Returning XML to client from web service

Hi,
I am new to developing web services using JAX_RPC. I am trying to return a xml document to the client from the web service.
My Server implementation is as follows:
Interface:
public interface OntoIF extends Remote
public DataHandler ontoCompare (String targetUrl,String sourceUrl ) throws RemoteException;
Implementaion:
public class OntoImpl implements OntoIF
public DataHandler ontoCompare (String targetUrl,String sourceUrl ) throws RemoteException
DataHandler dataHandler = new DataHandler( new StreamSource( new File ("status.xml")), "text/xml");
return dataHandler;
Client Implementation:
Stub stb = (Stub) (new OntoService_Impl().getOntoIFPort());
stb._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY,
"http://localhost:8080/onto-service/onto");
OntoIF onto = (OntoIF) stb;
DataHandler retDHandler = onto.ontoCompare(targetOntoUrl, sourceOntoUrl);
When I compile and run my client, it throws the following error -
java.rmi.ServerException: JAXRPCSERVLET28: Missing port information
at com.sun.xml.rpc.client.StreamingSender._raiseFault(StreamingSender.ja
va:497)
at com.sun.xml.rpc.client.StreamingSender._send(StreamingSender.java:294
at sstub.OntoIF_Stub.echoDataHandler(OntoIF_Stub.java:122)
at sstub.OntoClient.main(OntoClient.java:63)
Can you please let me know what I am doing wrong? I have no problems in sending a DataHandler but receiving the DataHandler from the web service throws errors.
Thanks!

Hi I'm having the same problem. I try to set up a Web Service using JAX_RPC. My WS should invoke a native Method implemented in C++. Did you got a solution for this issue? My Error Message is as follows:

Error returning large String arrays from web service

Hi,
I currently have an EJB that returns a String[] array that I have implemented as
a Web Service. When I execute a Java client (JSP) from Weblogic, I don't have a problem
as long as the returned array is relatively small, but when the array starts to get
a little larger (say 20 elements, about 30 chars each), I consistently get:
SAXException: java.lang.IllegalArgumentException:array element type mismatch.
Strangely enough, when my web service client is a .asp page running under MS IIS
(using the MS SOAP Toolkit), it works fine. I have returned as many as 15000 - 20000
array elements in one call. And since I am calling the same Weblogic EJB with the
MS client, I know it's a problem with the Java client, not the EJB.
Anybody know of a bug or had this experience before? Or know what I might be doing
wrong? FYI, I am using Weblogic 6.1 SP2.
Thanks,
Steve

Hi Steve,
Sure we're interested...I'll pass this along to the XML folks.
Thanks for the feedback,
Bruce

In case anyone is interested, I solved my problem. I was mis-diagnosing the problem
- thinking it was a size issue when it actually was a data issue. On the calls where
I was returning a large array, some of the array members were null. When I made them
enpty strings "", it worked. Apparently the default SAX parser BEA uses doesn't like
the nulls, whereas the MS parser doesn't care.

How to return List or Array from Web Service without using ADF?

All,
I would like to know how to do this before I use ADF. Sounds like a simple thing to do - common even - but I haven't found a solution in existing postings. My attempts have failed though I'm not sure exactly why.
I have created a declarative WS that takes a single parameter and tries to return a List<Employees> resultset. My Sample Java Client works just fine. When I change the result type from List to String[], for example, it also works fine.
What am I doing wrong??
Thanks

Gi,
not sure what you are doing there, but you can build the J2EE WebService from your working POJO, and create a Web Service proxy class from the WSDL description (of the deployed or local WSDL file). Then, using the proxy class, you can access the output of the WebService.

