Accessing private method of a class from report

Hello All,
I would have to access a private method of a class from a report.
Is it possible to access private mehod otherthan from its own class and friend classes.
Please guide on this. If is possible, to access please give some sample code.
Thanks & Regards,
Vishnu Priya

Hi,
By using the friend concept you can access private attribute or method in outside class.
Try the following code,
CLASS C1 DEFINITION DEFERRED.
CLASS C2 DEFINITION CREATE PRIVATE FRIENDS C1 .
PRIVATE SECTION.
DATA : NUM TYPE I VALUE 5.
METHODS : M2.
ENDCLASS.
CLASS C2 IMPLEMENTATION.
METHOD M2.
WRITE:/5 'I am method m2 in C2'.
ENDMETHOD.
ENDCLASS .
class c1 definition.
public section .
methods : m1.
endclass.
class c1 implementation.
method m1.
DATA : OREF2 TYPE REF TO C2.
CREATE OBJECT OREF2.
WRITE:/5 OREF2->NUM.
CALL METHOD OREF2->M2.
ENDMETHOD.
endclass.
START-OF-SELECTION.
DATA : OREF1 TYPE REF TO C1.
CREATE OBJECT OREF1.
CALL METHOD OREF1->M1.

Accessing private attribute of a class from its Friend Class

Hi Experts ,
Please help me to understand how can i access private attribute of one class from its friend class.
I am coding in Method (DO_SAVE) of class /BOBF/CL_TRA_TRANSACTION_MGR.
I need to access private variable ( MO_BOPF) of class /BOBF/CL_TRA_SERVICE_MGR ( Friend of /BOBF/CL_TRA_TRANSACTION_MGR ).
Regards,
Reny Richard

Hi Reny,
You should be able to access by creating object of friend class.
Sample:
data lo_frnd     TYPE REF TO /BOBF/CL_TRA_SERVICE_MGR.
data lo_compl type REF TO /BOBF/IF_TRA_TRANS_MGR_COMPL.
   create OBJECT lo_frnd
     exporting
               iv_bo_key = '111'
               IO_COMPL_TRANSACTION_MANAGER = lo_compl.
"access the private object of friend class
   clear lo_frnd->MO_BOPF.
Note: need to provide iv_bo_key & IO_COMPL_TRANSACTION_MANAGER while creating object.
Hope this helps you.

How to access private method of an inner class using reflection.

Can somebody tell me that how can i access private method of an inner class using reflection.
There is a scenario like
class A
class B
private fun() {
now i want to use method fun() of an inner class inside third class i.e "class c".
Can i use reflection in someway to access this private method fun() in class c.

I suppose for unit tests, there could be cases when you need to access private methods that you don't want your real code to access.
Reflection with inner classes can be tricky. I tried getting the constructor, but it kept failing until I saw that even though the default constructor is a no-arg, for inner classes that aren't static, apparently the constructor for the inner class itself takes an instance of the outer class as a param.
So here's what it looks like:
        //list of inner classes, if any
        Class[] classlist = A.class.getDeclaredClasses();
        A outer = new A();
        try {
            for (int i =0; i < classlist.length; i++){
                if (! classlist.getSimpleName().equals("B")){
//skip other classes
continue;
//this is what I mention above.
Constructor constr = classlist[i].getDeclaredConstructor(A.class);
constr.setAccessible(true);
Object inner = constr.newInstance(outer);
Method meth = classlist[i].getDeclaredMethod("testMethod");
meth.setAccessible(true);
//the actual method call
meth.invoke(inner);
} catch (Exception e) {
throw new RuntimeException(e);
Good luck, and if you find yourself relying on this too much, it might mean a code redesign.

