Webservice return type

Dear All,
I have a web service with return type as array.
I need to return dynamic array.Is there any alternate way to this.
Could anyone help me regarding this.
Thanks & Regards

On xMII XML format via the WebService (WSDLGen) mechanism, but you can return any xMII XML format via the Runner mechanism.
URL is something like: /Lighthammer/Runner?Transaction=YourTransaction&OutputParameter=DesiredXMLOutputParameter
There are more complex techniques that can be used to have xMII emulate any webservice with any inputs and outputs, but those involve creation of custom WSDL files and are probably a bit lengthy for an SDN post.

How to create a webservice with return type File

Hi All,
I have a class Letter and I am trying to expose viewReport as webservice.
In Jdeveloper -> Business teir -> webservices -> Java web service and I have selected my method i.e. viewReport
Now it throws error "The return type java.io.File of method viewReport can not be serialized into XML"
I unserstood the issue but How can I achive this in JDeveloper
public class Letter {
public Letter() {
super();
public File viewReport(String name) {
File folder = new File("C:\\APPS\\root\\pdf\\10052011");
File[] listOfFiles = folder.listFiles();
return listOfFiles[0];
}

You can't as File is nor serializable. It won't make sense as you would try to give a handle to a file on the server hosting the service to a remote system.
Can you explain the use case in more detail?

Stub generated in Jdev9i for webservice with 'Vector' return type

Hi,
In the OAF page that I am developing, I am trying to consume a web service generated in SAP PI using Jdeveloper. My Jdeveloper version is 9.0.3.5(I need to use this version since I need to deploy the OAF page in EBS11i). The stub generated based on the WSDL is given below.
import oracle.soap.transport.http.OracleSOAPHTTPConnection;
import org.apache.soap.encoding.soapenc.BeanSerializer;
import org.apache.soap.encoding.SOAPMappingRegistry;

import org.apache.soap.Envelope;
import org.apache.soap.messaging.Message;
* Generated by the Oracle9i JDeveloper Web Services Stub/Skeleton Generator.
* Date Created: Tue Jan 25 16:12:55 IST 2011
* WSDL URL: file:/C://Working/XXXXXXX/RegConsComplaint_OB.wsdl
public class RegConsComplaint_OBServiceStub
public RegConsComplaint_OBServiceStub()
    m_httpConnection = new OracleSOAPHTTPConnection();
public static void main(String[] args)
    try
      RegConsComplaint_OBServiceStub stub = new RegConsComplaint_OBServiceStub();
      // Add your own code here.
    catch(Exception ex)
      ex.printStackTrace();
public String endpoint = "http://XXXXXX:8000/sap/xi/...../RegConsComplaint_OB";
private OracleSOAPHTTPConnection m_httpConnection = null;
private SOAPMappingRegistry m_smr = null;
public Vector RegConsComplaint_OB(Element requestElem) throws Exception
    URL endpointURL = new URL(endpoint);
    Envelope requestEnv = new Envelope();
    Body requestBody = new Body();
    Vector requestBodyEntries = new Vector();
    requestBodyEntries.addElement(requestElem);
    requestBody.setBodyEntries(requestBodyEntries);
    requestEnv.setBody(requestBody);
    Message msg = new Message();
    msg.setSOAPTransport(m_httpConnection);
    msg.send(endpointURL, "http://sap.com/xi/WebService/soap1.1", requestEnv);
    Envelope responseEnv = msg.receiveEnvelope();
    Body responseBody = responseEnv.getBody();
    return responseBody.getBodyEntries();
}I am wondering whether I will be able to use this stub generated by Jdeveloper since the input type is 'Element' and return type is 'Vector'; while in the Jdeveloper documentation the supported "primitive XML Schema types and arrays of primitive XML Schema types as parameters and return values for web services" do not include either of the two.

How to know return type in Web service

{color:#0000ff}I am writing a web service client application. After invoking the service it gets the result as SOAP massage. But i need to know the return type also. How can i do that?
{color}
here is the response obtained from web service after invoking a subtract method, it is giving correct value but doesn't give tye of value.
<ns:SubtractResponse xmlns:ns="http://example.ws"><ns:return>81</ns:return></ns:SubtractResponse>

View WSDL(Web Service Description Language) file of the web service. Normally WSDL file of any web service can be referenced by appending "wsdl" at the end of web service URL. e.g. http://www.abs.com/mywebservice/invokewebservice?wsdl
Shazzad wrote:

How can i do that?WSDL file for a web service contains all information regarding the web service like types, message, portType, binding, service etc. Types section have schema definitions of all messages which are being used in web service. here you can find everything about all elements, fields for all the messages in the WebService including type of the values.
You can find more about WSDL on Sun and Google very easily.
Hope this will help.

