Hi Murtuza,
I have done it.
Reload means I closed and opened the project
but still i get the error
this time it also says negative cache
The initial exception that caused the request to fail, was:
java.lang.ClassNotFoundException: helloworld.wdp.InternalHelloworld Found in negative cache -

Hi,
Add additional info including the ST22 dump for security you can run find and replace in the st22 dump text and relplace ahost name and sid.
Also when do you get this dump exactly i.e. what are you doing or how are you accessing the webdynpro for the error to be generated.
What is your system patch and kernel levels.
Please provide more information otherwise this is just a guessing game.

Navigation Error in Web Dynpro Application

Hi All,
I developed a web dynpro application with 2 views.
I implemented the navigation paths(in and outbound plugs). I have a Next button in the first view and when
I clicked the next button it opened the second view.
It was working fine until, i created custom controller
and defined model node and model binding by calling RFC.
In the first view, i created a model node corresponding to the custom controller model node and defined the context mapping between the first view and the custom controller.
When I run the application (the first view displays data calling RFC) once I clicked the next button i got this error message.

Hi
Are you having any inputfields in your next view?If yes then check if you have bound the context attribute to it.
I think you haven't done that.

Deployment error for Web Dynpro application

Hello, I have developed a new Web Dynpro Welcome application in my local system, which is my laptop. I have both the NW Dev Studio and the app server on my laptop.
When I try to deploy and run the application I get the below error. As far I am concerned I have logged in as j2eadm user and trying to deploy.

Error When Duplicating Consolidation Applications as Deployed Applications

Hi All:
When I duplicate a consolidation application as a deployed one, the following error happen:
PLEASE HELP!
10-13-2011 10:16:54 : Error : Failed to create destination database connection while validating tablespaces.
10-13-2011 10:16:54 : Error : ValidateDB2TablespaceSelections : Exception : Failed to validate destination tablespaces! (-2147467259)(ORA-12154: TNS:could not resolve the connect identifier specified)
10-13-2011 10:16:54 : Warning : One or more errors occurred while trying to validate the destination tablespaces. Errors may occur during copy procedure.
But When I duplicate a consolidation application as a new one, successed.
Then deploy the application,also successed.

After digging in the tech reference I found a solution of copying a creating an ASO DB as another ASO DB using MaxL. More than that, you can even convert a BSO to ASO using the same method. here is the MaxL script:
login $1 $2;
spool on to 'maxl_log.txt';
create or replace application Sample2 using aggregate_storage
comment 'aggregate storage version of Sample';
create database Sample2.Basic2
comment 'aggregate storage version of Sample Basic';
create or replace outline on aggregate_storage database Sample2.Basic2
as outline on database sample.basic;
alter database Sample2.Basic2 initialize load buffer with buffer_id 1;
import database Sample2.Basic2 data
from server data_file 'c:\\hyperion\\essbase\\app\\Sample2\\Basic2\\calcdat.txt'
to load_buffer with buffer_id 1
on error abort;
import database Sample2.Basic2 data from load_buffer with buffer_id 1;
execute aggregate process on database Sample2.Basic2
stopping when total_size exceeds 1.9;
spool off;
logout;

The Web Dynpro application 'PageBuilder' has expired

Hi Alll,
We are implementing ESS/MSS and the Portal was working fine.
We set it up for SSL/https and it was working just fine. However when we call it from reverse proxy server the web dynro applications through the following error:
The Web Dynpro application 'PageBuilder' has expired. Restart the application. Choose 'Refresh' in the iView tray or use the browser 'Refresh' button to restart the iView
Details: No details available
When I tested this with a transaction iview they work just. Also when tested directly from Portal they work fine.
Can anyone assist on this please?
Thanks,
Mike

Hello Mike,
After a user is logged in and requested an ESS/MSS application. The pagebuilder service is requested to built the page.
When the user is still logged in but is not working with this application the pagebuilder receives a timeout after a while and the session is expired. The pagebuilder has sometimes the status stopped, you can see this in the Netweaver Administrator. (Search for the pb in the application area)
If an other user is requesting an application the pb service is started again and the page built again.
If you want to get rid of the warning you could set the "timeout" parameter to a higher value in the configtool.
Kind regards,
Marcel

Default expiry time of a webdypro is 3600 sec.Try to increase it in the visual j2ee admin tool.

The Web Dynpro Application 'PcrApplication' has expired.

Hi,
I am getting below error:-
500 Internal Server Error:
The Web Dynpro Application 'PcrApplication' has expired. Please restart the application either with the refresh button or click the following link PcrApplication.
Can anyone help me on this.
Best regards
Ali

Hi Rali,
I think you have not been using this application from long time. So the Portal session time must have expired. Well, Let us know if the problem persist even after RESTART of the browser.

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.
Description
Jan 8, 2008 2:14:12 PM /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] ERROR:
[002]Deployment aborted
Deployment exception : Cannot determine sdm host (is empty). Please configure your engine/sdm correctly !
Can any one please help me regarding this.
Regards
Neha

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.

Nittin Garg
