问题 In Java, what would the best way be to have a constantly listening port open, and still send upon receipt of a packet. I am not particularly savvy with network programming at the moment, so the tutorials I have found on the net aren't particularly helpful. Would it make sense to have the listening socket as a serversocket and run it in a separate thread to the socket I'm using to send data to the server? In a loosely related question. Does anyone know if programming simply for java, in

问题 What are the key differences between Android, iOS and Blackberry OS in terms of level of accessibility by application developers (i.e. access to the video input, sound input, phone functionalities, to which extent, etc.)?

问题 My application screen looks similar to the image attached. I have multiple rows and each row has a Bitmap image, title and description field. All the information's are getting fetched from our supporting web-server in the form of XML.

问题 Every indication I have, based on my experience in embedded computing is that doing something like this would require expensive equipment to get access to the platform (ICE debuggers, JTAG probes, I2C programmers, etc, etc), but I've always wondered if some ambitious hacker out there has found a way to load native code on a Blackberry device. Anyone? Edit: I'm aware of the published SDK and it's attendant restrictions. I'm curious if anyone has attempted to get around them, and if so, how far

问题 I've installed Blackberry Java plugin 1.3.0. When I create a new project BlackBerry_App_Descriptor.xml shows error. What is the problem? Is there any environment path problem? If yes, what should to set path? 回答1: InvalidRegex: Pattern value '([a-zA-Z_]{1,63}[\s-a-zA-Z_0-9.]{0,63}[;]?)*' is not a valid regular expression you should of course follow the hint in the error and check that none of your values in your BlackBerry_App_Descriptor.xml will fail the regex.