Premature EOF encountered with Document as a return type

I have created a web service that returns a Document object. I have successfully deployed the web service to my local OC4J standalone (9.0.3), and tested it within JDeveloper with a stub. The same web service is deployed to our test server running 9iAS 9.0.2, with OC4J 9.0.2. When I change my stub to point to the test server, I get the following error rather than the Document returned:
[SOAPException: faultCode=SOAP-ENV:IOException; msg=Premature EOF encountered; targetException=java.io.EOFException: Premature EOF encountered]
Thinking this was a OC4J version issue, I installed 9.0.3 standalone on the same machine. I am able to navigate to the web services page for my web service successfully, invoke the web service, and see the correct Document embedded within the SOAP response. I was unable to do this on the 9.0.2 OC4J instance. Unfortunately, I get the same error when running the stub from JDeveloper and pointing to the 9.0.3 web service.
In an probably unrelated note, I am trying to use the web services portlet, pointing to my stub to call my web service. With this, I get the following error:
ERROR: Failed to handle HTTP Request

Thinking this is an xmlparser version issue, not sure which parser is taking precendence, the OC4J_Portal parser, my application parser, or the ORACLE_HOME parser.
I have thrashed on these issues for a little while, and hopefully I have missed something obvious here. Anything jump out at anyone?
Thanks!

Mike,
Thanks for the response. The reason I am inclined to use Document as a return type is for reuse. Our system is based on the creation of Document representations of content to be displayed, and we use framework code to transform given an xsl. I am trying to establish a pattern for publishing web services right from our existing processes that return the Document. I did play with Element, but would rather not go that way.
I think my web service is working fine now, actually. (Why it can't be tested from JDev, I'm not sure. I will try the server side proxy as you suggest). It is returning my xml content within the <return> of the response. The problem is transforming the result with an xsl. I have tried the web services portlet, which won't work for me because of my return type, and I'm now trying the OmniPortlet, which seems to be coming tantalizingly close to working ;). Not sure if you have used the OmniPortlet or not, but running it, I can see the return of the web service with my xml, which looks good, but then I get this error:
3/12/03 8:55 AM omniPortlet: [id=(null), instance=3915_OMNIPORTLET_49587206] XMLData.next => o
racle.webdb.reformlet.ReformletException: Error occured while fetching XML data.
Also, I've had problems getting the OmniPortlet to recognize my xsl filter for the xml being returned.
Anyone have any success using OmniPortlet consuming a web service that returns xml to be transformed with an xsl filter?
Thanks,
Jason

Exception in Holder for Multiple Return Types

Hi,
I am implementing multiple return types as mentioned at url: -

What? How is this ugly? ;-)

or, stateAnimal, governorsName;
there no indication on what the return valuesrepresent.
Well, I guees the API docs would have to speak for

sense, it's no different then now. I could write a
method "getStateName()" and return totally different.
public String, int getStateNameAndPopulation(String

I used to like "tuples" when I studied The Tom Programming Language (that's how he calls them), as every CS student is a bit of a "featurist"... Now that I came to develop 40 hours a week and to love Java's simple and powerful expressiveness, I tend to find such constructs overly ugly to be avoided as possible... a matter of personal taste, too, I suppose...

Could anyone help me, thanks

Here is a the actual php class:
class question{
function getQuestionDetails()
$r = array("r"=>"s","t"=>11230,"wr"=>500);
return $r;
This class has a defined return VO(questionDetails) in flex. It is recognized in the IDE, but when I run the app, I always get a "null object reference" error. I can't seem to convert the result to questionDetails, and I can't access the fields as properties or part of an array of the return object as an instance of "Object".
Any ideas?
Thanks!

