How to pass a variable from one class to another class?

Hi,
Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
class A {
int a;
int doA() {
      a = a + 1;
      return a;
class B {
int b;
A r = new A();
r.a; // error: <identifier> expected. What does that mean ?
int doB() {
     int c = b/a; // error: operator / cannot be applied to a
}Thank you!

r.a; //syntax error
}Why? Class definition restricts what you can define within a class to a few things:
class X {
    Y y = new Y(); //defining a field -- okay
    public X() { //defining a constructor -- okay
    void f() { //defining a method -- okay
}... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
This is also illegal syntax:
int doB() {
      A r = new A();
      r.a; // error: not a statement
}Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that.

Hi
you can use function module
data   ls_input_container TYPE swr_cont.
data   lt_input_container TYPE TABLE OF swr_cont.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
    EXPORTING
      task            = ptask
    IMPORTING
      return_code     = lv_return_code
      new_status      = lv_new_status
    TABLES
      input_container = pinput_container
      message_lines   = lt_message_lines
      message_struct = lt_message_struct.
where you pass the data in imnternal table "pinput_container" as
ls_input_container-element = 'KUNNR'.
ls_input_container-value = ls_skna1-kunnr ."wd_this->lv_kunnr.
APPEND ls_input_container TO lt_input_container .

HOW TO PASS THE DATA FROM SELECTION SCREEN TO STANDARD TRANSACTION?

HI,
HOW TO PASS THE DATA FROM SELECTION SCREEN TO STANDARD TRANSACTION?
thanks,
samba.

By selection screen, what do you mean? There is no selection screen in WDA as there was in classic dynpro. Do you mean you are using the Select-Options reusable component? Are you wanting to call a standard transaction via ITS - SAPGUI for HTML? Please provide more details to your question.

How to pass the value from Sub report to main report

I have un report(mainreport) within a subreport(subreport).
With reporting services, how to pass the value from Sub report to main report?
thanks

Hi Alebet,
With reporting services to pass values from sub report in to main report is not supported directly.
But there are some workarounds through which you can get this .
There are two ways to get this.
1- Put your sub report query into some table. i mean to say through the subreport query get some temporary table.
2- Using this temporary tables data write some Scala function in the data base.
3- Now in your main report query return this scala function as a column.
4- Extract the column value where ever you want in your main report which is getting calculated from the subreport query. so you will be getting the values returned from the subreport in the main report.
This will definitely work fine as i have done some report in this way.
Another way of doing is that
1- prepare another data set with the same query as in sub report in the data tab.
2- then refer this 2nd dataset in your main report .
But better way will be the top one.
Anyway please let me know if you get the solution.
Thanks
Mahasweta

How to pass the data from a input table to RFC data service?

Hi,
I am doing a prototype with VC, I'm wondering how VC pass the data from a table view to a backend data service? For example, I have one RFC in the backend system with a tabel type importing parameter, now I want to pass all the data from an input table view to the RFC, I guess it's possible but I don't know how to do it.
I try to create some events between the input table and data service, but seems there is no a system event can export the whole table to the backend data service.
Thanks for your answer.

Thanks for your answer, I tried the solution 2, I create "Submit" button, and ser the mapping scope to be "All data rows", it only works when I select at least one row, otherwise the data would not be passed.
Another question is I have serveral imported table parameter, for each table I have one "submit" event, I want these tables to be submitted at the same time, but if I click the submit button in one table toolbar, I can only submit the table data which has a submit button clicked, for other tables, the data is not passed, how can I achieve it?
Thanks.

.How to instantiate the innerclass from another class with coded eg.

How to instantiate the innerclass from another class(both for static & non static) please give me an eg with coding.

