Java: app crashes during connecting GSM USB modem

Question

Java: app crashes during connecting GSM USB modem

I am working on an open-source application called FrontlineSMS which can be interfaced with GSM modems to send and receive SMS. The windows installer that is available through their website works fine. Since i wanted to modify it, I got the source code and built the jar and tried to launch it. When I plug in the GSM modem and launch the application, it sometimes detects the GSM device and i am even able to send and receive SMS. Or else 1.) I get the following error-

2.) OR the application sometimes crashes by creating a log file which contains:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) means access denied in windows, usually because you don't have permissions/rights to do what you're trying to do.

Your built jar likely needs to be signed to access the drivers. This tells the java runtime that it's ok to access system drivers, the filesystem, etc.

Here's a tutorial: http://java.sun.com/docs/books/tutorial/deployment/jar/signing.html

We'd have to see the code, not just the error in termios.c. Most likely, there is an error in the native library that is called from Java. An Access Violation error typically occurs when you try to access a variable in memory that has been freed.

I got the same problem as you, my solution was quite simple, i was using a USB-Serial Cable, the cable was a bad one, I just replaced the cable for a better one with a different driver, problem solve. The RxTxCom driver was having issues getting UART from the "PORT", thats why is crashing, here below the solution found some place else:

Thats the line number. SetupComm failed.

termios.c(869):

     if( !SetupComm( port->hComm, 2048, 1024 ) )
     {
             YACK(); <===== 869
             return -1;
     }

SetupComm is a very old w32 API call so there is something unusual about the port.

YACK() is a helper macro that just spits out why the call failed. "Yack, yack, yack!" :)

My guess is that is not a real serial port but rather a driver trying to look like one [poorly]. A 'real' serial port has a UART and is typically recognized without additional drivers. There isn't anything we can do to improve that function call from what I can tell. You may look to see if there is a newer driver for the 'serial port' if what I said makes sense to you.

The only other thing I can suggest is that you don't want any other software using the port while you try to find it with rxtx.

Hope it helps you out.
