java - How to install J2ME .jar files in remote devices without pairing? -

-

I am developing a J2ME application to run in public areas, such as supermarkets, shopping centers, etc. Therefore, I want to make it possible to set up my application in every mobile phone around Bluetooth. I intend to create a separate J2SE application to search for a device and view the obex services. After that, ask the user to install the application.

I have tried using javax.microedition.io.Connector, but it always requires both side (client and server) passkey 

  OBEXClientSessionImpl conn = (OBEXClientSessionImpl) connector. Open (service URL);

I have also found what I want, but pair problem persists.

Can you definitely send files to a program via Bluetooth or use a fixed pin number, so I can not repeat it on the server side?

Thanks in advance,

I used to use Nilekov in the same way Has developed a Java application that shows you (scan and attempt to transfer file on all devices) and worked fine on initial tests. I'm considering midterm to open or sell the device in the future.

To answer your question, which I use (simplified version) is something like this: 

  // tud: Scan for devices // @TODO: Obex push service string tool for detection of each device, Obex url = service records [i] .getConnectionURL (service record. Nyuthentic doanrrrp, incorrect); // send the file client session client session = (client session) connector.open (deviceboxes url); Headset hsConnectReply = client session. Connect (tap); If (hsConnectReply.getResponseCode ()! = ResponseCodes.OBEX_HTTP_OK) {return false; } Byte data [] = readAllFile (file); Headset Set TopSets = Client Sessions .createHeaderSet (); HeaderSet.setHeader (headerset.name, file.getName ()); HeaderSet.setHeader (headset.tepie, mimetype); HeaderSet.setHeader (HeaderSet.LENGTH, new long (data.length)); Operation session = Client session. Input (headset); OutputStream Output Stream = op.openOutputStream (); // @TODO: Write all data and close output streams, sessions and client sessions

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...
