How to stop/kill/interrupt a thread stuck on reflection method invoke
Hi all,
I have a thread that loads some class using reflection and invokes a method in it.
I want to be able to stop that thread if needed by the user.
For some reason, interrupt on that thread doesn't do anything - thread is still inside the invoke call.
Is there any way to stop it?
The only really safe way to have isolated code is to a seperate process you can kill.
I wouldn't suggest using Thread.stop unless you have to, but that may be the case here. Stopping the thread this way might be worse than just discarding the Thread and moving on. (depending on what it is doing) i.e. another option is to ignore the thread and hope it doesn't matter. ;)
However, before you do that I suggest you call Thread.getStackTrace() and log it. This can be useful in diagnosing WHY your thread needed to be kill and possibly give you a chance to fix it next time.

How to 'STOP' a running java thread in J2ME?
Dear All,
How to 'STOP' a running java thread in J2ME?
In the middleware viewpoint, for some reasons we have to stopped/destroyed the running threads (we have no information how these applications designed).
But in J2ME, Thread.destroy() is not implemented. Are there other approaches to solve this problem?
Thanks in advance!
JasonHi jason,
Actually there are no methods like stop() and interrupt() to stop the threads in J2ME which is present in normally J2SE Environment.
But the interrupt method is introduced in Version 1.1 of the CLDC.
So, we can handle the thread in two ways.
a) If it is of single thread, then we can use a boolean variable in the run method to hadle it. so when the particular boolean value is changed , it will come out of the thread.
for eg:
public class exampleThread implements Runnable
public boolean exit = false;
public void run()
while(!exit)
#perform task(coding whatever u needed)
public void exit()
exit = true;
b) If it is of many threads then we can handle using the instance of the current thread using currentThread() method
for eg:
public class exampleThread implements Runnable
public Thread latest = null;
public Thread restart()
latest = new Thread(this);
latest.start();
public void run()
Thread thisThread = Thread.currentThread();
while( latest == thisThread )
#perform some tasks(coding part);
public voi d stopAll()
latest = null;
while ( latest == thisThread )
performOperation1();
if( latest != thisThread )
break;
performOperation2();

How to trap null return values from getters when using Method.invoke()?
Hi,
I am using Method.invoke() to access getters in an Object. I need to know which getters return a value and which return null. However, irrespective of the actual return value, I am always getting non-null return value when using Method.invoke().
Unfortunately, the API documentation of Method.invoke() does not specify how it treats null return values.
Can someone help?
ThanksWhat do you get as a result?I think I know what the problem is.
I tested this using following and it worked fine:
public class TestMethodInvoke {
public String getName() {
return null;
public static void main(String args[]) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException {
Object o = new TestMethodInvoke();
Class cls = o.getClass();
Method m = cls.getMethod("getName", (Class[]) null);
Object result = m.invoke(o, (Object[])null);
if (result == null) {
System.err.println("OK: Return value was null as expected");
else {
System.err.println("FAILED: Return value was NOT null as expected");
However, when I use the same technique with an EJB 3.0 Entity class, the null return value is not returned. Instead, I get a String() object. Clearly, the problem is the the EJB 3.0 implementation (Glassfish/Toplink) which is manipulating the getters.

How to Stop the process of Thread
Hi,
A process is running in a thread, which will create a file with records in it.
I have a cancel button and if I click the button, the process should be stopped i.e. it should not allow to create the file. Is it possible to do this?
If so, how to achieve this? Please help me in this regard...

