EXCEPTION_ACCESS_VIOLATION

i have an application which receive data from serial port and send it to the database , but an exception occurs and i don't know what does it main so the following is what i received at the saved file which is result from the exception:

In your case it is probably caused by one of the third party jni/dll libraries you are using, either odbc or serial.

Probably serial.

You can solve it with one of the following.

1. Find a different 3rd party library.

2. Determine exactly what sequence causes the problem. Then find a different way to do that.

actually i used both of them,,but i have to mention that i tried run the program without database it runs well,but when i used database this exception is occured.

Then the problem is in the odbc driver (which is not the same as the jdbc-odbc bridge.)Again you can track the problem down and then work around it.

And that has nothing to do with it.

I didn't say that the driver didn't work at all. What I said was that some particular bit of functionality that you are running is causing it to fail.

If you did that functionality a different way with the same driver then it wouldn't fail.

(I might note that the "same" driver on a windows system doesn't in fact mean that you are using the same driver. You can only confirm that by checking the dll versions.)

> MY CODE:

Useless.

The VM is crashing. That means it has NOTHING at all to do with java code.

i have counter same problem. i do some data query using odbc inside thread. so i counter the problem by slowing down the process by putting for loop or allow the thread to sleep for a while.horah~
