Re-Using Java Business Layer in Flex

I am new to flex and particulalry looking at this to use as front end for existing Web based Java Application as front end. We have comprehensive business layer written using POJOs and DAOs and want to reuse it. I will be using remote objects to call servr side code and return domain objects (models/POJO). As per my understanding to use the strict typed data such as objects of business classes i have to create ActionScript class and bind it with corrosponding Java class. This looks lots of code duplicaiton to me.
Can you please guide me if my understanding are wrong or i'm missing something. Is there better way to acheive the above?
Thanks in advance.

HTTPService can call HTML pages, so maybe Tapestry would work?
Have you considered using JSON to format the object data?
These lins describe using JSON and Flex:

Can't display a Tile Layer using JAVA API V2 (based on HTML5)

Hi Experts,
I am trying to display a tile layer using JAVA API V2 but i get the below error and nothing shows after that.
MAPVIEWER-05501: Map tile layer not found. Check map tile layer name and/or data source name.
Source: OM.layer.Tilelayer.getTileLayerConfig
*[mvdemo.demo_map]*
I tried with chrome and firefox browsers which supports HTML5 but same issue. Here is the html code i am using
<html>
<head>

</html>
Note: inside the body on load i use DIV Id = Map (i skipped that one line of code because it stops rest of the line from displaying in the thread)
However, I am successful in using the same tile Layer with JAVA API V1
Please share your thoughts as what could be the fix
Thanks
Nag

Nag,
inside the body on load i use DIV Id = Map (i skipped that one line of code because it stops rest of the line from displaying in the thread)please surround your code with [ c o d e ] [ / c o d e ] (without the spaces).
Secondly: this is probably more appropriate for the {forum:id=727} forum.

How to use Java objects in business rules 11g

I have made one business rule with two XML facts and then follow one doc to create the java facts.But I am unable to use the facts.

No Java Facts are created,but as I have mentioned XML input and output facts at the time of creation of business rules,so I am not able to use java fact in business rule.

Which business layer for ADF/JSF applications?

We are considering developing j2ee applications using ADF Framework ad JDeveloper. We have choosen to use ADF framework using ADF Faces as a view layer, JSF Controler.
Can someone give me a suggestion about which tecnology to use to build service layer?
Since we are java developers, is it better to use Toplink POJOs or is there some advantages using ADF BC.
Is there any tutorial or note thet can help us making this choice?
Thank you very much
Michele

The ADF Developer's Guide for Forms/4GL Developers and the corresponding end-to-end tutorial for the SRDemo sample using ADF Business Components should be on OTN by the end of this week. If you are interested in a pre-release, please email me at [email protected]
Thanks.
The ADF Developer's Guide for advanced J2EE Developers and the end-to-end tutorial using EJB/Toplink are already on OTN. Using these side by side, hopefully it will help you get an idea of which one feels like a better fit for your team's background, experience, and preferences for ways of working.

Create a new dimension in business layer from Data source: text file on the web

Hi,
I have a text data source which is published every few hours that is accessible from a certain URL. I follow the instruction given in this http://scn.sap.com/docs/DOC-43144 - where it shows in great detail how to create the connection, data foundation as well as business layer to create a universe for this type of data.
All is well - I can use this universe in my WEBI doc and display the data.
However, in order for me to merge the data from this universe with another universe, I need to create new dimension based on the data from the text file. The new dimension value is simply the first 4 characters of the Subject found in the text file. The "Subject" dimension is of variant type: varchar.
Following the guide mentioned earlier, the connection is using SAP BO OpenConnectivity driver. And this driver limits severely the SQL statement that I can use to extract a substring of another string. Here's the screenshot of the SQl expression that I can use with this driver
After hours of searching, I cannot find any other connection driver for a text file that's published on a certain URL. The BO OpenConnection driver is the best that I could find.
So here are my problems
1. one of my data source is a text file published on a web
2. the only connection I can create does not allow me to create new dimension in the universe to create an important column "subject ID"
3. I can create the column in webi as a variable. But when I do so, I cannot merge it with existing dimension (webi not allowing to merge these 2 types). And without the merge, the flat file universe with my database universe can't be combined.
I'm using WEBI Rich client version 4.1 SP3 Patch 1. Build 14.1.3.1300
Is there any other idea that you can suggest without requiring to change the extracted data?
Thanks.
With warm regards

