Ubuntu :: When Installed Netbeans It Didn't See The Java Installation?
Jul 2, 2010
and I've been using windows alone until now. There is something I don't quite understand in ubuntu and that is where do you install programs (something similar to the Program Files folder in Windows perhaps) and is there something similar to registry, because I installed JDK from a downloaded binary and when I installed Netbeans it didn't see the Java installation, and where exactly are the system files?

I'm not sure if this is the place to post this, but I'm having trouble with NetBeans.
I'm trying to run a Java applet.
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.

I'm trying to make a java application in netbeans 6.9.1 (ubuntu 10.10) and I need to use the webcam on the system. Now I found this project: [URL] I am able to run the program and see the vid imput from the webcam using: "java -cp /usr/share/java/v4l4j.jar -Djava.library.path=/usr/lib/jni au.edu.jcu.v4l4j.examples.DeviceChooser" The problem is how to import the libaries into netbeans, there is an explanation on the site how to do it with eclipse but I don't have any experience with ecplipse and judging from what people have to say about how it works I don't want that either. I get the following error as output:

I had just downloaded and installed Ubuntu. I had to manually install the Software Center. So I did that and installed a bunch of things including OpenJDK and its browser plugins. OpenJDK caused trouble in a game I play, so I installed Sun instead. However, that's the old version. I followed the above instructions, removed the old verisons and attempted to install the plugins. But unless I use the Software Center, it doesn't work. I'm cutting and pasting exactly and nothing shows up in my aboutlugin screen.

I try to install the java plugin but the java test pages show not installed. I have tried the openjdk-6-jdk package and the Oracle/Sun 1.6.0_26 version to no avail.
Is there some good instructions page someplace? I have yet to find a set of instructions that provides something clear that works.

Do Windows XP, Vista, Windows 7 and all Linux distributions have Java JRE installed so end-users don't have to install it to run Java applications?

I've really borked up my Gimp. I'm running 10.04 64-bit and had at some point installed gimp but don't recall how or where I got it from. The strange part is that neither Synaptic or Ubuntu Software Center showed it as being installed.
Anyway, it started misbehaving (locking up) so I figured I'd uninstall and reinstall. That's when I discovered that the system didn't show it as being installed at all. Needless to say, I couldn't uninstall it so I decided to just reinstall over the top through Ubuntu Software Center. The installation seemed to complete normally but when I tried running it I got an error stating that there was a version mismatch for libgimp and suggesting that maybe I had gimp installed in both /usr and /usr/local. Not knowing what else to do, I uninstalled via Ubuntu Software Center and then removed all gimp related files from both /usr and /usr/local. Lastly, I reinstalled again via the Software Center.
Now when I try to launch gimp I get a box in the panel's Window List titled "Starting Gimp Image Editor" but shortly thereafter it disappears and I'm back to the desktop. I've even tried it all over again but utilizing Synaptic for the final install (as well as apt-get) with the same result - it tries to load and then... nothing. I must have deleted something essential when rooting around in /usr and /usr/local that is not replaced by reinstalling gimp but I have no idea what or where. So now what do I do? I really need gimp installed on this machine. I do have a full system backup but it's a couple of weeks old and I don't want to lose all of the changes that I've made to the system since then.

I run apache on a non standard port(82).I just installed unity to play around with it and while I was playing with it I installed prixfixe through software center to edit the menus.While prixfixe was installing my computer was acting very slow which was odd, but not completely unusual.During this time I ran ps aux which showed that my apache server was taking up most of the processing power.I was about to stop my web server,but I waited just in case the web server was updating a few things (I run ampache).
My computer finished installing the software and then I ran some command with sudo (I can't remember what the command was), but it threw back some message saying "setid blabla". I restarted my computer and when I got to my gdm my normal user account did not show up. There were no accounts and the restart/shutdown buttons didn't work.Now I'm running on a livecd and checking out my apache access logs, apache error logs,and kernel logs,but nothing looks out of place..

I'm trying to do a coursework at home which is a java web app. I've installed Tomcat and mySQL, both appear to be working fine. I have Netbeans installed already - from the Ubuntu Software Centre ages ago - when creating a new project it doesn't give an option for a web app project.... Is there some extra package(s) I have to install ?

