How to Call C++ Method from Java

I need to call C++ method from Java.
I have gone through the JNI tuorial , but was not able to pin point things.
I read that :
You have to write JNI c functions which then call your C++ member functions.You need to write a JNI function which will call new on your C++ class.
Now i have java class :
Java Code JavaClass.java ---->
class JavaClass{
public native void nativeMethod();
    static
        System.loadLibrary("NativeCppCode");
     private void callCppMethod()
          //call C++ method
                JavaClass jvc = new JavaClass();
                jvc.nativeMethod()
}Cpp Code:
NativeCppCode.h---->
class NativeCppCode
public:
    getValue();
    setValue();
private:
   int a;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj);NativeCppCode.C---->
NativeCppCode::getValue()
   return a;
NativeCppCode::setValue()
   a = 1;
JNIEXPORT void JNICALL Java_JavaClass_nativeMethod(JNIEnv *env
               ,jobject obj)
NativeCppCode* nativeInstabce = new NativeCppCode();
NativeCppCode.setValue();
}Is this the correct way to do it.
Any suggestion would be a great help to me

tryit wrote:
I need to call C++ method from Java.Not possible.
JNI uses C methods.
Is this the correct way to do it.Same way you would do it in any C/C++ method (not java)
       MyClass* p = ....
       p->doit();
Common idiom for the pointer in the above is to pass it back and forth to your java code as a java long. You cast it it and from your class pointer. Provide an explicit java method to free it when done. Besides providing the explicit method also implement a finalizer to free it as well (however that is a fail safe and should not be relied upon.)

Calling c code from java

hello everyone
I have question
I need to call c program from java
I don't have problem with application or exe file in c it is working but when I call it from java it doesn't work there is no error but it doesn't work because when I execute the c program the black screen must be appeared so that I can enter the input file and then it produces the output file but in java I cann't see the black screen so please can you tell me the problem
I have used the following code to call c from java:
String line;
               String output1 = "";
                     Process p = Runtime.getRuntime().exec("cpp.exe");
                     BufferedReader input = new BufferedReader
                           (new InputStreamReader(p.getInputStream()));
                     while ((line = input.readLine()) != null) {
                           output1 += (line + '\n');
                     input.close();

Hi,
Try this in your code
p.waitFor();It is for waiting of the process till the completion of the I/O.

How can we call WinAPI's from java... any idea... its urgent

Hi all,
I am facing a problem, I want to call Win API's form Java. any idea..
Any win API.. like GetUserNameA.... (it fetches current user logged in).
Its bit urgent guys... i have always counted on u guys...
Thx & Regards
@mit

I needed to do exactly this; use getUserNameEx, a couple of weeks back and I asked, then solved it myself and posted my code. A forum search should turn it up,
The only method, of course, is to use JNI and do the call from C.

Calling HRMS APIs from a DotNet plateform

Hello,
I am new on this forum and I have difficulty in beginning, i don't know if it's the right category to post my question.
I'm working in a project looking for a solution of revision of the self-service's interfaces of oracle e-business suite, indeed I need an example or a document which can help me for using the HRMS APIs of oracle e-business suite via a dotNet plateform or SharePoint application.
I have to work on a middelware allowing retreiving and persisting data from oracle e-business suite database using oracle HRMS APIs like hr_appraisals_api. So haw can i call these APIs from .NET application how can i use a .NET code to call these api's ?
Can you help me please ? i'm waiting for your answers if possible and this is my e-mail address if necessary "[email protected]" .
I would be so grateful if someone can help me. Thank you in advance.
Cordially.

HRMS PLSQL API can be called from Java and .Dot net support to execute Java API . This way it could be done.

How to call OIM API from external app?

Hi,
I have an java application and I would like to call OIM API to accept a request. The application resides in separate server than OIM.
My questions:
*1.* What to do to call OIM API from external application (import any OIM jars etc.)?
*2.* Which method to use, setRequestResponse , closeRequest or any other?
I appreciate any help, thanks.
Edited by: m.m. on Feb 2, 2010 5:33 AM

Hello,
If it is an external client, you need to provide the "login" and "password" details explicitly in the code (something like this), before getting any other Interface control to invoke the OIM APIs -
public class OIMAPIClientTest {
public static void main(String[] args) {
try{
System.out.println("Starting...");
ConfigurationClient.ComplexSetting config = ConfigurationClient.getComplexSettingByPath("Discovery.CoreServer");
Hashtable env = config.getAllSettings();
tcUtilityFactory ioUtilityFactory = new tcUtilityFactory(env,"xelsysadm","abcd1234");
System.out.println("Getting utility interfaces...");

Curious thing while calling a procedure from Java !...

