Threads (Java 6)

Hallo all,
I am quite new to threads and I have a problem. I am having a Swing application which has to show a text for 10 seconds and then it should disappear. I cannot send a code right now but can anyone tell me if how I can do it?

So what I did is like this
descriptionLabel.setText(res.getString("Structure.saved"));
                            timer = new Timer(20000, this);
                            timer.setInitialDelay(10000);
                            timer.start();
                            timer.stop();
                            descriptionLabel.setText(res.getString(""));But id doesn't work. What I want to do is to show the text and give a 10 seconds delay and then show the second text. What am I doing wrong here?

You've got to have the WebLogic JAR that contains the necessary .class files in your CLASSPATH when you run.
Don't use a CLASSPATH environment variable; use the -classpath option when you run.

Hi,
I have an application jar file which is run from a .sh file.
The application uses ridc api to checkin a document on UCM.
I have placed jars for supporting the application on the folder where we have kept the application jar
also we have mentioned the supporting jar file names in the Manifest.mf file of the application jar.
The necessary jar files which we have placed are:

I encounter the similar error. Anyone knows how to fix it?By providing a configuration file which validates with the corresponding XSDs found in coherence.jar. Sorry, but can't point you to the specific issue without seeing the erroneous configuration file.

I can not see main class weblogic.jar file in your class path.
Under MW_HOME there is a file by name configure.cmd/sh, run it to set acl and class path. Then try to start weblogic server. U can edit the startWeblogic.sh/cmd so that every time it will execute after calling configure.sh/cmd file.

Any Ideas??

Well, have you run the app with logging set to fine as the message suggested?
Turn on fine level logging for a stack trace of this call. Component ID: {0}
Then a test case and a detailed description on how to reproduce the error, built on the hr schema, can help.

JSP generates error - thread.java:481 - Source code viewing is disabled

I run IBM WebSphere 3.5.3 on a WinNT platform. When I try to run my JSP testpage (which is a normal HTML page with jsp extension) I get the error message:
thread.java:481 - Source code viewing is disabled.
What is this? What can I do to get it running?
I have made the webapplication and application server and it seems to run fine.
Thanks in advance.

I thought I had done it correctly, but I must have missed out on something. I tried my jsp code in the "examples" folder and it worked there. I am now using the "examples" folder instead. Thanks for your reply :)

Again you need to make a difference between what runs within the weblogic container to what runs in a vanilla JVM. Understanding this is crucial to your problem.
1. web service -> client -> another web service
The webservice will always run within the weblogic container and you should never get the ClassnotFound because weblogic.jar is always available there. Any subsequent clients loaded into the same JVM will presumably be in the same classloader and wont have problems either
2. client -> web service;
If you are using a standalone client in a JVM you shouldnt have any dependency on weblogic and commons-httpclient will work just fine as would commons-logging. However if you include some weblogic jars in the classpath, when you launch the client JVM you would need to include the jars mentioned in the other post because they reference other weblogic classes. But this isn't necessary if you just clean up your classpath to only have the jars you need.

Error thread java : problem with the function "resume 0x***" (forum sun)

One problem with the function of jdb occured when I tried to use it to
pilot the processor with differents threads. In fact, I use a simple example with 2 threads.
I stop the two threads with two breakpoint, and I want to resume one or the other (with the function "resume 0x****"), the one wich I resumed stop again on the breackpoint and I decide again to resume one or the other. All of that to obtain a tree of execution.
I give you the code of the class and the code of jdb.
CLASS: (it's just a object Room with a variable degre that I increment and decrement with two threads increase and decrease)
public class Test{
     public static void main(String[] args){
          Room r = new Room();
          decrease de = new decrease(r);
          increase in = new increase(r);
          de.start();
          in.start();

Hi,
I have read the FAQ of the JMF.
The problem was the jar files of the JMF were not in the JRE\BIN\EXT
folder of the Java runtime!
now it works!

