Using Development Components in WebDynpro components - runtime failures

Hi folks,
I developed a couple of webdynpro components and those are working fine. As I found out that I had some common functionality ( for example tablesorter class) in there I decided to get that into a common java component that would be "used" by my other webdynpro components.
Also that works fine as I have build a java component with corresponding public interfaces, attached the java component to the webdynpro components, uses the java classes in there, I can build the webdynpro components without any issues, ...
But at runtime I get an exception telling me that basically the common class definitions cannot be found ...
This is what I did :
(1) Created a JAVA DC with a package with the common classes
(2) Defined 2 public interfaces - API and Assembly
(3) Created a J2EE Service Libary, added the JAVA DC Assembly Interface and build/deployed it ... No deployment issues. ( Also tried the same with "An external library" DC when the first one didn't work )
(4) Added a reference in the WebDynpro DC towards the API public interface ( buildtime ) and to the Assembly public interface ( RunTime ) (-> not sure that one was necessary ). The DC builds without any issues.
(5) I run the WD application and get a dump ...
Any ideas what I forgot or suggestions on solving this ?
Thanks,
Steven

Thanks for your suggestions guys ...
I deployed the libary JAR seperately with the J2EE Library DC ... that worked fine according to the deployment logs.
And yes I referenced the project as well in the project configuration but that didn't do alot I am afraid ...
I did some reading up about JAVA class loaders within J2EE and it seems that by default each J2EE application ( I assume Webdynpro is one as well ) will have a dedicated class loader which only loads the classes needed within the application ( plus the default ones ). It seems that my library is not considered to be part of the application ... although by creating the link to the public interfaces I would assume it is ...
Only other thing to remark is that all the components are developed as 'local components' ... I cannot imagine that would have anything to do with it ?

How to use "used webdynpro components" in nwds 7.0

hi all,
I am using NWDS 7.0 SP8 version. I want to use my local DC1 in my local DC2. I have created public part of DC1 and integrated it into DC2 as used DC. But when I try to add the webdynpro component from the Used Webdynpro Components of DC2, I am not able to view the DC1component. Plz let me know the procedures that I need to follow to fix this issue.
Regards,
Athulya.

hi
i will mention the steps that I have done for the same.
1. Create DC1- LocalDevelopmentdc1sap.com
    . Create PP(Provides an API)->PP_DC1
    . Webdynpro Component->DC1Comp->Add as Source
    . Finish
    . Rebuild
    . Deploy
2. Create DC2- LocalDevelopmentdc2sap.com
    . Right Click Used Dc's- Selected PP_DC1(Build, Run)
    . Finish
    . DC->Build
    . Right Click Used Webdynpro Components->Add Webdynpro Component->
                                                                   Browse->Can find only DC2Comp....
Plz correct me if I have done something wrong.

DCs being removed from 'Used WebDynpro Components' list

Hi,
I am having a problem while creating a project from an already activated DC. The DC uses 6 other DCs and was built properly, activated and deployed from a client machine. Now I need to have this DC in my machine (also a client). So I made sure the DC is built & synced properly and proceeded with the project creation from the inactive DC.
The DC is getting created in my machine, but the Used DCs, though being shown properly in the 'Used DCs' List is missing from the 'Used WebDynpro Components'. And if I try to add a new DC under the 'Used WD Comp' list or edit the component usage of an existing DC, the added DCs are not available for selection.
<a href="http://img85.imageshack.us/my.php?image=dcerror1ac.gif">Error Screenshot</a>
I have tried removing and adding the DCs from 'Used DCs' list, reopened the project, restarted the NDS, did a sync, but nothing could help me to resolve this.
Could someone kindly help me to resolve this ?
Thanks in advance,
Regards,
Nibu.

Hi Pran,
As you already know now, the problem has been resolved :). But for the benefit of others like me let me put down what happened:
On seeing Pran's reply, Since he is an acquaintance of mine, I called him up & explained my problem.
As per his advice, I checked the DTR and found that the entire DC structure has been added there. But from him I could learn that only the following folders/files should be in DTR:
- cfg
- def
- Meta-Inf
- Model Folder
- src
- test
- .dcdef file
Therefore, the rest of the folders/files were deleted and the activity was checked-in. This resolved the problem and all the missing DCs were being shown again.
Pran, Thanks a lot for your help.
Best Regards,
Nibu.

