Difference between EP and Web AS JAVA

Hi all,
I am new to EP. I wish to know the clear differences, if any.
I work in a project where there is an enormously complicated landscape. There is a 'central portal' (EP 7.0); services from backend ABAP systems are accessed. Every ABAP system (ECC, CRM, BI, XI etc.) has a corresponding Java system (Web AS Java's). They seem to be referred to as 'portals' too. I see that EP and the Java systems are same; look and feel wise. I see that we can do user/system/content administration in both of them.
What are the fundamental differences, if any? Help!
Thanks and regards,
Rosun

Hi,
the best person to answer your questions is the person responsible for the landscape at our company. To differentiate between Web AS Java and Portal: The portal is an application that runs on top of Web AS Java. GRC runs also on top of Web AS Java, but it's not the portal. Look at Web AS Java as it is a Java application server like JBoss or glassfish.
Without knowing the details of your landscape it's hard to give you an answer. In a complex SAP landscape you may have:
- a ECC system and a portal for ESS/MSS
- a BI system with a portal for accessing the BI reports by a browser
- SRM system with a portal that serves as an access point to IACs or POWL
- CRM is using nowadays BSP (ABAP)
- a central portal system that unifies the access to the other systems. In this case, we are talking about Federated Portal Network (FPN)

What's the difference between "overloading" and "overriding" in Java

What's the difference between "overloading" and "overriding" in Java

hashdata wrote:
What is the real-time usage of these concepts...?Overriding is used when two classes react differently to the same method call. A good example is toString(). For Object it just returns the class name and the identityHashCode, for String it returns the String itself and for a List it (usually) returns a String representation of the content of the list.
Overloading is used when similar functionality is provided for different arguments. A good example is [Arrays.sort()|http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#sort(byte%5B%5D)]: all the sort() methods do the same thing (they sort arrays), but one sorts byte-arrays, another one sorts int-arrays, yet another one sorts Object-arrays.
By the way, you almost certainly mean "real-world" usage. "real-time" (and thus "real-time usage) means something entirely unrelated to your question.

Hi Harpreet:
ITS is basically the tool that allow you to use SAP via http. Theres lots of info about <a href="http://help.sap.com/saphelp_nw04/helpdata/en/0d/654d356560054ce10000009b38f889/frameset.htm">ITS</a> or <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/5f/0ef441ad7bc417e10000000a155106/frameset.htm">WebAS with Integrated ITS</a>
The ITS is a standalone application connected to R3 via RFC connection, In the SAP WebAS the ITS is integrated to the system.
Hope this help!

Differences between eCommerce and Web Channel

Hi. I'm really new to SAP. I'm looking at leveraging some of the built-in e-commerce functionality of SAP. I've read a few articles on the SAP help site but I can't distinguish the differences between the following 2 solution options:
1) ERP eCommerce
2) CRM Web Channel
From what I've read, both of the above technologies do relatively the same thing. Can someone let me know if this is true, or if not, where I can find details on when to use one versus the other?
Thanks!
- Dylan

Hi,
please let me try to clarify this.
Both of the solutions are actually based on the same Java web applications. This means both applications share the same core functionality. The main difference between ERP eCommerce and CRM Web Channel is the backend system used for the web shop.
The reason why SAP offers two different backends for the web shop is pretty simple. Each backend is suitable for different requirements. While running the web shop with a CRM backend, some additional features related to the marketing functionality of SAP CRM are available. These addtional features include cross- and upselling, campaign management and advanced catalog management. For customers that don't need these marketing features or don't want to invest in a SAP CRM system, there is the ERP eCommerce solution. While the shop system is the same, some of the additional features offered in the CRM version are missing.
I hope that solves the problem for now. If you have more questions on the difference between the two solutions please let me know.

Difference between Client and Web

hello
i am newbie to EJB, I have started the online tutorials, on this tutorial nothing has mentioned about the difference between application client and Web application.
I am sort of confused why do we have to have both of them?
I know that web application should run from a web browser, but what happens if i ignore the application client?
I am trying to make a simple application to use ejb which connects to a databse and a web application to show the results. Can i just develope ejb and a set of jsp to interact as web application?
could someone help me please
cheers

The difference is simple:
A web client is a so called 'thin client' just displaying the information created and processed somewhere else.
A standalone client is a fat client which uses the ejb only to retrieve data and manages the user interaction by himself.
So a web application is basicly a fat client wich uses a web browser as a display (web browser is a display) thats why you have to implement a set of jsp and servlets which present the data to the user.
I you want e.g. a java program to interact with your beans to get data from the database you will have to code an application client. But it doesn seem like this, so your idea is right. Have fun implementing...

Difference between RSPOR_T_PORTAL and TC:RSRT- JAVA Web

Experts:
I remember that the following 2 URLs should be the same:
1) the entry in table RSPOR_T_PORTAL and,
2) the URL of the web page launched by T-code RSRT->Java Web.
I cannot find the document explaining why they should be the same.
And if they are not the same, will it cause any problem?
Thanks!

