Web Dispatcher Not forwading XML document to SAP XI

Hi Everyone,
We have a web dispatcher that is accepting an HTTP Post over SSL and forwarding this connection to our SAP XI system. Our client post to the box and we see the ssl information in the log and then a string of information about connecting to our J2EE Engine where XI resides.
Here is a snippet from the SWD log:

We checked the J2EE logs on the XI server but we do not see any activity. Is the document making to XI or is this failing in SWD?
Thanks for the help.

Hi
Did you check the connectivity i.e web dispatcher with any other system(LandScape).
For example CRM for FICO.
Thanks

Web Dispatcher not doing the load balancing on the portal

Hi Experts
I am having a production issue where the SAP web dispatcher is not doing the load balancing on the portal.

In my Web dispatcher Admin page, I see all the three application servers, however the requests are going to only 1 App server. We are using ENd to End SSL configuration for the web dispatcher.
We also have a reverse proxy in the landscape and reverse proxy is forwarding all the requests to the Web dispatcher. In Web disp Admin page>Dispatching Module>SSL End to END dispatching, I see only ONE table entry in the dispatching table and it is our Reverse Proxy.
As all the requests are coming from only one source (Reverse proxy), it seems to me that the sap web dispatcher is forwarding those to the same Application server every time.
Can anyone please advise ?
I also tried to configure logon group in NWA, the web dispatcher is detecting the logon group and all the app servers in the logon group. It still not doing the load balancing.
I would greatly appreciate any help.
Thanks
Viny

Vincent, can you please elaborate more ? Is the web dispatcher not able to recognize stateful and stateless application requests ?
I saw that the procedure for configuring SSL Termination on Web dispatcher is long and complicated and looks like SAP web dispatcher needs to have SSL certificate of its own. As we have no ABAP servers and only Java servers, I can not even create the PSEs using STRUST (as described in SAP help -http://help.sap.com/saphelp_nw70ehp1/helpdata/en/48/99c388d7c46bb9e10000000a42189d/frameset.htm
We already have SSL certificates for Java App servers.
I suppose there should be a way for web dispatcher to identify the incoming requests and forward to appropriate application servers.
Any help is much appreciated.
Thanks

AQ Adapter error: Could not create XML document carrying AQ Headers

I'm having problem with the AQ adapter (ADT) sample that comes with the SOA 10g install.
I am running 10.1.3.4 on XP, using Oracle XE.
I can use the sample sql script to enque and deque. However, when I deploy the sample ADT (BPEL project), I see errors in the opmn log. The BPEL instance is not even created.
I see another post with similar question, Re: Debugging BPEL when using Oracle AQ but no answer.
Any help is greatly appreciated. Thx!

thanks for the reply. I did look into that post, and couldn't found where to set that option either.
However, my PC was rebooted a few times today (I didn't change anything with BPEL), and I just re-ran the test now, that problem disappeared! It is working fine now.

Could not create XML document carrying AQ Headers

Hi gurus,
I’m trying to run the "Simple_XMLType_Payload" sample, and I have successfully deploy it on Oracle BPEL v10.1.3.1.0 , and after en-queue into the XMLType_Payload_In queue the recorded has been de-queued successfully, however there no instance for the BPEL has been created on the BPEL Console moreover there is no recorded inserted in XMLType_Payload_Out queue.
After investigating the OC4j_SOA log file, I found the following error

SAP Web dispatcher not forwarding incoming HTTP portal sessions.

Hello,
We are using an EP6 Portal from which Abap Web dynpros are launched. The incoming http sessions were accessing our backend ECC6 SAP system through the sap server message . The http sessions were badly dispatched between the two abap servers. We have been advised by SAP to use the sap web dispatcher instead.
The sap web dispatcher has been correctly installed and configured (on the central abap instance ).
I have carefully read the SAP help section concerning the server selection using the sap web dispatcher :
http://help.sap.com/saphelp_nw04s/helpdata/en/5f/7a343cd46acc68e10000000a114084/frameset.htm
All our settings seem to be OK :
The incoming HTTP requests are forwarded to abap servers only.
*In transaction SICF, all the services under the tree
sap/public/icf_info have been assigned to the same logon group .
The capacity of the two servers included in the logon
group " is the same :
server40 LB=12
server60 LB=12
In the Web interface, capacity equal "1" for the two servers.
wdisp/load_balancing_strategy= weighted_round_robin
In the SAP web interface, the prefered server is ALWAYS the same :
Status of Server Group "LOADIS"
Loadbalancing Information
Number of Servers in this group 2
Last used Server
Preferred next Server server40_SPA_10
But it seems that the sap web dispatcher is not used at ALL.
The Load distribution is still based on the SMLG workload as it was the case, before, with the sap message server. The information displayed in the web interface (preferred server) is wrong.
The Preferred next Server is ALWAYS server40_SPA_10 (shown in the web interface), but, in fact, the http sessions are distributed between the two servers server60_SPA_00 and server40_SPA_10 depending on the server quality diplayed in transaction smlg. It was exactly the same behaviour we had before, only with the sap server message .
Any useful help would be highly appreciated.
Best Regards.

