Ubuntu Installation :: Missing Rights To Run Java Applet In Browser After Upgrade To 10.04?
May 7, 2010
I'm having a very strange error after upgrading to (K)Ubuntu 10.04.. basically Java Applets don't work in any browser (tried with Firefox, Chrome and Opera). The applet loads (plugin and JVM detected by all browsers) but it is grayed out. After trying all possible solutions I could think of (including installing alternatives jvm) I tried to run the browser as superuser: the applet is then working correctly. So somehow it seems to be a user right problem, but I'm not sure where this is coming from, both java (sun-6) and the browsers were installed and working ok in 9.10. Here is the directory list of /usr/lib/jvm/java-6-sun/jre/lib/i386
Code:
drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 client
drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 headless
drwxr-xr-x 2 root root 4.0K 2010-05-07 14:03 jli
[code].....

In my box Sun java and Open JDK co-exists. My problem is, despite been able to run java softs I can't run java applet in my browser (Opera mobile emulator, Facebook photo uploader etc).
Opera is my primary browser (Version 10.60 beta) and have FireFox 3.6.4 as the second choice. Both the browsers are malfunctioning when it comes to Java.

I was running Ubuntu 9.10 on my HP G70 laptop and did an upgrade using upgrade manager to Ubuntu 10.04.
Since I haven't been able to get wifi connection or wired working. The Network Manager applet is missing from the notification area and if I try to run nm-applet manually it says it is already running. I tried killing the process and then running it manually in the terminal and although the process appears to be running it is missing from the panel.
Booting into the live cd has the applet working fine so something in the upgrade process must have failed.
I tried changing the theme to see if it displays in other themes but had no luck.
I also tried to log into kde but kde seems to be broken. When I log into it after the splash screen all I get is a black screen with only my mouse pointer.

I thought I knew what I was doing, just a minimal install of slackware 13.1 for a game server (minecraft), but it seems I missed java or something - I get the "command not found" error. gcc-java is installed. What package did I miss/what series is it in? Does it have any dependencies?

I installed java applet for Firefox. It seems that I get the same message all the time "Install missing plugins". The path libjavaplugin_oji.so is located at:
Is there something wrong with the path ?

I recently upgraded from fedora 10 to fedora 11, everything seemed to go fine until I started eclipse and noticed that the java perspective was now missing. It was there before the upgrade, but something seems to be broken now. However, I can't find any error files, so I have no clue as to what may be broken. I looked around online to see if anyone else had a similar issue, but could not find anything that seemed to help. One site suggested that it was caused by not having the eclipse-jdt package installed, so I double checked that but already had it installed.
$ rpm -qa | grep -i eclipse | sort
eclipse-jdt-3.4.2-9.fc11.x86_64
eclipse-platform-3.4.2-9.fc11.x86_64
[code].....
Another site said that something in my .eclipse directory might have been corrupted and suggested moving it and letting eclipse create a new one, but this all did not . I was unable to find any other information about what could be causing this or how to fix it.

I have just installed Ubuntu 10.04. When trying to run a Java Applet on a web page I discovered that Java is not installed in 10.04 and the SUN Java JRE is not available to install any more so I installed the OpenJDK and IcedTea Plugin.
Most applets work fine but one specific, for me a very important one, dos not. Specifically the log inn applet used in my net bank: URl... See login entry on top left.After entering userID I am redirected to a page giving the following error message:HTTP 404 - The resource cannot be located. The file cannot be found. This applet runs fine in Windows.I have started Firefox in a terminal window but do not get any error messages there when trying to start the applet.The applet runs fine in Opera (though slow start up) in Ubuntu 10.04. Opera does not use plug in but run the applet directly from JRE. This indicates that the problem could be in the IcedTea plugin.

