I'm writing software via NetBeans to interface with a Ocean View spectrometer and I'm running into an issue with deploying my jar file to a Raspberry Pi 3 without running into a n RunTimeException. I correctly followed the steps to deploy remote java jar files on the NetBeans IDE, but can't get past this error "Caused by: java.lang.RuntimeException: Failed to load any native library for USB. Tried base filenames: NatUSB_32, NatUSB_64"
Screenshot of the error in console here
My code runs successfully when compiled on the IDE, but not on the Raspberry Pi. I'm using JDK 8, and have the class path set to include OmniDriver.jar. Any help on troubleshooting this issue would be appreciated!

I have a Raspberry Pi 3b+. I wrote a .NET Core 5.0 program which uses Selenium to do some tasks on the browser. It all works 100% fine on my Windows PC. But it has errors when ran on the Raspberry Pi running 64 bit Ubuntu Server Focal version. I have the Gecko driver and Firefox installed. The program is able to complete its tasks, but throws many many errors about:
"Crash Annotation GraphicsCriticalError: |[0][GFX1-]: glxtest: Unable to open a connection to the X server (t=4.70096) [GFX1-]: glxtest: Unable to open a connection to the X server"
"JavaScript warning: https://js.arcgis.com/3.38/esri/dijit/BasemapGallery.js, line 22: WebGL warning: : WebglAllowWindowsNativeGl:false restricts context creation on this system."
"* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)"
"JavaScript warning: https://js.arcgis.com/3.38/init.js, line 1171: Failed to create WebGL context: WebGL creation failed:"
I tried installing xvfb but that did nothing. I am running headless and the driver confirms that I am running headless, but seems to be expecting a display regardless????
How do I solve these errors? Note, I do not care if I have to use Firefox, Chromium, or some other browser. But it seemed like Firefox was the most straightforward to install.
I figured it out. I changed operating systems to Raspberry Pi OS 64-bit Lite beta, easily installed Chrome and Chrome Driver... no problems.
I guess the problem was when running Ubuntu, the package repositories had mis-matching versions for arm64 packages and some things installed via 'snap', which is a no-go for programs that have to work together. On the Raspberry OS repository, they had matching versions and no 'snap'. At least it all works now in case anyone else sees this.
I'm attempting to build the Uno project template with Linux support, using WSL (Ubuntu 20.04), following the official guide.
Unfortunately, I always get an error running the Skia GTK project template:
DllNotFoundException: Gtk: libgtk-3-0.dll, libgtk-3.so.0, libgtk-3.0.dylib, gtk-3.dll
I tried adding libgtk-3-0.dll's folder to the Windows PATH, but this didn't help. Then I tried installing libgtk-3 in WSL, but it just changed the error to Can't open display :0.
What am I doing wrong?
The Skia.Gtk backend expects a running X Window server to connect to.
The guide suggests installing vcXsrv, an X11 server for Windows
You'll need to start the server in "Multiple windows" mode, starting with "no client" mode.
I have an IoTEdge module which runs a deep learning model on a Raspberry Pi 3 and runs well but then somehow returns this error:
Error: Time:Mon Jan 28 22:45:21 2019 File:/usr/sdk/src/c/iothub_client/src/iothubtransport_mqtt_common.c Func:InitializeConnection Line:2230 mqtt_client timed out waiting for CONNACK
Is this a network connection issue? It seems afterwards, this error disappears. Not sure why this is the case. I thought there might be a communication error between this IoTEdge module and the IoTHub, so I even restarted the IoTEdge module and rebooted the Raspberry Pi device.
How can this be resolved? Does it have to deal with a time.sleep(1) code in Python?
You are using the original version of the Azure IoT Python SDK. This is a wrapper around the C SDK and the message you are encountering is a known bug in the C SDK. This has been fixed in the C SDK but was never propagated into the Python v1 reposiotry.
I suggest that you rebuild your Edge module using the new Python v2 SDK (https://github.com/Azure/azure-iot-sdk-python). By default, this is the version now used by the Visual Studio Cloud Azure Edge extension.
