JSF and Struts - differences and integration goal.

I am a newbie J2EE developer and I am not clear about main differences between JSF and Struts also I saw couple of articles describing integration between JSF and Struts. Could someone give me an explanation, what the main conceptual differences between those technologies and what's the goal of integration both of them?

I describe the main differences between JSF and Struts in this sample Chapter from my JSF book:
http://www.oreilly.com/catalog/jsvrfaces/chapter/ch01.pdf
Hope that helps.

Difference between unit testing and integration testing

What is the difference between unit testing and integration testing in SAP? Is unit testing takes place in Dev client and integration testing takes place in QA system?
Please clarify
thanks

Hello Krishen,
unit testing means veryfiingsmall / the smallet pieces of software, while integration testing checks the overall functionality of applications. Within the AS ABAP the tool ECATT + manual tests is used for integration tests and the ABAP Unit language integration for unit testing.
When, Who, Where tests are carried out is ultimately a personal decision. As unit tests are operate even under heavy development they are often the first choice for developers, but the unit tests can also serve for regression tests over a long period. Integration tests tend too be created and executed in later stages as they require often a certain majurity of the software under test.
Beside the mentioned links you may check out ABAP Unit infos also in the Wiki.

Difference between Integration Process and Monitoring Process

Hi Experts,
What is the difference between Integration Process and Monitoring Process available in PI7.1?
SAP says that Monitoring process is a special kind of integration process that receives the event messages.
My doubt is even integration process can receive the event messages.
Why these two different type of entities are created for the same purpose?
And what is the technical difference between the two in terms of PI perspective?
Regards,
Sami.

My question is now answered.
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70a25d3a-e4fa-2a10-43b5-b4169ba3eb17]
On page 17 of this pdf following sentence is mentioned :-
From technical perspective, there is no difference between monitoring process and integration process.
Though logically those are two deifferent things.
Monitoring porcesses are used to receive only event messages that is comprises of event data only.
Like Purchase order creation is a event and its event message will have the event data like Order Id, Created on, Created by, Quantity etc., instead of whole purchase order.
Where as Integration Process is a way to provide solution in some specific circummtances like where we have to automate our process or where we need something in between for the course of communication.
Guys thanks for your precious time.

Sami.

Differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity ConstraintsConstraints are to be preferred:
"Declarative Ease
Define integrity constraints using SQL statements. When you define or alter a table, no additional programming is required. The SQL statements are easy to write and eliminate programming errors. Oracle controls their functionality. For these reasons, declarative integrity constraints are preferable to application code and database triggers. The declarative approach is also better than using stored procedures, because the stored procedure solution to data integrity controls data access, but integrity constraints do not eliminate the flexibility of ad hoc data access.
Centralized Rules
Integrity constraints are defined for tables (not an application) and are stored in the data dictionary. Any data entered by any application must adhere to the same integrity constraints associated with the table. By moving business rules from application code to centralized integrity constraints, the tables of a database are guaranteed to contain valid data, no matter which database application manipulates the information. Stored procedures cannot provide the same advantage of centralized rules stored with a table. Database triggers can provide this benefit, but the complexity of implementation is far greater than the declarative approach used for integrity constraints."

Difference between Monitoring Process and Integration Process

What is the difference between the Monitoring Process object for BAM and Integration Process object? Both seem to have exactly the same design environment in the Enterprise Services Builder.
Is it so that Monitoring Process alarms only appear in the UWL of the specified user?
Also, suppose I am wanting to create a receive step to wait for the arrival of a message instead of an event (say I want to check a specific message arrives before a certain time, correlating several fields of the message, which is something I cannot do I believe with alert monitoring). Am I able to do this? I cannot see a reason why not, but I'd like confirmation.
BR,
Tony.

Hi,
Thanks for the link! I read through the replies, but it still leaves a couple of basic questions unsolved:
1) Why did SAP discriminate these two types of PI objects at design time - the Monitoring Process and the Integration Process?
2) new capabilities of PI 7.1 are touted as:
Event provisioning and consumption for BAM:
- Local container
- Subscription and handling of business process events
- Milestone Monitoring
So can I only employ event provisioning, subscription of Business process Events and Milestome monioring with a Monitoring process, or can I do that with an Integration Process as well?
BR,
Tony.

JSF vs Struts And Best O/R mapping tech.