Thanks in AdvanceThere is no (safe) way of just stopping the thread. What you can do is have a flag in your Runnable/Thread object that you flip when you click the Cancel-button. Then in your run() method you check every now and then if the flag has been flipped. If the flag has been set you stop what you are doing and do necessary cleanup.
Something along these lines should do it (this is just a skeleton code that won't compile, but the general idea should hopefully be clear):
class FileCreator implements Runnable {
private File file;
private boolean cancelled = false;
// Method to call when you click the Cancel-button
public synchronized void cancel() {
cancelled = true;
public void run() {
// Do whatever it is you need to do. On suitable places in the code you check if
// the job has been cancelled. E.g.:
try {
if( cancelled ) {
return;
// Create the file
file = new File(...);
if( cancelled ) {
return;
// Add the records to the file:
for( Record rec : getRecords() ) {
if( cancelled ) {
return;
addRecordToFile(rec, file);
// etc, etc
finally {
// Do necessary cleanup if the job was cancelled, e.g.:
if( cancelled ) {
if( file != null ) {
// The file was created before the job was cancelled. Delete it:
file.delete();
// etc, etc
// Somewhere else in your code:
FileCreator fc = new FileCreator();
new Thread(fc).start();
JButton btnCancel = new JButton("Cancel");
btnCancel.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
fc.cancel();
...Hope this helps! -
How to stop a daemon Java Thread?
If I have a thread set as daemon and the main program has already exited, how do I locate the thread to stop it?
Thanks.> As for stopping it you use a socket and send it a message. That of course would require another thread because it is a listener.
Could you explain me a little bit more this (or send a link)? That is probably what I want to do. I want to open another instance of the program and stop the running thread. (By the way I'm doing this on Windows).
Daemon thread != unix daemon.
I'm not actually setting the thread as deamon because I want it as a background task, but because I want the main program to exit after it has started the thread and I want the thread to keep running. I read somewhere that I could do this setting the thread as daemon. But I misunderstood what I read.
Again, what I want to know if there's a way of running an app that when you press a start button, for example starts a thread that performs some ops. and exits, but the thread is still running, and if you re-open the app and press the stop button it stops the running thread, that is, the instance of the app that created the thread is not the one who's going to stop it.
I don't necesarily want to do it using threads but that was the way I first thought of.
Thank you for your reply :)

How to stop killing database using all of pga
I have an application that is already written in java. It calls a package procedure
that has
inputs and outputs
This report kills the database and the dba noticed that it was eating all of the pga and killing the system. I am looking at the code and I see that one of the outputs is a
select ttype(col1,col2,...),tadtype(col1,col2...)
bulk collect into one of the output variables.
Just running a sample I noticed tha the bulk collect is collecting almost 30,000 rows and this ruinning in one session uses almost 250 mb of pga, when 10 users run the report the system dies. I have been told changing the java code will not happen. If there something I can do in the package to send the data back using bulk collect limit xxxx.
I tired using 1000, but the report only see the last 1000 rows. There are other output variables so I am not sure how to not "keep" all of the collection for this until I send it with the rest of the output variables. I am using 10.1.0.5. I am not sure if I can somehow write a function to pipe_row the rows backs to the client wirthout keeping the whole mess.
the psuedo code is something like this
procedure x (
pid IN s.SESSION_ID%TYPE
,piv_sort_on IN VARCHAR2
,piv_bno IN b.NO%TYPE
,piv_batch_type IN VARCHAR2
,piv_vt_cache_flag IN VARCHAR2
,potab_trans OUT TAB_TRANS
,potab_addr OUT TAB_ADDR
,pon_net_count OUT NUMBER
,pov_net_amount OUT VARCHAR2
,pov_currency_symbol OUT VARCHAR2
,pov_flag OUT TFLAG%TYPE
,pov_region_short_name OUT R.NAME%TYPE
,pov_error_msg OUT VARCHAR2
do work ...
huge bullk collect into ,potab_trans ,potab_addr -- about 20,000 - 50,000 rows want to change this
-- send output back and not keep the huge are for
-- these colllections.
more work for rest of output variable info
end