Hi !. My name is Agustin and my doubt would be the following one... I am working for a e-business comp and they asked me to call a procedure from java... The code is the following one:
CallableStatement cs = null;
System.out.println("Fecha Nro. 1: " + paramFechaDesde);
System.out.println("Fecha Nro. 2: " + paramFechaHasta);
try
cs = getDBTransaction().createCallableStatement("{call paq_w_ListadoSiniestralidadART. p_sinsiniest(?,?,?,?) }",0);
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setInt(1,paramContrato.intValue());
cs.setString(2,paramFechaDesde);
cs.setString(3,paramFechaHasta);
cs.setString(4,paramNombreArchivo);
cs.executeQuery();
String nomArchivo = cs.getString(4);
System.out.println("### " + nomArchivo +" ###");
catch(SQLException e)
The weird thing is that, I was expecting a big big exception but the only thing I got is
### Error ###
The String I am expecting is a file's name !; so I am a little bit confused...
Also I didn't know where to post so If it's in the wrong category... I apologize !... If anyone need more details, I'll be checking out... The account I am working on is an Insurance company, who is the one who provide access to the DB and the procedures... So I can't check what's inside...

Please provide your Java and OS versions, the JDBC jar file and the Oracle DB version being used when you post.
>
I was expecting a big big exception
>
Then why do you have an empty exception block? That just makes it disappear so you won't see one if it happens.
And your code has
cs.registerOutParameter(4,OracleTypes.VARCHAR);
cs.setString(4,paramNombreArchivo);You use 'registerOutParameter' for an OUT parameter and the 'setXXX' methods for other parameters.
Remove the 'setSTring' for the OUT parameter.
Then as malcollmmc already said
>
Sounds like the PL/SQL is returning "Error" as the 4th parameter of the call
>
The actual value returned by PL/SQL is strictly determined by the PL/SQL code and Java and JDBC are not involved.
Fix the code problems, retest, and folllowup with whoever wrote the code if it still returns ERROR.

Call .bat file from java code

Calling a servlet from java

How to call a servlet from java?
your help is greatly appreciated..

Welcome to the forum
You seem to be misunderstanding something. Do some googling to learn what you need about servlets. Simplified, servlets are java code that's hosted by a web container, such as Tomcat. When a servlet gets called as a consequence of someone requesting a url from the container, it takes in a request object and a response object. All the magic is then in creating an appropriate response (e.g. html) for the incoming request.

I think you need to find out which Windows DLL implements the function and

I'm afraid we have to make it work for NT, 95 and probably 98 too, so we're
looking for something a bit more robust than the environment variable.

How to use d2kwutil for calling win-api programs in form 6i

I WANT TO USE d2kwutil for calling win-api programs in form 6i.
PLEASE GIVE ME IT'S SOLUTION.

D2kwutil comes with a Demo Form WAPIDEMO - you can run this to see every function demonstrated. You can even run a function using the demo form and copy the syntax required directly into your own form -------------------------
yes in have got that WAPIDEMO from web and run successfully but
i can not do those codes in my owdn form.Because i do not get those apis like
win_app_session in form 6i.
Again i could not understand how that form runs without connecting to database.
Please describe the solution.

How to call gnuplot command from java

Hi there,
In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
Thanks a lot for any suggestions!
Jack

Hi, there:
Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
Thanks,
Jack
P.S. Would you guys answer my question after I use up my duke dollars? :- )

How to call remote API from root SharePoint 2013 domain (not an app)

I'm trying to follow the article
http://msdn.microsoft.com/en-us/library/office/fp179895%28v=office.15%29.aspx
For a SharePoint 2013 hosted under O365, do I need to create an app to use the SP.* methods in sp.js? I need to call a remote API from the root domain (https://mycompany.sharepoint.com). But the app, as mentioned in the article
above, deploys on a whole different URL (https://mycompany-a2d3f4t454.sharepoint.com).
I need to be able to call the API from pages like https://mycompany.sharepoint.com/pages/default.aspx. Is this not possible?

Hi,
According to your description, my understanding is that you want to call remote API from the root domain site.
Yes, you can use SharePoint hosted app to achieve it. SharePoint hosted app has app web and host web, you can create an app to call the remote api in the host web from app web.
Here are some detailed articles for your reference:
