Has anybody created Iview from "Webdynpro Java" component in CE7.1 ?

Hi All,
Has anyone created Iview from Webdynpro Java component in CE7.1.
Because the wizard that appears for creation of Iview has only "Webdynpro ABAP"
component.There is no option to create iview from "Webdynpro Java" component.
Althought in portal content--->Template folder i can see there is also
another template for "SAP Webdynpro iview" which i think is for the Java scenario.
But issue is, its not coming in the wizard.Can anyone tell me how to make it appear in the wizard ? It will be of great help to me.
Thanks and Regards
Ashis

Hi Ashis,
your deployed webdynpros are published under "web dynpro applications". just copy the webdynpro from there and paste it into the portal content section.

Calling Webdynpro Java Application from Webdynpro ABAP Application.

Hi,
We have developed one Application using Webdynpro Java and I m in need to call the Webdynpro Java application from Webdynpro ABAP.
Require Suggestions to acheive this.
Thanks In advance.
Reg,
Ajay.

Dear Ajay,
Assuming that both your applications WDA & WDJ are in the portal & you don't have to pass any parameters to the WDJ application.
Write the following code on the action where you would call the WDJ application.
DATA:
        lr_compcontroller TYPE REF TO ig_componentcontroller,
        l_component TYPE REF TO if_wd_component ,
        lr_port_manager TYPE REF TO if_wd_portal_integration ,
        wa_navigation TYPE navigation.
lr_compcontroller =   wd_this->get_componentcontroller_ctr( ).
l_component = lr_compcontroller->wd_get_api( ).
lr_port_manager = l_component->get_portal_manager( ) .
* The value inserted into the navigation-target field can be found in the Portal
* content administration tab of your portal. It is the ID or PCD Location field
wa_navigation-target = pcd. " Please provide the PCD Location of the WDJ Application here.
wa_navigation-mode   = '0'. "0 = INTERNAL(same page) and 1 = EXTERNAL(new page).
CALL METHOD lr_port_manager->navigate_absolute
    EXPORTING
      navigation_target = wa_navigation-target
      navigation_mode   = wa_navigation-mode.
You can get the PCD from the Page properties of the WDJ application page in the Portal.
Hope it helps!
Warm regards,

Calling WD Java component in WD ABAP

Hi Experts,
I've a requirement to call WD Java application in my custom WD Abap component.
In Ehp4 time management module, the time recording application is designed in WD java component while Ehp5 the same appln is designed in WD ABAP.
Now I need to call either of this application based on country grouping. For eg: If an employee belongs to US then i need to call WD ABAP component, while if an employee belongs to Canada then it should open WD Java component.
Could you pls clarify whether we can call a WD Java application using any Class / Functional module. If yes, pls let me know
Appreciate your help

Call webdynpro java Web Service from ABAP

Hello,
This is regarding calling portal web service from ABAP.
1. created web service in NWDS and deployed it to portal server
2. created abap proxy to call this web service from abap SE80 transaction
3. created logical portal for the above proxy LPCONFIG transaction
this is working perfectly. the web service is getting called from abap and funcitonality is working
but my doubt is we have no where given the login password for portal server in the abap system
then how come it works without login password
if i run this web service directly from portal in wsnavigator, then portal login is required.
If we want to incorporate authentication then how to do that ?
thankyou,
B

When you are testing the application in SE80.
Is it ot asking for the user id password.
I created a similar service and for me its asking for user id and password.
Go to SM59 and there look for a RFC destination of type HTTP Connection to External Serv. usually will be named as
SAP_PROXY_ESR.
for this connection check the logon and security tab.
may be some user id and password is given there. means hardcoded.
thanks

Http post to a url from a WebDynpro (Java) application

Hi,
I want to send http post parameters to a url from a WebDynpro (Java) component. I need to do this to send OCI catalog data back to SAP SRM.
I found this thread:
HTTP Post
which suggests to use the the Suspend plug for this purpose.
<quote>
Sending POST parameters with Web Dynpro Suspend Plugs
1) Define a an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map
</quote>
After adding the postParams parameter of type java.util.Map to the Suspend-plug the WebDynpro gives the following error during build:
Outbound plug (of type 'Suspend') 'suspend_plug' may have at most two parameters: 'url' of type 'string' and 'postParams' of type 'Map'.
I use SAP NetWeaver Developer Studio version 7.0.16.
Does someone know a solution? I would highly appreciate it.
Thanks in advance.

