Icetea exception

Mon Jun 27 15:49:41 UTC 2016

Hello Cezar,

Bingo! Like I have assumed. The OBJECT element in the HTML document has been 
authored incorrectly. Look here:

> 						<object
> 						    classid = "clsid:CAFEEFAC-0015-0000-0012-ABCDEFFEDCBA"
> 						    codebase = "http://java.sun.com/update/1.5.0/jinstall-1_5_0_12-windows-i586.cab#Version=5,0,120,4"
> 						    WIDTH = "640" HEIGHT = "480" NAME = "ucx" >
> 						    <PARAM NAME = CODE VALUE = "ultracam.class" >

First, "class" is a reserved keyword in the Java programming language and 
therefore must not be a package name. Second, the ultracam class has not been 
specified with its fully qualified name. The VALUE attribute of the PARAM 
element must state the fully qualified name of the applet's main class.

> 						    <PARAM NAME = ARCHIVE VALUE = "ultracam.jar" >
> 						    <PARAM NAME = NAME VALUE = "ucx" >
> 						    <param name = "type" value = "application/x-java-applet;jpi-version=1.5.0_12">
> 						    <param name = "scriptable" value = "false">
> 						    <PARAM NAME = "accountcode" VALUE="YWRtaW46emd1cmFUTnc=" />
> 						    <PARAM NAME = "codebase" VALUE="http://10.1.1.1:80/admin" />
> 						    <PARAM NAME = "mode" VALUE="0" />

Essentially, the same applies here too.

So, what can you do now? a) You should report this bug do the camera vendor and 
wait for a firmware update. b) In the meantime, you can download the 
ultracam.jar JAR file, find the fully qualified name of the ultracam class, put 
it into the HTML document and launch it from your local computer. There is 
nothing IcedTea-Web developers can do here.

Regards,

Jacob
