Socket Exception when closing the console

Hi ,
I'm running WLC & P Server 3.5/WL 6.1 in the following environment
Weblogic Version: WebLogic Server 6.1 SP1
JDK Vendor: Blackdown Java-Linux Team
JDK Version: 1.3.1
Operating System: Linux
and I'm getting very often this exception when closing the console

I also get the same behaviour under WL 6.1 alone when closing the console.
Does anybody know what this means?
Thanks,

Ooops, sorry for the repost.

Socket Exception when closing Server Socket Streams if Client closes first

Hi
I have 2 processes - a Server socket and a client socket. If I close the Client process first, and then try closing down the Streams on the Server process, I get a SocketException with message "Socket is closed" when I try and close the 2nd Stream. It does not matter on the order of the Stream being closed down, the exception is always thrown when I try and close the second stream. The code snippets are below:
SERVER =======
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;
public class ServerSocketTest {
public static void main(String args[]) {
try {
ServerSocket ss = new ServerSocket(9999);
Socket s = ss.accept();
// Get refs to streams...
InputStream is = s.getInputStream();
OutputStream os = s.getOutputStream();
// sleep to let client shutdown first...
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
System.err.println(e);
System.err.println("B4 inClose: isBound=" + s.isBound());
System.err.println("B4 inClose: isClosed=" + s.isClosed());
System.err.println("B4 inClose: isConnected=" + s.isConnected());
System.err.println("B4 inClose: isInputShutdown=" + s.isInputShutdown());
System.err.println("B4 inClose: isOutputShutdown=" + s.isOutputShutdown());
s.getInputStream().close();
System.err.println("After inClose: isBound=" + s.isBound());
System.err.println("After inClose: isClosed=" + s.isClosed());
System.err.println("After inClose: isConnected=" + s.isConnected());
System.err.println("After inClose: isInputShutdown=" + s.isInputShutdown());
System.err.println("After inClose: isOutputShutdown=" + s.isOutputShutdown());
s.getOutputStream().close(); // will break here with SocketException!
System.err.println("After outClose: isBound=" + s.isBound());
System.err.println("After outClose: isClosed=" + s.isClosed());
System.err.println("After outClose: isConnected=" + s.isConnected());
System.err.println("After outClose: isInputShutdown=" + s.isInputShutdown());
System.err.println("After outClose: isOutputShutdown=" + s.isOutputShutdown());
s.close();
} catch (Exception e) {
System.err.println(e);
CLIENT ======
import java.net.Socket;
public class ClientSocket {
public static void main(String args[]) {
try {
Socket s = new Socket("localhost", 9999);
try {
// sleep to leave connection up for a while...
Thread.sleep(2000);
} catch (InterruptedException e) {
System.err.println(e);
s.close();
} catch (Exception e) {
System.err.println(e);
The debug shows that isClosed() is set to 'true' after the first call to s.getInputStream().close(). The Sun API Socket class getOutputStream() has a call to isClosed() at the start of the method - it then throws the SocketException that I get. Why does the SocketImpl do this before I get a chance to call a.getOutputStream().close()?
One final thing, the calls to s.isInputShutdown() and s.isOuputShutdown always seem to return false even if the Streams have had their .close() method called.
Any ideas/help here greatly appreciated.
Thanks
Gaz

Ok, I know what's going on now - I needed something to do on Friday afternoon anyhow!
Basically if you call either getOutputStream.close() or getInputStream().close(), the underlying Sun implementation will close the Socket.
Here's what's happening under the covers in the Sun code:
s.getInputStream() is called on the Socket class.
The Socket class holds a reference to the SocketImpl class.
The SocketImpl class is abstract and forces sublclasses to extend it' s getInputStream() method.
The PlainSocketImpl extends SocketImpl.
PlainSocketImpl has a getInputStream() method that returns a SocketInputStream. When the stream is created for the first time, the PlainSocketImpl object is passed into the Constructor.
The SocketInputStream class has a close() method on it. The snippet of code below shows how the socket is closed:
<pre>
* Closes the stream.
private boolean closing = false;
public void close() throws IOException {
     // Prevent recursion. See BugId 4484411
     if (closing)
     return;
     closing = true;
     if (socket != null) {
     if (!socket.isClosed())
          socket.close();
     } else
     impl.close();
     closing = false;
</pre>
So, it seems that out PlainSocketImpl is getting closed for us, hence the SocketException being thrown in Socket.getOutputStream() when I call it after Socket.getInputStream()/
I've not had a look at the reason why the calls to s.isInputShutdown() and s.isOuputShutdown always seem to return false even if the Streams have had their .close() method called though - any thoughts appreciated.
Thanks

