No exception is thrown when my server socket dies

I have a server application running on sunOS 5.7.
To this I have both Windows and SunOS clients connected via TCP/IP. (Server built with jdk 1.2.2 and client with 1.3.0)
If the Server socket dies an exception is thrown in the windows clients but not in the sunOS client.
I need the exception to be thrown in the sunOS as well.
Is there anybody who knows how to get this done?
Thanks in advance.
/Henrik

You could poll the connection to see if its there.
If you want the client to register the event then have your client create a sort of listener of your own when it connects. By 'sort of listener' I mean extend the thread class and have it check the connection is not null every n seconds. If it is null then raise the exception yourself.
Would this do it?

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

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

Can anybody help me solving this problem?!

Younis2,
That was the important piece of information you needed to provide ;) I get the same exception if I try to do nested roles, but it doesn't prevent my application from starting - looks like it may be a bug - suggest you post a new thread with the word BUG in the title and give a really simple test case. I was able to reproduce quite simply by using tools->embedded oc4j preferences, and then editing the jazn configuration there to nest one role inside of another.

Will Exception be thrown when Socket is disconnected?

Hi
I would like to know will Exception be guaranteedly thrown if the other side(client or server) disconnect.
If not, how do I test the other side socket has been gone?
Thanks a lot
Matt

When the remote end of a TCP/IP connection calls close() on its socket, the remote operating system sends a FIN packet to your operating system. After this, if you try to read or write to the socket, you get an end-of-file indication. The indication depends on the API you use; it can be an IOException, -1, null, etc; read the API doc for the method you use for reading and writing.
A somewhat related question is: what if the peer computer crashes, or its Ethernet connector is unplugged. Then it can't send you a FIN or anything else. When you write to the peer, your operating system will send the data, and wait for a reply (ACK packet) for a while. The ACK doesn't arrive, so your OS will re-send, wait, re-send, and finally give up, after a minute or so. After that you'll get IOExceptions when you read or write to the socket.
If the remote end crashes or is unplugged, and you read() from a socket, nothing happens. Your read() will patiently wait forever for data that will never arrive. For this reason, it is sometimes advisable to have a "heartbeat" in your protocol: send some dummy "are you there" message occasionally. That will trigger the send/wait-for-ACK/re-send/wait-for-ACK process, and after a minute your read()s and write()s will IOExcept to tell you the other end is gone.

SocketException thrown when reading from socket.

I got a thread that listen on a socket for data with: while (LISTENING)
new AAAcknowledgeThread(serverSocket.accept()).start();
When the thread mentioned executes and tries to read from the socket with:
BufferedReader in = new BufferedReader(
new InputStreamReader(socket.getInputStream()));
A SocketException is thrown with the following stacktrace:

Does anybody know what could cause my problem?

If you are creating the Socket in another Thread then I don't think the thread you create can read from that InputStream/OutputStream. I remember doing something like this while transfering files through RMI. I was openning a File and passing the FileOutputStream to another thread that pulled the file through RMI. That thread couldn't write to the outputstream, and would throw an exception. When I let the thread open it up. It worked.

Optimistic Concurrency exception ALWAYS thrown when field set to "Fixed"

Hello,
I'm concerned that there is a bug in the ODP.net interaction with the Entity Framework for Optimistic Concurrency Checking.
I have a sequence field called tracker_id on a table that has a before insert trigger on it, which is updated to the next logical sequence number every time the record is updated. The tracker_id attribute in the object entity has had its "Concurrency Mode" set to "Fixed".
The problem is that irrespective of whether a record has been updated in another session or not, the optimistic concurrency exception is always thrown. Please see message below:-
"Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries."
code below
catch (OptimisticConcurrencyException ocex)
                string message;
                if (ocex.InnerException != null)
                    message = ocex.Message + "-" + ocex.InnerException.Message;
                else
                    message = ocex.Message;
                mm.ERRORCODE = "1";
                mm.ERRORMESSAGE = "Record has been updated by another user - Full Message: " + message;
                var poobject = ocex.StateEntries[0].Entity;
                tasdb.Refresh(System.Data.Objects.RefreshMode.StoreWins, poobject);
                tasdb.SaveChanges();
            }I have tried disabling the trigger on the table, but it still does the above.
Many thanks in advance,
Graeme

