问题 I've created an applet that uses JavaPOS to communicate with a payment terminal on the user's local system. When run from within the Eclipse IDE, the applet works fine, but not when run in a browser. In a browser, the applet can't seem to find the jpos/res/jpos.properties and jposxml.cfg files. When the following statements are executed in the applet (in the start() method, not init()): JposEntryRegistry registry = JposServiceLoader.getManager().getEntryRegistry(); registry.load(); this is

i am searching for a solution to print to an Epson POS Printer from Android devices and any kind of help is needed. So am i right that JavaPOS in this case is the right solution? I found this example JavaPOS Hello World in Java . So i guess i somehow have to create the printer connection and then use JavaPos to send the specific commands? Does anybody have any experience in doing that and can give me a little help in starting with this? Thanks a lot in advance! I don't believe any printer companies have JavaPOS utilities for Android at this time. In my experience, it's best to use an API

问题 I'm new to JavaPOS. I wanted to create an online Java POS application that uses JavaPOS. Is it possible to access the POS peripherals regardless of the brand? Is it possible that Epson ADK will be enough to access the other brands too? And more importantly, can it be accessible via web? How do I start coding in JavaPOS in Eclipse? I found a paper about deployment (JavaPOS deployment), but it doesn't say anything about development. I also found some examples but I do not know how to set it up

I would like to print a sample line on my USB POS (Point-Of-Sale) printer from a java program on Windows XP. I tried to setup a JavaPOS implementation but I get exception after exception for a missing jpos.xml or missing javax.usb.properties file. Can anyone tell me how to generate those files? They somewhat need to link to an implementation or something like that and I'm not sure what the (rare, unclear and incomplete) documentation means. Any other help would be appreciated. My current printer model is Star TSP 100 with a USB connector. My printer seems to be connected correctly since I can

问题 I've implemented a Java package with functionality to operate a POS printer and cash drawer connected to the workstation via USB. I've also implemented an applet to utilize the functionality of this package with the hopes of having it invoked by a POS website. When the applet is run from within Eclipse, all goes well. When the applet is run from within a browser it seems that my package is unable to access the peripherals connected via USB. I get an error from the third party (JavaPOS) code