"No more data to read from socket" exception when testing connections

I will appriciate your help with the following problem.
We have the follwoing errors in the weblogic.log (We are using weblogic 8.1.0.2 and Oracle 9.2.0.3)

These exception occures every hour after the connection pool is being closed and refreshed.
Also there are a lot of the follwoing warnning in the log :
<BEA-001074><A JDBC pool connection leak was detected.
Does these two problems connected? What can we do in order to solve it?
Thanks

Something is killing your DBMS connections out from under the driver.
Do you have a firewall between WLS and the DBMS, or a flakey network?
Contact BEA support to get the 8.1sp2 patch for getting meaningful
connection leak traces (CR209251_81sp2.jar). When that patch is installed
the leak messages should show a full stack trace of the application code
where the connection was obtained. It is that application code that
somehow failed to close the pool connection, causing a pool leak. I
suspect that the application code got an unexpected exception, such as
when/if the DBMS/network/firewall killed a connection. In this case I
believe the application went through an exception-handling path that
forgot to close the connection.

Connection reset when closing the client program.

when closing the client program I get the error message Connection Reset
at ServerThread.run(SeverThread.java:244)
which is the following file
i've marked the 244: on this file on the left of the file.
after this I have the client program which is called Client.java
the error happens when I close the client program and the error is on the serverthread side of the application. Please anyone help out with this one.. Thanks.

"onclose event of application", at least do something such as call wait() on ReadersWhy? Who is going to notify() it?
and close the Sockets and then Readers/WritersI won't even ask why about that because it is 100% dead wrong. Close the outermost Writer or OutputStream. That flushes the output, closes the socket, and closes any input streams or readers. Taking your advice the flush() cannot occur. But the evidence is that he is closing the socket: in fact the operating system does that anyway. Possibly he needs to take the advice about closing the Writer/OutputStream, to cause the flush(), which might stop the server from writing. But that depends on the application. If it's legal in the application protocol for the client to exit while the server is still writing he will just have to put up with the 'connection resets', or at least interpret them properly rather than just logging them as an error.
If your using a window(GUI) you can use the main frame with a Window closing event.And that's completely irrelevant because the error happens on the server.

Javaw.exe hangs when activating the console

When activating the console in WebStart, it looks like WinXP doesn't release javaw.exe, even when the application gets closed. This never occurs when the console is not activated.
A possible bug ?
- Pierre-Yves

I have searched so many forums and every body (if any at all) state I need to edit my code to sort this out. Well here's a shocker! :) i dont write any code. I am installing J2RE1.4.1_02 and unfortunately due to our other applications, can only use this version. I am installing it on XP images and so far have only had a 60% success rate. Could there be an application installed or a process that is preventing the console from opening? I noticed the way the data is entered into the registry is slightly different from the successful ones. Is there a work around?
Please I am desperate as I am installing this onto 400 PC's.

I lose the connection when closing the CMD

Hi guys,
I have configured a standalone listener as following:
C:\Program Files (x86)\Java\jre6\bin> java -Dapex.home=D:\list -Dapex.images=C:\images -jar D:\apex.war
Afterward,
If I close the CMD, I will lose the connection, and I have to reconfigure it again.
If I open APEX locally , I mean by using the shortcut "Get Started With Oracle Database 11g Express Edition" , Then I will lose the connection that uses the default port of the listener, that is 8080.
After I configured the listener I got this message on the CMD
-- listing properties --