Calling a method of one class from another withing the same package

hi,
i've some problem in calling a method of one class from another class within the same package.
for eg. if in Package mypack. i'm having 2 files, f1 and f2. i would like to call a method of f2 from f1(f1 is a servlet) . i donno exactly how to instantiate the object for f2. can anybody please help me in this regard.
Thank u in advance.
Regards,
Fazli

This is what my exact problem.
i've created a bean (DataBean) to access the database. i'm having a servlet program (ShopBook). now to check some details over there in the database from the servlet i'm in need to use a method in the DataBean.
both ShopBook.java and DataBean.java lies in the package shoppack.
in ShopBook i tried to instantiate the object to DataBean as
DataBean db = new DataBean();
it shows the compiler error, unable to resolve symbol DataBean.
note:
first i compiled DataBean.java, it got compiled perfectly and the class file resides inside the shoppack.
when i'm trying to compile the ShopBook its telling this error.
hope i'm clear in explaining my problem. can u please help me?

Invoke a method in one class from a different class

I am working on a much larger project, but to keep this simple, I wrote out a little test that would convey the over all theory of the program.
What I am doing is starting out with a 2 JFrames and a Class. When the program is launched, the first JFrame opens. In this JFrame is a label and a button. When the button is clicked, the second JFrame opens. This JFrame has a textField and a button. The user puts the text in the textField and presses the button. When the button is pushed, I want the text that was just put in the textField, to be displayed in the first JFrame's label. I am trying to invoke a method in the first JFrame from the second, but nothing happens. I have also tried making the Class extend from JFrame1 and invoke it from there, but no luck. So, how do I invoke a method in a class from a different class?
JFrame1 (I omitted the layout part. I made this in Netbeans so its pretty long)
public class NewJFrame1 extends javax.swing.JFrame {
     private NewClass1 nC = new NewClass1();
     /** Creates new form NewJFrame1 */
     public NewJFrame1() {
          initComponents();
          jLabel1.setText("Chuck");
     public void setLabels()
          jLabel1.setText(nC.getName());
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     NewJFrame2 j2 = new NewJFrame2();
     j2.setVisible(true);The class
public class NewClass1 {
     public static String name;
     public NewClass1()
     public NewClass1(String n)
          name = n;
     public String getName()
          return name;
     public void setName(String n)
          name = n;
}The second jFrame
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
     NewClass1 nC = new NewClass1();
     NewJFrame1 nF = new NewJFrame1();
     nC.setName(jTextField1.getText());
     nF.setLabels();
     System.out.println(nC.getName());At this point I am begging for help. I have been trying for days to figure this out, and I just feel like I am not getting anywhere.
Thanks

So, how do I invoke a method in a class from a different class?Demo:
public class Main {
    public static void main(String [] args) {
     Test1 t1 = new Test1();
     Test2 t2 = new Test2();
     int i = t1.method1();
     String s = t2.method2(i);
     System.out.println(s);
class Test1 {
    public int method1() {
     return 10;
class Test2 {
    public String method2(int i) {
     if (i == 10)
         return "ten";
     else
         return "nothing";
}Output is "ten".

How to access a method of a class which just known class name as String

Hi,
Now I have several class and I want to access the method of these class. But what I have is a String which contain the complete name of the class.
For example, I have two class name class1and class2, there are method getValue in each class. Now I have a String containing one class name of these two class. I want to access the method and get the return value.
How could I do?
With Class.forName().newInstance I can get a Object. but it doesn't help to access and execute the method I want .
Could anybody help me?
Thanks

Or, if Class1 and Class2 have a common parent class or interface (and they should if you're handling them the same way in the same codepath)...Class c = Class.forName("ClassName");
Object o = c.newInstance(); // assumes there's a public no-arg constructor
ParentClassOrInterface pcoi = (ParentClassOrInterface)o;
Something result = pcoi.someMethod(); Or, if you're on 5.0, I think generics let you do it this way: Class<ParentClassOrInterface> c = Class.forName("ClassName");
// or maybe
Class<C extends ParentClassOrInterface> c = Class.forName("ClassName");
ParentClassOrInterface pcoi = c.newInstance();
Something result = pcoi.someMethod();

Accessing object of the main class from the thread

Hi, I'm having problem accessing object of the main class from the thread. I have only one Thread and I'm calling log.append() from the Thread. Object log is defined and inicialized in the main class like this:
public Text log; // Text is SWT component
log = new Text(...);Here is a Thread code:
...while((line = br.readLine())!=null) {
     try {
          log.append(line + "\r\n");
     } catch (SWTException swte) {
          ErrorMsg("SWT error: "+swte.getMessage());
}Error is: org.eclipse.swt.SWTException: Invalid thread access
When I replace log.append(...) with System.out.println(..) it works just fine, so my question is do the log.append(..) the right way.

