Java Result: -1073740791

[PreethiGowri]

Can somebody explain me what does Java Result: -1073740791 mean. I had a code which used to send data that was saved in my mysql database, through ethernet using UDP protocol, everything worked fine until i sent fewer data(25 rows), when i started sending data in huge amount(100 rows) it used to display Java Result: -1073740791 and would stop the running code. Im using jpcap, winpcap and netbeans.

Find out where exactly that message comes from. If it's from one of the third party APIs' method then check it's specs to see when such errors could be reported.

[PreethiGowri]

while(rs.next()) {
               outData.append(rs.getLong(1)).append(":")
.append(rs.getString(2)).append(":").append(rs.getInt(3))
.append(":").append(rs.getString(4)).append(":")
.append(rs.getString(5)).append(":")
.append(rs.getString(6)).append("$");
           }
           outData.append("#");
 

/*datatypes in java and mysql

java mysql
getString varchar
getLong Bigint
getInt int, tinyint */

the error occurs after this ResultSet block, , i dont know why

[r035198x]

You can pinpoint it further by putting those rs.getXX calls in separate statements. If it's the bigint column then use try using getBigDecimal.

[PreethiGowri]

i tried doing it by sending 25 rows of data per 1 iteration of for loop and it works fine. But when i try to transmit whole set of data its not working, it gives the same notification(Java Result:-1073807364).

Is their any limit for ResultSet?!

[r035198x]

What do you mean by transmit? Where did you set the limit?

[PreethiGowri]

i transmit the accessed data from database to an other system via ethernet.

i have set the limit here -

String query = "select * from table_name limit "+limit1+",25";

where, limit1 holds values like 1,26,51 and so on

[r035198x]

Maybe you are keeping the database connections open for too long while doing the transfer? Select the data into a List of results and close your result set and connection then loop through your list transferring the records.

[PreethiGowri]

I tried that too, without any success :(

[r035198x]

You now need to create a small but full complete class with code that demonstrates the problem and post it. If the error is database side only like you are suggesting by saying it's affected by the limit then the example code shouldn't need to include the part that transfers the files.

[PreethiGowri]

I have attached the whole working code part causing the problem, please find the attachment.

[r035198x]

No don't attach all the code. Create a small class with code that demonstrates the problem and post that code here using code tags.

[PreethiGowri]

public static String getData(String table) {

            outData.append("~"); //the code terminates at this line
            rs.close();
 
            con.close();
            System.out.println(outData);
        } catch (ClassNotFoundException ex) {

        } catch (SQLException | RuntimeException e) {
            JOptionPane.showMessageDialog(null, e);
        }
        return outData.toString();
    }

Here it is

[r035198x]

Don't just do

} catch (SQLException | RuntimeException e) {
            JOptionPane.showMessageDialog(null, e);
        }
 

when debugging. Print out the whole stacktrace with e.printStackTrace();

[PreethiGowri]

i see some errors in log file after printing the StackTraces, i don't understand what they actually mean, kindly help me.

Here i attach my IDELog file

[r035198x]

Post the error messages here, don't attach files.

Most of those are info messages from your IDE that have nothing to do with your application. Put the e.printStackTrace() in the catch blocks and check your application's console to see what the full error message is from your application.

[PreethiGowri]

i get no error in my console. This is my output

[r035198x]

Why is your program printing out all that data? Anyway you need to pinpoint the source of the problem (if any) perhaps by running it outside of Netbeans because right now you seem to be confused about what is Netbeans' own logging and what your application's logging is.

[PreethiGowri]

i got the below lines printed from the printstacktrace -

java.lang.NullPointerException
at dao.DAO.getBay(DAO.java:79)
at pkgnew.New.sendBayNo(New.java:252)
at pkgnew.New.receivePack(New.java:322)
at pkgnew.New.main(New.java:495)

where line 495 as:

 j.receivePack();

how do i avoid null point exception here?!

[r035198x]

So what code is at DAO.java:79? Something there is null.

[PreethiGowri]

 String query = "select * from table_name";
            System.out.println(query);
            PreparedStatement st = con.prepareStatement(query);

line 79 is preparedStatement

[r035198x]

So con is null at that point then.

