Import and Export of Webdyn pro development components

Hi
I am having a problem in importing a development component.
When a component has to be transfered from one NWDS to another NWDS i generally export the development component as a zip file. How do i import the Zip file into other NWDS. I tried the import option but the import is not proper.
Any other way of exporting and importing development components ?
Regards
NagaKishore

Hi Karin,
I faced a similar problem some time back. I unzipped the project and then imported it. But what i found is that in the webdynpro explorer i could not find the nodes for Public parts and so which are specific to DC projects.

Eventing between 2 Local Development components possible ?

Hello,
I have 2 Local DCs named 'Main' and 'Search'. As the name suggests, Main embeds Search in the "Used Web Dynpro components" and passes (via context mapping) a search parameter to Search. Search will appear as a popup window and display the table results if a match or several matches are found. User then have the option of selecting the one of the result from the table or cancel the search.
Everything works fine till I am trying to fire an event from Search to call the handler in Main. It seems that Search is not able to 'see' the handler that i have created in Main and is not able to close the popup search window.
The tutorial "Dialog Boxes in Web Dynpro Applications" demonstrates how to do eventing within the same component but I will like to know how can I do the above between 2 different Local Development components. Does anyone have a solution or idea to this ? Thank you very much.

Hi,
I think with that search parameter you can also pass on an extra parameter say <b>win</b> of type <b>IWDWindow</b> containing the reference of the window created in the main view.
In the popup window on action close of the window, instead of calling the handler you can directly give
win.close();
win.destroy();

How to use common resource bundle across all the development components ?

Hi,
I am working on SAP NetWeaver Developer Studio - JAVA
How to use common resource bundle across all the development components ?
Description :
I have a requirement of creating a resource bundle (resource.properties) and use that common resource bundle in all the development components.
Can we create a development component (war and ear both) and create only resource.properties in this development component( DC ) and create the dependency of the same DC in all the other DCs ?
Thanks,
Neha

Hello Neha
This question is more NWDS related.
You may have a better chance of someone answering the thread under
SAP Netweaver -> SAP NetWeaver Development Infrastructure (NWDI, formerly known as JDI) forum

Backward Navigation in development components

Hi folks
According to my scenario, i have 3 DC's named A, B, C.
A is master DC and is using B as used DC's in metadata . where B is using DC C. So there is linear dependency between them.
Now my requirement is to navigate from A to C through B.and vice versa.
Default inbound interface plugs of B and C are used to navigate forward by A and B respectively.
Now direct backward navigation is possible up to second level through Out Plug of Interface Controllers i.e from B to A and C to B respectively.
My Requirement is backward navigation from C to A without creating cyclic dependency and using dc C in dc A.
I have more than 3 development components which have to navigate back to dc A.
Thanks in anticipation,
Mandeep Virk

Hi Naga
This is a good piece of information but regarding navigation nothing is provided.
Here author is using ViewContainerUiElement in consumer for other components which i can not use because i have buttons in views on action of which i am preforming some methods and passing context values to other components.
If i use ViewContainerUiElement still i have to navigate using plugout of interface controllers. i can not directly navigate directly coz it will not pass the context to next component.
Any idea

Any factors that Development Components cannot be imported?

Dear all experts,
I am new to Webdynpro development. I have tried to open a webdynpro program developed by other developer before.
1. Copy the source code under my documents and settings, e.g. d:\Documents and Settings\xxx\.dtc\LocalDevelopment\DCs\com.xxx.xxx
2. Select File > Import and then select Development Components and logon my account to server. Supposing the component would be appeared under Local as usual. However, this time, I cannot see the component imported.
May I know do you have any idea for about? Thank you very much!
Best regards,
Anne

Hi,
You can export the DC present in the developer system and then import that .sca file into your System.
Then refresh the Developement Component.
Now right click the DCs available and select Create Project if it is available.
In the next step right click on the DC and select sync Used DCs.
Then Build and Deploy the DCs.
If you have any problem (errors) while Syncing or Building check the error log for Missing DCs.
For any guidance on importing and exporting the Development Component follow this link.
/people/srinivasan.subbiah/blog/2008/03/21/team-oriented-development-without-remote-nwdi-in-ce-71
Note: The Developement Configuration package should be same in both the systems.

Active and inactive development Components

Hi,
What are active and inactive development Components ?
Thanks,
sowmya

Hi,
Basically in the Development Configuration you will be able to see 2 types of development component.
1)Active
2)Inactive
Whenever user needs to change any coding or development then he needs to do this in the inactive DC.
After check in the activity it will sync with the Active DC.So that means the Active DC is contained data after the check in activity.Both are sync.We are not able to do any changes in active DC.
This is the restriction by sap
Thanks

Import the existig Development Components using NWDS

Hello Portal Developers,
I have a query and need your help to resolve it.
I would like to import the existing Developed Components (DCs) from portal.
How can it be done? Can i use the NWDS to import the existing DCs.
Your earlier help will be very much Appriciated.
Thanks in Advance
Regards
Srinivas

Hi srinivas reddy ,
You must have the NWDI for importing the existing DC's into your NWDS. If u don't have NWDI configured, you can not get that back to NWDS. Instead you can open the DC which you deployed before and modify them and redeply.
reward points if useful
Thanks

Delete development components from shared repository

We have some test models in the shared repository that need to be cleaned up. In visual composer, how can you delete development components from the shared repository?

Hi,
it is possible to delete a whole DC from DTR by commands:

API for getting the build date of development components

Hello ,
we are changing the format of the <about> screen of our application. We show the version of the main development components that are the part of our application.
For the version date of the development components, we were earlier showing the deployment date. However we now plan to change it to their build date. We need to know if there is any API to find the build date of the development components.
Thanks alot in advance for helping!

