Is it possible to create data control from wsdl when complextype is used
Getting DCA-40015 error when trying to create a data control from WSDL file.
The error clearly says complextype is not supported . just trying to see if there are any workarounds . because creating data control will save time in developing user interface by dragging and dropping the the data control in jsf page. jdeveloper webservice tester is able to create user interface for me based on wsdl when i run it , trying to develop the user interface using jsf pages
oracle.adf.model.adapter.AdapterException: DCA-40015: Failed to create the structure for schema element "result". The complex type definition of the element is not supported.
Hi,
I could reproduce what I did:
- created WebService from custom Pojo Model
- Made sure all entities implemented serializable
- In the WebServices Wizard, I created XML representations for my entities
- tested with OC4J WebServices tester
- Built ADF data control from WSDL file of deployed WebService
- Created dependency t project containing the POJO entities
- Selected result.xml of each method exposed in the WebService project
- In the structure window, selected "item" (result-->item)
- changed Bean class to my entity class name (absolute name)
This showed my entity in the DC palette

Create data control from java class, not see "ADF Parameter Forms" option
Hi,
I have created a Fusion Web Application (ADF) in jdev 11g. In the application model project, I created a java class. Inside the java class, I have a public method as below
public Asset [] searchAsset3(SearchTerm s) // SearchTerm is a java bean. It implements java.io.Serializable.
I created data control from my java class. After that, I see an xml file generated under the same folder of my java class. Here is the xml content.
<?xml version="1.0" encoding="UTF-8" ?>
<JavaBean xmlns="http://xmlns.oracle.com/adfm/beanmodel" version="11.1.1.53.62"

Then, in application user interface project, I created a JSPX page. From the data controls palette, I want to drag and drop the searchAsset3 onto my page. However, I don't see an option for me to choose "Create -> Parameters -> ADF Parameter Form". I only see "Create -> Methods". Unlike other public methods (e.g.searchAssetSummary and searchAsset) which have simple data type as input, I can see the "Create -> Parameters -> ADF Parameter Form" option when I drag and drop to my jspx page. Is that something I missed while creating data controls?
Thanks.
Arnold.Then, my other question is how do you do the bindings? I drag and drop the attributes from SearchTerm bean. Now the pagedef file has the AttributeValues added but my method is actually expecting one input parameter of type SearchTerm. How do you bind the attributes to the input of the method? Thanks.
See below of my pagedef xml file.

How to generate web svc data control from WSDL in 10.1.3 to secure web svc
When I try to connect to web service via https, I get the error:
WARNING: Unable to connect to URL: https://remove.site.com/service
java.security.PrivilegedActionException: javax.xml.soap.SOAPException:
Message send failed: javax.net.ssl.SSLException: SSL handshake failed:

java.security.PrivilegedActionException: javax.xml.soap.SOAPException:

Process exited with exit code 0.
There does appear to be this dependency on Oracle Wallet, which I saw when I set:
System.setProperty("HTTPClient.log.level","1");
which showed Using Wallet:
and nothing after it.
AFTER I set:
System.setProperty("javax.net.ssl.Keystore", "f:\ewallet.p12");
System.setProperty("javax.net.ssl.KeyStorePassword","mywallet12");
I saw the "wallet" being used, but still ended up with the same error. I'm only trying to use the "test client" that the web service "generate web service proxy" produces.
The stack trace was:

... 2 moreIronically, the same certificates that I loaded into the java keystore using Keytool and 10.1.2 connect to the same service without an error, using the notes as described here:
http://andrej.racchvs.com/archives/2004/04/
and
http://radio.weblogs.com/0132036/2004/02/13.html
When I created the data control for the WSDL in 10.1.2 (jdev), I didn't end up with as many files and only needed to set two system properties, and change the following lines to use Apache SOAP and I could invoke the web service as a data control as well:
1. references to OracleSOAPHTTPConnection changed to:
SOAPHTTPConnection
// import oracle.soap.transport.http.OracleSOAPHTTPConnection;
import org.apache.soap.transport.http.SOAPHTTPConnection;
2. comment out:
setTransportProperties
getTransportProperties
How can you connect to a remote web service using HTTPS with JDeveloper 10g and use the Oracle wallet?
Can someone provide specific steps to get it working based on having a WSDL file to start with?