When running PL/SQL, you are using the PL engine - this engine makes calls to the SQL engine whenever it hits SQL in your PL/SQL code. Data has to be transferred between the PL and SQL engines. All this is pretty neat as it allows you to mix the source code of two very different languages, PL and SQL, combine it seamlessly, and treat it as if it is a single language. Makes development and maintenance and design and what not a lot better.
Each time your PL code uses SQL (opening a cursor, fetching from a cursor), that requires a context switch from the PL engine to the SQL engine. Context switching is unavoidable, but as it comes with a performance penalty needs to be reduces as far as possible.
Enter bulk collect. Instead of doing a 100 context switches in a cursor fetch loop to fetch a 100 rows, a single bulk collect can used to collect a 100 rows. 100 context switches versus 1 context switch.
Okay, but now where do that 100 rows go when bulk collecting? It has to be stored by the PL engine. The PL engine uses PGA memory. Thus it needs to allocate PGA to store these 100 rows.
If you bulk collect a 1000 rows, it needs to allocate PGA for a 1000 rows. If a million rows... ouch.
So a bulk collect decreases context switching. However, it increases the demand for PGA. It is therefore a balancing act when it comes to performance - decreasing context switching at the cost of an increase in PGA.
And this is why it is mostly mandatory that you use the LIMIT clause when bulk collecting. Bulk collect a 100 to a 1000 rows at a time. And as you are managing the number of rows that can be bulk collected per context switch, you are managing the amount of PGA to expend.
Last comment - you mention that the driving app is Java. Now I hope that this does not call PL/SQL, with PL/SQL doing a bulk collect, and then passing that collection back to Java. That is, plainly put, very stupid. Why?
The SQL engine has an excellent db buffer cache. Java can bulk fetch from it directly (one can set the array fetch size in an Oracle client driver). It makes absolutely no sense to use the PL engine as an intermediate cache - have the PL engine fetch rows from the SQL engine cache, cache those rows in (expensive) PGA memory, and then pass that to Java. It is a lot slower as it has more moving parts. It cannot scale as this design uses very expensive server memory called PGA as a cache - instead of relying on the SQL db buffer cache that was explicitly designed for this very purpose. -
How to stop/kill child process?
I am creating one process, and it will call another exe.
Now both are running as a different process. When I am closing my application first process is destroyed by calling destroy method. But I can’t able to close second process.
Thanks in advance.User845466 wrote:
thanks,
I have started my application by calling the first exe, then it will call second .exe.
when i close my application it is destroying first .exe it is not destroying the second one. Due to this when i run my app once again it is showing your application already running.This isn't a java problem at this point.
You have your "first exe".
You have your "second exe".
There are two possibilities.
1. There is something in "first exe" that allows it to terminate the "second exe"
2. There is no way to do that.
You must determine which of those it is. And that process has nothing to do with java.
If you determine that it is 1, then with that information you can then look to java to see if there is a way to invoke that. You cannot attempt to solve it with java however UNTIL you have the information.
If it is 2 then you are left with finding an OS specific way to do the following.
1. Locate the 'process' of the "second exe"
2. Use 'process' to kill "second exe"
Those steps have nothing to do with java. However once you know what those steps are it will be possible, but perhaps not easy, to implement via java (although still with OS specific functionality.) -
How to use java.lang.Class.getMethod() and java.lang.reflect.Method.invoke(
I want to call a specified method of one class dynamically. I use the method
"getMethod()" in package "java.lang.Class" to get method and "invoke()" in
" java.lang.reflect.Method " to invoke method.
The problem is as following :
1. There are two argument in this method "getMethod(String MethodName , Class[] paremterTypes)" in package "Class". I have no idea about the second parameter " Class[] parameterTypes ".what does the argument exactly mean ?
2. There are two argument in the method "invoke(object obj, object[] obj)" in package "Method".
I have no idea about the second parameter "object[] obj ".what is mean ?
I pass " null " value to it and it works.But i pass anothers ,jvm will throw exception.I have a generic Method Executer that has a method like
public Object execute(String className, String methodName, Object args)
String fullClassName = packageName + className ;
Class delegateClass = Class.forName(fullClassName);
BaseDelegate delegate = (BaseDelegate)delegateClass.newInstance();
Method method = null;
if (args == null)
method = delegateClass.getMethod(methodName, new Class[] {});
obj = method.invoke(delegate,new Object[] {});
else
method = delegateClass.getMethod(methodName, new Class[] {args.getClass()});
obj = method.invoke(delegate, new Object[]{args});
}This seems to have problems when I call the method from a class like:
execute("CategoryDelegate", "getCategoryById", new Integer(4144));(I get a NoSuchMethodException)
The method I am trying to execute in CategoryDelegate looks like:
public Category getCategoryById(int categoryId) throws DelegateExceptionI think it has to deal with the difference in the way we handle Primitive Wrappers and Objects. Wrapper we have to use Interger.TYPE and with the rest of the Objects we have to use obj.class.
Am I doing something wrong here? Any suggestions to make it work for primitive wrappers as well as Objects? -
How to restart an interrupted thread ?
Hi All,
I have to stop a thread and then restart it after sometime. Since, stop() method is deprecated in jdk1.3 so, I m using interrupt() instead of stop() method. Can anyone please tell me , what does interrupting a thread exactly means? Does it termainates a thread completely or not?
Because , if I use thread.interrupt() and then thread.start() just after it, it raises exception java.lang.IllegalThreadStateException but still starts the thread.
Prime concern is how to stop and restart a thread without using stop() method??
Thanx and regards,
ShwetaYou have to determine in the run method if the thread has been interrupted.
Usually like this
run()
while(!isInterrupted())
// code body
you could try this
boolean restart;
run()
while (true)
if (isInterrupted())
waitForRestart();
// code
waitForRestart()
restart = false;
while (!restart)
sleep(500);
restart(){restart = true;} -
Hello,
How can I kill a Swing thread? For example the program below would never exit. Sure you can type System.exit(0) which would exit anything, but what are the other solutions?
I tried putting chooser = null;
System.gc();in the end of main() but this won’t work.
To formulate my question better - how would I kill a thread I do not have complete command of (i.e. I can’t do usual do/while thread stopping)?
Big thanks in advance.
public class SwingLiveTest{
public static void main(String[] args) {
JFileChooser chooser = new JFileChooser();
if (chooser.showSaveDialog(null) != JFileChooser.APPROVE_OPTION) return;
File file = chooser.getSelectedFile();
System.out.println(file);
/*chooser = null;
System.gc(); */You can't kill any Thread like this, at least not those where there is no method to call.
It is possible to cause a Thread to stop, call the stop method, however this is not the recommended approach for very good reasons (Read the JavaDocs for java.lang.Thread.stop() method to see why.
It should be possible, once you have obtained a reference to the Thread you wish to stop, to call interrupt() on that Thread.
This is not guaranteed to work because you are dependent on the implementation of the Thread class you are manipulating or the Runnable that the Thread instance is currently running.
There may be classes in the com.sun packages which can aid you with this problem, this is where Sun usually sticks undocumented implementation however these packages are not officially supported and there is no guarantee that classes you use in one VM are available in another, in particular when the VM you are using is not a Sun VM. -

