I am working on a scan applet for browser. I use Morena 6.4.
Everything works on my local PC.
Sometimes this applet is started behind Citrix application server (4.5 version). Everything for image scanning is configured ok - some native applications can scan (this application uses TWAIN, like Morena).
When I try to scan with Morena, I get this error:
SK.gnome.twain.TwainExcaption: Failed to load twain_32.dll (error=126)
Image of the error:
According to your description, it seems be a permission issue, i.e. morena doesn't have enough permission to load twain_32.dll. What I used to verify it is to run the application as administrator, i.e. right click on the app, choose "run as admin".
In addition, please double check if the DLL (twain_32.dll) exists in C:\Windows. If not, you can download or copy one to this folder.
Hope my answer helps.

I have a Unity project, where you can navigate around in a 3D space environment. I'm using Unity version 2020.3.4f1 Personal. I went to 'Build settings', chose WebGL, and then clicked 'Build And Run.
The project seems to launch on a Chrome browser in localhost, without any issues:
However, when I zip the build files & folders (index.html file along with the 'Build' and 'StreamingAssets'), then host as a website, all I get is a grey screen, instead of an interactive website!
As mentioned the build created is - index.html file, 'Build' folder, and 'StreamingAssets' folder:
Clearly, there's something wrong with the build as the project seems to run fine directly in localhost.
Any help would be really appreciated.
Many thanks
Edit
Looking at the logs in the Chrome browser console (running on localhost), these are the logs:
For the 404 error, I found some Unity forum thread: https://forum.unity.com/threads/webgl-builds-only-partially-working.357591/ , where I then thought the solution was to enable Data Caching & Decompression Fallback, and set Compression Format Gzip.
But this didn't solve the issue, as I still get the 404 in the console log, running on localhost (although as mentioned before, in localhost it runs). Also, when hosting it on a server using Netlify it still shows just a Grey window.
Note: strangely when I refresh the browser running localhost, the 404 disappears, but still the main thing is that when hosted on a remote server (Netlify), I just get a Grey window.
Localhost will be case-insensitive on Windows, while Linux is usually case sensitive on the Host. Check URLs and file names, and try looking at the Web server logs for 404 errors.
I have a simple MVC web application, which was running locally without problems 3 weeks ago.
When I now open the application in Netbeans and run it, everything seems to work fine as well. However, when I go to the browser (in my case google chrome) to look at the app's frontend (at http://localhost:8080/optimizer), I get the following error message:
HTTP Status 404 - Not Found
In Chrome's javascript console the following error message is given:
optimizer:1 Failed to load resource: the server responded with a status of 404 (Not Found)
"optimizer" is the name of the app. (What's the point of the "1" in "optimizer:1"? ... I don't get this either.)
The server (payara) is running:
I can also reach the server's admin page:
However, somehow the server cannot seem to find the application, although 3 weeks ago everything worked fine ... I just don't get it.
What's wrong? How can I fix this?
UPDATE:
Clicking on "List Deployed Applications" in Payara's Admin Console reveals that my app is not(!) deployed.
I tried to deploy it by clicking on "Deploy an Application" -> "Choose file".
I selected the jar-file "optimizer-1.0-SNAPSHOT.jar", selected Type "EJB Jar", then clicked on OK.
I got this error message:
Archive type of /private/var/folders/hh/hgq7wrjn5d51gy2tkbxkkbwh0000gn/T/optimizer-15075570634779987058.0-SNAPSHOT.jar was not recognized
How can I deploy my app? And why did it work automatically before and now it doesn't work any more?
UPDATE 2:
A difference I realise compared to before (3 weeks ago) is that the browser doesn't open automatically any more when I run the app.
Furthermore, Google Chrome used to be the IDE'S default browser ... now there is just a grey globe and I can no longer choose Chrome as my browser:
UPDATE 3:
I just noticed there is an error message that appears when the server is started (it's in the middle of hundred of rows of log output so I didn't notice it at first):
UPDATE 4:
-> NetBeans IDE 11.2
-> Payara Server 5.193
Error clearly shows, server is not able to recognize archive type of jar,
Archive type of
/private/var/folders/hh/hgq7wrjn5d51gy2tkbxkkbwh0000gn/T/optimizer-15075570634779987058.0-SNAPSHOT.jar
was not recognized
From payara blog,
If you set “Location” by “Packaged File to Be Uploaded to the Server”,
the suitable type would be selected.
