JAVA webservice to ABAP Webservice

Hi,
There is a Webservice developed in Java and published.
The same webservice we are now develping in ABAP. Though there is no change in the functionality of the webserice, the WSDL generated for ABAP webservice is looking different than the one for JAVA. How to resolve this issue? I do not want to ask the service consumer to regenerate the Clinet Proxy for the new WSDL.
Could you please help me in resolving this issue?
Thanks & Regards,
Kishore Babu T

Hello Johannes,
Which WSDL do I need ? In the wsnavigator I can choose RPC or Document, and then Default or SAP_WSDL to download the WSDLs.
Try this: [Accessing a Service|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/b8/a3cca166d440c29931c0c5494c32e5/frameset.htm]
And do I need to publish the webservice (which I want to consume) on the Java stack ? or ist it already published when the wsnavigator can access it ? (the service resides on the Java stack, and I want to consume it from the ABAP stack from the same system)
In short, no. You can safely use the Web service without publishing it - as Olivier explained, you need only the WSDL.
The "publishing" term is usually used when you register (publish) a Web service in the UDDI server or the Services Registry. Publishing is only relevant if you want other people to be able to locate the registered service in the UDDI server.
Hope this helps,
Rossen

Using Java Webservices provided by xRPM 4.0 in PPM 5.0

Hi,
We have developed some custom WD ABAP applications in PPM 4.5 which were using Java webservices provided by xRPM 4.0 to get the UI context.
The details are provided in the document
https://websmp109.sap-ag.de/~sapidb/012006153200000315412008E/How_to_xRPM_custom_iView.pdf
We have upgraded to PPM 5.0 and the custom webDynpro application is not able to fetch the UI context and get the portfolio GUID. I have verified that the RFC destination and Logical port required to call Java webservices is maintained as mentioned in the above document.
Are these SAP standard Java webservices available for use in PPM 5.0 ? Please let me know if we need to change the custom code to fetch the UI context in PPM 5.0
Thanks,
Yomesh

Thanks Amit for the confirmation. I am following SAP Note 0001399319 which mentions about how to develop for custom WD ABAP applications in PPM 5.0.
The example WDA component mentioned in the note is /RPM/CUSTOM_COMPONENT. I am developed a custom WD ABAP application in lines with the SAP note and still not able to get the GUID in the context.
The code written in WDDOINIT of these applications is as below,
instantiate session state class
    wd_this->mr_session_state = cl_inm_session_state=>get_instance( ).
Obtain current context from session state.
    CALL METHOD wd_this->mr_session_state->get_current_context
      IMPORTING
        es_context = wd_this->ms_context.
I am getting null in ms_context.
Please let me know if you have tried to implement an custom WDA application in PPM 5.0. Not sure what am I missing in the above scenario.
Thanks,
Yomesh

Problem while Consuming Java Webservice from WCF client

Hi,
I am trying to Consume Java Webservice from WCF client.The webservice main functionality is digital data management.The client can Query Digital data and upload digital data by calling webservice methods.Problem is when i am trying to call webmethod from WCF client its giving "Unrecognised message versions".I have no idea about how the message objects are processed at serverside.but at server side they have used JAXP for XML document parsing.
The response content type is Multipart/related and applicatio/XOP+XML.
Can u plz help me how to handle this situation.I have minimum knowledge in Java WS architecture.Basically i am .Net programmer.
Can U please guide me in a proper way to resolve the problem.

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks

Formating the response of Java webservice to table structure in webdynpro

Hi All,
I am stuck at a point where I have a Java Webservice resulting an ArrayList Response.
My webdynpro will have to populate the ArrayList response into a table.
Below is the piece of code am using to execute my webservice.
CODE :
JavajdbcModel md = new JavajdbcModel();
    Request_Display reqDisp= new Request_Display(md);
    try
    reqDisp.execute();
    wdComponentAPI.getMessageManager().reportSuccess("Str: "+reqDisp.getResponse());
RESULT :
<modelObject class="Response_Display"><target roleName="DisplayResponse"><modelObject class="DisplayResponse"><attribute name="Response" value="[[i01111, USSS, DSGTechTwo, DEF], [i012345, USSS, DSGTechOne, ABC], [i067890, USSS, DSGTechTwo, DEF], [i07777, USSS, DSG, ggg], [i08888, cccc, vvvv, bbbb], [io3333, USSS, DSGTechOne, abc]]"/></modelObject></target></modelObject>
The required output are the values that are with the blue font above.
I have tried with methods like :
getAttributeValue, getResult - but are of not much help.
Could you please help me out in this.
Thanks & Regards,
Suyukti. B N.

