Recently, I had came across an open source a Java applet. I wanted to know is there somehow I could create a script that could be distributed and the applet could be embedded in any website?
I have been able to inject JQuery and JS scripts into websites by placing a <script> tag pointing to a Javascript file and placing it in the header of the page but I don't know how a java applet can be injected.
You can take a look at corresponding tutorial page: http://download.oracle.com/javase/tutorial/deployment/applet/deployingApplet.html
General steps are the following:
Build applet JAR file
Create a JNLP file, which describes your applet
Create web page, which includes script, which starts applet
Deploy all these artifacts on some web server

How to make images slider (carousel) in Java Spring MVC.
I have admin panel which upload the images to local drive.
I would like to display images from local drive to JSP page in carousel.
Please guide.
Also I tried one example from the link https://blog.e-zest.com/dynamic-carousel-built-using-javascript/ but I am getting javascript error.
Thanks,
Bhavin
First you need to be able to serve your files to web browser. You can serve files from local drive using tomcat or web server (nginx, Apache httpd etc) built-in features without writing Java code or write a Spring controller to read files form drive and serve them if you need custom logic.
Then you could use one of javascript carousel plugins like Slick or another - there is a great choice of those.
Add needed scripts and css to your page and follow selected plugin instructions to create needed HTML with your JSP page.
I've coded a game in Eclipse (still working on it), is it possible to run it's jar file in browser so that anyone can play right from their browsers instead of downloading jar file?
I.e I upload it on my website so that anyone can play right from the link I provide them.
Consider using Java Web Start with JNLP. You can host a JNLP file on a web server somewhere, along with your jar, and users can use a desktop shortcut pointing to the link, or a browser to open your app. (Using a browser will require having a web page with an applet tag: the article mentions how to do this but doesn't separate the two.)
I'm having a lot of difficulty getting an applet I made to run in a web browser. Java security keeps blocking it. I have the jar sitting on my desktop and I made a simple html file that embeds the jar using . I'm trying to embed this in html for my website. I don't have any root access to the site at all so I want to avoid using Web Start and Apache Tom Cat stuff because it seems those tutorials assume you're uploading the app itself to the directory of the site itself. I can only embed html here, so I have a jar located in my googledrive.com/host that I'm trying to link.
Here's the code for the tag.
<applet
codebase="https://bb2f18b1cb19b925c50b747c1c65afcc4ad11720.googledrive.com/host/0B34NA0csYJZufm5ZeFFEcUMyQnR5bmw1eVl2M3BOcXItNGxxZTZvaFExNVhXQnY4dzY3QTg"
archive="AsteroidGameApp.jar"
code="asteroidgame.AsteroidGame.class"
width=500
height=500>
</applet>
I don't even know if it would run correctly or not because I can't get past the security. I've read stuff about getting the code signed but I can't find a clear tutorial how to do that.
As reported on the Java related site Starting with Java 7 Update 51, trying to run unsigned Java applications generates error messages and prevents executing the applet.
Follow the instructions about the Oracle proper solution (I my experience I had to get a valid certificate from a trusted root like Verisign and then used this certificate to sign my applet jar) but if you can't do this way, try the suggested workaround in the correspondent section.
Obviously, as stated by the Java site:
It is highly recommended not to run these types of applications. However if you still want to run these apps, run only if you understand the risks and implications.
I've downloaded the google plugin for eclipse, along with the necessary app engine stuff. Now the question is, is it possible to host a pre-made applet using google app engine, and if so, how?
An applet is just a jar or a series of jars that must be downloaded by the browser. Put the jar(s) in your web archive just as you would put a HTML, CSS, image or JS file, and include the markup for the applet in the appropriate page.

Taken from In Eclipse Plug-in, how to launch a web url using system broswer?
Assuming you have a file to open.
You should read Runtime it allows you to execute a launch of a program (your default browser for instance.
With Java, your website is dynamic, so you need a server to run your web application. The most common one is Apache Tomcat. You should read about Tomcat if you plan to program websites with Java.
