404 page when run as web application project

I want to create a basic Google Web Application project and i get an 404 Page not found error.
I followed several tutorials and what i do is this:
Open eclipse - File - New - Other - Web Application Project (under Google) - name it - (it doesn't matter if i check "Use GWT" or not the result is the same - Finish.
Right now i have a newly created web application project, so i can test it in localhost. I right click it, run as - web application project (with google icon). After it finishes in my console i have this:
Mar 22, 2017 10:13:58 AM com.google.apphosting.utils.jetty.JettyLogger info

I open Chrome and go to localhost and i get:
HTTP ERROR: 404
Problem accessing /.
Reason:
NOT_FOUND
Powered by Jetty://
I must specify that i am deploying behind a proxy server. I tried also to run it without proxy, same result. All my settings are correct, because if i create a Dynamic Web Project and i deploy it on a Tomcat server, that one works fine.

The solution that worked for me is this. Check your Java facet. It has to be 1.7. Mine was 1.8.
Thank you.

Cannot run JAX-WS Java Web Service on Apache Tomcat

Summary
I've been tasked to write a Java web service to integrate two disparate systems in our enterprise environment. Since I'm actually an experienced C#.NET MVC developer and only consider myself intermediate at Java, I began by searching for "Java Web Service Tutorials". I am trying to run this common tutorial, but I'm unable to run the tutorial service due to an HTTP 404 error.
Process
I'm using the Java Web Application template in Netbeans 8.0.2. I used JDK 1.6.0.25 to compile the tutorial (since the eventual service I need to write will need this Java version to be compatible with some other JARs I'll be using). Everything compiles to a WAR file just fine.
I then deployed the WAR file by loading the server's Tomcat Manager GUI and using the WAR file to deploy feature. When I do so, the WAR file is copied, and the application starts. However, when I attempt to access the service via the link "http://localhost:8080/HelloWorld/hello" from the tutorial, the service returns a 404 error.
Server Environment
Oracle Enterprise Linux distro, version 3.8.13-44.1.1.el6uek.x86_64
Apache Tomcat 6.0.24
JVM 1.7.0_75-mockbuild_2015_01_20_16_42-b00
If the advice is that I need to change the Java or Tomcat versions or platforms, I need to know that as well since I have little experience with these technologies. However, I may not be able to change all the factors due to limitations with my Linux distro (per my server admin).
Things I've tried (in order):
Setup a Local Tomcat Server on Windows
I installed a local Tomcat Server on my Windows 7 laptop. Since the Linux server is running Java 1.7.0.75, I installed a matching Windows version of JRE 1.7.0.75 from Oracle's support page. I then downloaded Apache Tomcat 6.0.24 Windows Service from their archives and installed it successfully, using the JRE 1.7.0.75 and local port 1985 (to separate it from the GlassFish local server used within Netbeans).
Just as on the Linux server, my local Tomcat server couldn't start the tutorial. Manually clicking the start command link gives me the message "FAIL - Application at context path /com.mkyong.ws could not be started". My local server's logs don't show anything about that application failing to start either.
Adding JAX-WS RI JAR files to {$Tomcat}/lib
Per section 5 on the tutorial mentioned above, I then added the indicated JAR files to the server's {$Tomcat}/lib folder and restarted the server. This time, the application started, but I still couldn't access the service. The link "http://localhost:8080/HelloWorld/hello" from the tutorial returns a 404 error. I even tried copying the entire JAX-WS RI/lib folder to the {$Tomcat}/lib directory with no changes, so I backed out this change.
For reference, here's a list of the files I've copied:
gmbal-api-only.jar
ha-api.jar
jaxb-core.jar
jaxb-impl.jar
jaxws-api.jar
jaxws-rt.jar
management-api.jar
policy.jar
stax-ex.jar
streambuffer.jar
Enabling DEBUG mode in the local Tomcat Server
I un-deployed the WAR file. Using the Apache Tomcat Monitor, I stopped the service, deleted the existing logs, enabled the DEBUG logging level, and restarted the service. I then re-deployed the tutorial WAR file. I again saw it didn't start, and then I opened all the log files. There is not even a mention of the failure to access the service, but perhaps 404 errors aren't logged.
Running the service using the Netbeans-embedded Glassfish server
When I first created the Web Application, Netbeans offered to set me up with a local Glassfish server. I accepted, and I set everything up with defaults. When I try to run the tutorial against this server, I cannot access the service. The link "http://localhost:8080/HelloWorld/hello" from the tutorial still returns a 404 error.
Researching other posts and tutorials
Here are some other StackOverflow posts and websites I've reviewed without finding a resolution:
JAX-WS on Tomcat server (doesn't apply)
Deploying JAX-WS webservice as War in Apache Tomcat (similar to the tutorial in recommending to copy the extra JAR files)
JAX-RPC / JAX-WS runtime in Apache Tomcat (just informational)
how to deploy a jax-ws service to eclipse or tomcat? (similar to the tutorial in recommending to copy the extra JAR files)
https://myarch.com/create-jax-ws-service-in-5-minutes/ (similar to the tutorial but without deployment help)
Questions I'm Pondering
Is there something wrong with the code in the tutorial? (Doesn't seem likely since from the comments others have had success.)
Is there a significant difference in the versions of Java or Tomcat he's using in the tutorial? (He doesn't give an versions of Java or Tomcat.)
Should I run local Tomcat against a JDK instead of a JRE?
Should the tutorial be compiled against the same JDK as Tomcat is using? (I hope not as this would seem very limiting...)
Can I even run JAX-WS in Tomcat? (Based on pages like http://tomee.apache.org/apache-tomee.html, it seems like the base TOmcat might not even support JAX-WS? Again, just my limited experience.)
I'd appreciate any troubleshooting guidance anyone can offer. Thank you in advance for the help!
UPDATE #1
Per the request of #NIKETBHANDARY, I stopped the service, deleted the logs, restarted the service, and browsed in Chrome to localhost:1985/helloworld/hello - still getting the 404 error. I then opened the catalina.log file, but it's completely empty. Only jakarta_service.log has any log entries, and all are about the service starting. I also verified that the logging level is set to debug. What else can I change to get additional log messages?
I also ran a search for "com.mkyong" in the entire Tomcat directory. Only the webapp WAR file, webapps/../META-INF/context.xml, webapps/../WEB-INF/sun-jaxws.xml, and /conf/cataline/localhost/com.mkyong.we.xml files returned any hits. Nothing in any logs. Could that indicate that this is a configuration problem?
UPDATE #2
Apparently, Tomcat doesn't flush its log messages fully until the thread closes as the service shuts down (probably due to the logging configuration). As such, I stopped the service which flushed the log files. Here's the entire contents of the catalina.log file (which does contain a reference to com.mkyong):

