I've been installing Fedora Commons on a Fedora 17 system. Everything has just gone like a charm and I followed this guide:
http://asingh.com.np/blog/fedora-commons-installation-and-configuration-guide/
However, whatever I do the service "Fedora Commons" won't start. There is nothing showing up in /var/log/messages
Running "service fedora start" ends with an OK, but when I afterwards run "service fedora status" it shows "Fedora Commons service is stopped".
Any ideas?
Fedora Commons can be somewhat picky about having an environment set up correctly. In general I prefer to install a new Tomcat servlet container and then choosing the "existingTomcat" custom install rather than having the Fedora Commons installer create a servlet container for you. By doing this you can more easily separate the servlet container install/config issues (lots of documentation on the web for this) from the Fedora Commons install/config issues (not so much information on this).
Also, when doing a new Fedora install I find it helps to download and deploy a servlet called "psi-probe" into the Tomcat container. It helps debugging environment issues as well as giving you an easy way to view log files for all your servlets from a common web interface.

Further update: I forgot to mention one thing that also would prevent Fedora Commons from running and that is Fedora Commons does not seem to work well with the OpenJDK installed by default on many OS distributions. This can cause Fedora Commons to quietly fail with no log information even if the install was successful and correctly configured. Switching the environment variables to point to another version of JDK (other than OpenJDK) will resolve this problem.

I have failed to install Apache Zeppelin (v. 0.7.1) on my Windows 7 desktop.
I would like to proceed without having to install Docker, however.
I tried reinstalling the Java runtime etc. but Zeppelin does not start.
Any suggestions?
(I am aware of version 0.7.3 but don't feel like wasting even more time trying it on Windows 7).
Please share the errors your are getting. Confirm you have made all the settings (environmental or otherwise) as required.
Last week I finished development on a test app and ran it successfully in all simulators.
Today I decided to look at publishing the app and used "Sent Android Build". Build status "Successful".
Then tried running jar from command line and got:
peter#PeteSuse:~> java -jar "/home/peter/NetBeansProjects/mobile-apps/pGame/dist/pGame.jar"
java.lang.ArrayIndexOutOfBoundsException: 0
at com.codename1.impl.javase.Executor$1.run(Executor.java:84)
at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311)
So tried to run from GUI and got:
run:
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: javafx/embed/swing/JFXPanel
at com.codename1.impl.ImplementationFactory.createImplementation(ImplementationFactory.java:69)

Java version:
peter#PeteSuse:~> java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (IcedTea 3.3.0) (suse-23.1-x86_64)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
I am using Netbeans (new to this) on Suse Linux 42.1 64b.
Have I lost a library somewhere? or something else?
Thanks guys. I fixed the problem by adding jfxrt.jar to the Libraries in NetBeans.
JFXPanel is in the JavaFX library.
See: JavaFX and OpenJDK for info on why JavaFX is not available by default in your OpenJDK distribution.
If your linux distribution makes an open JavaFX package available (like ubuntu does: Why is JavaFX is not included in OpenJDK 8 on Ubuntu Wily (15.10)?), then you can use that.
Otherwise you can build from source (for the adventurous yak shaver).
Or, easiest, is just to an Oracle Java distribution.
I don't know codenameone or have any idea how it works. Possibly whatever it is, you could ask the creators to package their thing as a self-contained application, so that it ships with a compatible Java runtime, which would (potentially) avoid issues such as you are encountering. Not knowing codenameone, I don't know if that would make sense or not.
I also don't know the cause of your original ArrayIndexOutOfBoundsException as that looks internal to codenameone or your use of it.
With regards to NetBeans, you might need to set the Java platform to one with JavaFX installed (in case you have multiple Java platforms installed on your machine).
You can run a Codename One application in the simulator by pressing the play button in the IDE. It won't work for you from Command Line and shouldn't since the app shouldn't have a main() method.
You can execute the Codename One simulator from Command Line using:
java -jar JavaSE.jar:dist/MyApp.jar
Notice this assumes your project is the working directory.
I installed droneapi in the same manner given in the tutorial. However, it's missing all of the important modules that come with MAVProxy, such as console, wx, etc.
Was it supposed to install these modules, or should I move them over from MAVProxy itself instead?
Note: Windows 8 64-bit platform
I apologize that you had to investigate the issue without guidance. Publishing our Windows installer was not well prioritized, and it looks like that choice cost you several hours.
Here is what we will soon to address DroneKit Python installation on Windows:
A dedicated Windows installer generator lives at windows/droneapiWinBuild.bat. This generates a program Output\DroneKitsetup-1.x.x.exe which can be used to install all dependencies.
Yesterday we began testing the installer on Windows on every commit. https://github.com/dronekit/dronekit-python/pull/236
We will now publish the binaries generated by that test and document them in the Windows installation process. https://github.com/dronekit/dronekit-python/issues/164
Thanks for publishing your solution publicly. Hopefully we can address issues like these before they come up in the future.

