How can i understand nested application module?

Is there inherit relation between root application module and child application module?
jiayu
thanks

Hi,
no, they are not inheriting from each other but share the same transactional context. Nested AM are also loaded lazily, which means you minimize the footprint of your app.

Nested Application Module

I have this problem, and I wish I can find a solution.
I have two application module, am1 and am2, am2 is nested in am1, and I'm using <jbo:ApplicationModule> tag to open a connection for the application module.
I have this case, I want to access page that insert into a table but this insertion should not be committed until another operation is committed, and these two operation occurred on two different views in the 2 application module, so I want to know how can I get the application module am2 using <jbo:ApplicationModule> tag, and making it using the transaction context of application module am1.

Omar,
there is a getRootApplicationModule()method on the ApplicationModuleImpl class, did you try this ?

Nested application module use own connection

Hi everyone,
I'm trying to figure out how to let a nested application module use it's own connection instead of it's parent.
Any suggestions?
We're using Jdeveloper 10.1.3.3.0.
Regards

Hi,
The issue is not about the data, but about the database connection. The idea is to have a general BC library (with iits Application Modules and View Objects), using its own database schema, and have that one imported in other applications, with other database schemas.
We have to use these imported BC's in the application AM, because that's the way JHeadstart works. This will result in a table not found exception, because the imported VO's are in another schema.
We were hoping that we could nest an imported Application Module and that it uses its own connection to its own database schema, but unfortuantely that does not seem possible since nested application modules inherit the connection of the parent (root) application module.
Or is there perhaps a way to achieve this; i.e. have a nested application module using its own database connection and not inherit this from its parent?
Ciao

Jclient Binding to nested application module

we use a test case of
Applications
ParrentAM & NestedAM
Forms
ParrentForm & NestedForm
We added a reference to the NestedAM datacontrol in the ParrentDatabindings.cpx
When the ParrentForm attempts to set the bindingcontext in the NestedForm we recieve a null pointer exception.
Can anyone provide some insite or an example for binding to a nested application module?
thanks.

Robert,
what do you mean with "Nested Form", is it a JClient panel that is contained in another JClient panel ?
Which JDeveloper release are you working with? Can you provide me a step by step instruction on how to reproduce your testcase in JClient (assume that I have a Business Component Model that has a MasterApp and a nested NestedApp module, both based on the Scott schema).
thanks for your help

How do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
    setAttributeInternal(REPLACEMENTPRICE, value);
    AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
    Key key = new Key(new Object[]
        { getPartNumber() });
    am.recordPartHistory(key); // AppModuleImpl method which records pricing history
    am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

Nested Application Module Performance

What are the implications of nesting application modules? I am nesting them in such a way that they are defined at design-time and used by calling findApplicationModule(String) on the root ApplicationModule. Could there be any significant overhead accessing one nested app mod in this way as opposed to going to the desired app mod directly? Or is there anything else to watch out for with this type of design? I haven't had any trouble so far but my project is not too large yet.

For example, I have three ApplicationModule objects.
RootModule, Module1, and Module2. By nesting Module1
and Module2 under RootModule, I can use either once I
have an instance of RootModule by calling
findApplicationModule(String name). This is useful
when I want to do things inside both Module1 and
Module2 and still use the same connection and
transaction context.
If I only want something out of Module1 during a
request, would it be advantageous to ONLY create
Module1 directly and bypass my RootModule?
Meaning this:mod1Am =
Configuration.createRootApplicationModule("Module1","M
dule1Config");
mod1Am.myCustomOperation();As opposed to
this:rootAm =
Configuration.createRootApplicationModule("RootModule"
"RootConfig");
mod1Am = rootAm.findApplicationModule("Module1");
mod1Am.myCustomOperation();
Nick:
There are advantages to creating Module1 directly. It would be that you don't create unnecessary objects (in your case, you would avoid unnecessary creation of Module2").
However, I would make the following side comment: from your message, it sounds like you would create an AM for every request and remove it at the end. Did you consider using AppModule pool? AM pool would be better than create-remove because AM pool can keep around a number of root AM instances and manage resources for you. This way, you don't have to create any AM for each request. AM pool is also able to support stateful operations with excellent scalability.
Thanks.

Nested Application Module State

As I understand it Application Modules (AM) that are nested inherit the parent 'Transaction'. My question is do they inherit the Stateful/Stateless behaviour from the parent ?

yes it inherits' the complete definition.
including release_mode, which is the parameter i assume, that you mean.

I have installed Adobe packages and cannot find the Acrobat extension folder please advise how can I get these applications to load onto my computer?

I have installed Adobe Creative Cloud for teams CC Packages which says that Acrobat XI Pro is installed. Your support page says it does not install Acrobat and I have to look in the Extensions folder for an MSI file. I have run a number of searches and cannot find the Acrobat extension folder please advise how can I get these applications to load onto my computer?
Also I now administer the teams and have accepted the invitation to I received to be a team member and download the apps. The admin page shows that I have been sent an invitation but does not show my account as "ACtive" unlike my other team members. I tried to use the link in the invite to accept it become active but the link displayed an error saying I had already accepted the invite... why is no account not active?
Finally what other product downloads in Creative Cloud do not actually download as part of the Creative cloud Packager for downloading the apps? e.g. acrobat and what else?

My apologies Eadeszoo I believe our support agents are unavailable on January 1.
Are you able to copy the contents of the DVD to your computer? Are you receiving any particular error messages when you are trying to install? Finally which operating system are you using?

How can I use the print module to print different size images on one large "canvas"?

How can I use the print module to print different size images on one large "canvas"? An example would be in Photoshop, go to file>new, and create the size paper I want, and move images of different sizes onto it.
I was thinking the print module would do this automatically for me.

You can't, at present. It's been a requested feature, so we'll see if it shows up in a future version, but it's not there at present.

It sounds like you essentially have a new computer and unless you restored from a backup your iTunes library would be empty. You can transfer your iTunes purchases from your iPod to the computer by:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
SInce you changed syncing computers. after you move the stuff you need to restore the iPod to factory defaults and sync the stuff back to your iPod. If you had the iPod backup file you could restore from backup.
If you have non-iTunes pruchases you can copy them to your computer by using one of the third-party programs discussed in this previous discussion:
