What is the difference observerables /actions/events ?

I dont know if this is the right place to ask this but what is the difference between these three things. I understand the basics of actions and actionlisteners but what is the differences between these three objects? It seems like you could use any one of the three combinations to get the job done so what is the difference and what should be used when?
Observer with Observables
Action with ActionListener
Event with EventListener
Can some one explain this. I am sure its been asked before but I spent all day searching and still dont understand the difference.
Thanks

Observer & observerables are derived from the classical solutions for Action/event handlers in the software paradigm. There's nothing wrong that to manage a UseCase trigger, you use the Observer & observerables patterns inherently.

What is the difference between Action & Workflow?

hi,
What is the difference between Action & Workflow?
regards,
babu

Hi,
Actions
Actions are important for maintaining and improving business relationships. You can schedule and start predefined processes with the Actions component by means of user-definable conditions from transaction and marketing objects.
You can tailor the type and time of actions to the requirements of your customers and the processes in your company. This component enables you to match your service, sales and distribution management, and your campaign management even more closely to customer needs, and, simultaneously, to automate them
In simple words Actions are automatic actions that are configured to occur in business transactions (activity, sales order, quotation etc.) as a result of particular condition like change of status to let us say "in process" from "open".
Workflow:
The automation of a business process, in whole or part, during which documents, information or tasks are passed from one participant* to another for action, according to a set of procedural rules.
*participant = resource (human or machine)
SAP Business Workflow is the R/3 tool for handling the process automation within R/3 or between R/3 systems and other systems involved in the business process. It is flexible enough to handle ad hoc processes such as the circulation of an electronic document. It is robust enough to handle mission critical process in the production system such as the creation of a material master.
The different R/3 applications supply standard workflows for the commonly occurring processes. Once these workflow templates are activated, they are ready for immediate use. A complete set of workflow tools, including the workflow editor and workflow generation wizard, are provided to enhance these standard workflows or create new workflows. These tools are complemented with transactions for monitoring, tracking and the statistical analysis of the processes.
Because the business process often does not step at the R/3 boundary, various interfaces and third party tools are available for extending the process across systems.

What is the difference between action and workflow? How do I decide that I need an action in a transaction and not a workflow and vice versa?

Dear Experts,
I have few doubts and request your expert inputs to clarify my doubts.
What is the difference between action and workflow? How do I decide that I need an action in a transaction and not a workflow and vice versa?
Your earliest response is highly appreciated.
Thanks,
SMTP

Hi SMTP,
First of all, as I mentioned action is nothing but an executable work item which is designed in the workflow itself. In other words, Workflow is like your OOPS class. At run time, workflow instances are created just like objects of classes. Now, the steps designed in the workflow are called TASKS and the instances of tasks are called WORKITEMS. Now, the work items where any user action is required are called executable work items. ANd the work items where no user action is required (for example, sending an email in background) are called non-executable work items.
Whether to go with development of workflow or not depends upon your business scenario. If your requirement is only to send an email and you find any BAdi or exit where in you can write your logic then there is no need of creating a workflow. If there is a defined business process with defined users and time lines, then you can go with the development of workflows.
Rest, the below link will help you in understanding basic concepts of workflow :

What's the difference between Action Objects and ActionListeners

Hello,
in the Introduction to JSF two ways handling action are demonstrated. One way is "Combining Component Data and Action Object" the other way is "Handling Events."
What's the difference? When do I use this or that way?
The one thing I understand is when using "Combining Component Data and Action Objects" I use the default ActionListener and I may directly access the input values.
TIA,
Juergen

Hi Juergen,
The bottomline is 'not much', only in the details to these two approaches differ.
The ActionListener object will have events broadcast to it for a particular object by the event mechanism in JSF. You can add one to a specific component via the f:action_listener tag. This will have your listener getting events during specific points in the request processing lifecycle (you specify via your return value for getPhaseId).
The Action class that an actionRef reference refers to an Action that will be invoked during the invoke application phase. (see pg 71).
I would recommend using actionRefs and Action objects wherever possible and going to ActionListeners only when you need notifications during a specific phase of the request/response cycle.
Hope this helps,

What's the difference between splitting events and creating an event?

With photos selected in an event, "splitting" the event and "creating a new event" appear to do the same thing. Is there any difference? In either case, a new event is created with the selected photos taken out of the original event.
doug

Doug:
Auto split will split up the event into events based on the date requirement that's been set for events, i.e. 1 day per ever, 1 week ,etc. It's automatic. Whereas creating a new event you determine which photos go into that event.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

In Request type, what is the difference between action 'Change user' and 'Assign object'

Dear All,
I have used only 'Assign Object' for my 'Change User' request type. But the standard request type has 'Change user'. So, could you suggest , what additional purpose does Change Object serve
Regards
Plaban

HI Plaban
not sure if you answered your own question here?
Change User - by itself would allow update of address data, user parameters, defaults, etc
Assign Object - as you mentioned roles and profiles.
However, if assigning, I think you need to have both actions: change and assign
I recall (ages ago) that change was only the user details and not the role or profiles. As a result, there were a few threads where people had to update the action for the request type of provisioning would not occur.
This is something you could test

13.3-in, LED, HD displays 581177-001 and 580664-001 - what is the difference?

Hello,
I have just upgraded my HP pavilion 1020er from lowest CPU (AMD Athlon™ Neo Processor MV-40 (1.6-GHz, 512K L2 cache), UMA, 581171-001) to the highes one (Intel Core2Duo Processor (2.26-GHz, 1066-MHz FSB, 6MB L2 cache), discrete 580663-001).
The LED connector fit perfectly but thescreen shows nothing.
The fan is on, the power button switches it on and off but neither single action on the screen no sound. I tried to connect the external LCD - no result, though I'm not completely sure I managed to switch to VGA output.
So my questions are:
1. what is the difference in part numbers 581177-001 and 580664-001? Specifically what does MA stand for in "13.3-in, LED, HD BrightView (1366x768) MA (AMD systems)"?
2. Do I need to reinstall Windows since I upgraded from AMD to Intel?
3. Any ideas on possible reason are very much welcome.
Thank you.

Hi @PadliQ ,
Thank you for your post, I will do my best to help!
I see you upgraded the CPU on your notebook from AMD to an Intel.
Here is the HP Pavilion dv5 Entertainment PC Maintenance and Service Guide. I did not notice the part numbers you listed, but the processor is a supported one ( Chapter 3 page 20).
I would try this. Go to the bios screen and restore the defaults. This will cause it to scan and pickup any hardware changes you have made.
If you boot into safe mode does the display work?
I believe the MA in the description of the display stand for Matte finish as opposed to a bright finish. ( The bright finish has a more reflective quality and can make displays hard to read in brightly lit conditions.
If you still have an issue I suggest contacting HP support for assistance.

Buffer busy waits occur when an Oracle session needs to access a block in the buffer cache, but cannot because the buffer copy of the data block is locked. This buffer busy wait condition can happen for either of the following reasons:
* The block is being read into the buffer by another session, so the waiting session must wait for the block read to complete. If the OP is running 10g, that would be recorded as "read by other session" not "buffer busy waits" - and unfortunately he didn't tell us the version.
* Another session has the buffer block locked in a mode that is incompatible with the waiting session's request.
The Free Buffer Waits Oracle metric wait event indicates that a server process was unable to find a free buffer and has posted the database writer to make free buffers by writing out dirty buffers.
There is another possibility - if the OP is using a keep and recycle pool: see http://jonathanlewis.wordpress.com/2006/11/21/free-buffer-waits/

What's the difference between Routing and Service Callout in ALSB?

I am puzzled by that.
what's the difference between them.
Or what's the situation should use Routing, and that of service callout?

There is little difference between routing and service callout.
Routing is symbolizes the transition of request thread to a response thread starts. (in OSB every invocation of proxy is undertaken by different request and response threads ). So by this definition, there can be only one route node in a pipeline.
Service call out is also used for similar actions as route node , but in pipeline. So service callout can be either in request pipeline (request thread) or in response pipeline (response thread ) . So in a proxy you can have multiple ServiceCallouts but only one route node.
There are some other slight differences.

What's the difference between *.JSP and *.DO?