The data for the newly created row doesn't get inserted into the database until the commit is executed, so the insert trigger isn't called.
If you need to get the value without committing, then you should implement the trigger programmatically and drop the trigger from the database. The code below shows how you could do this.
ViewObject insertVO = findViewObject("myView");
Row newRow = insertVO.createRow();
SequenceImpl seq = new SequenceImpl("MY_SEQ", insertVO.getDBTransaction());
Long next = (Long)seq.getData();
newRow.setAttribute("primaryAttribute", new Number(next));
...You will need to replace MY_SEQ and primaryAttribute with the correct values for your example, but this should acheive what you want.

you should specify that this is an HTML veiwer explicitly, by writting something similar to this,
editor.setContentType("text/html");
kit = (HTMLEditorKit) editor.getEditorKit();
editor.setEditorKit(kit);
doc = (HTMLDocument) kit.createDefaultDocument();
editor.setDocument(doc);

Can't open HTTP server socket on port 50000 in dispatcher

We get the following message in the console_log for the dispatcher.

Hello Keith,
this errors occurs when the port http 50000 is already taken. Please could you check if this port on your machine is free or an other dispacther instance is already started on same machine. You can change the port in sap j2ee config tool (dispatcher-> services->http)

JUnit - How to assert exception is thrown?

If I use JUnit how do I assert an exception is thrown when I pass invalid parameters to a method I am testing? For example if I pass a username to a method that I know will cause the method to throw an InvalidUsernameException how do I assert this?

public void testBadParameter() {
try {
    objectUnderTest.myMethod(badParameter);
    fail("Foo!");
} catch (ExcpectedException e) {
    //ok
}

Which exception is thrown?

Which exception is thrown when a native method breaks?
For example: when a native method cannot access some device.
Is it RunTimeException, or just plain Exception, or perhaps something else?
Thanks.

The native - C - code is yours. If it encounters an
error, it is up to you to decide how to deal with it.No. Im using someone elses native methods.
Chances are, if you are trying to write a wrapper
around someone elses code...Exactly! :)
... you will find the code
throws C++ exceptions. You have to catch them and
deal with them.I know that. That is why I posted a question here. Question is: What is that exception?
One likely way to "deal with them" is to define for
yourself the exceptions you would like to see in
java, and have the native methods construct and throw
those java exceptions. The JNI interface includes
ways of throwing exceptions while in native code.I don't know that. If you could provide some example it would be most appreciated.
Thanks.

Populating OUT parameters when TOO_MANY_ROWS exception is thrown

When I was trying to write code to test out today's PL/SQL challenge quiz, the behavior appears to depend on the table being queried. I can't figure out what attribute of the table drives the behavior (or if there is a different explanation for the behavior).
The quiz is testing what happens when a procedure does a SELECT INTO an OUT parameter and a TOO_MANY_ROWS exception is thrown. The intent is to show that even though the behavior is technically undefined, what actually happens is that the OUT parameter is populated with the first row that is selected (obviously, you would never write code that depends on this behavior-- this is solely an academic exercise). The demonstration code works as expected
CREATE TABLE plch_emp ( emp_name VARCHAR2(100) );
INSERT INTO plch_emp VALUES ('Jones');
INSERT INTO plch_emp VALUES ('Smith');
COMMIT;
CREATE OR REPLACE PROCEDURE plch_get
(out_name OUT plch_emp.emp_name%TYPE) IS
BEGIN
SELECT emp_name
INTO out_name
FROM plch_emp
ORDER BY emp_name;
EXCEPTION
WHEN OTHERS THEN
    dbms_output.put_line('A:' || out_name);
END;
What will be displayed after executing the following block:
DECLARE
l_name plch_emp.emp_name%TYPE;
BEGIN
plch_get(l_name);
dbms_output.put_line('B:' || l_name);
END;
/and outputs
A:Jones
B:JonesWhen I replicate the logic while hitting the EMP table, the PLCH_EMP table, and the newly created EMP2 table, however, I get different behavior for the EMP and EMP2 tables. The procedure that queries PLCH_EMP works as expected but the OUT parameter is NULL when either EMP or EMP2 are created. Any idea what causes the behavior to differ?

