Applet works locally; not on server

[tonyb48]

I found a free applet that puts a changing message on my web site. It works fine on my hard disk. After uploading it to my website, all I get is a gray rectangle with a coffee cup. Any suggestions how to debug?
Thanks

See what it says on the Java Console. If using Internet Explorer Click Tools -> Sun Java Console.

Thanks for such a quick reply. I don't know how much of the Java console report will help. Here are the first main entries:

Java(TM) Plug-in: Version 1.4.2
Using JRE version 1.4.2 Java HotSpot(TM) Client VM
User home directory = C:\Documents and Settings\Tony

Proxy Configuration: Browser Proxy Configuration

----------------------------------------------------
load: class mpanel2.class not found.

java.lang.ClassNotFoundException: mpanel2.class

at sun.applet.AppletClassLoader.findClass(Unknown Source)

...

Caused by: java.io.IOException: open HTTP connection failed.

at sun.applet.AppletClassLoader.getBytes(Unknown Source)

... 10 more

Similar messages show up whether I use Mozilla or IE 6.


Since it said "not found" I checked with WSFTP and found the applet mpanel2.class in the same directory as the web page on the server, like it said in the instructions.

Any suggestions what I should look at next.

Thank you very much.

Please post the HTML you're using i.e. the <applet> .... </applet> tags. Also, where did you get this applet?

[tonyb48]

Wow; you are really quick. I really appreciate your help. Here is what resides in my applet tags. I found it on javafile.com.

OK...that all seems fine...can you please post the following:

1. The address of the website where you've uploaded this applet to.

2. The specific adress of in javafile.com where you downloaded this file.

[tonyb48]

Well the actual website is for a class I am taking. The site is:
165.196.161.114/barr5312/hw6/scheduled.html.
Being on a school server and all this requires a user name and password which are:
flc-instr\barr5312
437-2671
Here you will observe the phenomenon about which we have been talking. However, in trying to provide an alternative view I just now installed the applet at:
www.tonybarre.com/brandt/scheduled.html. It works fine there! So I wonder if my school server requires something special? As you requested, the applet was downloaded from
http://www.javafile.com/bannerutil/m...nner+Utilities

Your support is awesome! Again I thank you.

Tony

hmmm....all very strange...I'm not sure all about this, but is the server where it isn't working Linux? If so, just check that the file access privileges on the class file are set so that the file can be read.

[tonyb48]

Well, it may be time to just close this one out. My instructor agreed to look at the page on my hosting service instead of on the school server. There is no problem there.

In attempting to follow your suggestion I tried CHMOD in WSFTPLE. I got the following response:"chmod 777 mpanel2.class command not understood. CHMOD failed. It may not be supported on remote site.

Thank you very much for all your effort on this. I am very grateful.