So, the suitable type would be selected automatically.
Also, optimizer-15075570634779987058.0-SNAPSHOT.jar is not an original jar optimizer-1.0-SNAPSHOT.jar
It seems that issue is with the path of an archive, from thread
Code in uploadFrame.jsf:
<sun:form id="form">
I probe to change it to:
<sun:form id="form" enctype="multipart/form-data">
in uploadFrame.jsf into console-common.jar file. And it works.
You can try with changing uploadFrame.jsf into console-common.jar file.
(Not sure if chrome takes care of this, as it was working for you with chrome).
You may also want to try manual deployment,
install-directory/bin/asadmin deploy PATH_TO_ARCHIEVE/optimizer-1.0-SNAPSHOT.jar
Ok, I now found out how to run the app locally without problems: by creating a .war file instead of a .jar file - now I can run the app again without problems.
I am new to worklight and am trying to understand the baic workflow. so i googled a little bit and found a link to start with a simple HelloWorklight project. But i am getting the following errror.
[2014-08-13 10:12:59 - Dex Loader] Unable to execute dex: Multiple dex files define Lcom/google/zxing/BarcodeFormat;
[2014-08-13 10:12:59 - IBMScanScannerAndroid] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Lcom/google/zxing/BarcodeFormat;
Also my eclipse says No ipv4 address found. my ip addresss is correct. Am i missing something? Please suggest me any configuration settings to be changed or something. I would be happy to see a basic app running on my phone.
I follow by https://www.ibm.com/developerworks/community/blogs/WASFAQs/entry/using_a_barcode_scanner_with_worklight?
Html: i tried both the code given above and also just text "hello Worklight".
Help is greatly appreciated.
If you want to see a basic app running on your phone, you should not start with a not-basic app (like an app that utilizes a Cordova plug-in).
Instead, you should read the IBM Worklight Getting Started training modules, where you will understand how to run a Worklight app at first, and then how to run a Worklight-based Android app on your device.
Please start from there.
Additionally, the IP-related log line is simply for your information; read it thoroughly. You can ignore it if you intend to work locally at this time.
If you want to see a basic "Helo World" app running on your device, read and then use the supplied sample project in the section "Hello Worklight".
My problem is that my content does not show at all on particular device/browser and only once bundled. The wep app display correctly in debug (running it from meteor) whatever the device or browser are.
EDIT : I can see the navbar and the footer but not the yield on affected devices/browsers
Affected devices/browser known to date are Chrome on Nexus 4 (not on Note3) and Dolphin on Note 3.
Dev environment is Windows and prod is Linux.
I've also tried to run the app through meteor directly on server and the problem is not here but is back even when I bundle the app from the server.
Any idea about what can cause that and/or how to troubleshoot that?
EDIT 2
I can finally confirm that it's a client side bug.
Here is the error from chrome console on the device
Exception from Deps recompute function: ReferenceError: Lists is not defined

But the Lists collection is defined, published and subscribed. And the weirdest part is that everything works well when debugging through Meteor
In my specific case, Collections definitions were located in a /collections folder at the root of the app. That caused the app to load them after the /client folder but only once deployed and on some devices/browsers only!
To fix that, I've just move the /collections folder into /lib, bundled it again, push it to the server and everything now works flawlessly whatever the device/browser is.
I just installed gentoo linux amd64.
on that I installed eclipse 4.2M5 with FD5 for flex development.
after compiling my project, when I execute it i get the following in the log file:
Error #2046: The loaded file did not have a valid signature.
Failed to load RSL http://fpdownload.adobe.com/pub/swz/tlf/1.1.0.604/textLayout_1.1.0.604.swz
Failing over to RSL textLayout_1.1.0.604.swz
Error #2046: The loaded file did not have a valid signature.
i use FD5 with Flex 4.1A.
any ideas why it happens ?
update:
it seems that when I close and open my project I am able to execute my project once. the 2nd time that I execute the project on my browser I get the error and I need to close and reopen the browser to execute it again.
First of all thank you for all of your comments.
I finally was able to properly resolve the issue.
it seems that flash saves cache info at ~/.macromedia
(~ for home dir, for example if the user is ufk so it translates to /homeukf)
all I need to do is to delete that folder, since then I am able to refresh my app on the browser without any problems.