About 'used webdynpro components'

Hi Gurus,
I was testing a sample application to use webdynpro componentisation.
Situation:
   Project 1:
     Component 1.1
   Project 2:
    Component 2.1
I need to reuse the Component 1.1 in component 2.1
So I added component 1.1 to Project1's public part(eg: com11_PP)
Then I added the same (com11_PP) to project2's Used DC.
after that when I tried add it in component2.1's 'used webdynprocomponents',
it is not avilable there.
Whether i am missing anything?
Thanks in advance,
         Sree

The dependency type: i selected Design Time,Build Time,Deploy Time.
After creating each project I build & Deployed.
Only after i added the dependency.
I rebuilded again.
When tested the same senario in one project,
Project1,
   Component1.1
   Component1.2
then tried 'used webdynpro components'
Its working fine.
But if both components are in diff projects, Its not working.
anyone can elaborate the process happening inside framework?
In which all files it will update internally.
Thanks,
Sree

Error Deploying ESS/MSS ERP2005 WebDynpro Components for SP7

Hi,
I have been in process of trying to Patch up the J2EE stack in an attempt to turn on SAP Delivered Solution for ESS/MSS.
We are on EP7 with ECC6 Backend.
What I have done so far::
1. Updated J2EE with Netweaver SP stack 11.
2. Imported the business package for ESS/MSS into EP. I can confirm that the content is now available on PCD.
3. Then i tried to upload the WebDynpro Components for ESS/MSS. Files are PCUI_GP, ESS and MSS. they all have a named reference to 600 SP7. These are the ones available to download for self-services from mySAPERP components on service market place.
This step is now falling over. Deployment of these components fail when its trying to deploy the application component. I must add that once we loaded the Business packages for ESS/MSS (step 2), i then checked the delivered content and created a delta link to the AU/Address iView into my own content folder. I am not sure if this has anything to do with the Failure of deployment but this is the only thing that i did in between steps 2 and step 3.
I didn't think that it would have caused any issue as this was an iview while the component its trying to deploy is a webdynpro application, but i am not sure now.
Please see the trace below.

Hi Friends,
I got the same problem but not on ESS/MSS component. But the exception was exactly the same. The solution what i found is
1. Find the exception in the Default trace. By searching for DC Name.
2. Here you should find the one in which its mentioned below error
com.sap.tc.webdynpro.repository.RepositoryRuntimeException: Failed to deploy the file '/usr/sap/EPD/JC35/j2ee/cluster/server0/./temp/webdynpro/public/burton.com/portal~passwordchange/webdynpro/Components/com.burton.webshop.b2b.myprofile.EditPassword/EditPassword.xml' into the database. Reason: Development Object 'local/wdMyProfile' contains already same repository content. Hint: fully qualified name of the repository VMO must be globally unique.
3. Now go to the visual administrator -> deploy -> webdynpro and undeploy the local webdynpro with which the current DC is conflicting. (You should decide whehter you can undeploy or not)
4. Now try activate the activity or Deploy the DC you shouldnt get the problem.
Actually i got this problem when i created a WebDynpro DC by importing the local webdynpro project. So, when i try to activate the activity of DC created then its not getting deployed. When i check the logs, i had same exceptions as you ppl got. So after going thru default trace then i figured out that the local webdynpro is the reason for this conflicting. Then i undeployed that webynpro.
Hope this may be useful for you and others...
Thanks,

Webdynpro components integration procedure

Hi, Any Body give me the suggestion, how to integrate the diffrent components into the one project.Like Each programmer creating their own project under project different webdynpro component created. Finally , to integrate all the component in one one project from different project. Plz give the solution how to integrate .
My basic question is , what is the procedure to follow to integrate the webdynpro components in one project.

If in the case you have not created the DCs and proceeded with simple web dynpro projects, you can copy individual components in single project. There you can use used webdynpro components concept and have data exchange using interface controller.
A lot of efforts are required for this in case you modify the components, as you need to copy the inner components again and again!
Ideally in case of team development you should use JDI. Please follow scenario 2+ for the same.

Hi,
Iam using the MDM webdynpro components. I have created a MDM destination which has authentication as "No Authentication", then the repository and server name.
I have added the IP address of the CE portal in the allow.ip file.
But when i create a project under the MDM WD CONFIGURATOR and try to use the destination i get an error

Calling Dynpro components in Webdynpro ABAP.

