Portal Webdynpro over SAP WebDispatcher with ShortURL

Dear @all,
we have configured the Portal to ShortURL=True. For a specific role I have now a Hash Key in the short URL table, but If I call an iView from this role the Portal will not call the short ULR, what could be wrong?

I thought it should be like that:
http://sapportal.customer.tld:<port>/987e78da595b88cea13f23017c7228c7...

I think you are supposed to use the below link:
http://WEBDISPATCHER:PORT/irj/portal?NavigationTarget=navurl://SHORTURL
i.e.,
http://WEBDISPATCHER:PORT/irj/portal?NavigationTarget=navurl://b3d6d9ebac16a46574d62757803b05d4

SAP WebDispatcher with NW7.0 Double-Stack-ABAP/J2EE

Hi folks,
we have an Double Stack NW 7.0 ABAP/J2EE System running, for using ABAP WebDynpros over Portal 6.0. On the portalserver itself the Portal and the Webdynpros are running and working absoultely fine.
While configuring SAP WebDispatcher to bring the Portal to the outside world, we
experienced some problems.
Details:
We use Webdispatcher to decrypt SSL
- HTTPS: Internet -> WebDisp
- HTTP: WebDisp. -> Portal
(this works!)
The external domain is https://portal.my-customer.de
The internal hostname of the portal is portal.mycustomer.de.
Problem:
When using the ABAP-Message Server in the WebDispatcher profile (like recommended I think), the Webdynpros are available but we cannot reach the portal.
- WORKS: https://portal.my-customer.de/sap/bc/webdynpros/sap/zmy_webdynpro
- DOESNOT: https://portal.my-customer.de/irj/portal
rdisp/mshost = portal.mycustomer.de
ms/http_port = 8100
When using the J2EE-Message-Server in the WebDispatcher profile the portal is
available but the webdynpros does not work appropriately, cause they are not reached.
- DOESNOT: https://portal.my-customer.de/sap/bc/webdynpros/sap/zmy_webdynpro
- WORKS: https://portal.my-customer.de/irj/portal
- DOESNOT: WebDynpros in portal are not available and there occurs a http-timeout in the content area with: http://portal.mycustomer.de:8000/sap/bc/webdynpro/sap/zmy_webdynpro cannot be found
Of course this address cannot be retrieved over webdispatcher, it is the "internal"
one, between webdispatcher and portal, not the external one between client and
webdisp.
rdisp/mshost = portal.mycustomer.de
ms/http_port = 8101
So the questions are:
1) Which message server do I have to use? (ABAP/J2EE)
2) How to achieve to reach both stacks?
or
When it is not possible and I have to choose reaching J2EE-Stack (Portal from outside) how can I use the ABAP WebDynpros appropriately inside the portal?
Hopes somebody can bring some light into the darkness.
Best regards
Volker

Ok the ICM logg of the ABAP-Portal shows the following.
I'm not so used to read the logs, but what I see is, that the Request comes to the portal and ist handled the common HTTP-Handlerm, but the J2EE-Handler returns a "empty" request?
Here is a part of the log:
The Request Starts, the Cache Handler is calles, the J2EE Handler is called, return of Empty-HTTP but I cannot see a "Failure".
Thanks for having a look,
Best regards,
Volker

Use sap webdispatcher with multiple hosts

I need to support 2 different senerios with our SAP Webdispatcher. I need to have some users accessing services on our backend ECC system using SSL between the SAP Web Dispatcher and the client. I have another group of users that need to use a different URL that does not need to use SSL. Do I need to run 2 separate instances of SAP Webdispatcher or can I configue one to handle both accesses?

Are all the users accessing the same back end system? If they are, you should be able to do it with one dispatcher. You would just need to configure two ports in the <SID>_Wxx_hostname profile, e.g.:
icm/server_port_0 = PROT=HTTP,PORT=80
icm/server_port_1 = PROT=ROUTER,PORT=443
This will route users to who connect to the web dispatcher on port 80 to the backend system via HTTP, and users who connect to the web dispatcher on port 443 will be routed to the backend system via HTTPS (Using end-to-end ssl).
If you're trying to route users to different back end systems, I think you will need multiple web dispatchers. As far as I know, a web dispatcher will only load balance users over a single system. But I'm not 100% on that, so maybe somebody else knows for sure.
Hope this helps,
Glenn