Dear Suyukti,
Since your web service returns an arraylist,
you need to retreive the response into an arraylist. Then you can you this arraylist to populate the node for the table as required.
Your code will be something like
ArrayList al = (ArrayList)reqDisp.getResponse();
Now that you have the response, then use the get function of the arraylist to set the context.
al.get(index);
This function returns java.lang.Object, so you need to to cast into the required type.
e.g. String str = (String) al.get(0);
Hope that works.
Regards,
Mayuresh.

Problem using VB Client with a JAVA Webservice

Hi people!
I'm using JDeveloper (9.0.3) to create a JAVA Webservice on OC4J container. I followed tutorial of Oracle and I got to execute my webservice, including I can invoke my methods by HTTP using HTML forms.
I need to invoke my methods using a VB Client with MIcrosoft SOAP ToolKit. My VB code is:
Function autenticar(login As String, senha As String)
Dim ObjWS As New MSSOAPLib30.SoapClient30
Dim retorno As Variant
Call ObjWS.MSSoapInit("http://10.71.200.40:8888/iSimp-Web-Root/br.gov.anp.isimp.controleVersao.ControleVersaoEJB?WSDL")
retorno = ObjWS.autentica(login, senha)
autenticar = retorno
End Function
My webservice publish a method called autentica that receives two parameters (a login and a password) and authenticates to obtain access to my system.
When I try to execute this function, I got this message error:
No deserializer found to deserialize a ":login" using encoding style "http://schemas.xmlsoap.org/soap/encoding/". [java.lang.illegalArgumentException]
Anyone knows what is this error?

If you could post what solved your problem that would be useful for others that run into the same issue. Thanks if possible!

Creating Java Webservices.

Hi ,
I have a Client WSDL. I have to create a dummy service java webservice uisng that wsdl.I have used axis WSDl2Java utility to create java files from the WSDL .How can I create a webservice using these java files?
Thanks,
Vivek

This doesnt make much sense. Where did you get the wsdl from if you dont have a web service?
When you develop a web service, your wsdl can be create by:
1. when running wsgen
2. when you deploy your web service (on Sun App Server 9.0)
Once you have your wsdl, you can create a client that actually uses your new web service.
I dont think you can go 'backwards' by starting with a client and a wsdl and then create your service. However, there could be some wizard/tool out there that creates a "stub" web service that has no guts.

Creating Java Webservice

Hi All,
I am trying to create a w/s in java with MDM at the backend. I have posted the query on MDM Forum. Following is the link:
Creating Java Webservice
Please see if you can help resolve the issue.
Regards,
Nitin

Hello Nitin,
For using MDM API into beans you need follow these steps
1)create an external library project
2)add all the jar files in the that project
3)Create Publica parts for those jar files
4)Build the project
5)Add the reference of the extenal library project(public parts) into the Bean project
6)Create EAR project for the corresponding bean project and deploy the EAR project
7)Use this bean class in the webdynpro project
8)Also add the reference of the ear project in webdynpro project
9)Build and deploy webdynpro application after writing entire logic, and then chek the output.

How to use Delphi Client in Java WEBSERVICE

I am building a Webservice Application. In client side I use Delphi to import WSDL from a Java Webservice Server ( literal WSDL ). By using WSDL Importer Control I successfully imported the WSDL file but when I called the impoted method the system returned an error :
"Project sendEmail.exe raise exception class ERemotableException with message ' Unable to find a matching Operation for this remote invocation <SOAP-ENV: send xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> </SOAP-ENV:send>.Please check your Operation Name.'
I think when i call send method in Client side the request is sent to Webservice Server but in server side ( build in Java ) that method doesn't match with the original method ( although the method in client side is imported from Webservice Server )
( When I use Delphi client to invoke methods from Delphi Webservice Server ( with rpc WSDL ) the result is OK and Java client also sucessfully invoke that method from Java Webservice )
Can you show me how i resolve this problem. Thanks

Hi Robin,
At some point, you can expect that the Web services frameworks will be implementing some of the plumbing related to WS-* for you. For example, you can rely on the framework to deal with WS-sec for you with the current Developer Preview of OC4J. For WS-Adressing specifically, you have to handle this in the application layer today, and there is very little the framework can do for you, other than converting the WS-Addressing SOAP header into some java object model for you. The business logic related to the use of the ws-addressing headers has to be implemented at the application level, with some handler. The same applies today for any JAX-RPC based Web services framework, including Axis. Now, if you are using some 'advance' framework like BPEL PM, they can do a lot of heavy lifting for you, under the cover.
Hope this helps,
Eric

