Creation of JCO Destinations for web dynpro

Hi all,
I read quite a lot of post concerning the subject but unfortunately I did not found a solution to my problem.
My goal is to create JCO Destinations to make my web dynpro to connect to an R3 system.
In order to realise this I followed these steps :
- Launch visual admin and set http settings, rfc settings, and cim client settings. I click on CIM client test and the result is a success so I assume this part is correct.
- In R3, I execute transaction smgw, go to remote gateway to get the gateway settings. I execute RZ70 and filled the parameters just checked. Then I activate and launch the data collect. I have no error message and everythings seemed to work fine.
- In the sld (<host>:<port>/sld) I configured my server settings, the I go to data bridge, set update local sld to true and fill RFC gateway info with the same values as in my R3 system. Then I restarted the sld.
- Finally I went to Web Dynpro content administrator to create my destinations and there I failed. After entering all settings (the message server appears in my technical landscape in SLD), when I click on finish I've got the following exception :
[code]

I tried to create a generic destination (no for the web dynpro tutorial) and failed again.
I do not undestand what I did wrong.
Does someone have an idea ?
Thanks for reading this !

This thread helped me too because before reading it I didn't thought that I had to create a logon group "PUBLIC".
Anyway I succed in creating 'WD_FLIGHTLIST_MODELDATA_DEST' and the test is ok. The problem was that in sld / technical system / web as abap, my Central Application Server host was wrong. It is not possible to change it so I just add a secondary server with the right host and select this one when creating the destination.
The only pb remaining is now 'WD_FLIGHTLIST_RFC_METADATA_DEST'. I think the pb is my message server such this is the only difference between the two destinations
Thanks for your help

Problem in connecting JCO destination in web dynpro

HI all,
I was installed sneak preview of Net weaver 6.4,
I want to do some web dynpro (java) programs which connect to back end systems.(R/3 system).
The R/3 system which I want to connect is at remote place, i have connectivity to that R/3 system using VPN connectivity. With this I am not having any problem. Since I am able to connect using User name and password, and able to do some transactions like RZ70, etc.
I developed an application which calls COMPANY_CODE_GET_LIST (BAPI function).
for the above requirement what I did was
(1)I created SLD setting.
(a)Web as Java (I am not having any problem to
Create this.
(b) Web as ABAP.
When i am trying to create
This, there are some steps like i need to go to SAP log in and I need to run the transaction RZ70. For this i need to create an enter in visual administrator>JCO RFC Provider>runtime-->Bundles i need to create an entry for RFC destination as well as Repository.
under RFC destination there are some fields which i need to enter those are (a)Program ID as mySLD (b) Gateway Host as 10.10.10.125 (c)Gateway service as sapgw00 (d)Number of processes as 1
Under Repository (a) Application server host 10.10.10.125 (b)system number as 00 (c)Client number as 100 (d)Language as en (e)user as ABCD (f)password as 1234
I haven't choused the check boxes Local bundle and Unicode and pressed the set button. So like this i created the RFC destinations. under the properties tab there is a property called RFC_DEFAULT_DESTINATION by default it was false so i made it as true. .
I also went to SLD Data Supplier,under Runtime tab , HTTP Settings , I mentioned
(a)Host: pava-vis75
(b) Port: 50000
(c) user: administrator
(d) password: abcd1234
RFC Settings, I mentioned as
(a)Gateway Host: 10.10.10.125 (which is SAP R/3 system)
(b)Gateway Service/Host: sapgw00
CIM Client Generation settings, as
(a)Host: pava-vis75
(b)Port (http/https):50000
(c) user: administrator
(d) Password : abcd1234
I tested the CIMClient Test by click the the button. I got the successful message.
Then I came back to HTTP settings and clicked the button with tilted arrow mark [This triggers data transfer to system landscape directory], for this also I got a successfully message.[data transferred successfully]
Next I been to SAPLOGON and went to RFC Destinations by using sm59 transaction. There under TCP/IP connections i been to SLD_NUC , opened this by double clicking that and under Technical settings for Program ID I had given the ID which I created at visual administrator [JCO RFC Provider] which is mySLD , under gateway options for Gateway Host as 10.10.10.125and Gateway service as sapgw00 then i tested the connection, it was also successfully.
Then I opened the SLDAPICUST and i created a new entry for maintaining the SLD Access Data by giving some couple of entries as
(a)Alias: vissldtest
(b)Host Name: pava-vis75
(c)Port: 50000
(d) user: administrator
(e) password: abcd1234
Then saved it.
Next I created sapmsUV0 3600/tcp entry at
WINDOWS\system32\drivers\etc\services file, and also there are some required entries which are already existing those are sapgw00 3300/tcp to sapgw99 3399/tcp , another entry starts from sapdp00s 4700/tcp to sapdp99s 4799/tcp , next entry starts from sapgw00s 4800/tcp to sapgw99s 4899/tcp and sapmsJ2E 3601/tcp .
I restarted the system, as well as server.
Now my problem is when I was trying to create JCO destination at web dynpro content administrator. For that I navigated as create JCO Destination Deployed Contentlocal-local/CompanyCodeGetList-Applications CompanyCodeGetList
I Choosed the JCO Connections tab- there are 2 entries those are
(1) COMPANY_CODE_MODEL
(2) COMPANY_CODE_RFC_METADATA
So I started creating connection for COMPANY_CODE_RFC_METADATA.
First one is
General data Name : COMPANY_CODE_RFC_METADATA
Client : 100
I didnt changed any default JCo pool configuration.
J2EE Cluster
There is a check box called Use Local J2EE engine J2E on pava-vis75 so I choosed that.
Connection Type
Dictionary Meta Data and application Data
I choosed the first one.
Then
Msg. Server Connection
Security
After these, I tried to test the connection by clicking the Test Connection.
It is saying the error as
First time
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service 'sapmsUVO' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
second time