Finalizer Thread - java.lang.rOperating System

Can anyone please help me understand what is being conveyed by the finalizer portion of a thread dump:

I have been unsuccessful in finding any information on how java.lang.rOperating System comes into play. When our finalizer thread looks like this within the thread dump, the Reference Handler and Signal Dispatcher threads do not appear at all within the dump. The thread dump is from a web application using JRun with IIS serving the web pages.

11.5.10.2 & Sun T5220 & threads & Java garbage collection...

We recently upgraded our prod and test servers (middle tier) to Sun T5220's each with 8 procs which have 8 cores per proc. Apache/Java sees that as having 64 CPUs and configures a garbage collection thread for each. Since we have around 10 test and dev instances for the HRMS the apps instances alone, (we also have several Financials instances on the same server), it was kicking off over 640 threads of garbage collection! Needless to say the contention was overloading the server causing major hassles. We have since updated each $CONTEXT_FILE ADJREOPTS and ADJRIOPTS settings to only kick off 2 threads per instance. This has helped, but we still have issues, especially when running adadmin or adpatch and if we give it more than 8 workers. Has anyone else seen this, and if so, have you had any other solution(s)?
We are also seeing strange behavior with FNDSM. Unlike the production server, which has much less load in some respects, on the test sever, each apps instances instance of FNDSM is restarting several times a day for no apparent reason and leaving many defunct child processes. We do see a slight hangup in the tnsping to the FNDSM_<server> listener every so often, but never anything long enough that it should be an issue. We also have multiple NICs on the box, but again, that has never been an issue before.
Anyone else out there using Suns T5220s? Anyone else having any issue(s) with Apache/Java and / or FNDSM?
thanks,
-mike

It appears to be a known issue for the Niagara chips:
Oracle Applications Installation and Upgrade Notes Release 12 (12.0.4) for Solaris Operating System (SPARC)
http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=402312.1
Java Performance on UltraSPARC T1/T2 (Niagara) processors
There is a known issue with the Java Runtime Environment (JRE) version 5 on Sun's Niagara processor, a one-socket 8 core processor that can run 32 threads in parallel. As the JRE treats the Niagara system as a server class machine, the server appears to the JRE to be a 32-CPU machine and each Java Virtual Machine (JVM) spawns 32 garbage collector threads. Also, newer chips support a larger number of threads (for example, the Niagara 2 will appear as a 64-way server).

Tracking a separate Thread - java/jsp/struts

Hi all,
My project is a webapplication using java/jsp/struts. My requirement is to write bulk data to a file, which i want to run as a separate thread. Since it runs as a separate thread the control comes back to UI (userInterface) page. On subsequent request from UI page by the user i want to check whether the thread process is completed or not , so that i can read from the file. Is it possible to simultaneously read from the file when the thread is in the process of writing data to the file. If so any idea on how to implement this functionality in java?
How to keep track of the separate thread (whether it is completed or not) in java?
Is it possible to read from the file when the thread is writing to the file in java?
Thanks is advance.

As you're already asking this trival question, I highly recommend you to read the Concurrency Tutorial here at Sun.com. Google can find it.
Is it possible to read from the file when the thread is writing to the file in java?Not with java.io. You can use the java.nio API for that. You can also read/write it in memory (as a byte[] or a ByteArrayInputStream/OutputStream property) and if it is finished then write it to disk.

