Debian Programming :: Does OpenJDK Installing Completed
Sep 17, 2014
I'm running Debian Jessie 64bit, the X-window is xfce4, I found the 'OpenJDK Java 7 Policy Tool' entry is already under the Settings menu, it seems appeared after I customized jessie a little, that installing nvidia driver, virtualbox ose, adobe reader and adobe flash player. From console, I can check there is java, but no javac.For doing java programming, I don't know if the OpenJDK was complete installed or not, should I continue to use it or remove it to install Oracle JDK?
how do I uninstall Java? Tried with Synaptic and apt-get remove, but uninstalling sun-java6 automatically adds default-jre (openjdk) and uninstalling openJdk automatically installs sun-java ... but I don't want ANY Java on my machine - am I missing something? Already thought I maybe have a package that requires SOME kind of Java, but how do I find out?
OpenJDK has recently updated. Problem is that I am using the JDK from Sun/Oracle which I downloaded and installed along with other java tools and IDE's. I notice that openJDK is now the default JDK on the system.
java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.4) (6b20-1.9.4-0ubuntu1~10.04.1) OpenJDK Server VM (build 19.0-b09, mixed mode)
Now my own java build is configured in $PATH but ignored, this is not good as I do a lot of java development. I would like to disable the OpenJDK or even remove it. I would also like to disable the update manager for this particular package and it's other add ons.
I have the following packages of openjdk and icedtea installed. i openjdk-6-jre - OpenJDK Java runtime, using Hotspot JIT i openjdk-6-jre-headless - OpenJDK Java runtime, using Hotspot JIT (headless) i openjdk-6-jre-lib - OpenJDK Java runtime (architecture independent libraries) i icedtea-6-jre-cacao - Alternative JVM for OpenJDK, using Cacao i A icedtea-6-jre-jamvm - Alternative JVM for OpenJDK, using JamVM
Now I am not a developer or anything just a user. My use-case are two :- a. Running java programs on the desktop b. Running java in the web-browser.
I *think* both of them get installed by default. Openjdk via the default-jre virtual package while icedtea due to some of the openjdk headless packages. ~$ aptitude why openjdk-6-jre i default-jre Depends openjdk-6-jre (>= 6b23~pre8-2~) ~$ aptitude why icedtea-6-jre-jamvm i openjdk-6-jre-headless Recommends icedtea-6-jre-jamvm (= 6b23~pre8-2) ~$ aptitude why openjdk-6-jre-headless i openjdk-6-jre-lib Depends openjdk-6-jre-headless (>= 6b17) $ aptitude why openjdk-6-jre-lib i openjdk-6-jre-headless Depends openjdk-6-jre-lib (>= 6b23~pre8-2)
Notice the circular dependency at the end. From what I read the headless packages are basically for those systems where a server is running which does not have have a monitor, in which case I wonder why its installed in my system? My actual issue is of having the java for iceweasel. I did search for having java plugins and did not find anything except for icedtea-plugin to run java on my browser.
Trying to install it through gave conflicts :- $ sudo aptitude install icedtea-plugin [sudo] password for shirish:
The following NEW packages will be installed: icedtea-netx{a} icedtea-plugin xulrunner-1.9.1{ab} 0 packages upgraded, 3 newly installed, 0 to remove and 4 not upgraded. Need to get 8,642 kB/9,103 kB of archives. After unpacking 26.5 MB will be used.
The following packages have unmet dependencies: openjdk-6-jre-headless: Conflicts: icedtea-netx (< 1.1.1-2~) but 1.1-1 is to be installed. xulrunner-1.9.1: Depends: libmozjs2d (= 1.9.1.16-6) but 1.9.1.16-9 is installed. The following actions will resolve these dependencies:
Keep the following packages at their current version: 1) icedtea-netx [Not Installed] 2) icedtea-plugin [Not Installed] 3) xulrunner-1.9.1 [Not Installed]
Accept this solution? [Y/n/q/?] q Abandoning all efforts to resolve these dependencies. Abort.
I did see the other solutions but most of them recommend downgrading both the openjdk and icedtea packages to the ones in testing rather than in unstable.
As I have developed a part of my project based on crontab and now one of my team member has raised a question based on performance and load/stress, I would like to know the following limits of crontab.I assume each line in crontab file is a task; and also crontab would hold completed and pending tasks.1. How many tasks (both completed and pending) could crontab hold/handle?2. Will crontab run as expected if there are 100s of completed and less than 100 pending task?
I'm running Debian Squeeze (6.0.1) 64-bit and I'm trying to run Microsoft Office 2007 (due to formatting issues with OpenOffice) through Wine (version 1.0.1 from the repositories). I followed the instructions over here but when I try to run the setup I get an error box with the following message:
Setup did not complete successfully. We are sorry for the inconvenience. An error occurred during the installation, and setup was unable to complete. Please tell Microsoft about this problem. And there are two button: "Send Error Report" and "Don't Send". And the installation is aborted. Is there anyway to make this run?
