Thread Callable call() method question

i am using callable interface and i need to return from call() method before process gets over.
basically i have infinite loop in call() method which gets data from streaming services,
and once i format the data and send back to EDT to update UI constantly.
i am using call() method because my call() (same as run() runnable) throws exception if there is any problem in receiving data.
i don't care for return value from call(). i only care if there is any exception.
if i don't do task.get().... then everything works fine, but then i dont get any executionException as well, (which i really care for)
FutureTask<String> task = new FutureTask<String>(resParser);
Thread thread= new Thread(task);
thread.start();
try{
String result = task.get();
}catch(ExecutionException e){
e.printStackTrace();
}catch(InterruptedException ex){
}any solution ??
Thanks

You will need to re-consider your requirements. You either call get() and block the active thread, or you let the thread continue to run and don't call get().
Your solution would be to catch the exception someplace else and feed the exception (or message) to wherever you need it. Why do you think you need to catch the exception right here (which is apparently in your EDT)? Why not catch it in the Thread's run method and deal with it there?

Java.util.concurrent.Callable synchronized call method

Hi all,
I'm currently developing an algorithm that uses Callable Interface. I'd like to know when should I use synchronized in the Call() method signature.
My scene is the following:
Class Test invoke Task Class.
The Task Class contains the following code:
                  ExecutorService execServ
                       =Executors.newCachedThreadPool();
                  CallableWorkerThread workers[]
                      =new CallableWorkerThread[numWorkers];
                  Future futures[]
                      =new Future[numWorkers];
                  for (int i = 0; i < numWorkers; i++) {
                       workers[i] = new CallableWorkerThread();
                         futures[i] = execServ.submit(workers);
The CallableWorkerThread class implements Callable and overwrite it's Call() method.
My doubt is about the following:
Should I use this:
public synchronized Object call() throws Exception {
        // Code to execute........
}OR
public Object call() throws Exception {
        // Code to execute........
}Tks.

Hi David, I thank you for your answer.
My class CallableWorkerThread implements Callable Interface because I'm using submit method() from ExecutorService.
In other words, when I use the instructionexecServ.submit(workers); the object workers must be a collection of Callable Objects.
This is my Test_CallableWorkerThread:
public class Test_CallableWorkerThread {
ExecutorService      execServ = Executors.newCachedThreadPool();
CallableWorkerThread      workers[] = new CallableWorkerThread[10];
Future                futures[] = new Future[10];
for (int i = 0; i < 10; i++) {
     workers[i] = new CallableWorkerThread();
     futures[i] = execServ.submit(workers);
This is my CallableWorkerThread:
public class CallableWorkerThread implements Callable {
     private Collection<MyObject> collectionOfMyObjects = null;
     private String threadName                   = null;
     private Connection conn                       = null;
     CallableWorkerThread(Collection<MyObject> collectionOfMyObjects, String threadName, Connection conn) {
              this.collectionOfMyObjects = collectionOfMyObjects;
              this.threadName = threadName;
              this.conn = conn;
     public Object call() throws Exception {
          for (Iterator iter = collectionOfMyObjects.iterator(); iter.hasNext();) {
               MyObject element = (MyObject) iter.next();
               System.out.println(this.threadName + " is working with " + element.getName());
               try {Thread.sleep((int)(Math.random() * 1000));
               } catch (InterruptedException e) {}
             return(threadName);
}According to the code above, I'm using CachedThreadPool. I read the documentation about this and this method creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available.
It's work fine, but until now I didn't undestand what is the real difference between using method with synchronized and without.
Thanks for the help!

How to call methods from within run()

Seems like this must be a common question, but I cannot for the life of me, find the appropriate topic. So apologies ahead of time if this is a repeat.
I have code like the following:
public class MainClass implements Runnable {
public static void main(String args[]) {
Thread t = new Thread(new MainClass());
t.start();
public void run() {
if (condition)
doSomethingIntensive();
else
doSomethingElseIntensive();
System.out.println("I want this to print ONLY AFTER the method call finishes, but I'm printed before either 'Intensive' method call completes.");
private void doSomethingIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
private void doSomethingElseIntensive() {
System.out.println("I'm never printed because run() ends before execution gets here.");
return;
}Question: how do you call methods from within run() and still have it be sequential execution? It seems that a method call within run() creates a new thread just for the method. BUT, this isn't true, because the Thread.currentThread().getName() names are the same instead run() and the "intensive" methods. So, it's not like I can pause one until the method completes because they're the same thread! (I've tried this.)
So, moral of the story, is there no breaking down a thread's execution into methods? Does all your thread code have to be within the run() method, even if it's 1000 lines? Seems like this wouldn't be the case, but can't get it to work otherwise.
Thanks all!!!

