ADF-Newbie.How can I create a many-to-many row from an action method?

Hi all,
First of all, this is my scenario:
- JDeveloper 10.1.3.0.4
- My application is running ADF + Faces + Toplink + EJB Facade
- My database model includes some many-to-many relationships and some one-to-may relationships.
I have developed several ADF pages displaying some CRUD operations over my master tables and my master-detail tables without any problem.
I am now trying to implement some CRUDs over my many-to-many relationship tables.
Lets call the tables involved as master1, master2, and relationship (the many-to-many table)
Because usability reasons, my user wants me to implement an interface where he can:
-Select a row from the master1 table
-Select a row from the master2 table
-Click a button called "Create relationship"
I need to implement the code inside the action button to add my new record on the relationship table, and honestly, I have not found any clue.
Please, give me some directions to solve my problem.
Thank you in advance for your help...

The key here is to work with the intersection table for your MtM relationship.
The way I do it, is to have the user view Master Table I, and click on the add Relationship button, this button is a link to a add form for the Intersection Table. On the Add form, the MasterTable 1 Id is already filled in and I hide it. I then setup MasterTable 2 as an LOV on the page. The used selects the item from the LOV and clicks on the commit button. I refresh my many-to-many view and all is grand.
Using ADF/JSF, I have made it even nicer by turning the add relationship page into a dialog page, that way the user can see the previous page while adding the new relationship.

How can I create a master PDX that pulls from multiple other PDXs?

I process aviation maintenance manuals, with the individual manuals having their own PDX. How can I create a master PDX that pulls from the individual PDXs?
I have access to myriad versions of Windows and Acrobat so there's that...

I’ve got 100s of manuals each with their own PDX. I’ve been asked to create a master PDX that in effect combines all of the individual PDXs into a single (cross-manufacturer, cross-fleet, cross-manual-type) searchable PDX that can be easily updated.

How can mass create batch classification for many material batches? ?

Hi Experts,
In our system , there are so many material batches which have not been classified，see by
BMBC Tcode.
That means these batches has no values in the batch class. I know we can create
classification for these batches with MSC2N Tcode.
But there are so many batches which have not been classified,more then 2000.
It is not possible to create classification for every batch with with MSC2N once a time.
So how can I create batch classification for so many batches once a time?
How can I mass create batch classification for so many batches??
Thanks for any reply!

Hi,
Please be aware that SAP does not support the use of batch
input in the classification system. SAP recommends you use BAPI's for
example in your case BAPI BAPI_OBJCL_CREATE and BAPI_OBJCL_CHANGE
would be able to help. For more information, please have a look at the
note: 943559 - Point 2 and 13. Point 13 references the note 1083986.
I hope this helps!.

ADF & JSF : how can I create a clickable image

Hi,
How can I create a clickable object with an image property and have an action, I want to use it instead of a command button.
thanks,
Ahmad Esbita

Hi Ahmad
One way is to drop an objectImage tag inside a commandLink tag without a text attribute as follows:
<af:commandLink actionListener="#{backingBean.someMethod}">
<af:objectImage source="/someimage.gif"/>
</af:commandLink>The image is clickable raising the actionListener event.
Hope this helps.

How can I create a array with all files from a directory

How can I create a array of files or varchar with all files from a directory?

I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

How can I create a diagram where equal data from different cells will be added to one sector?

Hi,
I'm a new Mac user, so I have a lot of problems and questions every day. Moving to Mac from PC is not an easy thing)
Here is my problem:
I need to create a few diagrams for my science work, but can't correct one mistake. Every time one data from one cell from the table takes its own place in the diagram. But I need to ceparate equal data to show it is one section.
An example:
Sex
Age
Female
18
Female
18
Female
18
Female
25
Female
30
We need to create a diagram to show that we have
60% - 18 years
20% - 25 years
20% - 30 years
But Numbers doesn't show it that way. Here how it does:
So please help me. How can I do that?

Hi ProCauda,
Some example data of people and their age:
The COUNTIF function will give the number of people of each age.
In another table, B2 contains this formula (and Fill Down to the bottom of B)
=COUNTIF(Table 1::B,"="&A2)
In this example, 3 people are 18 years old, 0 people are 19 years old, and so on. Use this table to calculate each age as the % of the total, then use that as the data for your diagram (graph, chart).

Ian.

