Problem with JNI form C++

Hi all,
I'm fairly new to programming with JNI, so please excuse me if I ask a dumb question.
I'm trying to call a Java method from a C++ class, but when I run the program, it throws an error, crashing the program. I'm pretty sure the problem is that the call to env->getMethodID() is throwing an error. I have looked around to try and find a way call a function with no arguments, but all of the examples that I have found all call a Java main.
I'll post my code and the error message below so that things are a bit clearer.
Thanks,
Robert.
Here is the main.cpp. This is where the program is started.
#include "/usr/lib/jvm/java-6-sun-1.6.0.06/include/jni.h"
int main()
   JNIEnv *env;
   JavaVM *jvm;
   jint res;
   jclass cls;
   jmethodID mid;
   // creation of the JVM
   JavaVMInitArgs vm_args;
   JavaVMOption options[1];
   options[0].optionString = "-Djava.class.path= .";
   vm_args.version = 0x00010002;
   vm_args.options = options;
   vm_args.nOptions = 1;
   vm_args.ignoreUnrecognized = JNI_TRUE;
   res = JNI_CreateJavaVM(&jvm, (void**)&env, &vm_args);
   // now the rest of the code can work
   cls = env->FindClass("Test");
   mid = env->GetMethodID(cls, "run", "()V");
   env->CallVoidMethod(cls, mid);
   jvm->DestroyJavaVM();
}Here is Test.java
public class Test
   public void run()
      System.out.println("stuff");
      foo();
   public void foo()
      System.out.println("asdfasdf");
}And here is the error message.

Yeah, so I just figured out what was wrong. I wasn't calling main from in Java. My bad guys.

Session problem with a form that calls psp web page.

Hi,
My unique form is based on table A.
Within the form I call a stored procedure, which insert data from A into tables B,C,D
And then within the same form I call a psp procedure using web.show_document('http://server:8080/plsql/psp_procedure?pvId=1001);
The plsql web page displays data from tables B,C,D for each single pvId.
The problem is:
If any commit is issued the psp web page contains no data from B,C,D.
I suppose I'm working with two different sessions, can I work within the same one?
Thanks

Hi,
I'd say the main problem is that you have both rows with the same name 'Rangée1'. This is not a good idea, especially as the first row is the repeatable row.
When objects have the same name, you can see the instances in the hierarchy, eg 'Rangée1[0]' and 'Rangée1[1]'. The instances use a zreo-based numbering system.
By the way you can also see it in the Object > Binding tab:
So that is when you have multiple objects with the same name.
The problem with your form is that when objects are repeated (add new instance button), then these new objects also have instances, eg 'Rangée1[0]', 'Rangée1[1]', 'Rangée1[2]', etc.
So the Acrobat gets confused ;-)
I have renamed the second row 'Rangée2'. That seems to have solved the problem.
Here is the form back to you: https://acrobat.com/#d=jcCs7X85xeRYQjvI2Yb*Cw
Good luck,
Niall

Problem with HR Forms

Hi,
I am having problem with HR Forms. I am trying to edit renumeration statement form (Copy of the standard form, with custom infotype fileds).
One of the Single Fields was spelled wrongly, and I am trying to correct it. I went to the chnage screen, double clicked on the faulty field, changed its name, and pressed 'Transfer'. It asked for a customizing request, and saved it.
If I again go to PE51, and check the form, the changes I made are not reflecting. Why is this? can anybody help?
The field I require is P9001-ZCREWNO. But it takes only P9001-zcrew. Is there any limit of 5 characters on length of filed name? (All other changes are reflecting, only this particular change is not reflecting.)
Thanks
Krishna

Sameer,
Thanks for the reply. That is already done. I already have the field available in the F4 help of the 'Single Field.
The field name is ZCREWNO. But when I give this and save it, it says 'Saved'. But if I open again, the stored field name is actually ZCREW (That is only 5 characters). Because of this, the filed value is not getting populated.
In Pe51_checktab, filed name is ZCREWNO.
Thanks
Krishna

Problem with multiple forms and subview

I have a problem when using NetBean Web Pack (JDK6, Net Beans 5.5, JSF 1.2).
1) I created a JSF page (hello.jsp) and a page fragment (header.jspf) inside Web Pack, and let the JSF page (hello.jsp) includes the page fragment.
2) The include instruction is outside of the "form" element id=main_form() of the first JSF page.
3) Inside the page fragment (header.jspf), I put a form (id=header_form) with some input fields inside the "subview" element.
4) When running the web application, the form and its children (id=header_form) inside the subview are not rendered.
It seems to be a problem with multiple forms on a page and the subview.
Do I use these JSF components incorrectly? Any advice?
Thanks

The forms are not nested.
hello.jsp
<webuijsf:body ...>

<div style="margin: 0px 0px 10px 0px; left: 0px; top: 0px">
<jsp:directive.include file="Header.jspf"/>
</div>

<webuijsf:form ...>
From above fragment, you can see the header.jspf is outside of the form element.