[PreethiGowri]

I resolved the null Pointer exception. now again i get "Java Result: -1073740791" and the code terminates:(
After googling alot i learnt that, The number "-1073740791" is an exit code, which indicate a bug in the executed software that causes stack overflow leading to abnormal termination of the software.

If this is the actual case, how do i avoid stack buffer overflow??

[r035198x]

Again, add logging around the code and e.printStackTrace statements to pin point the exact line that is causing it and full error message.

[PreethiGowri]

i have used this below block, still does not show up any warning or error at any line

catch (UnknownHostException ex) {
            Logger.getLogger(New.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException|RuntimeException e) {
            e.printStackTrace();
        }

[r035198x]

1.) How do you know that is the line that is reporting the error?
2.) Add e.printStackTrace() before Logger.getLogger(New.class.getName()).log(Level.SE VERE, null, ex); during this debugging (you can remove it after you identify the source of your problem)

[PreethiGowri]

Not Working:(:( I have completely lost with this, i'm going nuts tracking the reason behind this abnormal termination of the code:(

[r035198x]

You still haven't said whether you have pinpointed the source of the error using printlines and printstacktraces yet. You need to know the exact line that is throwing the error first.

[PreethiGowri]

Well, yes i have used printstacktraces and printlines. The code exactly terminates when i try to send the data, after packetizing it. This is the code line

 sender.sendPacket(sendPacket);

where sendPacket is the byte array that holds the data packet.

[r035198x]

Did you wrap just the sendPacket call in a try/catch then?
What does the documentation of the sendPacket method say? Did you write it or is it part of some third party A.P.I

[PreethiGowri]

yes, i did wrap the code line within a try catch block, Its a part of third party API of this " UDPPacket sendPacket = new UDPPacket(55000, 61000);"

here is the code snippet of what and how i'm doing,

try {
                InetAddress src = null;
                InetAddress dest = null;
                if (pack instanceof IPPacket) {
                    IPPacket ipp = (IPPacket) pack;
                    src = ipp.dst_ip;
                    dest = ipp.src_ip;
                }
                EthernetPacket etherSrc = ((EthernetPacket) pack.datalink);
                byte[] gwmac = null;
                gwmac = etherSrc.src_mac;
                System.out.println("dest mac : " + gwmac);
                JpcapSender sender = JpcapSender.openDevice(devices[index]);
                UDPPacket sendPacket = new UDPPacket(55000, 61000);
 
                sendPacket.setIPv4Parameter(0, false,                             
                    false, false, 0, false,
         false, false, 0, 1010101, 100,
         IPPacket.IPPROTO_UDP,
                        src, dest);
                String outData = DAO.getBay(bay);
                sendPacket.data = outData.getBytes();
                EthernetPacket ether = new     EthernetPacket();
                ether.frametype = EthernetPacket.ETHERTYPE_IP;
                ether.src_mac = devices[index].mac_address;
                ether.dst_mac = gwmac;
                sendPacket.datalink = ether;
                System.out.println("back to sendbay");
 
                try{
                sender.sendPacket(sendPacket);
                }
               catch ( RuntimeException ex) {
                ex.printStackTrace(System.out);
                Logger.getLogger(New.class.getName()).log(Level.SEVERE, null, ex);
            }  
            }
            catch (IOException ex) {
                Logger.getLogger(New.class.getName()).log(Level.SEVERE, null, ex);
            }   

[r035198x]

Don't do

catch ( RuntimeException ex) {
                ex.printStackTrace(System.out);
                Logger.getLogger(New.class.getName()).log(Level.SEVERE, null, ex);
            }  

Then check the APIs for those external classes as well to make sure you're calling them with right values.

Just do

catch ( Exception ex) {
                ex.printStackTrace();
 
            }

From what I understand, the problem is occurring because your max heap size is being exceeded during some processing event - be it in the development kit or while emulating. The good thing is that you can alter the max heap size in the android.ini file (it's at the very end.) I changed mine to 1024M.