Hi Bala,
Were you able to find out a solution for the problem with uploading values for a variable from a text file on the web? I am confronted with the same request from users.
Thanks,

BO 4.1 SP4 IDT - Not able to publish the Business layer onto the repository

Hi All,
We are facing issues while publishing the Universe onto the repository. Just to give a background of the issue, we are connecting to Oracle 9i database from BO 4.1 SP4 Information Design Tool. We have client tools installed on one VM server and BO enterprise server on the other VM . I have installed Oracle 11g client 32 bit on the client tools server and 64 bit on BO Enterprise server. I can create a session to the BO server from the IDT tool successfully I have even created a secured connection published on SAP BO server which means there are no port issues.
I create the data foundation and business layer on IDT. I have created a test one with only two simple tables and do an integrity check and it works fine. When I publish the Universe, after I click the Finish button, it just freezes and doesnt get anything back for a long time. After that period, the finish button gets enabled again and if I check on the server, Universe is not published.
Based on the KB 1586166 - How to enable tracing for BI4.x client applications I created two BO_Trace.ini file in the following directories:
C:\<user-dir>\.businessobjects\bimodeler_14\config
D:\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\conf
I was getting the trace files earlier as well but I just changed to see if something happens. I I have a hs_error_pid4198 file created on monday, but it seems to be a java environment error file. I am not sure if its related. The trace I see on the InformationDesignTool_ncs file is
trc file: "InformationDesignTool_ncs.trc", trc level: 1, release: "720"

Unable to create Business Layer on top of SAP BW OLAP Connection - BI 4.0

Friends,
Need an useful information, why can't we create a business layer on top of SAP BW OLAP connection which is built with BICS driver.
Today when i tried to create a business layer in IDT tool of BI 4.0 it didnt allow me to do so. Is it a s/w bug or am i following a wrong approach. I do know, we can create a .unx universe through relational connection. But i dont want that, please provide your input.
thanks,
Tilak

Hi,
this question has been asked many times before, so a search will reveal your answer.
as the warning told you when you tried the workflow in IDT - business layers aren't supported for Bics connections - i.e. you can't create a UNX ontop of Bex using BICS..
unfrotunately, it was a strategic product decision that seemingly can't be reversed/influenced, despite the inherent problems this causes.
There are lots of requests for this feature to be restored, on the Ideas Place here: https://cw.sdn.sap.com/cw/community/ideas/businessanalytics/sbosemanticlayer
Please search and Vote for one.

Creation of Business Layer

I am trying to create a Business Layer using the wizard. I have selected the user whose tables i want to load. But the list of schema Objects for this user that is seen in the wizard is very few. Is it because the EUL owner user which i have used to login to Discoverer administrator does not have select access on these tables?

Hi Russ,
Well, at it's simplest when a database session is created by Discoverer Admin or User editions then the database session must have the privileges to do the task that you want to perform. So when you connect to Discoverer Admin to add some tables to the EUL the session must have select access on those tables. If you have not connected as the EUL owner then it doesn't matter what privileges that the EUL owner has been granted, it is the user you are connected with that matters.
So in an Apps mode EUL I never grant any table access to the EUL owner. I think that opens up the Apps security unnecessarily. I always connect to Disco Admin as an Apps user (I usually create an Apps EUL Admin user for this purpose.) Then when you are connected as the Apps user your session is an APPS session so the session has access to all the APPS tables etc. and can therefore add tables to the EUL and grant privilege to other Apps users/responsibilities.
Therefore the process I use is:
1. Create your EUL_US Apps mode EUL
2. Create a EUL admin Apps user, EULADMIN in Applications
3. Connect as EUL_US and grant all EUL admin privileges to EULADMIN
4. Connect as EULADMIN and do all your EUL administration.
Hope that is clear,