Hi,
I'm not sure I got your question right, but I'll try to find some solution anyway.
If I close the CMD, I will lose the connection, and I have to reconfigure it again.That's what happens when a shell is terminated - all associated processes will stop as well. However, if you have a apex-config.xml in your apex.home you shouldn't need to configure your APEX Listener each time your start it, but it would reuse an existing configuration.
If I open APEX locally , I mean by using the shortcut "Get Started With Oracle Database 11g Express Edition" , Then I will lose the connection that uses the default port of the listener, that is 8080.Now, if you have XE running on the same (local) machine as you have your APEX Listener running in standalone mode, you probably have a port conflict: By default, both APEX Listener in standalone mode and the Embedded PL/SQL Gateway (EPG) use port 8080. The EPG is activated as web server for APEX in XE after a fresh installation, the APEX Listener would be an alternative in that case. You can either stop the EPG, or reconfigure any of the two web servers to use a different port, if you want to run them parallel.
To change the port used by the APEX Listener in standalone mode, you simply add another parameter to the startup: -Dapex.port=8888 and you're done.
To change the port used by the EPG, connect as sys and run the following
EXEC DBMS_XDB.SETHTTPPORT(8888);
COMMIT;If you want to disable the EPG, simply set the port to *0* .
After I configured the listener I got this message on the CMDThat's what it should look like.
No, since your topic is "lose the connection when closing the CMD", I assume you search for an alternative. You could run the APEX Listener as a Windows service, even in standalone mode. To do this, you create a batch file, e.g.
%JAVA_HOME%\java -Dapex.home=D:\oracle\APEX_Listener\_home -Dapex.images=D:\oracle\apex_4_0_2\images -Dapex.port=8888 -jar D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\apex.war >>D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\my_apex_listener.log 2>&1Note that you have to set JAVA_HOME as system property or replace the call with the absolute path to your JDK or make sure the JDK is in your PATH variable.
Of course, you can and should change the other directories as well to fit to your system.
Next, create a Windows service, e.g. using [url https://iain.cx/src/nssm/]NSSM (free) or [url http://support.microsoft.com/kb/137890]SRVANY (MS, non-free), that starts your batch as a windows service.
The command for creating that service using NSSM could look as follows
nssm install APEX_Listener D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\startup.cmdYou can edit the service properties afterwards, e.g. change the start mode from "Automatic" to "On Demand".
I hope this answers your question. If not, please point me into the right direction.
Thanks,
Udo

"...handle is invalid" : Error only when closing the Application, at RunTime everything seems fine...

HI,
first of all: I'm relatively new to LabWindows, working on it during some practical work as a Student
(yeah, and sorry for the bad english, I'm from Germany)
To the Problem:
The first important Information:
After having searched for a solution, I just don't know, what to do,
My Project consists of ONE Main.uir-File with a Tab, a "Main.c" that basically handles the main .uir-Stuff and some Initiating-Stuff and in addition to that Several Sub-Sourc-Files, one for each Tab-Panel of the Main.uir-Tab.
To use the UI-Items on the Main-Tab with the Sub-Sources, I am initiating Tab-Handles at startup, that can be used by the SubSource-Files, like:
GetPanelHandleFromTabPage (PANEL, PANEL_TAB, 2, &BALU);
With this Handle, I can identify every UI-Items, when working with the SubSources
The second important information:
In some of the TabPages of the .uir there are several ControlArrays. To use them I create a ControlArrayHandle, like:
MWSAverageHandle = GetCtrlArrayFromResourceID (BALU, MWSAverageArray);
No, I am able to identify specific elements of the Arrays, like:
SetCtrlVal (BALU, GetCtrlArrayItem (MWSProgressHandle, ActiveBalun), ProgressString);
Now there is a Problem, I am not able to solve:
During runtime, everything works out fine, I can use every element of a ControlArray with this ControlArrayHandle ("MWSProgressHandle"), everything works perfect, no errors at all. BUT, when closing the programm, I get the following error-message:
NON-FATAL RUN-TIME ERROR: "Baluns.c", line 313, col 16, thread id 0x00000AB8:
Library function error (return value == -4 [0xfffffffc]). Panel, menu bar, or control array handle is invalid
But this seems somehow ridiulous to me, because at runtime every single line works perfect, every Array-Item can be used without Problems...
Is there anything I am just not able to see???
Thanks a lot for your help.
Greeting from Lübeck, Germany!
Mathias
Solved!
Go to Solution.

