Hello Lily, The error message informs you that the browser can not find the .jar-file file with the applet. The following string Code:iu.javaAppletCodeBase ="./"
means that the file has to be in the same folder where the page with Image Uploader is situated. As I understand your page is not situated in the root folder so that is a reason of the problem. Relocate the file or change the iu.javaAppletCodeBase field value to the appropriate path. Edited by user Tuesday, February 19, 2008 4:25:18 PM(UTC)

My page looks like this: Code://For ActiveX control full path to CAB file (including file name) should be specified.
iu.activeXControlCodeBase = "../ImageUploader/ImageUploader4.cab";
iu.activeXControlVersion = "4,0,47,0";
//For Java applet only path to directory with JAR files should be specified (without file name).
iu.javaAppletCodeBase = "../ImageUploader/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "2.0.50.0";
And since the activeX control works but not the Applet (in Forefox), the path shouldn't be the problem. I'm using the trial version by the way. The catalog/file structure is as follows: ~/ImageUploader/ImageUploader4.cab ~/ImageUploader/ImageUploader2.jar ~/ImageUploader/iuembed.js ~/ImageUploader/Resources/[language.js files] ~/defaultWithFrames.aspx ~/theFrameWithTheControl.aspx ~/Webfunctions/theControlWithImageUploader.ascx So, can the problem have somthing to do with using frames and javascript? Or with the fact that the ImageUploader is in a control. Please help, because I really think this would be a create product for my site if I get it to work.

I managed to get it to work when I used iu.javaAppletCodeBase = "./";
So the path should be relative to the iuembed.js file for java applet and relative to the page for ActiveX???? If soo, you should tell that in your comentaries.
Please still answer me, even though I think I have solved it. It could be that for some other browsers, it still doesn't work.
Sincerely
Patrik Fischer

Hello, While trying to reproduce your problem, I checked that the following code works right with a similar file/catalog structure, i.e. path in iu.javaAppletCodeBase is relative to page, but not to iuembed.js. Here is my test code: Code:<script language="javascript" src="../scripts/base/iuembed.js"></script>
...
//For ActiveX control full path to CAB file (including file name) should be specified.
iu.activeXControlCodeBase = "../ImageUploader/ImageUploader4.cab";
iu.activeXControlVersion = "4,0,47,0";
//For Java applet only path to directory with JAR files should be specified (without file name).
iu.javaAppletCodeBase = "../ImageUploader/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "2.0.50.0";
and file structure: ~/ImageUploader/ImageUploader2.jar ~/ImageUploader/ImageUploader4.cab ~/scripts/base/iuembed.js ~/WebFunctions/PageWithImageUploader.aspx Edited by user Monday, February 25, 2008 6:24:56 PM(UTC)

Hi Jin
Thanks for helping me out.
And did you test the javaVersion? with Firefox? Because the ActiveX works just fine. I find it weird I should have different paths even though the .jar and .cab is in the same folder. And it really solved the problem to change the path (javaAppletCodeBase).
Sincerely
Patrik Fischer

Hello Patrik, Yes, I tested it with Firefox 1.5.0.7. Just in case, try to clear Mozilla's cache (Tools->Clear private data) to be sure that no cached pages are used. Also I tried to set incorrect path in javaAppletCodeBase and behavior was expected - classNotFound exception occurred. And what do you mean by 'ActiveX works just fine'? After installing ActiveX control OCX file remains in IE cache, and later, when you load some page with this control cached OCX file is used, but not CAB. I suppose, if you delete Image Uploader from IE AddOn manager it will not be installed through your page. Edited by user Monday, February 25, 2008 6:25:11 PM(UTC)

Clearing the cash didn't do it. And when I changed back to "../ImageUploader/" from "./" it stopped working again.
With ActiveX I ment that it has worked with "../ImageUploader/...cab" since the beginning.

I tried it from another computer, that couldn't have any cash, and that solved some of the weird things. The "./" for applet didn't work, and really shouldn't. Only ./ImageUploader/" worked.
Remember the catalog structure:
/page.aspx
/Webfunctions/Control.ascx
/ImageUploader/[.js, .jar, .cab]
Since the page is in the root, even though the control is in /Webfunctions/, the path should be "./ImageUploader/" for both ActiveX and javaApplet. And this work WEEHOO!
BUT, ActiveX did actually work with "../ImageUploader/" too. That's a little weird.
Sincerealy

Are you sure that ActiveX version wasn't installed on the second computer before? If it was, ActiveX version will work independently of activeXControlCodeBase path. This path is used only once for installation process. |

I have tried it on several different computers and this is what I have, and it works:
//For ActiveX control full path to CAB file (including file name) should be specified.
iu.activeXControlCodeBase = "../ImageUploader/ImageUploader4.cab";
iu.activeXControlVersion = "4,0,47,0";
//For Java applet only path to directory with JAR files should be specified (without file name).
iu.javaAppletCodeBase = "./ImageUploader/";
iu.javaAppletCached = true;
iu.javaAppletVersion = "2.0.50.0";
And the files are in the same folder.
I have another thing though, that I didn't notice before. It seems like the page reload when you press the yellow IE bar to approve the ActiveX. A reload makes my site log out (I have frames and a complex login system), and therefor you need to relogin and go back to the page with the ImageUploader before you can install it. Really anoying, but I quess it is no work around that you know of?
I write this here because I think I didn't need to relogin the first time. But I can imagine the wrong path makes the yellow bar click reload.
Sincearly

Page reload after ActiveX control installation is normal behavior for IE. Unfortunately I don’t know any workarounds for this case. Edited by user Monday, February 25, 2008 6:25:29 PM(UTC)

I have decided to use java for everyone. This is fine since most IE users can handle applets too.
Meanwhile, my evaluation time expired (I need to test it a bit longer). And I followed all the steps and didn't managed to get the applet on the server to work.
I'm not a good customer :( ....
I managed to get it to reload by changing version, and I did reload the installer and copied the jar file to the server. Though I couldn't seem to figure out my account on MyAurigma and had to register a new user, can this be it? Also, I only executed the ResetIUEvaluationPeriod.reg localy, do I need to do that on the server too? (I have no access right now)
Best regards
