Web-Service generator : operation arguments

Hello.
I've built a very simple web service to test the JSR 172 API. The server side is built using AXIS. The service is exposed in document/literal style as required by the JSR.
An operation of the service takes as argument a simple structure bean with a string and an integer. The wsdl declares the corresponding complex type, and describes the operation with an argument of this type.
Now, the WTK stub generator generates as expected the stub and the bean classes, but the operation is translated with two arguments instead of the original two members structure. The MIDlet code can obviously call the service passing the two arguments. At runtime, it all works, since both the wsdl and consequent soap body don't make difference about the structure representation.
But what should occur with a more complex structure with many members ? I suppose it should work the same, but not with the preferred interface and usage...
Is it a legal behaviour, according to the JSR or WS-I specifications. Does the WTK only support this 'unwrapped' mode, or is there any way to change it ?
Thanks for your help.

Is this for sure? I am having the same problem, and it seems odd that I am going to have to tell all of the people using my services what the parameters mean instead of them just being able to read the WSDL. Is there any way at all to rename the parameters?

Exception obtained when invoking a web service generated with JDeveloper

Hello,
I tried to create a synchronous BPEL process that invokes synchronously a Java Web Service created with the JDeveloper. The web service is wrapped around a regular Java class. The new created BPEL process is successfully compiled and deployed on the server. But when I try to initiate a test instance of the process in the BPEL console, after I fill the input parameter for then process and push the "Post XML Message" button, I obtain the following error:
Your test request generated the following exception/fault:
BPEL Fault: {http://oracle.com/cde/util/Top300DAO.wsdl}org.apache.wsif.soap.fault{org.apache.wsif.soap.fault.object=java.net.ConnectException: Connection refused: connect}
I looked at flow and it throws the exception when it tries to invokes the web service generated with JDeveloper.
Do you have any hints, ideas? Thanks a lot in advance for your help.
I want to also say that the proxy settings for the BPEL server and designer are filled. I think that they are ok because I succeeded to start an instance of another process that calls synchronously an external Web Service.
Regards,
Marinel

My guess is that this is caused by the WSDL of your service having an invalid service address. Can you please take a look at the WSDL of your service make sure that the location of the address is valid? (we have seen a couple of instances in the past where the generated url did not have the right port information).
Update that WSDL, restart the BPEL server or from the BPEL console clear the WSDL cache and re-initiate your flow.
Best,
Edwin

Problem in using the Web Service generated from BAPI_FLIGHT_GETLIST

Hi all,
I am trying to use the Web Service generated from BAPI_FLIGHT_GETLIST. I have got the wsdl file, and trying to invoke it. But, while I can test the BAPI using the Airline ID AA, I can't test from the Web Service using the same data. It shows the error message - "Airline AA not found". Anyone having solution, please help. This is urgent.
Thanks,

Question about FlyNet Web service generator

I downloaded the 30 day free trial of Xcelsius Engage Server so I could check out the FlyNet product. Can you not just take the compiled asmx and supporting files and drop them to a .Net Web server? When I do this my Web service returns this error in Xcelsius:
Error accessing CAL management service. Please check that the service is running.
If something needs to be configured on the .Net Web server then it will never work here since I will never be able to convince the server support area to install and maintain it.
thanks

Hello Jeremy,
Web Services generated with our Web service Generator have the connection string encrypted and must be used on the machine they were generated on. You cannot just take the .asmx object etc. and place on another server.
The Engage Server version of our product also uses CAL Licensing and checks that the Flynet CAL Licence Manager is running on the machine that the Web Service is generated on, it also requires a valid Engage Server key (the Xcelsius Engage Server key) to run.
Hope that answers your questions. If you need any further information on Flynet Web service Generator then please contact us here at Flynet.
E.Mail support AT Flynetviewer.com or you can e.mail me direct.

Support for xs:date types in web services generated from EJB components

I need to generate a Web Service from an EJB session bean based upon EJB entities generated from the Oracle 11g database that contain DATE type columns.
JDeveloper creates java.sql.Timestamp types in the EJB Session bean and this results in an exception error when I try to generate a web service from this bean via webservice annotations:
java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
java.sql.Timestamp does not have a no-arg default constructor
I expected the web service wizard to generate argument types xs:dateTime or xs:date so this was an unwelcomed surprise.
I tried manually adding a method to the session bean with java.util.date arguments and had no problems with the web service wizard that correctly created xs:dateTime arguments. Is there any particular reason why the EJB wizard does not generate java.util.date arguments or handle java.sql.Timestamp without failing with an exception?
Since I begin with database tables and generate EJB entity classes and then web services with the Jdeveloper wizards it seems to me that there is a problem here in JDeveloper. Would you agree?
There are several possible more or less appealing workarounds, such as doing manually adding methods to the EJB facade with java.util.date arguments and doing the conversion from/to java.sql.timestamp manually. Is this a reasonable approach or does JDeveloper support date/time for Date columns in some other way that I have missed?
Very Grateful for any comments or suggestions.

