Where i shall write html code in jdeveloper

Hello,
please tell me where i can write html code in jdeveloper.
Thanks

Hi catalina,
Html tags should not be used directly inside ADF faces pages which may lead to some undesirable results instead you can use ADF Faces tags itself using which you can do what ever you wanted to do with html tags.
If you still need to use html tags, you can use ADF Faces html tags.

Can i write java code in JavaScript function

I want to call JavaBeans within JavaScript function. Can I do it?
I have a button in JSP . When the button be clicked,the data be inputted will be checked by JavaScript function. If check is ok, then call a Bean's function to write the data to database.
Please Help!

well indeed u can write java code in javascript functions. But probably it will not work the way u want it to.
when u say that u click a button, it means that some client side action is performed. Now if u wud require a java bean to be called then it means that the server needs to be contacted for the same, and if that has to be done, necessarily the form needs to be submitted.
U can populate values from a java bean and then the same can be made available to a javascript variable / function when the page is loaded rather than, when the button is clicked.
What u can do is on click of button u can process [display / calulate..etc ] the information which has already been got by the java bean.

Where to Place Custom Java Code

We are planning on adding customized Java code to Identity Manager 8; XPRESS will be used to call the customized Java code.
Questions:
1) Where does this customised code reside in the Java Application Server (Glassfish)?
2) Does the customized Java code have to be packaged in a JAR file?
Many thanks for your help.

You would deploy custom Java code along with the IDM war/ear file. Classes go in the WEB-INF/classes/ folder, JARs in WEB-INF/lib/ and that is application server independant.
Class files or JARs? Do you have any build process for your IDM, like the custom build environment CBE, then the source files might end up as class files; if you are using a seperate build environment for those custom classes, then packaging them in a JAR would be the way to go.
Generally speaking, using a JAR for your custom code is neater; whether a class in classes/com/foo/bar/Foo.class or in lib/myfoobars.jar takes precedence over the other is up to the class loader and depending on your application server and its settings, the behavior might vary - so be careful about mixing use of those locations.

Where do I write the code for customer exit variable?

Hi Gurus,
Can anyone tell me where and the procedure that I have to follow to get to the include ZXRSRU01 where I can write customer exit variable code.
I know its written in ZXRSRU01, but in my system it seems like its not active or does not exist. How do I get to start working in this include for customer exit variables?
Any help is appreciated. Thank you.

Where do you write your code?

I've just started to learn Flex. One question I have is where
you put the ActionScript code?
I know i can put it in several locations (e.g. inline, within
a script-tag, in actionscript-files, in actionscript classes) but
what's the best way to go?
Up until now I haven't done so much coding, so I have just
written the code inside a <mx:Script>-tag in my MXML-file.
I'm starting to realize though that having both MXML and
ActionScript in the same file is a bit inconvinient when the amount
of code increases.
Since I come from the dark side ;) (Microsoft), I'm used to
having to files for each page/component; one with the "UI code"
(MXML in this case) and one with the logic (AS in this case). I
like that model, so I tried to do something similiar in Flex. My
MXML-file looks like this:
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" applicationComplete="MainCode()">
<mx:Script source="MainCode.as" />

</mx:Application>
Then I create the MainCode.as and give it a function called
MainCode(). That way, I now have the code in a separate file/class,
and themethod becomes the starting point of the execution. Kind of
like the "document class" in Flash.
First, this seemed like a good solution to me BUT soon I
realized it has a big flaw. Since the class is not hard linked to
the MXML, I will not get any intellisense/codehints about the
components/controls I use in the MXML (at least I don't in
FlashDevelop).
So, how do you do it? Is there a way that is considered "best
practice"?

It's better to do one of two things:
1) Get everything pretty much complete and then only pull it
out to an as
file when you're done. That way you get code hinting all the
way up to the
time that you pull out the code. Note that this will _not_ be
a class and
should not have a constructor, etc. or be named the same
thing as any MXML
file in your project.
2) Only pull out things that can truly stand alone, and make
them separate
class. You need to look up these terms on google or your
favorite search
engine "loosely coupled Flex components."
Also note that you can use more than one script tag, and
these will be
visible in outline view. Unfortunately you can't give them
ID's. Also,
using bookmarks can help with managing files with both MXML
and AS.

How can I write java code in web dynpro to show KM content document?

I need someone to write a Java Script for my Adobe Acrobat form. I do not know how to write Java Code

I have never worked with Java coding and am in need of assistance for an acrobat form I am working on.
     - I have a form with a field identifier called BACompnayName (this is the field where they would enter their company name).
     - I then have a form field with two radials that says "Is the shipping address the same as the business Address" - "Yes" and "No" (the form identified for this field is SASame.
What I am trying to accomplish:
     - If they click yes, I would like the form to fill in the information found in BACompanyName otherwise, leave it blank to be filled out by the person filling out the form.
I appreciate any help.
Thanks,
Brett

Student in need of HELP!Best application for writting java Code?

I've been working on two different systems and need to be able to work on both..On one system the SDK is installed on a linux machine on another on a windows machine...unfortunately i cant open the linux created files on my windows machine although i can compile ad run them! What application would allow me to work on both systems wothout creating problems?