I want to start working again after 3+ years gap from 2003 to 2007.Earlier for 4 years I have worked on web/enterprise applications and technical platform was JSP1.2,SERVLET 2.x,Oracle's xsql servlet,JDBC ,Struts1.0/1.1,statleless Session Bean ,Web Service generated by BEA WEBLogic server 8.1,jdk1.3.
I've been looking through too many documents and forums, there are so many choices now .Could you please suggest which of the following should I learn to update my skills :
1.JSF OR Struts 1.2,1.3 OR Struts2 ( There are no books for Struts 2)
2.Hibernate OR EJB3 OR Torque OR TopLink
3. jdk 1.4 OR java 5
Can you help me to findout documentation and tutorials to learn these .
Thanks

You're wanting to get back into writing web applications?
Web services?
1 - If you worked with struts before, I'd probably continue with that line. Or at least start there.
2 - I'd say Hibernate, but then I don't know that much about the others ;-)
3 - Java1.5.
I would also recommend you catch up with the changes between JSP1.2 and JSP2.0, particularly regarding JSTL and EL.
For learning JSTL, you can't past go the JSTL spec. It is quite readable, and an excellent reference. http://java.sun.com/products/jsp/jstl/reference/api/index.html

Difference between Workflow and Integration Process

Hi Experts,
Can someone please explain, what is the difference between the workflow and integration process(BPM).
Thanks
Sree

Hi Sree,
Integration Processes are :-
--Message based
--Interface focused
--Cross component
--Have no support for human interaction
--Enabled with SAP XI
Workflows are:-
--Object based
--Human focused
--Intra-application
--Have no support for mapping, routing or message transformations
--Enabled with the SAP Web AS
However, most automated business processes involve a combination of the two.
I hope this clear your doubt.
Regards.

Difference between IntegrationServer and Integration Engine

Hi,
Could you please provide me difference between IntegrationServer and Integration Engine.
functionality of both and what are the runtime environments exits in XI Server.
Could you please show me digaram how message flow from
XI server i.e., through which engines.. what is the input and output of each engine.
Thanks,
RamuV

Hello Ramu,
Go through this link..
http://help.sap.com/saphelp_nw04/helpdata/en/e1/0c733cb7d61952e10000000a11405a/frameset.htm
Use
Two SAP XI 3.0 Integration Servers are used to exchange messages between the system landscapes of two business partners.
Description
An SAP XI Integration Server of a business partner is connected to the SAP XI Integration Server of another business partner. Both use SAP XI message protocol to send or receive messages.
When an SAP XI Integration Server receives a message from another Integration Server it understands the message format and so processes the message.
Example
A business partner that uses SAP XI wants to send a message to another business partner who also uses SAP XI .
·        The message is sent between the Integration Servers in SAP XI message format
·        The Integration Server of the second business partner then sends the message to the relevant business system
Integration Engine
Purpose
The Integration Engine enables you to process XML messages exchanged between applications in heterogeneous system landscapes. Both applications of SAP components and external applications can communicate with the Integration Engine.
Using adapters, the Integration Engine can also process IDocs (Intermediate Documents) and RFCs (Remote Function Calls). This option is available for applications that have already defined IDocs or RFCs, as well as for applications of SAP components that do not yet have access to the proxy generation functions.
Integration
The Integration Engine is the runtime environment of the SAP Exchange Infrastructure. The following are examples of other important parts of this infrastructure:
·        Proxy Generation
·        Integration Repository
·        Integration Directory
The integration processes involved can take place between heterogeneous system components within a company, as well as between business partners outside company boundaries.
Features
The Integration Engine, as a runtime component of SAP Exchange Infrastructure, has the task of receiving, processing, and forwarding XML messages. During message processing, collaboration agreements are evaluated, the receivers are determined, and mapping activities are executed.
The individual processing steps are called pipeline services and are defined in pipelines. It is the task of the Integration Engine to process these pipelines correctly and consistently. To guarantee this, you must configure the Integration Engine accordingly and monitor the message processing. Both event-driven message processing and prioritized message processing are possible.
Thanks,
Satya Kumar

Difference between Integration Engine and Integration server.

can any 1 explained in detail about difference between Integration Engine and Integration server.
thanks in advance

Integration Server and Integration Engine are used synonymous with each other. But there is a sublte difference if you actually look into the XI architecture images provded by SAP.
The Integration Server contains,
1. Adapter Engine
2. Business Process Engine
3. Integration Engine.
So, taking this into picture I guess Integartion server is a collection of these 3 while integration engine is one of the runtime components of XI. All messages are processed in the Integration Engine.

