Get data from Login form on webpage

Hi guys, I'm using this guide and creating a login page for my site. I am using a jdbc-odbc bridge and have changed the connection. What I can't figure out is how to get the data from the bean to the login class (the class that connects to the database.

Whenever I try to run the site, I get the error message

org.apache.jasper.JasperException: /jspbeanlogin/loginbean.jsp(9,57) Attribute value request.getParameter("userName") is quoted with " which must be escaped when used within the value
org.apache.jasper.compiler.DefaultErrorHandler.jsp Error(DefaultErrorHandler.java:40)

Can you post your version of loginbean.jsp? It sounds like it is a simple fix.

The problem you're having is a common one - you've incorrectly nested your double quote characters. The code:

is actually invalid. Why? When you specified the "value" parameter you used double quotes to open the HTML value and then double quotes to open the Username parameter.

Instead, use something like:

The only change there is that I'm using single quotes around the "value" as opposed to double quotes.

Notice that even the code formatter in the forum highlights this differently.

I did this, but I get this error message now

That class is the same as the website loginbean.java.

Even with this, I can't see where in the login.java file on the roseindia.net page that it takes the data from the above bean and uses it to check with the database.

You've got a case issue. Use

to set the property. JSP will be looking for "setUsername" with that call and that is what you want.
