After reading a lot of articles, tutorials, and overviews about JNI (Java Native Interface)
I found that these steps
1.     Develop the Java code
2.     Compile the Java code to a class file
3.     Generate the header file
4.     Implement the native method
5.     Create the shared library or DLL
6.     Run the Java program
Is the common steps in JNI development
The most powerful link was
http://java.sun.com/docs/books/jni/html/start.html
and
http://www.netbeans.org/kb/55/beginning-jni-part2.html
and the pdf oh this link
http://www.ibm.com/developerworks/edu/j-dw-javajni-i.html requiring IBM registration to download it.
But I have already the DLL, and want to the stright forward way to use its functions by java code only.
I don not to write any C++ code .
Is this possible???????????????????????????????

Can we call a method in stateless session bean ?

Can we call a method in stateless session bean in onMessage method?

Hi,
The purpose of service locator is to abstract the lookup of the server side services like ejb and DSNs. It should be a normal java class but as such there is no such restriction. You can have a look at the service locator patter at the j2ee blue prints.

How can we call the method of used controller?

Hi All,
   i created two WDA Applications.( like YWDA1,YWDA2 ) . i am using the component WDA2 in WDA 1.and displaying the one view of WDA2 as popup window in WDA1 on action of one of the input element in the view of WDA1 by using the method l_window_manager->create_window_for_cmp_usage
I have a button on the view of WDA2 which has appear in the popup window...how can i call the method which has binded to that button....and where should i code that...and i need to assign selected value in the popup window to input elemetn of view WDA1
Please help me to resolve this....
Regards,
Ravi

You can not directly call view's event handler from other component.
create a method in component controller of the second component and in the button click call the component controller method. ( also make the method as interface so that you can call it from other components )
Now, you can call the interfacecontroller's method
DATA: l_ref_INTERFACECONTROLLER TYPE REF TO ZIWCI__VSTX_REBATE_REQ_WD .
l_ref_INTERFACECONTROLLER =   wd_This->wd_CpIfc_<comp usage name>( ).
l_ref_INTERFACECONTROLLER->Save_Rr(
    STATUS = '01'                       " Zvstxrrstatus
save_rr is the method of second component controller

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

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.)

Can I call an interface from java

Dear All,
Can I call an interface from java in ODI ?
Best Regards
Arc

Short answer, Yes.
Long answer - you must create a scenario from the interface (the scenario is the "executable" code), right-mouse-button on the interface in the tree and "Generate Scenario". This can then be called using the invocation api this is documented in your <installationdirectry>/oracledi/doc/sdk/invocation. This points you at all the necessary classes etc to use.

Call DLL function from JAVA

Could you help with an example?

Help: Calling C++ method in Java source code?

I found a method very useful, but it is written in C++, really hate to translate it into Java. My questions are:
1. Is it possible to call it in my java source code?
2. If so, how to call the C++ method in my Java program?

To answer your first question, yes it is possible to call your C++ method from Java. There are several answers to your second question, however. You can use the raw procedural JNI and code your own layer that maps your Java proxy object instances to C++ peer instances. Another option is to generate the code for that mapping automatically. How? Download JNI++ (http://jnipp.sf.net or http://www.sf.net/projects/jnipp). JNI++ is a free, open-source toolkit that makes easy work of bi-directional Java <---> C++ integration -- it will even generate your makefile. Comes complete with a 100-page printable PDF User Guide and plenty of examples to get you started.
Good luck with your project.
