Import user defined class not working
Hello all,
Im trying to import a class into a JSP file.
At the beginning I got the an error saying "Generated servlet error:
Only a type can be imported. SDTDeal resolves to a package"
After a lot of googling I found I wasn't placing my class files in the
WEB-INF\classes\ directory and my classes weren't public. But after I
fixed all of that I got the following error:
"An error occurred at line: 113 in the jsp file: /SD Tool/CheckNew.jsp
Generated servlet error:
SDTDeal cannot be resolved"
I heven't find a way to solve this issue since the error message is too
general. Can somebody please give me some help at least to get me going
on to how to solve this problems.
P.S. Here is the JSP code:
<%@ page import="java.sql.*" %>
<%@ page import="java.io.*" %>
<%@ page import="SDT.SDTDeal" %>
<%String connectionURL =
"jdbc:microsoft:sqlserver://HLEVEL1:1433;databasename=sdt";
Connection connection = null;
Statement statement = null;
PreparedStatement insert= null;
ResultSet rs = null;
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstanc
e();
connection = DriverManager.getConnection( connectionURL, "harol3",
"toto2409"); statement = connection.createStatement();
String user = request.getParameter("user"); String password =
request.getParameter("password"); String
name=request.getParameter("name");
String company=request.getParameter("company");
int day=Integer.parseInt(request.getParameter("day"));
int month=Integer.parseInt(request.getParameter("month"));
int year=Integer.parseInt(request.getParameter("year"));
String checkbox=request.getParameter("checkbox");
boolean fail=false;
if(name.trim().equals(""))
{
fail=true;
%>
</p>
<p><span class="style7">Fill in the name of the Deal </span></p>
<p>
<%
}
else
{
rs = statement.executeQuery("SELECT name FROM deals WHERE name
LIKE '"+name.trim()+"'");
if(rs.next())
{
fail=true;
%>
</p>
<p><span class="style7">This name is being used by
another deal </span></p>
<p>
<%
}
}
if(company.trim().equals(""))
{
fail=true;
%>
</p>
<p><span class="style7">Fill in the Company Name</span></p> <p>
<%
}
if(checkbox==null)
{
if((month==4||month==6||month==9||month==11)&&day==31)
{
fail=true;
%>
</p>
<p><span class="style7">The selected month does not have
31 days</span></p>
<p>
<%
}
if(month==2&&day>28)
{
fail=true;
%>
</p>
<p><span class="style7">The selected month have less
than 29 days</span></p>
<p>
<%
}
}
if(fail)
{
%>
</p>
<form action="New.jsp" method="post" name="form1"

insert.executeUpdate();
%>

Looks like you're developing without using a good IDE. Not using one is actually more time consuming and difficult than using one for java web development. Besides you will pickup the structure more easily, and it will be in a portable .war file. I suggest Netbeans. It's free.
Also, look into MVC2 architecture, so you won't need to expose your db password. After all a jsp is a text file.

You should have
WEB-INF\classes\SDT\SDTDeal.class
Is that so?
BTW: case matters.
