IOException - WEB8001 - when writing to servlet response outputstream

I am attempting to port a Java servlet application from iws 6.0 to 6.1, sp2, but am encountering IOExceptions during load testing.
The servlet composes its response in a character array, and then calls the following method to write the characters to the servlet response object:
static void writeResponse( HttpServletResponse response, char[] chars, String charset ) throws IOException {
    OutputStreamWriter writer =
        new OutputStreamWriter( response.getOutputStream(), charset );
    char[] buffer = new char[8192];
    CharArrayReader reader = new CharArrayReader( chars );
    int read = 0;
    while(( read = reader.read( buffer, 0, 8192 )) > -1 )
       writer.write( buffer, 0, read );
    writer.close();
}Under moderate load (2-4 simultaneous connections), an IOException will sometimes be thrown. The stack dump is:

of data when the exception is thrown.
Any clues about how I might debug this?

What are you using as your test client?The test client is WebStone 1.0. WebStone always downloads the whole response, and reports the size of the response in bytes. From this I can see that when the IO exception occurs, webstone is unable to read the whole response, as it reports a smaller size.
So, I do not think the problem is that the client has prematurely aborted its download. WebStone doesn't work that way. I think something has gone awry on the server side, and this worries me.

Streaming Large Files to Response OutputStream consumes plenty of memory

When we write large file's (> 100 MB) binary content to the Servlet Response OutputStream using the write method, it consumes plenty of Heap Memory on the server (Weblogic 7). The Heap does'nt come down after
writing to the outputstream, it stays high for quite a long time, infact it comes down only we access the same page again. Is there a way to get this optimized?
TIA.

The servlet container will buffer your output, so that it knows how much of it there is, so that it can set the Content-Length header, so that the recipient knows where the payload ends.
I don't know about Weblogic, but in Tomcat there are AFAIK two ways to get genuine streaming instead of buffering: set the Content-Length header before writing any output (and if you know the content length in advance). Or use chunked encoding (set the "Transfer-Encoding: chunked" header, google for it.)
I don't know if it works, but if those two don't do it for you, you could also try forcing the reply to be HTTP/1.0 instead of HTTP/1.1, or disable keep-alive ("Connection: close"). HTTP/1.0 (which doesn't have keep-alive) and no-keep-alive might not need the Content-Length header because closing the socket will give an EOF to the recipient, so it knows where the payload ends.

Java.io.IOException: WEB8001: Write failed

I have written a servlet to download a tar file.
The Servlet takes the parameters and create a tar file based on the parameters and then opens the file for download for the user. I am able to download the tar file and the contents of the tar file is ok. But when I write the content to the OutputStream I getting an IOException
(1) Refer to the code snippt below. Here I am getting the following IOException: Cannot read and write data java.io.IOException: WEB8001: Write failed
private void sendDownloadFile(File downloadFile, HttpServletResponse response) {
try {
response.setContentType(contentType + "; name=\""

Long length = new Long(downloadFile.length());
response.setContentLength(length.intValue());
response.setHeader("Content-Disposition", "attachment; filename=\""
+ downloadFile.getName() + "\"");
OutputStream outStream =
new BufferedOutputStream(response.getOutputStream());
InputStream streamIn = new BufferedInputStream(
new FileInputStream(downloadFile));
byte[] tarBytes = new byte[1024];
while (streamIn.read(tarBytes) != -1) {
outStream.write(tarBytes);
outStream.flush();
streamIn.close();
}catch (FileNotFoundException fnfex) {
logger.fatal("File is MISSING!!");
}catch (IOException ioex) {
logger.fatal("IOException: Cannot read and write data " + ioex);
catch (Exception e) {
logger.fatal("Download Exception: " + e);
}Any help would be appreciated.

Error in getting the servlet response

Below is my ErrorPage Servlet. Whenever a 404 page not found error is encountered, the error page servlet reads the 404.html, and writes the content to the response. But I am not able to see the content in IE, but works fine in mozilla.
public class ErrorPageServlet extends HttpServlet {

Hi..
Thanks for the comment.
Below is how my web.xml entry looks like.
The requirement is to send a 404 error response and that will be handled by a servlet which inturn writes the output to the response object.
     <servlet>
          <servlet-name>ErrorPageServlet</servlet-name>
          <servlet-class>com.test.ErrorPageServlet</servlet-class>
     </servlet>
     <servlet-mapping>
          <servlet-name>ErrorPageServlet</servlet-name>
          <url-pattern>/error</url-pattern>
     </servlet-mapping>
     <error-page>
          <error-code>404</error-code>
          <location>/error</location>
     </error-page>>>
the first option to turn off the "show friendly html error pages" works fine.
It would be better if I can get a different solution

Concurrent processing of POST requests and automatic flushing of the servlet response buffer in WLS6.1.