Return arrary of objects from web service

Hello ALL,
This problem has stumped me for several days.
I have a web service and a jsp client. the jsp client call the web service. the web service function return an array of object of DataBaseRecord type. I use XFire + MyEclipse + Tomcat to develop this project in a Linux box.
the web service WelcomeYou is defined as follows
{noformat}public List<DataBaseRecord> WelcomeYou(String ExampleDoc)
   List<DataBaseRecord> RetrievalResult = new ArrayList<DataBaseRecord>();
// Search relevant documents according to 'ExampleDoc' from a database
// The search result will be put into a RecordSet object 'rs'
   while(rs.next())
              DataBaseRecord NewRecord = new DataBaseRecord ();
              NewRecord.RetrievedDocID = rs.getString("RetrievalDocID");
              NewRecord.SimiScore = Float.valueof(rs.getString("SimiScore"));
              RetrievalResult.add(NewRecord );
// I use the following for loop to see the content of RetrievalResult. I can see that the content is just what I expect. Additionally, the size of RetrievalResult is correct too.
for(DataBaseRecord   databaserecord : RetrievalResult)
     System.out.println(databaserecord.RetrievedDocID + databaserecord.SimiScore);
return RetrievalResult;{noformat}in a jsp file, the web service WelcomeYou is called
{noformat}List<DataBaseRecord> Result = new List<DataBaseRecord>();
Result = srvc.WelcomeYou("some text ");
// I use the following for loop to see the contentof Result, but each element of Result is empty. Moreover, the strange thing is that the size of Result is right.
for(DataBaseRecord   databaserecord : Result)
     System.out.println(databaserecord.RetrievedDocID + databaserecord.SimiScore);
{noformat}the class DataBaseRecord is defined as follows
{noformat}public class DataBaseRecord{
    public String RetrievedDocID;
    public float SimiScore;
{noformat}At the very end of the service function body(just before ' return RetrievalResult;'), i check the content of RetrievalResult using a for loop, it is correct.
At the jsp file, immediately after the statement
{noformat}   Result = srvc.WelcomeYou("some text ");
{noformat}
{code}
, i check the content of Result using a for loop, it is incorrect except for the size of Result .
I wonder where I am wrong in the above code.

Facing problem while going to catch return result from web-services.

Hi everybody,
I am new to BPEL. I am facing problem while going to catch the attributes of resultsets returning from web-services(QAS). As far as my knowledge, two types of results it should return - XML entities and another is attributes which is coming as the part of XML entitites. I am able to catch the XML entities, but can't catch the attributes under it. Even, I am not able to see whether web-services returning something within that field.
When, I tried to catch the attribute and store to a temporary varilable using the following code:
*<assign name="AssignQASDoGetAddress1">*
*<copy>*
*<from variable="InvokeQAS_DoSearch_OutputVariable"*
part="body"
query="/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded"/>
*<to variable="temp"/>*
*</copy>*
*</assign>*
but, I am facing the following selectionFailure errors after running it:
*"{http://schemasxmlsoap.org/ws/2003/03/business-process/}selectionFailure" has been thrown.*
-<selectionFailure xmlns="http://schemasxmlsoap.org/ws/2003/03/business-process/">
-<part name="summary">
*<summary>*
empty variable/expression result.
xpath variable/expression expression "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')" is empty at line 269, when attempting reading/copying it.
Please make sure the variable/expression result "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')"is not empty.
*</summary>*
*</part>*
*</selectionFailure>*
Getting this error it seems to me that web-service is returning nothing, but, it returns something as it has been catched using a method called isPostcodeRecoded() Java Code in Oracle ADF. This method has been used as it should return boolean whereas for catching the xml entities using java code we used the method like getPostcode(), getMoniker().
For your information, we are using Jdeveloper as the development tool for building the BPEL process.
Am I doing any syntax error. Please consider it as urgent and provide me asolution.
Thanks in advance.
Chandrachur.

Thanks Dave and Marc, for your suggestions. Actually what I found is QAS web-service is returning nothing as attributes when the attributes are set to the default value. For example, following is the part of the wsdl of the result which QAS webservice returns.
<xs:element name="QASearchResult">
- <xs:complexType>

<xs:attribute name="MoreOtherMatches" type="xs:boolean" default="false" />
<xs:attribute name="OverThreshold" type="xs:boolean" default="false" />
<xs:attribute name="Timeout" type="xs:boolean" default="false" />
</xs:complexType>
<xs:complexType name="PicklistEntryType">

<xs:element name="Moniker" type="xs:string" />
<xs:element name="PartialAddress" type="xs:string" />
<xs:element name="Picklist" type="xs:string" />
<xs:element name="Postcode" type="xs:string" />
<xs:element name="Score" type="xs:nonNegativeInteger" />
</xs:sequence>
<xs:attribute name="FullAddress" type="xs:boolean" default="false" />
<xs:attribute name="Multiples" type="xs:boolean" default="false" />
<xs:attribute name="CanStep" type="xs:boolean" default="false" />

