I have designed a google web application using Eclipse and the Google GWT plugin.
Is there some way I can see the GUI of my application on iPhone or iPad.
Please, give me suggestions or tell me if it is possible.
You are referring to a company server (IP 10.24.56.34). If that is a web server that you or someone from your company can administer, then follow the below process:
In eclipse select your project, right click on it, go to google
option and select GWT compile.
At the pop-up press compile.
Wait some time (can be a lot, if your project is big/complex).
After compilation has finished successfully, go to your workspace
using an filesystem explorer utility (Note: Right click your project in
Eclipse, select project properties, select resource to find your
project's location on disk, if you have any doubt as to where it is
located.
Inside project's directory, you should find a war directory. Copy all its contents
in a suitable directory for your webserver to be able to publish.
Hit the werbserver's IP and the publish location you used at the previous step, appending the name of the only HTML file you will find in the above mentioned war directory. You should be able to see your application. Of course you can browse this location from a browser from your PC to make sure you do not have iPhone related issues.
Hope this helps you!
If you have a Mac you can install Xcode and then see it in the simulator by typing in the localhost URL. That should give a pretty good indication of how it will look.
You may also be able to make your computer visible on the local wi-fi network by enabling web sharing and then just access it by IP address from the iPhone browser.
Alternatively, if you set up your computer as an adhoc wireless network, you can connect to it from your iPhone (select your computer as the wi-fi router) and again access it from the iPhone browser using its IP address.
In debug mode you'll have to use -bindAddress and use an address that you can access from your phone. If you have a local wireless that both your compter and iphone can connect to then using -bindAddress 0.0.0.0 will bind to your wireless card IP address (so you don't have to type it). On my laptop it looks like this:
Dev Mode initialized. Startup URL:
http://192.168.1.100:8888/index.html?gwt.codesvr=192.168.1.100:9997
then just open this address in iPhone.

I just made a simple web application (using java and jersey as i want to start making a rest endpoint). I am working on intelliJ idea
I used this tutorial to build it.
I gave the project a name, group id and artifact.
Now when i run it in my local tomcat server, it runs successfully but does not show me the name of my web application in URL. It only shows localhost:8080 as can be seen in the screen shot below.
Why is it displayed like that? How can i give my application a name/URL?
Basically, you need to watch this video first: Domains and the Domain Name System and then fully understand what the following paragraph means. Then your question will solve itself. Good luck! :D
localhost is the IP address of the server where the tomcat (which is an application server) is running. 8080 is the port. The localhost maps (from Windows hosts file) to 127.0.0.1 and this is a loopback IP address (meaning that it is, in fact, yourself).
p.s. that's what about the name in the URL. About the actual browser tab name, it's the <title> HTML tag.
How can i give my application a name/URL?
You need to buy a domain name.
So what i was looking for was to set the application context in tomcat server.
Here is how i did it: On IntelliJ idea, clicked on 'Edit configuration' -> than on 'Deployment' tab.
There is an option for "application context' there. I give it the name of my application(or any name that i like) and click 'apply' and restarted the server.
Here is how it appears in the browser now:
I am working in my final year project and I created a web service in a dynamic web project using eclipse JEE, tomcat 8.5 and Axis 2 ( all this is running in Ubuntu 16). this web servicie calls some programs that are installed on a computer ( Matlab for instance) so I need this computer to host the Web Service. This web service works fine in local host ( I created a client to check it) now I need to do the next step. how can I deploy this web service on internet? ( NO localhost), There is any tutorial or documentation to do something like this? The computer where I am working is of my university so it is connected to the university network.
I have read that I need a WAR file, I know that if I right click my project and the select export it says "WAR file", this war is going to have all the references and .jar that I added ? ( I am afraid of this because I neeeded to add some .jar and also some native library locations to them) Also I know that I need to have a Statc IP instead of a dynamic one. how can I achieve it if I have no access to the university routers?
Thanks for your help.
If you want your own domain, then you will have to buy a domain if you want to be on internet. There are website like GoDaddy or BigRock, that provide domains.
If you are doing it for testing or demonstration purpose, you can use NGROK tool. This tool will provide a domain over internet (something like http://.ngrok.io), that will be mapped to your localhost. The domain can be customized if you are using paid version.
ngrok.exe http 8080
OR
ngrok.exe start -config="config.yml" config-name
config.yml
http_proxy: ""
log: ngrok.log
tunnels:
config-name:
proto: http
addr: 8080
As you stated you need a "computer to host the Web Service" on internet, as you also have the constrain to use specific libraries so you cannot use a "ready-to-host"(paas) solution like heroku because you wouldn't have access/control to the computer hosting your webapp. The only solution I know to deal with that is VPS hosting (https://www.ovh.com/us/vps/) with that you can "rent" a remote computer (with ubuntu 16 if you want) and have total control on it for example you can install whatever native library you want on it, and also any servlet container/web server you want like you would on your local computer.