UWL application in Webdynpro Java

Hi
I have a requirement where I need to replicate the standard SAP UWL feature in a custom Webdynpro Java component.
The Webdynpro Java component will be a custom screen which will have all the features of the standard UWL.
When the users launch the Webdynpro application, he should be able to see all the notifications in his inbox and when he clicks on a particular task in his inbox, the task should perform the same things that it does when opened from UWL application. It should be able to trigger webservices or launch UI related to BPM processes.
Please provide your suggestions on this.
Thanks and Regards,
Sayan Ghosh

Hi Sayan,
UWL apis will provide you the methods and interfaces to replicate the similar behavior of standard SAP UWL. You can read more about [UWL API|http://help.sap.com/javadocs/NW04S/SPS09/uw/index.html].
Make sure that UWL services are started in Portal.
There is a nice tutorial that you can refer for building UWL in webdynpro. Refer - [Accessing UWL Notifications from Web Dynpro Using UWL API|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/802bfda2-8a85-2b10-9290-d67da32d0c01?quicklink=index&overridelayout=true]

Calling a java webdynpro component inside a SAP Workflow

Hi Experts ,
Is it possible to call a java webdynpro component inside a SAP Workflow from the task .
If yes please let me the procedures .
Regards
Sarmistha

Someone has posted this, Take a look if it helps you:
"1. Activate your service in transaction SICF;
2. Activate the WS_HANDLER in SICF (probably you have to do more in SICF, SAP notes will be given to you in your browser when you want to call the service);
3. Make the correct settings in WF_HANDCUST;
4. Do ofcourse SWU3 including webserver activities;
5. Define how you want to call the service via WF_EXTSRV including parameters;
6. Generate a task from your defined service in WF_EXTSRV;
7. Incorporate this task in your workflow definition;
8. Test your workflow. Here you probably get some errror messages that the service cannot be called by for instance inactive ICF services. Activate the correct paths in transaction SICF."

Call stateless session bean EJB 2.0 from Webdynpro Java UI

Hello,
Can someone please tell me asto how to call a stateless session bean EJB 2.0 from Webdynpro Java UI?
The NWDS version is 7.0.
Thanks and Regards,
Arya

Hi Aryadipta
Please check this pdfs
https://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/b00917dc-ead4-2910-3ebb-b0a63e49ef10&overridelayout=true
Steps for calling stateless session bean in Webdynpro java
Go to NWDS -> open perspective ->j2ee
select EJB Module Project ->create a project with name
Open the Project -->RC on ejb-jar.xml -> Select new --> EJB
Give name to EJB Bean (First letter should be in capital letters)
select the type of bean as Stateless session bean and give the package name to store that EJB bean.
After that Expand ejb-jar.xml and then select the <projectEJB>
Double click on this on method tab double click you will get business method where we will create the methods for business logic
Double click on projectEJB and then RC on bean tab and write required business logic in bean window as follows(based on requirement we will design a business logic).
After writing the business logic go to project -> rebuild
Till now we have created one EJB jar file
then go to File-->Enterprise Application Project -->create a project (projectEAR)
After creating a project click on next-> here we will have ear projects and then we select specific project required for our application.(here select projectEJB)
After that Calculate EAR project will be available on j2ee explorer.
Right click on <Bean> here
select New->Web Service->give a name to webservice and select Default configuration type as simple SOAP
-->click next -> Finish.
That webservice and related are created in ejb-jar.xml .
Expand the ejb-jar.xml.and double click on < webservice>
RC ProjectEJB -> Build EJB Archive RC on CalculateEAR ->Build applicationarchive.
Expand the projectEAR->RC on CalculateEAR.ear->Deploy to J2EE Engine
Double click on calculateEAR.ear ->Webservice navigator tab ->we eill servers expand the node
select the specific WebService
Here we test the webservice by click on Test and test it.
After that go to Web dynpro perspective ->create one webdynpro Project and one component
RC on model> Select import Web Service model(last)>give model name and package
and select radio button as local file system or URL
Go to WSnavigator->copy the WSDL path and paste it in model WSDL path and click on finish.
from here onwards steps are same as that adaptive RFC model
Hope it helps
Thanks

How to create and call a COM component in Java

Hi All,
can you suggest how to create and call a COM component..or if have any sample simple application can you send it to me...i will try to develop my project.
actually i am configuring a OCR Engine using SDK which is in VB .Net when i contacted their support they told that if i have any sample COM based component Project they will help me...
So please can you help in this.
Thanks in advance.

As said by my fellow posters Java Devolopment Environment (Except Microsoft implementation of JVM,this is no longer supported by MS themseleves) does not provide an built-in support to serve this cause.
If you are looking to devolop a custom based solution the below is a good place to start with where end user is talking about Java <=> JNI <=> Native <=> COM connectivity.
[http://bloggershetty.blogspot.com/2004/12/java-jni-com-activex-bridge-lots-of.html]
However,if you are looking for ready made solutions ?

Why we call adaptive RFC in webdynpro java..

Hi,
I want to know why we call adaptive RFC connection in webdynpro java whenever we import new rfc in our java web dynpro project. why name ADAPTIVE RFC is used
if we make any structure changes in the model which we imported in web dynpro project , like adding a new field, or changing the length/datatype of the existing field, then we always have to reimport the model in our webdynpro project so why adaptive name used. wats especial in the word ADAPTIVE RFC