UPDATE #3
I'm becoming more convinced there's a configuration problem somewhere. On a hunch, I studied and installed Apache TomEE 1.7.2 for Windows, pointing to the same JRE as the regular Tomcat. After studying the running.txt file and experimenting with the properties and settings, I was finally able launch a local version of TomEE. I deployed the same WAR file as before, and I found it would not load the WAR application due to the following error:
java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener
Googling that error led (again) to MKYong's blog for a fix (copy the jaxws-rt.jar file to the {$tomcat}/lib folder. I redeployed the WAR file, and the manager loaded the application. HOWEVER, just like on regular Tomcat, the URL "http://localhost:8080/HelloWorld/hello" from the tutorial still returns a 404 error. So, the results are exactly the same.
Short of compiling the tutorial against other versions of JDK, I'm running out of ideas quickly... :-)
UPDATE #4
Per another request below, here's a list of all JAR files in the {$Tomcat}\lib folder:
annotations-api.jar
catalina.jar
catalina-ant.jar
catalina-ha.jar
catalina-tribes.jar
el-api.jar
gmbal-api-only.jar
ha-api.jar
jasper.jar

streambuffer.jar
tomcat-coyote.jar
tomcat-dbcp.jar
tomcat-i18n-es.jar
tomcat-i18n-fr.jar

