We had been migrating our projects to Linux from windows.Among which is a Java Applet being invoked from a JSP to facilitate scanning via JTwain API.This has stopped working.On checking the Applet console , code execution seems to be smooth till the following
com.asprise.util.jtwain.Source source.acquireImage()
There is no exception being thrown as well. Also , jar signing has also been done (Though there is another application that works superbly even without this).
Any advice would be highly appreciated.
This is my first question on the forum , kindly excuse if there had been any non-compliance with standards.
To troubleshoot the issue, you may test with the JTwain web demo on your Windows machine to see how it works.

Did anyone encounter an error with ASP.NET debugging? I've made a really simple, empty MVC page, I've tried returning /Home/Index.cshtml and a string, and each time I get a windows jingle and the browser can't find the server. It doesn't happen when I run it without debugging though, then the website runs just fine.
I've also tried the default MVC template, with Bootstrap etc, and it's the same - runs without debugging, doesn't run with debugging.
It's probably important: I'm running Visual Studio 2017 on up-to-date Windows 10. I've reinstalled the system several weeks ago, really wouldn't want to do that again :/
Generally we could debug an app with the normal user, but sometimes we need to use the admin, for example, as far as I know, if we want to use the attach to process tool for remote debugging, we often run the VS as the admin or others.
This document share us the tasks we need administrator permissions to completeļ¼

If possible, you could refer to it especially "Debugging" area in above link.
Hope it could help you:)
I've recently inherited a task at my company that involves implementing an application that has currently been running off an employee's windows desktop, and migrating that code to Unix Server used for the office.
The server also runs IBM's websphere, which contains many of the companies larger web applications and uses java 1.6.
Organizational points aside (this is a huge company and much of the coding looks like a spaghetti western, with old legacy systems I wouldn't be suprised if people don't have any idea about), my plans was simply downgrade the code (which was simple as it was from 1.7 to 1.6), then move this application to a runnable jar, and call it via a shell script.
I, however, realize now why this application was never migrated to our production server, as I can't get the thing to run in the UNIX system.
First, I ran into an issue where (and I may be wrong about this) the SSL connections used as part of the application throws an error (same error as this question: Error accessing a Web Service with SSL) After some reading, it seems that any java application run on a server with Websphere (if the application is not in websphere) cannot be done, and thus you have to manually set some java Security Properties to do this (which i did right at the opening of my main method).
After doing that, I get past the initial error, but I am now getting this error
"com.ibm.jsse2.util.j: PKIX path validation failed: java.security.NoSuchProviderException: no such provider: IBMCertPath"
If this has already been asked, I'm sorry, but I couldn't seem to find it. Please link it here and i will close the question.
You are getting the error because something has specified to use the IBMCertPath provider, but java security doesn't know what that provider is.
You need to ensure that com.ibm.security.cert.IBMCertPath is in the provider list in your java.security file. See:

I have an issue on exported build release from Flash Builder 4.6. The case is when I run it on the IDE(Flash Builder 4.6) it works fine, no issues encountered, it never crashed but when I exported it for a release build and run, it crashes to a certain module/view. The view/module where the AIR app crashes has multiple remote object calls (minimum of 5). I have noticed that when requesting multiple remote object calls(like 5 remote calls at a time) it crashes. Is the remote object causes the crash? Please help me out on this guys, any idea will be much appreciated.
Thanks
Glen
I bet it's a security issue that you worked around when invoking the application from the ide. By default, Flash Builders working directories are marked as "secure", so you don't get any security issues. But when working on the live system, you might need to have a corssdomain policy.
Also: i suggest to use the Thunderbolt logger with the logging framework. This allows you to get log informations straight into your browser's console.
In my asp.net application, I am using Aspose.PDF for merging 2 pdf documents. I get the PDF documents from a third party tool and then merge using Aspose.
Problem is when I am running the solution, it works fine, but when I publish the solution and then run it from IIS, it gives me the error: "Error getting authentication ticket."
Please help. If any other details are reqd, pls do let me know.
Thanks.
Are you running the application is full trust mode? The Aspose.Pdf for .NET only works in full trust environment. Please see the details here: http://www.aspose.com/documentation/.net-components/aspose.pdf-for-.net/declaration.html. Please make sure that you deploy the application in full trust environment.
Disclosure: I work as a developer evangelist at Aspose.
I have one web application. while i debug the solution the rendering makes too slow and if i close the browser page i got one error like this
WebDev.WebServer.exe has encountered a problem and needs to close. We are sorry for the inconvenience.
I got one information from attched proess is that this .exe file related to asp.net development server- port(port number).
How it can be resolved? please help me..
You cannot close the browser that opens when you are running debug for an ASP.NET program.
It renders slower because you are debugging it. This means the compiler has injected a lot of extra code need to make the application work with the debugger. There is no getting around this.