Can any body please help me to solve this problem.
From past 1 week on wards I have been trying to resolve this. But in vain.

It does not necessarily mean that you have to change that parameter. I read that blog as I had a similar problem, and after reading it and understanding the reasons and possible causes for the error, I found that my particular problem was that I was using "PUBLIC" as the logon group in my JCO destinations, but such a group does NOT exist at my backend. I went to transaction SMLG, had a look at Logon Groups, noted that there were none other than SPACE, figured out that I had to include that information in SLD (Web AS ABAP tech. system --> Message Server --> Logon Groups), put it there. Voilá. It works.
Edit: That SPACE logon group is the one I had to use at JCO destinations. Sorry I forgot to mention that one...
Regards,
Eduardo.

JCO Connection for web-dynpro tutorials (EP 6.0 SP9 downlaod from SDN)

Hello,
I have a question regarding JCO connections for web-dynpro example/tutorials. I have installed WAS 6.40 sneak preview from EP 6.0 SP9 download from SDN. Installation instruction says: Choose "No SLD available"
but the web-dynpro example/tutorial asks to create JCO connections by going to web-dynpro -> content admin..etc on http:<host>:50000..Here, all the tabs relating to creating JCO connections appear to be "protected" on my screen. so I can't do anything further. By going to http:<host>:50000/sld, I also tried to add SLD server..but that is not helping. There is some "import" button, but which CIM file (in which folder etc) am i supposed to import for a simple test system? What are the steps for a bare minimum setup so that I can use the WAS 6.20 system at work-place as my backend & try out the web-dynpro examples? Do I really need SLD setup? Where is documentation about all this after one installs the WAS 6.40 JAva? I was expecting it somewhere at least in the eclipse IDE help-documentation..None of the web-dynpro tutorials explain this !
thanks

Thanks everybody.
NagaKishore, after doing all the steps, when I goto
localhost:50000-> web dynpro -> content administartor, and try to "maintain JCO Destinations" I am getting this error: (full stack trace not included)
An error has occurred:

Logical Destinations in Web Dynpro Java

Hi!
Is it possible to access logical HTTP destinations maintained in SAP NetWeaver Administrator via Configuration Management -> Security ->Destinations in Web Dynpro Java source-code.
I would like to use such a destination to configure an URL target for a IWDFrame UI element.
Thank you very much in advance!
Regards,
Thomas

I found out that there is a [Destination Service API|http://help.sap.com/saphelp_nwce711/helpdata/en/8b/8e7dac1e661d44bf2a676fd3948cc6/content.htm] for this purpose. Unfortunatly I am still not able to provide the required components security.class and tc/sec/destinations/interface to the web dynpro component. Maintaining them via Project Properties -> Web Dynpro is not allowed any more, and I couldn't find them in the DC perspective to add them as DC dependency.
Has anybody got an idea where these two libraries have gone?

Thomas

How to configure SSO for web dynpro ABAP (not web dynpro Java)

Hi Experts,
    I am testing SSO in IDES for web dynpro ABAP (Not for web dynpro Java / not for portal). When I am entering url of web dynpro application in web browser like internet explorer, then it should ask for user id and password first time, after login whenever user would access that url, it must not ask for user ID and password (url would be access web browser in mobile). For this I select to configure single sign-on for web dynpro ABAP. I have done below works:
1). I have created a web dynpro application having url: http://susws076.sap.swk:<port>/sap/bc/webdynpro/sap/zadb_hello_world2
2). I run TCode SICF and access service node to "Zadb_hello_world2". Double click on it, hit change. pressed "logon data" tab, select "Alternative logon
     procedure"
   Then deleted all logon procedure other than "SSO Authentication" and saved.
3). Go to "STRUST" and create certificate, choosed "Environment==> Logon Ticket" fill the required parameters and execute. It is OK (no red traffic
     signal).
4). Execute TCode "RZ10" to change profile parameter, insert new parameter (indicated by red arrow)
After all this settings I opened a browser enter above URL and hit enter but there is an error
There is no login page. It directly showed this error page. No cookies is saving.
Can anyone tell me what all the settings/configuration other than this I have to do. And is there any wrong setting done by me?
How to set the for single sign-on?
Thanks in Advance

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in
Kind Regards,
Owen

How to call custom themes for Web Dynpro ABAP Application?

