[SwingWorker] how to return a jPane from SwingWorker
Lets say I have a table on left split plane.
When a user clicks on it, I and the right pane to be populated w/ data (its a JGoodies builder repeater).
Since I access data, I use swing worker.
So... the right pane needs to return a jPane that I compute in a swing worker.
Fine, but... like how?
I see swingworker return object, but how do I then add that pane.
tia,
.V
Not got all your meanings.
But you can do the thing after you finish the thing in construct() method in SwingWorker.
I think may be helpful.
Good Luck!

[UIX] How To: Return multiple values from a LOV
Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
model="${bindings.DepartmentId}"
id="${bindings.DepartmentId.path}"
destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
model="${bindings.DepartmentId}"
id="DepartmentId"
destination="departmentsLov.uix"
partialRenderMode="multiple"
partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
id=DepartmentName
model="${bindings.DepartmentName}"
columns="10"
disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
<compound>
<set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
<set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
</compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
<compound>
<set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
<set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
</compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards

How to return multiple values from dialog popup
hi all
I'm using ADF 10g. I have a requirement that I have to return multiple values from a dialog.
I have a page containing a table with a button which calls the dialog. The dialog contains a multi-select table where i want to select multiple records and add them to the table in the calling page.
In the backing bean of the calling page, I have the returnListener method.
I am thinking that I have to store the selected rows from dialog in an array and return that array to the returnListener...but I don't know how to go about it with the code.
Can someone help me out with it?
thanksHi Frank,
I'm trying to implement your suggestion but getting comfused.
AdfFacesContext.getCurrentInstance().returnFromDialog(null, hashMap) is called in ActionListener method, from what I understood.
ReturnListener method already calls it, so no need to call explicitly.
Okay here's what i'm doing.
command button launches the dialog on the calling page.
In the dialog page, there is a button "select", which when i click, closes the dialog and returns to calling page. I put a af:returnActionListener on this button, which logically should have a corresponding ReturnListener() in the calling page backing bean.
Now I have 3 questions:
1. do i have to use ActionListener or ReturnListener?
2. where do I create the hashMap? Is it in the backing bean of the dialog or in the one of calling page?
3. how do I retrieve the keys n values from hashmap?
please help! thanks
This is found in the backing bean of calling page:

Newbie question on how to return java objects from java stored procedures
Hi,
As you may guess, i'm new to this.
I have a stored procedure that does some calculations and creates a list of java objects as the result of the query.
How would I return the list from the database to the client application?
Would I have to create an Oracle type that maps to the java object?
Please help.
JagHi Jag,
Your question is very vague (to me). Perhaps you could post what you have done so far? Have you tried looking through the Sample Code page of the Technet Web site, or tried searching the Ask tom Web site, or MetaLink?
Good Luck,

How to return a object from a method in a java program to a C++ call (JNI )
Sir,
I am new to java and i have been assigned a task to be done using JNI.
My question is,
How can i return an object from a method in a java program to a call for the same method in a C++program using JNI.
Any help or suggesstions in this regard would be very useful.
Thanking you,
Anjan KumarHello
I would like to suggest that JNI should be your last choice and not your first choice. JNI is hard to get right. Since the JNI code is executing in the same address space as the JVM, any problems (on either side) will take down the entire process. It dilutes the Write Once Run Anywhere (WORA) value proposition because you need to provide the JNI component for all hardware/OS platforms. If you can keep your legacy code(or whatever you feel you need to do in JNI) in a separate address space and communicate via some inter-process channel, you end up with a system that is more flexible, portable, and scalable.
Having said all that, head over to the Java Native Interface: Programmer's Guide and Specification web page:
http://java.sun.com/docs/books/jni/
Scroll down to the Download the example code in this book in ZIP or tar.gz formats. links and download the example source. Study and run the example sources. The jniexamples/chap5/MyNewString demo creates a java.lang.String object in native code and returns it to the Java Language program. -

How to return custJava Object from Java Stored Function/Procedure to Java Application
I WILL PAY $100 FOR SOLUTION.
Oracle JDBC documentation gives step by step on how to return Oracle Type Object to Java Application. No question here.
But is it possible to create Java Stored Function [getMyClass() ] which returns CUSTOM Java based object [MyClass] to Java application like:
//java stored function
class Foo
public static MyClass getMyClass()
return new MyClass();
//java class I want to return to Java

public String getGreetings(String name)
return "Hello " + name;
I tried to do it using intermittent Oracle

not get throgh meaningless run time ORA Errors. Any kind of help would be greatly
appreciated. If you know the answer please
post it or e-mail [email protected]
nullYou don't say which version of the database you are on. There's an interesting looking article on OTN on handling CLOBs in JDBC in 10g. It may well be useful for earlier versions too (but no guarantees).

