Call function defined in other class

Hi..
I am new to Java programing .
I want to know how to call a function defined in second class from first class.
Please help me.

Hi..
If both the classes are in same package, and the function is not private, u can call the function by using an object of the second class. If they r in separate packages, u have to import the package in which the second class is. In any case, public methods are allowed and private methods are not allowed to be invoked.
Hope this info may help u..

How to call methods defined in another class ? is it possible?

Hi all,
I am new to using JNI, was wondering if this is possible and how I might be able to do this. I'm trying to call some set/get functions defined in a class that is not part of the class where I have my native code defined and called...
Let me explain a bit, I have a class JobElement (singular Job) that stores all the data associated with a Job, such as job name, job id, etc.
Another class JobsElement (plural Jobs) contains all the Jobs that are currently running.
The code is set up something like this...
class JobElement {
     String jobID;
     String jobName;
     public void setJobId(String newJobID) { jobID = newJobID; }
     public void setJobName(String newJobName) { jobName = newJobName; }
class JobsElement {
     Date timeDateStamp;
     JobElement job;
class AppRoot {
     JobsElement allJobs = null;
     JobElement _currentJob = null;
     public native getAllJobs();
}In my native method, getAllJobs(), I essentially want to call the set functions that are defined for JobElement when filling in the information of the Job. (then finally add the JobElement to the JobsElement list)
In summary, I basically want to know if it's possible to call the equivilent of this java code from the native code??
     _currentJob.setJobName(newJob)
In the native code I tried to find the setJobID method but got a NoSuchMethodError. (which is what I expected)
Thanks in advance.

Hi,
In your getAllJobs(), the JNI Equiv would be JNIEnv_ClassName_getAllJobs(JNIEnv** anEnv, jobject jAppRootobj)
Since you are calling the AppRoot object's method, the jobj in the native method call will be jAppRootobj-AppRoot's instance.
What you can do is
Get the field id of _currentJob.
Get the <jobject-value of currentJob> of JobElement i.e. currentJob.
Then get the method ids of setJobID and setJobName.
Call these non-static methods on <jobject-value of _currentJob> to set the values.
I hope I made a try to help you. Please correct me if I am wrong.

Simulation model which call functions in an other dll...

I have a C simulation model that I implement like NI Model Framework template (NI_VStand_Model_Framework_Guide.pdf ). If I use this simple model I can deploy on my PXI. But I must call functions which are in an other dll. When I call functions in other DLL I can't deploy because Veristand specify that the model is not compatible.
NI VeriStand: The specified compiled model is not compatible with NI VeriStand.
=========================
NI VeriStand: NI VeriStand Engine.lvlib:VeriStand Engine Wrapper (RT).vi >> NI VeriStand Engine.lvlib:VeriStand Engine.vi >> NI VeriStand Engine.lvlib:VeriStand Engine State Machine.vi >> Model Execution.lvlib:Initialize Model Loop Data.vi >> SIT Model API.lvlib:Initialize Model.vi >> SIT Model API.lvlib:Load Model DLL.vi

NI VeriStand: Failed to load c:\ni-rt\NIVeriStand\Models\LD1_T1.dll
If I use DLL Checker there is no bad import. How to add a simulation model in veristand which call function in an other DLL?

Thank you for your answer.
I know how to import a dll in veristand. My Dll is LD1_T1. I can import it in Veristand without error. But this DLL depends of an other dll (addition.dll) as you can see in the print screen.
When I try to deploy to my PXI I have an error message of compatibility.
NI VeriStand: The specified compiled model is not compatible with NI VeriStand.

NI VeriStand: Failed to load c:\ni-rt\NIVeriStand\Models\LD1_T1.dll
For LD1_T1.dll I have use NI Model Framework template (NI_VStand_Model_Framework_Guide.pdf ).
If I check my Dll with dll checker it's ok but I can't deploy.
Please somebody have an idee to deploy my model ?

How to call functions defined and packed in a .dll file

hi,
my client have provided me with a .dll file which implements all functions tasks.
earlier we created a applications in vb that accessed functions from the .dll file provided by client.
now he wants java implementation of the same application written in vb.
now how to access functions in .dll file provided by the client from java source code.
regards,
s.mohamed asif

For this you should write JNI wrappers for the native functions, that is you create class with the native function prototypes as native methods, implement these methods with native functions in JNI module, each JNI function calls a native function from your DLL.
I know that JNI coding is a greate pain. That is why I am developing Java Platform Invoke which is a paradigm of .NET Platform Invoke. See my demo at
http://www.sharewareplaza.com/Java-Platform-Invoke-API-Demo-version-download_49212.html

Calling functions of the inner class in .java code file

Hello,
I created a .java code file in Visual J#.Net and converted it into
the application by adding the "public static void main(String args[])"
function.
I have created the two classes one extends from Applet, and the other
extends from Frame. The class which I inherited from the Frame class becomes
the inner class of the class extended from the Applet. Now How do I
call the functions of the class extended from Frame class - MenuBarFrame
class. the outline code is
public class menu_show extends Applet
------init , paint action function---------
public class MenuBarFrame extends Frame
paint,action function for Menu
public static void main(String args[])
applet class instance is created
instance of frame is created
Menu , MenuBar, MenuItem instance is created
and all these objects added
I have Created MenuBarFrame class instance as
Object x= new menu_show().new MenuBarFrame
????? How to call the functions such as action of MenuBarFrame class - what
should be its parameters??????
}

Here's how I would do it:
interface Operation {
    public int op(int y);
class X {
    private int x;
    public X(int x) {
        this.x = x;
    private class Y implements Operation {
        public int op(int y) {
            return x+y;
    public Operation createOperation() {
        return new Y();
    public static void main(String[] args) {
        X app = new X(17);
        Operation f = app.createOperation();
        System.out.println(f.op(-11));
}Your code, however, has some serious "issues". You typically don't
instantiate an applet class -- that's the job of the applet viewer or Java plugin
your browser is using. If you instantiate the applet directly, you're going
to have to supply it an AppletStub. Do you really want to go that way?
Again, use an applet viewer or browser, or better yet, why write applets at all?

