background after you get there because there is no code block , it is blank , so that request is not completed it , you get a code block inside with one on it.
doPost (request, response); so ok ah
to the sub yo, follow me can solve

get or post is not the key issue
------ For reference only ---- -----------------------------------

get or post ; 's not the point  

At least you get to submit the page ,
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
}
doGet there should be operating it

http404 solve the problem , thank you !
But now I fill out the registration information, click submit display is blank , to go to view the database table did not respond .
my servlet in connection statement is : Connection conn = DriverManager.getConnection ("jdbc: mysql :/ / localhost: 3306/workdiary", "root", "123456" ) ;
This is my inside workdiary name of the database , the database name is under the table registerinf, I will not be writing these two problems ?
------ For reference only -------------------------------------- -
Click Submit display is blank , to go to view the database table did not respond . There may be questions submitted transaction , executed again when you put your last transaction auto-commit ,
PS database connection is not closed, the result set not related

yes ah, here refers to the doPost method should go inside .
You can try to break inside , since the 404 has been resolved , I think this next breakpoint you can own it . It is not enough, you can see there is no connection Connection problem .
------ For reference only -------------------------------------- -
first SQL statement COPY MYSQL management tools to run in next see if I can insert,

Or conn is null not even on the printed look under conn is not null

Or print out sql splicing error sql, COPY MYSQL management tools to run in under the watch can not be inserted

Or exterior field requires mandatory and did not pass over the value



------ For reference only ---------------------------------- -----
add, because you do is log in , so it is best to use the post method to submit data, or else you get used submission , others will see your data , of course, if you are like they saw it, then I would be no problem
