This topic has been covered in one form or another but none of the other threads have been able to help. My issue is very similar to this post, I am making a JUNG graph with added functionality, but none of the solutions helped:
JApplet fails to run in HTML page
I had a Java application that I converted to a JApplet. The JApplet works fine in the applet viewer in Eclipse but will not work when I try to open it in a webpage (I have tried IE, FireFox, and Chrome). I have my HTML page and archive folder both in the same directory. When I load the HTML page it just brings up nothing.
Here is my html code:
<html>
<title>Applet</title>
<head>
</head>
<body>
<applet code="prerna.blueprint.main.BPTester.class"
archive="applet1.jar"
width="800" height="800">
</applet>
</body>
</html>
When I try to have code="BPTester.class" it gives java.lang.ClassNotFoundException: BPTester.class but when I use code="prerna.blueprint.main.BPTester.class" it gives me no errors just nothing happens. (prerna/blueprint/main/BPTester.class is the file path in my src folder). I exported my Java project as a runnable jar file, is this correct? I created a simple JApplet that worked fine when I did all the same steps but it won't work for BPTester.class.
If I need to post my BPTester.class code I can.
I don't understand why I can't view the JApplet in a webpage, any help is greatly appreciated.
What ended up working for me was adding every single jar I used in the japplet to the HTML archive tag then had to sign every jar. I then had an issue with accessing my database within the applet1.jar so I just put an absolute path for its location.