Hi friends,
Could anyone tell me how to call webdynpro components in DC's in Webdynpro ABAP.
Regards
Sireesha.

Hi Sireesha,
In WebDynpro(WD) ABAP, we do not have DC methodology. We can save the WD components and appliations in package. We can call WD applications using
1. OBN
2. if it is embeded in portal, then we can use portal navigation
3. We can also reuse the WD component in another WD component, by component reusability concept.
Best regards,
Suresh

How to preview standard MDM Webdynpro Components ?

Hi
As we know, we can create standard MDM Webdynpro components from CE 7.1 SP 04 onwards.
Suppose I have created a project using MDM WD configurator and added a search component, a resultset component and an itemdetails component. We can preview the individual components using the preview button provided in the configurator. But in order to see the consolidated project containing all the 3 components, we need to embed them as used components in a custom WD component. Then through the custom WD component we can preview the 3 standard components.
My question is, is there any way in which we an preview all the 3 standard MDM WD components together without putting them in a custom WD component ?
Is there a way we can directly assign an iview to a project created with MDM WD configurator ?
Thanks
Sayan Ghosh

Found the sloution. Can be launched in the browser with the following url giving the component details :
http://<hostName>:<portNumber>/webdynpro/dispatcher/sap.com/tcmdmwdcompsmasterwd/MASTER?proj=<Project_Name>&rs=<ResultSet_Name>&s=<Search_Name>id=<ItemDetails_Name>

Webdynpro components within SRM

Hello all
I want to access the webdynpro components within SRM Portal . How do I do that?

Hi,
> 1. Is it necessary to deploy webdynpro components SAP

PCUI_GP is mandatory for both ESS and MSS,..
So , if its ESS .. ESS 600 and PCUI_GP 600 should do.

You can check this in SDM. ess~component names..

You will only have the webdynpro iviews in portal,, but the actual webdynpro application these iviews use wont be there.. So it wont work.

Therefore to identify which webdynpro components is firing plug to WD1 i have created one value attribute in interface controller of WD1 , and mapping tht attribute to views which are going to fire plug for WD1. But when i m firing plug aftr setting value to tht attribute i mfetting unknown context exception error at line which issetting value to tht value attribute.

Hi Manoj,
1) Go through the following link to check whether you are following all the steps required to be able to communicate between 2 components:
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/60132577-7801-2b10-c9b1-b13b2f78f23b
2) Check whether there is no change in the model structure at the backend.
3) The problem can also be due to incorrect mapping.
4) Check you have added all the jars as told here:

Enhancing standard webdynpro components

Hi Experts,
I need to change the layout of the standard web dynpro components. I started enhancing the relevant methods in the component controller with pre, post and overwrite methods but when it comesto the UI, after enhancing the componenet if i go to the enhancement to change the UI it is changing the standard UI. In my case the requirement is grouping the UI elements on the SAP standard Webdynpro components and change the format of the data on the screen.Can you please provide suggestions on how to enhance the web dynpro layout without modifying the layout? Please feel freeto askme for further info on the same.
Thanks alot inadvance,
Regards,
Ravi.

hallo Ravi,
You can delete the layout and create a new layout with the changes you needed. for example the standard UI consists a group with layout as flowlayout.
You have to delete this group and create the group with same name and change the layout to Matrix layout.

Compare two webdynpro components

Hi all
there is a webdynpro component with the name ZWDC_ONE.
i copied it by giving a new name ZWDC_TWO.
and I made few changes in the component ZWDC_TWO.
now there are two webdynpro components ZWDC_ONE and ZWDC_TWO.
i want to compare them with each other, to see what are the differences, what are new things added in ZWDC_TWO with respect to ZWDC_ONE.
for abap programs, there is a transaction SE39.
but it provides facility to compare programs, function modules, and classes, but not the web dynpro components.
is there any way we can compare two different webdynpro components.
thanks,

As far as i know there is no such tool available.

Catching events on Desktop , without using any AWT or Swing components.

How can I catch events(for eg: mouse clicks) on the Desktop? I do not want to use any AWT or Swing components in my application.
Also, i want to get events even some other java/non-java application windows are visible on desktop, as long as my application is running.

Myrequirement is to capture all AWT events, regardless of on which component its being happened.
I mean I have to capture events outside the current running application (on desktop and any other java/no-java appliation windows also).
I couldn't find any other forum which discusses about event handling.
This is part of my app. other end extensively uses awt.