How can i create a grid with summary row

Hello Professionals,
I'm wondering how could i create a grid like the grid below, i want to create a grid with summary row,
i have tried to create it using collapsing but it didn't work as required.
Any suggestions?, i want to know just the starting point so i can make deep investigations.
Thanks in Advance,

Hi Karem,
this can be achieved by just assigning a datatable containing the data plus some formatting of grid. Meaning there is no feature for that.
The datatable can be filled manually or by sql query. Then you have to attach some events for updating the values ( validate after for gid item ).
A small example for a sql query showing last month quotations and orders with summary :
select 1 as Sort,cast(DocNum as varchar) as DocNum,DocTotal,convert(varchar, DocDate,104) from OQUT where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
Select 2 as Sort,'Summary ( Quotation ) : ',sum(DocTotal), convert(varchar, DATEADD(month, -1, GETDATE()),104)+' - '+convert(varchar, GETDATE(),104) from OQUT where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
select 3 as Sort,cast(DocNum as varchar) as DocNum,DocTotal,convert(varchar, DocDate,104) from ORDR where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
UNION ALL
Select 4 as Sort,'Summary ( Order ) : ',sum(DocTotal), convert(varchar, DATEADD(month, -1, GETDATE()),104)+' - '+convert(varchar, GETDATE(),104) from ORDR where DocDate between DATEADD(month, -1, GETDATE()) AND GETDATE()
ORDER by Sort

How can I create a function of sound volue from time using AudioQueueBufferRef??

I have a question how can I analyze class AudioQueueBufferRef, for creating a function of sound volue from time?? Here is what I get . there is AudioQueueBufferRef fillBuf = audioQueueBuffer[fillBufferIndex]; volume height is 2000 elements from SInt16* coreAudioBuffer = (SInt16*)fillBuf->mAudioData. so function looks like H(t*i)=coreAudioBuffer[i] where t = 1/sampleRate = 1/22050 but here is a problem. my program gets sound and uses a class AudioStreamer for this. AudioStreamer has 3000 lines when I play music from Free Internet Radio - SHOUTcast Radio - Thousands of Free Online Radio Stations. internet radio - my problem is as follows either I dont know where 85 % of sound information is or I dont know how I can analyze class AudioQueueBufferRef
Here is the code where I analyze Buffer.
{@synchronized(self)
if ([self isFinishing] || stream == 0)
return;
inuse[fillBufferIndex] = true; // set in use flag
buffersUsed++;
// enqueue buffer
AudioQueueBufferRef fillBuf = audioQueueBuffer[fillBufferIndex];
fillBuf->mAudioDataByteSize = bytesFilled;
// ======>in this place I analyze Buffer
if (packetsFilled)
err = AudioQueueEnqueueBuffer(audioQueue, fillBuf, packetsFilled, packetDescs);
else
err = AudioQueueEnqueueBuffer(audioQueue, fillBuf, 0, NULL);
when bitRate = 24 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 2000 double sampleRate=asbd.mSampleRate == 22050 numberOfChannels = asbd.mChannelsPerFrame == 1 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.1 number of buffers per second float numBuffersInOneSeconds == 1,5 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.15 so it is 15 % of all information
as a result If buffer comes at 0.0 seconds he lasts up to 0.1 seconds.farther in my function there is no volume. second buffer comes in 0.7 seconds and lasts up to 0.8 seconds. but in reality the sound doesnt breaks. Maybe I'm doing something wrong .please tell me.
just for comparison
when bitRate = 32 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 2000 double sampleRate=asbd.mSampleRate == 22050 numberOfChannels = asbd.mChannelsPerFrame == 1 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.1 number of buffers per second float numBuffersInOneSeconds == 2 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.2 so it is 20 % of all information
when bitRate = 32 buffer has the following options int size=(fillBuf->mAudioDataByteSize) == 1660 double sampleRate=asbd.mSampleRate == 44100 numberOfChannels = asbd.mChannelsPerFrame == 2 it turns out that duration of play buffer float bufferTime =(size/numberOfChannels)/sampleRate == 0.02 number of buffers per second float numBuffersInOneSeconds == 10 duration of play all buffers per one second numBuffersInOneSeconds * time == 0.2 so it is 20 % of all information

You cannot write custom commands for expressions.
That being said, there are a couple of options:
Create a subsequence with a single step. Use a parameter of the sequence as "function parameter".
Create a custom step type including a substep module which implements the function. Add an edit substep to enable the user of the steptype to gracefully change the parameter.
Store the variable parameter in a local/file global variable and modify the value in each step. This will, at least, keep the "function" the same for every step.

