Java Forum / General / June 2005Redirect Standard output to keyboard port
I have written a Class, that reads from a COM-port. I have a tag-reader attached to my COM-port, and I want to write the ID of the readed tag into whatever application I want, for example notepad. Not just as an output on the running program. That means, I will run the "Reading-application" in the background. And every time a tag is read, the output goes to the aplication having focus. Just like a keyboard. Anyone have an idea. I have made the part reading the tags, so it is just the redirection that I need help for... Jim > I have written a Class, that reads from a COM-port.

Just like a keyboard. Anyone have an idea. This is quite platform-specific, so I doubt you can do this in Java natively. For example, if you log in to a server via SSH (or remote desktop, or some other remote access tools) then you'd probably not want the input to come from the "keyboard", but from whatever source the "normal" input is coming from. For some programs, this might be "standard input", but not for the ones interfacing with the "input" in a more low-level way (such as most text editors). You might want to have a look at JNI and write some platform-dependent code. It is probably much easier to generate the output in your program, and copy it to the clipboard (or X buffer or whatever). Not exactly what you asked for, but maybe that's an alternative. Greetings, Aaron This application will run on Windows XP or Windows 2000. And it doesn't matter if it is platform dependent. It should be used to load text into an applet. And since the applet can't interact with the local COM-port I have to think of other solutions. Anyone have an idea?

Which libraries does the applet use? Is it the local libraries on the client, or th libraries on the server, in which the applet reside? Doesn't the applet have limited access to the client? > I have tried to use the class from an applet, but my knowledge of > applets is limited. > Which libraries does the applet use?