Hi,
I am a bit confused by this question. My colleagues here use Windows to create their files and I use a Linux machine. I have never encountered a problem as described here. Its a company policy here for everyone to save files in UNIX format, so I can readily open and edit those files created in Windows on my Linux box with NetBeans or EMACS I use. Sometimes when my colleagues forget to save their files in UNIX format, I have to apply dos2unix to mend those files, but still that isnt too teadious at all.
Try opening the files you created in Windows with any text editor that you have available in Linux - vi, emacs, gEdit whatever. And please tell here what problems, if any you encountered, in actually editing them again.
Correct me if I have misunderstood your question.
hth,

After reviewing http://docs.oracle.com/cd/E26098_01/web.1112/e16182.pdf it seemed like the application module was the preferred spot (although many of the examples in the pdf are in main methods). After coding a while though, I noticed that there were quite a few libraries imported, and wondered whether this would impact performance.
I reviewed postings on the forum, especially Re: Access service method (client interface) programmatically . This link mentions accessing code from a backing bean -- and the gist of the recommendations seems to be to use the data control to drag it to the JSF, or use the bindings to access code.
My interest lies in where to put java code in the first place; In the View Object, Entity Object, and Am object, backing bean.....other?
I can outline several best guesses about where to put code and the pros and cons:
1. In the application module
Pros: Centralized location for code makes development and support more simple as there are not multiple access points. Much like a data control centralizes services, the application module can act as a conduit for different pieces of code you have in objects in your model.
Cons: Everything in one place means the application module becomes bloated. I am not sure how memory works in java -- if the app module has tons of different libraries are they all called when even a simple query re-execute method is called? Memory hog?
2. Write code in the objects it affects. If you are writing code that accesses a view object, write it in a view object. Then make it visible to the client.
pros: The code is accessed via fewer conduits (for example, I would expect that if you call the application module from a JSF backing bean, then the application module calls the view object, you have three different pieces of code --
conts: The code gets spread out, harder to locate etc.
I would greatly appreciate your thoughts on the matter.
Regards,
Stuart

First point here is when you say "where to put the java code" and you're referring to ADF BC, the point is you put "business logic java code" in the ADF Business Components. It's fine of course to have Java code in the ViewController layer that deals with the UI layer. Just don't put business logic in the UI layer, and don't put UI logic in the model layer. In your 2 examples you seem to be considering the ADF BC layer only, so I'll assume you mean business logic java code only.
Meanwhile I'm not keen on the term best practice as people follow best practices without thinking, typically best practices come with conditions and people forget to apply them. Luckily you're not doing that here as you've thought through the pros and cons of each (nice work).
Anyway, back on topic and off my soap box, as for where to put your code, my thoughts:
1) If you only have 1 or 2 methods put it in the AppModuleImpl
2) If you have hundreds of methods, or there's a chance #1 above will morph into #2, split the code up between the AppModuleImpl, ViewImpl and ViewRowImpls. Why? Because your AM will become overloaded with hundreds of methods making it unreadable. Instead put the code where it should logically go. Methods that work on a specific VO row go into the associated ViewRowImpl, methods that work across rows in a VO go into the ViewImpl, and methods that work across VOs in the associated AppModuleImpl.
To be honest which you ever option you choose, one thing I do recommend as a best practice is be consistent and document the standard so your other programmers know.
Btw there isn't an issue about loading lots of libraries/imports into a class, it has no runtime cost. However if your methods require lots of class variables, then yes this will have a memory cost.
On a side note if you're interested in more ideas around how to build ADF apps correctly think about joining the "ADF EMG", a free online forum which discusses ADF architecture, best practices (cough), deployment architectures and more.

Fill a pdf form with data using Java code

Hi,
Modern formats of Acrobat ".pdf" files allows to define form fields.
I have a datasource, let's say in a database.
I want to fill my ".pdf" with my database-stored data automatically, and want to write Java code for that.
1. What is the best way to achieve this ?
2. Is it necessary to install Acrobat Distiller server and if so what web services should I invoke ? Where is the doc ?
3. Are there efficient Java libraries to do so ?
Thank you for helping... As ever, this is kind of an emergency case
Have a good day.
Phil

Take a look at the FDF Toolkit for Java:
http://www.adobe.com/devnet/acrobat/fdftoolkit.html
That will allow you to, through Java, construct an FDF that contains all your form data. You then add a reference to your "template" PDF file in the FDF as well and send the FDF to the client. Acrobat will open the FDF, see the reference to the PDF, open the PDF and then merge any data contained in the FDF with the PDF.

Can i write java in JSF

i need to write java code in JSF. can i use scriptlet <%%> as i use in JSP? if not than How can i write?
thanks..

The short answer is no.
The medium answer is yes you can, no you may not.
The long answer is that there is always a better way to do it than writing code on the page. Its very tempting, it can be fast, it may even work. Either you or whoever comes after you will regret the decision. The problem is you'll probably end up not knowing what decisions your code is making and where they are being made. Force yourself to do it the "right" way and coming back to your pages to make changes will be a much more pleasant task.
