BI - Java front end ...multiple BW abap back-ends?

Experts,
we have a BI java/portal running NW7.01sp6 (portal/BIjava application types). We have used the config wizard to successfully connect to our BW NW7.02 abap back-end in order to run bex, etc.
My question is this:
Is it possible to connect the BI-java portal to multiple BW abap back-ends? Or should we have one BI-java portal for each BW abap back-end?
This may be the wrong forum for this question. If so, please forgive me and point me to the correct one.
Thanks
NICK

Hey Judith and experts,
I found this note:
Note 919197 - Troubleshooting: More than one master system found
In there it states:
Each SAP Web Application Server Java always has precisely one SAP Web Application Server ABAP, which serves as a BI master system. The metadata for Web items and Data Providers is read from this system, for example, and this is the only system from which you can start Web templates and Enterprise reports.
If you want to display Web templates that originate from more than one SAP Web Application Server ABAP in an SAP Enterprise Portal, for example, you can use the Global Portal technology.
Does anyone have any idea what they mean by "Global Portal technology"? Or should I just bite the bullet and install another BI java portal to go with the ABAP instance.

Java Front End, PHP Back End

Hi all, I am trying to create a java front end with a php back end. Using a tip from Core Java Technologies Tech Tips (http://java.sun.com/developer/JDCTechTips/2004/tt0210.html#2). I tried to convert their code from a command line to a GUI and have gotten preaty far but it is only allowing me to get one row of data from the php file. Here is my code so far:
package test;
import java.net.URL;
import java.net.MalformedURLException;
import java.net.URLConnection;
import java.io.IOException;
import java.io.BufferedReader;
import java.io.InputStreamReader;

public class test extends javax.swing.JFrame {
private static URLConnection connection;
private String inputLine;
private static void connect( String urlString ) {
try {
URL url = new URL(urlString);
connection = url.openConnection();
} catch (MalformedURLException e){
} catch (IOException e) {
private String readContents() {
BufferedReader in = null;
try {
in = new BufferedReader(
new InputStreamReader(
connection.getInputStream()));
String inputLine;
while (
(inputLine = in.readLine()) != null) {
return(inputLine);
} catch (IOException e) {
return inputLine;
/** Creates new form test */
public test() {

I am preaty new at java, I know PHP preaty well though so something like this could help me out alot. Most of this code was generated with the help of Netbeans.

I dont see why it would unles it has something to do with your URLConnection being static. setText() is only going to give you one line as well. try
jTextArea.append(inputLine);
and make only one declairation of inputLine.
The only thing that should be static in your code is the main method.

Using Air 2 as a java front end in a project idea

I watched this video on adobe tv where this guy called java process through air 2's new process invoking methods, and what I wanted to do was something simular. I have a java project that interacts with JBDC to talk to the oracle database, and currently can add, create, remove and bla to tabel entries.
what I want to know is the HOW DO I, make air talk to java...How do i make air the front end, and java the back end with out using servers and third party applications.

I think you may have to look at all your jar files in the project including struts jar packages, and watij home page, and verifying they all are java5 compatable. My guess is your error is caused by watij using java reflection to do something (assuming there is nothing in the project or struts using reflection) . You may try creating a small struts project that is java5 compatable and seeing if you can use the watij tool on it without an error. That way, you will isolate problems with watij and struts problem with java5, from who knows how many other problems the major project has with java5. Are you using a server such as tomcat? that has to be compatable with java5 too.

