Connecting to R/3 System through Java Web Dynpro forms.

Hi,
I have a requirement in which I have to send data to R/3
from Java Web Dynpro screens.
I will design the Java Web Dynpro screens and write a RFC Model.
I will write a RFC in se37 which will connect to the RFC Model.
Before creating the RFC in se37, I will create ztables in se11.
I will write a ABAP Report to see that all data enters the ztables.
I need some guidance with regard to this.
Do, the RFC Model have the access of the ECC(R/3) System.
What are tasks to be told the Basis guy so, that RFC being called from through Java Web Dynpro?
Please provide me some documents with regards to this scenario.
Regards
Neha Singh

Hi Neha,
The steps you provided is clear enough to connect to a R/3 system through the WD forms.
On creating the model you need to give two inputs such as
logical system name for model instance
logical system name for RFC metadata
there will be 2 default values, also you can create your own JCOs in the <servername>:<port>/devinf of the server or u can ask your basis team also.
Before creating the JCO , the SLD (System Landscape Directory) needs to be configures, that your basis team will know.
other than that once you create the functional module in se37 make it RFC enabled , and once you import the RFC model , you can give your ECC system user name and password and search for RFC you have created from the list of RFC.

Settings SLD and JCO connection for Java Web Dynpro

Hi BI Gurus,
I'm a Business Intelligence newbye and I'm a bit confused about Web Dynpro configurations.
I try to execute, through Netweaver Developer Studio 7, a simple java Web Dynpro who call the standard Flight List BAPI.
My configuration is: NW 2004s installed on BI server (with java instance and j2EE Server) and Flight List BAPI stored on R/3 ECC. 5 System in another server.
Now, my doubt are:
1) in SLD Data Supplier (J2EE Visual Admin on BI Server) CIM configuration, what are the connections parameter necessary?The BI host or R/3 host?
2)if I set BW system parameters in SLD and in NWDS when I try to run my simple web dynpro an error occour This is the output:
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
3)where can I create new JCO connections?What are the requirements settings?
I am always available for answers about the post!!
Help me please!!
Thanks thousand and sorry for my incorrect english!!

Andrea,
You can Create the JCo destination from Content Administrator. You must login as Administrator.
use the link as
http://<server>:<port>/webdynpro/welcome/Welcome.jsp, select Content Administator->Create JCo Destinations/Maintain JCo Destinations.
Please have a look on the following links regarding creating/maintaining JCo destinations. The are usally asked questions regarding JCo destinations.

Can I connect to Oracle server7.1 through Java-JDBC using the latest thin drivers???

Hey Gurus,
Please help me .
MY Current requirement is to connect to multiple oracle 7.1( and other variants) servers running on different operating systems, through Java/JDBC.
My FIrst question is, can i connect to older versions of database using latest drivers?
I could connect to the server running on SCO-oracle 7.1 using SQLNet8.1.7 under windows. But the same is not happening when the client is on Linux.But I need to connect from linux
It says ORA-03113 - End of communication channel.
What may be th problem.
If any one could show some pointers where I can get more information about this problem would be helpfull
THanks
Lokesh

I tried the classpath suggestion above (not the one modifying the .xml file) , but it didnt work for me , I am using WLI 10.3.1 and trying to connect DB on 8.1.7 V . I downloaded the classes12.jar and the ojdbc14.jar file from the oracle and placed in lib and the even included the classpath , but i again got the same exception .
All this while i was selecting the option Oracle Driver Thin from the DataBase Driver when creating the connection pool from console . I tried with "BEA Oracle Driver (Type 4)" and it worked for me .. Although the option "BEA Oracle Driver (Type 4)" lists only the DBs from 9.0.1 to 11 G , but in my case using this driver i am able to connect to Oracle DB 8.1.7 . So all you guys if it classpath doesnt fix the issue try out by selecting Driver , "BEA Oracle Driver (Type 4)" .
Manoj , this will fix the Connection pool part of the ques, but for the java part Try to load the Driver class "weblogic.jdbc.oracle.OracleDriver" before connecting to DB with Class.forName.
Thx

How to call legacy system screen in web dynpro for java?

