Calling a native function from a dll

Hi all,
I want to call an api function exported from a dll using java. For example l like to call a function from kernel.dll (Windows). How can i do this. Do i have to create another dll for this?

hi,
you need to use JNI
you have to create de DLL , and call kernel32.dll in.
like that:
java_class.class ==> first_dll.dll ==> kernel32.dll

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...

private void callback(int depth) {

      nativeMethod(depth + 1);
      System.out.println("In Java, depth = " + depth + ", back from C");
    } else
      System.out.println("In Java, depth = " + depth + ", limit exceeded");

Calling a function from a DLL, exectution in background mode.

Dear Experts,
We have created an ABAP report the calls a function from a DLL file. If the report is executed in on-line mode the program calls and executes the function from the DLL, but if the ABAP programa is executed in background mode it doesnt calls the DLL function.
Do you know a way to solve the problem when executing in background mode?
Best regards.
Antonio

Hi Gabriel,
Let me explain in details about my DLL function.
We are importing the business partners from legacy system into the SAP CRM system, so at the moment we created the BP master data via BAPI, I get the name of the BP and this moment I call the function in the DLL file. I export the parameter name and I receive back a simplified string with the name reduced to a code. This code I get back from the dll it is insert in a Z table, so there is no interaction in the screen, all must be executed in background mode, because there are a lot of business partners to be converted in SAP system.
I am sending my code for your considerations.

Can I call a function from a dll in LabVIEW that returns:double*string and int.?

I have a function from a dll that return a double* string and an integer. How can I call this function from LabVIEW? There is a possibility to work in LabVIEW with a double* string?

Two difficulties I can see with this.
First the application seems to allocate the array of references
internally and return a pointer to that array. In that case there must
be another function which then deallocates that array again.
Then you would need to setup the function call to have a pointer to an
int32 number for the deviceList parameter and another pointer to int32
one for the plItems parameter.
Then create another function in your DLL similar to this:
HRESULT WRAPIEnumExtractDevice(WRAPI_NDIS_DEVICE *lpDeviceList, long i,
CHAR lpszDeviceName, LONG lenDeviceName,
CHAR lpszDeviceDesc, LONG lenDeviceDesc)
if (!lpDeviceList)
return ERROR_INV_PARAMETER;
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceName, -1,
lpszDeviceName, lenDeviceName,
NULL, NULL);
if (lpDeviceList[i].pDeviceName)
WideCharToMultiByte(CP_ACP, 0,
pDeviceList[i].pDeviceDescription, -1,
lpszDeviceDesc, lenDeviceDesc,
NULL, NULL);
return NO_ERROR;
Pass the int32 you got from the first parameter of the previous call as
a simple int32 passed by value to this function (and make sure you don't
call this function with a higher index than (plItems - 1) returned from
the first function.

Call multiple functions from same dll with call library function

hi,
i am working on a project in wich we need to make a UI to read out a sensor network.
the UI should be usable in any project, but every node needs a different piece of code depending on the type of sensor with wich it is equipt.
so i need to be able to call different pieces of code when i need them, and still be able to use the UI in future projects with possibly new types of node we now don't have.
so someone told me to use DLL's, cause then i would be able to call the code i need the moment i need it.
but i have never worked with DLL's (just learned about this option 3 day's ago) so i have a question.
i know i can dynamicly change the DLL i call with the call library function, but can i dynamicly change the function i call from that DLL ?
or do i have to put a new call library function for each function i want to call, even if its from the same DLL ?
kind regards,
stijn

Thepath on the Call Library Node can be used to load a different DLL. Obviously since you can't change the function name your other DLL would have to export exactly the same function name and of course with the same parameters. This is seldom the case so it is not the main use of the path input to the Call Library Node. It's main use is as indicated to load DLLs at runtime rather than at load time of a VI. So that an application can run even when the DLL is missing, until the moment the functionality from that DLL is needed.
If you can make sure that all your DLLs export the same function name with the same parameter you can use the Call Library Node to call into different DLLs through the path input. If however you would need to call different function names you would have to resolve to some DLL which does do the dispatching and invocation using LoadLibrary() and GetProcAddress(). But unless you need to go with DLLs for some reason using the Call By Reference Node can give you an even more flexible approach.