Multiple Return Types

haven't been around in a while, so I thought I'd stir up some comments with a suggestion for a new feature in Java, which I'm sure has been suggested at some point, but I can't remember seeing it talked about, so here goes:
Multiple Return Types:
public String, int getStateInfo(String abbrev) {
   if("nj".equalsIgnoreCase(abbrev)) {
      return "New Jersey", 11408042;
   // ... and other states...
   return null, -1;
String name, int population = getStateInfo("nj");
System.out.println("The population of " + name + " is " + population + ".");Yes yes, I know. Create a StateInfo object with the fields needed. Still, I think that could be interesting.

apart from it getting ugly with more than twoparameters

How can I get rid of a type generated by the Data/Services return type wizard?

Hi All,
I have a JSON service that returns an object called "error". The Data/Services "Configure Return Type" wizard automatically turned this into a class "Error".
However, this caused over a hundred errors to show up inside the generated classes, "Call to a possibly undefined method Error." That's because of lines like this:
throw new Error(propertyName + " is not a data property of entity Agreements");
It's trying to throw a regular "Error" object, but now that there's an "Error" class in the same package, that is taking precedence--and that Error object doesn't have a constructor with a single parameter. At least, that's what I think is going on.
I tried to fix it by deleting _ErrorEntityMetadata.as, _Super_Error.as, and Error.as from the valueObjects package. I then opened the FML file and deleted the definition for the entity "Error" and every reference to the Error entity (class) in my FML file.
I then changed my JSON service so that it returns an object called "serviceError" instead of just "error".
But, whenever I re-run the "Configure Return Type" wizard, it regenerates the Error class, even though I've deleted it from everywhere I can find it. That breaks my project completely! How can I end this and get Flash Builder to *stop* generating this type!
In the "Configure Return Type" wizard I very carefully inspected the type of every bit of data coming back to make sure none of them show up as type "Error." And they don't (as expected, since I changed the object's name to serviceError--now the type of that object is ServiceError.
-Josh

I think you are facing this known issue https://bugs.adobe.com/jira/browse/FB-29770
Please vote it.
Thanks for the link--I just voted for it.
To avoid this, in the last page of "Configure Return Type", edit return type name to something else (You can also edit subnodes's name too in the wizard).
Actually, that's exactly what I saw doing; I apologize if that wasn't clear in my post.
I closed and restarted Flash Builder, and once I did that Flash Builder stopped generating the Error class. My guess is that the FML file, even though I had updated it (by deleting all references to the Error class), was cached in some fashion by Flash Builder, and restarting Flash Builder forced it to reread the FML file?
Additional point of clarification: my understanding is that the FML file stores all the metadata about the services that Flash Builder has been able to figure out so far, and when you run the Configure Return Type wizard, it will regenerate *every* type in the FML file, even if that type is not mentioned anywhere in the particular return value that you are working with.
Edited to provide additional thoughts on FML file.

Problem when calling a return type BOOLEAN SQL Function in a package

Hi All,
I am having problem when trying to call a SQL function in a package with return type BOOLEAN
The SQL function signature is as follows
CREATE OR REPLACE PACKAGE RMSOWNER.ORDER_ATTRIB_SQL ****
FUNCTION GET_PO_TYPE_DESC(O_error_message IN OUT VARCHAR2,
I_PO_TYPE       IN     VARCHAR2,
O_PO_TYPE_DESC IN OUT VARCHAR2)
RETURN BOOLEAN;
Following is my java code
+CallableStatement cs3 = conn.prepareCall("{?=call ORDER_ATTRIB_SQL.GET_PO_TYPE_DESC(?,?,?)}");+
+cs3.registerOutParameter(1, java.sql.Types.BOOLEAN);+
+cs3.registerOutParameter(2, java.sql.Types.VARCHAR);+
+cs3.registerOutParameter(4, java.sql.Types.VARCHAR);+
+cs3.setString(2, "");+
+cs3.setString(3, "ST");+
+cs3.setString(4, "");+
+ResultSet rs3 = cs3.executeQuery();+
I get the following exception, i tried changing the sql type(registerOutParameter) from boolean to bit but i still getting this exception.
But when i call any other functions with return type other than boolean they work perfectly fine.
Please can anyone help me fix this issue, i am not sure if its anything to do with vendor JDBC classes?

