How to do "java Program 50 7" when using Eclipse?

If you use the command-line environment to compile and run a java program called Sample.java instead of using Eclipse, you could compile by writing "java Sample 30 5" or replace the 30 and 5 with other numbers (lets suppose the Sample.java needs 2 int inputs). How would you do the equivalent of that when using Eclipse?
Thanks!

In the Run , there is an arguments tab ..

Java program stopped running when using JVMPI

Hi!
I'm writting a very simple profiler using JVMPI. I intended to pause/continue it by sending signal, like kill -SIGUSR2 PID, to it, but whenever I did this, the java program that ran with the profiler stopped running, however the profiler kept running properly.
Here's the code of the simple profiler and the testing java program.
//myprofiler.cc
#include <jvmpi.h>
#include <pthread.h>
#include <stdio.h>
#include <signal.h>
void sig_handler_pause(int);
static JVMPI_Interface *jvmpi_interface;
void notifyEvent(JVMPI_Event *event) {
switch(event->event_type) {
case JVMPI_EVENT_CLASS_LOAD:
fprintf(stderr, "myprofiler> Class Load : %s\n", event->u.class_load.class_name);
break;
case JVMPI_EVENT_OBJECT_ALLOC:
fprintf(stderr, "myprofiler>object alloc \n");
break;
extern "C" {
JNIEXPORT jint JNICALL JVM_OnLoad(JavaVM jvm, char options, void *reserved) {
fprintf(stderr, "myprofiler> initializing ..... \n");
// get jvmpi interface pointer
if ((jvm->GetEnv((void **)&jvmpi_interface, JVMPI_VERSION_1)) < 0) {
fprintf(stderr, "myprofiler> error in obtaining jvmpi interface pointer\n");
return JNI_ERR;
// initialize jvmpi interface
jvmpi_interface->NotifyEvent = notifyEvent;
// enabling class load event notification
jvmpi_interface->EnableEvent(JVMPI_EVENT_CLASS_LOAD, NULL);
fprintf(stderr, "myprofiler> .... ok \n\n");
signal(SIGUSR2,sig_handler_pause);
return JNI_OK;
void start(){
          fprintf(stderr,"start...\n");
     jvmpi_interface->EnableEvent(JVMPI_EVENT_OBJECT_ALLOC, NULL);
jvmpi_interface->EnableEvent(JVMPI_EVENT_CLASS_LOAD,NULL);
void pause(){
          fprintf(stderr,"pause...\n");
          jvmpi_interface->DisableEvent(JVMPI_EVENT_OBJECT_ALLOC, NULL);
jvmpi_interface->DisableEvent(JVMPI_EVENT_CLASS_LOAD,NULL);
int status=0;
void sig_handler_pause(int sig){
     if(status == 0){
          start();
          status = 1;
     else if(status == 1){
          pause();
          status = 0;
//Test.java
public class Test {
public static void main(String[] args) {
     try {
                    int i = 0;
while(true)
                         Thread.sleep(1000);
                    System.out.println(i++);
          catch (Exception e) {
                    e.printStackTrace();
Here're some notes:
1)If I didn't call
jvmpi_interface->EnableEvent(JVMPI_EVENT_OBJECT_ALLOC, NULL);
in "start()" function, the java program Test ran properly after I sent signal to the process by using kill command in an command line;
or
2) If I delete "Thread.sleep(1000)" in Test.java, then whether I call
jvmpi_interface->EnableEvent(JVMPI_EVENT_OBJECT_ALLOC, NULL);
in "start()" or not, the Test program ran properly after I sent signal to the process.
It seems to be a thread dead lock, but I'm not sure. Can any body help?Thanks very much.

I should strongly recommend moving from JVMPI to JVM TI if you can. The reason is that JVMPI has been deprecated since 5.0 and can not be used with Java SE 6 and newer.
Anyway, the issue you have may be due to the signal you are using. I'm not sure which operating system this is but on Linux the USR2 signal is used for the suspend/resume implementation. Have you looked at the Troubleshooting Guide or the Signal Chaining page for details on how signals are used and how to chain handlers? Another idea is to remove the signal handling code implementation and to use the data dump event. This is supported by both JVMPI and JVM TI so that you get an event (via the QUIT signal).