How to return a char [][] from c++ to java with JNI
hi , i am new to JNI and i am having some troubles with a special task :
in fact i am supposed to treat some data stored in a char[100][100] value and then return the result to java , the result is the sam value bur modified i mean a char [100][100] variable too...
i saw that we can rely on
JNIEXPORT jobjectArray JNICALL Java_JNITest_newArray (JNIEnv *env, jclass, jint size )
jobjectArray joa = ... ); // what in my case ?;
jsize len1 = (jsize)env->GetArrayLength(joa);
for (int i=0; i<l en1; i++)
jintArray colonne = (jintArray)env->GetObjectArrayElement(joa, i);
jsize len2 = (jsize)env->GetArrayLength(colonne);
jint *element = env->GetIntArrayElements(colonne, 0);
for(int j=0; j<len2; j++)
jint res = element[j];
// process some treatment here
// how now to return the result to java : joa modified !!
[/code]
may be some errors present in this piece of code ...but i rely on your help to have the solution!! please i am really desperated !You know that any JNI function for an array handles or creats only one-dimensional array. But if you know Java array structure then with these functions you can create Java arrays of any dimensions.
A Java multi-dimensional array is a set of nested one-dimensional arrays (consider dimensions from left to right). I give you only schema of this process. Let create the array of your type (for example, char [2][3]):
1) create one-dimensional object array "[C"[/b] of size two for the first dimension (and assign it to some variable of type jobjectArray) ;
2) create two three-dimentional char arrays and assign these local references to each element of the array created in prev. step;
3) fill each array created in (2) with your data (characters);
4) return to Java code the reference created in the step (1) and do not delete local references created in steps (1) and (2). -

781509790 Computer 102 9/7/2006 5:13:11 PM Joe DoeHi,
Instead of creating varray, create a table type of objects for both courses as well as students like below.
create or replace type course_obj as object
name varchar2(20),
start_date date,
instructor varchar2(20)
create or replace type course_arr
as TABLE OF course_obj;
create or replace type student_obj as object
first_name varchar2(50),
last_name varchar2(50),
student_number number,
courses course_arr
create or replace type student_arr as TABLE OF student_obj
Then create a pipelined function like below,
CREATE OR REPLACE FUNCTION get_student_info ( student_number in number )
RETURN student_arr PIPELINED IS
student_arr1 student_arr:=student_arr();
course_arr1 course_arr:=course_arr();
i number:=0;
BEGIN
i:=i+1;
course_arr1.extend;
student_arr1.extend;
course_arr1(course_arr1.count) := course_obj('maths',sysdate,'vv2');
student_arr1(student_arr1.count) := student_obj('raja','ram',23232,course_arr1);
PIPE ROW(student_arr1(i));
course_arr1(course_arr1.count) := course_obj('computer',sysdate,'vv');
student_arr1(student_arr1.count) := student_obj('raj','raam',223232,course_arr1);
PIPE ROW(student_arr1(i));
END;
You'll get the result like below,
FIRST_NAME LAST_NAME STUDENT_NUMBER
COURSES(NAME, START_DATE, INSTRUCTOR)
raja ram 23232
COURSE_ARR(COURSE_OBJ('maths', '08-SEP-06', 'vv2'))
raj raam 223232
COURSE_ARR(COURSE_OBJ('computer', '08-SEP-06', 'vv'))

How to return course data from different tables from a procedure
I have a procedure which must return information from two tables:
The sturcture of tables is as below:
Table 1:
id,
name,
property,
type
Table 2:
id1
id2 ,
property.
id1 of table2 refers to id attribute of table1. ie id is the foreign key for table2.
the tables are defined such that for corresponding to each id in table1 there would
be two or more rows in table2.
Now in the procedure given the id, i need to retrieve information from table1 and also all the rows in table2 which refers to id2.I want to return a cursor.How can i do this.
eg:
if table 1 has an entry with id 2
and table 2 has three entries with id1 referring to id(i.e id1=2)..I need to return the table1 entry with id=2 and three entires from table2 with id1=2.
If cursors are not appropriate, what other alternative methods can be used.
Any suggestions would be of great help.thanks for the reply,
The result set would be returned to the client .....which would do further processing.The client does not even know that the data is organized in two tables..Therefore given an id, client would expect to have all the information...i.e the info from table 1 and info from table 2 where the relation ship between id and other ids are stored.
i.e say client has id=6.This id has property,name,etc stored in table1.
This id can further be related to any number other of ids.It can be related 2,5,100,or may be even 10000s of other ids.This mapping between the original id and other ids..are stored in table2.
So given the id by the client , i would want to return property of the ids itself along with all the ids that it is related to .
I want to achieve this..... -

How to downgrade my iPhone iOS7 to iOS6 ?
Maybe reset your iPhone 4 to Factory Conditions? I'm not sure this will work and would probably ask an Apple Genius if that might work. It was shipped from the Factory with iOS ? ... maybe 4 or 5? Good question ... I suspect a lot of iPhone 4 users will want to return to iOS6.
Another solution is to bite the bullet and upgrade for $99 to an iPhone 5C. A little painful but much better in the long run.
