Using Java Model In Web Dynpro

Hi
I have a Java Bean. I have created a JAR file for this DC. A public Part si created for this DC and the JAr file has been added to it.
In the Web Dynpro DC, i add it in the used DCs. But when i go for Add Used Components, iam not able to see it there. And also when i am creating a model by selecting Import JavaBean Model, and selecting the Public Parts of the USed DCs Option, it gives "No Java Beans available for Import" message.
Can anyone please help in this regard, as to how the java bena model is to be used.
Thanks & regards,
Anupreet

Using EJB Model in Web Dynpro

I have to redeploy my EJB.ear (used as a Web Dynpro model) everytime the J2EE server is started (only the first time), after which My Web Dynpro program continues to work. In other words, the following code in my Command Bean is not successful without redeploying the EJB.ear for some reason. Can someone please tell me what I am doing wrong ?
home = (MyLocalHome) context.lookup("localejbs/MySessBean");

Walter, thanks for the reply. When I checked the EJB Container in VA after starting up the J2EE server, my EJB shows a blue check mark already with the START button grayed out (STOP button is active). So I would think the EJB is started already... HOWEVER, I noticed that when I hit the DEPLOY button there, I see a warning message popping up which says : "This Application hasn't J2EE modules, so it cannot be loaded. Proceeding with Deploy". I go ahead and finish the Deploy and then my EJB works. It seems I am not including a module when I deploy it ?

Use Some Models in Web Dynpro Application

Hi,
1. When creating a model we need to refer it to r/3 environment. what should we do if we transfer the application to another environment?
2. I would like to have an application with 4 views that each one activates A DIFFERENT bapi/rfc function.
Is It ok to create some models in same application ?
Thanks in advance,
Ronit

I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,

Generate web service model in web dynpro

Hi,
I have a web service which I generated a model in web dynpro and working fine.
But the problem is that when I update my web service(change in method prototype, number of parameters, data type changes) I need to regenerate the model again and need to map to context elements.
So, is there any way so that I can update my model instead of regenerating entire model to reflect to new changes in web service.
Thanks for your time and effort.
Regards,
Shiva.

Hi Shiva,
Please look at this weblog for reimporting web service model.
/people/bertram.ganz/blog/2005/10/10/how-to-reimport-web-service-models-in-web-dynpro-for-java
There is no direct method available for that. But u can do by following this method.

Error while importing EJB model in Web dynpro: Unable to fetch the EJBs.

Hi,
We are getting the below error while importing ejb model to Web dynpro.
Error :
Unable to fetch the EJBs. Check if the selected Enterprise Application contain the EJBs.
I have created the public part-> It has a reference to EJB client and the enterprise application also has reference to the EJB project.The EJB is also added in dependency list.
But still we are getting this error. Could anyone please explain what can i do to solve this issue.
Best Regards,
Karthika

Hi Vishweshwara,
Thanks for your reply.
Please find the steps i followed while importing EJB model in webdynpro.
1. The Entity forwarding permission has been enabled.
2. public part reference has been created and through the reference entity option the ejbDC->Client public part is selected.
I followed all the steps mentioned in the document. But still i am getting that error. In EJB DC we have list of JPA entities and stateless session beans are exposed as a webservice(top-down manner).The enterprise application has a reference to the EJB DC.
I could be able to invoke the ejb service beans from ejb explorer and Webservice navigator.
I am able to insert,delete and modify the records from there.
Please let me know what could i do to resolve this error?
Best Regards,
Karthika

Using .properties file in web dynpro

Thanks & Regards,

Hi,
Go to the navigator view...select src\Components\<ComponentName> and create create a .properties file.
You can read the configuration file in your webdynpro app as follows
IWDConfiguration configuration =
      WDConfiguration.getConfigurationByName(
        wdComponentAPI.getDeployableObjectPart(),
        "<<>>");

Using macromedia flex in web dynpro

how can i use flash object in web dynpro for displaying charts instead of using the webdynpro default charts .
i want to use from NWSD not through the portal ..

Hi Valery,
I didn't say that it is the only solution. But this could be one of the solutions. Now, it depends on the requirement whether need to use it or not.
Hi Yashpal,
No need to use WDURLGenerator service. You can directly give flash object name which you have imported in mimes->components-><package>.

Hi Gary,
> Now do I put this back in original directory
Rrrighty.
> do I need to add back .bak or leave as .par?
Leave as PAR. If the server starts, all .par files within this directory get deployed and in the case of success, .bak gets added. So .par.bak files are not deployed again on the next startup.
> do I need to delete original
> then add my updated version?
I think you don't need to delete the original, but just do it. If your changed .par file get deployed successfully, it will overwrite the old .par.bak anyhow.
But make a security copy of the orginal file for the case that you have changed the original PAR in some strange way
Hope it helps
