What's wrong with my applet?

**phu004** · 11-20-2012, 11:28 PM

Hi guys,

I have an applet stored on a free web hosting website. The problem is, when you try to load it, it pauses for like 30 seconds before the the applet starts. I am not sure what is is doing during that period, it doesn't seem to be running any java code based on the java console output or downloading any applet files since the pause happens after the java download splash sceen.

Any one would like to help me debug this weird behavior please take a look at my applet at [Moderator edit: link removed]

Thanks in advance.
Pan

P.S I just hosted the same applet on my local machine ( [Moderator edit: link removed] ) , and it doesn't have the pause at all.

Please go through the Forum Rules -- particularly the third paragraph.

I wasn't trying to put an advertisement here. It's just an easier way to show others the issue i was talking about.

Seeing the issue without any knowledge of the code doesn't facilitate understanding the possible cause. To get better help sooner, post a SSCCE (Short, Self Contained, Correct (Compilable), Example) that demonstrates the problem.

My applet uses 2 files, a jar file (2.2MB) which contains all the class files and some resource files; a simple html file which tells the browser to load the jar file. The 2 files were uploaded to the same folder on the website server.

The problem is when I run the applet by visiting the html file on the website server, the applet didn't start until around 30 seconds after the java applet loading screen. No error message in the java console,

I am sure during that 30 seconds:
1. it's not running any java code. Because I included a print statement in the first line of init() method, and I didn't see any printout message on the console during that period.
2. It's not downloading the jar file, because the pause was after the java applet loading screen.

my html file contains the following:

XML Code:

<html>
<body>
<center>
<applet code=main.class codebase="." archive="church.jar" width="640" height="480" >
</applet>
</center>
</body>
</html>

Any suggestion on this weird behavior is much appreciated!

If a jar contains several classes you should have a manifest.txt file inside the jar with the line

Main-Class: ClassNameWithEntryPoint

and the name of the class (without extension .class) that should be used as entry point. I suppose you couldn't see you print statements because the init() was never started. If you start the applet inside the browser and inside the applet you invoke System.out.println() the output is send to the java.Console. To see the java console go to Internet Options -> Advanced -> Section Java and then check the Show Java Console. Close the browser and restart it again. You can also start your applet locally with:

appletviewer yourhtml.html

In this case the output is send to your os-console.

About your performace problem I can't tell you nothing, bacause the problem could be the network or the server or something else.

That isn't needed for a jar'ed Applet. The HTML tag identifies the class to be launched.