Hi,
firstly, have you checked note 1094342? What variant do you want to use? Do you terminate a SSL connection on web dispatcher and create a new one between web dispatcher and application server? It looks like the web dispatcher can't verify SSL certificate used by application server. Maybe you've already tried this but you can try to turn off SSL between dispatcher and application server. If this setup works then problem is in SSL connection. You can check what host name is used in SSL certificate and what host name is used by dispatcher. You can use parameter wdisp/ssl_certhost which sets host name which will be used for certificate validation.
Cheers

Hello Nani,
It looks to be a SNC Issue.
just check wether you have the parameter snc/gssapi_lib define in ur profile of SAP system
This parameter should be set to the path of your gssapi32.dll file
Also u must also have a system variable defined SNC_LIB which is again to the path of gssapi32.dll
Also make sure that gssapi32.dll exists
Check these,ur web dispatcher might come up

Web dispatcher - not working

Hello guys,
we have a problem concerning our web dispatcher.
Calling
[Link to site|http://pc7.phoron.com/]
we receive "The page cannot be displayed".
The SAP Management console tells us, that the responsible web dispatcher is not working. Trying to start it with sapwebdisp pf=... everything works fine (no error message or something like that). Looking back at the console the webdisp still appears green and neither the web page nor the web administration interface is reachable.
I don't really know why?!

Client authentication in PI when SAP Web dispatcher terminates SSL

PI Security Experts,
Here is our design for Third-party Peoplesoft system initiating SOAP Call to PI Web Service created on our PI server.
1) Third-party Peoplesoft Application server initiates a SOAP call.
2) Third-party Network Gateway has a URL server certificate from our gateway and our gateway server has a root certificate from the CA used by third-party gateway. this will be used to establish the SSL tunnel between gateway.
3) SOAP request in our network will be routed through load balancer to SAP web dispatcher.
4) SAP web dispatcher terminates SSL connection
5) We will generate client cert for authentication and pass it onto third-party which they will load onto their PeopleSoft application server. SOAP call initiating from the PeopleSoft server will pass the client cert along with the message (My understanding is that the client cert will not be a part of SOAP message body. Ina other words we are not implementing message-level security. Is that true? How will the client cert be passed? How and where will a client attach the client cert with message?My understanding is that this is a network layer security and client certificate will be authenticated on PI J2ee server at SSL protocol level..Is my understanding correct?)
6) We will also load client certificate generated for client onto J2EE server using Visual Admin and map it to PI user for authentication.
7) SAP web dispatcher terminates SSL and passes the SOAP message to PI (J2EE) along with client cert in a http header variable.
There is some conflicting SAP documents. some say that client cert can't be used for PI authentication if Web Dispatcher terminates SSL connection (http://help.sap.com/saphelp_nw04s/helpdata/en/ea/301e3e6217b40be10000000a114084/frameset.htm). There is some other documents that say that authentication using client cert is possible by having J2EE trusting Web Dispatcher and by passing client cert from Web Dispatcher to J2EE in a httpheader variable (http://help.sap.com/saphelp_erp2005/helpdata/en/ea/301e3e6217b40be10000000a114084/content.htm).
Now if client cert authentication is possible even if Web dispatcher terminates SSL, what cert do we need on J2EE, a cert from Web dispatcher or a client cert that's coming in from the client appication (the one that we created and provided to our third-party)?
If we install a cert from web dispatcher on J2EE then do we need a client cert on Web dispatcher instead of on J2EE? If so how and where do we map client cert to PI User?
I will really appreciate any advise on whether we are going down the right path and any pointers to my questions.
Thanks,
Saurabh

Regarding message level you can encrypt the message using certificates.
For both of this basis team has to deploy the releavant certificates in XI ABAP Stack or Java stack.
Generally if the scenarios are intra company we dont use any transport level or message level security since the network is already secured.

