Problems with Glassfish5 and servlet

Problems with Glassfish5 and servlet - java

I'm relatively new to Java. Tried my first web application with server Tomcat, which went rather well. However, with another server Glassfish, problems arouse. After application deployment jsp doesn't connect to servlet, therefore error 404 appears. I added project structure and several classes. Any help appreciated.

Problems Creating Login/Registration Page with servlets/MySQL in Eclipse

So here is my issue. I am working on a school project and I am basically hitting a wall. I cannot get my RegistrationServer to work at all. I can get it to run, and correctly display the Registration.jsp that it is built behind, but none of the information is entered into the database at all. In fact, I cannot even tell if that is where exactly I am failing. Here is the code for the Registration function:

Anything anyone can offer as far as why this servlet will not run would be gladly appreciated. The error messages that Eclipse throws are so generic, but the issue seems to be basically writing the registration information to the database. I can load the registration page and enter the information, and the if statements work because the page wont forward with blank text entry boxes or a password less than 6 characters. The problem is when you submit, and it throws HTTP Status 404 and says the requested resource is unavailable.

It might be because you're retrieving the incorrect parameter names in your RegistrationServlet.
For example: you are retrieving with request.getParameter("firstname") but your input have name="firstName". Note the upper case 'N' (java EE servers are case sensitive for URIs).
Try this in your RegistrationServlet:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String firstName = request.getParameter("firstName"); // upper case N
String lastName = request.getParameter("lastName"); // upper case N
String userName = request.getParameter("userName"); // upper case N
String password = request.getParameter("password");
String address = request.getParameter("address");
String contact = request.getParameter("contact");

hibernate print data from session object arraylist

I made wrong HQL trying to access column from another table. Sorry.
This question is solved.
I have ArrayList of type Object. Fetched from session.
It exists. I check. But I cant print it it from jsp or java. even I create methods.
// with type List I cant even fetch information from session. A change it to ArrayList.
My goal is to print result. I select some sql columns and I just wanna output them. Of course it would be object.
I have no error and that is problem. Only existing arraylist object of my type prod.
ArrayList <prod> goodlist = (ArrayList <prod>) session.getAttribute("goodlist_s");
for (prod glst : goodlist) {
%>
<tr>
<td><%//=out.println(u.getname())%></td>
<td><%=glst.getcatid()%></td>}
I try convert it to String ArrayList .
ArrayList<String> jlistTitles = new ArrayList<String>((ArrayList<String>) session.getAttribute("goodlist_s")); //converted fine
for(int i = 0; i < goodlist.size(); i++) {
System.out.println(goodlist.get(i).getprice());
//print object type
}
**Shows nothing**
This is my function
#SuppressWarnings("unchecked")
public static ArrayList<prod> getListOfProds(String catname,String name,Integer pricel, Integer priceh){
ArrayList<prod> list = new ArrayList<prod>();
Session session = HibernateUtil.openSession();
Transaction tx = null;
try {
tx = session.getTransaction();
tx.begin();
Query query = session.createQuery("from prod where catname=?");
query.setString(0, catname);
//query.setInteger(1, pricel);
//query.setInteger(2, priceh);
list = (ArrayList<prod>) query.list();
tx.commit();
} catch (Exception e) {
if (tx != null) {
tx.rollback();
}
e.printStackTrace();
} finally {
session.close();
}
return list;
}
BTW i would sent all code

Here, I m unable to display the list of user from the database table. I not getting any error also.
Serious apology I haven't use MVC because I first want do it using only single java program.
I have added all the necessary jar files.
Please let me know if I m missing anything or not following proper technique/standard.

To use EL syntax to get the value of object Pseudo Getter should be implemented.
So define getter for all element.
${user.fname} implicitly calls user.getFname()

You have not written any getter methods.
EL statement ${user.fname} is like calling user.getFname() and you don't have getter methods.
Define getter methods for all instance variables in Deleteuser.java.
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}
public String getMname() {
return mname;
}
