Reimport model

Hi,
I was wondering how ABAP WebDynpro handles model changes?
In Java WD, you can do something called "Reimport model", which will then regenerate the context nodes for import and export and the java representing classes of ABAP objects/ddic structures etc.
Do you need to do that in ABAP WebDynpro? Or the developer is expected to change the generated method manually?
Cheers
Michael

Elton,
Vijayakhanna is right: it is necessary to re-start server. After first model usage metadata get cached and stay in cache as long as server is running. So even you have modified model, stale metadata is returned unless you restart server.

Build ERROR after reimport model, too many datatype deleted

Hi all,
now when I reimport model of my DC, I found too many datatype would be deleted after I press Finish. I think with this deletion my dc will never pass the build. All I wonder is why this happen, what kind of operation on back end will cause this kind of deletion.
I know there must be some changes behind java layer, but I dont know why they just delete datatype, I can not continue my work with these models, they are too many, I can not fix them all or delete&recreate them.
Give me some hint?
Best Regards,
William

HI William
There might be some changes done in your Backend [exsisting model]
so it is throwing dump when you are trying to reimport. what you can do is delete the exsisting model and try to create a new model. first take the back up of the project and experiment on the dummy project

Reimport Model for JavaBean

Hi All,
Whatever I try, the option 'Reimport Model' in the context menu is disabled for my JavaBean Model.
Get's a bit anoying after having deleted the model, rebuild it, and reworked the context mappings for the gazillionst time.
Anyone any idea?
Thanks,
Jurjen

Hi Jurjen,
We too have to face same problem again and again. But following points may help you:
1. When you add any attribute to your java bean, ensure that it has proper getter and setter method. Then go to model class which is generated based on Java bean class and manually add the attribute in that model class. You can do manual addition by double clicking the specific model class, going to properties and then clicking on New. Make sure that whatever property you are adding must have same name as what you have added as attribute to your java bean.Reflect it in mappings also.
2. If you are deleting some attribute from java bean class, remove it's getter and setter also. Then again in properties of corresponding model class, delete the associated property. Reflect it in mappings also.
3. If you have to do complete re importing of java bean model classes then in most of the cases we found out that mapping from Component Controller to Bean model have to be reconstructed but not from view to Component controller. Only some addition deletion of some attributes have to be done from view to Component Controller.

Java.lang.NullPointerException while reimporting model

Hi All,
I have a Web Dynpro project that contains several models.
When I try to add a new RFC (by reimporting the model) I get java.lang.NullPointerException.
I can add the RFC to a new model without any problem but I need to add it to this specific model.

Yugandhar,
thank you for your reply. I moved my workspace to another machine with a NWDS SP01 and it works!!
I got one question. At present my NWDS and the target NWCE are both at SP 03 level.
If I change the SP level of my NWDS, must I change also the NWCE?
In other words, the NWDS and NWCE can be at a different SP level?
Thank you and best regards,
Livio.

Dont want to restart Server everytime I reimport model

Hello,
Everytime I reimport a model, I get a popup saying "Please restart your J2EE Server......" with no option to cancel it.
Any ways I can avoid this?
Regards,
Shubham

Hi Shubam,
Whenever u <b>Reimport </b>the model server <b>Restart </b>is necessary otherwise the changes will not be reflected. You will get an error when you deploy the application.There is no go around except restarting the server because after first model usage metadata gets cached and stay in the cache as long as the server is running .So, Once you restart the server the cache will be cleared.
Refer to the below thread once.

RFC doesnt show up in reimport model

Hi,
We have created a ZRFC and when reimport and add that to the model . after i give the login credentials for the ECC and search for the RFC it doesnt show up in the search. But it still exists in the system. Do I have to do anything like exposing it as service to show up in the list.
Please let me know.
Thanks,
James

Hi,
Yes, RFC should be remote enabled. Also, make sure that your server credentials are pointing to server , where RFC exists and not any other server.

NullPointer after Reimport Model

Hi,
I have reimpoert a model to add a new output-parameter. So I made a reimport. Than a DC-Build and than I edit my model binding to add the new parameter in my context.
But now I get a Nullpointer-Exception. It seems, that it makes the model-execute and the node-invalidate but there is no data in the fields.
Have I forgot something during the reimport process?

Hi,
Please reffer this error :in the portal
Hope Help full !!!