Difference between JSF and JPF from WebLogic workshop

Hi i am new to JSF , currently i am working on JPF and i got a chance to work on JSF..
I feel that event drivent programming as same as JSF and In JPF.
Can any body explaine in detail difference between JSF and JPF
Thanks in Advance
Suneel.

JSF is Sun's MVC framework for web applications.
I've never heard of JPF, so it might not be part of Sun.

Difference between jsf and jspx

Hi
We can develop a adf page in either jsf or jspx. What is the difference between jsf and jspx?
which is more compatible in adf and why?

Hi.
The main difference in the version of JSF you are running on. In JSF 1.2 and lower, you built JSP pages. The JSPX extension means it was a JSP page using XML markup. This was (and still is) the default option in JDeveloper 11gR1.
JSF pages, introduced in JSF 2.0, use another view declation language called « Facelets ». They are the default in JDeveloper 11gR2 and will be in 12c as well.
Both standards are compatible with ADF. If you are building a new application, JSF is the way to go as it will offer you more flexibility and represents the best option going forward.
Best Regards,
Frédéric Desbiens.

JSF and JSTL integration

Can anyone tell me how to access JSF objects from JSTL tags?
I want to set a requestScope flag in my changeListener
... context.getExternalContext().getRequestMap().put("xxx","ok"); ... and render output depending on existance of this flag:
...<c:if test="${requestScope.xxx!=null}" > .... .
This examplecode doesn't work, JSTL tags cannot access this var! How can I do that?
What I realy want is to reload another frame when user changed a specific input field.
Above code should add a JavaScript to reload the frame if this is true .
I can't do this on submit because the other framepage uses the stored/modified data.
Maybe there's a better approach for this anyway?
Thanks for your help!

Thanks for your help - I found it was my own mistake why it didn't work. Now it does, as you said.
But in the meentime I ran into another Problem mixing JSTL und JSF:
I want to build a SelectOneMenu and populate it with data from a database, but with selectItemValue
other than selectItemLabel (value should be numeric DB-ID, label a readable name).
Since "selectItems" allows only one dimensional Arrays (?) as parameter, I must use "selectItem" for
each row. So I wrote following code:
<h:selectOneMenu id="m1" value="#{worktime.employee}">
   <sql:query var="employees" dataSource="jdbc/WebOfficeDB">
       select oid,displayname from employees order by displayname asc
    </sql:query>
    <c:forEach var="row" items="${employees.rows}" >
       <f:selectItem itemValue="#{row.oid}" itemLabel="#{row.displayname}" />
    </c:forEach>
</h:selectOneMenu>This doesn't work, I get NullPointer Exceptions from selectItem.setValue().
I think because JSF "#" references another context than JSTL "$" - is this correct?
So I tried to set a JSTL variable inside the forEach loop to access the datarow
<c:set var="data" value="${row}" scope="request"/>
<f:selectItem itemValue="#{requestScope.data.oid}" itemLabel="#{requestScope.data.displayname}" />
...The effect is that all lines of the selectOneMenu have the same content (from the last datarecord)!?
Since this is my first project in JSTL and JSF and should stay a small one I don't want to go into building
CustomComponents and so on for such a simple Task.
I would be very very happy for some tips and hints, since I think this mixing of JSTL and JSF Context
will be a very common problem within my project.
Thanks

[ANN] JSF and ADF Faces Q&A online session today

Join us for an online discussion and ask your questions about JSF and ADF Faces. Today (Thu) at 10:00am PST (California time).
http://www.oracle.com/technology/tech/java/newsletter/seminars.html

Great here are a few IF there is time:
1. How round trips will JSF and ADF Faces take upon initial page load? In other words, does the initial page load come with data already populated? This makes a difference for those of us who have data heavy pages with lots of lag. Currently with ADF - UIX it seems as though the page is loaded and then round trips are taken to populate the data in the page.
2. Is a JSF and ADF faces project in future versions of JDeveloper more easily/efficiently source controlled than current ADF/UIX projects?
3. What is the extent of the involvement of the struts framework in JSF and ADF Faces?
Thanks very much Shay.
