Stop Threaded stream reader reset

I have been trying to create a threaded search for looking through a comma delimited text file for a certain string section. The search uses a custom input stream reader which is currently declared in the thread class. The search works however I want to be able to find the next search result from the file. Obviously if I run the thread again the stream is reset to the start so my question is how do I declare the stream so it carries on from the previous position. Im thinking I have to declare it in a seperate class or something but am unsure, thanks for the help in advance.

I am not quite sure why you mention that it is a threaded search. I just cannot imagine how and why you would go about and search through an InputStream with multiple threads, so I assume you are just plain searching in an InputStream and this just happens in a separate thread from main.
Why is it that your custom InputStreamReader is reset when the thread is started? You seem to have full control, so just don't restart it. Make sure that the object is not just a field in the thread object that most likely is dismissed when the run() method terminates. Or just keep the thread object in a variable and reuse it instead of creating a new one when you want to restart the thread.

IOException: Connection reset by peer: JVM_recv in socket input stream read

hi
I encountered a problem : a program throw out an exception:java.io.IOException: Io exception:
Connection reset by peer: JVM_recv in socket input stream read.
I tried my best to resolve it ,but unfortunately,i didn't know what caused the exception.
the following is my application environment:
I have two PC(Win2000os),one is a server which installed oracle9.2.0.2 and jdeveloper9.0.3,the another is a
client which only intalled jdeveloper9.0.3.Two days ago,i performed a web application on my client with
jdeveloper,and it includes some JSP and a javabean files.JSP Page finished uploading client xml file to a
folder on server and the javabean finished loading the xml file into a xmltype column.I can make sure the
connection is established and the javabean is OK,beacause my some jsp page can successfully use
<jsp:usebean> tag and use the javabean's some other public interfaces,except the interface that finishs
loading the xml file into a xmltype(clob) column.
Then i do many tests!I changed the javabean to a java class incluse a main method beacause it is easy to
debug.Finally i found the following code caused the exception:
public CLOB writetoClob( CLOB clob, InputStream is )throws SQLException, IOException {
InputStreamReader reader = new InputStreamReader( is );
Writer writer = clob.getCharacterOutputStream( );
char[] buffer = new char[clob.getChunkSize( )];
int charsRead;
for ( charsRead = reader.read( buffer ); charsRead > -1;charsRead = reader.read( buffer ) ) {
writer.write( buffer, 0, charsRead );
writer.close();
return clob;
when it runs to writer.close(),the exception is caused!
Then i copy the java class to the server,it runs ok!
That is to say ,the same code,the different result!
But when i run my web application on server with jdeveloper Embedded OC4J Server and a jsp page loaded javabean
and run to mentioned code ,the same exception occured!
I checked the application log in event viewer,the descriptions was:
The data buffer created for the "AppleTalk" service in the "C:\WINNT\system32\atkctrs.dll" library is not
aligned on an 8-byte boundary. This may cause problems for applications that are trying to read the
performance data buffer. Contact the manufacturer of this library or service to have this problem corrected or
to get a newer version of this library.
I search some some resolution about this exception with web and someone sayed :
This basically means that a network error occurred while the client was receiving data from the server. But
what is really happening is that the server actually accepts the connection, processes the request, and sends a
reply to the client. However, when the server closes the socket, the client believes that the connection has
been terminated abnormally because the socket implementation sends a TCP reset segment telling the client to
throw away the data and report an error.
Sometimes, this problem is caused by not properly closing the input/output streams and the socket connection.
Make sure you close the input/output streams and socket connection properly. If everything is closed properly,
however, and the problem persists, you can work around it by adding Thread.sleep(1000) before closing the
streams and the socket. This technique, however, is not reliable and may not work on all systems.
In general,the following information is conclution:
Web application runs error both on client and on server.
If it was changed to a client java class,it only run ok on server!
i have done anything that i can do now,i feel depressed very much!
how can i resolve the problem!
Any a little help will be appreciated!
regards!
Thanks

JDBC Connection reset by peer: JVM_recv in socket input stream read

Hey Guys,
Has anyone seen this issue? We get this error in our Weblogic app logs at times and no one is able to login to our application. Our database server and SQL server seem fine at a high level. Any ideas what is causing this?

please make sure that there is no Firewall between your servers and DB server. this message usually happen when there is a fire wall between the servers. if yes please make sure that the connection time on fire wall is longer than the time needed to complete an operation another thing that you need to check if you have a fire wall which is to make sure that Oracle DBMS return the request to the same port that it is listening to (1521 default).

