Problem with war file and tomcat 7

General
1

Hi, can somebody help me?

I have a problem with deploing my Vaadin project to tomcat7. I made an aplication which works in eclipse but when I export it to war file and I want to run it on my virtual tomcat, errors appear:
FAIL - Application at context path /nauka could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina]
.StandardHost[localhost]
.StandardContext
[/nauka]]

Below you can find my web.xml file.

<?xml version="1.0" encoding="UTF-8"?> nauka Servlet com.example.nauka.Servlet UI com.example.nauka.NaukaUI Servlet /* 30

AND ONE MORE ERROR FROM CATALINA LOGS:

Can you post the code of the NaukaUI.java file?

@SuppressWarnings(“serial”)
//@Theme(“nauka”)
public class NaukaUI extends UI {

GUI elements like tables and buttons
private Table haslaTable = new Table();
DataBase elements like
static SQLContainer temp = null;

…

@WebServlet(value = "/*", asyncSupported = true)
@VaadinServletConfiguration(productionMode = true, ui = NaukaUI.class)
public static class Servlet extends VaadinServlet {
}

@Override
protected void init(VaadinRequest request) {
setContent(layout);
initLoginForm();
layout.setMargin(true);
b3.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {
            insertNewUser();

        }
    });

    b5.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {
            deleteUser();
        }
    });

    b4.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {

            wprowadzZmiany();
        }
    });

    usunHaslo.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {
            deletePassword();
        }
    });

    dodajHaslo.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {
            insertNewPasswrod();
        }
    });

    zmienHaslo.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {

            zmianaHasla();

        }
    });

    zaloguj.addClickListener(new Button.ClickListener() {

        @Override
        public void buttonClick(ClickEvent event) {
            Logowanie();

        }

    });

}

Other methods like insertNewUser, deleteUser (from data base)

Your UI class shows that you have define a Servlet definition programatically, as well as using web.xml also.

The configuration in web.xml file override that of the UI class Servlet definition & configuration.
If yoy have some error in web.xml Tomcat woul have troble loading the web app.

[code]

<?xml version="1.0" encoding="UTF-8"?> [/code]The code above refers to web-app_2_5.xsd as well as web-app_3_0.xsd It may interfere with the normal web app deployment by Apcahe Tomcat. I would suggest that you remove the web.xml file entirely from the project, export the project again to create a new WAR, and then try deploying it again.

Thank You very much! It works :slight_smile:

You are welcome.

I had the same problem trying WAR-Deployment (production server)!
I compiled my project using 1.8.
So i’ve checked the installed jvm version at the server with “javac -version” or at the manager site of Tomcat (see bottom line).

Compiling and targeting to version 1.7 fixes the problem.