Hi. I'm new to JSP programming and noticed that form actions call something like pageName.do -- what's the difference between the .JSP and .DO? When do you call one vs. the other? Thanks.

A request including the jsp extension usually refers to a single JSP file on disk that will be loaded and rendered directly.
A request including the do extension usually refers to a call into a special servlet that will redirect the request to another "controller" class which will in turn do some processing, and then load one or more JSP files to render the response.
The commonest form of the latter is the usage in the Struts framework. The do extension is not mandatory, it just presents a convenient way to distinguish calls that should be handled by Struts from requests for JSPs and other content that are mostly handled by the container (e.g. Tomcat) directly.

What's the difference between jsp and jsf?

who can tell me what's the difference between jsp and jsf?
I'm puzzled when I found some of the technology in jsp is so similar to the ones in jsp( javaserver page)

Hi,
Find the difference between JSP and JSF
1. A developer has more control with JSP, but (should) get easier development with JSF
2. Event handling is done differently in JSP (HTTP) and JSF (Java)
3. The UI is designed differently (or should be at least) with JSP (markup) and JSF (components).
4. The end product should also be defined differently - JSP page versus a JSF application.
Is this the only thing that is need to make a decision for either or? Probably not. There are other pieces that need to be taken in account when deciding which technology to use - tools support, enough components, type of application etc.... At this point there are not enough JSF components (although there are some interesting projects underway - Ajaxfaces, Myfaces, ADF Faces, and WebChart 3d) and enterprise tools support is still limited to a few tools vendor. Looking at our ADF Faces components they are currently available as early access (not production) and demands for these components are stacking up, literally, outside my office doorstep. Although I would love to make them production - now! - it is not a viable solution since we are still checking features and fixing critical bugs.
All this combined - not enough enterprise level components in production, lacking tools support etc... - leave customers in a vacuum where the decision is either to continue with JSP, since it is mature and has a wide developer base, or move forward with JSF not sure if the support, or the developers will be there. This is particularly sensitive to customers that need to get started now and be production by summer.
If you are in this vacuum here are some key points promoting JSF:
1. Fundamental unit is the Component
2. Built in event and state management
3. Component sets can be provided by any vendor
4. Closer to ASP.Net or Swing development
5. Choice of UI technology
6. Scale up (rich clients)
7. Scale down (mobile devices)
8. Built into J2EE containers in J2EE 5.0 (tentative)

What is the difference btw Oracle bpm 10gr3 vs albpm 6.0.5 version

What is the difference btw Oracle bpm 10gr3 vs albpm 6.0.5 version
Are the build number common to them?