Hello People!
There is another workaround!!
See the example below:
private String callBooleanAPi(String tableName,String apikey,String dtInicio,String dtFim,String comando) throws SQLException {
               CallableStatement cs = null;
               String call = "";
               String retorno = null;
               try {
                    if(comando.equalsIgnoreCase("INSERT")){
                         call = "declare x BOOLEAN; y varchar2(2);begin x :=PKG.INSERT(?,?,?,?,?); if x then y := 'S'; else y :='N'; end if; ? := y;end;";
                    } else if(comando.equalsIgnoreCase("UPDATE")){
                         call = "declare x BOOLEAN; y varchar2(2);begin x := PKG.UPDATE(?,?,?,?,?); if x then y := 'S'; else y :='N'; end if; ? := y;end;";
                    } else if(comando.equalsIgnoreCase("DELETE")){
                         call = "declare x BOOLEAN; y varchar2(2);begin x := PKG.DELETE(?,?,?,?,?); if x then y := 'S'; else y :='N'; end if; ? := y;end;";
                    cs = conn.prepareCall(call);
                    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
                    SimpleDateFormat sdfToSqlDate = new SimpleDateFormat("yyyy-MM-dd");
                    java.util.Date dataInicialVigencia =null;
                    java.util.Date dataFinalVigencia = null;
                    Date dtInicialFormatada =null;
                    Date dtFinalFormatada = null;
                    if(dtInicio != null && !dtInicio.equals("")){
                         dataInicialVigencia = sdf.parse(dtInicio);
                         dtInicio =sdfToSqlDate.format(dataInicialVigencia);
                         dtInicialFormatada = Date.valueOf(dtInicio);
                    if(dtFim != null && !dtFim.equals("")){
                         dataFinalVigencia = sdf.parse(dtFim);
                         dtFim =sdfToSqlDate.format(dataFinalVigencia);
                         dtFinalFormatada = Date.valueOf(dtFim);
                    cs.setString(1, tableName);
cs.setString(2, apikey);
cs.setDate(3, dtInicialFormatada );
cs.setDate(4, dtFinalFormatada );
cs.registerOutParameter(5, java.sql.Types.VARCHAR);
cs.registerOutParameter(6, java.sql.Types.VARCHAR );
cs.execute();
                    retorno = cs.getString(6);
                    System.out.println( cs.getString(5));
               } catch(SQLException e){
               throw new SQLException("An SQL error ocurred while calling the API COR_VIGENCIA: " + e);
               } catch(Exception e){
               Debug.logger.error( "Error calculating order: " + id, e );
               } finally {
               if (cs != null) {
               cs.close();
               cs = null;
               return retorno;
As you can see the CallableStatement class acepts PL/SQl blocks.
Best Regards.

Should Collections be used as return types across threads?

I am wondering when, if ever, it is appropriate to use a Collection as the return type of a method in a multi-threaded environment. Here is our situation:
We have four classes -- Widget, WidgetManager, ClientA, and ClientB. ClientA and ClientB are running in different Threads from each other and from the WidgetManager.
The WidgetManager class that uses a Collection of Widgets internally, and passes the Collection (or an Iterator over it) out as a return value of a method to ClientA, which is running in another thread. ClientA would start to go through it using next() and hasNext() of the Iterator. If the WidgetManager were to get a request from ClientB running in another thread to eliminate a Widget, it would attempt to remove it from the Collection. If ClientA were still looping through the Iterator, this would throw an IllegalStateException b/c the system would be in an inconsistent state. The Iterator given to the ClientA is directly linked to the actual Collection in the WidgetManager (am I right so far?).
In my opinion, in most cases we don't want to synchronize Collections. In the example above, if we had passed out a synchronized Collection, then the WidgetManager couldn't touch the collection while the client was looping through the Iterator. If the client got hung up while looping, then the WidgetManager would be hung up. In this case, I think that it will be better to use the toArray() method of Collection to just dump out the contents to a plain array of Objects. Actually, the WidgetManager could convert this array of Objects to an array of Widgets before passing it out, which would give us the type checking that we don't get with Containers.
The condition where you would want to use a synchronized Collection would be when you actually want the client to do some writing or removing from the Collection. I would expect this to be pretty rare since you usually dont want to give clients access to an interal member (the Collection) of a class.
I think that it is also possible to have read-only Collections, but I think (don't know for sure) that you would still have the same IllegalStateException or synchronization probelms.
Can someone point out the errors in my thinking? Or should you generally only use Collections as internal members in a multi-threaded environment, and use toArray() whenever you want to pass the Collection's data outside of the class?
Thanks for any help.

