Can CVS be used with Web Dynpro Applications?

Is it okay to use CVS as the source control system for Web Dynpro apps? Or does the DTR have to be used? How would you use CVS within NetWeaver Developer Studio?

Hi Dora,
I hope at this time there should not be any confusion, because JDI can be used for Webdynpro Applications,right from devlopment to production you can maintain the versioning.
Please go through the following links and explore more on JDI.
You need to install the JDI separately. Go to http://service.sap.com/patches -> Entry by Application Group -> SAP Net Weaver -> SAP NETWEAVER -> SAP NETWEAVER 04 -> NWDI -> JDI 6.40 -> #OS independent

Find keyword used in Web Dynpro Application?

Hi folks,
I have a simple question with regards to Web Dynpro for ABAP: Is it possible to search in my application for a keyword that I have used?
For e.g., I wish to search for the keyword "loop" to find out which parts of my program have this matching string. I have many views, windows, and code in my component controllers.
Is that possible? Please advise. Thanks in advance.

Read this thread:
how to view COMPONENTCONTROLLER interface 's implement class
With my approach you can access the generated class and search on it globally from SE24 (efectively searching across the whole component).
With Thomas approach you can only search on controller by controller basis but may be a bit less complicated to use.

Can swing be used on web / only application?

I am new to swing... Can I store the data from my database in a swing table on a web page ? Can I create a form with all swing components ?
I have heard that swing is used for application development.. I wanted to know that if you created a frame/window in swing then like how will you create say an icon on desktop which one can click to open a swing frame/window that takes you to the first menu on the application ?

Let's break down your questions.
I am new to swing... Can I store the data from my
database in a swing table on a web page ? The data is already stored in the DB. I assume you mean "show". The answer is yes, using the java plug-in. But it kinda blows. If you want to do this, why not download apache tomcat and use J2EE + JSP?
Can I create
a form with all swing components ? Same as above. You can, but it's really tricky. You need JSP

Securing Web-Dynpro application with Netegrity

Hi,
I'm developing a web-dynpro application that will be secured by Netegrity SiteMinder. SiteMinder is a reverse-proxy that authenticates the user and adds the user details as additional headers to the HTTP stream. According to the documentation I found in SDN with regards to JAAS and NetWeaver it looks like SAP has added callbacks so that I can retrieve HTTP headers in my custom login-module. I've implemented a simple login-module and deployed it, but now am stuck with the following issues:
(1) I can't seem to be able to debug the module (even when I create a simple HelloWorld.jsp and require the use of this module in the visual administrator, the debugger seems to ignore the break-points).
(2) I can't find any possibility to configure the engine so that this specific module is required for authenticating my deployed web-dynpro application.
My questions are as follows:
(1) Is it possible to use standard JAAS authentication with web-dynpro applications?
(2) How do I debug JAAS login modules?
Regards, Chris.

<b><b>Hi Adrian
During the Life cycle of your application Your connection will be Released when it is inactive for particular Time (The inactive time limit will be specified in the JCo Pool Settings that would be in milli seconds)
The RFC Connection can be Monitored using the Gateway process .
There are Some Predefined Connections in the Gatewway Process and each connection Requires approximately 200Kb of Memory.
So the memory cosumption of the Gateway process is proportional to the number of Active RFC Connection.

Web Dynpro Application connecting to incorrect R/3 instance

Hi,
We have newly configured EP.
We are facing strange problem with web dynpro applications.
They are accessing data from incorrect instance of R/3 system,i.e, if correct system instance is x , they are accessing data from y instance, on the same R/3 server.
We have checked JCO connections. SID in JCO connection is of the correct instance.
We have also checked SLD, but are not able to find out the root cause of the problem.
Are there any other configuration, settings required?Are there any settings required on R/3 side?
Can we some how track entire process from JCO to R/3?
What happens after fetching server details from SLD? Is there any other step before connecting to R/3?
Can anyone help on this?
Thanks in advance,
Apurva

Hi,
I have checked alias name (System ID) used in JCO connection.It is correct.
I have also checked System ID in SLD.
Is there any other configuration check required?
Thanks,

Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.

Replacing web dynpro application URL

Hi Experts,
I have created a web dynpro application with 2 views. view 1 has a button when I click on it it opens view2 in "external window". To do this I am getting absolute URL using cl_wd_utilities=>construct_wd_url and pass this URL into lr_window_manager->create_external_window and everything works great. Now, I integrated my web dynpro into MSS portal iview. When I click the button on view1 it tries to go to different URL (We have single sign on ) instead of actual URL which is "HTTP://<host>.<domain>.<extension>.<port>/sap/bc/webdynpro/sap/mycomponent". In portal the section "HTTP://<host>.<domain>.<extension>.<port>/" is getting replaced by "https://dev.xxxxx.com" and due to this a blank page opens up because this URL is not found.
Is there any way I can get actual URL of web dynpro application? I have done plenty of reserach but could not resolve this. Please let me know if anyone has any information.
Thanks.