Webdynpro Vs SAP GUI

Hi,
Our requirement is to make SAP transactions available over internet.We are considering below two options.
1) SAP GUI using VPN
2) Portal with java webdynpro
If we are not really interested in initutive UI , whay do we need to consider weebDypro as SAP GUI is the proven technology.
WebDynpro is considerably slower than SAP GUI, What is the need for using webDynpro over SAP GUI.
We have requirements for RF enabled trasactions.How simple to develop weebdypro applications for RF enabled devices.
Please explain How webdynpro is better than SAP GUI via VPN considering the above scenario ?
Thanks,
Abdul Raheem S

Hi,
1)The SAP GUI for HTML is used in combination with the ITS technology. It runs inplace in the browser. The contents are generated by the Internet Transaction Server (ITS). The SAP GUI for HTML need not be installed separately on the client computers.
2)SAP GUI for JAVA: This GUI runs as Java applet inplace in the browser
You must provide users with the SAP GUI for Java on the Web server and edit the properties in service file Transaction_Configuration. To do so follow this link
http://help.sap.com/saphelp_nw70/helpdata/en/b7/17c43b6312210fe10000000a11402f/content.htm
3)SAP gui for windows: SAP GUI for Windows must be installed locally on the client. It is started in the browser

Advantages of EP over SAP BI Web Reporting

Dear Experts
Can you please share your inputs on Advantages of EP over SAP BI Web Reporting?
Appreciate if you could share any presentations or documents on this.
Thank you in advance.
Best Regards
PKC

Hi,
They are absolutely different environments. With EP, you can develop WebDynpro Applications, using ABAP or Java, integrate Internet Service, develop applications with Visual Composer, ... It's much more than a reporting environment. You can integrate BI reports on EP, using iviews portal components.
Look these threads:

SAP Webdispatcher :Images are not displayed after using the URL filtering

Hello,
I have installed the SAP webdispatcher 7.3 on Linux redhat 5.4 in front of the Portal 7.3.
I wanted to restrict the access just for the IRJ prefix so for this i used the parameter wdisp/permission_table = PermFile
with Permfile as follows:
#Denial of the useradmin URL from the WebDispatcher
P /irj*
P /irj/*
The filtering is working well except that for IRJ the images are not displayed so i was using so i added the following line to disply the images to the logon page
icm/HTTP/auth_
P /logon_ui_resources/*
P /logon_ui_resources*
but i still have the same issue for the irj page where no icons are displayed and i can do nothing.
The same issue also happened when using the icm/HTTP/auth_xx
Do you have an idea how to deal with this issue?
Thanks in advance;
Hassan

Hello,

P /logon_ui_resources*
P /AFPServlet/*

ABAP(R3) call to Portal(Webdynpro)

Hi experts,
I have a requirement to initiate a call from an ABAP program on R3 to a standard Portal (Webdynpro) API. Does anyone have any experience with this?
I understand that normally Portal (Webdynpro) applications will make the RFC call to ABAP via the established JCO connection. However there's very limited literature elaborating how the call can be made in the other direction i.e. from ABAP R3 to Portal
Anyone, please kindly advise how, if this can be done. Many thanks!
Best regards,
Lionel

How to integrate WebDynpro for ABAP application with SAPEnterprisePortal7.0

Hi WebDynpro for ABAP Experts,
We developed an WebDynpro for ABAP application on R/3, and now we are planning to show this as an iview on SAP Portal EP7.0 (SAP j2EE Engine--Java stack). is it possible to integrate this application with portal?
If so can you proviode me the way how can we achieve this?
ADV Thanks
Regards
Phani

Hi Alex,
Thanks for your response.
I already created the system object R/3 Backend.
Actually some WebDynpro java applications/iViews are currently running on Portal. and the developers developed these in NWDS and deployed the .sca files on the Portal server and we created Webdynpro for java iViews.
but now the requirement is creation of webDynpro for ABAP views.
The developers developed WebDynpro for ABAP on the R/3 system. So what are the parameter values we need to give at teh time of creation of WebDynpro for ABAP iview like the Namespace, Application name etc which are mandatory values and how the Portal server detects the application, this means no need to deploy the application on the Portal server?
Shall we need to maintain any JCo Destinations or not?
Pl share your ideas.
ADV Thanks

Phani

Webdispatcher with load-balancing and local icm configuration

Dear all,
we have a webdispatcher in place to load-balance the requests to our three application servers (ABAP). The webdispatcher has a hostname that is resolved by the DNS. The application servers use local hostnames that can't be resolved in our infrastructure at the moment.
That configuration works fine for all requests that reach the infrastructure from outside.
But, if a user logs on with SAP GUI and then calls a web transaction like a webdynpro, the browser opens with the local application server hostname. However that hostname can't be resolved.
Is it possible to change the three local icm configurations in a way that all local generated web requests refers to the webdispatcher too? What is the preferred configuration for this more or less usual scenario?
Thanks in advance,
Daniel

Hello,
In your scenario, I would try to create entries in table HTTPURLLOC. After that the 3 app servers should generate URLs using the SAP Web Dispatcher.