The {$Tomcat}\webapps folder contains the following:
..\com.mkyong.ws
..\docs
..\examples
..\host-manager
..\manager
..\ROOT
..\com.mkyong.ws.war
Update #5
The {$Tomcat}\webapps\com.mkyong.ws directory contains the following:
Here's a screenshot of the Tomcat Manager GUI:
Here's a screenshot of the HTTP 404 error I'm receiving along with the URL:
I've also confirmed that the files in the WAR exactly match the tutorial.

There is problem in deployment of your ws module.
U have just copied the whole folder from the MKyoung sample.
I doesn't work that way around.
Not only that now display all the folders and files structure inside the ws module delete the rest of the modules from your post.I wanted only the structure of ws module.
The module name has to sample instead of com.mkyoung.ws
and the structure for it has to be
**sample**
------WEB-INF
------index.jsp
WEB-INF
----classes
----web.xml
----sun-jaxws.xml
classes
----com
--------mkyoung
-----------ws
ws
-----Helloworld.class
-----HeloworldIMPL.class

#NIKETBHANDARY helped me understand what was wrong and how to quickly correct it. I'd also like to post exactly what I did wrong and how I fixed it permanently so that future coders can benefit from my five-day experience. :-)
When I originally built the tutorial using Netbeans, I used the Java Web --> Web Application template (which is available after installing the Java EE Base plugin accessible through Netbeans --> Tools --> Plugins):
I built all the files exactly per the tutorial, but I failed to really read through step #5, especially this line:
<jar jarfile="${dist}/war/HelloWorld-${DSTAMP}.war" basedir="${dist}/war/build/"/>
After further review, I found that the build script was producing a WAR file called HelloWorld.war. Then, when that file was deployed to Tomcat, the web application was called HelloWorld in the Tomcat Manager. That's why the service endpoint was set to http://localhost:8080/HelloWorld/hello. The "HelloWorld" is literally the name of the Tomcat application, and the "/hello" part corresponds with the endpoint from the sun-jaxws.xml file. (Looking back, it makes total sense given typical web hosting organization. IIS pretty much works the same way.)
So, to fix the problem, I needed to modify the Netbeans project to produce a WAR file named HelloWorld.war. In the tutorial, he includes an actual Ant build script. In this case, I needed to take these steps:
Right-click on the project in the Netbeans Project Explorer.
Choose Properties.
Click on the Build --> Packaging category.
Set the WAR file field to HelloWorld.war.
Here is a screenshot:
Once that was done, I created a new build, deployed to my local Tomcat server, and everything worked as expected. I was also able to deploy the WAR file to my Linux server and test it successfully. Problem solved! :-)

Tomcat is not shutting down

I am unable to shutdown tomcat. When I do ./shutdown.sh, I don't see any error, but the process still seems to be running. When I kill the process (kill -9), the process gets killed. After this, if I do a startup, and shutdown again, I see the same problem. How do I gracefully shut it down? Why is this happening in the first place? Please help me.

Something seems to be terribly messed up. I can't understand what. Please advise.
I am running tomcat 7.0.50 on Mac OS.

Judging by the logs, it is evident that tomcat is not starting up at all as it should be. I can advise a couple of other tests as well like to
Verify whether or not the ports are getting bound by the tomcat service or not. You can do this by issueing the command netstat -tuplen on the terminal and check to see if port 8080 is getting bound by the tomcat instance or not.
Check to see if you can ping the instance. Try to ping the tomcat instance from a local machine. Then try to ping the public ip of the server to verify whether that server is responding correctly or not
Verify that you have, infact, the complete tomcat template as is used by your other servers. Verify the tomcat installtion folder and compare it with the other tomcat templates as used in rest of your servers. Make sure all folders are there, all configuration (default tomcat config) files are present.
(Just a hunch) Verify read/write/execute privileges as well
Remove your application, shutdown tomcat, empty the logs, and then restart tomcat and re-deploy your application and then view the logs to see if you get some error
Point 3 seems more likely that you have an incomplete tomcat instance, so I advise you to make a copy of the tomcat instance used in any other server and use it in this server to make sure that the server environment is infact how it should be

