currently we are developing a JAVA APP that runs on TOMCAT and uses POSTGREE SQL
And we have an introducting website (JOOMLA 2.5 based) that explains the app, and also have a register module, that runs on APACHE PHP, on a different server.
Our goal is that the clients enter direct to our website JOOMLA, register there and then they can go directly to the web-app.
Very like to www.tiendanube.com or shopify.
The java-app has a login as well as the joomla website.. We need to unify those process, we cannot find a form to achieve this.
The problem is also that Joomla cannot run in the same server as the web-app.
Is there any way to interconnect both the web-page and the app (which runs in differents server) to make then look as one ?
So we thinked that when the user register in the joomla it also has to be saved in the same POSTGREE SQL of the java app. Since the java app is running in a different server we cannot access postgree SQL of the java app
That can be a solution, still we are pretty sure it has to be a easy solution or a more powerful and better solution for this.
Also been the 2 services in differents servers, it seems that we are not able to mantain the same domain for both.
We will really appreciate some help
Thanks very much

You have at least two ways to do it.
Use a LDAP, GMail authentication or equivalent. Easy, Joomla already have it
Do in a manual way with "Single Sign On across multiple domains". Will have to undestand how session cookies works and avoid avoid some problens.
Please read my recent answer on implementing SSO across subdomains in joomla

I want to make a website done in Java language. This is for my own learning purpose. Since I am doing things myself I tend to get confused.
If there is a Login Form wherein a huge number of people all around the world need to feed their login details and that data gets stored.
To achieve this, do we need to have a database hosting?
Can you please guide the exact steps for this?
I know Core Java and MySql Database Basic knowledge but I have not done both app connection procedure.
I only know to code in Java and SQL queries. I had done an earlier basic application that runs only on a system (This was done in VB.NET and MySQL).I did this a decade back. Now that I am back to programming after a decade, I am bit confused about how to make this connection in a way that the Login form stores the details from the website to the database. The database should be MySql or some data hosting site? I will be trying this out on Windows System in Eclipse Neon. Let me know if you need further details.
Now that you are well versed with Java and MySQL, you can learn about Apache Tomcat and Struts 2.
With these, you can make an application that serves your purpose.
At the front-end, you'll have jsps with the login form.
With struts, you can map actions (like button clicks) to java classes. In these Java classes, in the backend, you'll have the code to connect to DB and store data.
Hope this guides you make your web application. :)
You don't need a database hosting but you need a database server configured properly at your system for localhost development.There are many sites guiding you to make a full java app using jdbc and jsp step by step you can get there easily.They will guide you to configure your database server.
I just need a little hint in what direction my research should go.
Because currently I have a spring standalone jar project (spring-context, spring-data-jpa and hibernate entitymanager. Everything set up without xml files).
Now I want to run this application on two computers inside a network. Both should be able to send objects over the network. But I want to accomplish this without a web server (so no tomcat or glassfish).
Is this even possible? and how is this called?
I have problems finding something close to this plan. Most of the time I find tutorials and threads for sending objects with tomcat. But I more or less only need a open port that listens to incomming objects.
EDIT
Later I also want to put a third player in the communication process: A website. So then two standalone jar programs and one website will pass objects around. That's why I hope spring mvc will work for a stanalone solution as well.
(I know that this question will get tagged down, but it's ok, as long as I get some designations I can use to research better, so thanks ...)
You have many specifications. ProtoBuf seems to be interesting https://github.com/google/protobuf/tree/master/java
Without having server it would be a pain for you as you will have to implement concurrency, security and this kind of stuff.
Does Spring Boot work for you? Server is embeded ;-)
What about use normal java sockets? There is plenty information if you google it. If you need help with this just let me know and I can send you some java application. Just type Java Sockets and lets learn!