Projects built in ALBPM 6.0 can be used directly in Oracle BPM 10g, but the reverse is not true.
It's sometimes thought that Oracle BPM 10g was just a relabeling of the predecessor BEA product ALBPM. This is not the case.
In Studio, standards are better supported:
<li> By default, new processes now use horizontal swim-lanes. You can change the swim-lanes orientation individually for each process. You can define the default orientation for each project and for your Studio installation.
<li> It uses more sophisticated BPMN icons. BPMN is the new default process diagram theme. BPMN constructs now include Gateways (AND, OR (new in 10g), XOR, Multiple Instance (previously Split-N)). A new Timer event was added. Loop conditions for automatic activities and groups were added.
<li> Studio now supports Mac/OS 10.4 Tiger and Mac/OS 10.5 Leopard.
<li> Studio now supports Windows Vista.
<li> Studio now supports CVS and Subversion version control systems.
<li> The Studio UI incorporates Eclipse 3.3 improvements such as the following:
<li> New Minimize/Maximize behavior: When minizing view stacks in Studio, the view icons are placed on the nearest trim area. If a view is maximized, all other views are minimized, rather than hidden.
<li> Interactive tasks provide a new "previewable" property. The new Application Display Panel and Task Execution Panel of WorkSpace automatically start the execution of previewable tasks without locking the process instance. Enabled by default for Dashboards.
<li> New type of Activity: Time Activity. A process instance that arrives to this activity just sits idle until a timed event occurs.
<li> Option Process Notification Immediately on Termination Wait activities has been deprecated. Now both the Wait activity and the first activity in the interruption flow always execute in the same transaction.
<li> Although I'm not wild about it, there is an auto-layout feature re-arranges all visual elements of a process diagram automatically, minimizing superpositions and aligning the flow as much as possible. Only available for processes with horizontal lane orientation.
<li> New process property (Greedy Execution Mode) indicates the Process Execution Engine to collapse contiguous automatic tasks in a single transaction. This mode of execution provides better performance for some processes. Disabled by default.
<li> A new Process-Level debugger allows developers to introduce breakpoints and debug complete processes running in Studio. When the execution reaches a breakpoint, the Engine pauses and Studio's debugging view appears. You can inspect variables, add new breakpoints, resume and continue execution.
User Interface
<li> The Business Analyst and Business Architect profiles provide a simpler set of menu options and toolbars.
<li> New editor for BPM Object Presentations. It's easier to use, provides a WYSIWYG drag and drop interface, improved CSS support and a new Drag & Drop toolbar.
<li> You can now interrupt a running Simulation started with the Run to the End button.
<li> New BETWEEN operator added to Business Rules editor (on both Studio and WorkSpace). This operator works with Time and numeric types.
<li> The Documentation View now displays read-only documentation for the standard Fuego.* components.
<li> New on-line help book Oracle BPM Components Reference provides reference documentation for the standard Fuego.* components. Only available for the developer profile.
<li> This version introduces Project Dependency, which allows you to re-use components and role definitions from a common base project.
In the WorkSpace:
<li> WorkSpace has an edit mode which allows users to change and save the configuration and layout of panels.
<li> A new tabbed interface allows you to define multiple pages, each with its own set of panels. You can export the layout configuration to an XML file and re-import it on a different environment or as a different user. Administrators can define layouts for all users in a certain Role.
<li> You can export the data in the Worklist panel to a PDF or CSV
<li> You can see an OOTB chart representation of the distribution of items in the Worklist panel.
<li> WorkSpace includes the following new panels: Task Panel: Renders the execution of interactive tasks within the panel, instead of using the default modal dialogs. Dashboard Display Panel: Provides a way to display Dashboards within a Panel. View Chart Panel: Provides predefined graphical reports about process performance, work items distributions and workload. Application Panel: This panel contains an application (the execution of a Global Interactive). Applications can respond to work item selections or run independently.
<li> The user can now do re-assignment operations on multiple instances at once.
<li> The Business Rules editor shows additional auditing information, including who and when a rule was modified.
<li> WorkSpace now (optionally) stores session-specific information as client-side cookies. This allows load-balancing on a cluster environment without affecting the user experience.
Integration:
<li> New timeout property added to external resources of type HTTP Server. Use this setting to control timeouts on web service invocations.
<li> Authentication information added to external resources of type JMS (Java Messaging System)
<li> Processes exposed as Web Services can now provide a runProcess operation, which synchronously executes the complete process (from begin to end). Only meaningful on fully automated processes.
Enterprise:
<li> New Ant tasks to rebuild the Oracle BPM web applications for container-security.
<li> Configuration Wizard adds option Generic JNDI to the list of available LDAP servers. When using this option, you must provide a custom configuration file defining the mapping of object classes, attributes and filters. This new feature is also the new mechanism for integrating with AquaLogic Interaction 6.5, replacing the old Identity Service.
<li> Configuration Wizard can now be run without user interaction ("silent mode"). You specify all configuration values in an XML file.
<li> Oracle BPM client applications (including WorkSpace, PAPI-WS and custom PAPI apps) are now able to connect to multiple environments (BPM Directories) simultaneously.
<li> Added Sybase as a new provider for the Engine database and BPM Directory database.
<li> More information added for auditing of Business Rules, including who and when a rule was modified.
<li> Updated bundled JDBC drivers to their latest version.
<li> The Engine now logs warning messages when it detects rogue threads. A new preference allows the administrator to disable automatic re-starts when the Maximum Number of Rogue Component Executions is reached. In addition, in the case of an automatic re-start the Engine now logs a complete thread dump.
<li> Simplified procedures for deploying BPM WorkSpace on WebLogic Portal. BPM Process Administrator now generates the WorkSpace EAR file as a WLP library module.
<li> Authentication information added to external resources of type JMS (Java Messaging System).