Java Front-end problems with Windows 200 Pro

Hi,
I have some problem on my pc with java applications front-end. I have windows 2000 Professional and use java(TM) 2 SDK, Standard Edition Version 1.3.1
Using every java applications (also development environment as JBuilder 4 Professional and Together 4) I have always problems with front-end: the text is bad visualized everytime I use the scroolbar, menu items into a menu are bad visualized while I drag over of them the mouse and so on...
To try to solve this my problem I have just installed Service Pack 2 for Windows 2000 Pro but I have not had good results - I keep to have the usual problem.
I'm aware that it is difficult to reproduce and however if anyone has some idea to solve my problem I am opened to every suggestion.
Thanks in advance

the text says that what technolody that they are using its called "Off Screen Images" once i used them in my applications to improve the prefomance.
What they says is to improve the time it takes to display componants that display text on them (Such as buttons, Labels...) they going to create an Off Screen Image of the text and then paste that image on to the screen whenever the componant has to be displayed/Re displayed instead of redrowing (Re rendering) the text on the screen repeatedly which take more time and processing power than rendering once and paste it to screen whenever needed but this solution will take some more memory.

Coldfusion back-end, AngularJS front-end, and Security

The company I work for is building an application in which security is of the utmost importance. We're really hoping to use Angular as the client-side application, and we're exploring how best to create our back-end in ColdFusion (which we've used for a few years now).
I understand that only so much security can exist in the front-end of the app, and that the bulk of the work needs to happen on the server. But I'm really unsure about how to move forward in that regard. From what I've read, it sounds like we'll need some kind of Authentication Token to be created on login and stored on the backend. This token should come along with every http request, and the server can then decide on the validity of the request.
Does this sound about right? And if so, are there best practices for implementing it?
Any resources that might shed more light on the topic would be HUGELY appreciated.
Thanks,
Jonathan

More and more teams in my company are now mixing technologies. For example they use java for the back end and C# for all the client side code i.e GUI.
How can you mix these technologies. Ie how can c# code "talk" to java code?
Not sure if this is the best place to ask, as its a java forum but I though I would give it a try!
ThanksSimplest way would be to use web services.It is new thing for me to learn...
How efficient to do it compared to all in one either C# or java? I guess it would be slower.
Either C# or java can handle the job. Why both? I don't get it.It all depends on how big the teams are and how much "separation of concerns" you are looking for. In enterprise architecture what i aim to do is try to give the development groups freedom to use whatever technology they feel best suits their need...BUT...if they want to talk to other systems and vice versa, they have to follow certain standards (SOAP, REST etc). Architect the lines, not the boxes. If you are not looking for separation of concerns, sure build out everything in one technology..but keep it mind future changes.Thank,
It is good thing to learn. I used to work with java front end calling Cobol back end (using transactions)
I know C# and java can talk by SOAP or web services but only wondered about the reason.
If I am going to design everything new, one technology is the answer.

Authentication with UME separation of front end and back end

My webdynpro project has 2 application. One for Admin one for Rating.
Is it possible to create a java class at Webdynpro level and share it between the 2 applications?
Why the need?
Created a custom class (lets called it CommonEJB), to point to the right pages and set of UI controls after the initial login with UME. This class utilizes the IWDClientUser.getSAPUset() method to get IUser object.
If it is not possible to create a java class at Webdynpro, then this ejb will need to be deployed to the backend.
Putting it at the backend is not good as security wise, its always better to separate the authentication between front and back end.
Any ideas/solutions?
thanks

Well, i wish to create a java class that can separate the view areas depending on their login.
lets say you're a manager, u can see certain views. and if you're a supervisor u see another. This is achieved using the java class with information from getSAPUser() position. After retrieving the position, using the java class will programmatically assigned the appropriate views, buttons, tabs etc.
so this class need to in front end, and not back end. problem is we have 2 application.
if the class is created front end in one application can it be shared with another.