Now I'm using Netweaver CE for building BPM (Business Process Management).
In BPM system, I wana call legacy system screen(ERP, C/S , Web, etc..) in web dynpro.
I'v already known how to call legacy system method and data.( using RMI, SOAP and RFC )
But I don't konw how to call legacy system screen.
If there is no way calling legacy system screen, I will have to build every screen using web dynpro.
It's so terrible.
So I think there is a way calling legacy system screen.
It's just my opinion.
If It can call legacy system screen in web dynpro, please let me know how to call it.
Or, If there is no way calling legacy system, how solve I this problem?
Thank you reading my question.

I assume that with "legacy system screen" you mean ABAP Dynp sceens. Of cause it would be attractive to integrate into new BPM processes. However there is a conceptional issue: You could easily integrate them e.g. into a WebDypro using a URL to to the so-called WebGUI (the ITS that makes Dynp screens Web enabled).
However the Dynp screen store all there state in the ABAP backend. This information is not available to to the process engine, e.g. to set the Task to completed or to use the data in Output Mapping.
In fact you need a way to wrap the how UI transaction into a WebDynpro screen including data flow.

JAVA, JAVA WEB dynpro and possibility of JAVA workflow

Hi all
Just a take here -- I'm just getting some feelers on the way WF SHOULD be going in future.
Since starting to use the JAVA WD system and netweaver developer studio it seems that having to encapsulate a lot of NEW Workflows as ABAP objects is going "Backwards". (Note I said NEW not EXISTING applications)
I understand that some compatability with existing systems needs to be maintained but if your user is doing all his applications from a Portal you really need the WF's to be triggered from the portal via say WEB SERVICES.
I find I'm actually using the older ERP / ECC 6.0 R/3 systems these days purely as DATA repositories and from a JAVA program can often retrieve the data via standard BAPI's and RFC calls in a JAVA or Portal application.
Isn't it about time that the workflow system as a whole was made much more JAVA and PORTAL friendly --since this is where more and more people are doing their developments from.
Since switching more or less full time over to JAVA WEB DYNPRO developments the whole development time is completed MUCH QUICKER and with many many less mistakes.
ABAP Web dynpro is also OK but it's still a little bit of a nightmare compared with JAVA when you need a lot of WEB SERVICES.
Some WF's obviously will need to remain ABAP based but newer custom WF's IMO should be WEB DYNPRO and WEB SERVICE based.
I can't think of too many large organisations who aren't making more and more use of Portals these days -- so C'mon SAP -- provide some proper Web hooks into WF's instead of us having to go through hoops and rings of writing LAST CENTURY's code to get stuff to work through a Portal.
Cheers
jimbo

Hi,
Have you checked the new BPM tool that SAP is offering? I think that it is definately a big step into to the drection that you are describing. I haven't really checked all its features and the technology that is is based on, so I am not the biggest expert of this matter.
Check for example this article to get an overview: http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b06c49b2-ac63-2c10-3d8d-d17b817ba4ca?quicklink=nw-bpm&overridelayout=true
Of course it will be a long road before this new tool will (if it will ever) replace the old ABAP based workflow engine.
I wouldn't totally agree with all the points that you presented (ABAP WD being a nighmare, etc.). Actually I think that the direction (at least in some parts) is the opposite. For example SAP seem to have replaced their "old" travel management applications (Java WD) with new ABAP WD applications, so I see that they believe more in ABAP than Java (of course there might be some financial & other reasons behind this also.). In my opinion WDA has so many advantages compared to WDJ, that I would consider carefully the options when choosing the technology (the possible better(?) compatibilitly with web services might be one of the reasons).

Karri

Sending java web dynpro interactive form as pdf attachment from Business WF

Hi,
I have a java web dynpro application with interactive form(online), on send button click i need to send the filled form as an PDF attchment to internet mail id. I am using SO_NEW_DOCUMENT_ATT_SEND_API1 inside workflow to send attachment. My custom RFC which is interacting with WD app is getting the pdf source context attribute(simply i set the import parameter with that attribute and no juggling is done) as import parameter which is of type XTSRING. Once i execute the application i am getting mail with attachment as pdf but i am not able to open the pdf. It is of just 1 KB size. It seems my pdf source context attribute is not sending data. Can some one suggest how can i solve this.DO i need to convert the data to pdf format before sending or any otgher thing i need to do.
Regards
Ravindra

