How to use a List interface?

Hi,
anybody can help me about using List interface?
I need one example please.
Thanks in advance and excuse me for my english.
Daniele.

List interface is useful when you want to provide an access to a data structure without exposing implementation details. For example :
public class Storage {
private ArrayList _list;
public List getList () {
return ArrayList;
}If one day you prefer to use a LinkedList instead of the ArrayList, the classes using "Storage" won't need to be modified.
Hope this helps,
Matthieu

How to use dynamic list box in survey builder?

Hello,
Could someone give me a little bit of thread? How to use dynamic list box in survey builder?

Hi Liu,
Dynamic combo boxes::A combo box is dynamic if it references a document property for which a value set is defined in the configuration (System Administration ® System Configuration ® Content Management ® Global Services ® Property Metadata ® Properties ® Parameter Allowed Values).
At runtime (when you open the creation form) the system reads these values from the configuration and displays them in the dropdown list.
If you link a combo box for which list entries already exist to a document property with a value set, the system asks whether you want to delete the list entries. it is recommend that you accept this suggestion and delete the list entries from the XML Forms Builder. Otherwise inconsistencies could arise between the entries in the XML Forms Builder and the value set in the configuration. This can cause errors when saving.

CcBPM - How to use 1 Message Interface for 2 different Business System

Hi,
I have this bpm scenario below :
JDBC QUERY (ASYN) ---> RFC (SYNC) -
> JDBC INSERT (ASYN) -
> MAIL (ASYN).
So Both JDBC INSERT and MAIL using the same data input from RFC response for instance i will named as MI_RFC_RES_ASYN_ABS. I have problem to configure in the integration directory, how make the xi smart enough to routing in the correct business system.
JDBC -
> BS_JDBC and MAIL -
> BS_MAIL base on the send step in BPM because the interface is the same.
Cheers
Fernand

Hi,
If you want to send the same mesg to diff systems and also need to have the control on seq,
then define 2 diff abstract interfaces for messages going out of BPM (with same message type so that structure is same).
One will be used to define send step for JDBC and other for BPM.
Define 2 send steps in BPM one for JDBC and other for mail using these abstract interfaces.
Now you will have 2 receiver determinations.
Since recr is determined based on sender system interface name and name space,
system name ( BPM ) and name space will be same for both the messages going out of BPM.
for JDBC abstract interface BS_JDBC will be recvr.
and for Mail abstract interface BS_MAIL will be your receiver.
hope it answers your qn.

How to use the List in this case.

I got sample code from http://developer.java.sun.com/developer/technicalArticles/ThirdParty/WebCrawler/. But when I compiled it, there was error message like "webcrawler.java:16: reference to List is ambiguous, both class java.util.List in java.util and class java.awt.List in java.awt match List listMatches; "
I think it might be because it was written by JDK1.1.3. I am using JDK1.4 to compile it. Can any body tell me how to make it can be compiled by JDK1.4?
Thanks a lot.

Hi olivia16
There is an interface called java.util.List and a class java.util.List :-)
To correct source code just put java.util. prefix at lines 16 and 76:
java.awt.List listMatches; // 16
listMatches = new java.awt.List(10); // 76

How to use the Comparable Interface?

Now I have a question and I don't quite understand what the book explains. How does the comparable interface work? How can you redefine the equals implementation? How can you implement a compareTo? and how does this works with arrays? Thanks amigos......

Not sure how to answer your question "how does the Comparable interface work" - what do you mean by "work"? It's purpose is to supply a known method that can be used to define an ordering on lists of objects. To do this you need to know how two objects compare to each other (less than, equal to, greater than) - and that's what the compareTo method gives you.
You redefine the equals implementation by overriding the equals method - just declare a method in your class that has the same signature as equals and you're good.
Your implementation of compareTo depends on your class. You just need to define how your classes compare to each other - for instance, assume you have an "Employee" class, that has an employee number and first name and last name fields. You want the natural ordering of lists of Employees to go in order by employee number. Define your compareTo method like:
public int compareTo(Object o) {
    Employee emp = (Employee)o;
    if (emp.getEmployeeNumber() < this.getEmployeeNumber()) {
        return -1;
    else if (emp.getEmployeeNumber() == this.getEmployeeNumber()) {
        return 0;
    else {
        return 1;
}You can sort arrays of things via the Arrays.sort method, which takes the array to sort and a Comparator (not Comparable) reference. The Comparator interface provides the same idea as the Comparable interface, but it's a stand-alone object that handles the comparison, as opposed to a method of some particular class. The compareTo method of the Comparator interface takes two Object references and returns how they compare.
Good luck

How to use functions in interfaces

Hi.
I have an interface but one target field has to be filled by a function that converts the source field to date and in case of exceptions returns null.
I have created the function and grant the correct privileges to the ODI user.
Then in the interface i wrote - MY_FUNCTION(source_field) - in the definition of the target field like i write for example TO_NUMBER(source_field) but it doesn't work.
Please help me to know how can i resolve this problem

I am not sure what you are trying to accomplish , here is the steps ,if you are trying to write a function for to_number .
Call your Function TO_NUM
In the implementation syntax write this - TO_NUMBER($(COLUMN_NAME)) and copy the same in
Implementation ,select the technology Oracle . Apply and
Call the function in Mapping this way - TO_NUM(<COLUMN_NAME>)
try this and let me know if you are looking for some thing else.

How to use price list in inventory management documents (without SO module)

Hi all
I want to setup sales prices for items and I am using inventory management module of jd edwards enterpriseone.
Is there any possibility in which I can use the sales price items functionality.
So after I enter the sales price for each items in specific conditions, is there any possibility for these prices to be automatically shown anytime I enter a inventory issue or any other document which has to do with the issuing of the items.
Please suggest
thank you and best regards
Ernest

Hello,
You can setup Item Sale price through the P4106 application in inventory management. But since your requirement is quite customised, Inventory Issue dont have such functionality to populate Item Sale Price when you are issuing items eventhough you create/change doctype. It will only be populate Item Cost and Extended cost.

How to use array list with fixed values to insert record in trigger

I have a list of number 1,30,40,45,60 . These numbers are not being changed so I don't need to keep in a table. So have to create a after insert trigger for
As
Begin
@list = 1,30,40,45,60 // Array value
for i=1 to @list.count
Insert into mappingtable(arrayvalue,itemcode) values (list[i],Inserted.Itemcode)
Next
End
Please can you help with a code
Regards
Pol
polachan

Be careful what you assume - rarely are lists of values like this truly static. One thing to keep in mind that arrays in sql server are tables. So, one example is:
set nocount on;
/* represents the virtual inserted table in your trigger */
declare @inserted table (itemcode char(4));
insert @inserted (itemcode) values ('ABCD'), ('JJKL');
select * from @inserted;
select * from @inserted cross join (values (1), (30), (40), (45), (60)) as arrayx(value);