Io exception: Connection reset by peer: JVM_recv in socket input stream read

We are developing a new J2EE app using JDev, OC4J, servlets, and EJBs. We have determined that our firewall is closing database connections that have been idle for 1 hour. This is a security requirement that cannot be changed. When we try to use these idle connections in both stateless and entity beans, we consistently receive this or a similar error message:
"ServletSACategoryList: Error invoking EJB procedure. Exception: java.sql.SQLException: StatelessSysAdminBean::getCategoryList - Io exception: Connection reset by peer: JVM_recv in socket input stream read "
Environment:
Oracle 9iAS 9.0.2.0.0
Database: Oracle 8.1.7
JDBC 8.1.7

JDev 9.0.2.829
We are using the ejb-location attribute within data-sources.xml for JNDI lookup of the DataSource. Here is what this file looks like:

After calling getConnection() on the Connection object in my stateless bean, I have tried checking if the Connection object is null or isClosed(), I have caught any Exception, and looped to try again, but nothing has worked.
Please respond to [email protected] or directly to this post if you can help in any way.

Hi Robert,
If you don't mind, I can only offer a few suggestions for things
to try -- I'm afraid I don't have a solution for you. Of-course,
you may have already tried these things, so please excuse me if
this is the case.
Firstly, your "data-sources.xml" file looks "different". Have
you read the "Data Sources" chapter of the "Oracle9iAS Containers
for J2EE Services Guide, Release 2 (9.0.2)"? It is accessible
from here:
http://otn.oracle.com/docs/products/ias/doc_library/90200doc_otn/web.902/a95879/ds.htm#1004903
Also, have you tried running OC4J in "debug" mode? This web
page has more details:
http://kb.atlassian.com/content/atlassian/howto/orionproperties.jsp
I get the impression from the information you have supplied,
that you may not be explicitly closing your database connections
in your code. It looks to me like you are obtaining a database
connection in your session bean, and then keeping it for the
lifetime of that bean. Is that correct? I think it's better
to obtain a connection when you need to interact with the database,
and then close the connection immediately after completing the
interaction with the database (but that's just my opinion).
Lastly, if you haven't already discovered them, these web sites
may also be of help:

http://www.orionsupport.com

Hope this helps you.
Good Luck,
Avi.

Connection reset by peer: JVM_recv in socket input stream read

Dear All,
We are facing a very unusual problem. In our application, there is a functionality to transfer files to a FTP server using java FTPClient.
Now while transferring set of files, few times it throws the error:
Connection reset by peer: JVM_recv in socket input stream read
This error comes irregularly.
Can you suggest the reason for this.
Regards,
Akhil

which platform are you using? which ip stack , ipv4 or ipv6?
try to set -Djava.net.preferIPv4Stack="true" when startup,
it will use ipv4 stack instead of default ipv6 on solaris.

SocketException during reads - JVM_recv in socket input stream read

I am getting a SocketException when a Java applet talks to our
WebLogic 7.0 server. The catch is that it only occurs at one site
(that has very high T1 utilization, although latency is only ~60 ms)
Our setup is such that the calls hit an Alteon load balancer, which
then sends the request out to one of 4 IIS clustered servers, where it
then is sent to one of 2 WL clustered servers. I figured latency
would be the cause, but on IIS and on WL, the timeouts are set to
several hundred seconds, so I am not quite seeing where the connection
is being reset. To be honest, I really don't know if it is WL that is
killing the connection, as nothing abnormal shows up in the WL log. I
have seen similar problems in this group, though, although the stack
traces never follow the same path mine does. I do have the following
call stack from the Java plug-in console, though. Any ideas would be
greatly appreciated.

I'm getting the exception on the client, which is an XP machine, while

Connection Failure: ReadFile on fd=1231 failed with err=64 + JVM_recv in socket input stream read

Hi Guys,
Using weblogic 5.1 (downloaded pretty soon after announcement) on windows
2000 (yes I know not certified there yet) and using jdk1.2.2-001.
I have a pretty standard setup - a connection pool (5) to a sqlserver
(remote) machine.
A pretty standard multithreaded servlet - grabs a connection, does a select,
calls dbkona to dump output, releases connection.
It runs fine - browser returns result. When I push 'reload' on browser, say
10 times very quickly, I get the following errors. It is sometimes a
combination of these:

Now I can get rid of (1) by switching off native IO!! This also stopped IO
exceptions that were being raised by the servlet when it tried to output to
the output stream. (2) persists.
I have changed nothing else in the properties.
(1) sounds like I may need to up the number of file descriptors open?
(2) I don't know. Is my server too loaded? I am running on a 600Mhz using
64Mb heap for the server with 300Mb swap available...

