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.

Calling java web dynpro from ABAP

Hi!!
I have a double problem!
First I want to call a java web dynpro application from ABAP. I managed to do it using :
call method cl_gui_frontend_services=>execute
exporting
document = url
exceptions
others = 1.
Where url is the java application url with parameters. It's working...
...but here comes the second problem : i need SSO So first solution is not sufficent.
Can anybody help?

Ok looking for the solution i figure out that it won't be possible anyway, i need a first log to the portal in order to issue a logon ticket before any attempt of SSO authentication.

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.

Why not "Web Dynpro *with* ABAP"?

As a newbie I found "Web Dynpro for ABAP" to be confusing. Any ideas why its worded that way? Just curious.

Hi,
because it's a programming model created for abap programming.
If you look at the true content of webdynpro you come out at:
declarative programming of all the navigation, ui, datadisplay and gathering, without
writing the code, but letting the code to be generated.
so it's a concept build for abap,
not with abap (although the classes and interfaces are)

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.
These are the tutorials

Error when calling Java Web Services from ABAP.

Hello experts:
    In my project, I will call Java Web Services with ABAP coding. With WSDL, I generated a proxy class and created a HTTP connection (t-code: SM59) and a logical port (t-code:lpconfig) for this proxy class. But when running, I would receive the folllowing errors:
   SOAP:1.023 SRT: Processing error in Internet Communication Framework: ("ICF Error when receiving the response: HTTP COMMUNICATION FAILURE")
   If I used HTTPS, there is no problem.
Regards
Bob

Hi Bob,
It might be the possibility that your java web server is configured to listen only on HTTPS.
If your HTTPS is working fine, then first check with your JAVA server for HTTP connectivity, then try it calling through ABAP.

Piyush

Web Dynpro for ABAP and Floor Plan Manager

Hi.
How can I integrate an ABAP Web Dynpro application in the Java Web Dynpro based Floor Plan Manager (FPM) framework? I'm thinking of the "General Information" page in the MSS Business Package (com.sap.pct.erp.mss.general_information), where the manager use the Employee Search iView com.sap.pct.erp.mss.generalinfo_employeesearch based on the Java Web Dynpro application sap.com/mss~eepro.GeneralInformation to select individual employees.

PdfSource content of interactive form in Java Web Dynpro

Hi All,
I am using Java web dynpro with interactive form. When I display the contents of the pdfSource of the interactive form into a text file, I see the following which is not a true binary content. Could u please let me know why the content is represented in the form other than binary?

Hi Naidu
I have written the contents of the pdfsource to a file in the server using the below code:
byte b[] = wdContext.currentContextElement().getPdfSource();
File file = new File("C:
Severance.pdf");
long length = file.length();
FileOutputStream os;
try {
 os = new FileOutputStream(file);
 os.write(b);
 os.close();
catch (Exception e)
 // TODO Auto-generated catch block
 wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("Some Exception "+e);
 e.printStackTrace();
And i have added a File Download element in the Application and have implemented the below piece of code for it:
IWDAttributeInfo attInfo = wdContext.currentContextElement().node().getNodeInfo().getAttribute("ctx_downloadpdfsrc");
ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();
IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;
binaryType.setMimeType(WDWebResourceType.TXT);
String fileName ="C:
Severance.pdf";
// path to the source file
/* converts the binary file to a byte array and moves it to the text element */
try
 File file = new File(fileName);
 FileInputStream in = new FileInputStream(file);
 ByteArrayOutputStream out = new ByteArrayOutputStream();
 int length;
 byte[] part = new byte [10 * 1024];
 while ((length = in.read(part)) != -1)
 out.write(part, 0, length);
 in.close();
 wdContext.currentContextElement().setCtx_downloadpdfsrc(out.toByteArray());
catch(Exception e)
 wdComponentAPI.getMessageManager().reportSuccess(" !!!!!!!!!!!!! "+e);
 throw new WDRuntimeException(e);
Other than this, if we simply write this line in the code it will display the entire content of the pdfSource on the screen when deployed:
wdComponentAPI.getMessageManager().reportSuccess(wdContext.currentContextElement().getPdfSource().toString());

Jyoti

ABAP Web Dynpro V/S JAVA Web Dynpro

We need to pick developing technology between ABAP Web Dynpro v/s JAVA Web Dynpro. Is technology better than other in terms of security, scalability? There is lot of documentation on the web but it is very old and out dated. I am pretty sure things have changed quite a bit with recent versions of SAP. Any feedback is greatly appreciated.
Thanks.
PS: I Used Web Dynpro for ABAP at my previous client for SAP SRM without a problem.

Dear Sap Fan
This has been a long and interesting debate on SDN.
You will find plenty of posts discussing this matter.
But there's no clear winner, I warn you.
;o)
This one in particular is very good:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/e0e4940c-035c-2b10-0b9d-eb8f99674f4e]
But you can also check these others:
[webdynpro java or abap;
[Webdynpro Java or ABAP;
[Webdynpro Java or ABAP;
[Webdynpro Java or Abap ?;
More and more you see clients migrating from WD4J to WD4A.
Guess SAP is also heading into that direction, perhaps because Oracle bought SUN sometime ago.
I'm comfortable on both environments I have to say.
I have more than 10 years with development.
I know ABAP from inside out.
I also know JAVA and I'm certified with this technology.
But I personally prefer WD4A.
Why ?
Because you don't need to use NWDI.
Because you don't need to configure JCO's.
Because you integrate seamlessly the development with the transport framework (requests, etc..)
Because debugging is great.
Because plenty of traditional ABAP tools (trace, logs, performance analysers, etc..) can also be used with WD4A
Because you don't need to worry with NWDS...just type SE80 and you're there... ;o)
And I could go on and on....
But then again, it all depends:
Do you have a lot of good in-house JAVA knowledge ?
Do you use a lof of Custom JAVA development in your company ?
Are you planning to use standard SAP (ESS/MSS or others for example) ?
I'm not saying that WD4A is "better" than WD4J.
There's no such thing.
Each option has its pros and cons.
You also can't tell that WD4J is more secure or scalable than WD4A. Or the opposite.
And, believe me, WD4J is still going strong with a lot of customers.
But things are changing, and for me WD4A would make more sense if you want to be aligned with SAP.
Now and in the future.
Kind Regards

ESS Business Package for ERP 6.0 is a ABAP or JAVA Web Dynpro

Hi,
We are trying to implement ERP 6.0 and ESS with the Portal.
Is the ESS business package a ABAP or JAVA Web Dynpro????
Thanks.
Regards,
Mike

Hi Mike,
ESS BP is a portal content (runs only on portal runtime) which can only be deployed and run on SAP J2EE server (So it is java based).
http://help.sap.com/saphelp_erp2005/helpdata/en/f6/263359f8c14ef98384ae7a2becd156/frameset.htm
From EHP2 for ECC 6.0, you have an option choose ABAP WebDynpro for Travel related services. However, the portal content (iViews) is still on SAP J2EE server.
Thanks

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

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 consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you
Best Regards
