Java Webservice Falut handling

I have one java class which I am exposing as webservice by using webservice annotation.
I am able to pass the input and get the output normally, but incase of any error I need to pass two strings:faultdetails,faultmessage through the fault calss.
So I have created another java class which extends exception class. Also I have used @WebFault in that class. But in that class I am not able pass two strings.
Please help!!!

Your code throws exception when you set value >100 but you are setting 20 thus it would not throw exception.
In the procedure step you can uncheck "Ignore error" flag to let execution failed on throwing any exception from your code. If you check that flag then the execution would not fail rather lease the task in warning state.

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

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

Where is the exception stacktrace - weblogic.webservice.core.handler.Invoke

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!

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

Throw exception in Java mapping and handle this in BPM

Hi,
I'll use a Java mapping in a BPM transform step. Is it possible to throw an exception inside this Java mapping and handle this in a BPM exception handler?
thanks and regards
Verena

Hi Verena,
In a BPM transformation step, I think you can throw exceptions only for system errors.
Let me explain with an example, one of the ways to handle your scenario:
Lets assume your Java Mapping fails then you can trap that exception in your Java mapping and compose an XML message which indicates that an error has occurred.
say for e.g.
<intermediateStructure>
<SatusDocument>
<StatusCode>ERROR</StatusCode>
<ErrCode>123</ErrCode>
<ErrDesc><!populate the thrown exception details></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
if Java mapping is Successful, you can compose the XML message as follows:
<intermediateStructure>
<SatusDocument>
<StatusCode>SUCCESS</StatusCode>
<ErrCode>0</ErrCode>
<ErrDesc></ErrDesc>
</StatusDocument>
<Payload>
<!contains actual XML message with data>
</Payload>
</intermediateStructure>
You can use BPM switch operation to switch to different processing branches say for e.g. "error" branch or "success" branch by examining the value of <StatusCode> tag.
Hope it helps !

Sridhar

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.

Shruti.

Java 1 vs. Java 2 Event Handling

Prelude: This question relates to writing code for event handling.
Java 1 is based on a hierarchy model to handle events, ie. inheritance from superclasses. Java 2 uses delagation event handling method. Java 2 code will not compile if it includes Java 1 code still modeled according to Java 1 event handling.
Question:
Is it generally easier to start completely over in trying to convert Java 1 code into Java 2 code by not retaining any Java 1 code and begin reconceptualizing what is needed for a conversion to Java 2?

From what I understand java2 should support both models, however not both at the same time, you cant mix the modles...
I also think that the older models methods or at least most have been depreciated, meaning that the old model will, if it hasnt allready in the latest release, dissapear.. For that single reason I would recommend updating the event model to the delegation model if you hope to keep it around and running for years to come. You gain a bit by doing this since the newer model is much faster!!!

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
