Data Service Auto-Detect Return Type Error

Hello,
I am not sure if I am posting in the correct area, as this is my first post in a long time. I have an error when trying to Auto-Detect Return Type for my Web Service Data Service. The error is 'Data type "Table_type" cannot be merged with the existing one in package "valueObjects" because the property "ContentID" does not match in case.' I have configured other return types the exact same way and have tried looking in the documentation for this error as well as searching on the internet. Any help would be welcomed, Thank You.

Nevermind, I figured it out. If anyone else has this similar error, it means you have another variable with the exact same name only capitilized in the same return type.

Flex services with multiple return types

Hello,
We are creating a webapplication with flex and php.
Everything is working very good, until we got to the library part of the application.
Every service so far had only 1 return type (eg: User, Group, ...)
Now for the library we want to return a ArrayCollection of different types of objects. To be more specific the LibraryService should return a ArrayCollection containing Folder and File objects.
But how to configure this in Flex (Flash Builder 4 (standard))?
So far it converts every object to the type Object, i would really like it to be Folder or File
The only solution we can think of right now is to create a new object Library that will contain 2 ArrayCollections, one of type Folder and one of type File. This could work ofcourse, but I wonder if there is a better solution for this OR that i can configure multiple return types for a service.
Any ideas/advice is greatly appreciated.

Normally if you are using Blazeds(Java stuff, i'm sure there should be something similar for php), you can map java objects to that of the AS objects, when you get the data back you are actually seeing the object which is a Folder or a File object rather than just a Object.

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?

Generics (return type error)

Hi to everyone, I'm new around there!
I have 2 questions to ask:
I tryed to implement a generic tree inside of wich I created a "search" method.
This method needs the method "compareTo" of the class "Comparable" to compare nodes, so the tree class requires a bound and the header is the following:
public class BTNodeGen <T extends Comparable>
The problem is that in this whay the search method returns a Comparable instead of a generic type. The method is the following:
public <T extends Comparable> T search(T el)
          if (el.compareTo(key)==0)
               return(el);
          else if((el.compareTo(key)<0) && (left != null))
               return ((T)left.search(el));
          else if(right != null)
               return ((T)right.search(el));
          else
               return null;
     }This method works and returns a T only because I added some downcast to T before the return, otherwise it gives a compile error because it is returned a Comparable where is expected a T.
How can I do to avoid downcasts (that aren't so much correct for a OO language...)?
Can you help me?
A last question: what changes between the following header of the method search:
- public <T extends Comparable> T search(T el)
- public T search(T el)
and between the following class header
- public class BTNodeGen<T extends Comparable>
- public class BTNodeGen<T extends Comparable<T>>
Thanks for all

All two methods (Malvolio and carr_onstott) works fine, thanks a lot!
I had to modify the header of carr_onstott's method with:
public <T extends Comparable<T>> T search(T node, T root)
because it gives 2 errors, one of wich is that:
D:\UNI\Progetti\MP\1\BTNodeGen.java:191: > expected
    public <T extends Node, Comparable<T>> T search(T node, T root)
                                      ^Why it gives that error?
Thanks to Malvolio I understood what was my fault: in the sons declaration I left "<T>".
In fact with
public BTNodeGen<T> left, right;
it gives no type error and I don't need downcasts.
I always tried to pass in the key value as parameter, but without the correct son's declaration it didn't work.
When I finish to test deeply the entire structure I'll post the results and all the structure's code.
Thank you very much, I was lost without you!

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.

Publish ColdFusion Web Service with Complex Return Type

Hi,
I am working on a project to publish couple ColdFusion
webservices. The cosumer of those webservices is a Java
application.
One of my webservice need return an object. Here are demo
codes:
The returned ojbect is AddressRespond
AddressRespond.cfc:
<cfcomponent>
<cfproperty name="addresses" type="Address[]" />
<cfproperty name="myLearnException" type="MyException"
/>
</cfcomponent>
Address.cfc:
<cfcomponent>
<cfproperty name="city" type="string" />
<cfproperty name="state" type="string" />
</cfcomponent>
MyException.cfc:
<cfcomponent>
<cfproperty name="code" type="string" />
<cfproperty name="reason" type="string" />
</cfcomponent>
If the webservice "cosumer" is a ColdFusion application,
there is no any problems. But the Java application doesn't
understand the type of addresses in the WSDL file which is
gernerated by ColdFusion:
<complexType name="Address">
<sequence>
<element name="city" nillable="true"
type="xsd:string"/>
<element name="state" nillable="true"
type="xsd:string"/>
</sequence>
</complexType>
<complexType name="MyException">
<sequence>
<element name="code" nillable="true"
type="xsd:string"/>
<element name="reason" nillable="true"
type="xsd:string"/>
</sequence>
</complexType>
<complexType name="AddressRespond">
<sequence>
<element name="addresses" nillable="true"
type="tns1:ArrayOf_xsd_anyType"/>
<element name="MyException" nillable="true"
type="impl:MyException"/>
</sequence>
</complexType>
Could anybody give me any idea on how to resolve this
problem?
Thanks!