I (think I) understand the basics.. what I'm confused
about is whether the methods are synced on the class
type or a class instance?The short answer is; the instance for non-static methods, and the class for static methods, although it would be more accurate to say against the instance of the Class for static methods.
The locking associated with the "sychronized" keyword is all based around an entity called a "monitor". Whenever a thread wants to enter a synchronized method or block, if it doesn't already "own" the monitor, it will try to take it. If the monitor is owned by another thread, then the current thread will block until the other thread releases the monitor. Once the synchronized block is complete, the monitor is released by the thread that owns it.
So your question boils down to; where does this monitor come from? Every instance of every Object has a monitor associated with it, and any synchronized method or synchonized block is going to take the monitor associated with the instance. The following:
synchronized void myMethod() {...is equivalent to:
void myMethod() {
    synchronized(this) {
...Keep in mind, though, that every Class has an instance too. You can call "this.getClass()" to get that instance, or you can get the instance for a specific class, say String, with "String.class". Whenever you declare a static method as synchronized, or put a synchronized block inside a static method, the monitor taken will be the one associated with the instance of the class in which the method was declared. In other words this:
public class Foo {
    synchronized static void myMethod() {...is equivalent to:
public class Foo{
    static void myMethod() {
      synchronized(Foo.class) {...The problem here is that the instance of the Foo class is being locked. If we declare a subclass of Foo, and then declare a synchronized static method in the subclass, it will lock on the subclass and not on Foo. This is OK, but you have to be aware of it. If you try to declare a static resource of some sort inside Foo, it's best to make it private instead of protected, because subclasses can't really lock on the parent class (well, at least, not without doing something ugly like "synchronized(Foo.class)", which isn't terribly maintainable).
Doing something like "synchronized(this.getClass())" is a really bad idea. Each subclass is going to take a different monitor, so you can have as many threads in your synchronized block as you have subclasses, and I can't think of a time I'd want that.
There's also another, equivalent aproach you can take, if this makes more sense to you:
static final Object lock = new Object();
void myMethod() {
    synchronized(lock) {
      // Stuff in here is synchronized against the lock's monitor
}This will take the monitor of the instance referenced by "lock". Since lock is a static variable, only one thread at a time will be able to get into myMethod(), even if the threads are calling into different instances.

Can I Call method on one JVM from another through a dll?

Let me explain.
I have this java jar file that I can only have one instance of running at any given time. I'm using a shared data segment in a dll to store a bool indicating whether the program is already running or not. If it's already running, I have to not run the second instance and give focus to the current running instance.
The jar file calls a native method "canInstantiate()" on a dll to see if there's already an app running. If there isn't, the env and obj are stored in the shared data segment of the dll and we return true. If there is already an instance of the program running, I want canInstantiate call a function on the current instance of the jar (like a callback) to tell it to request focus. It's not working. Can someone tell me if my code is right?
The .h file
#include "stdafx.h"
#include <jni.h>
#include "CardServer.h"
#pragma data_seg("SHARED") // Begin the shared data segment.
static volatile bool instanceExists = false;
static JavaVM *theJavaVM = NULL;
static JNIEnv* theJavaEnv= NULL;
static jobject instanceObject = NULL;
static jmethodID mid = NULL;
static jclass cls = NULL;
#pragma data_seg()
#pragma comment(linker, "/section:SHARED,RWS")
jdouble canInstantiate(JNIEnv *env, jobject obj);
jdouble instantiate(JNIEnv *env, jobject obj);
jdouble uninstantiate(JNIEnv *env, jobject obj);
void grabFocus();
</code>
The .cpp file:
<code>
#include "MyFunctions.h"
#include <string.h>
#include <stdlib.h>
#include "stdafx.h"
#include <iostream.h>
jdouble canInstantiate(JNIEnv *env, jobject obj)

return (jdouble)0.0;
else
printf("An instance already exists!!");
grabFocus();
return (jdouble)1.0;
jdouble instantiate(JNIEnv *env, jobject obj)
printf("**In CPP: Instantiate!!\n");
cout << "At start, env is: " << env << endl;

Can I Call method on one JVM from another through a dll
...The rest of your question merely expands on your title.
And the answer to that question is no.
When you call a method you are executing a "thread of execution." A thread of execution exists only in a single process. It can not exist in another process.
If the dll is doing some interesting things then you could call a method that sets a flag. Data can move between instances. But you would then have to have a thread in that different process monitoring that flag. And sharing data in a dll is not a normal process, so it would have to be coded appropriately.
If all you want to do is set the current focus to the existing application, then that can be done with existing windows functionality. You don't need to do anything special in your dll. You can probably search these forums to find the exact code. If not there are countless examples in windows repositories (like MSDN) on how to do that.