How to Retrieve Data From Web Service with Optional Arguments

This should be a simple one. I have a web service that
returns a list of books. There are 3 optional arguments that can be
passed to this (ex. book type, author, id) to filter this list. Do
I still need to use the <mx:request> tags if I am not going
to pass any parameters to the web service?
When I look at the services browser in Flex, it says "unable
to get meta data for CFC". However, if I remove the arguments from
the CFC and then call the service again, all my data now appears.
What's the best way to appoach this?
Thanks in advance

I have a similar application. What I have done is create one
argument in my CFC, with a type of "struct". Then, in the Flex
Application, I create an Object (Associative Array), and pass this
to the CFC as that one argument.
Here is the ActionScript:
// Create the variable to be passed to the WebService
[Bindable]
private var object:Object = new Object();
Then in another function, you create the Object, based on
specified values - perhaps from ComboBox selections:
object.bookType = comboBox1.selectedItem["bookType"];
object.author = comboBox2.selectedItem["author"];
object.id = comboBox3.selectedItem["id"];
Then you pass that one argument in your <mx:request>:
<mx:WebService id="getBooks" wsdl"
http://server.com/service.wsdl"
showBusyCursor="true"
fault="alert(event.fault.faultstring)">
<mx:operation name="sBooks">
<mx:request>
<args>{object}</args>
</mx:request>
</mx:operation>
</mx:WebService>
Your CFC might look like this:
<cfcomponent>
<cffunction method="sBooks">
<cfargument name="args" type="struct">
</cffunction>
</cfcomponent>
Then you can worry about validating the values passed to the
CFC in the CFC function. That way, you could send an empty struct
if you wanted, and the CFC would not throw an exception.
Hope that helps.

MDM Web Service Generator - How to Call WS in Java?

Hi there,
I have generated a web service by navigating to http://<server>:<port>/mdm/wsgenerator - The web service is succesfully generated and deployed. I can easily test the web service using the WS Navigator (http://<server>:<port>/wsnavigator).
I am now trying to use NWDS7.2 to create a wrapper web service, and need to call my generated MDM WS using Java code. I have created a CAF project, and imported the MDM web service using the WSDL. I have created an application service and no matter what I try, I cannot get the MDM web service to instantiate.
Is there anyone that has done this before? What method should be used?
All I need to know is how to create an instance of the generated MDM web service - There is no obvious constructor to use. See my code below, but this creates an exception at runtime for "IndexOutOfBoundsException". Note that the web service I generated is called "MdmWfProjectUpdate"
service = new MdmWfProjectUpdateViDefaultService(
                              new java.net.URL(
                                          "http://<server>:<port>/MdmWfProjectUpdate/HTTPBasic?wsdl"),
                              new javax.xml.namespace.QName(
                                          "urn:MdmWfProjectUpdateWsd/HTTPNone", "MdmWfProjectUpdateVi_DefaultService"));
I can call other web services without a problem in my code, so it is quite confusing that I cannot get this to work...
Any help will be appreciated!

Hi david ,
When u imported this webservice,there will be lot of classes generated .In these classes some are executable classes.Like if your webservice contain some operations like update,create,delete.
then for each operation tere will be one executable class generated.
this class must have some function like execute or invoke.You have to call this function in order to get the results.
Just check whether is there any such class generated or not.
Kindly revert back with your results.
Thanks,

Web Service XML Input Arguments Schema Validation

I'm new to web services, but we are currently implementing a number of Web Services that all take as arguments a single parameter which is an XMLBean, which has been generated by a XML Schema.
What I find surprising is that when I submit a SOAP message to the Web Service (through the http Web Service Tester inside eclipse), I can send any valid XML without getting a SOAP fault. Is there a way on the Web Service that I want the XML submitted to be validated against the XML Schema for that parameter?
Bit surprised I have to implement my own input argument validation, and there doesn't appear to be a standard way to do this. I must be missing soemthing surely? Why else would the Schema be in the WSDL?
Cheers
John

