Creating a method with ByRef parameter

Hi All,
when i am creating a method with parameter as ByRef, i am getting the message as fallows.
Please use valid signature.
help me to overcome frojm this.
Thanks in advance.
With Regards
Raju

Hi,
strange... I even thought that ByRef is default parameter type for sub... maybe you can try this.
Or try to create your sub directly in the project file, maybe then you will have a proper error message from MS.

How to create a method with an interface parameter?

Hi there.
I would create a method with an interface parameter. I mean this:
public interface MyInt {
    public void method(int i);
public class SubClass implements MyInt {
    public void method(int i) {
        System.out.println("The number is: " + i);
public class MainClass {
    public MainClass(MyInt inter) {
        inter.method(10);
    public static void main(String[] args) {
(*)     new MainClass(new SubClass());
}I tried to compile this but do not work (incompatible types on (*)) . Is it possible to do something like that or not?

I compiled and runned this code on my machine and it works fine.
How did you did to compile and run this code ?
Did you put each code on its own file or all codes in the same file ?
I did like this:
I put each code in its own file and put all in the same dir, after I did:
javac -classpath . MainClass.java
After that, I did:
java -classpath . MainClass
I hope this help you

Enhance method with new parameter

How can I enhance an existing method with a new Parameter?
In some tutorial is written that this should be possible. But there is no exact description.

Thx Rich Heilman
but in the Doku "Enhancements to Global Classes and Interfaces"
http://help.sap.com/saphelp_nw70/helpdata/en/58/4fb541d3d52d31e10000000a155106/content.htm

How can I create a method with throws instruction

Hello Everybody!
How can I create this method inside WebDynpro.
I enter "throws CloneNotSupportedException" manually an it removes always.
What is wrong ?
public java.lang.Object clone( ) throws CloneNotSupportedException{
    //@@begin clone()
     __Tdag__Is_Charactconfig that= (__Tdag__Is_Charactconfig)super.clone();
       return that;
    //@@end
Regards
sas

I only checked in my 7.1 IDE and there this section exists.
If it does not exist in your IDE, just create the method manually in the //@@begin others ... //@@end user-coding-area at the end of the controller class. This solves the issue for methods that are called from inside the controller. For public methods to be called from other controllers, this will not help.

Using Java Reflection to call a method with int parameter

Hi,
Could someone please tell me how can i use the invoke() of the Method class to call an method wiht int parameter? The invoke() takes an array of Object, but I need to pass in an array of int.
For example I have a setI(int i) in my class.
Class[] INT_PARAMETER_TYPES = new Class[] {Integer.TYPE };
Method method = targetClass.getMethod(methodName, INT_PARAMETER_TYPES);
Object[] args = new Object[] {4}; // won't work, type mismatch
int[] args = new int[] {4}; // won't work, type mismatch
method.invoke(target, args);
thanks for any help.

Object[] args = new Object[] {4}; // won't work, type
mismatchShould be:
Object[] args = new Object[] { new Integer(4) };The relevant part of the JavaDoc for Method.invoke(): "If the corresponding formal parameter has a primitive type, an unwrapping conversion is attempted to convert the object value to a value of a primitive type. If this attempt fails, the invocation throws an IllegalArgumentException. "
I suppose you could pass in any Number (eg, Double instead of Integer), but that's just speculation.

Dynamic Imagelink Component - Calling Impl method with input parameter

Hi All,
I have requirement where Imagelinks are created dynamically on the pageload. Generated the components and the components are displayed on the jspx.
Now when I click the image link, a method in AMImpl should invoke and this method takes some input parameters.
I am able to call the method successfully in AMimpl with the help of below code. But I could not understand how to pass the input parameters to that method.
                           RichCommandImageLink lockimageLink =
                            new RichCommandImageLink();
                        lockimageLink.setIcon("icon.png");
                        lockimageLink.setId("icon" + index);
                        MethodExpression me =
                            JSFUtils.getMethodExpression("#{bindings." +
                                                         "MyMethodName" +
                                                         ".execute}");
                        lockimageLink.addActionListener(new MethodExpressionActionListener(me));
public static MethodExpression getMethodExpression(String name) {
   Class [] argtypes = new Class[1];
   argtypes[0] = ActionEvent.class;
   FacesContext facesCtx = FacesContext.getCurrentInstance();
   Application app = facesCtx.getApplication();
   ExpressionFactory elFactory = app.getExpressionFactory();
   ELContext elContext = facesCtx.getELContext();
   return elFactory.createMethodExpression(elContext,name,null,argtypes);
} Can some one please suggest how to pass input parameters to the Impl method.