Confused.. trying to stop a flash video using java

Hi, I am trying to put a video on a webpage that uses java to
hide it's visibility.
This layer has a video, and when a person clicks on a link
java hides the layer and it is supposed to stop the video from
playing. I know how to hide the layer, but I am new to flash and I
have not seen a way to use java to turn of the video.
Any ideas? How I can use a simple java function to turn the
video off?
Many thanks for any ideas to solve this.
Joe

I'm pretty sure that you mean Javascript and not Java. Have a
look at the ExternalInterface class. There are some examples in the
online help that demonstrate calling a function in a Flash movie
from Javascript in the HTML doc.

Java API for Adobe Flex(AIR and Browser)

Hello Community,
Sometime ago i started the project located at: : http://code.google.com/p/gwt4air/ , wich primary goal was to bring another approach on writing AIR application by providing a Java API for the AIR API. On top of that i added support for PDF and Excel generation using Java.
I m glad to announce that the project will now add support for the Flex Framework
I wrote a post about it on the main page.
The Idea behind it is to give Java Developers a more simple way to write Flex Application by leaveraing a swing like API.
I hope this project will be a good alternative to the MXML+ ActionScript approach and looking for people willing to join the project.
Regards,
Alain

Good question, I'd like to know this myself. 4.5 has a huge number of changes since 4.0.

Strange class error when using java

I've been attempting to use java.awt.robot to simulate a key press when a button is clicked however I'm getting a couple of errors that I can't figure out but I'm not so good when it comes to scripts. When the button "LetterButton" is pressed it should simulate a keypress, ideally to the desktop/operating sytem but the errors I'm getting are:-
1071: Syntax error: expected a definition keyword (such as function) after attribute public, not static.
1084: Syntax error: expecting rightbrace before leftbrace.
1131: Class must not be nested.
Here's the code:-
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplicationxmlns:mx="
http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import java.awt.Robot;
import java.awt.event.KeyEvent;
public class Main {
public static void main(String[] argv) throws Exception {
Robot robot =
new Robot();
robot.keyPress(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_A);
]]>
</mx:Script>
<mx:VBox x="359" y="262" horizontalCenter="0" verticalCenter="0">
<mx:Button id="LetterButton" label="Button" click=""/>
<mx:TextInput id="txt"/>
</mx:VBox></mx:WindowedApplication>

Sounds tricky. I may ask them to look for an alternative way of doing it as Java really isn't my thing, I'm merely just a flex beginner at the moment.
The reason I've been looking for this is that my app will be installed on a digital tv that also has a system connected to it using a Linux operating system so the user can switch between watching digital tv and the application seamlessly and at the moment a Linux professional who I'm working with has the Digital TV bound to the F12 key which is bound to a handheld remote control (being a tv there is no keyboard, just an 'air mouse' and the remote control).
So my client and my Linux guy have asked me to come up with a way of getting the app to communicate with the desktop/operating system. I have seen flex apps in the past where a user can drag and drop videos on their desktop into an air application from which they will be played so I thought it would be possible to interact with the exteral OS/Desktop from within an AIR app by using just flex but it doesn't seem so easy through my research.
Thanks for your help though.

In Struts is it possible to use java code in jsp?

in Struts Tag Program in jsp pages is it efficient to use java code? Please explain?

No issues.. you can use java code... in jsp struts

SJYou can use Java code as scriptlets in any JSP, but that doesn't mean there are no issues.
I would say it's a bad idea for the following reasons:
(1) Scriptlet code is difficult to read when mingled with HTML
(2) You can't unit test scriptlet code
(3) It increases the chance that business logic will leak into pages where it doesn't belong.
Better to use a well-proven tag library like JSTL or the Struts taglibs and keep all scriptlets out of your JSPs.
