Web Dynpro Application Deployment need server restart?

Hi Everyone,
When deploying Web Dynpro application on production environment, do we need to restart the sap portal system and server?
I have this issue that when ever we deployed new develop Web Dynpro application with new Abap Function module we need to restart our Enterprise portal production server. Is this really necessary. Is there other way to deploy Web Dynpro application with new Abap function module without restarting the server.
Please help,
Michael Mondelo

Hi michel,
for example , assume you imported a RFC bapi_flights from r/3 to webdynpro dc , and both rfc requests and webdynpro application is deployed to the development server and then moved to quality server.
now you have done some changes in the rfc bapi_flights i mean change in the structure .
case 1 : now with out reimporting the change to webdynpro application and you move the request to the quality r/3, your application dumps . because the structure change is not incorporated at your webdynpro DC.
case 2 : you have re imported the rfc incorporating the changes to the web dynpro applicaiton dc, now with out moving the structure changes request to the quality r/3 and you deploy the webdynpro Dc having the changes to your quality EP , still the applicaiton dumps because your appliction refers to the rfc with out structure change in quality r/3.
case 3 : you have moved the abap request having the strucutre change and also the webdynpro development component where the changes are also incorporated , now on moving both , your application might dump , because the meta data cache might have been not updated with the new structure change in the quality ep server. so you have invalidate the cache in the JCos you have used to import the rfc. or else on restarting the EP server , the new structure change will be updated in the server.
most of the cases Invalidation of cache works and in some cases you have restart the server fo the changes to update.

Hi jitender,
I've installed the same version.
After configuring the Netweaver Developer Studio (+ searching for the config) and trying to deploy a webdynpro application I was asked for an SDM password (which should be the default password from the install "abcd1234" unless you've changed it of course)
After entering it I was able to deploy it.
In other words can you check if your config settings in the Netweaver Developer Studio are correct? I cannot check now unfortunantly.

The Web Dynpro application 'UWL' has expired

Hi ALL,
We are using Enterprise portal 7.0. and backend SRM server
When the user login into portal it will take him to the UWL page
in that the user click for any "Approve shopping cart" the error message showing
" The web dynpro application *'UWL' has expired. restart the application. choose 'refresh' in the iview tray or use the*
*browser 'refresh' button to restart the iview"*
user not getting the error message every time. error coming occasionally
we suggest the user to clear the cookies and restart the browser and relogin.
but some times it works some times not
Can any one know the exact problem (any parameters has to be change or any other solution)?

Dear Abdul ,
Hope you are doing good.
We have seen similar cases of WD Session Expired error message when the jsessionid cookie issued by the server with the initial requests was not returned from the client with subsequent requets to the server. The only way to ascertain whether this is the case in your system will be by checking the HTTP watch trace (note 1558903 - How To Trace a Portal Scenario Using HttpWatch).
As the jsessionid cookie is used for session management, when it is missing from the request headers the correct session could not be retrieved and as result new session will be created for that user. Set the parameter JSESSIONID.CookieDomain to "NONE" as mentioned in the sap note: 791765 and see if the issue persists. This configuration should be accessible in
Config Tool -> expand the tree "cluster-data" -> "Global Server Configuration" -> "services" -> "servlet_jsp" -> Go to "Global
Properties". Do make the changes, save the customization and then restart the complete SAP server (not just the JAVA server nodes).
Kindly go through the note completely.
Also make sure that the SystemCookiesDataProtection and SystemCookieHTTPProtection is set in the HTTP Provider Service on
the server nodes.
Do make the changes,save the customization and then restart the complete SAP server.
Thank you and have a nice day :).

Web Dynpro application needs to never expire.

Hi
I have a Web Dynpro application (NW2004 SP12) that displays spreadsheet like sales data to anyone who walks past the screen in a common area in the office/s. It should therefore run unattended. It refreshes the data on a timer. The data comes from a back-end aRFC. Everything works fine but about every 1.5 days the application times out (session expires) and needs to be re-opened (this seems to be a large administrative problem to re-login at all the deployment sites).
It gives an error 500application has expired. Please restart with the refresh button
In testing/troubleshooting I used the direct URL to the application running on WAS and not through a Portal iView.
I also changed the System destination from using SSO to using a dedicated user to the back-end.
Does anyone have an idea on how to auto refresh a Web Dynpro application or auto-renew the session so that it can run forever or a way to re-login automatically?
Thanks in advance,
Rick Viljoen

Hi Isidro
Yes, this was my final solution. Here is the code for the htm page. It will refresh/reload every 6 hours. Hope it helps.