Hi,
I need to change the appearance of Web Dynpro ABAP application. So far I followed below steps,
1.     Created theme folder u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019 ).
2.     used program BSP_UPDATE_MIMEREPOS to dowmloaod content of u2018sap_tradeshowu2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> sap_tradeshowu2019) to desktop.
3.     Modified the themes using Eclipse Theme Editor.
4.     used program BSP_UPDATE_MIMEREPOS to upload modified themes to MIME repository u2018testngou2019 (SE80->MIME Repositoty -> SAP->PUBLIC->BC->UR->nw5->themes -> u2018testngou2019) .
My current URL is like http://server.name:XXXX/sap/bc/webdynpro/sap/hrrcf_a_startpage_int_cand?sap-client=XXX.
Now I want to know how custom themes called for Web Dynpro ABAP Application.
Is my approach correct?
...Naddy

Hi Naddy,
What you used is one way and even I failed when tried that method,
Instead go to SE38 - WD_THEMES - and you need to upload the zip file and you need to follow a folder structure.
it is case sensitive, atleast the zip file.
Make a zip file by name "Project.zip" -
Create a Folder Project and have the below folder structure,
1 data - all the properties files and also the designinfo file, below is the code
2 themes - (to get all the files download the theme from portal and you will have all the folders)
   2.1 ur
     2.1.1 name of the theme
       2.1.1.1 common
       2.1.1.2 csf
       2.1.1.3 r
       2.1.1.4 ur - all the css files (would be good if you can get the files from the server.)
       2.1.1.5   WSRP
3 war - empty folder
*.designinfo
isVisible=true
version=7.0.14.1.0
isDefault=false
isSapDesign=false
designName=**** name of the theme
Once done create a zip file and click on Start Import and give the path and will ask for transport request, it will take a while to upload once done as mentioned in the use the parameter sap-ep-themeroot="path"
This will resolve the issue.

SAP tool to estimate time for web dynpro development project

Hi,
Is there any standard SAP tool available to estimate time for web Dynpro development project?
Thanks and Regards,
Deepti

Hi Deepti
An implementation of Webdynpro based UI could be estimated by a 'standard' technique like any other U:
1. Try to count the number of views/screens/popups in your application. The estimation time will be proportional to the quantity.
2. Try to count the number of external interfaces would be used in the application. For example, quantity of necessary BAPI invocations (RFC), quantity of Web-service invocations or EJB calls. Also quantity of native JDBC queries if any.
Test = Nviews x Hview + Nint x Hint, where Hview & Hint time in hours for average implementing of one UI view and time for adding of average service invocation.

Create Transaction for web-dynpro ABAP

hi
Can you help me in creating a transaction for web-dynpro ABAP.
thank you.

If you want a SAPGUI transaction code that will launch your Web Dynpro ABAP application then I suggest creating a parameter transaction code that wraps around the SAP standard transaction code WDYID. You can use the parameter STARTMODE to decide if you launch your browser within the SAPGUI window or if it opens a new browser window. You will get SAPGUI based Single Sign On with this transaction code as well. Here is an example of a TCode I setup:

And here is what it looks like when running in place within the SAPGUI:

Coding standards for Web dynpro ABAP

Hello all,
Can anybody please help me by providing the code review checklist for Web dynpro ABAP?
Thanks and Regards,
Rohini Shankar

Hello friend,
WebDynpro     *
1     Do not implement Data intensive operations in UI layer
2     Avoid database selects in the WebDynpro code.Use the corresponding BAPIs ,Methods
3     Are ABAP OO Classes like Assistance class are being used for application coding ?
4     Are Windows/Views only used for the sole purpose of hosting views and context?
5     Are a reasonable number of views put in a single WD Component instead of creating multiple WD Components ?
6     Unneccessary usage of dynamic programming and dynamic component avoided
7     Are singleton nodes used in case of nesting in the context ?
8     Is deep nesting of containers, Groups and Tabstrips avoided ?
9     Is the UI element TreeByKey or TreeByTableNestingColumn used instead of the Tree UI element ?
10     Is the checkbox "Accessibility Checks Active" ticked in the WD Component properties
11     Are the WD Component Instances deleted when no longer needed (IF_WD_COMPONENT_USAGE=>DELETE_COMPONENT)
12     Are the OTR texts defined for all the labels, texts(where ever appropriate) in properties of all the UI elements
13     Has the Generation limit been checked for all the components developed
14     Sufficients commets are written at the beginning of every major block to explain the processing logic.
*Error Handling     *
1     Is SY-SUBRC checked after CALL function modules
2     Use Assertions if you face unexpected errors which usually never ever occur!
Extended Check and Clean Up
1     Have following been removed :
     ·      Unused variables
     ·      Unused text elements
     ·      Unused tables from TABLES statement
     ·      Commented out parts of the code
     ·      Code segments which do nothing
2     Is extended program check completed and all errors/warnings removed
These are the things which i used for my project.
Thanks,
Sri Hari