Calling a function from a dll written by using visual studio c++

Hi, how can i call a function from a dll which is written by visual studio c++ in test stand? Although the functions in dll are exported and i've chosen c/c++ adapter, i saw no function in test stand. Is there a different step while i'm calling a function from a dll written by c++ than calling a function from a dll written by cvi?

Hey Sadik,
Selecting the C/C++ DLL Adapter Module should be sufficient for this. When you drag an action step for this onto the Main Step and navigate to the location of the DLL, the function list should populate and you should be able to select the function you want to use. If this is not the case, would you be able to post this DLL so that we can test this on our end?

Calling a native library from Java

Hello,
I'm trying to call a native method (windows dll) from a web service implemented in Java. I've confirmed that the class I've created to call the native method works when used outside of my web service (ie. in a standard Java application). However, when I try to use the class in the web service, an exception is thrown when
System.loadLibrary("MyLibrary");
is executed. The exception thrown is:
InvocationTargetException
JAXRPCSERVLET28: Missing port information
Does any one have any suggestions as to what might be causing this error?
Thanks

There are basically 3 steps to calling a native method from your Java code.
1. Create a C/C++ stub function that will translate between your Java call and the native C method.
2. Create the dll that exports the stub function.
3. Invoke the System.loadLibrary("myDllName") method.
Here's what I did to learn how to use the JNI.
I first created the class that would be calling the dll:
public class CallDll
/** Creates a new instance of CallDll */
public CallDll()
static
//LVtoJava is my dll name.
System.loadLibrary("LVtoJava");
//AddDll is the name of the function I'm exporting from my Dll
//It does not have to be static
public native static double AddDll(int func, double x, double y);
I then used the javah utility in the jdk/bin directory to create the C stub header file. Once you have the generated stub header file, you can create an implementation file, and compile it into a dll.
//My C++ stub, generated by javah utility
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class LabViewDll_CallDll */
#ifndef IncludedLabViewDll_CallDll
#define IncludedLabViewDll_CallDll
#ifdef __cplusplus
extern "C" {
#endif
* Class: LabViewDll_CallDll
* Method: AddDll
* Signature: (IDD)D
JNIEXPORT jdouble JNICALL Java_LabViewDll_CallDll_AddDll
(JNIEnv *, jclass, jint, jdouble, jdouble);
#ifdef __cplusplus
#endif
#endif
You may want to note the stub function's signature and how it decorates the function name that you created from your Java class. Do not modify it, as the format is required by the JNI. The javah utility appends the fully qualified package name and the word Java, separated by underscores, to your original function name. You do not need to change the name in your Java class.
All the other special key words in the function's signature are defined in the jni.h or the jni_md.h (if your using windows).
You may want to refer to the JNI documention on Sun's website. The book I learned out of is the Core Java Volume 2, published by Sun Microsystems Press. It goes through the details of invoking your first native function and I've found it to be a good reference.
Hope this helps,
PS. I seemed to have found the issue with calling my dll from a web service. My dll is actually calling another dll and that seems to be the source of my problems. When I removed the call to the 2nd dll, everything worked fine. So now I need to figure out why the 2nd dll call is an issue.
Any suggestions?

Can I call a C function from Java (using JNI) ??

hello,
I need to call one C function from remote device and get its return value(o/p) (for my application it is device SSID ) and display in the client PC.
Is it possible in java without using SNMP connction?.
please give me idea about it.
I need this information as soon as possible.
Thank you.

see JNI...
basically declare a native method in your java class, then run javah on the class thus generating a *.h file. Then implement the c/c++ function. Compile the c/c++ part as a shared library, and make sure its accessible from your LD_LIBRARY_PATH env variable.
Go through the steps in the JNI docs, and things shoulde be fine... hopefully ;)

Using PostLVUserEvent function from Labview.dll

I am trying to use the PostLVuserEvent function from the labview.dll and corresponding extcode.h file. I have made my own dll using CVI that uses this function. I then use Labview to call my dll. My dll compiles fine. No issues, no errors. LabView can call my dll function containing the PostLVUserEvent function with no errors. However, the event number LabView passes my dll is not the same event number I receive so no LabView event is triggered.
Has anyone had this issue?
We are trying to solve it from the LabView side and the CVI side but cannot seem to get it to work. The examplesI have found here were compiled using C++ and those seem to work. I do not know why when I compile my program in C, it creates the dll but does not work. If I had to guess, i think it's an issue with pointers vs non-pointers. When the LAbview program selects my function from the dll, it shows the argument PostLVUserEvent as a pointer when in my dll, it is not a pointer PostLVUserEvent....
Any ideas?
Thanks in advance.