I installed NetBeans 5.5.1, then upgraded ubuntu and installed NetBeans 6.5.1. Finally I upgraded to Ubuntu 10.10 and installed NetBeans 6.8. I tried to uninstall those unwanted previous versions of NetBeans using
Code:
:~$ sudo apt-get --purge remove netbeans5.5
Code:
:~$ sudo apt-get --purge remove netbeans6.5
But it gives message
Code:
:~$ sudo apt-get --purge remove netbeans5.5
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package netbeans5.5 is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
The problem is there is no installed version of NetBeans 5.5.1 and 6.5.1 but there are two menu items
Applications -> Programming ->NetBeans 5.5.1
Applications -> Programming ->NetBeans 6.5.1
How to remove those menu items from the system with remaining files if there is any?

I have both the openjdk-6-jre and sun-java6-jre versions of java installed on my Ubuntu Maverick desktop, with the sun version setup as the default. I was trying to load the web page,URL..., an amateur radio software defined receiver. I can load the page on Firefox run on XP in a VirtualBox machine, but when loaded on Firefox on my Maverick desktop, I wasn't getting any sound with openjdk, so I installed sun's and set it as the default. When I run 'java -version' from the command line, it reports the following:Java(TM) SE Runtime Environment (build 1.6.0_22-b04)Java HotSpot(TM) Server VM (build 17.1-b03, mixed mode)but on firefox, when loading the above page, it reports 'java version test applet 1.6.0_20' on the page. How do I get sun's version to run? I need to get the sound to work.

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.

using Xubuntu 11.04
I don't like Firefox 4 and 5 so I uninstalled it and installed FF 3.6.19 manually in the /opt directory. It works really well. I wanted to add a java icedtea plugin to FF. But I can't use Synaptics. Synaptics does not see the FF 3.6.19 - it does not know it's there and will try an install FF5 if I use it to install that plugin - makes sense it would do that.
How do I get a java plugin installed considering how FF is implemented on my system?
I can download a deb installer for the plugin and use the archive manager to get manually get files out of it but what I've tried so far didn't work...

I've purchased a couple of books so that I can begin to learn JAVA. Finding recent editions is very challenging, so the books I found cover JAVA 5.0. I plan to go through all of the exercises in both books. Which version of Java should I have installed on my computer?
Should I install 5.0 so that the examples from the book will work perfectly? Will I run into confusing situations or problems if I try the example exercises using Java 6?

Yesterday I disinstalled with yast java-1_6_0-openjdk-1.6.0.0_b20.1.9.2-0.2.1-x86_64 and java-1_6_0-openjdk-plugin-1.6.0.0_b20.1.9.2-0.2.1-x86_64 (which were installed as part of our sitewide suse 11.3 installation) and replaced them with java-1_6_0-sun-1.6.0.u22-1.2.1-x86_64 and java-1_6_0-sun-plugin-1.6.0.u22-1.2.1-x86_64 (et al) to solve my problem about bad graphics quality in firefox applets as described and suggested in this other postl.That successfully solved my applet problem, but I just discovered it triggered a new problem with openoffice . I tried opening an existing sxc document and got this error message:[Java framework]sunjavaplugin.so could not load Java runtime library: file:///usr/lib64/jvm/java-1.6.0-openjdk-1.6.0/jre/lib/amd64/server/libjvm.so.
It looks like that openoffice is still looking into the old openjdk instead of the new sun java. How can I repoint it to use the current java (assuming it really needs it) ? Apparently even entering openoffice on a new document gives error in a popupOpenOffice org requires a JRE to perform this task. The selected JRE is defective. Please select another version or install a new JRE and select it under Tools-Options-OpenOffice org-Java ... but since openoffice does not start I cannot access those options I guess (or is such stuff located elsewhere, and if so where) ?

I already enter the manual partition editor sectin, but the list show that my harddisk has no parition no it. The weird thing is that i can normally access my partition on ubuntu live-cd's file browser, but it didn't appear on my installation wizard. Here is a screenshot of my desktop:
