    Default Need to get jar file working for web-cam

    Sorry if this isin't exactly a java programming question, but maybe someone here can help (I have no idea where else on the web I can get this question answered).

    I've got an IP-web-cam that when I access it using firefox, it keeps insisting that I have a missing plug-in and when I click on the "install plugin" link, it wants me to install the java JRE version 1.7.something. I already have the 1.6.something installed and working, so I don't know why it thinks it needs to install the JRE.

    I've come across this elsewhere on the web:

    I troubleshot the Firefox installation and found an incompatibility with /library/internet plug-ins/javaplugincocoa.bundle. Once that plug-in was removed, the video stream worked under Firefox with the same ultracam applet. Also tested successfully with Opera v9.62.

    This guy had the same camera, but found a way to get the streaming working on a mac (I'm on windows). I think the problem is with the file ultracam.jar. When I try to "install" it (by double-clicking on it) I get "Failed to load Main-Class manifest attribute". When I unpack it and look at, I don't see "Main-Class". What I see is:

    Manifest-Version: 1.0
    Created-By: 1.6.0_17 (Sun Microsystems Inc.)

    Name: ultracam.class
    SHA1-Digest: 7UxuH4Scb0tsxTPC2MGlW7YwHa0=

    Name: ultracam$Buffer.class
    SHA1-Digest: gho1wytYUzp5YTuv0RJiF/4Z9FU=

    That's it. That's the complete contents of

    So what's the deal here? What do I need to do with this ultracam.jar and firefox so that I can get streaming video from this IP-webcam?

    It isn't a Java programming question at all, and outside the scope of this site.

    I'm moving this to the lobby.

    If you're forever cleaning cobwebs, it's time to get rid of the spiders.