Threads getting stuck in reflection

Hello Forum,
A dataload was taking about 3 hours which usually takes 1 hour.
I've turned the request red and reran the load from Infopackage.
But while the new load was running, the request that I've turned red was also
updating the records.
My questions are:
1. Does it mean that the previous job was not stopped completely?
If so, please discuss how to stop/kill a job.
2. Are the steps same for full and delta loads?
thanks and regards,
rajHi,
In any case you need to force the request to red first , then ensure that in SM37 job log it is terminated and confirm by checking that the PID/WID is not active for the same job in SM66/SM50/SM51 and then delete the request from target and re trigger the load.
If its a datamart you need to reset datamart if its set and if its a delta it will ask for a repeat delta.
Ensure that this followed in your case also.
Hope this helps.
Thanks,
JituK -

I checked OS tcp_syn_retries, is 5, an exception should be raised after 180 seconds, isnt?
Even more weird is that sometimes a entityManager.find() give us null object even if the database record of the sougth persisted object exists.
It seems that we have a network problem here but WLS / JVM is not throwing exceptions so we cant show to network administrators this problem.
Our Weblogic is version 10.3.4 running on Redhat 5 with kernel 2.63.18-194.e15.
JDK reports itself as "Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)".
We have the exact replica of the faulty server (hardware and configuration) running the same application in the same domain connected to the same network switch connecting to the same Oracle instance but in that server we haven't suffer such problem.

I'd check in tools->embedded oc4j server preferences (current workspace app / data sources) and do a refresh now.
Next, make sure your app module config files reference the right connection by right clicking the app module and selecting configuration. lastly, make sure the project points to the right database connection by right clicking project -> properties, business components.