I'm making a voting app in Java using Eclipse where the user votes for their favorite team. Right now I have a local MySQLite database that I am managing with the MySQLite Firefox extension. The votes are stored in the MySQLite database, then I have another java application that reads from the database and outputs the name of the team that got more votes. However, I would like to store this database online, so multiple people can vote at once, then the results are displayed. How can I go about doing this? I am guessing that I will need PHP, but I am having a hard time finding a tutorial on how to integrate a MySQLite database with PHP. I pretty much just need to store my database online. Everything is functional locally.
Maybe I'll need more details but I'm assuming you have wrote a Standalone Java app, which is connected to you local SQLite Database.
Also, I think you don't want to distribute that app for everyone who wants to vote (would be better if they could vote via a website, right?).
In this case, you have to write a web application to provide both front-end and back-end of your app. You can pick one among many existing languages and frameworks (PHP is one of them), such as Java itself with some web framework, Ruby on Rails or Python/Django (just to depict some of them). Plus, I'd recommend you to use some other database such as MySQL or PostgreSQL.
Here are basic tutorials to you follow for some of the previously mentioned languages/framework:
Java (JSP)
PHP
Ruby on Rails
To deploy you app (i.e. put it online, you'll need a server). Honestly I'd recommend you to use Heroku because the deploy process is really simple (just push your code using git) and you can run your app for free (if your app got really successful you may have to scale up the server and then you'll have to pay, but maybe that's not the case, right?).
So, pick up a language and framework, write your web app and deploy it to the server. Then you can have multiple access voting into the same database.
I need some advice. I'm new to Java EE technologies. Anyway, I would like to make my first JAVA EE project.
Imagine 2 client applications and server application.
1) Server. I picked up Google App Enginge technology to create server application. I would like to connect it to some easy database.
2) Client applications. I would like them to be desktop applications (or applications launched from the desktop) and these 2 apps also have to be connected to the same database as sever.
There was no problem to create this in Java SE environment - I had two clients applications with sockets staff and server application with socket staff. All worked locally.
But now I want to have server and database on the Internet and I want to make it in more professional way.
My problems are:
How to create free database from GAE? Is datastore the best option or something else? What's important - the client desktop application will also use this database. I'm looking for the easiest solution.
Maybe the solution is to create web client application instead of the desktop one - but make it look like it was desktop app (I would like to avoid using browser). I have no idea how to do this and if this is even possible.
Any help will be really appreciated. I'm stuck because my knowledge is too little to start. I have ma GAE app and I don't know what should I choose next.
Thank you in advance.
If you want make desktop application, you need to build backend application first.
check this out. You can use same concept with that. Build back end, and then create API to connect to your backend, and use that API in your desktop application.
Datastore is easiest way to store data. Check this out. Datastore have some limitation (such as didnt support join, many to many relationship, etc). Please consider wisely. Otherwise you can use Google Cloud SQL for your option, but AFAIK its not free.
I want to write an application that runs entirely locally on one machine - there is no need for connection to the internet or to any external machines.
I was thinking that it would be a good idea to use a web browser as the platform for this application so that I would not have to mess around with lots of UI stuff - I could just knock together the web pages fairly quickly and take advantage of CSS to get consistent styles throughout the application.
However I want to interact with a MYSQL database on the machine in question. With this in mind I was thinking that I could somehow use Java to process the information that the user inputs from the application and communicate it to the database via JDBC.
I know that I could use an applet to do this but the downside to that is that I would like the user to be able to save files to the local machine - and I have read that applets run in a sandbox which prevents them from gaining any access to the local machine.
I also know that I could use PHP but I would like to take advantage of object oriented design which Java is perfect for.
Does anyone have any thoughts, suggestions or links to tutorials/webpages which could help me to decide how best to go about this.
Any thoughts are very much appreciated..
I know you said you don't want to mess around with GUI stuff in java, but have you looked in to java web start? It does almost exactly what you need; a user clicks a link through a web browser and your application is deployed on their machine, it even checks to make sure the right JVM is used. Because it is a full application and not an applet, your app won't be sandboxed, and you don't have any access restrictions in your program (other than the normal java stuff..), and for example, it would be easy to do what you mentioned and talk to a mySQL DB. The only downside, is what I mentioned earlier, is that you would have to design a UI in java.
Web Start Wikipedia Page
Sun FAQ on Web Start
Grails may be a useful starting point. It'll provide you with a web server solution that's standalone, and it'll look after the JDBC requirements and the CRUD (create-read-update-delete) capability via dynamically generated web pages. It should take minimal effort to put together an app providing your database interfacing via web pages.
(fyi. Grails is the Java equivalent of Rails)
If you feel comfortable with Java EE-based web development, you could probably just bundle your application with Tomcat or Jetty.
If you do not want to run standalone servlet container just for one application, you can also embed Jetty into a runnable Java application (see documentation here).
Either way you can leverage existing Java EE frameworks (Spring JDBC, Hibernate, all those web frameworks) for abstracting away technical complexities, although with embedded Jetty, you'd probably need to write some kind of integration layer for the web application framework of your choice.
I think you should give Restlet, a lightweight rest framework a try. The tutorial shows you how to start a local webserver, and by that deliver a "Hello World" through the browser within minutes (no joke!), and there's plenty of extensions for any kind of need.
In combination with Java Web Start by which you can deploy and start the application to the local host this should be what you need.
as someone suggested already you can use embbeded jetty server on your application and just let your user to start it using somekind of shell script or batch script. You only need to make your layour directory complaint with a Java Web Application and your on it. ie:
MyApplication
app/
WEB-INF/
lib/
classes/
web.xml
start.bat |
start.cmd - depends on your client OS
start.sh |
Then you should only need to take care of launching Jetty in your start.[bat|cmd|sh] with your app as your webaplication context and your done!
Using JDBC doesn't mean that you have to write an applet, you can use JDBC in any kind of application: a desktop application, a web application, EJBs, MDBs, etc.
You want to use a browser and Java on the server side? Then go for it and use Servlets / JSPs. Consider maybe using an presentation framework (Wicket, Struts2, Spring MVC,...), Hibernate for data access and Spring for other facilities and wiring. Grails is a good idea too.
BTW, I'm not a PHP specialist but PHP has object-oriented capabilities (introduced in PHP4 , enhanced in PHP5) so you won't sacrifice everything if you choose PHP.
So it really depends of what you want to do. If you want to write some Java (webapp or desktop app): choose Java. If you want to put quickly a few web pages in place and have an apache server, choose PHP. If you look for really high productivity, go for RoR or Grails.
You can try GWT + Google Gears
GWT is a GUI toolkit similar to Swing for the browser. Google Gears is a browser side database. Your app is completely in Javascript in a single HTML file and cross-browser compatible.
GWT app can make Server calls and Gears can sync up with a Server database. So you need not restrict your app data completely to the local desktop.
If you're interested in some experimentation, like new stuff and would like to reuse the plethora of Java libs (including JDBC) then you might be interested in the lift web framework, which is Scala-based.
If you want to do it as an applet you can. Sign the applet and give it permissions to the local network (to connect to the MYSQL server that way)... that should be possible. Here is a tutorial on it.
