Is there any way that I can do it this way and if so is there a solution to the error I have?
I think you do not want the http:// in there, for a proper URL you would want either MySQL:// -OR- http:// not both.
I am guessing your proper string is going to be :
jdbc:mysql://danu6.it.nuigalway.ie:3306/mydb1899/players
jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]
That is the format for connection URLs. Does yours work with that?

I am new to jsp. I am trying to insert data into the table through a jsp page. My code is running fine all the values are correctly passing to the statement. But, after the last value it should move to the executeUpdate command but it moved to the return command instead which returns 0 and data does not inserted into the database. My code is here.

It's mean that you code executed in the try section failed. Display the stacktrace in the catch section to see errors.
try{
...
}catch(Exception e){
e.printStackTrace()
}
problem has been resolved.. there was a mistake in the query..
"insert into register(uname,ulogin,upass,Gender,ucontact,Email) values(?,?,?,?,'',?)" ..
In my web application, I have a home page where the options available to the user are placed in a fixed sidebar in the top of the screen, and each one of this options are opened inside of a tag <div> in this same page.
My problem is: when this content is a form, and I submit it to the server, after the processing, the output page isn't opened in this <div>, but in the entire navigation space. What I want is a way of capture this return and display it in the same <div> it was originated.
the code for my home page is:

Someone have any thoughts about how to do that?
Well, spring mvc just open new page with a content you set in ModelAndView. If you want to load somthing just in some part of page ( in this case ) there pure javascript / jquery ajax is needed. So steps needed here:
Add javascript which will do ajax request to controller
Controller need to return JSON ( #ResponseBody can help you )
You have to do some DOM manipulation using javascript/jquery to put JSON answer to your div.
I need to take the value of the select option to send it to another page to be processed, but can not capture the value.
any ideas?
the select is loaded from the database, that part works, shows the categories of product.
