Hi habib zare ,
You can do this by manual JDBC connection!! but its having lots of disadvantage !!
For Ex:

For Ex:
<%@ page import ="java.sql.*" %>
<%@ page import ="javax.sql.*" %>
<%
String userid=request.getParameter("user");
session.putValue("userid",userid);
String pwd=request.getParameter("pwd");
Class.forName("com.mysql.jdbc.Driver");
java.sql.Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","root");
Statement st= con.createStatement();
ResultSet rs=st.executeQuery("select * from users where user_id='"+userid+"'");
if(rs.next())
{
if(rs.getString(2).equals(pwd))
{
out.println("welcome"+userid);
}
else
{
out.println("Invalid password try again");
}
}

You can just a method in Impl class corresponding to the database table class. If it's a liferay table, you probably won't have problem.
Example
UserLocalServiceImpl.dynamicQuery()
Example
UserLocalServiceImpl.dynamicQuery()

And you don't want to use service builder. So did you code dynamicquery and customquery methods yourself? If you did, you can just call that.

Yes Hitoshi.
I can call customquery in my finderimpl class when i use servicebuilder like :
but if there is no servicebuilder ,i can`t.
i can`t use openSession().
i want any example to learn.
thx.

Session session = null;
session = openSession();
String sql = CustomSQLUtil.get("com.habib.findByName");
SQLQuery q = session.createSQLQuery(sql);
QueryPos qPos = QueryPos.getInstance(q);
return q.list(true);
}

That's simply because you didn't create a method. Create it.
How else did you think you can call on a function without generating it or creating it yourself.
