Web Service and Complex Types

Hi, I am creating a web service based on a java method that returns a Java bean. This is translated into a complex type in the wsdl containing the beans member variables. During this generation JDeveloper names the complex type as package structure + javabean class name. Is there anyway to change this to just javabean class name ? Secondly is there any way to change the case of the complex type element names (so the initial character is upper case)? I realise that in an ideal world what JDev generates would be OK but I have to meet a spec produced by someone else.
Thanks for any help.

Does anyone have any experience with this ?

Apex, Web Services, and complex data types?

Hi all,
I was wondering if somebody could explain to me what sort of support apex has for using web services with complex data types, and how data returned like this could be interpreted and stored in the database.
Any help would be aprreciated.
Thankyou in advance

Hi can anyone help me with this?

Pl Help......Web services with complex types

Hi,
I have deployed a web service on OC4J (9.02) having a complex type input and a complex type return. The web service is implemented as a stateless session bean and
the relevant web.xml for the deployment is:
<servlet>
<servlet-name>ZipLookupManager</servlet-name>
<servlet-class>oracle.j2ee.ws.SessionBeanWebService</servlet-class>

The web service deploys correct. I have all the relevant jars in the %J2EE_HOME%\lib folder. However, when I call the web service from a standalone client I get the following error:

Hi all,
I haven't heard back from anyone. Is this forum alive still? I have entered a TAR on metalink on this issue but they say that apparently this was a defect under 9.02 and has been fixed under 9.04.
Please help.
Many thanks in advance.

Accessing a web service with complex types

Hi I have been struggling with this web service for a while
now....
I am trying to send input parameters that are composed by :
applicant name( name, surname, .....) and applicant input address(
hse no, street, postcode...) Applicant dob(dob)....I am using
<cfscript> tag to pass these parameters...Now my problem is
do i need to put each complex type inside its own <cfscript>
tag???
ie:
stName = structNew();
stName.Title = "#Mr#";
stName.forename = "Man";
stName.othernames = " NA";
stName.Applicant = "Yellow";
stName.suffix="";
stName.dob = createDate(1972,06,05);
and do this for applicant address? or could i enclose this in
under the same cfscript tag??
Any help would be appreciated...thanks

Web services and date type

Hi,
I have a web service method which returns Date type value.
That method is used by a j2me client.
But j2me web services does not support Date type.
Are there any possible ways that I can get around this limitation?
Thanks,
Chamal.

Hi Rohit, the input of ws is a structure like this:
date
installationNr
sid
userID
.Workload
..aDataVol
..aDbTime
..bsteps
..client
..cputime
..dsteps
..QuequeTime
..respTime
..sDataVol
..sDbTime
..steps
..userAccnt
..usteps
It returns nothing...
When I call this ws after I have used all generated classes in model error is:
Array Property [Item] in class [none] must not have NULL elements. This is restricted by schema description.
I invoke this ws with XmlSpy and I see that there is a tag <item> after tag workload, and item contains the next tags. So there's one level that generated classes don't see.
any ideas?
thanks

EJB3 Creating Web Services with Complex Return Types

Hi
Not sure if this is the right place, but hoping someone can help!
I have an entity bean that has a collection (list<Address>) of sub-entities. I have then created a session bean to retrieve the Business and populate it's children.
I then expose this as a web service and although it works and I get appropriate XML out, the WSDL of the deployed service is not as I would like.
For example:
The return type is
<complextype name="Business">
<sequence>
<element name="id" type="int"/>
<element name="addresses" type="ns1:list"/>
</sequence>
</complextype>
<complextype name="Address">
<sequence>
<element name="id" type="int"/>
<element name="addresses1" type="string"/>
<element name="addresses2" type="string"/>
<element name="addresses3" type="string"/>
</sequence>
</complextype>
ns1:list is included as a separate schema as a complex extension of the base "collection"
So, even though the Address type is there it is not referenced from Business.
So, when I'm calling the Web Service from BPEL or ESB, I have not got the ability to map adequately back from the response.
I have tried a whole bunch of ways of getting this to work, but so far to no avail...
Has anyone seen this before, or can I somehow override the mapping from the Entity to the WSDL?
Any help would be most appreciated.
Thanks
Chris