Unable to stop browser streaming to the server

Hi All,
I am having a problem when using apache fileupload framwork. However I don't think it has to do with this framwork. It's more general upload issue.
When I upload a file I do the check for its size. I am streaming the request from the browser. If the file gets to large I stop the streaming by closing the streams including the ServletInputStream. Still the browser streams to the server. While my response is ready to be returned to the browser. And is returned when the stream is ready. I think you need to stop the SocketInputStream somehow. I am trying to find out on how to do this. Any suggestions are welcome.
By the way if close the browser early I get java.net.SocketException: Connection reset
I am using Websphere Portal. But any example with other server in portlet or non portlet context are okay too.
Does anyone know a solution to stop the portal from reading the request? In other words stopping the browser from streaming to the server?

Is there any missing features in your server, see here for mitigation-

Re: Connection Failure: ReadFile on fd=1231 failed with err=64 + JVM_recv in socket input stream read

Jon,
I believe that this error is similar to a "connection reset by peer". It is
a Window specific error. I believe it indicates that something has happened
on the other end of the socket such that the socket has gone bad.
I think that this should only occur when people reset their connection
before the reply is sent. I don't believe that it is indicative of any
serious problem other than this communication failure caused by the client.
I've opened an issue to catch and squelch these spurious exceptions rather
than logging them. For now I think it is safe to ignore them.

Hi Guys,
Using weblogic 5.1 (downloaded pretty soon after announcement) on windows
2000 (yes I know not certified there yet) and using jdk1.2.2-001.
I have a pretty standard setup - a connection pool (5) to a sqlserver
(remote) machine.
A pretty standard multithreaded servlet - grabs a connection, does aselect,
calls dbkona to dump output, releases connection.
It runs fine - browser returns result. When I push 'reload' on browser,say
10 times very quickly, I get the following errors. It is sometimes a
combination of these:
1- Mon May 08 13:34:41 GMT+00:00 2000:<E> <HTTP> Connection failure
java.net.SocketException: ReadFile on fd=1912 failed with err=64
at weblogic.socket.NTSocketMuxer.initiateIO(Native Method)
at weblogic.socket.NTSocketMuxer.read(NTSocketMuxer.java, Compiled
Code)
2- Mon May 08 13:40:42 GMT+00:00 2000:<D> <ListenThread> Problem
accepting connecti on java.net.SocketException: Connection reset by peer:
JVM_recv in socket input stream read
Now I can get rid of (1) by switching off native IO!! This also stoppedIO
exceptions that were being raised by the servlet when it tried to outputto
the output stream. (2) persists.
I have changed nothing else in the properties.
(1) sounds like I may need to up the number of file descriptors open?
(2) I don't know. Is my server too loaded? I am running on a 600Mhzusing
64Mb heap for the server with 300Mb swap available...
Regards,
Jon

We are seeing the same error since switching to sp11 (we had been using

I have no idea as to the cause. It's been posted in the archives before -but with
no particular solution.
I'm using WLS 5.1 SP11, JDK 1.2.2_007. Win2000.
Does anybody know the cause/solution?
Thanks.

Hi,
I have noticed that applying the service pack helps things quite a bit.
I no longer get NT muxer errors etc etc. just the "connection reset by
peer"
every now and again.
As I am repeatedly hitting the server from one browser, your 'connection
going bad' scenario probably
applies quite well.
(btw. before the SP, the errors seemed to crop up more just before/during
a
GC.)

As a guess what you are doing with that zip stuff is very odd.
You do realize that it is just going to put some binary data into the blob right? And the methods that is going to use will not necessarily create a 'complete' zip file?
If you want a zip file then just load the file, dont use the zip classes.
And if you want part of a zip file, (and want to store the parts as a zip) then extract it from the file and create another zip entity using a byte stream rather than a file.
Finally I suspect your error with the blob occurs because you do not close the statement. But at any rate you should figure out how to do the blob code independent of the zip stuff.
And what oracle driver version are you using? Some of the older ones need oracle specific handling for blobs.