JCO Return Type error for BAPI_GOODSMVT_CREATE

I'm working against a 4.6c instance using the BAPI_GOODSMVT_CREATE to do a 261 movement type. When running through Xacute, I am getting the attached Return message:
<RETURN>
<item>
<TYPE>E</TYPE>

<MESSAGE_V4 />
<PARAMETER>GOODSMVT_ITEM</PARAMETER>

<FIELD />
<SYSTEM>QAS150</SYSTEM>
</item>
</RETURN>
I know for sure that this item is maintained in this plant as I can perform the 261 through SAP GUI and through ABAP. Has anyone else run into this problem? There is an OSS note (570790) for this BAPI, but I think this patch has already been applied.

Hi Rick - thanks for your quick response.
I'm fairly confident I have the right config as I can do other BAPIs without any problems. I did check the material number as well; it is zero padded correctly - again I believe.
I could be wrong. I have someone looking into the patch in the OSS note. Perhaps that is the answer.

Data service (DB adapter) returns XML with missing collection's content

Hi.
JDeveloper use aliase names for tables by default so aliases t0, t1, t3 are used for tables basketinvoice, basketitem, documents.
I think there is some connection to table. Collection of basketinvoicepayments table is missing when 3 tables select and 2 tables select too.
Table basketinvoicepayments is child table and it's element is missing even when relationship is 1:M or 1:1 (Foreign Key on Child table).

Data Services Designer - Function returns value, but doesnt always populate

Within my Query Transform I call a function that I pass a old Vendor code to a sql statement and it does a few lookups and cross references it returns a new value. My issue is sometime it doesnt put the value in the field. I know it has returned a value as I had the funtion print it out for me, so I can see the value that was passed and the returning value, but when I look in my table there is no value.
I have added the function call for you to see it is very simple takes one parameter, I have also added the print out from my function, does anyone have any ideas??

Data Service Wizard - How can I reconfigure return type field as XML (E4X) value

The HTTP Data Service wizard - "Reconfigure Return Type" - does not allow XML (E4X) to be selected as a data type for a field. For example , If my example XML payload looks like this (see below), I would like to set the datatype for "settings" field to be XML (E4X) and have the service decode the "string" value into an XML (E4X) value.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ListOfUsers version="1.0.0">
    <User>
        <id>3</id>
        <subType>INTERNAL</subType>
        <authName>internal</authName>
        <name>Internal User</name>
        <settings><?xml version="1.0" encoding="utf-8" ?><Settings><Profile><Region>emea</Region><Language>en.g b</Language></Profile></Settings></settings>
    </User>
</ListOfUsers>

I find a (reasonably) elegant workaround which is to add a transient property in the "public" sub class of the value type - see below - I havent tested it much so not sure if it will work adequateky in all circumstances
package services.listeningpost
public class User_type extends _Super_User_type
public function get xmlSettings():XML
return new XML(settings);
public function set xmlSettings(object:XML):void
settings = object.toXMLString();

Zend AMF Data Service Return Problem

Hi Folks,
I am working with FB4 and Zend AMF/PHP and MySQL. I began integrating the PHP stuff using the great article by Mihai Corlan called 'Working in Flash Builder 4 with Flex and PHP. I followed all the steps exactly, aside from creating my own app-specific PHP classes and functions, etc... I 'hooked up' the Zend stuff just like the article, created a text datagrid, just like the article, and viola!, it worked. I then tweaked it a bit and interwove it into my 'real' component. So far, so good.
Then I created a second PHP class with a different 'get data' type of function. It queries a different table in MySQL, but is essentially the 'same' as the query/function in the initial PHP class.
In FB, in the Data Services window, I choose the 'Connect to Data/Services' function, just like the first time. I then find/select my PHP class file and FB 'interrogates it' enough to show me the function that exists in the class. I 'finish' the operation and it adds a new 'service' to the list of services in that window. Again, so far, so good.
The problem comes when I try to 'test' the service or 'configure return types' (which basically requires a 'test' operation anyway). I can enter the 'input' params just fine, but when I try to execute the call, I get the following error:
InvocationTargetException:There was an error while invoking the operation. Check your operation inputs or server code and try invoking the operation again.
Reason: An error occured while reading response sent by server. Try encoding the response suitably before sending it. e.g. If a database column contains UTF-8 characters then use utf8_encode() to encode its value before returning it from the operation.
I don't know where to go after this. Again - the 2nd PHP class is essentially identical to the 1st. The function in it is essentially identical, differing only by the input params, the name of the function and the actual SQL it sends to MySQL. There is no special text, no special characters, no image stuff, nothing. I do not 'encode' the results of the function in the first class - in fact the code in the second class is practically identical to the first. I do not know what the error is talking about. My guess is that it's more of a generic message.
I can debug the PHP code just fine from within a seperate instance of Eclipse. The function runs/returns just fine - an array of PHP-defined objects (simple strings).
Any insights or advice would be welcomed.   Thank you,
-David Baron