Maybe I just figured something out:
First of all, most of the Functions, that cause the Error, are in Timer-Callbacks (at this state of development, ALL of them)
So I just added a Test-Function in a normal Button-Callback, which contains a "GetCtrlArrayItem"-Function, and this specific Line does NOT cause an Error... (Or at least it does not occur in the Error-List, when clicking "continue" in debugging-mode). Somehow the Timer-Callbacks seem to be called, when closing the Application...
BUT: this happens when I don't do anything in the Application, and the all Timers are Disabled, until some Buttons are pushed (so when I close the application right after opening it, they still should be disabled)
@ Wolfgang:
After discarding I do not want to use one of the handles, or at least I'm not doing that purposely
@ Roberto:
Actually I am only discaring the MainPanel-Handle in the Main.uir (and one other Panel, but the error occurred before implementing that other panel). Do all Handles (PanelHandles as well as ControlArrayHandles, TabPageHandles and so on) need to be discarded?
And no, I did not check the Variable Window, I was not aware of this possibility, I will try to figure that out.

Macbook pro not turning on after SMC reset. I have the following problem. Yesterday I noticed that my mbp 2011does not sleep when closing the screen. smc due loud fan and an X on battery symbol

Yesterday I noticed that my mbp 2011 dos not sleep when closing the screen cover. Today I Turner my laptop in. However the fan was working loudly and stayed loud. After Start I noticed an X on Battery symbol. Clicking on it, it showed 'no battery.' I found out that a potential solution for this problem was SMC reset. I also noticed that the leds on magsafe was not lightning. Despite this I tried to execute the smc reset as described on apple support site. Switching off, plugin the magsafe connector, pushed the buttons shift + alt+ ctrl + power. Then i pushed the power button, but my mbp is not turning on. I pushed several times on the power button but nothing works. The magsafe is also dark meaning the leds not lightning. Can anyone here help me on this ?

Problem solved by my own. But do not how :) magsafe again working and the laptop tooo

Exception when retrieving the WS invoker using the execution destination

We got exception when we had tried to call WS in Web Dynpro for Java (NWDS 7.1 SP 5):
"Exception when retrieving the WS invoker using the execution destination".
We imported model as Adaptive Web Service Model with destination and
implemented Component Controller using document
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/900bbf94-a7a8-2910-e298-a651b4706c1e
We used:
1. Netweaver 7.1 CE
2. Backend R/3 system with RFC wrapped by Web Service without autorization on R/3
3. In our CE system we created two logical destinations (metadata and execution) to R/3 Web Service

Hi Yuriy,
It would be great if you can say how exactly you solved the problem as i am encountering the same error.

Netweaver throwing following exception when calling the ProductionOrder WS

Hi,
when calling the ProductionOrder web service I get the following exception from the system:
nested exception is: com.sap.engine.services.ts.exceptions.BaseSystemException: Exception ( SAP J2EE Engine JTA Transaction : [0ffffffaa60fffffffe00103e] ) in rollback.
The system was migrated from Netweaver CE 7.1 SP4 to SP5 before the error started to occur.
Any ideas how to fix this? Start/Stopping ME didn't do the trick.
Kind Regards,
Christoph Mertins

Exception when closing an Applet window

Hi,
Every one.....
I have added Swing components to the JApplet. Everything is fine with the program . But when i am closing the appletviewer window it is throwing the following exception :
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException: component argument pData

So how to resolve this one, can anyone ?
Bye

I could be proven wrong, but I think you can use hide() and show() for your windows. You could make a windowListener that when a user tries to close the window you would have it hide that window instead, and show the underlying window:
http://java.sun.com/docs/books/tutorial/uiswing/events/windowlistener.html
You might also want to make the new window that pops up a modal dialog window.

Hope that helps.

Hit the exception when editing the value of row key column in a new created row in a table