So in a rare spark of intuition I discovered the answer. The modules required by Dronekit Python can be installed in the following ways:
Console- type "pip install console" into the WinPython cmd prompt
WX- http://wiki.wxpython.org/How%20to%20install%20wxPython
OpenCV- Download and install OpenCV version 2.4, then copy/paste the file cv2.pyd from OpenCV\build\python\2.7\x64\ to \python-2.7.6.amd64\Lib\site-packages.
At this point it should load all required modules, although it will throw a few exceptions which aren't important.
As always, 3DR documentation is incomplete. One would think that $800 million dollar profits would mean that they could hire more than 5 programmers for their new platform...
I am attempting to run foswiki on OpenBSD. Things are installed and i am able to open "/bin/Configure" page of foswiki configuration screen. but the page reports few errors, complaining that following files are either not found or outdated and new versions are required.
The Files are : grep, rcs, ci, co,rlog, rcsdiff
I tried commands like "pkg_add -Uu" to upgrade packages installed, but it reports all packages are uptodate.
I also tried "pkg_add rcs" "pkg_add grep" etc but non works.
So my basic question is how to I update above files to their latest version required by foswiki.
Regards
While I’m not familiar with Foswiki, my first thought is your web server is chrooted, as this is the default on OpenBSD, and, as a result, Foswiki cannot find the files it needs. You can copy the files Foswiki needs into the chroot or run the web server without chroot, which is bad from a security perspective.
all programs mentioned are part of a base openbsd install and the above answer is correct. the openbsd documentation on chrooted apache has more info.
if you don't have to stick with foswiki you can try dokuwiki instead which has package support on openbsd and installs easily in very much the same way you tried already:
sudo pkg_add -U dokuwiki
hope the process is pretty much self-descriptive. in addition, the manpage for pkg_add is a good thing to read. good luck!
The introduction says:
Follow the instructions on the download page to install the SDK on
your computer.
But the download page has no any instructions about how to install and what to do next. Only links.
All I found is this link to WindowsInstallation:
Download and run the latest Windows installer from our downloads page
Must Windows XP users use the installer? Can they just download the Linux version and unzip it? I'd like to have a portable version rather than one that installs EXEs and registry settings, etc.
Also I do not understand what exactly do I have to choose. There are:
Google App Engine SDK 1.7.7 (.msi file)
Google App Engine SDK for Go 1.7.7 (.zip file)
I've downloaded the second. Do I need to download and install the first too? Just adding the second to the PATH and develop is exactly what I want. Is this enough?
The Linux version will have executables compiled for Linux, so you can't run those on Windows (unless you run linux under a virtual machine with VirtualBox, VMWare or similar).
No, you do not need to install something to run Go GAE on XP.
I just downloaded go_appengine_sdk_windows_386-1.7.7.zip from
here.
Unzipped it in C:\go_appengine-1.7.7
Added the folder in my PATH. The main goal is to have these files
dev_appserver.py and appcfg.py in the PATH. It is written
here. Not a must, though, only for convenience.
Installed Python 2.7.4. Only works with 2.7.4. At first I installed
the latest 3.3.1 but had to change it to 2.7.4 because Go GAE cannot
run, throws an error.
And that's all. Just created a sample script, ran C:\>dev_appserver.py myapp and opened my sample app in localhost:8080.
PROFIT.
But:
Do not know, though, what benefits the installer offer. I didn't test it.
That was just a sample script. Maybe some serious development requires installation.