You can use the below method to call an AMImpl method. You can pass parameters as well to the AMImpl method.
DCBindingContainer bindings = getDCBindingContainer();
OperationBinding ob = bc.getOperationBinding("MyMethodName");
Map m = ob.getParamsMap();
ob.put("paramName", "paramValue"); paramName is the parameter in AMImpl and paramValue is the value to be passed.
ob.execute();
Where getDCBindingContainer() is:
public DCBindingContainer getDCBindingContainer() {
ExpressionFactory exprFactory;
ELContext elContext;
ValueExpression valueExpression;
DCBindingContainer dcBindingContainer;
FacesContext facesContext = FacesContext.getCurrentInstance();
exprFactory = facesContext.getApplication().getExpressionFactory();
elContext = facesContext.getELContext();
valueExpression =
exprFactory.createValueExpression(elContext, "#{bindings}",
Object.class);
dcBindingContainer =
(DCBindingContainer)valueExpression.getValue(elContext);
return dcBindingContainer;
Hope this helps

How to do this: Link which calls a methode with a parameter?

Hello!
I have a small question:
I have a jsp-site with some beans.
On the jsp-site I have the following code which isnt functional:
<c:forEach items="${filter.resultlist}" var="result">
    <c:url action="#{filter.selectedAoid(result.aoid)}">
         <c:out value="${result.name}" / >
     </c:url>
</c:forEach>-> As you can see:
I want to make a Link, which is named like the String in the List and accessable by ${result.name} and on a click it should run "filter.selectedAoid()" with an int Parameter.
(So I can access the right object with my Aoid-identifier...)
The List comes from a DB and I am able to access the values of the Objects in the list.
Could someone please tell me how that is done?
Thanks in advance

One way of hacking this problem is by dynamically updating the job step which executes the stored procedure to include the parameters the user provided. You can do so by using
msdb.dbo.sp_update_jobstep.
So for example, you could create a job named "Test job" and in that job the first step would be to execute your stored procedure. You would then use the following code to update that step at run time:
execute msdb.dbo.sp_update_jobstep
@job_name = N'Test job',
@step_id = 1,
@command = 'execute my_proc @my_variable = ''my_value'''
You'd then use sp_start_job like so:
execute msdb.dbo.sp_start_job @job_name = 'Test job'
Your job would then execute using the value provided at run time for the @my_variable parameter.

Create DATA ELEMENT with passing Parameter

Dear All,
When we create the Data elementt in tcode SE61, normally we will write the text inside the text area. How about can we pass the paramater to the data element in tcode SE61 ?
Example i pass the parameter with the text "Tesing 123" , so the Data element will display Testing 123 when being called. The text flexible.
Thank

I did following steps
1. SE11
2. Data Element
3. and settings of particular data element what ever is required.
My question is how can I use YTPLNR as characteristic as same value of TPLNR. I want all data that is available in TPLNR. I am creating new element because of data length issue.
Table: IFLOT has data element TPLNR. I want all information of TPLNR in YTPLNR how it is possible to use that info in that.
I tried to create user defined characteristics for operating concern
i want to use with reference to existing value option in user define
How can I do that

How to create a Mapping with Input Parameter?

Hi,
I have a target table where the primary key column should be loaded with an Input parameter value. How can we implement this? Let me know if any examples are available?

Use a map input operator in your mapping. In the outgroup add an attribute, mapp the attribute with the column and then you can start the mapping with an extra input parameter.

PN,
First, it's impossible to create static method with WD IDE designers for controllers.
Next, if you simply need to call method from wdDoModifyView, just create instance method createHTMLViewer in regular way then call it from wdDoModifyView via wdThis.createHTMLViewer().
Third, you may create this method manually directly in source code, just place it at the end of controller between comments //@begin other ... //@end.