Code: ~ $ /usr/java/jre1.6.0_25/bin/java -showversion Error occurred during initialization of VMjava/lang/NoClassDefFoundError: java/lang/Object
That's the error I get. When trying to run a java app with the firefox plugin, the browser simply crashes if it's the 64bit java or tells me it's not installed if it's the 32bit version.
I'm at a loss as to what to do. I think it has something to do with leftover gunk from a previous version I misinstalled(Is that even a word?) Anyway, the only thing that google could come up with was a solution for windows which laid blame on Bill Gates for having a bunch of pf (java prefetch) files stuffed into c:windows for no apparent reason. The solution was to delete them, but I can't seem to find the java prefetch folder in linux. The method I used is downloading the rpm from java.com the rpm2tgz then installpkg then cp libnpjp2.so to firefox plugins folder.

Also if I try to re-add it to the panel it is not listed at all.
How can I restore it?

My code (provided by my Java instructor):
Code:
I get 1 of 2 errors, depending on my config:
1) If I run it with <default config>
2) If I run it with Web Start
I need NetBeans to work with applets for my Java class.

Ok here's what I'd like to do:
Take a screenshot, or some other way of saving the visual output of a java applet [URL], and saving that as an image, without having to manually do it (open browser go there, and take a screenshot).
I guess this would be most easily done using a script of some sort, but I have no idea how to go about doing this..
I would like to do this, so I can use this image to update my conky every 30 secs or so (got that part figured out ).

I upgraded one of my VMware VMs that was running 9.10 to 10.04 and it seems everything is working except my ability to connect to WebEx meetings. My guess is that it is a WebEx programming issue but I thought I'd post here too in case someone knows a work around.
When I attempt to "start" my WebEx meeting I immediately get this error:
"The requested URL /tc0505lb/webcomponents/docshow/docshow.do_siteurl=ciscosales&jvm=1.6.0_18&isJavaC lient=true was not found on this server."
My pre-Ubuntu 10.04 upgraded VM is able to start a WebEx meeting just fine.

I used about all available OS 's. In all systems I used a quick acces system like the file browser applet in Ubuntu. In fact I "cannot live without", specially if I am working on jobs and I have to work with a lot of files in different directories. Opening lots of folders and endless clicking is really not an option to me. Does anyone know if there is such an applet or possibility in Unity (because gnome 2 applets will not work in Natty)?

if there is someone who asked the same question, but I have the Ubuntu 10.10 net-book remix version, and every time that I go to try to download and install the Java applet, it will download Ok (I think), but when I try to open the file, there are no errors, but it won't open. When I try to re-download, it does nothing again.

I recently upgraded an ASUS netbook through a series of about 4 or so upgrades ending at Maverick (10.10). Sound in Java applets worked fine before that, but I've been trying for about a week now to get it working again.
Here is what I have tried so far:
Removed Sun Java and plugin, and installed Openjdk and icedtea
Removed Openjdk and icedtea, and installed Sun Java and plugin
Verified through aboutlugins that FireFox plugin matched installed Java plugin
Tried using padsp and aoss wrappers
Along the way I have also tried other suggestions I have found through Google for configuring sound and setting file permissions, but nothing works. No matter what I do, sound keeps working everywhere except in Java applets.
Here are some observations along the way.
Sound has worked everywhere I try except in Java applets. It works with Flash.
Java applets work fine except for sound. Java console indicates that sound files are being received and passed to applets.
My Java executable is located at /usr/lib/jvm/java-6-sun/jre/bin/java. I have tried renaming it "java.real" and creating a shell script that wraps it with padsp or aoss. When I do that Java works, but Java applets fail to start. The Java console does not start up, so the wrappers appear to prevent applets from starting.
I am trying to run applets at [url]. They work fine for me on a 64-bit 10.04 system and a 32-bit 10.04 system.

I am connected with chinese-tools.com. They have a neat java applet which has a window in which you can draw a Chinese character, and it will recognize it. However, this is causing my comp to go into overdrive. The twin processors are at nearly 100%. I have two Intel T1600s. If I kill the browser, google chrome or Mozilla, things calm down. It is definitely the applet causing this.
