Web dympro with component

hi,
I have two web dymprO, WEB_start and WEB_flow .
Web_flow is a component of WEB_START.
In web_start we have a node "ITEM_SELEZIONATO" in the context of componetcontroller: It has one view, V_100.
The action button on this view , call a "SET_ITEM" method (in componentcontroller of web_start) that value the attribute "ITEM" of node "ITEM_SELEZIONATO' , with a value 'FLOW1'.
Than this action call component WEB_FLOW.
In modify method of web_flow I call a method "get_flow" that is in componetcontroller of web_star.
This methos get value of attribute "ITEM", but it is empty instead "FLOW1'.
I SHOW THE CODE OF MY WEB DYMPRO :
SET ITEM METHOD :
o_node = wd_context->get_child_node( 'ITEM_SELEZIONATO' ).
Setta l'Item selezionato nell'albero
W_ITEM = "FLOW1"
CALL METHOD o_node->set_attribute
    EXPORTING
      name = 'ITEM'
      value = w_item.
wd_this->fire_op_to_w_flow_plg( ). "CALL COMPONENT Web_flow.

    o_cmp_usage->create_component( ).
ENDIF.
o_interfacecontroller =   wd_this->wd_cpifc_main( ).

wHERE IS THE ERROR?
thanks .

Hi,
You want to pass the data from Web Start to Web Flo rght?
You can pass the data while firing the plugs.
See the code which I added.
I SHOW THE CODE OF MY WEB DYMPRO :
SET ITEM METHOD :
o_node = wd_context->get_child_node( 'ITEM_SELEZIONATO' ).
Setta l'Item selezionato nell'albero
W_ITEM = "FLOW1"
CALL METHOD o_node->set_attribute
EXPORTING
name = 'ITEM'
value = w_item.
wd_this->fire_op_to_w_flow_plg( g_item = w_item ). "CALL COMPONENT Web_flow."here while firing the plug pass the pararmeter.
For this to be done in the outbound plugs add the paramater say g_item of type w_item*******************************
METHOD wddomodifyview .COMPONENT WEB_FLOW
o_cmp_usage = wd_this->wd_cpuse_WEB_FLOW( ).
IF o_cmp_usage->has_active_component( ) IS INITIAL.
o_cmp_usage->create_component( ).
ENDIF.
o_interfacecontroller = wd_this->wd_cpifc_main( ).
CALL METHOD IN WEB_START.
In the event handler of the inbound plug you can get the paramter g_item with value "FLOW1"
Pass the variable g_item where ever you want.
o_interfacecontroller->get_item(

w_flusso = v_flusso
!!!!!error V_FLUSSO IS EMPTY !!!!!!!!!!!

Problem connectivity of Web Dympro with SAP Netweaver

Hi guys,
I've a problem connectivity of Web Dympro with SAP Netweaver
I installed Sap NW in a machine on the local network with IP 192.168.x.y, and I can connect to it without problems; I can use the portal and implement jobs in Visual Composer.
After installing Sap Developer Studio, I connected it successfully to the NW through the menu "Preferences->SAP j2EE engine" selecting the option "SAP J2EE is installed on remote hosts" and inserting IP address of the machine with NW (192.168.x.y) and port 3900.
Using these parameters the logon works, in fact I can see the tab "J2EE engine".
The problem is that when I try to make the deploy, Web Dynpro asks me the SDM password (that I'm sure I've inserted correctly) but it returns the following error to me:
Deployment aborted
Settings
SDM host : SVR-NW
SDM port : 50118

I want to add that I use Win XP Prof, and I set the same credentials (user "Administrator" and the correct password) I used on the machine where SAP NW is installed.

Hi Michele,
There were 2 cases I explained, and the second was the one in case your SDM was blocked. Did you try the first one?
Anyways, here is something more that you can try to get it working. In case the SDM password is valid, did you log into the portal as the Administrator? If yes, then you must have been asked to change the password. If you did change the password there, login to the remoteGUI using the Master password (abcd1234) and change the password there also to the same password you use for Administrator on the Portal. Now try again.
In case the above doesnt work, start the configtool.bat from \usr\sap\J2E\JC01\j2ee\configtool and go to secure store. Here define the J2E passwords again (the same new password you gave for the Administrator in the portal), save and restart the server. I think it would work then
Hope that helps you out!
Bye,
Sameer
P.S - the main thing is that the error you got was Authentication failure using the Administrator username. Thats why you have to make sure that the password for the SDM is the same as what you gave for the Administrator login in the portal. So after you login into the remoteGUI, CHANGE the password to what you have for the Administrator(just like the one in the portal).

How can I build a Web App with Component Combination

I learned OpenUI 5 for a while, since it's open source version release. It's really a great web front-end framework!
Now I'm working on a little web app. I design it start from a root module. And I wanna make any other view modules as a stand-alone package. (e.g. Something like Widgets can be make as a Component, and I can instance it anywhere I want). From learning of OpenUI, I think Component should be a good choice for my web app module.
But there is some trouble. When I make two Component with a parent-child relationship.Once the child Compont's router execute navTo method, the hash will be replace but not append. And the parent Component will be changed too.
The question is : how to design the route pattern can make the parent-child Components works both fine? Andreas Kunz

Hi Siqi,
currently there is no Child/parent relationship build in the framework, but you could do it.
All your child component need is the first part of the pattern from the parent component, you have to pass this one to the child component, and then create the routes dynamically:
parentPattern + "/myChildComponent"
Then the parent and the child will both react correctly on a hashchange.

