Is WebDynpro ABAP a viable option?

Hi all
Some generic questions, is WebDynpro ABAP a viable option? Can I suggest it to the customers? Is it a good practice to have UI and Business logic on the same server? Y are two strains of webdynpro one for ABAP and one for Java necessary?
I have also heard ESS MSS runs on both ABAP and Java WebDynpro. Y is SAP complicating the skillset required to deal with Business Packages? Please give me links or direct answers as suitable. Thank you all.

Hi Volker
All that I have written is based on help.sap.com. And here is the link (Go to WDJ in Travel manangement and look at constraints).
<a href="http://help.sap.com/erp2005_ehp_02/helpdata/en/46/51f0e994b85e40e10000000a11466f/frameset.htm">ECC 7.0 WDA</a>
And yes you are right, ECC 6.00 is enhanced using EHPs -> enhancement package. I am talking abt EHP 2.
I am using CAF on NW 7.0 and hence the concern. And when I say composite my UI is essentially calling faceless services. That alone gives me the power to orchestrate processes quickly. The only reason I put these questions is because the same are coming out of my customers too!! And I need to give a concrete answer on the UI paradigm as well. Though I have made up my mind the future releases of ESS MSS is troubling to hear. Thank you for the patience shown in answering my questions.

OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

Hi Experts
We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
Rrgards,
Srikanth.
Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

Hi Srikanth,
as you seem to be already aware, the component is dynamically built.
so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
What is it about this that you particularly want help with?
Cheers,
Chris

Select-options in Webdynpro abap

Hi,
I want to use select options in webdynpro abap ,I checked links available in net but want a simple step by step procedure .
-Sandeep

Hi,
What do you mean by simple steps? You need to write little code to add select options in WDA. You can check this wiki for reference: Web Dynpro ABAP - Complex select-options component usages - Code Gallery - SCN Wiki
And there are lot more documents available in SCN. search here

Default Values for Select-options In Webdynpro-ABAP

Hi Freinds,
Kindly,Help me in setting the Default values for the Select-options in Webdynpro ABAP.
Here the Node and the Attributes are Created Dynamically, and then Displayed Select-options Component View.
Regards,
Xavier.P

Xavier Reddy Penta sent me this question via email and I answered it directly yesterday. Here is the solution that I provided to him, so that it is stored with the original question:
I believe your problem is that you are not setting the value into the range correctly. You are setting it directly into the field symbol of the range like such:
<FS> = L_STRING2.
But ranges are deep objects. They have four fields: Sign, Option, High, and Low. This is from the online help:
1.     sign of type c and length 1. The content of sign determines for every row whether the result of the condition formulated in the column is included or excluded in the entire resulting set for all rows. Evaluable values are "I" for include and "E" for exclude.
2.     option of type c and length 2. option contains the selection option for the condition of the row in form of logical operators. Analyzable operators are "EQ", "NE", "GE", "GT", "LE", "LT", "CP" and "NP" if column high is initial, and "BT", "NB" if column high is not initial. With the options "CP" and "NP", the data type of the columns low and high must be of the data type c, and special rules apply for entries on the selection screen.
3.     low of the data type defined after FOR. This column is designated for the comparison value or the lower interval limitation.
4.     high of the data type defined after FOR. This column is designated for the upper interval limitation.
So when you are moving the value into the field symbol you are setting it into the sign column.
Here is an example of how you can access the components of the range:
* create a range table that consists of this new data element
    lt_range_table =
      wd_this->lv_sel_handler->create_range_table(
           i_typename = l_typename ).
    IF l_fieldname = 'CARRID'.
      FIELD-SYMBOLS: <tab>         TYPE INDEX TABLE,
                         <struct>      TYPE ANY,
                         <wa>          TYPE ANY,
                         <option>      TYPE char2,
                         <sign>        TYPE char1,
                         <high>        TYPE ANY,
                         <low>         TYPE ANY,
                         <wa_values>   TYPE ANY.
      ASSIGN lt_range_table->* TO <tab>.
      APPEND INITIAL LINE TO <tab> ASSIGNING <wa>.
      ASSIGN COMPONENT 'OPTION' OF STRUCTURE <wa> TO <option>.
      ASSIGN COMPONENT 'HIGH' OF STRUCTURE <wa> TO <high>.
      ASSIGN COMPONENT 'LOW' OF STRUCTURE <wa> TO <low>.
      ASSIGN COMPONENT 'SIGN' OF STRUCTURE <wa> TO <sign>.
      <sign> = 'I'.
      <option> = 'EQ'.
      <low> = 'AA'.
    ENDIF.