<xs:attribute name="CrossBorderMatch" type="xs:boolean" default="false" />
<xs:attribute name="DummyPOBox" type="xs:boolean" default="false" />
<xs:attribute name="Name" type="xs:boolean" default="false" />
<xs:attribute name="Information" type="xs:boolean" default="false" />
<xs:attribute name="WarnInformation" type="xs:boolean" default="false" />
<xs:attribute name="IncompleteAddr" type="xs:boolean" default="false" />
<xs:attribute name="UnresolvableRange" type="xs:boolean" default="false" />
<xs:attribute name="PhantomPrimaryPoint" type="xs:boolean" default="false" />
</xs:complexType>
here the attributes like FullAddress, PostcodeRecodedare , etc. are not being return by the web-service when it is getting the default value false. But, if it gets true then , it is being displayed at the BPEL console.
Do you have any idea how can I catch the attributes and its value even when it gets the default value which is already set. Previously, it was returning(it was not being displayed at the console).
Thanks once again for your valuable suggestions...!!!

these are the steps i intend to follow to accomlish the requirement.
1) middleware tool has to initiate the call to kenexa web services to receive the xml file when it is available.
2) On SAP we need to create a ABAP Proxy service provider to middleware where this file can be received.
Can any one guide me how i can create a proxy to retrieve the xml file from web services by initiating call through other middlewre (its not PI).
Any help would be really great, i am not a ABAP developer, so please help me with this. Thanks.

Thank for reply.

Presence data from web service

Hello,
i like to get presence data from the presenceconsumer web service. But everytime a call getUserPresence i get a PolicyException (POL0002): 'Privacy verification failed for address %1, request is refused'.
I use a web service proxy generated from the wsdl of the presenceconsumer web service. Authentication is made against the appregationproxy by setting username and password. Both users (the one i use for authentication and the one whose presence data i want to get) are registered in the timesten database.
The user whose presence data should be accessed is logged in the OracleCommunicator and has the other user on the allowed list for presence data.
All other operations of the presence web services work without any problem, so why not getUserPresence?
Thanks for help

Hi,
I have found the problem and fixed it :)
If you see my code, I was checking for the pending subscriptions after publish() method. When I tried this check before publish() method, I got the expected results (All the pending subscriptions).
Also, I got an error (ServiceException) while dynamically retrieving the subscribed attributes for some reason. I have found an alternative solution, by manually allowing only the PresenceAttributeType.Activity (instead of all getSubscribedAttributes()).
Note: This code was working fine in my local machine because, I have already setup-ed the users (Buddy list) through Oracle communicator in my machine. I was not able to install OC in the VM for some reason though OS is same in both my machine and the VM (OS: Windows 2000 SP4).
thanks & regards,
S.Vasanth Kumar.

Dates coming from web service

Hi,
I'm currently trying to consume in VC a CAF Application Service exposed as a Web Service. I'm able to retrieve what I want but I have a problem with dates format.
The web service returns dates in the following format: YYYY-MM-DDTHH:NN:SS
When I test my data service in VC it works fine. When I run my iview, VC swap the month and the day and compute the new date...
It's not just a problem of formatting with DVAL and DSTR because the date is already computed.
Example:
Date returned from web service: 2007-09-21T00:00:01
Date returned from test data service in VC: 21.09.2007
Date returned at runtime: 09.09.2008
VC understand 21.09.2007 not like DD.MM.YYYY but like MM.DD.YYYY so 21.09.2007 becomes 09.09.2008
I also tried to check on the server Regional and Language option but it doesn't come from there.
Have you ever faced this problem?
Thx

Hi,
It is a Web Service generated by NWDS (to expose my CAF Application Service)and deployed on the server.
The url si like http://<hostname>:<port>/mywebservice/Config1?wsdl
The Web Service runs correctly.
When I call a method of my web service to retrieve a list of objects (CAF Entity Services) and their attributes, it returns attributes of type String and Dates of type 'java.util.GregorianCalendar'.
It seems that VC doesn't correctly understand this type of Date at runtime
Regards,
Thomas