Remote debugging on Tomcat with Eclipse

I'm trying to initiate a remote debugging session on my PC with Eclipse & Tomcat.
I managed to run tomcat (not through eclipse) with the following params:
set JPDA_TRANSPORT=dt_socket
set JPDA_ADDRESS=5050
cataline jpda start
The server starts ok, this is the outcome:
Using CATALINA_BASE: "C:\Java\Tomcat"
Using CATALINA_HOME: "C:\Java\Tomcat"
Using CATALINA_TMPDIR: "C:\Java\Tomcat\temp"
Using JRE_HOME: "C:\Java\jdk1.6.0_27"
Using CLASSPATH: ...
Listening for transport dt_socket at address: 5050
...
...
INFO: Server startup in 12502 ms
Now, I opened eclipse, and loaded the relevant project.
I set a new debugging configuration using Remote Java Application with localhost and the right port. however when I run it, I get this error message:
Failed to connect to remote VM. Connection refused.
Connection refused: connect
Can't really understand where is the problem. this is all local inside the PC, so there shouldn't be any firewalls involved, can someone think of something ?

Found the solution. apparently the connection was made, but Eclipse & Tomcat don'tt show any notification or status regarding it.
Then, when you initiate the connection again, you get the error because you're already connected.
I think that a small notice, either from Eclipse, or from Tomcat would be nice.

Try adding the following debug options directly to the JVM startup by directly modifying the catalina startup script
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5050

There could be problems when there are code mismatches between eclipse and tomcat. So when it matches the error will disappear

You can configure it in remote java application section in debug configuration.

Launching Jade In Ubuntu10.04 Linux

When I run the below command in terminal of ubuntu linux and also I set the ClassPath properly but I wasn't successful.
java jade.Boot -gui

INFO: JADE is closing down now.
help me to recover from this error.

I am so tired of this problem. It is one of many quirks and problems with JADE.
The problem you are facing is that you need to supply correct host information in the command line. Example
java jade.Boot -gui -local-host
This is all described here: http://jade.tilab.com/doc/tutorials/JADEAdmin/startJade.html
In many cases you don't have this problem and then it is sufficient to use the -gui option only. However I have discovered that Jade does not work very well when your resolves to 127.0.1.1. You can fix this by setting your IP address in or if you are on Linux edit your /etc/hosts file for a more permanent solution.

just type in JADE path..
java -cp lib/jade.jar jade.Boot -gui -local-host 127.0.0.1
(JADE has some problems to set local host adress)

The problem might be is previous java process might be still running on the local port , Make sure to check if port is in use or not if in use kill the java process before you rerun.

It's simple.
Modify /etc/hosts
Modify the line for the address 127.0.0.1, as follows:
127.0.0.1 localhost.localdomain localhost <machine_name>
Remove or comment the line with 127.0.1.1:
# 127.0.1.1 <machine_name>
and you're done.

The error isn't in the jade. It's a bug used by jade to start the default parameters with a bugged java method that should be fixed.
When jade runs the java method, it will retrieve 127.0.1.1 instead the loop-back 127.0.0.1.
I'm saying it because I tested. I read the JADE src that do this and I executed the java method that I didn't remember now.
Unfortunately it's happening in a few linux machines. In windows I didn't see it happens.
What I did to solve this problem was to edit the /etc/hosts file, like this:
Original file:
127.0.0.1 localhost
127.0.1.1 machine-name
Modified file:
127.0.0.1 localhost machine-name
127.0.1.1 machine-name
What I did was to put an alias of the machine-name on the loop-back ip address. This will bypass the bug.