Report with user parameter is not runnig

Hi
I have created the report with user parameter p_deptno and qyery"select * from emp where depno=:p_deptno";
when i run the report in paper layout a popup kind page will open and ask us to enter the deptno and based on input parameter it fetches record in report.
if i tried the same thing with url :http://localhost:portno/reports/rwservlet?destype=cache&desformat=pdf&report=emp.jsp&userid=scott/tiger@orcl
the parameter window not opening and and blank report will open with coloumn headings.
help me to solve the problem.
i am using devsuite oracle10g release 2 on linux(OEL4).

Hello,
You have to provide the parameter in the URL :
For example :
http://localhost:portno/reports/rwservlet?destype=cache&desformat=pdf&report=emp.jsp&userid=scott/tiger@orcl&p_deptno=10
or use the Web parameter Form :
http://localhost:portno/reports/rwservlet?destype=cache&desformat=pdf&report=emp.jsp&userid=scott/tiger@orcl&paramform=true

A question about a method with generic bounded type parameter

Hello everybody,
Sorry, if I ask a question which seems basic, but
I'm new to generic types. My problem is about a method
with a bounded type parameter. Consider the following
situation:
abstract class A{     }
class B extends A{     }
abstract class C
     public abstract <T extends A> T someMethod();
public class Test extends C
     public <T extends A> T someMethod()
          return new B();
}What I want to do inside the method someMethod in the class Test, is to
return an instance of the class B.
Normally, I'm supposed to be able to do that, because an instance of
B is also an instance of A (because B extends A).
However I cannot compile this program, and here is the error message:
Test.java:16: incompatible types
found   : B
required: T
                return new B();
                       ^
1 errorany idea?
many thanks,

Hello again,
First of all, thank you very much for all the answers. After I posted the comment, I worked on the program
and I understood that in fact, as spoon_ says the only returned value can be null.
I'm agree that I asked you a very strange (and a bit stupid) question. Actually, during recent months,
I have been working with cryptography API Core in Java. I understood that there are classes and
interfaces for defining keys and key factories specification, such as KeySpec (interface) and
KeyFactorySpi (abstract class). I wanted to have some experience with these classes in order to
understand them better. So I created a class implementing the interface KeySpec, following by a
corresponding Key subclass (with some XOR algorithm that I defined myself) and everything was
compiled (JDK 1.6) and worked perfectly. Except that, when I wanted to implement a factory spi
for my classes, I saw for the first time this strange method header:
protected abstract <T extends KeySpec> T engineGetKeySpec
(Key key, Class<T> keySpec) throws InvalidKeySpecExceptionThat's why yesterday, I gave you a similar example with the classes A, B, ...
in order to not to open a complicated security discussion but just to explain the ambiguous
part for me, that is, the use of T generic parameter.
The abstract class KeyFactorySpi was defined by Sun Microsystem, in order to give to security
providers, the possibility to implement cryptography services and algorithms according to a given
RFC (or whatever technical document). The methods in this class are invoked inside the
KeyFactory class (If you have installed the JDK sources provided by Sun, You can
verify this, by looking the source code of the KeyFactory class.) So here the T parameter is a
key specification, that is, a class that implements the interface KeySpec and this class is often
defined by the provider and not Sun.
stefan.schulz wrote:
>
If you define the method to return some bound T that extends A, you cannot
return a B, because T would be declared externally at invocation time.
The definition of T as is does not make sense at all.>
He is absolutely right about that, but the problem is, as I said, here we are
talking about the implementation and not the invocation. The implementation is done
by the provider whereas the invocation is done by Sun in the class KeyFactory.
So there are completely separated.
Therefore I wonder, how a provider can finally impelment this method??
Besides, dannyyates wrote
>
Find whoever wrote the signature and shoot them. Then rewrite their code.
Actually, before you shoot them, ask them what they were trying to achieve that
is different from my first suggestion!
>
As I said, I didn't choose this method header and I'm completely agree
with your suggestion, the following method header will do the job very well
protected abstract KeySpec engineGetKeySpec (Key key, KeySpec key_spec)
throws InvalidKeySpecException and personally I don't see any interest in using a generic bounded parameter T
in this method header definition.
Once agin, thanks a lot for the answers.