Awkward problems with JNI on J2SE 5.0

I'm experiencing a strange problem with JNI and I hope someone can help me out.I've installed Cygwin, MinGW and then the CDT plug-in for Eclipse C/C++ development. This means I've used the MinGW make utility. It successfully creates the DLL file, but for some awkward reason, function www_tutorial_jni_HelloWorld_displayHelloWorld cannot be found (UnsatisfiedLinkError: displayHelloWorld).
The Java class looks like this:
package www.tutorial.jni;
public class HelloWorld {
    public native void displayHelloWorld();
    static {
        System.loadLibrary("hello");
    public static final void main(String[] args) {
         try {
              HelloWorld hw = new HelloWorld();
              hw.displayHelloWorld();
         } catch (Exception e) {
              System.out.println(e.toString());
}The header that was generated by javah.exe (version 1.5.0_01) looks like this:
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class www_tutorial_jni_HelloWorld */
#ifndef _Included_www_tutorial_jni_HelloWorld
#define _Included_www_tutorial_jni_HelloWorld
#ifdef __cplusplus
extern "C" {
#endif
* Class:     www_tutorial_jni_HelloWorld
* Method:    displayHelloWorld
* Signature: ()V
JNIEXPORT void JNICALL
Java_www_tutorial_jni_HelloWorld_displayHelloWorld
(JNIEnv *, jobject);
#ifdef __cplusplus
#endif
#endifThe C++ implementation looks like this:
#include <jni.h>
#include "www_tutorial_jni_HelloWorld.h"
#include <stdio.h>
JNIEXPORT void JNICALL
Java_www_tutorial_jni_HelloWorld_displayHelloWorld(JNIEnv
*env, jobject obj)
    printf("Hello world!\n");
    return;
}I've made sure that the fully qualified name of the implementation function is identical to the one in the header. I don't understand why I still get the error; especially since checking the DLL reveals that a function called "Java_www_tutorial_jni_HelloWorld_displayHelloWorld" exists.
Could someone try and produce a successfull DLL/SO from the C++ code and then try and run the Java part on a 5.0 version of Java? I'm really curious as to what on Earth is going on...

... Otherwise, I would have
to add whatever directory I put my DLL into to the
PATH variable.Not necessarily. I believe the "PATH" also implicitly includes the "current directory". I also think that most JNI users put their DLL in a directory from which they also launch java (so it's in the current directory).
>
... a java.library.path set.
If I don't explicitly set a Java library path,
Eclipse can't even find the DLL. I'm beginning to
believe that Eclipse somehow screws up running Java
programs with native code...I don't know about that... Probably just something extra you have to do with your Eclipse project so that it can find the DLL.
But like I said, I don't really know - just trying to throw out ideas, small as they may be.

Problem with JNI and Parallel Port dll

Hi. I'm doing some testes with JNI. Firs i followed the netbeans tutorial for doing a C programa that prints somthing for java.. like.. "Hello java from C".
So i tried to load a dll from my dll. Like, I have this dll to use the parallel port on windows Xp. So i created a dll to access it an comunicates eoth java.
I did everything just fine.
When I start my Java app, the first thing it does is to load this parallel port dll and configure the functions of it.
After that .. I get this error
EXCEPTION_FLT_STACK_CHECK (0xc0000092) at pc=0x0093d269, pid=2284, tid=3000
Can someone explain why ?
(Sorry if i wasn't clear enough, english is not my native language, so ask if you don't understand something.. )

hi ,
I met the same problem this morning, and searched the www.google.com in order to solve it, as a result, your article was shown on my screen. :)
Till now I have read some technical information and solved my problems. Maybe the solution be useful to you:
==============================
error message : (Environment : Tomcat 5, Windows 2003, Mysql5)
2006-3-29 11:53:48 org.apache.catalina.core.StandardWrapper unload

==============================
cause: the number of connection to database exceeded.another word,too many connections.
==============================
solution: close the connection when it becomes useless for your program. :)

Hey All,
Has anyone ever experience a problem with maximizing or resizing their custom form? I have a rather large form that every time I try to maximize or resize causes Business One to hang and crash.
Any ideas what might be causing this?