Calling function defined in one package

Hi,
I have a package ABC. In that I have a function xxx(param1,param2,param3)
I have a 2nd package XYZ. I need to use the above functionxxx in package XYZ and assign it to a vriable. How do i do it
Please guide me.
Thanks

shipment_to_siebel.get_prod_userkeys(r_stage_rec.material_number, r_stage_rec.sales_org, r_stage_rec.distribution_channel);Now show the definition of this code from shipment_to_siebel package body.
I guess you decided not to take the time to read the FAQ link posted to you.
Let me tell again
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.

Call function maximum print.

Hi all.
I have print proble. if sombody know that , please let me know.
if the number of itab is '400', when 300 times print is not printing. logic like below.
loop at itab.
call function 'OPEN_FORM'
    exporting
      device = 'PRINTER'
      dialog = ' '
      form    = 'Z_CPS_OUTBOX'
      options = option
    exceptions
      others = 9.
if sy-subrc <> 0.
    exit.
endif.
call function 'WRITE_FORM'
    exporting
      element = l_element
      function = 'SET'
      type     = 'BODY'
      window   = 'MAIN'
    exceptions
      others   = 8.
call function 'WRITE_FORM'
    exporting
      element = l_element
      function = 'SET'
      type     = 'BODY'
      window   = 'BARCODE'
    exceptions
      others   = 8.
call function 'CLOSE_FORM'
    exceptions
      others = 4.
if sy-subrc <> 0.
    exit.
endif.
endloop.

can u jot down ur exact requirement..
why r u opening and closing the form inside the loop?
u could have done this:
openform...
loop at itab.
writeform...
endloop.
closeform...

Best way to call a function in a generic class from a base class

Hi,
I have a generic class that works with subclasses of some other baseclass. When I construct the subclass, I call the constructor of the baseclass which I want to call a function in the generic class. e.g. suppose I have the following classes
public class List<T extends BaseClass>
    newTCreated(T t)
}

Sorry, I pressed Tab and Enter last time when typing the code so I posted without meaning to
Hi,

public class List<T extends BaseClass>
    public void newTCreated(T t)
        // add the t to some internal list
    public T getT(int index)
        // get the object from the internal list
public class BaseClass
    public BaseClass(List<?> list)
        list.newTCreated(this);
public class SubClass extends BaseClass
    public SubClass(List<SubCass> list)
        super(list);
}This doesn't compile because of the call to newTCreated in the BaseClass constructor because BaseClass is not necessarily of type T. Is there any way of checking when I call the newTCreated function that the BaseClass is actually of type SubClass? I could either add the call explicitly in each SubClass's constructor or have a function addToList in BaseClass that is called from the BaseClass constructor but overloaded in each subclass but both of those rely on future subclasses doing the same. Or I could change the newTCreated function to take an argument of type BaseClass and then cast it to type T but this doesn't give a compilation error, only a runtime exception.
It seems like there should be solution but having only recently started writing Generic classes I can't find it. Thanks in advance for any help,

What is the syntax for calling function from class file by jsp

does anyone here knows what is the syntax of how to call a function from java class file by javascript code or any way to call it?
and where should i put the calling function code? because the function is called depend on the user click.
for example
<%=pc.functionName(a,b)%>
for the variable a and b, how can i get the value from html textbox and put it in a and b...
urgent needed...
thx

Jsp's are executed before the Html forms are created and loaded. Dont try to use a java code function calling on a javascript click. You'll have to explicitly redirect it into a servlet where in you can call the function you want.
Well! another way could be using AJAX. That seems to be powerfull enough and it might also serve your purpose.
Hope this helps

Calling a Function Pool inside a Class

Hi,
I want to call a Function Pool inside a Class Method. I am getting an Error that 'Report or Program Statement already exists' when I call the function pool in the method. can anybody help me on how to call a Function Pool inside a class method.

Hello Krish
Based on your error description I assume that you have tried to "insert" the function pool program (e.g. function group ZFUNC -> SAPLZFUNC) into your class.
You cannot do that. The explanation for the error message is a following:
- The class contains already a program statement (CLASS-POOL). If there is somewhere in the class an additional program statement (e.g. FUNCTION-POOL) you will get the error.
In addition, you cannot "call" a function pool. Instead you can always call the function modules of your function group.

How to call function module/ class method of another system.

Suppose now i am working in System A. And i need to check the system Status of System B, System C, System D....
my design is to provide an interface. and each system realize the interface individually.now my question is how cani call the interface, because they are in different systems.
of course i know about the host name, port and logon information over these systems.
who can give my some suggestions or other solutions.
thanks in advance.
Johnney.

Hello,
If u want to call a FM of the other system then that FM should be a RFC enable on one.
<b>CALL FUNCTION func DESTINATION dest.</b>
Effect
Executes the function module from an external source (as a Remote Function Call or RFC); dest can be a literal or a variable.
Depending on the specified destination, the function module is executed in another R/3 or R/2 System. Externally callable function modules must be flagged as such in the Function Builder (of the target system).
Since each destination defines its own program context, further calls to the same or different function modules with the same destination can access the local memory (global data) of these function modules.
To maintain existing destinations, choose Tools -> Administration, Administration -> Network -> RFC destinations
Note
Under certain circumstances, an RFC may trigger a database commit. For this reason, RFCs must not be used between pairs of SQL statements that open and close a database cursor (such as SELECT... ENDSELECT).
