SocketException error.

From time to time one of our JSP pages is throwing this error

 It doesn't do it all the time and it doesn't seem to cause a probelm or have
 any effect on the output on our clients. Can someone tell me what this
 error is and what I can do about it?

Typically, this means that the browser connection has gone away. This could
 happen if the user browses to another page or closes the browser before the
 server is done sending the current page.
 It's harmless.

Getting SocketException: Error in poll for fd: 'nn', revents 'nn+n'

 I'm running WL 5.1 SP9 on a HP9000 HPUX 11.0 with JRE 1.2.2-06 and I get the following:
 java.net.SocketException: Error in poll for fd: '21', revents: '25'

 Any help appreciated.
 Please cc my email if possible
 Thanks

Derrick,
I believe that this is a spurious error caused by a HTTP client which
doesn't close the socket cleanly. This exception should be squelched in
newer versions of the product. Until you can upgrade I believe you can
safely ignore this message.

Error while running the console on WLCS 3.5

Hi there,
I'm running WLCS3.5/WL 6.1 and I'm getting very often this exception when
using the console:

I also get the same behaviour under WL 6.1 alone when accessing the console.
My environment is:
Weblogic Version: WebLogic Server 6.1 SP1
JDK Vendor: Blackdown Java-Linux Team
JDK Version: 1.3.1
Operating System: Linux
Does anybody know where this is coming from?
Thanks,
Dan

Daniel,
Thanks for the hint.
Indeed, these are all file descriptors and the error has to do something
with the way poll(2) is implemented in the gcc library
and/or used by WebLogic. revents is a bitmask constructed by OR-ing a
combination of some event flags.
It is weird though that this appears only when running the console and never
when running any other application.
I'll keep digging, maybe I'll find why this happens. I will also try to
install it on different Linux distros.
Thanks again,
Dan

Dan,
I'm no LINUX guru but I would guess that "fd" is file descriptor (for the
socket connection), and WebLogic cannot acquire one for a socket it is
trying to open. I would root around for config information surrounding the
number of sockets you can open simultaneously.
Sincerely,
Daniel Selman

Hi,
For WLS version 9.2 there is a Fix Available for the same issue : CR309671 Please contact Oracle support to get the Patch (CR309671).
After BEA/Oracle integration the Patch Naming convention is changed so to get the TAR version of the Patch Number u need to contact Oracle Support.

HTTP Error BEA-101083

Hi all.
I am testing in a BEA WebLogic Server 8.1 SP1 an application that uses Struts.
When I open a form, sometimes but not always, I get the following error:
<Jul 6, 2004 3:59:47 PM CEST> <Error> <HTTP> <BEA-101083> <Connection failure.

This error does not produce any malfunction in the application. On the browser
side, anything strange is detected, but I'd like to know the reason of this in
order to avoid the exception to raise. I have no idea about whether this is related
to the BEA Weblogic configuration, to something in my application, ...
Has someone experienced something similar or knows some possible reason?
Thanks.

SocketException BEA-101083 Weblogic 9.2

Hi,
we are facing a problem in our production environment, we get pratically every minutes the following exception :
<30 juin 2008 10 h 27 CEST> <Error> <HTTP> <BEA-101083> <Connection failure.

 at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:117)

What can be the cause of this ? Our users are telling us that the application goes very slow and this is the only abnormal log that we found.
Thank you,
Quentin Anciaux
<[email protected]>

Hi, the problem happens pratically once or two per minute while the application is in use... when the application is not used, no error happens.
So it happens very often... I thought it could be a problem with a proxy/firewall in the middle, but according to the guys in charge of this, nothing has changed on his side.
I've read things about a possible bug in the nativeIO implementation, would it be safe to deactivate nativeIO to see if this bug arise with pure java socket ?
Also this problem only occurs in our production environment, we have 4 others environment used for testing/training/integration and this error does not occur there.
Thanks for any help,
Quentin Anciaux

