Cannot run applet

[Webuser]

Oh, pa

I never even thought it is such a deep problem. But yummy I am interested much :D

As I was saying... It must be a test applet so provide us the problem piece of code plz.

OK... Later I'll publish the source files then :)

Eranga, did you succeed to download the jar as
http://www.findata.info/chart/jars/stock1.jar

cause I couldn't do this owing to my browser 404 :confused:

Of course I'm able to download it, using the above link. But it's not well configured as I post the content.

[Eranga]

@everybody
Hey guys just let me know you succeed to download the class.class file cause I've got 404 only :(
But I suppose it is a servlet... How you think?

I can download it successfully without a problem, and also I've extracted the content and check. I would say that I found few class files which are named in a nuts way, like a.class, b.class, c.class......

[Eranga]

Can't you find the source of it?

[Norm]

I've down loaded all the jar files and created a html file that will execute it. I changed the code= to be: code="ru.fmv.stock.ChartApplet"
I guess some browsers don't expect the .class extension. They must append .class to what is given on the code= attribute
The applet will load and executes but tries to connect to its codebase via a URL like:

C:\Temp\StockApplet\select_stock.php?key=1z2wqfsda &s=3315&r=1&sd=2008-07-31&t=1000&l=1000

And fails there

The data in the above is from:

<PARAM NAME="service" VALUE="select_stock.php">
<PARAM NAME="messageService" VALUE="select_message.php"
<PARAM NAME="key" VALUE="1z2wqfsda">

Emm... This one

C:\Temp\StockApplet\select_stock.php?key=1z2wqfsda &s=3315&r=1&sd=2008-07-31&t=1000&l=1000

Maybe it should be requested from the same host - the host the applet is from I guess not the local C:\Temp... etc
Perhaps that is the getCodeBase() problem :confused:

@Norm
Did you tried to sign it?

[Norm]

Did you tried to sign it

No. The problem is that the code uses getCodeBase() to build the URL.
Say String url = getCodeBase() + "select_stock.php?";
The URL: C:\Temp\StockApplet\select_stock.php?
has the path on my computer: C:\Temp\StockApplet\
followed by the file:select_stock.php that is supposed to be at the site where the applet was loaded from. In my case, the applet was loaded from my computer.

Pretty cool :)
So to make it work locally one should use a tricky thing :rolleyes:
Actually I thought that too... Watch my previous post.

Did you able to execute ChatApplet.class? I've tried but it fails.

[Norm]

but it fails

What do you see in the Java Console?
My version displays a GUI and then fails because there is no one to communicate with.
Here's what I get in the JC:

The IO thing

I think to make it work locally its inner code should be modified from getCodeBase() to an absolute one :) just like a

http://www.findata.info/chart/jars/S...&t=1000&l=1000

@Norm
Did you modified this and still has the error?

[Norm]

I don't have the source for this applet. I downloaded the html and jar files to test it and see what the problem was.

[Webuser]

@everybody

Strange ... I tried to run the applet http://www.findata.info/chart/select_stock1.html today but now I can see this errors list only. Different errors day after day? What you think?

java.lang.NullPointerException

PS I used IE 8...

[Norm]

I think this has been mostly a waste of time.
We're trying to debug a third party's code without their help or knowledge.

[Webuser]

@everybody

Hey, guys... Today I just remembered a thing like a the Java cache bug... So then I deleted all my TEMP files and started the applet and it runs fine :rolleyes:
watch it


The console shows only the outer resource ref...

http://www.findata.info/chart/select...&t=1000&l=1000

Perhaps the problem is somewhere in overloaded java cache :cool:

@Norm and @Eranga
Did you try to clean your Java cache before running it? Please, guys, let me know if that helps you too...

[Norm]

I just went to the site without doing anything with IE8 and it worked.
And also it worked with Chrome without my doing anything.

My conclusion is that the programmer fixed his site.

@Norm and @Eranga
Did you try to clean your Java cache before running it? Please, guys, let me know if that helps you too...

I'm not. I'll check with another download.

[Norm]

No, I have not cleared Java cache.

[gafa]

Wow, it works today! I've checked...

I must choose another host for this applet :(

Thank you all :)