I haven't tested what happens when you synchronize the
Collection, but I think that you are right. But this
causes the problem that I mentioned in the first post.
That is, what happens if your client STARTS running
through the Iterator, and then stops or gets hung up
for some reason? I assume that you're still blocked.
And it's pretty important to me in this case to not
t be blocked -- WidgetManager is the highest level
class in the system.
I'd like to know if anyone has tested this.
The Iterator implementations used in java.util do not use any synchronization by itself, (which is what you would expect since synchronization over multiple method call will involve much more complications and slower performance) . With iterator, you have to provide the necessary synchronization yourself to maintain thread-safety like this
Iterator itr = get Iterator from collectionInstance ;
synchronized(collectionInstance) {
while(itr.hasNext())
process itr.next() ...
As long as your client code gracefully exits the synchronized block on a stop( or hangup, given that it is detected and handled fast enough), it will not be a problem.
Also, I'd like an example of when you WOULD want to
return a Collection. I'm specifically interested in
when you would want to return one in a multi-threaded
environment, but I'm beginning to wonder when you
would EVER want to return one from a method.
Collections are great for internal uses, but you lose
type-checking and you expose the internals of your
class to modification when you use them as return
types. And if you're returning a read-only
Collection, you might as well return an array, right?Using a read-only proxy will be much faster and space-efficient than toArray().

Two methods with same name but different return type?

Can I have two methods with same name but different return type in Java? I used to do this in C++ (method overloading or function overloading)
Here is my code:
import java.io.*;
public class Test{
public static void main(String ar[]){
try{
//I give an invalid file name to throw IO error.
File file = new File("c:/invalid file name becasue of spaces");
FileWriter writer = new FileWriter(file ,true);
writer.write("Test");
writer.close();
} catch (IOException IOe){
     System.out.println("Failure");
//call first method - displays stack trace on screen
     showerr(NPe);
//call second method - returns stack trace as string
        String msg = showerr(NPe);
        System.out.println(msg);
} // end of main
public static void showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     String stackTrace = sw.toString();
     System.out.println("Null Ptr\n" + stackTrace );
}//end of first showerr
public static String showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     return sw.toString();
}//end of second showerr
} // end of class
[\code]

Overloading is when you have multiple methods that have the same name and the same return type but take different parameters. See example
public class Overloader {
     public String buildError(Exception e){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( e.getClass().getName() )
               .append( " : " )
               .append( e.getMessage() ) ;
          return buffer.toString() ;
     public String buildError(String msg){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( msg ) ;
          return buffer.toString() ;
     public String buildErrors(int errCount){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( "There have been " )
               .append( errCount )
               .append( " errors encountered.") ;
          return buffer.toString() ;
}Make sense ???

The class of the deferred-methods return type "{0}" can not be found.

I am developing a multilingual portal application.
I have the method that changes the locale based on user's choice in the bean and the method is being referred to as below.
<af:selectOneChoice label="Select Language" autoSubmit="true"
value="#{localeBean.locale}"
valueChangeListener="localeBean.changeLocale">
<af:selectItem label="English" value="en" id="si1"/>
<af:selectItem label="French" value="fr" id="si2"/>
<af:selectItem label="Dutch" value="nl" id="si3"/>
</af:selectOneChoice>
when i try to run the application, i am getting compile time errors as below,
The class of the deferred-methods return type "{0}" can not be found.
No property editor found for the bean "javax.el.MethodExpression".
After going through the discussion forums i learned that the compilation errors can be resolved by setting the <jsp:directive.page deferredSyntaxAllowedAsLiteral="false> at the starting of the page.
Even after that i am getting the compilation error.
Any solutions, suggestions or possible approaches would be helpful as i am new to Webcenter Portal development.
Thanks,

The error you get points to a problem on the page (somewhere). Switch to source mode and check the right margin if you see orange or red marks. These are pointing to problems (not all are show stoppers, but they give you hints that something is not according to the standard for jsf, jsff, jsp or jspx pages.
Have you checked that the bean is correctly defined and that it's reachable?
Start a fresh page and isolate the problem, e.g. build a selectOneChoiuce on the new page (don't copy it as you might copy the error too) and make it work on the new page. Once you have it running you can compare the solution to your not running page.