Error connecting to MySQL database

Well I am a beginner trying to get the basics of JDBC. I am following a simple connection tutorial and I cannot even make this work. I receive an error when I run the program. It is a nested error that begins with "java.io.EOFException". I'm thinking it has something to do with the URL I am using to connect to the database. Any ideas?
Here is the code I am using if that helps at all.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class jdbctry {
public static void main(String args[]) {
    Connection con = null;
    try {
      Class.forName("com.mysql.jdbc.Driver").newInstance();
      con = DriverManager.getConnection("jdbc:mysql://url:port/database",
      if(!con.isClosed())
        System.out.println("Successfully connected to " +
          "MySQL server using TCP/IP...");
    } catch(Exception e) {
      System.err.println("Exception: " + e.getMessage());
    } finally {
      try {
        if(con != null)
          con.close();
      } catch(SQLException e) {}
} edit- I think the problem was I had a bad port number assigned to the URL. This time I got a "java.net.SocketException" error. It says my connection timed out.
Message was edited by:

I'll assume that you've substituted appropriate values into that connection URL, right?
It s
// host = IP address or name of machine where MySQL is listening
// port = 3306 (default)
// database = instance you wish to connect to
// username, password have to be GRANTed access rights.
String url = "jdbc:mysql://host:port/database";Can you connect using the MySQL client and see the database you want in Java? If the client can't connect, neither can JDBC.

Just noticed error in samples for "Spry Rating"

Hello, everyone.
Just a heads-up if you are using the Spry Rating Widget.
According to the samples page at http://labs.adobe.com/technologies/spry/samples/rating/RatingSample.html if you want to disable multiple votes (at least until page refresh) you set the option "allowMultipleVoting:false".
It should be "allowMultipleRating:false".
Took me almost an hour to figure this one out. Hope this saves a few people some trouble.
^_^

disregard. sorry.

Multicast issue with Win XP

 I am wondering if anyone else has encountered Multicast problems with Windows XP.
 I think I am, and believe these issues are preventing the servers in my clusters
 from syncing their JNDI tree bindings.
 I noticed this while configuring a JMS Server and Queues in a clustered development
 environment. It is a simple cluster of 2 servers both on a single Win XP machine,
 see post 14712 in weblogic.developer.interest.jms (http://newsgroups2.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.jms&item=14712&utag=).
 I tried the MultiCast test utility (http://e-docs.bea.com/wls/docs81/admin_ref/utils.html#1199798)
 and found what I think means I have a multicast problem. Output follows:
 ------ Begin MultiCast test utility output: ------

 -A 237.155.155.1 -t 15

 I expected to see "Received message X from server200" messages, like I saw from
 the Win2K machines I tried.
 There is a Microsoft Knowledge Base Article - 827536, "An IP multicast may not
 be sent correctly from Windows XP or from Windows Server 2003" (http://support.microsoft.com/default.aspx?scid=kb;en-us;827536).
 The issue appears to be limited to computers with more than one network adapter
 (like I have). I am pursuing the hotfix from Microsoft, but these things take
 time.
 Anyone else having similar issues?
 Any and all help is appreciated.


 I am facing a problem and believe that its because of multicast too. The problem
 is seen on XP but not on W2000.
 The MulticastTest when executed does not show any message exchange at all. When
 a server is started I get following exception

PosixSocketMuxer exception

Hi all,
 Would like to find out if anyone faced the following problem before.
 I've got a Servlet on WLS 6.1 sp2 invoking an EJB running on a different
 instance of WLS 6.1sp2. Both the instances of WLS 6.1 are physically
 separated and are running on HP-UX 11.
 When the browser submits a request to the Servlet, the servlet invokes
 the EJB, EJB does some database processing and returns. Servlet receives
 the results from EJB and forwards the request to a JSP that is processed
 to display the page to browser... All this works fine.
 However, after the resulting page has been returned the following was
 logged in the WLS 6.1 instance the servlet is on.

 Was wondering anyone faced a similar problem before and if so, how was
 it solved?
 Thanks!
 Rgds,
 Steven.


The exception is genuine and harmless. The socket opened from the html
 client (browser) was time-out or closed.
 This is fixed now. But could not make it to 61 SP3.
 Open a case with support, if you need a one-off patch.
 Cheers,