Cannot deploy web dynpro applications

I would be appreciate if anybody could help me with this issue.

At the same time if more users are deploying then you may such 'deployment aborted' errors check if there are more child instances for the J2EE engine.If not ask your basis administrator to create more child nodes to balance the load on the server instance.Also You can find out the server details at
"http:
<hostname:portnum>\index.html"select system configuration-you can get the details of the SDM and the j2ee engine from there.You need to have proper credentials to get the information from the above url.
Provide those details in the NWDS.

Amr Azim,
You must have logged in thru a dedicated connection to any server through say VPN before deploying.This way the sdm uses the same login as that of already establised connection.
So 'sign of' all connections to any servers before deploying and redeploy your application.Here you will be prompted to supply the sdm password and deployment shall proceed.

Error while deploying the Web Dynpro application

HI All,
I have developed a Web dynpro application. Now when I am deploying the application I am getting an error.

Hi Neha,
It seems that there is problem with your SDM server. It seems that during J2EE engine configuration SDM server is not configured. Actually this configuration is done by Basis Team.
By the way try out your Server setting:
Go To:: Windows -> Preferences -> SAP J2EE Engine
[Mention the required details over there]
And Check whether you are getting Active SDM Server under J2EE Engine.

Problem of Creating a web dynpro application based on a car rental web serv

Based original SAP developer studio examples shipped with the developer studio, I first create J2EE application QuickCarRental. It works at http://192.168.254.4:50300/QuickCarRental.
A web service QuickCarRentalWebService is defined in J2EE application QuickCarRental. My web dynpro application TutWD_CarRental is web service consumer invoking QuickCarRentalWebService.
When I deploy TutWD_CarRental on SAP J2EE engine and run the application at http://192.168.254.4:50300/webdynpro/dispatcher/local/TutWD_CarRental/CarRentalApp, i can see the web dynpro web application interface right.
however, I get the following error when I input some data and Click button rent a car.
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (404) Not Found.
when i click Display all bookings, the error is:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (404) Not Found.
I install SAP developer studio on my winXP desktop, and the SAP developer studio version is 2.0.10.
I have my SAP Web application server and J2EE engine Version 6.40 run on a different machine. the SAP server IP address is 192.168.254.4
could anybody give me some clue on this. is that because i miss some configurations on SAP server for enabling web services of QuickCarRentalWebService?
Thanks!

Problem deploying Web Dynpro Application Definition

Hi,
I have written a Web Dynpro and then deployed it to an EP6 NW04 server without first defining the Web Dynpro Application (silly me, I know - how could I do such a thing?). Anyway, afterwards, I created the Web Dynpro Application definition, but no matter how many times I redeploy, it does not add it to the Web Dynpro now sitting on the server.
Können Sie mir bitte helfen?
Martin

HTTP 500 internal server error while starting abap web dynpro application

Hi there,
i have some problems concerning my web dynpro abap configurations in the system. When i start an application the browser appears and displays the http 500 internal server error. The required icf nodes are activated, as far as i know. the following properties are set:
hostname: aet
port: 8000
The generated url for the web dynpro application looks as follows:
http://aet.ls3001:8000/sap/bc/webdynpro/sap/zwdr_test?sap-language=EN
Maybe anybody of you out there has an idea for that situation.
Thanks for your afford and kind regards,
Albert

Hi Ulli,
the error message says:
UNKNOWN HOST
Description: Unable to locate the server named "aet.ls3001" --- the server does not have a DNS entry. Perhaps there is a misspelling in the server name, or the server no longer exists. Double-check the name and try again.
So the problem is the hostname.
When i replace the hostname with the ip of the server, the following error occures:
COULD NOT CONNECT
Description: Could not connect to the server "10.18.187.9".
But with SAPLogon, its possible to connect on the server by filling in the ip adress.
Kind regards,
Albert