Reimport model requires server restart for version nw 04s sp15

Hi All,
Does reimport of model requires sever restart in NW 04s sp15, Sometimes it works with out restart of server. .Please give your inputs.
Thanks.

Hi,
The J2EE engine holds a cache of deployed model objects that is optimized by technical system.
Therefore if there are updates in the metadata of a deployed model object, it is necessary to restart the J2EE engine to flush this cache, and make the new interface metadata available to the Web Dynpro application.
Its not always required to restart the server.Its only required when there are updates in the model object.
Thanks n Regards,
Archana

Reimport Model after BAPI Changes

Hi,
Understand that a workaround to refresh the cache/metadata is to restart the J2EE server, after some BAPI changes and reimport the model.
Is there any solution without restarting the J2EE server?
Thank you.

Hi Vincent,
The only possible way to refresh the Metadata is to restart the J2EE server.

Hi Punit,
Follow the two things
1. Make sure that the JCO you are using is working fine.
    Check that the userid and password is still valid.
2. Check whether the RFC is working fine or any changes happened? Log in with the user same as    portal and then execute the RFC.
3. Restart your server and NWDS.
it will solve your problem.
thanks

Hi Göran
Thnks for your answer
This always has been happening, i´m thinking that this is a problem of Windows Vista Operating System, because one coworker has the same project and the same NWDS with the same SP but he has Windows XP.
I am working with Adaptive RFC Model.
I can´t logon in anyone backend system (R/3), because i can´t open de wizard reimport model...

Wrong JCO names appear in JCO refrences on model reimport

Hello All,
I have two JCO names mentioned in the JCO refrences in the properties of my DC. But As soon as I reimport model, a third JCO name which is wrong, appears in the JCO references tab of DC properties automatially. where is this JCO name coming from ?
Regards
Mrinalini

hi
check the JCO name in data dictionary in your project, to reflect the new JCO's, you must deploy it once. Also invalidate the JCO after deployment (using System adminstration).

Random model exception in WD application

Hi,
I am using NWDS CE 7.1 Ehp1.
I have 3 web dynpro DCs in which I have imported a ARFC2 model for same RFC.
This application was working fine in all three landscapes dev, test and prod.
There was a change in table type parameter in this RFC which is working fine when tested from SAP.
I re-imported this model in 2 out of 3, WD DCs and transported in dev, test and prod.
Since then I am facing following issue: -
Application works fine sometimes and sometimes it gives following exception:-
java.lang.IllegalArgumentException: Target role name 'About_Me' not defined for model class 'com.vendor.javaportal.homepage.userdetails.userdetails.Z_Empprof_Getdetails_Output'
    at com.sap.tc.cm.base.model.BaseGenericModelClass.retrieveTargetRoleInfo(BaseGenericModelClass.java:104)

    at com.sap.tc.cm.arfc2.gci.ARFC2TypedModelClass.setRelatedModelObjects(ARFC2TypedModelClass.java:199)
    ... 76 more
I did some preliminary investigations: -
1.     I initially thought about a transport problem on one of the AS but prod server has only one single AS.
2.     The RFC has been tested in SAP R3 in all application servers and is working fine.
3.     JCO connections from WD to SAP are up and running fine.
Any idea what is going wrong here?
I also tried to reimport model for two erroneous DCs and created a activity each and transported to Prod.
but still same strange behavior!
Please help.

Amey

Hi Pradeep,
Thanks for reply, but I have already re-imported the model and transported it.
Still I get this exception.
First time when I re imported the model after RFC change, it showed some deltas in re import.
I transported this activity to prod and I started getting this exception randomly.
Sometimes the application works fine but sometimes it runs into above mentioned exception.
So I re imported the model (this time it didnt show any deltas) and transported that activity to prod.
but still no success!

Broken DC after re-importing model

Hello,
I have an existing model with an RFC already present in the model. A few changes have been made to the structure of the RFC which required a re-import of the model.
After re-import, the DC becomes Broken on NWDS and also all the structures and data fields present in the model dictionary show as deleted.
Upon building the DC on local machine, I get the following error. I tried reverting and reimporting the model but was in vain.
Any leads in this direction?

Hi
First reimport model , then build it , all inconsistency will be display.
these could be possible
1 : I am sure that its a problem of some structure changes in RFC (check all those which are present at DC binded with model)
2: Dictonary are not generated (check at dictonaries , this is default taken care by framework sometimes it happen)
3. Local Context node having some type missing (due to structure change) (delete all the model binding and bind it again with new structure)