Thanks. We are using a Java Proxy to consume the web service as we need to use JAX-WS handlers. We created data control from the service stub that was created by the proxy. Our issue is with the response XML which comes as a complex type. Also, the data control is understanding the complex type and is creating the structure right. The problem is when we drag that control on a JSF page. No data is displayed. We think that we are not traversing the complex object properly which is creating the issue.
I understand that you answer related to the input is applicable to output as well. We can change the structure by flattening it but we thought that in 11G there is some new features where we can use the complex types out of the box without any change. Is that true? Also, any luck in finding the documents (broken links) on your blog page?

Consuming Java Web Service with complex return types

Hi,
I'm consuming a Java Web Service and the return I get in
ColdFusion is a typed Java Object (with custom Java classes like
com.company.project.JavaClass ...)
Within this object I don't get direct accessible properties
as when I'm consuming ColdFusion Web Services, instead I get a
getPROPERTYNAME and setPROPERTYNAME method for each property.
How can I handle this? I don't want to call this methods for
each property (and there are nested objects with arrays of custom
classes below, which would really make this complicated).
What's the best way to cope up with this?
Thanks a lot,
Fritz

The web service is actually the function, not the cfc and you
didn't show a function.
My own opinion is that since webservices by definition should
be available to any calling app (cold fusion, .net, flash, etc),
whatever gets returned from the method should be as universally
recognizable as possible. This generally means text, numbers,
boolean, or xml.

HotFix 2 breaks web service results of type xsd:anyType

I have a client that accesses a number of web services that
return results as type xsd:anyType (the results are complex XML
hierarchies that change according to db values). Before HotFix 2,
in in my ResultEvent.RESULT event handler, I could get access to
the result via the ResultEvent.result property. But since HotFix 2,
the ResultEvent.result property is always null for web services
results of type xsd:anyType (for other result types,
ResultEvent.result is correct).
This is a major nuisance!! I assume this is a bug, so can
anyone suggest any workarounds while I wait for Adobe to fix it? I
can access the result as a string via the EventResult.message.body
member. And from there, I can parse the XML, and perform an
XML-to-ValueObject conversion... does that sound reasonable? Does
anyone have an examples of XML-to-ValueObject conversion code to
help get me started?
Any hints or tips would be most welcome ;)
Thanks!

How to use Adaptive WebService Model with CAF WebService and Complex Type

Hi All,
I am trying to use the Adaptive Web Service Model and call a WebService generated by the CAF. The return type of the WebService is a Complex Type.. I receive an exception when trying to instantiate the Model Node.
Does anybody know how to use the Adpative Web Service Model with CAF WebServices and Complex Types as return type?
Help is appreciated..
Thanks, Johannes

Thanks Mukesh.
It is not possible to apply the Service Controller Template on Enterprise Java Bean Models as described in the Document. When I try to aply the template on the EJB Model, NWDS says: Only Webservice Models and RFC Models are supported...???
I did not find any information about how to return complex types in AWS.. in this document???
Is there such information available? Has anybody ever done that? There must be a way to do that.. Is is the standard approach, isn't it...? Please help me out there.. I need to get this running..
Thanks, Johannes

Help needs to build this web service and do this exercise

**i'm a newbie to java. can anybody give me a help here.**
Exercises :
1) Develop customer profile web service as below: which having two methods saveCustomer and retrieveCustomer
Customer infomation data structure as follows
CustomerID :string
Name :string
phoneNumber : int
Address : Object which contain(home number(int), street(string), town(string))- Complex type object
Age: int
LastBalance: double
Ex1:
you send the SOAP request (in your web service call) with customer id or phone number the web service should return customer information and display as system out.
Note Just hard code customer dummy data inside web service method call getCustomerData which return the customer object.
Ex2
Compose customer object (java object) in client side and send via web service using web service save method to write to a data to text file in server side (in your case same machine , but it create by customer profile web service not the web service client)
Objective of this exercise is to understand web service / soap complex and simple variable types and how to exchange those with SOAP request and response.
Exercise 3:
send some wrong customer id or phone number as input to webservice method "retrieveCustomer" and generate error and send it via SOAP fault to client and display it