Hello Blue
Take a look to this one, it was created on C, I think the .c and the .h files will give a good idea, how the function should be implemented. It is important when calling the dll on LabVIEW, to use the std calling convention and run it on the UI thread.

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :

How can I call a plsql function from an attribute?

I have an attribute defined in an element. I want execute a PLSQL function from the attribute, and display the returne value with an HTML template.
I've defined the attribute's type like PLSQL, and I've put the called of the function in the value of the attribute, but it doesn't work. The only value I obtain is an URL (I think that is the URL of the function or someting like this).
How can I call to my function from the attribute and display the returnes value in the page?
Thanks.

Thanks, but it doesn't work. I have an attribute called ID_BOL and I want to associate a sequence to that attribute. I've created a function, with the sequence. This function return de value of the sequence. I want taht the attribute takes the value of the sequenece dinamically.
I've tried it, creating the type attribute like PLSQL, and calling the function from the attribute, but it doesn't work.
How can I return the sequence value to my attribute?

Help needed in calling a javascript function from a jsp

Hey guys,
I need help.
In my jsp I have a field called date. When i get date field from the database, it is a concatination of date and time field, so I wrote a small javascript function to strip just the date part from this date and time value.
The javascript function is
function formatDate(fieldName)
          var timer=fieldName;
          timer = timer.substring(5,7)+"/"+timer.substring(8,10)+"/"+timer.substring(0,4);
          return timer;
Now I want to call this javascript function from the input tag in jsp where I am displaying the value of date. Check below
This is one way I tried to do:
<input size="13" name="startDate" maxLength="255" value=<script>formatDate("<%=startDate%>")</script> onChange="checkDate(this)">
I even tried this:
<input size="13" name="startDate" maxLength="255" value="'formatDate(<%=startDate%>)'" onChange="checkDate(this)">
But it dosen't work
Please help. I am struggling on this for days.
Thanks,

IP - Is it possible to call exit planning function from ABAP Report..

Hi All,
Greetings.
Is it possible to call exit planning function from ABAP Report (t-code SE38) ? Or I mean is not limited only to be called from ABAP Report, perhaps from BSP / Web-Dynpro / Function Module.
If somebody here has been doing it before, I'm keen to ask to kindly share it. Particularly how to call and transfer data to that exit function.
Or if somebody has done in BPS, appreciate if it can be shared too .
Thanks a lot and have a good day,
Best regards,
Daniel N.

Hi.
You can achive this as suggested by Mattias in your previous post.
Lets say you have next data structure:
CostCenter | Amount | PercentForDistibution |
Create input ready query in this format. Restrict cost center by variable type range.
Create WAD with analysis item.
When you run web page you enter range of cost centers (lets say you will enter 101004 to 101010).
I assume you have data only for 101004 in your cube (lets say 1000).
You will see only one record in your webpage.
CostCenter | Amount | PercentForDistibution |
101004       | 1000     | NOTHING
When you create WAD in analysis item properties set "NUMBER_OF_NEW_LINES" to lets say 1 (so in WAD you will see always one blank line for entering new data).
Just add 6 new records:
CostCenter | Amount   | PercentForDistibution |
101005       | NOTHING| 10
101006       | NOTHING| 30
101007       | NOTHING| 20
101008       | NOTHING| 25
101009       | NOTHING| 5
101010       | NOTHING| 10
Then run planning FOX function like this:
FOREACH Z_COST_CENTER.
IF {Amount, Z_COST_CENTER} <> 0
Z_AMNT_TO_DISTRIBUTE = {Amount, Z_COST_CENTER}.
ENDIF.
ENDFOR.
FOREACH Z_COST_CENTER.
IF {PercentForDistibution Z_COST_CENTER} <> 0.
{Amount, Z_COST_CENTER} = Z_AMNT_TO_DISTRIBUTE * {PercentForDistibution Z_COST_CENTER}.
ENDIF.
ENDFOR.
It is not perfect FOX, but as an idead, it should work.
Regards.