Personalization option for Standard Webdynpro ABAP iView

Hello Experts,
We are stuck with an issue on personalizing a Webdynpro ABAP application. Personalization option is available for Webdynpro Java iViews, when we preview the iView from the Administrator's login and do a Control + Right click. This will provide a dialog box where we can personalize the iView. We can do personalization on the existing fields (hiding the fields, changing the text etc). But this is not happening with Webdynpro ABAP iView.
Scenario:
We have a Standard Webdynpro ABAP iView which has 3 rows of links (Row1 - 5 links, Row2 - 2 links and Row3 - 2 links). The client wants only one link in Row1, one link in Row2 and one in Row3. I tried hiding the other links through Personalization. It is not working as am able to see the changes only with the Admin ID. When I assign this iView to a different user and tried viewing the iView its showing all the links.
But the strange thing is that, if I hide the complete row (eg. Row2 both the links are hidden), then am able to see the complete row being hidden with both the Admin ID and also the end user's ID. So not sure where am I missing.
Please refer the link for the Personalization option available for Webdynpro ABAP iView.

Any help in this regard will be greatly appreciated. Thanks in advance.

Hi Volker,
   Thanks for your reply.
   I think, I have set the properties of the iView right. I have tried with all the options for the property "Launch in new window" property of the iView but it didn't work.
   "By home page framework" I mean that the link of the iView in portal has been created using the "Home page framework" i.e. from "SPRO" transaction in the backend.
   Please let me know if you need any other input from me.

Webservice in Webdynpro ABAP

Hi
Please provide tutorial and general guidelines for settings for consuming webservice in webdynpro ABAP.
Thanks & Regards,
Chaitali

Thanks Rich for quick answer.
But my problem is, I have a stand alone WAS without any RFC Function modules and dictionary structures, of backend R/3, on WAS which I wanted to map in my component.
I strongly believe that in case of stand alone WAS I need to have at least backend dictionary structures to begin with my design. I cant use wizard, as I dont have function modules on this system. I have to code for that manually..
So that is why, I was looking for Webservice option..

Webdynpro ABAP/Portal. Plugin HTTP connection issue on WaitingEventQueue.js

Hello,
We are experiencing a strange Portal Behavior with our Webdynpros. Our portal contains several iViews including some Webdynpro (ABAP) and some reporting transaction calls that use SAPgui for HTML.
When portal is called for the first time and a user logs in, two connections of type RFC can be seen for that user in SM04 in our ERP system. All iViews work as expected. For example, calling the Time Management webdynpro closes one of the RFC connections and starts a new Pluguin HTTP connection. We can go back and forth between the welcome page and this Webdynpro with no issues.
If we then select one of the reporting transaction codes, the portal launches the SAPGUI for HTML. Report retrieves and shows data, and then we close using the "Exit" button provided by the sapgui for HTML
Next we try again to launch any webdynpro (abap), but SM04 shows that the new Plugin HTTP session gets stuck and spinning mid way, and will stay there. Refreshing the Portal screen with F8, navigating back and forth, logging off and on again has no effect. The webdynpros will not launch again. Only webdynpros are affected, any of the reporting transactions can be called successfully over and over.
We have figured that deleting Temporary Internet files (we are using IE 7), and in particular by just deleting the WaitingEventQueue.js?XXXXXXXXXXX file, the system will break away from the spin loop and show the webdynpro again, but eventually it will get stuck again, and asking the users to delete their Temporary Internet Files every 5 minutes is not a workable solution
I have reviewed the contents of this javascript file at different points during the test, and the contents do not change, so deleting the file and the recreate process must be resetting somehow the queue and allowing for a new correct communication.
Is there a way to properly reset this event queue (for example from ABAP, when the webdynpros are reloaded) in order to avoid the spin loop?
Thanks for any help!
Andres