ok thanks any way. i hav done most of the exercise. don't know wthr the appraoch is correct or incorrect. i'll post what i have done up to now.
Customer.java FILE
package com.server;
public class Customer {
     public String customerID;
     public String customerName;
     public int phoneNumber;
     public Adress[] address;
        public int age;
     public double balance;
Address.java FILE
package com.server;
public class Address {
     public int homeNumber;
     public String street;
     public String town;
CustomerService.java FILE
package com.server;
public class CustomerService{
     public Customer getCustomerData(int CustomerID){
          Address address1 = new Address();
          address1.homeNumber = 23;
          address1.street = "silva lane";
          address1.town = "kandy";
          Address address2 = new Address();
          address2.homeNumber = 45;
          address2.street = "gampola road";
          address2.town = "peradeniya";
          Address [1] address = new Address[] { address1, address2 };
          Customer customer = new Customer();
          customer.customerID = "abc";
          customer.customerName = "mahesh";
          customer.customerphoneNumber = 345565767;
          customer.address = address;
          customer.age = 25;
          customer.balance = 25000.00;
          return customer;
}is thr anything i hav missed. please advice.

Creating PL/SQL web services from object types

Hello
Jdeveloper, pl/sql web-services working successfully with object types.If we want to send the web-services to the client, do we need to send the entire folder that is created in the web-services folder of the external oc4j..?
Creating the client process:
we are using the wsdl file that is generated in the web-services and adding to the partner link to Invoke the operations of web-services. Is there any other way to invoke the webservices?Could any one please suggest me?
Thanking you

Hello
Accessing the pl/sql webservices from the application server:
I have created pl/sql webservice using the nested tables.

The above web-services working and I am able to insert into the database tables.
Same when I want to access through the application server, I have changed the wsdl file soap address as
<soap:address location="http://10.91.20.7:8888/PL_SQL_WS-Nest_Obj_Webservice-context-root/ObjWebserviceSoapHttpPort"/>
When I access this url, I am able to give the input data
http://10.91.20.7:8888/PL_SQL_WS-Nest_Obj_Webservice-context-root/ObjWebserviceSoapHttpPort
but the out from the web-service is:

How can I get this to work ? (without using Apache Axis or other tools :-)
Is it supposed to work ?

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

Java app with web service and servlets

Hi. I intend to make a java application which exposes some methods as a web service and as jsp/servlets. It's core functionality is not really web centric, but its more a java app with a web tier. I am not sure about how the architecture of such a system would look like using the java platform. I currently see three options:
1. Run everything in a servlet container like tomcat. I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web services. However, it would be really easy just to put everything into tomcat and use ServletContext to maintain some global objects.
2. Use a Java EE to seperate application/business logic and data access into session beans and entity beans. I hesitate to this because it seem a bit overkill because the system isn't very big or complex right now. It also means that I would have to learn to use EJB's instead of just using some POJOs.
3. Run the web tier in a servlet container and the main app in a separate JVM, and then connect the tier by sending serialized objects over TCP sockets. I don't like writing network code but at least there is some separation of the tiers.
What would you do? Maybe I have overlooked a much better solution to the problem?
Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) instead of the something quick and dirty that is hard to defend.

jschell wrote:

Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) That pretty much makes it impossible then.
1. A "Right" solution is generally only proven by time.
2. It requires a great deal of knowledge about the business domain.Yeah, you are right. Let be try to rephrase it. What solution (pattern) would be considered the most common or appropriate when you have a Java App and want to expose a few methods as a website and web service?
I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web servicesHuh? Do you already have an exposed web service? If you already have a server which other clients communicate then where does this functionality that you don't want to be tomcat running now? Or where do you think that you want to run it? And if you are or do run it somewhere else then tomcat could access it the same way any other client accesses that server.Sorry, that sentence was written badly. I don't have anything right now. What I meant to write was that I will have a lot of application scope data, objects that are kept in memory as long as the server is running, shared by multiple servlet instances.