TMG2010 - Front-End (DMZ) / Back-End (Internal) - Reverse Publishing. Exchange 2010

Hey Guys,
I need some help conceptually understanding how TMG2010 is used in a front-end back end scenario. For Example:
1) The client would have TMG2010 in the DMZ
2) The client would have TMG2010 in the Internal Network.
3) The client would have multiple Network Cards (2-Leg's) on each of the TMG boxes
My question is definitely design related so my apologies if its a little confusing. Would the correct way of setting up TMG securely be the way i have described? If so how would you set the Auth type? Do you know of any design documents that cover my scenario?
What i am really confused about is the Authentication Type for each of the TMG servers (Front-End, Back-End) and if those servers would both be joined to the domain or not.
Thanks,
Robert
Robert

Hi Robert,
Various way to do it however below are one method of Doing it.
Internal TMG
Internal TMG can be joined to Domain
Two LEG TMG
Once NIC connected to Internal network Switch
Other NIC Connected to DMZ Switch ( Which Routes Traffic to External TMG internal Interface )
External
Workgroup
One NIC connecting to internet Router
Other NIC connecting to DMZ switch
Network relationship can be NAT between TMG, You can use the Internal TMG as Proxy / Web Publishing / Server Publishing etc. Use the External TMG as plain firewall and to NAT Internet Inbound Request to back end Firewall External Interface IP address. Malware
/ NIS can be enabled as per your requirement on any one of the TMG.
Additional to It
You can Configure one More LEG a third Interface on Both TMG
Configure External DMZ on the Third Interface on External TMG. External DMZ will be only Internet Facing
Configure Internal DMZ on the Third Interface of Internal TMG. You can Use it as Inside DMZ.
Hope this helps
Thanks for the response. But what about the Authentication? How would that be setup? I am still unclear on that part of it. For Example:
In my lab i have the following:
1) Single Armed TMG server
2) Auth set to NTLM/Integrated on both TMG and Exchange (OWA). Other Auth settings for other exchange services
3) Single Listener, SSO Across AD Sites
4) TMG is only providing Reverse Publishing, no other network security services.
If I added another TMG server as a front end how would i configure the Authentication for the above scenario?
Thanks,
Robert

Front end Java classes?

Aloha all-
I'm familar with using LiveCycle Data Services with Flex and love its use of front-end ActionScript classes that map back to the server. I was wondering if such functionality was possible with Java classes? My guess is no, but wanted to make sure as I've been going through the docs and haven't found anything explicit.
Basically, I'm thinking about using LiveCycle DS in an all Java project (Swing front end) and if it communication could be handled by DS, which I'm familiar with, instead of creating my own JMS topics, that'd be great. Plus it provides a way to move the app from Java/Swing to Flex/Air.
Ron

Hi Ron,
We don't currently provide a client-side Java API for LC DS.
If you plan on switching from Swing to Flex/Air in the future, the major thing to watch out for is that the classes you ship over the wire from the server to the client adhere to the Java bean serialization rules that Flash AMF serialization requires (no-arg constructor, public get/set methods for properties, etc.). But you should be able to expose the same server code to a Flex/Air client with minimal to no impact.
Porting your front-end app from Swing to Flex/Air wouldn't offer any opportunities for client-side code reuse.
Best,
Seth

Calling Java APIs from Adobe AIR Front End

HI ,
I have developed an desktop application entirely in java.
Currently it is console based, but i am planning to have a UI for the same in Adobe Flex.
I wanted to know how do I communicate between the two, ie call methods that are defined in my java classes from AIR and return results to Adobe AIR.
There is no server involved.
I want to keep Adobe AIR as front end and Java as back end which will take care of the business logic .
Thanks and Regards,
Santoshi

The best way is probably to use the NativeProcess APIs available in AIR 2 (now in Beta).
Next, would be to use sockets to communicate between the two processes. In AIR 1.5, it is difficult to guarantee that both processes are running, at least when controlling thins from the AIR side rather than the Java side. In AIR 2, you can start other processes, so this is also easier.
There are some 3rd party tools, like Merapi, that help you pass objects between Java and AIR, too.

In the front-end editor (new) when we type the coding we can see the syntax which is highlighting in the top. how can we get that without entering. in java eclipse, if we give a space that syntax will apply. is there any such fuction in ABAP.

here that can be done with the help of TAB button.