Multi-threaded java application and deadlock down in Oracle library

Hello,
I was running our Java (JDK 1.6_14) application from Windows XP hitting an Oracle (10g) instance on Linux and came across a deadlock issue with two (of 10) threads. Below is the stacktraces (based on Java thread-dump at the command line). This code I've run 30-40 times with no problems of deadlocks.
The Oracle library that we're using for our Java application is ojdbc14.jar and sdoapi.jar (for spatial).
We create our Connection as follows (for each thread -- 10 of them):
public class Worker implements Runnable
private Connection _Conn;
public Worker(...)
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
_Conn = DriverManager.getConnection(url, username, password);
_Conn.setAutoCommit(false);
The code that is already executing these same lines below was already executed by other threads (in their own instance of Worker). So this is very confusing.
Any ideas? Version of the .jar files? Place how we're calling "DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());"?
Thanks, Jim

Thanks Toon for your reply.
Yes each Worker (executing in their own thread) has their own instance of Connection as per the Constructor (shown in original post). That is why this is weird.
I'll check the v$session when I get into work.
Based on our code that I put in the original email, Connection is a non-static variable. We have a per Thread per instance of Worker of which that Worker instance has its own instance of Connection. So I'm wonder if the following needs to occur:
Both of these lines (from original email) need to happen in the main thread as follows:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
for (i=0;i<NUM_OF_WORKERS)
_Conn = DriverManager.getConnection(url, username, password);
new Worker(_Conn);
Thanks,Jim

Synchronizing unrelated threads - java.lang.IllegalMonitorStateException

Hi,
I'm trying to synchronize two unrelated threads using a third object, but getting java.lang.IllegalMonitorStateException: current thread not owner error. Does any one know what am I doing wrong and how to fix it. A simulated code is posted below.
Thanks in advance.
// ----------- beginning of code --------------------------
// Code that throws java.lang.IllegalMonitorStateException: current thread not owner error.
public class ThreadTest
public static void log( String message )
     System.out.println( Thread.currentThread().getName() + ":" + message );
public static void main( String args[] )
     Thread thread1 = new Thread1();
     Thread thread2 = new Thread2();
     thread1.start();
     thread2.start();
     try
     thread1.join();
     thread2.join();
     catch (InterruptedException e)
     e.printStackTrace();
     log( "All Done...");
class Thread1 extends Thread
public void run()
     synchronized( Common.done )
     while (!Common.done.booleanValue())
          ThreadTest.log("Waiting on Common.done");
          try
          Common.done.wait();
          catch (InterruptedException e)
          e.printStackTrace();
class Thread2 extends Thread
public void run()
     synchronized( Common.done )
     ThreadTest.log( "Sleeping for 10 seconds ");
     try
          Thread.sleep( 10 * 1000 );
     catch (InterruptedException e)
          e.printStackTrace();
     ThreadTest.log( "Calling notifyAll");
     Common.done = Boolean.TRUE;
     // ******* Why am I getting 'java.lang.IllegalMonitorStateException: current thread not owner' in the next line
     Common.done.notifyAll();
class Common
public static Boolean done = Boolean.FALSE;
// ----------- end of code --------------------------

// ******* Why am I getting'java.lang.IllegalMonitorStateException:
current thread not owner' in the next line
Common.done.notifyAll(); Because x.notifyAll() has to be inside a
synchronized(x) block.
The code you posted looks like it meets that
criteria, so I would have to conclude the code you
posted does not represent the actual code you are
running.Hi.. It is inside synchronized( Common.done) block... Thats why I'm confused....

Cannot get bitmap from native DLL from multi threaded Java app.