I reckon
2) the URL of the web page launched by T-code RSRT->Java Web.
will call RSPOR_T_PORTAL to check the DEFAUL Portal.
RSPLAN, RSRT, BIWEBAPPS will call this table to check the Default Portal.
Thanks

JNDI differences between Tomcat and Web Logic 6.1

I am looking at two difference piece of code :
Application developed and deployed under Tomcat ( perfectly working )
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:comp/env");
// Get a Connection
DataSource pool = (DataSource) ctx.lookup("jdbc/WebApps");
// Getting connection
con = pool.getConnection();
This is instead an application developed and deployed under Web Logic
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("dbase");
// Connection
con = ds.getConnection();
when i deploy the WL application in Tomcat ( as a WAR file ) I got "dbase name not bound in this context", any guess why this is happening even though I already set up the server.xml :
<Resource auth="Container" name="dbase" type="javax.sql.DataSource"/>
<ResourceParams name="dbase">
<parameter>
Unfortunately I cannot rewrite the WL code so I need to work on Tomcat
Thanks in advance
Leonardo

Thanks for your reply,
However I think I have not been clear.
This is the situation. We have Web Logic on production and Tomcat on our Intranet.
So I am in need of making the WLogic app working under Tomcat "Without touching the code" of the application. The only thing I can modify at this point is the Tomcat installation. If it's possible.
The only problem I have is with the piece of code of the Data Base Connection. I got "dbase is not bind in this context".

Communication between BSP and Web Dynpro JAVA

Hello All!
I'm wondering whether the communication between a web dynpro application and a BSP application is possible.
To ellaborate more, we have developped a web dynpro application acting as sender and we would like to develop a bsp application that displays a smart forms and which needs to listen to the web dynpro. We don't know exactly how to do that.
Your help is really appreciated!

Difference between webpublish and web gui builder

Have you worked with webpublishing tool in LABVIEW 2013 before? Do you think I can show my front panel which is designed in Labview fully on the web by this method?
Please make your advice about it. I have studied few articles about web gu builder, webpublishing and webservers but I am still not clear which one can simply satisfy my objective?
My objective is to display the graphical front panel which is designed in labview .vi exactly on the web.

Portal Servers are usually Application servers which host a
variety of Applications, Portals as a concept are single Gateway
to whole lot of information and applications(could be
distributed across systems, generally Web based ones).
Eg. BEA Weblogic Portal
Content Management systems are applications to Capture, Manage,
version, distribute and Store content. Content can be Structured
and Unstructured. Generally I have seen when CMS word is used,
it means Web Content Management, although this is not a norm
across the industry.
I am sure you are aware of WCMS and ECMS differences.
E.g Interwoven TeamSite, Documentum, OpenCMS etc.
CMS facilitates the ready availibility of content to be shown on
Portal in large Portals (the concept). This content could be
sourced in from various systems and distributed by the CMS.
Essentially any CMS deals with Content Creation, Content
Management proper, Content Intelligence and Content
Distibution.
However important thing to note could be the emerging products
which are Portals and have a built in CMS tool also, like BEA
(Aqualogic in particular). There is another genere of products
like Vignette, Broadvision which are Portals and CMS both in one
(have CMS products built in but as a seperate component).

Differences between Hyperion Workspace, Web Analysis and Financial Reportin

Hello,
Can anybody explain me the differences between Hyperion Workspace, Web Analysis and Financial Reporting?
Thank you

In real simple terms....
Financial reporting - Perfect for producing standardised monthly reporting such as P&L, balance sheets etc. Highly formatted, print well in PDF format.
Web Analysis - Highly graphical, web based analysis tool more suited to dashboards, pinboards etc with slice and dice capability.
Workspace - Common environment where reporting content in deployed. Users can access web anlysis, fin reports, Interactive reports plus other content through the workspace. It was the start of the 'log on to one place for all reporting' concept instead og logging on to multiple products.
Hope that helps
Regards

What is the difference between ERP2004 and SAP 47 Enterprise?

Currently we have SAP 47 Enterprise with WAS 6.2. I understand ERP2004 is NW and 6.4 sp9. Can any one please let me know the major difference between ERP2004 and SAP 4.7 Enterprise ( more from abap / workflow view)?
Thanks
Swamy

From Abap point of view some of the major add-on in erp2004,netwever :
1) Development of webdynpro studio for java development for portal and iviews.
2) Major abap development uses <b>Abap object oriented</b> methodology, rathet hten old conventional Abap,i.e MVC model (Model,View,Controller) where in it uses concept of classes,interfaces,etc.
3) Advanced BSP tech using MVC model to develop web based modules
4) It is closesly integrated with web-based CRM and BW/APO