Hi do you want all the dates from the back date to sysdate or only the particular back date
SQL> select sysdate from dual;
SYSDATE
22-JUN-09
SQL> select sysdate-10 from dual;
SYSDATE-1
12-JUN-09or if you want all the back dates starting from one particular then
SQL> select sysdate-10+level from dual
2 connect by level<=10;

Web Dynpro Development Components missing for MSS

Hey Guys...
The following BPs are installed on our landscape:
○       Business Package for Manager Self-Service (SAP ERP) 1.3
○       Business Package for Common Parts (SAP ERP) 1.3
○       Business Package for Project Self-Service (SAP ERP) 1.0
○       Business Package for HR Administrator (SAP ERP) 1.1
The ECC is EHP 3, SP 14 and EP is 7.0 SP 14
I've been trying to set up iViews for MSS but I see that all Web Dynpro Applications specified in the technical information of iViews are missing. I searched for Web Dynpro Development Components in the EP and all MSS related WDC are just missing.
According to SAP Help Documentation (http://help.sap.com/erp2005_ehp_03/helpdata/en/76/77594d165144a1a9bff9aae1e26b26/content.htm) these are required:
Web Dynpro Development Components:
○       PCUI_GP
○       MSS
○       SAP_PSS
Where can I get them??? Is it possible our basis didn't install the right Business Package?

Seems you have got right business packages, though have a look at note [1303362|https://websmp230.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/sapnotes/index2.htm?numm=1303362] to confirm dependency.
"but I see that all Web Dynpro Applications specified in the technical information of iViews are missing."
Well this could be because of errorsome business package deployment, you can still check list of deployed components from SDM and if there is any error log for deployement, you should try to deploy them again(update existing components).
Hope this helps. If not then probably you should go Content Admin - WebDynpro and see list of application listed under MSS.. if those referred applications are available then try to execute them.
And last one.. if you "think" they wont run.. or you have actually tried to run MSS and none of applications are working. you should be able to run standard package without any major configuration chanegs.. so give it a go.. and see if you encounter any error.
Cheers

Management of Beanu00B4s Relationships in Development Components

Hi,
I´m developing a project where I need to use DC for reutilization. I have already created two DC, one DC that contain an entity bean call Improvement and other DC that contain an entity bean call LongText that has the Improvement primary key like a foreign key. So, I need to establish an one to many relationships between the entity beans that are in different development components, but I created the LongText public parts and I did add them to the Improvement Used DCs, and I did create the relationship between the two of them in the ejb-jar.xml of the Improvement DC because I need it to be unidirectional, but doesn´t appear for add the relationship in the persistent.xml.
I´m using the SAP Developer Studio 2.0 SP13.
If someone know what can be the error, I will we grateful.

Hi Experts,
Could you please reply any one.
Thanks in advance.

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 ?

Thanks Jan! It solved!
I have already created another workspace after all the tests just to be sure that the problem wasn´t on NWDS.
It solved to me when I removed the reservation on SLD and recreated.
Thank you so much!

Custom types for Developing Components

I am creating the custom component for the LiveCycle and I ran into problems, because there are no sufficient documentation how to define and use a custom data types. I have read your article from the DevNet and you refer to the documentation many times. I was very disappointed, because the documentation isn’t handle the custom data types like you have described it. My problem is how to define the custom data type in the component xml. The structure of the custom data type is
ScanProperties
private String virusScanPath
private Priority priority (Enum type)
private Action action (Enum type)
private boolean all
private boolean allole
private boolean archive
private boolean mime
private boolean mheur
private boolean pheur
I will use this custom data type as an input for my service. So my main problem is how I can define the correct set up of the object from the process using the correct editors?
Posted on behalf of Veijo (last name withheld)

Usually custom data types (such as the priority and action types you stated) are added to the component.xml file using the data-types element.
For example, I have created several custom types (Part, OrderResult, PartsOrdered, Pricing and PartColor) that I want to expose in LiveCycle. I want the user to be able to select these types from the drop down when they create process variables inside Workbench. This is done by adding the class’ for each type to the data-types tag:
      <data-types>
            <data-type id="com.adobe.samples.customTypes.Part" title="Part" standard="true">
            </data-type>
            <data-type id="com.adobe.samples.customTypes.OrderResult" title="Part Order Result" standard="true">
            </data-type>
            <data-type id="com.adobe.samples.customTypes.PartsOrdered" title="Parts Ordered" standard="true">
            </data-type>
            <data-type id="com.adobe.samples.customTypes.Pricing" title="Pricing" standard="true">
            </data-type>
            <data-type id="com.adobe.samples.customTypes.PartColor" title="PartColor" standard="true">
            </data-type>
      </data-types>
The data-type attributes are:
id - Required. The identifier used to look up a data type globally (across components). Its maximum length is 255.
title - Short descriptive caption expected to be displayed in any related UI. The title is not defined if id is used in place of title.
java-class - The underlying Java type for this data type that will be used internally and on the signature of an operation when used as input and output. If java-class is not defined, it is assumed that id is the Java class.
standard - A Boolean flag specifying whether this data type is a standard data type. If true, it is expected that applications such as Workbench ES will show this data type by default and not require a search across the data type registry. The default is false.
I also see that you want to use an enumerated type. I’ll assume that you would like to see a drop down in the properties sheet that allows the user to select from a list of possible values. To do that you want to use a property-editor with the type Enum in your input parameter section:
<property-editor editor-id="com.adobe.idp.dsc.propertyeditor.system.Enum" />
I’ve included a sample component.xml (the same one from my DevNet article) that should supply you with the context of the elements.