Last nights upgrade of java-1.6.0-openjdk-1.6.0.0-43.1.8.2.fc13.i686 and java-1.6.0-openjdk-plugin-1.6.0.0-43.1.8.2.fc13.i686 prevent the loading of Ameritrades Command Center.Downgrading to version 1.6.0.0-37 fixes the problem. I'll post the bugzilla number as soon as I get the chance to file it.
I'm running Debian 5.0. I've been following the tutorial here http://www.py2exe.org/index.cgi/Tutorial but it seems I can't get it to work. I'm guessing, Python didn't come with the Distutils that I need. I've search the repositories and the On-line debian package database, but can't find a Distutils package, I've installed python-dev, but that still appears to not contain the module for py2exe.
app deployment on Linux/debian and I'm using Debreate to create .deb packages which works fine. I install the software itself to /usr/bin but want to install the program's database to /home/username/myapp/ The problem is it that I don't know how to add the env variable 'username' to the target path. What is the exact syntax for this installation path?
I just installed F 15. I have a Java app that I use a lot that is buggy with OpenJDK 6, because OpenJDK 6 is buggy, and apparently it needs OpenJDK 7 to run smoothly. Is there an RPM for OpenJDK 7 somewhere? I haven't been able to find it if it exists.
I also need ffmepg but have been unable to find a RPM for it either I did try to build ffmepg form source but it wouldn't build because it was missing Git what ever that is, which in turn I couldn't find a package for. I'm trying to avoid going on a scavenger hunt to get this installed and that's why I'm looking for an RPM.
If OpenJDK7 and ffmepg do not have RPMs for F 15 what are my best options?
Is there a command that can be run to verify that a users cron job has run successfully? Platform is Ubuntu 8.04 LTS.
I have scripts in /home/useraccount/bin/ running crontab -l
While logged in as user results in: # m h dom mon dow command @hourly /home/useraccount/bin/script_1 @hourly /home/locateruser/bin/script_2 I realize scripts could send email or write to a log with a timestamp, but wondering if there is just a way to verify it ran from the command line.
I ran ps -ef|grep cron ... and it shows root 4358 1 0 Mar12 ? 00:00:00 /usr/sbin/cron Not sure if this indicates it is running the jobs though....

Is there a way to get a summary of how much bandwidth a given process used on Linux after the process completes? I do not want a monitor, I want something I can look at after the task has completed..
Ideally something like the "time" command or a profiler, but for network usage.
I'm writing a file handler script that monitors (via a cron job) a directory that is an openssh sftp target for new files. When it detects a new file, it moves it, does an scp to another system, and sends an email. The problem I have is that I can't figure out a way to verify that the sftp upload is complete before I start manipulating the file.

For example I am copying data to USB-flash drive using some file manager. When the file manager shows that transfer is complete, flash drive indicator continues to light. As far as I know this is some kind of caching system...
1. Is it OK to close file manager when transfer window is closed but the flash drive indicator continues to light (data is still being copied)?
2. Is it better if I turn off this caching technology?
When I try to print something there is only some led blinks on printer and nothing is print. I am using drivers from brother(cupswrapper). I am using CUPS 1.3.11. I didn't have any problems on my previous installation of slackware(but I don't know which driver I've used).
Ii want to install VLC media player in mandriva linux 2009. I have tried the rpm packages from rpm.pbone.net but the rpm installation is not completed. I have downloaded the vlc from www.videolan.org but unable to install it. I have mandriva 2009.0
I am learning network programming via a book of Richard Stevens.The sample source codes are given here http://www.unpbook.com/unpv13e.tar.gz I downloaded and unzipped the file in /usr/src folder.As per the instructions given in README of downloaded archive I did.
I've installed the newly released OpenJDK which includes the updated NPPlugin that's compatible with Firefox 3.6. However the CPU usage is abysmal. I'm seeing 80-100% by the java component. How I installed it and removed the previous Sun Java workaround is listed here.
My sig says 11.3, but I just did a new install to 11.4. I found a small problem with using openjdk 1.6.20 with one of my applications. I use Scottrader, proprietary Java application by Scottrade. It uses ports 80 and 443 for the data streams and I was not getting any data on 443 with openjdk. I stopped the firewall, just in case that was a problem, but it persisted. I solved the problem by installing Sun java 1.6.24, and running update-alternatives to use Sun java as the default. Data on ports 80 and 443 are running to the application now.
After reading the sticky on 10.04 regarding java, I would like to know that if I install sun-java from Medibuntu, do I need to uninstall Openjdk and Icedtea? Can these programs coexist? Should I uninstall Openjdk first and then install sun-java? I think the absence of sun-java on my Dell is the root cause of the crashing that is ocurring when I try and access my AOL mail.
I've been advised to "clear the java cache", and to do so under Windows, one would open the java control panel. Of course, I'm using OpenJDK, and not Java's java.
Can anyone tell me how I would clear the java cache?