Process exited with exit code 0.
And I am working without Proxy Server.
The steps I have done to obtain the keystore are:
1) Obtain the certificate from https://secure-ausomxgfa.crmondemand.com/Services/Integration and save as .cer
2) With this certificate I have generated the keystore:
C:\jdevstudio1013\jdk\jre\bin keytool -import -v -f DIR_CERTIFICATE_DOWNLOADED -keystore server.keystore -keypass PASS -storepass PASS_FROM_server.keystore
PASS=I have put an invented password
Any idea to solve the error? Is necessary a certificate with a keystore to connect HTTPS Web Service from JDeveloper 10g?
Thank you an regards.

Not able to access SOAP web service data control from adf mobile
Hi,
I am trying to call web services from adf mobile..
I have created data control from external web service and it is perfectlly working on web browser..
But why it is showing an error on emulator??
Is there any .jar file missing in adf mobile so that it is not supporting a web service?
Or is there any other problem? Emulator is connected to network and I am able to run WSDL in emulator's browser..
Please help me to solve this issue..
Thanks,
LaxmiEmulator is connected to network and I am able to run WSDL in emulator's browser..
Connecting to WSDL in the browser is not the same as connecting to WSDL in an application.
To access a web service from an Android device enable a permission in AndroidManifest.xml that allows applications to open network sockets. Add the following uses-permission element.
<uses-permission android:name="android.permission.INTERNET"></uses-permission> -
Create Data Control not showing in EJB Session Bean context menu
Hi All,
I've been studying the new Oracle Application Development Framework Tutorial for 10g Release 3 (10.1.3). When I get to page 2-16 (page 31 of the PDF doc) it says to create ADF Data Control. Specifically is says " In the Applications Navigator, right-click the SRPublicFacadeBean.java node and choose Create Data Control from the context menu."
But my context menu doesnt have the Create Data Control option. I double checked that I didn't miss a step in the tutorial. I'm sure it's something simple. Can anyone point me in the right direction? Is there another way to create the Data Control for an EJB Session Bean?
Thanks,
CaryI downloaded "jdevstudio1013.zip " and I still don't have this context menu?
What are the steps to correct this?
Thanks,
--Todd
Figured it out. I was having an extension issue and I had to turn off all of my extensions. Thus, turned on the ADF extension (duh!) and all was well.

Create data control button missing from menu
I'm using Jdeveloper 11.1.2
1. I create a new Application
2. create a new JavaClass under viewController
3. right click the class
and...
I can't find the create data control button and create webservice button
I do the same operation on another computer , it appears !
why ?
is ther any settings I need to turn ?If you do not bother about loosing your current IDE preferences then close/kill jdev and try deleting the jdev system directory. Start jdev again.

Exception while creating Data Control
Good day house,
I have been doing some research on using business components design in other IDEs with Oracle ADF faces within JDeveloper 11g.
I went through the following steps
create a Java EE web application - a model and viewcontroller project
imported my EJB project jar file - but I could not get an icon to show me the beans within my jar, so I imported the source instead
On importing the source, I right click on my bean classes and chose create Data control but it comes with an exception

2. Why the exception? Is it a problem with my JDeveloper installation?
3. Is it also possible to create a data control from any plain java object/interface.
thanks in advanceDid you create the weblogic domain with the Oracle Webcenter Spaces option selected? This should install the relevant libraries into the domain that you will need to deploy your application. My experience is based off WC 11.1.1.0. If you haven't, you can extend your domain by re-running the Domain Config Wizard again (WLS_HOME/common/bin/config.sh)