I did that before posting the question itself (enables = false), it doesn't work. It just disable the extra features like digital signature and stuff. Interesting thing is all our HCM forms developed for HR actions works fine with out any issues. Why the interactive form developed with WDJ is not working and it requires credentials??. The same form works fine if I deploy the application directly into server but it throws the error if I check in through NWDI ..
If you look at the server location it has the file but it throws the error:
Caused by: com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.base.core.PDFDocumentRuntimeException: IOException occured while creating template stream from the TemplateSource : .\temp\webdynpro\public\sap.com\ess~ben\webdynpro\Components\com.sap.xss.hr.ben.reviewtable.VcBenefitsReviewTable\ReviewTableView_InteractiveForm_Review.xdp (The system cannot find the file specified)
Please advise.
Thank You,
Hari.

Convert JAVA Web Dynpro to ABAP Web Dynpro application

Hi,
I was hoping someone could tell me if there is a way to port a JAVA Web Dynpro application to ABAP Web Dynpro. We have some JAVA WD apps that would now make more sense to have running on our ABAP system so we would like to convert them to ABAP WD apps.
I know the theory is that WD is metadata/XML based so it should be possible to port the WD definition to ABAP and have the ABAP runtime generate the application again in ABAP. I expect that any custom code that is written in JAVA would need to be manually rewritten in ABAP - but it would be great if there was tool or method to at least port the majority of the application.
Thanks in advance for your help,
Simon

Hi Simon
You are correct in thinking that all WD apps are based on metadata, but unfortunately, the similarity between WD Java and WD ABAP is just a conceptual one, and no such tool exists to convert one to the other.
In addition to this, there are certain implementation differences between ABAP and Java that mean you could not convert one to the other. For instance, the whole concept of model objects does not exist in WD ABAP. Therefore, structural entities used in WD Java such as model components could not be tranlsated into anything that exists in ABAP, because the concept is redundant in the target language.
Sorry about that, but Java and ABAP are sufficiently different beasts that such a tool is not possible.

How to create table in interactive form via Java Web Dynpro

Hi,
How to create table in interactive form via Java Web Dynpro ?
Any online tutorial / example ?
Thank you.
Regards,
Eric

Hi Eric,
Just choose the UI element Table from Form Library and drag and drop it on the form. now choose the no. of rows and columns and other settings you want about table from the wizard initiated through this process. This all is what you have to do to create the table. Now to bind it to the fields of the data source bind the individual colums to individual attributes of the node in the datasource.
Hope it will solve your query.

Append Data from Java Web Dynpro to an Internal Table in ECC

Hi,
Currently I am using AdaptiveRFCModels to creating/updating records from Java Web Dynbpro to FM in R/3. Users can add few records before they save the changes. The current design is Java Web Dynpro call RFC FM when user add/edit one record. The record will store in an global internal table in the Function Group. For example, I have added 3 records before I save the changes. It means that global internal table should have 3 records that I added before I save it. But in fact, the global internal table only store one record while I adding the third record. The global internal table not able to keep the previous records. The code below is how I code to execute the FM from Java Webdynpro. Is the code can work as I expected? Anything missing in the codes? Please advice. Thanks.
wdContext.nodeZhr_abc_Input().bind((Zhr_abc_Input) model.createModelObject(Zhr_abc_Input.class));
Zhr_abc_Input objReq = new Zhr_abc_Input();
Zhr_Pad31 insUpdVer = new Zhr_Pad31();
insUpdVer.setQ_Id(wdContext.currentContextElement().getQ_Id());
insUpdVer.setZ_ce(wdContext.currentZhr_Detail_OutputElement().getZ_ce());
objReq.addLt_Pad88(insUpdVer);
wdContext.nodeZhr_abc_Input().bind(objReq);
wdContext.currentZhr_abc_InputElement().modelObject().execute();

According to your code you are setting only one record.
You have to create 3 elements for each record and add all the three to the nodeZhr_abc_Input node.
If I understand correctly, node currentZhr_Detail_Output is the one which is containing all the three records. Loop through this node, pick each record and set to the input node.
wdContext.nodeZhr_abc_Input().bind((Zhr_abc_Input) model.createModelObject(Zhr_abc_Input.class));
for(int i=0;i<wdContext.nodeZhr_Detail_Output().size();i++)
Zhr_abc_Input objReq = new Zhr_abc_Input();
Zhr_Pad31 insUpdVer = new Zhr_Pad31();
insUpdVer.setQ_Id(wdContext.currentContextElement().getQ_Id());
insUpdVer.setZ_ce(wdContext.nodeZhr_Detail_Output().getElementAt(i).getZ_ce());
objReq.addLt_Pad88(insUpdVer);
wdContext.nodeZhr_abc_Input().addElement(objReq); // Changed from bind to addElement
}//for end
wdContext.currentZhr_abc_InputElement().modelObject().execute();
Note: I just typed the code. Syntax might be wrong here and there. Please correct it while coding.