Portal themes for SAP GUI for HTML

Dear SDNs,
We have a portal theme designed with good and look and feel, but most of our applications are SAP Transaction iViews for HTML GUI. can we apply the same theme to HTML GUI applications? or at least can we change the background color and windows color of HTML GUI applications?
I have tried with ITS Theme generator, but it is just showing the tabs and others as image we need to change. Please provide inputs if any of you having the related information.
Can we also change the GUI for WIndows colors for multiple users? i know to change for one user's local layout, but how can we make one cusotm color for all the users.
Your inputs will be appreciated,
Thanks in advance,
Lakshmi.

Hi
I think we cannot apply Portal themes for SAP Transaction Iviews. However, there is a property called Stylesheet for each iview. Play with that property and let me know. The success rate is 50:50.
But I would recommend to migrate them to webdynpro ABAP. Do not still recide in 1995. Come and enjoy the 2010 Web2.0 look and feel and enhanced usability of Webdynpro.

Chiranjeevi.

SAP webdispatcher as reverse proxy

I'm using SAPNW7.3 based web dispatcher.
I would like to know if it is possible to configure webdispatcher as reverse proxy with stateful applications...
In my landscape,
<client browser> --> <webdispatcher as reverse proxy> (say, A & B) --> <webdispatcher as load balancer> (say, C&D) --> <sap EP server x4> (say, W,X,Y,Z)
A&B operate on separate servers in parallel provide reverse proxy functionality... so do C&D for load balancing.
I have configured system C&D to connect to SAP EP by using profile parameter wdisp/system_1. I want to know how to configure A or B,
IMO, in System A
wdisp/system_1 = SID=EXT, EXTSRV=http://A:8000;http://B:8000, SRCSRV=*:8093
This sends all requests (u201Cround robinu201D) arriving in port 8093 on to the two servers C&D and thereby to EP app servers W,X,Y,Z.
In this case, we can't use stateful request as per http://help.sap.com/saphelp_nw73/helpdata/en/48/957c6494cc73eae10000000a42189b/frameset.htm
Is there any other way to configure A&B, to allow operating stateful connections. If not, does this mean that sap webdispatcher cannot be used as reverse proxy unless you are using only stateless requests (without stickiness)?

SAP Webdispatcher and EP

I have two sap webdispatchers (parallel operation) and one EP (with 4 app servers) and ECC (with 4 app servers) in landscape
Client --> reverse proxy (also webdispatcher) --> webdispatcher 1or2 (load balancing) --> EP --> backend
The scenario is that user will call the portal URL through the web dispatcher which will trigger a request in ECC system. I would like to confirm if wdisp/system_<xx> should be configured in Webdispatcher.
Do I need to configure another web dispatcher between EP and ECC system for loadbalancing of requests that are sent to ECC system ?
Thanks,

Hi,
If we have multiple app servers for an SAP system, we'll have multiple ICMs for one sap system... ? Pl. correct if this is wrong.
You, the basis admin, decides to activate the ICM (or not) on each instances (CI or DIA) with parameter rdisp/start_icman.
The most common configuration is to put the parameter in the DEFAULT profile to start the ICM on each instance
In such case, will our incoming HTTP request come through message server ? Can MS do load balancing between ICM's as well ?
MS can do http load balancing but it is not a good practice because it uses http redirects and does not hide the app servers from the user browser.
Lastly, if we have one sap webdispatcher interfacing ERP and EP system both (say, total of four ICM.. two each), how will the dispatcher decide if an incoming request, is for BSP running at ERP server or a portal page at EP ?
To use the same web dispatcher for 2 different systems, you need at least release 7.2 and you have to configure it to choose the back end system. One possibility is for exmple to use a URL prefix.
All of these informations is explained in details in help.sap.com...

Olivier