How can java programs execute automatically when it connects to network.What is "it"? That is, execute when what connects to the network?
Your computer? If that's what you mean, this is not a Java question. It's an OS operational/administrative question. Executing any program, whether written in Java or not, based on some system event has to do with that system, not with the program. If it's possible to do this, you'd do it exactly the same way for a Java program as you would for any other program.
Or is "it" the program itself? If this is what you mean, then it's a nonsensical question. For the program to connect to the network and detect that it has connected to the network, it must already be executing, so asking how to execute it at that point is meaningless.
Finally, I'll point out that "connecting to the network" is a pretty meaningless phrase. Or rather, it has so many potentially valid meanings that it's impossible to know which one you're referring to when you use that phrase. And I'd be willing to bet you don't have a clear picture of that yourself.

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

How to run java program from website?

Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
Cheers

I rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.

How to reach Java program which is run as individual process

Hi There .
My question is if I run a java program as individual process using Runtime , can I reach this process and change some variables up there, like set a boolean variable to false , or stopping running thread properly. whatever. till now I figure out two ways , either kill the PID of my program (if I want to stop it ), or touching a new file and when the program sense that the is been created he will take an action ,like exit or do the things that I want to do, I tried and I googled it but I ends up with nothing , what I understand it's like it's irreversible thing when it's run there is no way back. Thanks in Advance

No you can't interact with a process you start as if it were just other Java code.
What you can is interact with it in the same ways you can interact with any other process. For example through the process input and output stream. Or perhaps through Sockets.

How to set fetchsize of sql Query when using Database Adapter.

Hi All,
I am using DatabaseAdapter to connect to database and retriving huge amount of data.For improvement in the performance I want to set the "fetchsize" of sql query. I know fetchsize can be preset in Java using Jdbc 2.0 API.Please let me know how to set this value in BPEL when using DBAdapter?
Thanks
Chandra

I talked to the developer of the db adapter - and he told me this feature will be available in BPEL PM 10.1.3 (which is supposed to be production later this year, and a public beta soon). If this is an emergency I would recommend going throug Oracle support and have them file an enhancement for 10.1.2.0.2

How do images embeded in InDesign link when using Creative Cloud on more than two desktops?

How do images embeded in InDesign link when using Creative Cloud on more than two desktops?

If I am understanding your question correctly, you shouldn't have to worry about embedded images in InDesign. Once embedded, the image is stored within the file.
If you are wondering about linked images... InDesign will follow the path on your computer and, if it does not find the image, you will recieve a notification. Edit: To prevent this, I would suggest packaging your file using File > Package... This will create a folder with all of your fonts and linked graphics so that you need not worry about broken links. I just remembered that you cannot upload folders directly to Creative Cloud so a packaged folder wouldn't be very helpful unless you wanted to upload each file manually.
The best solution I see right now is to either embed the graphics in the document, or upload the images with your document to relink.
I hope this helped,
Michael

How do you update the Bios safely when using onboard RAID mirror? Z87-G45

How do you update the Bios safely when using onboard RAID with Z87-G45? I'm using a simple two drive, RAID 1 mirror setup.
I'm currently at bios 1.4, and want to move up. However, last time I upgraded the BIOS, the machine rebooted with improper settings for the RAID (they get hosed during BIOS flash) and Windows decided to auto-repair the only boot drive it could see, one half of the mirror, because it couldn't see the RAID array correctly and *POOF* bare-metal reinstall required.
My PC will not let me press the DEL key on bootup to access the bios, even with MSI Fast Boot not installed. It just ignores the DEL key and tries to load windows which, if that happens, will flame-out my RAID array after a bios flash if I can't catch it to enable the RAID first before windows loads.
I do not want to rebuild my PC again simply because I do a BIOS update.

FYI: BIOS 1.4 & 1.8 are using the same RAID version: 12.7.0.1936
based on this RAID surprise should not hapends.
But as pandaz says if you have no issues, leave bios update alone.
there are still risks something to messed up,
best do a backup of your data just in case if you want to try latest version