Problem in calling XI generated Web Service via Java Web Dynpro

Hi experts,
I have problems with calling a web service, which was created by XI. I have already tested the web service with Altova XMLSpy. The Web Service works fine.
But when embedding this web service into Java Web dynpro application no message flow is given. I have two views one Selection View and one Result View which should show the answer sent by RFC-Call.
<b>My Settings in NWDS:</b>
During configuration of web dynpro I have choosen 'Import adaptive Web Service Model' --> Select wsdl file via local file system --> 'no logical destinations - use WSDL URL for metadata retrieval and web service execution'.
The model is also not shown in diagram view although I have added into the diagram.
The web service was created on XI 7.0.
Should I do any other settings e.g. in Visual Administrator, Web Dynpro Content Administrator?
So can anybody help me.
Thanks a lot.
Regards,
Mario

Hi Aviad,
thanks for your fast reply.
But in Web Service Navigator my Web Service is not shown, because I used the SOAP Adapter.
<b>My Web Service link:</b>
http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SRV_GBD_WS_GET_DEB_DETAIL:CC_GBD_WEBSERVICE_SENDER&version=3.0&Sender.Service=&Interface=%5E*
During executing Web Dynpro I got following errors:
1. 'The system cannot find the path specified'.

Using Java Web Dynpro iViews to integrate with SAP MDM

Hi,
I have already SAP MDM 5.5 supplied iViews with Enterprise Portal.
These include itemDetail iView, ResultSet iView, PicklistSearch, Hiearchy Search.
Now, I am integrating Java Web Dynpro iViews with SAP MDM.
When adding the fields using object of ResultSetDefinition Class, should we use MDM Table Name or MDM Table Name Code/MDM Field Name or MDM Field Code?
I think we should use the CODE as the name as it does not contains any space while working with Java API.
Regards
Kaushik Banerjee

Hi Kaushik ,
Yes you should use the Field and Table CODE when integrating MDM with any other system using API either Java, Abap or Com api.
Actually this is one of the main use of the code in MDM .In API.
Hope It Helped
Thanks & Regards

R/3 search helps in java web dynpro

Hello,
A customer of ours has some Z transactions in its R/3 system, which basically present a very simplyfied version of MIGO. This Z transaction makes extencive use of Search Helps, which in some cases have been extended.
A ABAP developer with some Web Dynpro experience showed me that it was easy to integrate these search helps into his web dynpro application.
I cannot find how to do this in java web dynpro with the developer studio. Is this possible and if yes, how?
Greetings, Walter.

Hi Walter,
You can use search helps in Web Dynpro for Java also. The feilds with check table in R/3 automatically give search helps. To provide explicit search help you need use EVS or OVS.

Java Web dynpro with ABAP Clients?

Morning,
We have a situation where we would like to use a Java Web dynpro with multiple ABAP backend data sources. This is for autorization as well as data. We are not using Enterprise Portal.
We've created a pair of system Jcos and mapped them to the Web dynpro via the URL. This works and the correct data from the correct Client is retrieved depending on which pair of Jcos we define in the URL.
The problem we are having is that we are only able to logon using the ABAP Client defined in the ume....master.client parameter.
Is there a way to achieve this (again without EP) either in the system configuration or programatically in the web dynpro?

Hello,
Thanks for the updates. Actually my query is we have a SCM 5.0 system which has a java stack in it. But now we are going to upgrade it to SCM 7.0. - Is SCM 7.0 has a java stack ?
If it doesn't have , can we upgrade SCM 5.0 to SCM 7.0 without Java Stack ? Is it posssible to upgrade without Java Stack or not ?
Is it possible that we can convert Java Stuff into ABAP web dyn pro ? If yes , how shall we can achieve it ? If not, how shall we proceed in an alternate way ?
Thanks for your help in advance.