Front end and back end questions

Hi,
If I want to develop a web base SOA application by using Jcaps, I have several question want to ask.
1.) In the front end, if i create the page by using eVision to create the page
flow and the page layout, how can I match the fields of the page (such
as the username, email, tel no... with the back end web services?
2.) Does the flow of the front end web pages are control by the page flow in
eVision? When will the eVision supported AJAX or JSF?
3.) What is the use of the eInsight Business process manager, does it
control all the back end flow, such as the flow of each web services?
Does Jcaps has the Bpel engine to control the flow of web services?
4.) I know that in JBoss, there is a jBPM server to control the flow of the front
end pages, does JCAPS has this kind of server?
5.) If i want to connect to the Database? I know that there is a eTL to extract
the data from the database, it is true? Or do u recommend to connect the
database directly through the web services by using JDBC or other
framework as well?
6.) If I have an existing application that is developed by .Net (With no web
services). How can i integrate with other systems? What can I do in order
to reuse the system? Or what Jcaps can do in this manner?
Thanks for you reply! ^ ^

Generally, back-end would consist of the taks associated with configuration of data targets (ODS, Cubes), working with extractors, mapping data to the data targets, writing transfer/start rtn/update rules, and creating Infopkgs/ Process Chains.
Front-end deals with the use of the BW - writing queries, workbooks, web (although I think some of the infrastructure aspects of web reporting. e.g. javascript/templates might really could be considered backend). Think of Front-end as all of the client/customer/user facing components.

What is BW Front-end and Whats BW Back-end? Technica ? Functional?

Hi Gurus,
Can some one throw light on the diff between a BW Front-end and BW BAck-end? How will u diff the responsibilities of a Functional BW Consultant and Technical BW Consultant?
thanks
kishore karnati

Hi,
BW Front end is the one that deals with reporting. Eg: BEx
BW back end is the one that deals with the components that stores data which is used for the reporting purpose.
Eg: R3
Functional consultant comes into picture when there is a need to understand the functional aspects of a requirement, say for example, you have a requirement to use Sales Order in your BW application, as a pure BW person, you wont know what a Sales Order is about. A functional consultant has the ability here to map the sales order requirement in the BW application. This means that, he knows what field and what table this sales order relates to. This way, a functional consultant maps the user requirements to the technical detail in the system.
A pure BW consultant is one who knows how to setup data extraction from source system , how to build various components in a BW system, how to schedule a load, how to troubleshoot in case of any issues in the BW application.
Hope this helps..
Assign points if this helps...
Thanks,
Raj

Regarding connection between front end HTML and back end SQL 7.0

Hi!!
I am working on the project 'ERM'. I have designed 12 forms using HTML. Can u please give me brief idea how to establish the connection between a back end and front end i.e. between HTML and SQL 7.0. If possible can u provide me the source code for the same.
I will be very thankful to you.
Thanks,

Read up about multi-tier applications.
You need servlet and JSPs for the server-side presentation layer, some classes for the business logic, and some mor for the persistence layer either using JDBC or some framework like Hibernate.

Upgrade to SAP BPC 7.0 with cluster system (Front-End & Back-End)

Hello,
I have to do an upgrade document about an outlooksoft 5.0 SP2 to SAP BPC 7.0 SP4 in a cluster system.
It has 2 front-ends (IIS cluster windows) & 2 back-ends (SQL Cluster).
We are going to do first the migration in 1 node, and then in another. The first upgrade in the first node I understand. I uninstall outlookdoft 5.0, install SAP BPC 7.0 SP4 and then restore the backup of the Appset, and do the posts upgrade action of the Dimension TIME.
But in the second, what do we do??? I uninstall outlookdoft 5.0, install SAP BPC 7.0 SP4 and then what??? Do I have to restore the backup of the Appset again???
I need help.
Best regards.
Pablo Mortera.

Hello,
On the second cluster node, you have only to install the software, nothing related to the appset. If you alreay run the migration stepts for the appset, all the information are into daatbase and file server.
However, the normal behaviour is to make the installation on the both nodes, make the basic tests to validate the installation and then proceed with the appset migration.
Best regards,
Mihaela
