Native function call halting my program execution...
Well, I successfully got a an audio DLL made with JNI/SDL. This little program basically just runs until it finishes a song, then terminates.
Problem is that the program waits for it to finish.
I tried this:
class MusicThread extends Thread{
public native boolean startMusic();
public native void endMusic();
public MusicThread(pumpkin owner){
super(owner);
public void start(){
startMusic();
}Hoping it would cause Java to run the thread seperatly, but that doesn't work. The only thing I can think of is having the DLL itself open the new thread, but I would like to explorer java options first.
Is there some way I can get it to not wait until my DLL function stops running to continue?
Does it have to be done on the C++ side?
Alright, everything up and working.
I can't believe how helpful this board is. Thanks to you guys I have an increasingly impressive looking game that will soon have an entire SDL sound library!
Thanks a ton!

I created a native c class which is called in a java code. when i try to execute the program , there is "java.lang.UnsatisfiedLinkError". I tried to place the dll file created in the appropriate directory, but still i get the same error.
My java class( which tries to access the c class) is in a package which is inside another directory, will this create any problem?
kindly help me with ur suggestions. thank youI am attaching the code fragments below:

Exit handling in native function by JNI
Hi everyone,
We are developing a Java application using native function calls through JNI in Linux.
The application starts and calls a native function and the native function attach a signal
handler and an exit handler. In addition, in the native function, we fork another process
and in the forked process, we calls a several java-side methods. It works in normal cases.
However, when System.exit() is called in the java-side methods invoked by a native function,
the application is stopped. Thus we add shutdown hook (Runtime.getRuntime().addShutdownHook())
to treat this case. The shutdown hook just calls a native method, and the native method
just calls exit(). We expect the calling exit() in the native method invoked in shutdown hook for JVM
invokes our exit handler which is attached in advance. It looks working well.
But, sometimes we find several garbage(?) jvm processes (we can see the process named as "java"
in using Linux command "ps"). The parent process of these processes is init process (pid = 1).
With the pid of these processes, we suspect the processes are created when we fork another process
in native function invoked through JNI. However it is not happened every times in our application.
Why the garbage java processes remain? Is there any problem in the calling exit() in the native
method invoked during JVM Shutdown process?
I hope any answers for this problem.
Thanks in advance,
Seung-Uk OhThus we add shutdown hook
(Runtime.getRuntime().addShutdownHook())
to treat this case. The shutdown hook just calls a
native method, and the native method
just calls exit(). We expect the calling exit() in the
native method invoked in shutdown hook for JVM
invokes our exit handler which is attached in advance.
It looks working well.I wouldn't think that was a good idea.
You are terminating the JVMs normal exit process. Why don't you just register the exit processes in your own stack and call them with the native method? -

UnsatisfiedLinkError with function call
Hi,
I am using JNI to make native function calls from Java.
I use
System.loadLibrary("myLibName");
to load my library, and that works without a problem.
I can use this library without any problems from a simple test app I wrote. However, I get an UnsatisfiedLinkError when I try and integrate with the rest of my applicaton. I am 100% certain that function is defined correctly in both Java and C++.
The only difference I can think of between my real application (which does not work) and my test application (which does work) is that in my real application, the object that makes use of the class that contains all my native methods is cloned before it makes any calls to my native code.
What can cause an UnsatisfiedLinkError if my System.loadLibrary() is correct, and my function definitions are also correct?
Thanks!
Eliott
Edited by: EliottH on Mar 1, 2010 12:17 PMIn case my post needs any clarification, here is some sample code that demonstrates what I am doing:
//An instance of this class gets cloned before any native function calls are made!
public class SomeClass implements Cloneable {
JniClass jniclass;
SomeClass() {
jniclass = new JniClass();
//This returns an UnsatisfiedLinkError when called
public void func() {
jniclass.nativeFunc1();
public void clone() {
//Something....
public class JniClass {
public native void nativeFunc1();
static {
System.loadLibrary("myLibName");

SNMP4J- where is processPdu called in the program?
Hello Everyone,
Ive made the simplest possible agent just to check if it can respond to the PDUs received from the manager. Although Ive written the following code with the help of the SNMP4J tutorials, I have my doubt as to where is the processPdu function called in the program?

Please tell me where Im going wrong. Also, since i'm working on Eclipse IDE, it seems quite confusing to me how to execute manager and agent together in order to create a communication session( just da way v do in socket programming). it seems that i can only run either of them at a time..

The order of execution (of PL/SQL function calls) changes...why??
select e.EMPID empid,
e.name name,
aatest.SETVALUES(2) z,
aatest.TEST1() b,
aatest.TEST2() x,
aatest.TEST3() y
from emp e
where e.empid = 101
order by e.name;
when I execute this select statement...the order of function calls is as follows:
setvalues 1st (call no:1)
test1 (call no:2)
test2 (call no:3)
test3 (call no:4)
Now...I introduce a join between the two tacles as mentioned in the query
select e.EMPID empid,
e.name name,
e2.deptno deptid,
aatest.SETVALUES(2) z,
aatest.TEST1() b,
aatest.TEST2() x,
aatest.TEST3() y
from emp e, emp2 e2
where e.empid = e2.empid
order by e.name;
The order of execution of function calls changes to
(I observed this using DBMS_OUTPUT.PUT_LINE)
test3 (call no:1)
setvalues 1st (call no:2)
test1 (call no:3)
test2 (call no:4) (the first and last calls swap!)
i.e: it calls the last function in the select statement at the beginning
instead of calling it at the last. Is it the normal behaviour? or whats going on
here?
Can somebody explain me, please....
Details:
the following four functions are defined in a package called 'aatest' and compiled.
aatest.SETVALUES(2)
aatest.TEST1()
aatest.TEST2()
aatest.TEST3()
the Tables EMP and EMP2 are two tables defined in the same schema.Your "thinking" is wrong here. You can not use the column order to model your program flow. As SQL is set/tupel based, there is no given sequence of the execution order. Otoh you want to have a specific order in wich your functions must be executed otherwise the result will be wrong (or undefined). Thus here you need a procedural approach. This can be done by using PL/SQL for example.
You would code your functions in that way, that they are working correctly independent from the place where they are called ie if function1 needs the setvalues function, this function must be called inside the function1 then.
Are you sure you need all these functions in this procedural approach inside the sql-statement? This is mostly not needed and can be accomplished by using pure SQL. If not, may be your design is broken. -