Want docs for Web Dynpro ABAP

Hi All ,
Can anyone please send me the Docs or link for Web Dynpro ABAP .
Thanks in advance
Rahul

Hi,
Web Dynpro ABAP
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/db22242d-0701-0010-28a2-aeaa1fefd706
Also, I have the official Web Dynpro for ABAP documentation. Please let me know if I should send it to you.
Hope that the following also helps you.
Web Dynpro for ABAP (WD4A, WDA) is the SAP standard UI technology for developing Web
applications in the ABAP environment. It consists of a runtime environment and a graphical
development environment with special Web Dynpro tools that are integrated in the ABAP
Workbench (SE80).
Web Dynpro offers the following advantages for application developers:
? The use of declarative and graphical tools significantly reduces the implementation
effort
? Web Dynpro supports a structured design process
? Strict separation between layout and business data
? Reuse and better maintainability by using components
? The layout and navigation is easily changed using the Web Dynpro tools
? Stateful applications are supported that is, if the page is changed and the required
data remains intact so that you can access it at any time throughout the entire
application context.
Note that stateless applications are not possible.
? Automatic data transport using data binding
? Automatic input check
? Automatic operation of the Web Dynpro application using the keyboard
? User interface accessibility is supported
? Full integration in the reliable ABAP development environment
Web Dynpro Architecture
Definition
Web Dynpro is the SAP NetWeaver programming model for user interfaces (UIs).
The Web Dynpro model is based on the Model View Controller paradigm, and has the
following features that build on the classic dynpro model:
? Clear separation of business logic and display logic
? Uniform metamodel for all types of user interfaces
? Execution on a number of client platforms.
? Extensive platform independence of interfaces
Structure
Metamodel Concept
Web Dynpro provides support for developing Web representation of a business application.
You use specific tools to describe the properties of a Web Dynpro application in the form of
Web Dynpro metadata. The necessary source code is then generated automatically and
executed at runtime. In addition to the events offered by the framework, you can also define
your own events for a Web Dynpro application. However, the event handling must always be
programmed in separate source code areas which are executed automatically when the event
is triggered at runtime.
In Web Dynpro, each user interface is always made up of the same basic elements. These
elements of the metamodel can be statically declared using Web Dynpro tools.
It is also possible to implement elements of the metamodel at runtime and to change them or
reintegrate them at runtime. Using these implementations, you can make any changes or
enhancements to a user interface that has been created by declarative methods by
generating new interface structures at runtime.
This means that you can combine declarative processes and the implementation of source
code.
Graphical Development Tools
To support this declarative concept, both the SAP NetWeaver Developer Studio and the
ABAP Workbench contain a range of Web Dynpro tools. You can therefore generate a large
proportion of a Web Dynpro application using the tools provided, without having to create your
own source code. This applies to the following parts of the application:
? Data flow between the front end and back end
? Layout of the user interface
? Properties of user interface elements
The Web Dynpro tools enable you to create source text areas manually within generated
source texts. These areas are not changed if the source code is regenerated.
Separation of Business and Application Logic
Using Web Dynpro enables a clear separation of business logic and display logic. A Web
Dynpro application runs on the front end and has local or remote access to the back end
system via a service. This means that the display logic is contained in the Web Dynpro
application, while the business logic and the persistence of the business objects run in the
back end system. The following options are currently available for connecting Web Dynpro
applications and the back-end system:
? An interface generated using adaptive RFC, through which BAPIs of an SAP system
can be called
? An interface for calling Web services
? A self-generated interface
The source code required for connecting the Web Dynpro application can be generated
from a UML definition of the Web Dynpro interface. A UML definition can be imported
into the Web Dynpro tools as an XML file.
Conversion of the Model-View-Controller
Conversion of the Model-View-Controller Programming Model
Every Web Dynpro application is structured according to the Model View Controller
programming model:
? The model forms the interface to the back end system and thus enables the
Web Dynpro application access to data.
? The view is responsible for the representation of the data in the browser.
? The controller lies between the view and the model. The controller formats
the model data to be displayed in the view, processes the user entries made by the
user, and returns them to the model.