1. I created a view object with 2 entity objects (parent table: YARD_FIXED_SLOT - child table: YARD_FIXED_SLOT_DETAIL) and the primary key of child table composes of 2 columns ( one of them is FK: YardFixedSlotDetail.FIXED_SLOT_ID REFERENCES YARD_FIXED_SLOT(FIXED_SLOT_ID)
SQL queries:
SELECT YardFixedSlotDetail.FIXED_SLOT_ID,
       YardFixedSlotDetail.MODIFIED_DT,
       YardFixedSlotDetail.SLOT_FROM_N,
       YardFixedSlotDetail.SLOT_TO_N,
       YardFixedSlotDetail.USER_ID,
       YardFixedSlot.BLOCK_M,
       YardFixedSlot.BLOCK_N,
       YardFixedSlot.FIXED_SLOT_ID AS FIXED_SLOT_ID1,
       YardFixedSlot.SECTION_N,
       YardFixedSlot.STATUS_C,
       YardFixedSlot.TERMINAL_C
FROM YARD_FIXED_SLOT_DETAIL YardFixedSlotDetail, YARD_FIXED_SLOT YardFixedSlot
YardFixedSlotDetail.FIXED_SLOT_ID = YardFixedSlot.FIXED_SLOT_ID
2. I dragged this view object into JSF page as an ediable table and add 'add' button to add a new row to the table. and the handling logic in managed bean is as followed. now one new row can be added succesfully in the table.
    public void processSlotDetailCreation(ActionEvent ae)
        DCBindingContainer bindings = (DCBindingContainer)getBindings();
        DCIteratorBinding dciter = bindings.findIteratorBinding("YardFixedSlotDetailFindAllByBlock1Iterator");
        Row row = dciter.getCurrentRow();
        //get the last row for the index and create a new row for the //user to edit
        Row lastRow = dciter.getNavigatableRowIterator().last();
        YardFixedSlotDetailFindAllByBlockRowImpl newRow = (YardFixedSlotDetailFindAllByBlockRowImpl)dciter.getNavigatableRowIterator().createRow();
        newRow.setFixedSlotId(new Integer(21));
        newRow.setUserId("adftest");
        newRow.setModifiedDt(new Timestamp(System.currentTimeMillis()));
        //bug exist here
        newRow.setSlotFromN(new Integer(1));
        //newRow.setSlotToN(new Integer(1));
        newRow.setNewRowState(Row.STATUS_INITIALIZED);
        int lastRowIndex = dciter.getNavigatableRowIterator().getRangeIndexOf(lastRow);
        dciter.getNavigatableRowIterator().insertRowAtRangeIndex( lastRowIndex+1, newRow);
        // make the new row the current row of the table
        dciter.setCurrentRowIndexInRange(lastRowIndex);
        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
        //table should have its displayRow attribute set to //"selected"
       // AdfFacesContext.getCurrentInstance().addPartialTarget(slotDetailsTable);
3. When filling in a new value for SlotFromN column (note that SlotFromN column and FixedSlotId column are the rowKey), hit the exception below:

4. I think problem maybe is related with row key, but I need end user to change rowkey column value. does it allow changing the value of column as row key? I found this problem maybe only occur for new created row. For those existing rows, even I change the value of row key column, no such problem occurred, how do I handle this situation?
Appriciate if anybody can help.

Hi Bangaram,
Thank you for your reply.
The error: "Root cause error code is JBO-34014. Error message parameters are {0=oracle.jbo.Key[21 null ], 1=root} "
I didn't create master records, I just used joint queries for information display of both master and detail. I am trying to create a row in the UI table to create a new detail record and master record already exists.
The row key for new added row in UI rich table is [21 null ], row key of detail records table composes of 2 columns. 21 is for FixedSlotId and null is for SlotFromN. when I provide a new value for SlotFromN column in UI rich table, problem will occur.

A surprising exception when call the EJB

The CMP-bean---UserEJB has been deployed successfully.
Main client program:

But a new data-row has been inserted into the table successfully.
What on earth caused that? And how to solve this problem?
Any reply is welcome.Thanks!

I have only a partial solution (if you find it all I'll be happy to know myself...)
I had the same problem. It occurs that the problem is related to the definitions of transactions attributes in the table of the transaction tab. go to this tab and change the attribute from "required" to "supported" (I assume you have "required" and it should not be) in the method which causes the exception.
hope this helped.

Exception when run the link for exchangeProfile.

Hi all:
       It is found that exchangeProfile service is not installed or not deployed on NW at least, when I check through visual admin. exchangeProfile, IntegrationServices, ExchangeDirectory, ExchangeRepository are not deployed services,
      When run http://exxpi:500000/exchangeProfile, the page shows and I can maintain Connectoin parameter, and can import exchangeProfile file, but after that, when try show exchangeProfile by refresh the screen, nothing shows. (I don't know if it is a problem)
      but when run the link.