Stopping threads

how to stop threads immediately?following is my threading code.when i press the stop button the game stops after one or more generations (John Conway's life game).i have tried the boolean solution i.e. declaring a boolean variable and setting it true or false to start and stop the game.is there a more powerful method than yield to stop the thread?how to solve this problem?
private Thread lifeThread=null;
//this is the code used when the start button is pressed
public void start() {
if(lifeThread == null)
lifeThread = new Thread(this);
lifeThread.start();
//this is the code for the stop button
public void stop() {
if(lifeThread != null)
lifeThread.yield();
lifeThread = null;
//run method
public void run() {
while (lifeThread!=null) {
next();
gen_num++;
repaint();
try {
lifeThread.sleep( delay );
} catch (InterruptedException e){}

no.....thread.stop() is not a good read for your question....ignore the last poster.
You have the right idea...you simply need to set your boolean in a finer grained way. If you are in a long loop, then you should be checking that boolean value at the top of your loop so you can drop out of the loop immediately when the user requests to stop it.
So again, right idea, you just need a minor logic change.

Stop/Start Streaming Mp3 Sound- Button Script

I'm looking for a button script to stop a streaming mp3 sound

click and so on.

You need brackets after the function call...

Multi-thread file reading

Hi,
I've got a tricky question: I have to read large files (over 150 MB) - I found here several topics about reading such a large files, but all examples were about single-threaded reading from file... Do you think, multi-threaded reading would be faster? I am in quite a dilemma: multiple threads in general means faster processing, but in this case, all threads are reading from the same source/file
(I use javax.mail.util.SharedFileInputStream for multi-threaded file reading - each stream in separated thread)
so what do you think, which is faster: single-thread or multiple-thread? and if so, how many threads would be fine - 2, 3 or 4?
thanks a lot

The I/O thread processing thread(s) approach will work when the processing takes more time than the I/O (i.e. when the medium can transfer information faster than a single thread can process it).it is very likely that processing will take more time then file reading - there will be 5-7 regex to match per line, sometimes object creation and filling object fith some data
so it seems to be just like I wrote some posts before: while one thread is reading data from file, another could process already read data - I am just considering malcolmmc's idea of blocking queue - one thread to perform I/O operations and one thread to process data - these threads would be connected through blocking queue....hmm that sounds good to me.. thanks malcolmmc
thank you guys for your help & suggestions and if you still have something to advise me, I will be thankfulSeparation of concerns, dude. Read the raw data in, in one thread, and split out the processing to multiple threads. I really advise you take the time to actually measure the performance of the multi-threaded processing vs the single-threaded one though. I mean, really do actually do that. Don't just assume - as so many people do - that throwing more threads at every problem will always speed it up, because it's so often not the case.

Stop photo streaming uploading when I use some WIFI Hot Spot?

Hi!
Is it possible to stop photo streaming uploading when I use some WIFI Hot Spot?
I use tethering from other 3G connection a lot, so i'm consuming a lot of Mb!

I missed you in iChat yesterday as I was posting this to let you know.
It is mostly as the Page 7 stuff is but laid out in a form that can be used without tables or extra div sections of HTML.
As I am sure there are newer things that we have missed such as
http://b-l-a-c-k-o-p.com/CamCamX.html
and other VJ type apps that might warrant some sort of mention.
Anyhow it might flush out some some more anyway.
I still feel that the credit for this lies with you.
I am going to leave it for a while to see what comes up here and in the other forums of items that might need a mention.

IPad AIR (7.04) won't stop Rebooting itself. Reset does not solve.

Problem started after/during installing app from appstore (either Gmail or Google Translator)
Resetting device is successfull, but auto reboot keeps taking place : Apple logo appears fir 10 sec or so. then the small logo clock that hardly is turning at all....
After some minutes: device reboots itself, over and over.
I cannot stop this behaviour. Reset (pressing home and upper button) DOES reset but issue remains....

Sadly it seems the iPad AIR and IOS is not fully booted enough for iCloud to find my device.
It shiws "offline" on www.icloud.com after logging on.
Now attempting iTunes 11.1.3 . Jyst installed it in Windows 7 64bit PC
PC detects apple device through USB
iTunes after the setup attemots to connect to it, but fails with a popup:
"ITunes could not connect ti iPad AIR 'iPad AIR Erwin' because it is blocked with a passcode. YOu must enter your passcode on the iPad befire it can be used with iTunes"
Well... nice indeed huh ?
It detects my device with correct name, senses it has passcode and is blocked....
But i cannir enter the code on the iPad since it is 'still' booting ( small white icon wheel that hardly is twirling)
Thus is a deadlock. Cannot factory reset because i cannot enter the code !?