How can I create and design a page UI from blank page in jdev10g?

Hi.
How can I implement a page from scratch page?
I can create a master-detail page as the OBE site.
But I'm not sure how to create page using component pallets, instead drag data-control model to page.
It means I should design UI with component pallets,
How can I do?
Thanks.
Edited by: user10615931 on 2009-8-18 上午4:13

Thanks.
It is helpful to me.
What I want to do is use component pallets and add action to the component for creating a page instead using executeWithParam operation and drag view object from datacontrol to create page.
How can I do?
Thanks

How can I influence the JAX-RPC response message from a void method

Hello,
I used WSDL2Java to create a web service. This service seems to work but the xsi:type="somename" attributes are not included in the response. I want to get them in. Or, otherwise, I want the push webservice just to send an acknowledge message. Because, our client that's pushing the webservice message to us gets error messages.
But, while the webservice is a push service I don't know how to influence the returning soap envelope. This is the webservice method I mean:
public void putDatex2Data(eu.datex2.schema._1_0._1_0.holders.D2LogicalModelHolder body) throws java.rmi.RemoteException {
//the code
Furthermore, has someone good examples of implementations that help to get the real incoming XML message data in a easy way.
Thanks.

No, that's not a feature of the phone.

How can I get the variable with the value from Thread Run method?

We want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that scope of the variable gets lost resulting to null value in the called method/class..
How can I get the variable with the value?
This is sample code:
public class SampleSynchronisation
     public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run method "+sathr.x);
// I should get Inside the run method::: But I get only Inside
class sampleThread extends Thread
     public String x="Inside";
     public void run()
          x+="the run method";
NB: if i write the variable in to a file I am able to read it from external method. This I dont want to do

We want to access a variable from the run method of a
Thread externally in a class or in a method. I presume you mean a member variable of the thread class and not a local variable inside the run() method.
Even
though I make the variable as public /public static, I
could get the value till the end of the run method
only. After that scope of the variable gets lost
resulting to null value in the called method/class..
I find it easier to implement the Runnable interface rather than extending a thread. This allows your class to extend another class (ie if you extend thread you can't extend something else, but if you implement Runnable you have the ability to inherit from something). Here's how I would write it:
public class SampleSynchronisation
public static void main(String[] args)
    SampleSynchronisation app = new SampleSynchronisation();
public SampleSynchronisation()
    MyRunnable runner = new MyRunnable();
    new Thread(runner).start();
    // yield this thread so other thread gets a chance to start
    Thread.yield();
    System.out.println("runner's X = " + runner.getX());
class MyRunnable implements Runnable
    String X = null;
    // this method called from the controlling thread
    public synchronized String getX()
      return X;
    public void run()
      System.out.println("Inside MyRunnable");
      X = "MyRunnable's data";
} // end class MyRunnable
} // end class SampleSynchronisation>
public class SampleSynchronisation
public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run
method "+sathr.x);
// I should get Inside the run method::: But I get
only Inside
class sampleThread extends Thread
public String x="Inside";
public void run()
x+="the run method";
NB: if i write the variable in to a file I am able to
read it from external method. This I dont want to do

How can I create a camera profile in LR4 from my camera

I have a 5d mark 2, and I created a custom camera profile that is ideal for me, however when I shoot raw it only gives me the adobe, and camera standards etc. Is there a way that I can take my user setting on my 5d and transfer it into lightroom??

The camera profiles are only applied to the in-camera JPGs, never to the Raw files.
This is not only so for your Canon but for every camera that shoots Raw.
For creating a camera profile in Lr, see here:

How can I create a ringtone using a song from my itunes library?

I have installed a number of ringtone apps for my iphone to create a special ringtone. I have followed all the steps adding the tune to my itune library, but am unable to complete the final step of moving the tune from the library to 'tone' and then syncing the tune to my iphone as a ringtone. Any suggestions would be appreciated.

In iTunes pref>General - is the Tones option enabled?
When you plug in the Device - from the DEvies window go to the Tones tab at the top and select the Tones that you want to laod on the iPhone.