Eclipelink plsql web services multiple operation

Hi,
In 11.1.2.2 jdev, I can generate a toplink/eclipse link plsql web services easily for one SQL (dbws).
Can I change the web services to support multiple operations, each for different select sql?
I've tried to changed the wsdl file to have multiple operations
and amend eclipse link-dbws.XML to include multiple query tags.
The web services can be run with multiple operation wsdl but the response of each operation
(using Jdev http analyzer) return only the result of the first operaton.
Can anyone help?
Regards,
Neln
Edited by: Nelson Ng on Nov 10, 2012 8:45 PM

Hi,
I think you are asking for multiple select statements processed by a single TopLink DB Service Provider configuration. As far as I know its exactly one per project and service. However, as this feature is coming from EclipseLink you may want to verify it there

Hi David,
While a random error is still an error it will be difficult for support to find a problem for an error which is not reproducible. It is always a faster resolution if you can determine how to provoke the error and provide those details. If we can reproduce an error on internal systems then we can fix the problem quickly and without having to access your system.

PL/SQL Web Service element, operation, part names etc all in lowecase

I have generated web services from pl/sql packages on a 11.2.0.1.0 database using JDev 11.1.1.5.0. In the generated wsdl all the names are in lowercase. Is there anyway of getting these names to match the case the objects are stored in the database?
Eg. CREATE OR REPLACE TYPE sampleEntity AS OBJECT (entityNumber INTEGER
,entityType VARCHAR2(1)
,displayName VARCHAR2(400))
But in the wsdl they are all lowercase:-
Eg.
<xsd:complexType name="sampleentity">
<xsd:sequence>
<xsd:element name="entitynumber" type="int" nillable="true"/>
<xsd:element name="entitytype" type="string" nillable="true"/>
<xsd:element name="displayname" type="string" nillable="true"/>
Thanks.

Ok, this sounds like a known bug ( Bug 5908689 ) in 10.1.3.1, but this was specific to non-Windows platforms. Are you on Linux/Solaris or any other platform? It might or might not be the same problem you are hitting but it does seem quite close (can't say for sure without a close investigation, I am afraid!)
In any case, this bug is fixed in the 10.1.3.4 patchset (besides quite a few other fixes and enhancements) - so would recommend you to first apply the 10.1.3.4 patchset and retest. The patchset is available on My Oracle Support (formerly Metalink) under Patch 7272722. Or you could go a step ahead, and apply the 10.1.3.5 patchset (Patch 8626084) instead which is the latest patchset for OracleAS 10.1.3.x.

Hi there,
10.1.3 is not production ready yet, and you will find this warning on the oracle page http://www.oracle.com/technology/tech/java/oc4j/1013/index.html

Does this mean that it's not possible to deploy a Doc/Lit webservice to production using JDeveloper? Is there any other way of getting it to work with 10.1.2?

Urgent - Error calling web service generated from plsql package

Hi,
I am using Jdeveloper 10.1.3 production release.
I am trying to publish a plsql packaged procedure as a web service.
My first question is -
When I am publishing the plsql API as a WS, should I choose the style Document/Wrapped or RPC Literal? Document Wrapped is the default in the wizard.
My second question - Depending on whether I choose Document/Wrapped or RPC Literal style, I get 2 different errors when I try to run the client java file (generated by Jdeveloper) that calls the web service. The client java compiles successfully but when I run I get these messages:
Document/Wrapped error -

Now all the classes are generated by JDeveloper automatically from the plsql API. So I am not sure why the errors occur and how to fix these.
Also, these errors are occurring on plsql APIs that have input or output parameters of plsql record type or pslql table of record type. These errors don't occur if the api is simple with scalar input or output parameters only.
I would appreciate any help on how to resolve these errors.
Thanks,

Hi,
I'm wondering if the problem is actually that the client is failing to connect to the server correctly. Can I suggest that you switch on the HTTP Analyzer and see what comes back there.
Is it possible it is a proxy problem? If you are working locally then I first suggest that you ensure that the Web Browser Proxy is off (see Tools -> Preferences -> Web Browser Proxy) - and that there are no exceptions listed (either with the proxy on or off) before you start the HTTP Analyzer.
As to Doc/Wrapped or RPC. see this blog entry for a little more explanation:

Web services generated from proxy

Hi,
We have few webservices generated through SE80 from a proxy interface, so that an external web service can directly reach them.
I mean to say, that the wsdl we generated is provided to the external web service.
My question is that when the message direclty flows to the R/3 system via the proxy, do we have any means to monitor them??
How do we do the error handling in those cases?
Thanks,
John