Getting Extra classes while creating Data Control in ADF
I am using Jdeveloper 11.1.1.6.0.
I was trying to create a Data Control from a Java class (containing event handling code) right click on the java class -> Create data Control.
I can see many data controls were created in my work space when the operation was completed
Example: java.io.InputStream.xml, java.net.URI.xml and many more.
Anybody please suggest is it a problem in Jdeveloper tool or I need to perform any additional step to remove all these files.
Regards,
RajeshHello TimoHahn,
I can see only the Data controls are getting generated (not the class files).
Please find the code snippet for my class for which I generated data controls:
public class ContexEvent {
public ContexEvent() {
super();
public void handleEvent(ActionEvent payload){
UIComponent component = payload.getComponent();
Map<String, Object> attrMap = component.getAttributes();
FacesContext context = FacesContext.getCurrentInstance();
ELContext elContext = context.getELContext();
Application application = context.getApplication();
ExpressionFactory factory = application.getExpressionFactory();
ValueExpression valueExpr = factory.createValueExpression(elContext, "#{backingBeanScope.NameBean}", Object.class);
NameBean nb=(NameBean)valueExpr.getValue(elContext);
//String newVal = (String)payload.getNewValue();
nb.setFirstName("Rajesh");
AdfFacesContext adfContext= AdfFacesContext.getCurrentInstance();
adfContext.addPartialTarget(nb.getNameLabel()); -
Using JDev 11gPS4
I have a java class that i want to use as a DC:
(simplified)
public class AccountDC {
public AccountDC() {
super();
public void insertAccount(Account account){
//Do some things
}Account:
public class Account {
private String name,alias;
public Account() {
super();
public void setName(String name) {
this.name = name;
public String getName() {
return name;
public void setAlias(String alias) {
this.alias = alias;
public String getAlias() {
return alias;
}When I create the data control from the first class, i get the insertAccount operation.
When i drop the account parameter on my JSPX page, JDev suggest an ADF Form which is fine.
When I drop the insertAccount method below the form, JDev suggest an ADF Button which is also fine.
JDeveloper doesn't seem to know that the values provided in the above form should be mapped to an Account object for the insertAccount.
How should I do this?
In the bindings I do have the individual attributeValues for each attribute but I don't seem to have a reference to an Account object. Do i need to add something to my DC?
Another question... Is it maybe better to create a VO with only transient attributes and an Application Module where i expose my own custom createInsert method?
It's all custom code. It does not write anything to a database.You should have an object that represent your method's parameter in your data control - if you'll drag it into your page you'll get the fields needed.
Similar to the way it is done in this example:

Is it possible to delete data selectively from Business content cubes
Dear Experts,
Requesting you to help me out to know, is it possible to delete data selectively from Business content cubes.
When I'm trying to delete selectively from Business content cubes, the background job gets cancelled with ST22 logs stating
A RAISE statement in the program "SAPLRSDRD" raised the exception condition "X_MESSAGE".
Since the exception was not intercepted by a superior program, processing was terminated.
and i tried with few more Technical content cubes but the same thing happens.
Pls let me know how to selectively delete data from Business content cubes if it's possible?.
Thanks in advance for your favorable assistance.
Regards,
Ramesh-Kumar.Hi Ramesh,
Follow below steps for selective deletion:
1. Transaction code: Use the Transaction code DELETE_FACTS.
2. Generate selective deletion program:
A report program will be generated of the given name, here .
3. Selection screen:
Take the deletion program u201CZDEL_EPBGu201D to the transaction code SE38 to see/execute the program.
After executing it will take you to a selection screen:
As we need to carry out deletion selective on Calendar week, we need to get the screen field for the field Calendar week. For this, click on the Calendar week field and press F1.
Click on the technical information button (marked in red box above) you will get below screen:
ABAP program to carry out the Calendar week calculation
Problem scenario: As stated earlier the requirement is to delete the data from the cube based on the calendar week. Thus a code must be developed such that the number of weeks should be taken as input and corresponding calendar week should be determined. This calendar week should be then passed to the deletion program in order to carry out the data deletion from the InfoCube.
Transaction code: Use T-code SE38 in order to create a program.
Logic: Suppose we need to delete the data older than 100 weeks.
a. Get the number of weeks and system date in variables and calculate the total number of days :
lv_week = 100. *number of weeks
lv_dte = sy-datum. *system date
v_totaldays = lv_week * 7. *total days
b. Get the corresponding calendar day from the total days. This is obtained by simply subtracting the total no. of days from the system date.
lv_calday = lv_dte - v_totaldays. *corresponding calday.
c. Now in order to get the calendar week corresponding to the calculated calendar day we must call a function module 'DATE_TO_PERIOD_CONVERT'. This function module takes input as Calendar day and Fiscal year variant and returns the appropriate fiscal period.
Get the sales week time elements
call function 'DATE_TO_PERIOD_CONVERT'
exporting
i_date = lv_calday
i_periv = lc_sales
importing
e_buper = lv_period
e_gjahr = lv_year
exceptions
input_false = 1
t009_notfound = 2
t009b_notfound = 3.
if sy-subrc = 0.
ls_time-calweek(4) = lv_year.
ls_time-calweek+4(2) = lv_period.
endif.
v_week = ls_boots_time-calweek.
Note: We can pass the fiscal year variant which can be obtained from the table T009B.For e.g. here fiscal year variant lc_sales = Z2. LS_TIME will be any table with suitable time units.
d. Now we have obtained the required calendar week in the v_week variable. This calendar week is the week till which we need to keep the data. And older data than this week will be deleted. This deletion will be done by the deletion program
Submitting the Data deletion program for ZEPBGC01 and key field
SUBMIT ZDEL_EPBG WITH C039 LT v_week.
Here the calendar week value is submitted to the deletion program ZDEL_EPBG with the screen field of calendar week.
Hope ... this will help you..
Thanks,

Calling Data Control from Session bean
Is it possible to use workshop data control from with in Session bean.
If the client code is located in the same "deployment unit" (e.g. EAR
file) as the EJBs, then you can pass the data by reference.
Serialization is required when crossing between deployment units. This
is required to support redeployment.
Hyung-Jin Kim wrote:
I recently downloaded WL6.0 and I noticed that when a
session bean returns data to its client, the data is
always serialized back the client -- EVEN it the client
is on the same machine. Ideally, I would prefer that a
reference to the data simply be returned to the client.
Does the serialization occur because WL6.0 put session
beans in its own ClassLoader or does the serialization occur
because of the way WL6.0 compiles the RMI stubs? Thanks
for your response.

Create Data Control does not work?!
I created an application with JSF,EJB,TopLink JPA technology template.
Two projects were generated, EJBModel and View Controller. So far so good.
In EJBModel project I generated 6 entities from 6 db tables. I also created a native query in orm.xml and created a result class entity to take the result of this native query.
I generated session EJB facade and added a method to invoke above native query.
I also generated EJB client from this facade to test it.
I run both to ensure query works as expected and it did.
I then right clicked on session EJB facade and selected option Create Data Control.
JDev pop-ed up two windows: one window to Choose EJB Interface dialog and on top of this one another window with title "Create Data Control" and with message "Creating data Control..." stuck forever. I could not remove nor stop this window executing, I had to kill JDev in Task Manager.
Is this a known thing and is there a workaround? This is kind of urgent, any help is appreciatedI returned to 10.1.3.2. and created the same application, but got bunch of exceptions which forced me a couple of weeks ago to switch to 11g Preview environment:

Hey guys
i need to create Data Type from and XSD,in the beginning i had an XML document which i converted to XSD using Altova ,then i imported this XSD in IR under External definition,now how should i go ahead with creating Data Type?
my sample XSD is something like this
<?xml version="1.0" encoding="UTF-8"?>
<!W3C Schema generated by XMLSpy v2007 sp2 (http://www.altova.com)>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:simpleType>
<xs:restriction base="xs:int">