But then your web service will be on internet, which is "outside" the university network, if you need to access some data/services only accessible from the university network, you cannot use this solution unless you have a special (and secured) access to connect the university network via VPN for example but you'd have to ask to your university if something exists in the university network to allow traffic coming from internet (which I suppose is not the case...but you can still ask to the IT department of the university). Anyway, what you want to do cannot be achieved the "easy-way", lot of work foreseen to have something like this working. If it's a university project, maybe it should stay inside the university network.
I have created a website running on eclipse and tomcat. What is the way to make this website running online for real?? I have developed it, adding filters and sessions and using a database. I want to allow people to use this website. What I have to do?
You need to publically expose your computer and the port you set up.
If your application runs locally, it must be able to be hit by the outside world.
Make sure the tomcat config is setup correctly and ensure port forwarding on your router or modem is setup. Your public IP (available if you google whats my ip) and the port is all your users would need.
So I just got internship at this company, and they would like me to complete a project(Web application) which someone else did but didn't finish two years ago. But the person didn't leave any documentation about this web app. Right now I would like to run and test this web app, but I couldn't get it started.
So it's running on WebSphere Application Server in IBM Rational Application Developer, the code is written in java and javascript. (I could start the server, but I don't know where to go and open up the web app)
Sorry I'm really new to this, questions might be stupid, appreciate any help:)
Do you know what port it's running on? You should be able to access it from a web browser on the host machine by going to
http://127.0.0.1:XX
where XX is the port in question. If you don't know, try 80 - that's the default HTTP port and it's worth a shot.
The default websphere web port is 9080, so try http://localhost:9080/
So it's running on WebSphere Application Server in IBM Rational Application Developer
and
I could start the server
Assuming you are able to start the server via RAD as I assume from the above and you are able to publish the app to WebSphere via RAD, you should then be able to right click on the project folder and choose "Run on Server." It will walk you through publishing the app to the server and will then launch a browser to the index page or URL via the context path and web project settings. You can have RAD use an embedded browser (default) or adjust it to launch an external browser via Preferences -> Web Browser.
To manually check where a webapp will be deployed you can either check application.xml (if you have one) OR you can right click on the project root folder in RAD, choose Properties, and Web Project Settings. The context path is in a field there.
Run-On-Server will show you both server/hostname (usually localhost), port, and application context path in one operation.
I am learning Java and am trying to do some experiments with networking Java programs.
I have a program made in 2 parts with a client and a server and it works in local testing but the program actually has usefulness for me and a friend of mine and I want to put the server online so both of us can connect to it and use it.
Where/How can I put the program online and have it running so that the client programs can connect to the ServerSocket with an ip address? (Preferably free)
If you dont want to pay server hosting then I would open a virtual server on my computer, then playaround with modem and forward related port to server ip. I would use a port more than 40000. Then just send your ip and port your friend or update application.
If you really want the application to go live within 5 mins, try Jelastic. If you have built a WAR file, simply sign up with their server,choose a provider closest to your geo location, configure Tomcat and you can upload the WAR file through their fantastic web console. Otherwise if you have some source control system(SVN,GIT etc), you just connect and build it with their Maven console and you can be ready. I used it for my start up(Cloudlabz) and really found it exciting.

You could also consider the cheapest Rackspace Cloud Server. You'll get a full fledged Linux server (distribution of your choice) for about USD 11/month. I've done that now and then myself to try things out.
Just install Java on it and you're good to go.
http://www.rackspace.com/cloud/cloud_hosting_products/servers/pricing/
http://ideone.com/
is that what you want for this?
This is a free web app for you to run your program online....so you can just paste your code and run it.
On the cloud you could use two different services in order to host your Java application.
IaaS (Infrastructure as a Service). Where you can just rent a specific infrastructure on the cloud and you could install and configure all the services that you need.
PaaS (Platform as a Service). In this case, you still enjoy the infrastructure on the cloud + the service Aaren full pre-configured. It means that you can deploy your application without installing or configuring anything. You just need to deploy your application. You have an example about how it works here. Also, you usually can test your Java apps on the cloud without paying.
You should host the server in Heroku ,they offer a free hosting with limits , I have an app there