I have a native DLL that gives me a HBITMAP (Windows handle to bitmap). I have made a JNI wrapper for this that gives me a BufferedImage back. The native code simple gets the actual bitmap for the handle, converts the RGB byte triplets to RGB ints, puts this in a jintArray and creates a BufferedImage.
This all works fine within a single Java thread. If I do this multi threaded (thread 1 calls the native function and several seconds later, thread 2 calls the native function) I keep getting the last image of the first thread. Can enyone help me out?
I know that this is probably a question for MSDN but I just know that they will tell me its a JNI question.
The native code:
JNIEXPORT jobject JNICALL Java_somenamespace_getPicture
(JNIEnv *env, jclass cl, jstring serialNumber)
jobject jImage;
jclass jImageClass;
jmethodID jMethod;
jfieldID jField;
jintArray rgbArray;
char *str;
char *charArray;
int *intArray;
int w, h, index, type;
HBITMAP hbmp;
BITMAP bmp;
str = (char*)((*env)->GetStringUTFChars(env, serialNumber, NULL));
// Gets the HBITMAP handle from the native DLL. The first argument is to select the device, based on serial number.
getPicture(str, &hbmp);
(*env)->ReleaseStringUTFChars(env, serialNumber, str);
// Get the BITMAP for the HBITMAP
GetObject(hbmp, sizeof(BITMAP), &bmp);
// Create my BufferedImage
jImageClass = (*env)->FindClass(env, "java/awt/image/BufferedImage");
jMethod = (*env)->GetMethodID(env, jImageClass, "<init>", "(III)V");
jField = (*env)->GetStaticFieldID(env, jImageClass, "TYPE_INT_RGB", "I");
type = (*env)->GetStaticIntField(env, jImageClass, jField);
jImage = (*env)->NewObject(env, jImageClass, jMethod, bmp.bmWidth, bmp.bmHeight, type);
// Get the RGB byte triplets of the BITMAP
charArray = (char *)malloc(sizeof(char) * bmp.bmHeight * bmp.bmWidth * 3);
GetBitmapBits(hbmp, sizeof(char) * bmp.bmHeight * bmp.bmWidth * 3, charArray);
// Allocate space to store the RGB ints and convert the RGB byte triplets to RGB ints
intArray = (int *)malloc(sizeof(int) * bmp.bmHeight * bmp.bmWidth);
index = 0;
for (h = 0; h < bmp.bmHeight; ++h)
for (w = 0; w < bmp.bmWidth; ++w)
int b = *(charArray + index * 3) & 0xFF;
int g = *(charArray + index * 3 + 1) & 0xFF;
int r = *(charArray + index * 3 + 2) & 0xFF;
*(intArray + index) = 0xFF000000 | (r << 16) | (g << 8) | b;
++index;
// Create a jintArray for the C RGB ints
rgbArray = (*env)->NewIntArray(env, bmp.bmHeight * bmp.bmWidth);
(*env)->SetIntArrayRegion(env, rgbArray, 0, bmp.bmHeight * bmp.bmWidth, (jint*)intArray);
// Use BufferedImage.setRGB() to fill the image
jMethod = (*env)->GetMethodID(env, jImageClass, "setRGB", "(IIII[III)V");
(*env)->CallVoidMethod(env, jImage, jMethod,
0, // int startX
0, // int startY
bmp.bmWidth, // int width
bmp.bmHeight, // int height
rgbArray, // int[] rgbArray
0, // int offset
bmp.bmWidth); // int scansize
// Free stuff
(*env)->DeleteLocalRef(env, rgbArray);
free(charArray);
free(intArray);
return jImage;
}I already tried working with native HDCs (GetDC, CreateCompatibleBitmap, SelectObject, GetDIBits, ...) but this just complicates stuff and gives me the same result.

Have you verified what the "native DLL" gives you back on the second call?The HBITMAP handle returned is the same each call (no matter which thread). The actual BITMAP associated with this handle is only updated in the first thread.
How are you determining that the image is the same?If I point the camera (I don't get a stream, I just get individual images) to a moving scene, I get different images for each call from within the first thread. The second thread only gets the latest image from the first thread. There is no concurrency of the threads and all methods are synchronized.
Specifically did you verify that the problem is not that your test code itself is using the same instance?Yes, I tested the native side as well as the Java side. The BufferedImage is always an exact copy of the native BITMAP.
Try printing out the hash for each instance.I have written the image to a file in the native code itself to eliminate anything related to the mechanism of returning the BufferedImage. This had the same result.
The return values of all native calls all indicate successful calls.
I am suspecting the native side of creating a second graphical context for the second thread while it keeps refering to the first context.
(I will start a thread on the MSDN as well and will post here if anything turns up.)