How do I use Edge Web Fonts with Muse?

How do I use Edge Web Fonts with Muse - is it an update to load, a stand alone, how does it interface with Muse? I've updated to CC but have no info on this.

Hello,
Is there a reason why you want to use Edge Web Fonts with Adobe Muse?
Assuming you wish to improve typography of your web pages, you should know that Muse is fully integrated with Typekit. This allows you to access and apply over 500 web fonts from within Muse. Here's how you do it:
Select a text component within Muse, and click the Text drop-down.
Select Add Web Fonts option, to pop-open the Add Web Fonts dialog.
Browse and apply fonts per your design needs.
Muse also allows you to create paragraph styles that you can save and apply to chunks of text, a la InDesign. Watch this video for more information: http://tv.adobe.com/watch/muse-feature-tour/using-typekit-with-adobe-muse/
Also take a look at these help files to see if they help you:

Web service in Web Dynpro development Component

Hi All,
I have created a web service in SAP GUI and I have saved the WSDL file on my local PC.
Now when I create a web service model in a simple web dynpro project it works perfectly.
But when I do the same in a web dynpro development component; as soon as the web service model instance is associated with the activity in the DTR my application get hanged. I have to quit my NWDS. When I reopen NWDS my application shows following errors:

Hi Sidharth,
Which version of NWDS you are using. I was facing the same problem with SP16 sometime back.
I did find a workaround to do that. See, whenever you will create the WS Model in Web Dynpro DC, it will ask you to add some file in DTR..right!!........ do one thing press "Cancel" or "No" there. Then studio will ask one more time to add the files, in different dialog box though. Add the files from the second dialog box rather than the first one.

SAP Web Dynpro With Java

Hi Guys
A situation at work has forced me to learn web dynpro with java. I already have some experience with the ABAP web dynpro . Now the question is how much "java" do i need to learn to learn sap WebDynpro based on java. Should I first try and get a fair 'hands on' on core java and then shoot for web dynpro or should I take the other approach, that is just learn as much java as is required for web dynpro . Any suggestions?
thanks
sameer

Hi Sameer,
I believe you need not thoroughly know Core Java to begin for Web Dynpro Java but yes, you should have a fair idea about object, class and exceptions that i believe you would already have after working in ABAP. The UI elements can be just inserted into the component by drag and drop and codes correspondly would be auto generated. Only for customization of some functionalities, you will have to write code in Java using APIs.
Just go through the following tutorials recommended by SAP to start over Web Dynpro Java on NWDS.

How to create document/literal web services with WLS7

How do you create document/literal web services with WLS7 ( not workshop)
- Is it possible with servicegen and stateless EJBs as the backend component?
The default is RPC/Soap-encoded is there anyway to craft the web-services.xml
to make it document/literal
- Is it possible with the JMS-implemented web services - have not tried this yet
- Is there another mechanism?

That would be the <web-service> element in the web-services.xml file, of course.

Hi Rich,
Try adding a style="document" attribute to the starting <web-service>

The might be a way to get <servicegen> to do this for you, but I haven't

Accessing IRM Web Services with Coldfsuion

We are looking to use the IRM web services with Coldfusion. Coldfusion abstracts Web Services calls through Java calls to the point of just setting up structures and calling the functions.
My question is about the process for building the correct parameters for the IRM services. I have the JDeveloper examples working but I can't make enough sense of what is goin on through all the calls to build the proper information.
What I don't understand yet are things like where do I get the server key and at what point do I authenticate? Do I need to do separate calls for these things.
I've captured a soap transaction for the update user example in JDeveloper and see there is a serverKey but no other authentication. Is this all I need?
The web services documentation mentions authentication needs to be basic authentication. Other than that there is not more info. Is there any other source of info?

Hi
Sorry, things are a bit confused when it comes to Web Services (WS) documentation. At the moment (in 10g), it's mixed up with the older stuff in the Component API Help file. Also, apart from a few snippets and the JDeveloper examples, there is no WS sample code. We hope to address this in 11g.
The web services required HTTP basic authentication details to be set before the call is invoked. This will be the username and password of the sealing user, so that user will need to be configured to use Standard Auth, rather than NT Auth. How to set this depends on the web service stack used on the client, but with JAX-RPC there are APIs that allow the user name and password to be specified. e.g.
+// User name for authentication purposes+
contextServices._setProperty(javax.xml.rpc.Stub.USERNAME_PROPERTY,args[1]);
+// Password for authentication purposes+
contextServices._setProperty(javax.xml.rpc.Stub.PASSWORD_PROPERTY,args[2]);
This snippet is in the Help file under the header "Authentication", or directly via:
mk:@MSITStore:C:\Program%20Files\SealedMedia\Enterprise%20APIs%20SDK\Components%20SDK\Docs\smcomponents.chm::/ws_documentation_authentication.htm
As for the Server Key, each IRM Server has a unique UUID value. The easiest way to get this is to call the following web service method on the “ServerServices” web service port.
LicenseServer_ref reference = serverServices.getLicenseServerReference();
System.out.println(reference.getServerKey());
One you’ve obtained this it will never change (for the server you are using) and can be cached or stored for all future web service calls.
I think you need to have the auth properties set, and the Server Key handy, for most WS methods to work, but I don't think it matters in which order you get them.
Hope this helps,
David

