Hello, I've developed a B4J application that is distributed as both JAR file and a Windows Packaged (portable) application. After some user reports, I've tested the executable at https://www.virustotal.com/ This is the result. Is this something to be expected? How can I prevent this?

So, I have built a jar file named PrintPageReportWrapper.jar that I can execute from a command line with java -jar PrintPageReportWrapper.jar. Unfortunately, I have never had to go beyond this point in my java development other than deploying the jar file to desktop computers. I am now trying...

Hello, Some strange is happening, I can't figure out what, it must be something very small or it is a bug. I have a few buttons,which are to do something else, but I misuse them for now to figure something out. Strange thing is that I get errors depending on who knows what. I'm just testing...

Hello, a customer tells me: "I have a fingerprint reader that only comes with an .ocx library and I want to use it". With B4A and mainly with B4J can I make use of the library? How? Thank you.

The question that has been on my mind is whether Earl Uzil developed b4a and b4i with b4j? 😂😂 If so, what is b4j developed with?🤣 Didn't the server write the same site with b4j?😍😅 Really, why is the b4a tag not so popular in StackOver Flow and it can not be used in posts?🙂