This is NOT a Java problem but a SWT specific issue.
It is listed on the SWT FAQ page http://www.eclipse.org/swt/faq.php#uithread
For more help with this you need to ask your question on a SWT specific forum, there is not a thing in these forums. This advice isn't just about SWT by the way but for all specific API exceptions/problems. You should take those questions to the forum or mailing list for that API. This forum is for general problems and exceptions arising from using the "core" Java libraries.

How to Access Protected Method of a Class

Hi,
I need to access a Protected method (ADOPT_LAYOUT) of class CL_REIS_VIEW_DEFAULT.
If i try to call that method by using class Instance it is giving error as no access to protected class. Is there any other way to access it..

Hi,
You can create a sub-class of this class CL_REIS_VIEW_DEFAULT, add a new method which is in public section and call the method ADOPT_LAYOUT of the super-class in the new method. Now you can create an instance of the sub-class and call the new sub-class method.
REPORT ZCD_TEST.
class sub_class definition inheriting from CL_REIS_VIEW_DEFAULT.
public section.
methods: meth1 changing cs_layout type LVC_S_LAYO.
endclass.
class sub_class implementation.
method meth1.
call method ADOPT_LAYOUT changing CS_LAYOUT = cs_layout.
endmethod.
endclass.
data: cref type ref to sub_class.
data: v_layout type LVC_S_LAYO.
start-of-selection.
create object cref.
call method cref->meth1 changing cs_layout = v_layout.

How to call a method in IMPL class from one context node

Hi, I´ve been only study the posibility to access a method in the IMPL class from one context node class...CN## without using events, is there a way to call it ??? I don´t have it as requierement just learning thanks !.

Hi,
Try this by following this you can get the custom controller instacne in the view context nodes, for your requirement you can keep the view implementation class instance instead of cuco..
To get the custom controller instance in Context node getter/setter method:
1. Declare Cuco instance reference variable in ctxt class..
2. Set this cuco ref. in the Create context node method of ctxt class:
try.
gr_cucoadminh ?= owner->get_custom_controller( 'ICCMP_BTSHEAD/cucoadminh' ). "#EC NOTEXT
catch cx_root.
endtry.
you can avoid this step as this is not needed in case of view isntance
3. Assign this instance to the respective context node Create method using:
BTStatusH->gr_cuco ?= gr_cucoadminh. " here assign the view implementation ref. " me" instead of gr_cucoadminh
Here gr_cuco is the ref. variable of custom controller in the respective context node for eg. BtstatusH
Sample implementation of this can be found in
ICCMP_BTSHEAD/BTSHeader ->context node BTACTIVITYH-> attr ->GR_CUCO(instance of cuco)

Referencing a method in one class from a constructor in another?

Hi,
I'm not sure whether this is a simple question or not, but instead of rewriting the method in another class, is there a way that I can reference that method, eg:
public int getTitleCode() {
        return titleCode; }within the constructor of another class. I don't want to use inheritance with this because it would change all my existing contructors.
Any ideas how to do this, or is it just simpler to add the method to both classes?
Many thanks!

Hi,
I'm trying to use a method, defined in Class A, within one of the constructors in Class B. Class B object represents a copy of the output of Class A, with the addition of a few extra methods.
Therefore to represent the details correctly in the saved text file for class B, I need to call a method from class A to save the text file for class B correctly.
Class B saves a file with a reference number unique to that class, plus a reference number that is also saved in the text file for class A.
I can achieve the correct result for the above by having the same method in both classes, but I just wondered whether instead of this I could in fact call the method from class A in the constructor for class B. With the following code,
    referenceNumber = refNum;
        titleReferenceNumber = titleRefNum;
        titleRefNum = titles.getTitleCode();
    }I just get a 'nullpointerexception' when I try to run this in the main class.
Any help or advice appreciated!

