Java Plugin (icedtea-web) Does Not Load

Hi,

After some recent upgrade or the other, the browser plugin for java no longer works in my CentOS 6 x86_64 setup – using Firefox. Applets won’t load, and no java plugin is mentioned in “about:plugins”. The “openjdk” Java packages as well as icetea-web are installed, though, and everything worked just fine a few weeks ago.

Has anyone else seen this? Any idea what may be wrong and/or how to diagnose the problem? Should I expect error messages anywhere if the plugin just won’t load (can’t see anything in the browser console)?

Note that when I talk about upgrades, I mean that I generally install all “notified” system updates.

  • Does the file /usr/lib64/mozilla/plugins/libjavaplugin.so exist, and does it link (indirectly) to /usr/lib64/IcedTeaPlugin.so? You can check using the following command:

    readlink -e /usr/lib64/mozilla/plugins/libjavaplugin.so

  • I forgot to tell, I checked all “obvious” things like that. And yes, the file points where it should.

  • I’m sorry if that offends anyone, the the BS nature of e-mail footers like this one always offends my intelligence. As a recipient of e-mail I didn’t give my consent to be obliged to anything. whatever you sent me was at your sole discretion. You want any obligations from the recipient of your message, you should contact the recipient first and get him agree to be obliged to anything you request.

    Who is the idiot lawyer who wrote it? He shouldn’t even have layer degree for incompetence! Even I, not lawyer, do understand that you can not make the person obliged to do or not do anything by unilaterally doing something (sending that person e-mail with idiotic footer).

  • Well, maybe I get slightly offended by the fact that you direct this comment at me and/or the list. As if I had anything to do with it being added…

  • All I can think of is to run ‘rpm -V’ on the packages which own the above files, and also look for clues in ~/.xsession-errors and
    /var/log/messages upon starting firefox. I’m sure if those suggestions are obvious. :-)

  • You mean like forcing someone to agree to the terms of a license through the act opening the package that contains the text of said license? You would be amazed as what corporate interests have twisted the courts into doing for them through sponsored legislation (DMCA for example).

    I agree about the BS part but that does not make it unenforceable BS in some jurisdictions. And then there is always the threat of impoverishment through litigation. A big enough complainant can simply litigate frivolous torts to impose an economic penalty on its victim regardless of the outcome. Those sorts of disclaimers simple provide a pretext.

    I just delete messages with such things; unread whenever I notice them in time, otherwise ignoring the contents if I do not.

  • It’s all noise and such nonsense should be restricted by policy by list owners. If people can’t figure out email by now they need to go back to using pencil and paper.

  • It is your email that has that footer. If you didn’t know your e-mail has that footer, you have been told. If you didn’t know an idiocy of your e-mail footer offends other people, now you should know it too. If you disagree with the fact that part your e-mail offends people the least you can do is to stop using that server/service.

    If I missed something or made any mistake, I’m sure others will add/correct me.

  • Well, I guess the “obvious” was mainly verifying that the file was actually there :-)

    The log files you mention didn’t offer a clue about what was going on, but another file did – pluginreg.dat in the profile directory. It actually had

    [INVALID]
    /usr/lib64/IcedTeaPlugin.so:$
    1385126043000:$

    I then remove the file and restarted, and now everything is back on track :-)

    I now remember doing this for other plugins in the past, but I’d quite forgotten that there even was such a file until I was reminded by a web search…

    Another question is why the plugin was considered “invalid” in the first place, of course. Maybe I’ll never find out…

  • It should be pretty clear in this case that the “intended recepient” is the mailing list and consequently everyone subscribed to it. So what is there to make all this noise about?

    Furthermore, the information is added by the SMTP server (not the MUA), so it can’t be removed just like that, and due to firewall policies etc. it’s not very easy to send the messages via a different one. And trying to get this feature removed from the service would be fighting windmills.

    I should imagine that many corporate users face similar issues, so
    “restricting by policy” like you suggest would mean excluding all of them from the list(s). Is that what you want?

  • Wrong. Legally. It is sender and sender alone who knows one’s own intent.

    If you agree it is nonsense, start using free e-mail (gmail, hotmail, yahoo mail to name some, even though I may not agree with privacy policies of at leas some of them).

    I was expecting the list owner to kick one or both of us two and ban from the list forever. For creating unnecessary noise on the list. Would that happen, I will have to subscribe my different e-mail address (on another server I maintain as well). You (if you too will be banned from the list), hopefully, will start using free (as opposed to “slave”? – OK, disclaimer:
    just kidding, no legal catch on me here -;) e-mail address.

    As far as fighting windmills is concerned: I’m fighting against one of them being brought into my backyard (OK, not _my_, but the one of free community I’m member of).

  • I’m not so sure about that. Isn’t there is also the matter of what one may reasonably be expected to assume or understand, and that kind of thing?
    I think the note is unnecessary, but nothing to make a fuss about. Based on that,

    1. I can’t see why I should let work-related e-mails bog down one of my
    private email accounts.
    2. I don’t think I have a good enough reason for degrading to one of
    those annoying web interfaces. (Like I said, I can’t use a real
    email application with an outside address, thanks to the firewall.)

    That would be more reasonable ;-)

    Well, good luck on that.