I am not Sure what is going wrong here . How can it be different url ? You may have to check THE sso configuration and the system defintion in the portal. How ever you cannot see the actual url in THE portal url.
Is That Correct That your wda application with view1 is loding correctly but THE opening external window is not going good? In that case you can try to change THE generated url from cl_wd_utilities=>construct_wd_url to https protocol.

What to after Creating a Web Dynpro Application

Hello,
My question might a little stupid so please don't mind. I have created a web dynpro application where the user enters a sales order no and the output of is shown in an ALV format in web dynpro. My question is what next, I mean how do I give it to the users to use it. They should only be given the URL which is generated?
Also if i directly enter the URL it asks me for my Username Password of the SAP Logon. can this be avoided like some reports where one cant make any changes in the database just get the output this Username Password thing be skipped

How can I convert my Web Dynpro Application to Web Dynpro with GP Interface

Hi experts
I am trying to make my Web Dynrpo Application implement GP interface.
I encountered a question .
when I added GP interface controller, "Window" component also added automatically.
But I have already had a "Window" componet which contains alot of View settings.
Do I have to Use newly added GP "Window" component?
if so, do I have to recreate "Window" Componet whenever I convert to my web dynpro application implementing GP interface ?
Thanks in advance

Yes you have to use the automatically added window.

The problem is that when I run the application I receive an Unauthorized error on the connector URL.
If I open this URL on a browser I receive a pop-up for UID and PWD and when I enter the same UID and PWD I used to configure the connector I am able to login and see the WSDL.
Any ideas?

How to change the Portal Password using a link from Web dynpro application

Hello Everybody,
I have a requirement to change the user password from a web dynpro application which is available on a mobile device. Firstly User will log into the portal through a mobile device and after getting authenticated user will be redirected to the mobile application. Within this mobile application there will be a link to change the login password(Portal login). Can somebody tell me how can i change the portal login password from a link available within the mobile application. Looking forward for a suitable reply.
Thanks to all,
Regards,
Saby.

Hi Maksim,
Thanks for your reply..but i would also like to know can we directly use the Change Password Iview "persoUserPassword" from the portal. Can i directly Pass the URL of this iview from the portal to a "Change Password" link in the web dynpro application, so that when the user click this link he should be able to see this Iview on his/her mobile device and should be able to change the password from there. But i dont know whether this iview will appear properly on the mobile device or we have to have a custom web dynpro application for this purpose...Please reply with a suitable answer.
Thanks in advance.

Sarabjeet Singh.

Web dynpro application using workflow

Hi all,
I have developed a web dynpro application and attached that to the portal, so the user will login into the portal and will access the application. We have a new requirement now, when a user enters the data and hit save button on the web dynpro application, the workflow should trigger and should send the filled out (everything filled in) web dynpro application to his superior, the supervisor should be able to click on a link (which he should get through workflow) and should get the web dynpro application filled in. I am not sure how can I do this, so can you please guide me through.
Thanks,
Raj

Hi Raj,
could I suggest perhaps that you have a good search of SCN - there have been multiple posts about this sort of thing in the past.
for example : the wiki article
[Integrating WebDynpro ABAP applications with UWL for workflow in Portal|http://wiki.sdn.sap.com/wiki/display/WDABAP/IntegratingWebDynproABAPapplicationswithUWLforworkflowin+Portal]
is it perhaps that you do not use the UWL at your site? Or do you want to to send an email to the manager with a link directly to the approval application? The last case is one that I've come across many times before - it just means that you'll need to generate an approval task that is ended by a wf event and send an email to the manager with a URL parameter in the launch of the WDA application so that the app can pick up the details required to display and raise the WF event to complete the approval wf task.
There are all sorts of ways of persisting the information in the form so that the manager can see it in the approval. You can use the workflow container, you can use a db table, you could even use a shared memory area (not that I'd recommend this for this usage). But this is more a case of how to persist information in a workflow and probably a better question (search first, it's probably been answered already) for the WF forum and not the WDA forum.
Good luck in designing and building your application. Perhaps when you are done you could write a blog about your experience and further share how to do this with others.
Cheers,
Chris