After all, the very same cursor is executed and the same PL/SQL engine uses that cursor interface.Clearly, there is something in my environment that is wonky. It just bugs me that I can't figure out what that variable is.
Your test was done as a single anonymous PL/SQL block. Which means each proc that was called referenced the same variable/memory - are there perhaps PL/SQL optimisation enabled for the database or session? Or any other settings that could influence the test? Have you tried calling the procedures directly from SQL*Plus using a bind var and not via an anon block and a local var in that block?I have. And the results were the same

As a sanity test - what happens when proc P3 for example is changed to a catersian join/union of emp2 and plch_emp? Do the test results change? Or you can change it as follows:

Of course, you can also put this one down to using an operating system like Windows as a poor database server and not as a magnificent client gaming platform... Well, sure. But you can probably only play World of Warcraft so long before you need to write some PL/SQL.

Exception Thrown When a Scheduled Task Runs for Many Hours

In the Oracle documentation here (http://download.oracle.com/docs/cd/E10391_01/doc.910/e10367/toc.htm#CACGBDAD) it states that the below exception can get thrown when a scheduled task runs for many hours (on OAS) and can be ignored:
Primary Server went down going to get a fresh object elsewhere in the cluster.
com.evermind.server.rmi.RMIConnectionException: LRU connection
Just want to find out from other users that get this error (If there is any), have you found the scheduled task actually completes, then the error is thrown or what?
I just don't feel comfortable that one of our tasks is completing properly due to this exception occuring and causing the task to stop midway through processing...

Hi,
I've had trouble with scheduling PowerShell scripts in the past as well. You can try running your script in the SYSTEM context by launching a cmd prompt this way, just to verify that the issue isn't related to the account itself:
http://myitforum.com/cs2/blogs/jmarcum/archive/2010/08/25/150872.aspx
This method does require PSExec, there's a link to the tool in the post if you don't already have it on hand.
You can also start PowerShell as SYSTEM and play around if you need to:
http://blogs.technet.com/b/ben_parker/archive/2010/10/28/how-do-i-run-powershell-exe-command-prompt-as-the-localsystem-account-on-windows-7.aspx?Redirected=true
Not the best answer, but hopefully it helps shed a little light on the issue.
Good luck.

Exception when upgrading server?

I am trying to diagnose a problem with my application which is a simple applet Swing GUI and servlet middle tier. The application was recently moved to a faster server and from a WinNT to Win2000 Server environment. The webserver was also upgraded from Netscape Enterprise version 4.1 to version 6.1. Suddenly I am now experiencing an Exception when the servlet tries to deserialize the Vector being sent from the client.
The GUI code for servlet connections and the servlet receiving code are pasted below. The EOFException stack trace is also below.
Please respond if you have any suggestions on solutions, work arounds, or any ideas that might narrow down the OS, Webserver, network, or code.
This exception is thrown at random times. Two successive calls with the exact same parameters may fail for one call but not the other.
To rule out the webserver, I have re-installed it and the error still occurs.
Originally JRE 1.4 was used by the upgraded webserver, however, I have switched back to JRE 1.3.1. Still no help.
I am beginning to wonder if Win2000Server might need to be re-installed.
Any comments are appreciated.
Thank you!

Timing could not have been worse for the upgrade. Of course it would have to be a microsoft problem.
