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.

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.

Call webdynpro java Web Service from ABAP

Hello,
This is regarding calling portal web service from ABAP.
1. created web service in NWDS and deployed it to portal server
2. created abap proxy to call this web service from abap SE80 transaction
3. created logical portal for the above proxy LPCONFIG transaction
this is working perfectly. the web service is getting called from abap and funcitonality is working
but my doubt is we have no where given the login password for portal server in the abap system
then how come it works without login password
if i run this web service directly from portal in wsnavigator, then portal login is required.
If we want to incorporate authentication then how to do that ?
thankyou,
B

When you are testing the application in SE80.
Is it ot asking for the user id password.
I created a similar service and for me its asking for user id and password.
Go to SM59 and there look for a RFC destination of type HTTP Connection to External Serv. usually will be named as
SAP_PROXY_ESR.
for this connection check the logon and security tab.
may be some user id and password is given there. means hardcoded.
thanks

Calling ERP Web Dynpro from CRM Opptunity with parameters

Hi, experts!
In CRM7.0, I'm calling ERP Web Dynpro from CRM Opptunity.
We've added a button in Opptunities and the buttom can navigate into ERP Web Dynpro.It works fine.
Now, I'm trying to move the value of Opptunity ID to a field in ERP Web Dynpro when we push the buttom. That's a problem I want to solve. We're struggling to move the value, but it doesn't work.
We uses the following settings:
1) We call Z- Logical Links generated by Transaction Launcher when we push the buttom.
2) We define Transaction Parameters in a Transaction Launcher Wizard(Step5). We've set "//clipboardBTOrder/BTOrderHeader/OBJECT_ID" or "//datacontextCURRENTBT/BTOrderHeader/OBJECT_ID".
But both of them doesn't get any value.
3) If you set SYST data or constants in Transaction Launcher Wizard(Step5), you can find the data in ERP Web Dynpro.
Does anyone know which parameter gets the value of current opptunity data?
Or if you have any tips to create URLS using programing, could you please share the information with me?

Does anyone have tips??

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?

Cheers,

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.

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.

Calling external web service from ABAP Program

Hi All,
Can somebody point me to the documentation where how to call an external (3rd party) web service from ABAP program is explained?
Thanks & Regards,
-Smita

which version of R/3 you are using. if you are on was 6.40 its very simple, there are delivered tools to generate client proxy for consuming webservice. if you are on wa 6.20 you can use cl_http_client to achieve the same. check out the following weblogs.

The code will allow you to call the stockquote webservice using GET

Your code is missing the request uri which is needed in a GET call.

Calling java web service from another webservice app

Hi,
I am newbie to writing java webservices and also new to weblogic workshop environment. Our company already has an web-service application (not written by me) that basically receives soap messages M1(e.g. with fields A,B and C) and does a function. The format of the message is defined in .xsd file and the application also has .wsdl and .jws file.
The modification now required is that this existing application will keep listening in port p1, but another copy of the same application will run in port p2. So i have to write a webservice code in weblogic workshop that basically recives message M1 and forward the message to port p1 or p2 depending upon field A=0 or 1.
Message M1 ---->New Application
|->forward to application running on port p1 if field A=0 in message M1
OR
Message M1 ---->New Application
|->forward to application running on port p2 if field A=1 in message M1
Please give me some example code/suggestions that i can start with. i am already starting to get a bit worried because i have to finish it in next 3 days and i don't have much experience with it.

Hi Gianluca,
here there is a little sample to implement a web service Proxy class that invokes a service from a Descriptor file.
http://help.sap.com/saphelp_nw04/helpdata/en/6c/8aac34d2d6e64dbcfc3ffb10bb3e9e/frameset.htm
Take care with SAP WebAS (Soap Runtime) and Apache Web Server. If the web Service is published on AXIS 1.0, SAP Soap ABAP runtime and AXIS 1.0 Soap Runtime aren't compliant.
You could migrate the Java application from AXIS 1.0 to AXIS 2.0.
If you need, don't hesitate to contact me!

but when i am using my url at the end of step 3, i am getting error as follows:

thanks in advance

Hi SDS,
you recieved a http 404 error when trying to access the Sharepoint Web service. Http 404 indicates that the resource is not reachable (cf. HTTP 404 - Wikipedia, the free encyclopedia). There could be different reasons for that. I'd suggest rubble checking the URL of the Web service first. Try to access it from a browser on you desktop. If the URL is correc. Most likely the SAP system is not able to connect to the URL. This could, for example, be due to some firewall restrictions. You should ask a SAP Basis colleague if they are able to access the URL of the Web service from the server on which the SAP system is running.
