So I have a pretty basic Java app I have been writing in Eclipse.
I now have realized somewhat late that I want this to run as an applet on my website.
How do I setup JApplet? (assuming this is what I need to use)
Is there any "quick fixes" for assuring that the app will be able to be used as an applet?
This should get you started http://www.dreamincode.net/forums/topic/28410-application-to-japplet-and-reverse/
It was the first item in a Google Search, so next time look there first.

How do I combine a standalone Java application with an Android application?
I have a piece of code taken from the Google quick start examples that perform a task that I can't seem to be able to combine with my activity source code.
I'm of course talking about the following Google example: Sheet API, if I just add it as a standalone class and tell Android Studio to run this application, before my Android application, then it will produce what the code is suppose to do.
If I try to copy and paste the exact code into one of my activities it will give a couple of problems. One is that it can not find my keystore, another is a threading issue which I understand, another being that it can not find the credentials (even if the file is present), the newTrustedTransport-method call will be an issue, the setDataStoreFactory-method call will be an issue, file creation even with the correct uses-permissions and so on.
What is going on in the background that would make exactly the same source code work in one instance and not the other? What do I not know about Android Studio, and how an Android project works in the background for me having these issues?
I had an idea that I could just keep this standalone application as it is and store a file with the result that this Sheet example would provide me. But, since I do not have enough experience with Android Studio I have no idea if the result will be available for the actual Android application once it was made into a release. Will it? I can't save the output file generated by the Sheet example, under the res-folder, under the app module for some reason (scope?).
With other words... Can I have a standalone application, that is tasked to run before the Android application, to gather data and it will be doing this EACH time the Android application is run on a client? I feel like it would be stupid if the IDE would present this like this would actually work but then when the application is made into a release then the standalone application will not "follow" and be part of the release...
If I could just combine the source codes, I will not be having this issue at all. No examples online, neither Github or Youtube can provide me with answers on how to do this. Many examples online provide me with source code that is either out of date or just not what I'm looking for, and I really hate Google's way of explaining things. Just look at how they give code examples under this page: Google API Client Library for Java, and not give a full example where they would fit into the a project. Maybe all I need to make everything work is to use the code under "The library runs on Android 4.0 or higher (#Beta)."
I'm trying to find a developer to write a desktop program that has a pretty basic function. It will notify users, via some dialog (or alert) that some program is about to access the web cam. It could be skype or facetime, or whatever it is, the program should be aware of when the OS's camera is going to be accessed and notify the user. Yes, even if the user is initiating the camera themselves via Skype, the notification would still appear.
My question is this. If I need this program written in Java, is it possible? Obviously I am trying to get it done in Java so it would run on Windows and Mac.
If it is not possible, then it seems as though I'd have to write 2 separate programs on Windows and Mac.
I've come here to get suggestions so that I can connect with the right developers. If you have any suggestions, I'd be happy to hear them. Thanks!
No, you can't write this in Java. Whatever approach you take will be very system-specific (and will probably require enhanced privileges). You could write a JNI library and a Java interface, but it'd probably be about the same amount of trouble to write programs to the native UI libraries.
I am writing a minesweeper program in Netbeans, with java. I would like my friends to be able to try it, preferably on from there own computer, over the web. I have already made a .jar file, but do not know if how to proceed, or even if this is possible. How would I put it on the web so they can try it out?
Why not just send them the jar file? Then, they can just run it on their computer.
To put the program in a webpage, you need to put it in an applet, which will require some extra work (and maybe some changes to your code).

You need JavaWS (Java Web start )

One option is to write your game as an Applet.
See the standard tutorial or you can google for many others.
I created a small application that, when run, creates or updates some tables in a database by extracting data from some PDF files. Everything works fine in this desktop application, but the next step for me would be to make it possible for an administrator on a website to upload a PDF file and my Java program would then run and update the tables accordingly.
The problem is I have no idea where to start with this (the site isn't done yet, but I'm running some tests and it is going to be coded in PHP). I'd like to know what kind of technologies I need to let the server run the program and update everything as it would in the offline version. Sometimes it takes a while to update everything, so ideally, the user uploading the PDF could continue browsing other pages while the server does its job. (I'll probably implement something that when the server is done processing the file, it says if the program ended successfully or not in a log file)
Can someone tell me what terms to search for on Google or give me some pointers? I haven't chosen where my website is going to be hosted either, so if someone could tell me what to look for to know if they support running applications like this, I'd really appreciate it as well!
This could also apply to other programming languages as I know a bit of Python and C++ as well, so in the future I might have some applications in those languages I'll want to use on the web.
If I'm not approaching this the right way, I'm open to other suggestions, but the best solution would be to keep my Java program intact as I know it works exactly like I want it to and I'd rather not have to start it all over again.
If your host is *NIX based you can use crontab (Automatic Task Scheduler) to run your program at set intervals. Make it check if a "new" PDF exists, and run the program if there is. There may be a way to use Windows Task Scheduler type programs to do it on Windows. This is probably the easiest way.
Alternately you can use You can use shell_exec() in your php to execute a command on your *NIX system directly to run your java program.
Actually I am working on a java based application which has a functionality to turn off my system on a specific time and it's working fine but, the requirement says that if any application is open then it should not be close before turn off my system must have to close all the open application manually.
I am unable to find out the solution.
I have never tried this but it looks like you would have to use: Runtime.getRuntime().exec(). This seems to be a pretty good example of how to do this.