We have followed the silent installation procedure on remote server as mentioned in the IBM Developer documentation of 6.3 from the link:
https://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.installconfig.doc/dev/t_silent_installation.html
Downloaded the MobileFirst CLI 6.3 file from the link::
http://public.dhe.ibm.com/ibmdl/export/pub/software/products/en/MobileFirstPlatform/mobilefirst_cli_installer_6.3.0.zip
unzipped it to MobileFirst CLI 6.3.0 and copied installer.properties file with fallowing content in that,
LICENSE_ACCEPTED=TRUE
USER_INSTALL_DIR=/opt/ibm/Worklight-CLI
and staying in the same folder, i installed the CLI 3.0 to the specified folder:
./install_linux.bin -i silent -f installer.properties
App has installed to the /opt/ibm/Worklight-CLI directory.
We then created a sample app as per Command Line commands specified in the link:
http://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.dev.doc/dev/r_wl_cli_commands_and_their_definitions.html
$ mfp create MyProject
$ cd MyProject
$ mfp build
$ mfp deploy
After app build and deployment, when we tried to check the MobileFirst Console over browser, with link:
http://xxx.xxx.xxx.xxx:10080/worklightconsole
after logging in to admin/admin credentials, page shows, loading the environments, but after waiting for 30 sec or more, it throws error as in the attached image.
But in log file shows some JAR file are missing. And i tried installing fresh copy of MFP 6.3 many times. but all time the same issue.
Please find the attached logs file and screenshot.
I am not able to find out what is the exact problem.

You've only linked to the documentation. Please edit the question and describe what you've actually done.
These are the steps I have taken (based on the CLI tutorial) in order to create a new project and application using MobileFirst CLI and then open MobileFirst Console:
System:
OS X 10.10.1
Oracle Java (default installed by the OS)
In Terminal:
cd /Users/idanadar/Desktop
mfp create testProject
cd testProject
mfp add hybrid testApp
mfp start
mfp build
mfp deploy
mfp console
The console was opened:
Check to see if there are any spaces in the path for your eclipse workspace. There is a known limitation with Liberty 8.5.5.3, which is the internal development server included in MobileFirst Platform Foundation 6.3, that you cannot have whitespace in the path name:
https://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.getstart.doc/start/c_known_limitations.html
The failures, which match what shows in your log file, can occur on console startup and app deploy or preview.
The Issue is with the Hosted Server. They have opened the port 10080 partially. as port is allowing one way communication. because of some security reason, Hosting Server organisation has put some restriction over it. Now its resolved. Now we can able to deploy, and check the deployed apps over the worklight Console.
Thank you all for your suggestions and effort to go through my long listed question and trying out to resolve it.
I posted this comment: as some other persons may face same issue. so at least they can rid of this kind of issue ASAP.
I am a web developer and new to Phonegap..
I was trying to install phone gap on my windows 7 machine as per described here
http://docs.phonegap.com/en/3.1.0/guide_cli_index.md.html#The%20Command-line%20Interface
but when i run the following command
cordova platform add android
i am getting the following error
[Error: An error occured during creation of android sub-project.
ERROR : executing command 'ant', make sure you have ant installed and added to y
our path.
]
does this mean that i should install apache ant on my machine ? if so can someone redirect me to right link.
I am also running wampserver on my machine for my other developments..
will installing 'ant' affect on my wamp ?
As described in PhoneGap Getting Started
Finally, you may need to include %ANT_HOME%\bin to your PATH as well. To check to see if this is required, run a command prompt and type ant. If the program can not be found add %ANT_HOME%\bin to the PATH. You may need to specify the full path instead of using the %ANT_HOME% environment variable.
If you need ant for Windows, you may want to download and install it from here
You need ant to add the android platform.
Ant is a java-based build tool.
You can get further informations and download it at http://ant.apache.org.
ant has nothing to do with the apache webserver and doesn't effect your wamp installation. It's another software product provided by the apache foundation.