          Hi all,
          I encountered the following 2 servlet problems in WLS 6.0/ 6.1:
          1. Processing concurrent POST requests
          WLS seems to disallow concurrent executions of any servlet's doPost servlet method.
          When two clients attempt to send a request to a servlet using POST, the socond
          one
          is blocked until the first customer is served. In essence, the servlet ends up
          operating in
          1-user mode. I just learned from Jervis Liu that the problem is solved in WLS6.0
          if you disable http-keepalive.
          For WLS 6.1 a partial workaround is to make the servlet work in a single-thread
          mode (by implementing the javax.servlet.SingleThreadModel interface). In this
          case,
          WLS dispatches concurrent requests to different instances of the servlet.
          This doesn't completely eliminate the problem - still only one customer can be
          connected at a time. The improvement is that once the first customer is disconnects,
          the second can be served even if the doPost method for the first has not finished
          yet.
          2. Flushing the response buffer in WLS 6.1
          The servlet response buffer is not flushed automatically until doPost ends, unless
          you
          explicitly call response.flushBuffer(). Closing the output stream doesn't flush
          the
          buffer as per the documentation.
          I see that other people are experiencing the same problems.
          Has anyone found any solutions/workarounds or at least an explanation.
          Any input would be highly appreciated.
          Thanks in advance.

Thanks for replying. Here my answers:
          > Did you mark your doPost as synchronized?
          No.
          > Also, try testing w/ native i/o vs not ... is there a difference?
          With native I/O turned off I get a little lower performance, but the
          difference is not too big.
          Best,

Do we need to restart the Tomcat server each time when we modify servlets?

Hi Friends,
Do we need to restart the Tomcat server each time when we modify servlets. Or is there any otherway to achieve the functionalitly?
Thanks and Regards,

Hi kajbj,
Java guys are mostly using TOMCAT,so for me it seems to be the best place.That's not correct. Most people who are writing stuff for the web might be using Tomcat, but there are lots and lots of Java applications that aren't for the web.
Is there any other reason behind your question.Yes, this forum is named "New to Java" and Tomcat questions shouldn't be asked here, even if people knows the answer to you question. You will probably get better and more detailed answers in a Tomcat forum. All othe guys there are actually using Tomcat, and they know the small differences between the different versions, and how they behave on different operating systems. They do also know if you need to make configurations changes, and where you should make them.
So in future, please ask questions in a forum that is specific to the product that you are using.

Weblogic.utils.NestedRuntimeException when using javax.servlet.Filter

IDE: JDev 10gR3.4 & JDev 11gR2.3
ViewController technology: JSF/ADF Faces
Example code flow:
Run page2.jsf
MyFilter intercepts request, checks for parameter on session.
If parameter not null, goto page2.jsf
Else redirect to page1.jsf
page1.jsf has a button that sets the value on the session scope after clicking.
In jdev 11gR2.3, I get an weblogic.utils.NestedRuntimeException after clicking the button on page1.jsf. This error does not occur in jdev 10gR3.5. Although the application continues to execute and proper info is displayed, I’m wondering why this occurs and also if I should be concerned. Has anyone experienced a similar issue when using javax.servlet.Filter in 11g?
MyFilter code snipet:
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) {
        try {
            HttpServletRequest httpRequest = (HttpServletRequest)servletRequest;
            HttpServletResponse httpResponse = (HttpServletResponse)servletResponse;
            String redirect = httpRequest.getContextPath() + "/faces/page1.jsf"; //only difference here is 11g uses jsf, 10g uses jsp.
            String uri = httpRequest.getRequestURI().toString();
            Boolean mySessionAttribute = (Boolean)httpRequest.getSession().getAttribute("MYSESSIONATTRIBUTE");

I dont believe that solution pertains to my case. clicked() is invoked from standard jsf page and the adf controller is not acquired yet. i put a couple of print statements in the filter and it seems that the doFilter is called twice! This is not the case when running in 10g.
            if (uri.endsWith(redirect) || mySessionAttribute != null) {
                System.out.println("URI dofilter: "+uri);
                filterChain.doFilter(servletRequest, servletResponse);
            } else {
                System.out.println("URI sendRedirect: "+uri);
                httpResponse.sendRedirect(redirect);
            }11g weblogic console log:
URI sendRedirect: /11gFilterExample-ViewController-context-root/faces/page2
URI dofilter: /11gFilterExample-ViewController-context-root/faces/page1.jsf
URI dofilter: /11gFilterExample-ViewController-context-root/faces/page1.jsf

I believe whatever thats causing this occur could be why the exception is thrown...

[Solved] systemd - To fork or not to fork when writing services

Hello,
Many of the programs i write services for have the option to fork or not to fork. Or are
advertised as daemons but have the ability to not fork into the background.
I don't understand which i should choose when writing a new service unit.
When do you want a program to run in 'daemon-mode' and when don't you?
Do i lose/gain anything when i make such a choice?
Thank you.