Problem with JNI hello world

I found some tutorial on SUN site on how to use JNI. I'm using Eclipse to compije Java and C (via Cygwin) files. Here are complete files:
Hello.java:
class Hello
     public native void sayHello();
     static
          try
          System.loadLibrary("hello");
          catch(Exception e)
               System.out.println("exc");
     public static void main(String[] args)
          Hello h = new Hello();
          h.sayHello ();
}Hello.c:
#include <mingw/_mingw.h> //because there are some types needed for JNI
#include <jni.h>
#include "Hello.h"
#include <stdio.h>
JNIEXPORT void JNICALL Java_Hello_sayHello
(JNIEnv *env, jobject obj)
     printf("Hello world!\n");
     return;
}Makefile:
hello.dll : Hello.o Hello.def
     gcc -g -shared -Wl,--kill-at -o hello.dll Hello.o hello.def
Hello.o : Hello.c Hello.h
     gcc -c -g -I"$(JAVA_HOME)\include" -I"$(JAVA_HOME)\include\win32" Hello.c -o Hello.o
Hello.h : Hello.class
     javah -jni Hello
clean :
     rm Hello.h
     rm Hello.o
     rm hello.dllHello.def
EXPORTS
Java_Hello_sayHelloEverything goes well, but when I run java program it does nothin (it should print message, but it just exit without any error).I'm sure that it's something stupid, but I cant see what. Can anyone tell me what am I doing wrong?
Thenks.

Answer 1: yes, there was no problem. I compiled and started simple 'hello world' program from Cygwin and from WinXP console, and it worked well.
Answer 2: This is weird, I changed code to this:
Hello.java:
     public native int getInt();
          System.out.println("Returned int is " + h.getInt());Hello.c:
JNIEXPORT jint JNICALL Java_Hello_getInt
(JNIEnv *env, jobject obj)
     return 25;
}It does not print anything. I started this program from Cygwin and from WinXP console, and from Eclipse. Only if I debug in Eclipse (step by step) I get:
Returned int is 25and still I don't get Hello string printed (even if I go step by step). It looks like cygwin has some problem with OS. Do you have any idea what to do, I'm a bit confused?
Thank you.

Problem with JNI for target armlinux

Dear friends,
We have compiled CVM for ARM Linux and it is working fine for java programs as well as C programs.
But when I try to make shared library out of a sample hello world JNI program for arm linux it says 'jni.h: No such file or directory' and after that many lines 'syntax error' and 'parse error' etc.
But the same program is running fine on x86 linux. Problem only while cross compiling for arm linux. It is not problem with arm-v5t-le-gcc because that is working fine. Problem is with what I need to include in makefiles.
As I am new to this domain could anyone help me where I am missing?
Regards
Kishore

I'm not exactly sure what you're talking about, but it sounds like you may need to look into global references. Look at NewGlobalRef() and DeleteGlobalRef() and see if those help you out.

Problem with JNI

i have to implement a few standard APIs. As a part of the implementation I have to provide references to an object I create. Now my underlying code is C++ with JNI used to throw the Java APIs. Problem is JNI now returns different references for the same object and hence my prupose id defeated. Could anyone suggest how this problem can be overcome.

I tried to figure out what your problem is, but can't. Please rephrase it and give a bit more detail on what you are doing and what is going wrong.

Problem with Migration Forms to Apex ...

Hello !!
I discovered Apex a few days ago, so I began with the Oracle tutorials, where I found the conversion from Forms to Apex : "Converting Your Oracle Forms Applications to Application Express 3.2".
I tried to do the same, with a Unix server and my laptop with Windows.
I downloaded the Forms which where on my Unix server on my laptop, and then converted them with frmf2xml.bat.
Then I created a project and uploaded only one Forms Module (_fmb.XML). After upload, the Percent Complete column is lower than 100%.
My problem is at the following step : "Generating Your Application Express Application".
When I click on "Create Application", select "Based on Migration Project" and then on "Next", I have one of the following errors :
- 1 error has occurred * The project, "Test Gestuser" does not contain any Blocks associated with database objects.
- 1 error has occurred * Database schema PROCIE does not contain the associated database objects for the project, login. Ensure the database schema associated with the project contains the database objects associated with the uploaded Forms Module .XML file(s)
I really don't understand these two errors, having yet checked all the possible error sources, user, schema, ... ?:|
I have probably forgotten to give some informations, so ask them ;)
Thanks for your help,
Pierre C.
Edited by: Pierre C. on 19 juin 2009 17:22