How to call main method in one class from another class

Suppose i have a code like this
class Demo
public static void main(String args[])
System.out.println("We are in First class");
class Demo1
public static void main(String args[])
System.out.println("We are in second class");
In the above program how to call main method in demo calss from Demo1 class......???????

No, i dont know how to call other than main methods from other classes
And one more doubt i have i.e. Like in C can we see the execution of the program like how the code is being compiled step by step and how the value of the variable changes from step to step like(Add Watch).........

SSRS 2012 - Cannot access any of the sub page from Report Manager - Manage page menus.

All:
It was working at one point of time, but suddenly when I tried to access any of the menus from Report Manage page, all the options (Data Source, Subscriptions, Processing Options, Cash Refresh Options, Report History, Snapshot Options, Security) will
redirect back to the root directory page.
Because of this problem, I cannot manage any of the options or subscriptions for any of my report on the server.
Does anybody know what could be the problem? Thank you very much for your help.
Tina

Hi Tina,
As per my understanding, I think this strange issue can be caused by the browser which running Report Manager and the page files may be corrupted which are related to manage properties in Report Manager.
As to the browser, if you use IE explorer to run Report Manager, I suggest that you can try to run it in compatibility mode. If you are using another browser, I recommend that you should use IE explorer to run Report Manager to check the issue again.
Another possibility is related to corrupted page files. If in this scenario, I suggest that you can try to copy the all Pages folder from another server which works well to replace the current one. By default, the Pages folder is located in the following
folders:
C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportManager
Besides, if this issue still exists, you can go to Reporting Services Log Files to see if there are error messages. Then it may help us make further analysis.
Hope this helps.
Thanks,

To access a method frm a class derived frm a base class with the same name

Here' s an example:-
class TestA {
public void start() {
System.out.println("TestA");
class TestB extends TestA {
public void start() {
System.out.println("TestB");
}In main method I do this:-
TestA testA = new TestA();
TestB testB = new TestB();
((TestA)testB).start();Output :-
TestB.
Now when i define the method as static :-
class TestA {
public static void start() {
System.out.println("TestA");
class TestB extends TestA {
public static void start() {
System.out.println("TestB");
}Then output is :-
TestA.
Can anyone let me know that when i say ((TestA)testB).start(); i.e i am type casting TestB obect to it base call then TestA should be printed but it doesn't print but when i declare method as static is does print TestA.
Thanks,
Heena

>
>
Secondly, when i say ((TestA).testB).start(); output is TestB. But when i define start() method as static output is TestA. I need clarity for the same.In the static case, all that the compiler is interested in is the class of the expression before the ".". Because you've put in an explicit cast the type of expression is assumed to be TestA the compiler doesn't know what kind of object will actually be referenced at runtime. In the static case which method is called is determined at compile time.
In the instance method case what determines the method called is determined the class of the actual, run time, value of the expression, and despite your cast, the actual value is still a reference to a TestB instance, so the TestB method is called. In the instance case which method called is determined at run time.

How to call a static method of a class from another class?

Hello,
I have two classes in a package. The first one
package my package;
public class class1
protected static ImageIcon createIcon(String path)
The second one
package my package;
public class class2
private ImageIcon image1;
image1 = class1.createIcon("/mypath");
This does not work since class2 cannot load the appropriate image. Where do I have to define the ImageIcon variables in class one or two and do they have to be static variables?
Thanks in advance
Christos

If the two classes are in the same package, that will work, in fact. A trivial example:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
// Note: Member of the same package
package foo;
public class Foo2 {
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}However, if they are in different packages that won't work - the protected keyword guarantees that only classes derived from the class with the protected method can access it: Therefore this will not work:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
package foo.bar;
public class Foo2{
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}But this will:
package foo;
public class Foo1 {
     protected static String getString() {
          return "World";
package foo.bar;
public class Foo2 extends foo.Foo1 {
     public static void main(String[] argv) {
          System.out.println("Hello "+ foo.Foo1.getString());
}I think you should read up a bit more about packages and inheritance, because you're going to have a lot of trouble without a good understanding of both. Try simple examples first, like the above, and if you hit problems try to produce a simple test case to help you understand the problem rather than trying to debug your whole application.