Closing web browser from a Web Dynpro (ABAP) component in it

Hi,
I am opening a Web Dynpro component in IE.
I have a requirement to close the Internet Explorer window on click of a "Close" Button in Web Dynpro (ABAP) component. I am using EXIT Outbound plug of the Main Window to perform the same.
In the EXIT plug I am setting "CLOSE_WINDOW" parameter to ABAP_TRUE.
On click of the "Close" button a pop-up dialog box (with "Yes" and "No" buttons) appears asking me whether I really want to close the IE window.
If I click on "Yes" button of the dialog box, the IE window gets closed without any issues.
But when I click on "No" button, the IE window shows up a blank screen. I want the control to come back to the calling Web Dynpro component's screen.
Appreciate any help/guidance in the above issue.
Thanks,

Excessive use of CPU using WEB Dympro

We are testing of stress and the use of awaited CPU was of 40% and we are having values of 80%. This can be by the use of WEB Dympro? It can be that it has not been considered in sizing?

Hi and Welcome to the Community!
As a user-to-user community, no one here can answer your question with any level of authority whatsoever. No one here can look "behind the scenes" to see what may be going on. If you wish a formal investigation, you must start with your mobile service provider (Cosmote) as ALL contracts, finances, and services are between you and them. They have the power to escalate cases into RIM that require such.
Good luck!

Web interaction with client application

Hi all,
I have self taught myself Java over the last 4 years on and off.
I am in the mid stages of developing an MRPII application with various modules. These modules are effectively JTabbedPanes within JInternalFrames. The JInternalPanes are within a JDesktopPane which also has JTabbedPanes.
This enables me to have departmental tabs at the top of my app and module functions at the left hand side, dependant of which departmental tab is selected.
I have created a class that connects to MySql and can do various functions which I then can derive specific MRPII classes.
I have a desktop PC which I have MySql configured as a server and a laptop which is configured as a client. Both machines run WindowsXP and my router is a linksys.
With this setup both machines can check inventory, take orders, produce purchase orders, create customers & vendors etc....
My next step is to try and incorporate a web component into this.
My ideal goal is to have a database that is set up and hosted on the web and works in the same way as my home network. This would enable me to deploy this application and configure the ODBC data source to point to an IP address. Is this possible and if so how would I go about it.
The other option is to create web pages with forms that interact with my local server. If this is the better option, I am unsure whether I should learn about servlets or possibly XML, as all I have learned so far is about applications.
Your guidance would be greatly appreciated.
thanks
Jim.

I wouldn't let client applications connect to a database directly. What if you make a change to the database in order to fix a bug for example, that would mean rebuilding the clients and redistributing them and in the mean time any old client is most likely broken.
I would let the server communicatie with the database locally and expose either an XML-RPC or a SOAP connection to clients. This makes your framework extendible and abstract, all you do is implement SOAP methods on the server that your clients will invoke. As long as the response of such a call never changes you do not need to change your clients. And who knows, you may even use additional data sources (other databases for example) on your server, your clients will never have to know about it.
If you want to learn about SOAP, check out Apache axis.

Creating Room Instance from Web Dynpro Development Component

Hi Experts,
I would like to instantiate a Room Instance based on a pre-created Room Template from within a Web Dynpro Development Component. I had a look at the Collaboration Rooms API Cookbook, which provides all the code examples I need, but which asks that I import the following classes:
import com.sap.ip.collaboration.room.api.IRooms;
import com.sapportals.portal.prt.runtime.PortalRuntime;
Problem is I don't have and can't find those libraries. I am developing in a track on the DTR and all solutions that I have found to the problems thus far require me to import a local jar file. Surely I should rather import a Software Component with the required library into my project? Does anyone know what the name of this Software Component is or what the correct way is to do this?
Also, a somewhat related problem. If I want to create a Room Instance from an Application Service, how would I go about doing this. Unlike with a Web Dynpro project, I can't setup the build path or Used DCs, so how will I gain access to that library?
Thank you,
JP

Beevin, thanks for the reply.
I am aware that adding the jars manually to the build path is a possibility, but isn't this a local only solution? What I mean is, lets say I do this and check the code into the DTR - surely the code won't compile on my co-workers' machines as the paths to the jar files are different for them? Unless you mean to somehow add the jar file from the server, in which case could you please elaborate on how to do this?
This still doesn't solve the application service problem, does it? How can I access those library from the CAF DC?
Thanks