How can I get the variable with the value from Thread's run method

We want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that scope of the variable gets lost resulting to null value in the called method/class..
How can I get the variable with the value?
This is sample code:
public class SampleSynchronisation
     public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run method "+sathr.x);
/* I should get:
Inside the run method
But I get only:
Inside*/
class sampleThread extends Thread
     public String x="Inside";
     public void run()
          x+="the run method";
NB: if i write the variable in to a file I am able to read it from external method. This I dont want to do

Your main thread continues to run after the sathr thread is completed, consequently the output is done before the sathr thread has modified the string. You need to make the main thread pause, this will allow sathr time to run to the point where it will modify the string and then you can print it out. Another way would be to lock the object using a synchronized block to stop the main thread accessing the string until the sathr has finished with it.

How to Call Methods in Ecatt?

Hello Gurus,
I dont find CALLMETHOD or CALLSTATIC commands in Ecatt. I am using R/3 4.7 version of SAP.
My question also is how to call methods. I have a scenario where my test script execution depends on the return type of method. Say if the return type of method is A only then I should run the script else the script should not be executed.
Your help in this regard is highly appreciated.
Regards,
GS.

Hi GS,
Please use the command "CallMethod" and it is available with latest SAP version.
You have to provide the Object Instance Parameter and Instance Method.

Pass Class Object To FMS Using NetConnection.call Method

Hello All,
I have a custom class that defines several methods on itself
to retrieve its data. This class object is then sent to FMS via the
NetConnection.call method. Once received by FMS, FMS calls the
remote method to dispaly the class object on connected clients
(minus the originator).
Now, standard properties are displayed correctly, but when I
call the class method to retrieve the class data, no data is
retrieved.
My question is, can FMS handle class objects as parameters in
a NetConnection call. If not, is there a better practice of
applying methods to retrieve the class data? Example below...
class com.QuizItem
var numOfAnswers;
var getAnswer;
function QuizItem(question)
this.numOfAnswers = 0;//<-- Returns correct number of
answers
this.getAnswer = function(answerNumberToGet)//<-- Does
not return any data when called by client side script
return this.answers[answerNumberToGet];//Already populated
array
Regards,
Shack

First, I know JAVA does not working "pass by
reference". It's only working pass by value. (or call
by value)But obviously you don't fully understand what it means.
Isn't main_a and method_a alias?
if there is not alias, why? please explain to me.No. They're two independent references coincidentally pointing to the same object. In your swap method, you move method_a to point to something else. This does not affect main_a.
and why main_a.hashcode() is main_a's value?why not? What else should it be?
I think It's mean copy object. but main_a and
method_a, they have same object id! @_@;;;It means "copy reference", same object.

Hi Experts,
I have one requirement...
I have 2 components A and B, i used A comp in B, i need to call Comp A methods in Component B, can anybody give me the syntax?? please...
Thanks and Regards,

Hi Manas Thanks for your fast reply,
My question is, for example we have wd_comp_controller or wd_this objects to call methods of view from view and comp controller right.. like this we have any methods to call used component methods? if yes can u please give me the objects syntax?...

Alternatives to long parameter lists when calling methods

I've heard you shouldn't have more than 3 parameters when calling methods. What are the alternatives to long parameter lists when calling methods? Compounding parameters into new inner classes, declaring them as member fields? Which one is preferable?

Okay, I get it. But since it's late in the day, I'll share my additional wandering thoughts. And I'll just go ahead and preemptively slap myself for doing so. Ouch! There. So the rules are more like this:
1) Only use setters if the values in question are meant to be part of the state of an object.
2) In general, don't let external entities directly set the state of an object.
Which can be combined into:
1) In general, never use setters.
Which could be reworded to:
1) Only use setters in non-general situations.
Or:
1) Only use setters when setters are a good solution...which isn't very often...generally speaking...
Or if I were to infer when it's a good solution:
1) Only use a setter when it is useful to the caller and has no significant negative effects on the operation of the object nor the maintainability, size, or performance of the class...generally speaking...
Actually, you might just infer from here forward that the "generally speaking" is implicit to every rule, and is essentially the "There is an exception to every rule" rule. Which is an interesting rule because it can be applied to itself, resulting in a paradox...generally speaking...but I digress.
And then translated back to the original topic:
1) You can use a setter instead of a constructor argument so long as the value isn't needed at time of construction (or a default value will suffice) and it is useful for the caller to be able to use the setter and using the setter has no significant negative effects on the operation of the object nor the maintainability, size, or performance of the class.
But this won't quite cut it either. With the input of others, we could eventually devise a very concise rule, but it will end up being so long that on one will ever read it...making it an ideal candidate to be included in a legal document. Which will eventually find it's way into a very long scroll pane with a check box at the end exclaiming that you read the document, at which you will not be able to continue unless you check the check box...at which point, what do you do? After all, you are not a liar...generally speaking...
In summary, you could potentially use setters in some limited cases, but in the general sense, that's more of an option than a recommendation. :-)

It's throwing an exception because at some point, you are not checking
your string for nulls before calling replace. My guess is that
this.RXMap.REQUEST_TM is sometimes empty/null and when you call replace,
it then excepts. Always ensure that your string value is
non-null/defined before calling a function against it.