Web dispatcher url Rewritting to several sap systems

Hello SAP NW Community,
we need a reverse Proxy to achieve application of different SAP System via Internet. We desided to use web Dispatcher.
The host names of sap systems should not be visible, because of this we create the following URL Rewritting rules.
For example:
AAA, BBB and CCC are sap System SIDs;
"wdisp.company.com" is the FQDN fron webdispatcher
The "icm_filter" Looks like this:
if% {HTTP_HOST} RegIMatch "wdisp.company.com"[and]
If% {PATH} RegIMatch "AAA"
RegIRewriteUrl ^/AAA/(.*) /$1 [noescape]
SetHeader x-sap-webDisp-target-sid AAA [break]
the next rules are the same but for BBB and CCC.
The idea is to rewrite in background all URLs such as:
http(s)://wdisp.company.com/AAA/...
to :
http(s)://<FQDN from AAA>/...
The result is always the same: the rewritting for AAA works fine but for BBB and CCC we get -http error 404.
The results are independent from web browser(IE or Firefox).
The http trace Tools- HttpWatch Basis or Firebug show also no rewritting for BBB und CCC.
According the documentation is web Dispatcher able to support many "stateful" and "stateless" connection to different backend sap System.
Do you have any ideas why the rewritting works only for the first sap System?
We tested with different browser and Browser sessions but the resul was the same.
BR,
Rumen

Hi,
Instead of PATH , use different pots like this, you can get the URL redirection,
icm_filter.txt :
if %{HTTP_HOST} regimatch wdhost.company.com*
SetHeader x-sap-webdisp-target-sid AAA [break]
if %{HTTP_HOST} regimatch wdhost.company.com*
SetHeader x-sap-webdisp-target-sid BBB [break]
if %{HTTP_HOST} regimatch wdhost.company.com*
SetHeader x-sap-webdisp-target-sid CCC [break]
In Instance profile :
wdisp/system_0 = SID=AAA,MSHOST= AAA.HostNane ,MSPORT=8111
wdisp/system_1 = SID=BBB,MSHOST= BBB.Hostname ,MSPORT=8100
wdisp/system_2 = SID=CCC,MSHOST= CCC.Hostname ,MSPORT=8101
URL :
http://wdhost.company.com:8111 --- goes to AAAhost and so on.

Certificate Revocation on SAP Web Dispatcher

We have recently set up X.509 Certificate based authentication. The SSL handshake is performed by the Web Dispatcher. Requests are forwarded to SAP Netwewaver 2004s Portal with the certificate in the header field. All of this works "as advertised". Certificates are created by an OpenSSL based CA with the proper extensions and are mapped to UME accounts.
Now we want add the ability to revoke certificates. One reason is, that even if a certificate is no longer mapped to an account, the Portal will still allow the user to log in and use the certificate. The certificate is not stored in the UME, but for the time of the session it looks as if the user did authenticate with a certificate.
We have added the CRL distribtion point extension ot a certificate. We can see that the CRL is downloaded from this site. It shows up in the certificate revocation service page. However, all revoked certificates still work.
The same CRL works correctly on an Apache test server. Here a revoked client certificate will already cause the SSL handshake to fail.
Does it help us to have the CRL installed to the Portal server? Or is it necessary to set up revocation on the Web Dispatcher? Does the Web Dispatcher support certificate revocation at all? If yes, where does it get the CRL from? Does the CRL have to meet certain requirements in addition to the ones defined in RFC 3280?

It will, however, allow the user to map the certificate to his account. This even seems to happen, if the CertPersisterLoginModule has been removed from the login stack. So all of a sudden the user can login with username password, and at the same time present the (invalid!) certificate to the applications...
That indeed sounds like a bug - so it was a good idea to submit a support message.
Regards, Wolfgang
PS: I still believe that certificate revocation should be customizable on a per-application level ("application" in this context refers to "usage type": the same certificate might be used for different purposes: SSO, digital signature, encryption, S/MIME, ...). Furthermore, some of the certificate revocation mechanisms have a negative performance impact so they might be used with care. Take the payment card validation as an example: depending on the purchase amount you might be prompted for an online validation (requires to enter your PIN) and sometimes you simply need to sign-off a piece of paper - the decision is up to the shop operator and depends on the related costs (for online validation) which is comparable to "performance impacts" in our case).

Error SAP Web Dispatcher

Buenas tardes estimados,
Configure el web dispatcher con solman pero el webdispatcher solo me permite acceder a los servicios del stack de java que corren en el puerto 50000 pero no me deja ver los servicios abap de la SICF que corren en el puerto 8000 alguno tendra una idea de porque ocurre esto? y como puedo solucionarlo?

Hola Diego,
Te comento si estan corriendo perfectamente mis servicios de la sicf por el puerto 8000 y los de java por el 50000 mi ms/http_port es el 8101 lo que pasa es que el web dispatcher solo me detecta el stack de java no me detecta el stack de abap por ende puedo acceder a cualquier servicio que corra en el puerto 50000 pero a los que corren en el puerto 8000 que son los de abap no le llego por el webdisp porque el mismo no me esta detectando el stack de abap.
Pude observar que al introducir esta url http://ServidorDeSolman:8101/msgserver/text/logon obtengo este resultado:

Como podemos observar solo arroja info del stack de java y los puertos java pero no arroja la info del stack de ABAP.
Tambien por el webdisp realice esta prueba via linea de comandos en el cmd:

Alguna idea de que se puede hacer?
Muchas gracias por la ayuda