Non Java Webservice client Authentication

I see in the Weblogic docs many examples of Java webservice clients. Including
one that passes a user id and password through the getXXXPort(userid, password)
call for authenticating the user at runtime. My question is, can a non Java webservice
client authenticate itself in somewhat the same manor? A non Java client wouldn't
have the client jar file available containing the stubs and all.
If someone has a code snippet they could send me it would be most appreciated.
Thanks,
Craig Lindley

Hi Craig,
An partial example using .NET is attached; in this environment you need
to use their NetworkCredential class.
Hope this helps,
Bruce

Deployment of Java WebService with OC4J and JDeveloper

Hi,
I have created a sample java webservice following instructions given in one OTN tutorial (Developing, Deploying and Managing Web Services Using JDeveloper and Oracle Application Server ) at http://www.oracle.com/technology/obe/obe1013jdev/ws/wsandascontrol.htm
We were able to create the webservice as shown in the tutorial but are facing problem while deploying it. The deployment message console in JDeveloper shows one "Deployment failed : ClassCastException".
Some of the lines from Jdeveloper console are ::
"Binding WebServices web-module for application JavaWebService-GetDates-WS to site default-web-site under context root JavaWebService-GetDates-context-root failed"
I have gone through the stack trace in the OC4J console but couldnt figure out much out of it as all the culprit classes are from different jar files...Here is the Stack trace for your ref::

2006-05-05 19:07:12.713 WARNING java.lang.ClassCastException
I am using J2SE1.4.2_08 version. Earlier when I used java 5 version I got an error something like "Found runtime environment 49.0 expected environment is 48.0"....so I moved over to J2SE1.4.2_08 version but now I am getting above error as shown in the stack trace.
Looking at the success message shown in the OTN tutorial it seems that only step that failed while this deployment is Initialization of servlet : Oracle.j2ee.ws.server.JAXRPCServlet for webapplication Webservices.

Hi, thanks for your quick help.
Shay, I agree with you that the specific tutorial uses JDeveloper 10.1.3 and I need to use JDK 5 to run that version of JDeveloper.
Earlier when I used JDK 5 with JDeveloper 10.1.3, I got different error saying "Found runtime environment 49.0 expected environment is 48.0".....so I moved over to J2SE1.4.2_08 version but now I am getting an error as shown in the stack trace given in the very first post to this thread.

Java Webservices

Hi all,
I am new to java webservices.But i need one solution in webservices.
I want to get SOAP information from WSDl url( If i give like this.. http://wslite.strikeiron.com/phonenumberinfolite01/PhoneNumberInfoLite.asmx?WSDL).
Is there any tools like NuSoap is available for java or is there any other methods to get it??
plz anyone guide me..
Thank you..

Hopefully the main server infrastructre can be developed using a server like TomCat Yes
Can somebody refer me to some good books on this topic.Just check the amazon user reviews dude. If you stick to JAX-RS, I learned that in under a day without needing any book at all, its THAT simple once you get over the initial setup.
Speaking of which: you should not be thinking about building anything at all until you've learned core Java - not only the language but also the tools, the platform and the important JDK classes (collections, threading, dates, sockets, ...).
http://docs.oracle.com/javase/tutorial/
You're going to be horribly confused until you can deal with classpath issues, know how to bind library jars to your application, you can read and interpret exception stacktraces and you know how a Java application is packaged.

How to call java webservice from plsql procedure.

Hi,
Could any one please provide any reference document for invoking a java webservice from pl/sql procedure.
regards,
Venkat

Hi,
There are basically various platforms where u develop the code with different patterns, though the idea is same everywhere.
1. If you want develop a Java Client to call a WebService from NWDS then Pls refer >>
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/cb2e29578c0262e10000000a11466f/frameset.htm
Note: By default the WebService developed under NWDS is Document Based WebService (i.e. In WSDL the style element would be 'document')
2. If you want to call a WebService from the platform other than NWDS than, Sun's official site would be the best choice to go for.
Pls refer >>
http://java.sun.com/developer/technicalArticles/J2EE/j2ee_ws/#design
Would appreciate if you reward the points if the answer is helpful.