Oop report programme: call method

hi, i need ur guys advice about my oop report. its contain 2 class, lcl_main (main programme), lcl_disp(display report), lcl_update (upload report). all 3 class defination as below:
*                     C.L.A.S.S D.E.F.I.N.I.T.I.O.N
class lcl_main definition.
public section.
methods: init,
           get_filename,
           load_data,
           chk_col,
           chk_data,
           chk_mandatory,
           disp_status.
endclass.
class lcl_disp definition inheriting from lcl_main.
public section.
methods: chk_9700,
           disp_success.
endclass.
class lcl_update definition inheriting from lcl_main.
public section.
methods: update9700.
endclass.
the idea was, i planned to put all methods which will be access by lcl_disp and lcl_update into lcl_main. i currently cofious to call method at lcl_main. currently i done as below, which if want to display (user will choose radio button display - p_view) i will create the object for lcl_disp and call all method in lcl_main and lcl_disp , for example o_disp-> init ... o_disp->loaddata .. and etc. the problem was if i want to choose the update , i need to object for lcl_update and call again the lcl_main with: o_update-> init ... o_update->loaddata .. and etc. the code as below.
the question , the programme can be successfully run with this method but i faced the problem when i tried to create a call method inside others method because at the START-OF-SELECTION i need to identify with object (lcl_disp or lcl_update) first.
2nd, i tried to figure out how at the start-of-selection , i no need to repeat to call method init, loaddata repeatly for different class (lcl_disp and lcl_update). really need advice. thank you.

Hello Sam,
Go to the class CL_DD_DOCUMENT (trxn SE24).
In the 'Attributes' tab, check for the attributes with SDYDO_ATTRIBUTE as the associated type.
It gives all the available attributes.

Can a WAR call methods in a 'Parent' jar?

With oc4j, can I designate a jar containing ejb's (2.1) as a parent of a war file that has servlets which call methods on the ejb (via jndi lookup)? I want to accomplish this without an ear.
I am considering migrating from JBoss and for some reason JBoss let's me get away with this. This would ease migration substantially.
Thank you all;

I have a question here..
Will reconfiguring iAS to use J2SE 1.4 conflict with Oracle Portal (9.0.4). I mean we have everything running smooth for Portal so we want to make sure that reconfiguring iAS for J2SE 1.4 won't have any affect on Portal.
I hope you can reply me on this or refer me to some other document.
Thanks in advance.

Spry and Permission denied to call method XMLHttpRequest.open

hi all,
I'm using Spry to call an RSS feed and display on a webpage.
I'm running this locally on my computer for testing measures and it
works fine in IE but i'm getting a message saying "Permission
denied to call method XMLHttpRequest.open" when using FF.
I googled around a bit and found that it has to do something
with FF's cross domain security, but nothing much more than that. I
was just wondering if anyone would be able to point me to a good
resource that explains the issue more and how to fix it, keeping it
in mind that i want to fix it using Dreamweaver's Spry
options.

You're right that there should be no problem with a local
file, but
without seeing the XML file and your code, it's impossible to
say what's
causing the problem. I think your best bet is to post a more
detailed
question in the Spry forum.

Calling method from SWF file wtih javascript, when swf file is not loaded in any browser

Hi There,
I have a question regarding flex and javascript integration:
1. We have created certain components and bundle them in swf. these swf file uses webservice to connect to backend code written in java.
2. We have deployed swf file and backend on the same tomcat server.
3. Backend server send some datapoint to UI and plot graph and displyaed to user.
4. Now if user generate graph from datapoint and want to export it, we are tranferring image of that graph from UI to backend. No issues in this process.
5. Now the question is. let say user has not open any swf file in browser and backend scheduling job want to generate the graph. How we will connect to swf file.
6. Is ther any way we can connect or call method of swf from java/jsp/html/javascript code in this scenario without loading swf file in browser??
Please help me!!!
Thanks
Sonu Kumar

Both test sites work just fine for me.
The "Update plugin" message is exactly what would be displayed if no .swfobject file at all was found... so it may not be the "version11" thing but rather, perhaps something else is messed up with the .swfobject file.
File can be found in both folders:
http://www.pureimaginationcakes.com/test/Scripts/swfobject_modified.js
http://www.pureimaginationcakes.com/Scripts/swfobject_modified.js
and file does download when downloading the html page (just check the cache).... but for some reason it doesn't seem to be working.... Hummmmm????
