browser executing local file - repost2-Publisher/Signed Certificate

Tech skills required: Java or another programming language that can access the user’s file system from a web browser, specifically Chrome. Platform: Chrome browser running on Windows XP, Vista, or 7 applet (Java?) must be allowed to open from Chrome web browser. We have an executable that can open a cash drawer connected to the user’s computer by usb. We need an app (Java?) that can be run from the browser that can access the user’s file system and run the executable. The app must be written in a way that it can be executed on demand from a web page using javascript (or PHP). The user should not be required to click a button to execute the app. The app should first check for the presence of the attached [login to view URL] file in a specified directory (C:\BIT\CASH\). If not present, it should return a message. If the file is present, the app should execute the file. The app will likely need to be signed and allow the user to be warned that the app will access the file system and be given the option to run or cancel. REPOST #1 Original project completed a well-working Java applet, but the latest Java update (21 or 25) is causing the applet, [login to view URL], to display a Block/Don’t Block prompt – there is no option to turn off the prompt. I did some research and found that there is a work around; details are in the link below. We need someone to update the applet to make it work well again. [login to view URL] REPOST #2 Java pushed another update that is causing permission windows to open when the cash drawer java app is used. [login to view URL] • Starting with Java 7 Update 40, the option for Do not show this again for this app is no longer available. Unlike previous versions, the user cannot suppress the security dialog for an unsigned application and will have to select the option, I accept the risk and want to run this app, each time the user wants to run an unsigned application. I think the application must be signed and the manifest must include the Permissions attribute.