Thank Jorge, but that was not the issue, though, it may be related.
I checked the mySQL my.ini file, and there was already an entry for:
[mysql]
default-character-set=utf8
I added the 'default-collation=utf8_unicode_ci', like you suggested, but that didn't do anything.
I checked the Apache httpd.conf file, and added the following line 'under' the "DefaultType text/plain" line:
AddDefaultCharset UTF-8    but that did not do anything.
I checked my mySQL database, all the tables involved. They were already at UTF-8 (default). However, some of the 'varchar' columns were defined as 'latin 1-default collation'.   I changed them all to utf-8 (default table collation), but that did not help either.
Finally, I found the problem, though I don't really know if it is "my" problem, or ZendAMF's problem, or Adobe's problem.
It turned out that 'some' of my data had a 'bad' character in it. Specifically, I had 'copied and pasted' some data from MS Word into mySQL Workbench. Some of the data included the 'elipsis' character - you know, when you type "..." (dot dot dot) in MS Word, it replaces the three periods with a single elipsis character. Although PHP could easily query and assemble this data into a nice object array, I noticed that that character showed up (in PHP's debugger) as a 'box' character, meaning "bad character". Thus, I guess, Zend AMF and/or FlashBuilder could not 'bring over' and/or deal with this type of character. As soon as I replace the few instances of that character with three periods, everything began to work perfectly.
So... what to do about this? I thought I was through with silly encoding/decoding of data when I left JavaScript and HTML behind in moving to FlashBuilder technology. Am I really going to have to worry about this kind of thing? Or might this be a bug/deficiency somewhere in the stack?
Thanks for your help,

Hello,
Can you call the same WS from ODI (through a data server test)?
I think you should post the WSDL file generated by the data service to the BPEL Forum.
There must be something BPEL does not like in the WSDL.

Exception in get_Monitor_Log/get_Error_Log after Data Services Batch error

I have a Data Services Job that has an error (intentional to test getting logs). I submit and monitor the job through the Web Service SDK. When the job completes with error and I call either get_Monitor_Log or get_Error_Log, these methods raise an exception as follows:
org.xml.sax.SAXParseException: The reference to entity "ERROR_STEP" must end with the ';' delimiter.
I can see both logs on the DS server under Administrator/Batch.
Why can't I retrieve the error log?

YES!!! I see the problem...SAX parser must not like the &. but how do I solve this, since it's the server
that sends this in a SOAP message? Probably needs to be packaged as CDATA, not text.

Data services connectivity with Oracle 8i database

Query 1:
We are using Data services XI R3 for pulling data from Oracle 8i data soure to Oracle 10g target.
Our repository is also a 10g database.
We created a datastore for 8i source and tried to import the table.
Below is the error that we get when try to import the table:
Error: Cannot import metadata.
Oracle <....> error message for operation <OCIStmtExecute> : <ORA-00904: Invalid column name>..(BODI-1112338)
While creating datastore, we entered database type as Oracle.
We were able to import the table with same 8i source , target and repository of 10g version by using Data Integrator XI R2 tool but when we try the same thing with Data services, we are getting this error.
Any other alternative other than using System DSN?
Query 2:
Also,is there any performance impact if we use ODBC System DSN name as the data source instead of Oracle while creating data store in Data services XI R3?
We have used DSN since we were not able to import table from Oracle 7 and 8i databases(source) into repository (Oracle 10g) if we give Oracle as the data source. Target database is also Oracle 10g database.
Edited by: Amardeep Pandey on Jun 26, 2009 8:51 AM

the following issue is fixed in XI 3.2, you will be able to import the tables, but Oracle 8i and 7 are not supported oracle datastore versions, you will have to select oracle 9i in the datastore
Oracle <....> error message for operation <OCIStmtExecute> : <ORA-00904: Invalid column name>..(BODI-1112338)
no there is no other alternate than using ODBC

Table based on one data service but filtered by a second data service

Hi,
I'm fairly new to VC and have got comfortable with a few simple scenarios. However, I'm trying to apply some fundamental logic that must be possible and I'm guessing straight forward.
I have a data service that contains document type master data that comes from system A. I have a second data service that supplies a list of the document types that a particular user is able to view. This comes from system B. I want to be able to display the document type master data in a table but only the document types the user is allowed to see. Both data services contain a document type code.
If anyone can point me in the right direction I would really appreciate it. We want to use VC on my current project and this is the last piece of functionality I'm trying to prototype.
Many Thanks
Gary

Hi,
I am not sure whether you have tried to achieve your requirement using intersect operator or no. I haven't tried it before but you can give it a shot.