I found the problem(s) ... but now I have another one !!
The problems are with the Forms : I opened them with Forms Builder and created a new Block with the assistant. Then I compared this block with another "normal" block : they haven't the same properties.
My block has an associated canvas and database source, whereas the other "normal" blocks haven't.
Where does the error come from ??
Is there something to do with Forms Builder ?
On my Unix server before downloading the forms ?
Another thing to do ??
Thanks,
Pierre C.

Problem with contact form

Hi-
I found a contact form for my Flash website but it's not working properly. It uses ActionScript 3 and PHP, both of which I don't know much about. Because of this, I can't pinpoint the problem or how to fix it. Here's what's going on:
1) Each field in the form only allows 3 characters and no special characters such as @ _ ! . , etc...
2) When the user goes to the next field in the form, the previous field appears blank but the when clicking on that again, the original text appears.
3) When submitting the form, it just keeps saying "in progress" and never shows the confirmation text nor does the email get sent. There is an HTML file included with this form but I am not sure if I need to put that in as I have embedded this form into an SWF file so I don't think I need that code but please let me know if I am wrong about this.
I am posting both the AS code and PHP code below.. if someone can help me figure this out I would greatly appreciate it. I am not sure which file the problem is in. If someone here doesn't know PHP then at least see the AS code and let me know if the problem is in that or not. That way I can pinpoint which file the problem is coming from and then seek further help if needed. To see the form in action, go here: http://www.poojasdesigns.com/ and click on "Contact Me".. here are the codes:

You say you don't know much about AS3, and that you have embedded this form into an swf. In what manner did you embed it, and what version of AS does the swf use? Have you tried using the form in the page that was provided as a standalone test to see if it works?

Problem with a Form field, need help

I work for a small police agency and I am our IT guy. Most of my IT tasks have many been hardware and system software and networking. I have been trying to learn and teach myself programming. I also create forms for agency use. I have been working on a form and want to add increased functionality to allow our officers to issue a citation with the least amount of time spend on the form. One main issue is that we have to have a unique citation number. We have come up with a format that will specify as such: YYYY(Officer's 4 Digit ID Number)-(Auto Incrementing number). So, for instance, if this is my 55th citation issued and my ID number is 0100 the citation number would appear like this: 20120100-0055. The ID number will be entered by the officer earlier in the form. The problem I can't seem to vision around is how I will keep the number to increase by one and have it maintain that way. I want it to be form specific, because each officer has their own vehicle and MDT that the PDF will reside on at this time.
So far, what I have toyed with in the past 30 minutes is this:
var Ticker = 0001;
var Year = getFullYear();
var x = getField('OfcIDNo').value;
Eventually the form will be autocreated by a program that will be run from a centralized server. I have even thought about running the from from a server and taking all the data and INSERTing it into a SQL Server 2008 Express DB table on a server, but I'd still have to have the citation number created at the form as the officer fills in the data. The last four of the number doesn't have to reset when the year changes, but it would be a plus. Any information anyone can help with I would appreciate it.
Thanks in advance

Seems like it was too easy, is it safe to assume that javascript and javascript functioning in Adobe PDF is a bit different learning curve? That does help, the only thing that I'm missing is the Auto Incrementing 4 digit number. I was toying with assigning a variable in the globals that would auto increment but having problems with how I would execute it. Each copy of the form would be installed on each officers MDT so the number would be specific to that officer. The format will be YYYY"OFCIDNo"-####. I would like to assign the number to the global variable on the execution of the Print Dialog. This way the officer an clear the form if he/she needs to start over and then it stays whether or not they close the file and reopen it.
That syntax has been very helpful to get started.
Thank you,
David

Sounds like a problem with the privileges.
Try creating a new user, say user_temp, and grant the user Manage privilege to All Portal DB Providers and Manage to All Schemas.
Try creating a form after logging in as user_temp.
The minimum privileges required to create a Portal DB provider component is Create privilege on the Portal DB Providers and Manage on the Portal DB Provider schema.