It's just a preference, but I like writing factory methods:
public class Outer {
    public class Inner {}
    public static class StaticInner {}
    public Inner innerInstance() {
        return new Inner();
    public static StaticInner staticInnerInstance() {
        return new StaticInner();
    public static void main(String[] args) {
        Outer.StaticInner si = Outer.staticInnerInstance();
        Outer outer = new Outer();
        Outer.Inner i = outer.innerInstance();
}Often, for me, the inner class implements an interface, and the factory method
lets you hide the implementation class:
public class Outer {
    private class Inner implements Runnable {
        public void run() {}
    public Runnable runnerInstance() {
        return new Inner();
    public static void main(String[] args) {
        Outer outer = new Outer();
        Runnable r = outer.runnerInstance();
}

Struts - Data pass from Action class to JSP

hello ,
I am new to struts and have a strange question in my mind .
How do we pass business logic data from action class to JSP.Do we use session object or any other best way to be used to pass data.
Example scenario:
Once the user logins into application by passing userid and password ,we need to display his open queries (from database table) on jsp.
Components used :
Login.jsp
LoginForm(getter and setter methods of userid & password)
LoginAction(get database connection,perform query to fetch user's open queries form the database)
OpenQueries.jsp(to display Open queries on a tabular format)
In LoginAction - We fetched user's open Queries from the database and stored them in collection object .
My question is : what is the best way to pass Collection object from LoginAction to OpenQueries.jsp ?
Thanks in advance...

You can use plain javabeans to transfer the data. Check out the jsp:usebean tag. If you don't know how to do, check out the Java EE tutorial: http://java.sun.com/javaee/5/docs/tutorial/doc/ Using javabeans in JSP pages starts halfway chapter 4.

Hi Pradeep
Steps:
1. First create an instance for bapi and bind the instance to the bapi node.
Z<bapi name> zb=new Z<bapi name>();
wdContext.nodeZ<bapi name>. bind(zb);
2. Then if u have the import parameter u have to set them by using
    The instance of the above bapi.
    Zb.set<import parameters>;
3. If the bapi has a table parameters then the structure for the table parameters will also be imported
   In the model class.
4. Set the table parameters by creating the instance for that structure and using this instance set it.
   Z<Struct>itm tab=new Z<Struct>();
   Tab.set<table parameters>
5. Then add the structure instance to the bapi instance.
    Zb.add(Tab);
6. Then Execute the bapi after setting the import parameters.
7. If there is any export parameters, then get the values after execution.

ADF : How to pass a variable from one frame to another frame ?

Hi,
I have an html page divided into 3 frames, all inside a frameset. Each frame are linked to a specific .jsf page (src attribute). When I list a list thanks to a ADF datatable in ONE frame, each row has a "show more" button. When I click this button I succeeded to print row detail inside the same frame thanks to the processScope ADF's native variable. The problem is that I want to display the row detail in another frame, clicking from this current frame. So for this I need to reload the other frame which display the content of the processScope variable.
For this I use the javascript code :
=> parent.frames['bottomRight'].location.reload()
Just before refreshing, I put the variable in the processScope of course like it appears in the backing bean :
FacesContext context = FacesContext.getCurrentInstance();
          CLPRMBuilding building = (CLPRMBuilding)
     context.getApplication().getVariableResolver().resolveVariable(context, "building");
     if (building == null)
     return "error";
     AdfFacesContext afContext = AdfFacesContext.getCurrentInstance();
     afContext.getProcessScope().put("buildingDetail", building);
Next, when the user click on the button "show more" a binding CoreCommandButton component is done. And the accessor's code is executed :
public void setShowMoreCommandButton(CoreCommandButton showMoreCommandButton) {
          this.showMoreCommandButton = showMoreCommandButton;
          showMoreCommandButton.setOnclick("parent.frames['bottomRight'].location.reload()");
And so the other frame is reloaded ! But the "buildingDetail" variable seems not to be present in the processScope because in the jsf page displayed by the other frame no content is printed, like if the variable were not initialized. How to do then ? How to pass the buildingDetail variable to the other frame which I need to reload to refresh it's content ?