Well, we got the issue resolved, so here is what we did, in case anybody is interested:
Tested again our portal with multiple versions of Internet Explorer, in particular IE8 and IE6, the Webdynpro behavior was normal (no timeouts or locks). It even worked when we installed IE7 in a brand new machine and tried our portal.
So we started suspecting if maybe the particular IE7 that we install internally (with specific settings and policies) may be the culprit. We took a desktop that was producing the timeouts and used the following options in IE7:
Tools->Internet Options->Advanced(tab)-Reset Internet Explorer settings
and, voila! the next time we ran there, the portal did not create any timeouts.
We even asked our desktop support team to uninstall and reinstall IE7 in the same machine after we did the reset, and even after the re-install that the timeout problems did not re-appear.
One of the things that the "reset" option does is delete the Add-ons used by IE.
So as a last test, we took a machine that was presenting the problem and went to the Internet Options to disable all the add-ons (in the Programs Tab). The error disappeared.
And even after enabling back all the add-ons, the error would not return.
Conclusion:
Without being able to pinpoint the specific add-on (or combination) that causes the problem, we suspect that some of them conflicted, causing IE7 to behave abnormally. Disabling them all, restarting Internet Explorer, and enabling them again, makes the WaitingEventQueue.js work as it should

Webdynpro ABAP webservice call to external server - Cookie issue

Hi,
We are experiencing cookie issue while calling webservice to Tivoli system hosted on IBM websphere.
Steps we have done as follows:
1. Created a ABAP Proxy class from Tivoli WSDL.
2. Configured T-Code LPCONFIG to point to above proxy class and logical port.
3. Configured SM59 RFC connection to point to Tivoli server using basic authentication mechanism (User ID/Password).
4. Called webservice method from WebDynpro ABAP program.
After above steps, we are able to call the webservice method successfully but second time we are experiencing Cookie being adding to the request and eventually no response back to our program.
When we investigated this cookie issue with IBM Websphere people, they says thay have enabled SSO Config instead of basic authentication and that's why a cookie is being added to the request and fails. when they disabled SSO, we are able to call webservic method sucessfully sevaral times. but now this cannot be no longer disabled as other applications are using SSO enable option. So, we are thinking, is there something that can be done in SAP ECC itself as we see the option of using SSO in SM59 instead of User Id/Password but not sure How?
If anybody has undergone this scenario/SSO config from ECC SM59 successfully, Please reply back.
Thanks in advance
Praveen

Here is the link that explains how SSO can be configured in SAP.
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/65/6a563cef658a06e10000000a11405a/frameset.htm
Once done, under Client PSE in Tcode STRUST, you can upload the certificate obtained from the SSO enabled system and use the client PSE (Default) in the SSL Client Certificate area of SM59
I see Thomas has already responded to you and he has written a blog on how to set this up as well.

WebDynpro ABAP iView not opening in new window

WebDynPro ABAP iView not picking Portal Theme stylesheet

Hi,
We are facing issues in integrating the WebDynPro ABAP application in Portal . The WebDynPro ABAP iView is not picking the portal theme. It is picking its actual color.
We are in EP 6 SP 14.
Can anyone let me know what can be the reasons.
Best Regards
Sid

Hello,
for the web dynpro for abap application you can create a application configuration. To create the configuration
right click on the application -> create/Change Configuration -> and once you create the configuration, it will open up in browser and you can see 2 tabs structure and parameters
In parameters tab you will find an option Force Use of External StyleSheet check the box and save the configuration. Once done with this process.
Go to the iView Properties of the applications and set the application configuration name and it would take the Portal Theme.
hope this helps.