[If you have a choice then use Type=simple for your systemd services. It is simpler and systemd will take care or proper process deamonizing, restarts and shutdowns.
Type=forking is for historical services that cannot be run in foreground. In this case process itself will take care of its deamonizing, but systemd should know the child pid somehow so you need to provide PIDFile= option as well.
Historical or not, Type=forking is necessary if you need to be able to order other services on the Type=forking service. Type determines the readiness protocol used by systemd. In the case of Type=simple, there is no protocol. systemd assumes that as soon as the binary is exec'd, the service is available. For Type=forking, services are considered ready after the MainPID exits (after the double fork), allowing for time to setup sockets or other resources needed to handle client requests (e.g. a database server or a web server). If you use the Type, you may find that dependent services fail to startup properly, as their dependencies aren't actually ready when systemd declares them to be.
Thank you, that really cleared it up for me
After your response, and re-reading the manual, it all makes sense now!

Error: NFS3ERR_NOENT -   This is by design of OneFS, we coalesce files and then flush them out to disk which is why the commit time is accurate but the file is not immediately available. however when an async option is used within the mount options this should be avoided if writing asynchronously to the cluster. Has anyone else seen this behavior lately? (current workaround is to store locally and transfer to the cluster via Finder)

That error can happen for many reasons...one of the reasons that I occassionaly get it is because I try exporting a movie to an external drive that has been formated in the old FAT32 instead of the NTSF standard. FAT32 only allows for file sizes up to 2 gigs. And as soon as it reaches that...I would get that error. I don't know if that is why you are getting that error...but it would be easy to check. 1) are you generating a file that is over 2 gigs? 2) is your drive that you are exporting to FAT 32 (just right click the drive in My Computer and select "properties" then just look for what it says next to "file system".

I entered new fields in a form that was created last year to update it. However, now when I view the responses, they are listed as Column 1, Column 5, etc. It doesn't show a label for the actual field when I view the responses. Can you please help?

Hi Mike,
CRSE is an OEM Product and for use with a custom application they have written. Unfortunately we don't their reports or how they are connecting, it would appear they were originally built off a SQL and then set to a Dataset in the app or they could be adding the data source at runtime. Lots of variations and without access to the source code to see what they are doing not much we can help you with.
You need to contact the OEM Partner for help in resolving this and find out what you can and need to do to update your SP and work with their canned reports,
Thank you

Open Hub DTP issue (Error 21 when writing to the local workstation)

Hi,
I am using an openhub destination to output my csv file. Its a local workstation share folder. Data Provider got around 50000 rows (expecting a 40MB file). When ever I execute the DTP, it run for first data package and fell down with below error message.
Error 21 when writing to the local workstation
Error while updating to target XXXXXXX (type Open Hub Destination)

Sometimes the file get created with partial entries, most of the times the file wont even get created. I created new dtps and tried the same. Changed the package size, servers, parallel processes etc, but of no use.
Thanks Neo

Hi Neo,
Did you try to define the logical/physcal file path from tcode FILE? If not can you try to use this option and see if it works.
Also can you change your DTP settings by reducing the data packet size to see if your facing this error message?
Thanks

Application Crashes when writing to TDMS

My application written with LabVIEW 2009 (9.0.1) crashes occasionally when writing to a tdms file. The application logs data to a tdms file at low sample rates (~1/min). Attached is the error information.
Could my error be related to this thread.

Brandon,
I attached better pictures.
This crash seems to occur randomly. However, It usually occurs after a day or two. I can't send the exact code, but can send the a simplified version of the code.
Thanks,

Problem with Arabic font: In certain contexts, when writing Arabic with vowel signs (fatha, damma, kasra, sukun) a sequence of sukun fatha/damma etc. would reverse automatically. Is this a known bug?

Problem with Arabic font: In certain contexts, when writing Arabic with vowel signs (fatha, damma, kasra, sukun) a sequence of sukun + fatha/damma etc. would reverse automatically. Is this a known bug?
Example: عَيْنٌ
would automatically convert to عَيُنْ
Funnily, it doesn't seem to happen here, but it does when entering text in a web interface (using Firefox, font Bayan) and when using Text Edit.
Seems to be a problem of a specific font, as e.g. Arial MS Unicode works fine. Any hints?
Thank you!

You can't do Arabic on MS Word for Mac. This app has never supported RTL scripts, so you need to use something else. Mellel is best, but Pages 5, TextEdit, Nisus Writer, Open/LibreOffice should work OK.
You switch between languages by using the "flag" menu at the top right of the screen or by using the keyboard shortcuts apple/command plus space. Go to system prefs/keyboard/shortcuts to make sure that is activated.
To see which key does what, you use Keyboard Viewer.

You place vowels on letters by typing the key for the vowel after the key for the letter. The vowels are on the option/alt keys, option/alt + a gives you َ