Call native function fflush & strprn from java
Hi,
I need to call a native function fflush and stdprn from java for printing a file.
How can i call this function?
Can any one help me with sample code.
Thanks,
rpalaniveluThanks your reply,
Actually my problem is need to take printout using dot matrix printer(text printer) with different font size.
So, i am using native method which is available in c.
in c program i am using fflush,stdprn and fprintf.
Here i've attached my sample program also.
#include <jni.h>
#include "NativePrint.h"
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define MAXLINE_LEN 100
JNIEXPORT jint JNICALL

FILE *fp;
char filename[20];
char line[100]; /* A line read from the file */
int lineNumber = 0;
/* Print control codes */
char boldOn = 14;
char boldOff = 20;
char contentlenOn = 15;
char contentlenOff = 18;
printf("Printing from C3");
strcpy( filename , "sayHello.c" );
/* Open the file in read mode */
fp = fopen( filename , "r" );
/* Error in opening file, then exit */
if ( fp == NULL )
printf( "\nERROR: %s cannot be opened\n" , filename );
exit( 1 );
while ( fgets( line , 100 , fp ) != NULL )
lineNumber++; /* Line we are about to process next */
printf("%s",line);
/* If this is the first line */
if ( lineNumber == 1 )
/* then print it in bold */
//fprintf( stdprn , "%c" , boldOn );
fprintf( stdprn , "%c" , contentlenOn );
fprintf( stdprn , line );
fprintf( stdprn , "%c" , contentlenOff);
//fprintf( stdprn , "%c" , boldOff );
else
/* else print it in normal mode */

fflush(stdprn);

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.

Call an executable program inside function module and pass the table values
Hi,
i'm pretty new to HR Abap programming. I have a requirement like "calling an executable program within a function module and the output of the program data(Stored in internal tables) should be passed to the function module tables".
I've some idea about SUBMIT keyword and i used it in the function module..
Please do the needful to solve this.
Regards,
Selvi.Hi,
Thanks for all your reply.
I've used Option 3 as per dsouzajovito suggestion. Now i'm getting data in function module tables using import/ export table to memory concept.
Again a small issue arises, while i'm executing function module it fetches all pernr available in the server and displays the details of last pernr. GET pernr statement is used in the Z report and submit statement is used like this as follows.
SUBMIT ZHR_RFC_PAYSLIP WITH PERNR-PERNR EQ EMPCODE
WITH PYBEGDA EQ FDATE
WITH PYENDDA EQ LDATE
AND RETURN.
Pls suggest if there is any corrections in the code.
If i give a pernr as input in the function module, then it should fetch the details related only to that pernr.
FYI, No selection screen is used here as per requirement.
Regards,
Selvi. -

Calling native functions from java w/out DLL
If I invoke a JVM inside my c++ app and try to start up a class that calls a native function, do I still need a DLL for that? Or will it look to my header file and then look to my implementation somewhere in a c++ class?
For example:
WinMain() - Invokes JVM and loads "HelloWorld" java class, then calls its 'main' method.
HelloWorld.java - 'main' method calls "displayHello();" a native function.
HelloWorld.h - defines displayHello native interface
So it looks simply to the cpp implementation of the interface...I tried executing this but it isnt working...is it even possible?OK, I attempted what you posted by writing the following code... please look at because I get a 'main' not found error. I am trying to execute this from a win32 app...

Preloading and initialization of function calls brings response to a halt
I am creating a form with many CFC calls to the server.
However, on initial load, I am calling all these functions so that
my detailregion which relies on the result set from these
function calls would not error out. These initial functions do not
return any results - there exist to satify the regiondetail
bindings.
Eg. my initialization calls
var getEmployees = new Spry.Data.XMLDataSet(someCFCFile,
"employees/employee_id", { useCache: false });
var getDocs = new Spry.Data.XMLDataSet(someCFCFile,
"employees/employee_id", { useCache: false });
My issue is that the number of calls I am making are causing
the page to take 15+ seconds to load. I can't do without them
because my regiondetail rely on them initially. And also, later on,
my code uses these variables to make other calls Eg.
getEmployees .setURL(someCFCFile);
I have tried to perform these initial call with a null value,
but IE is still taking just as long to process these calls.
Eg.
var getEmployees = new Spry.Data.XMLDataSet(NULL,
"employees/employee_id", { useCache: false });
Please help. Thanks.Either Restrict Access or a Send Email Instance. Once I have tried to add either one of these to a page or successfully added, then I can't use ADDT at all.
For instance I click on any of the Wizards to run them, I get a ADDT window with the word loading across it. It sits and spins.
I have spent all afternoon trying to just get back to where I can work with ADDT again normally. The only way I have found that ADDT will work again after trying to utilize the email function or the Login function is to delete all of the ADDT include files and re-install.
Not very time affective.
