Problem with a Web Service execution of a Matlab converted program

Hello,
I need my Java Web service to call a program developed in Matlab. I've created a C++ shared library from my test.m file using the cpplib wrapper, with the following command: mcc -W cpplib:libtest -T link:lib test.m
I've then created another file which I called another.cpp to use the shared library. I've done so using the following two commands:
g++ -c -I/usr/local/matlab/extern/include -I. another.cpp
g++ -O -o another another.o -L. -ltest
Until this point, everything is ok and I've obtained my compiled file "another". However, when I try to execute the file, the system requests for some shared libraries, which should be pointed out through the LD_LIBRARY_PATH environment variable. Everything works fine changing the variable in the shell. I can execute "another" without any problem. The problem arises when I try to execute the file through my Web Service. I started by developing a script which would export the LD_LIBRARY_PATH and execute "another". The idea was to have the Web Service call the script, but it didn't work. I've tried to solve the LD_LIBRARY_PATH problem by using the following command:
g++ -O -L. -o another another.o -Wl,-rpath=/usr/local/matlab/bin/glnx86 -Wl,-rpath=/usr/local/matlab/sys/os/glnx86,-rpath=. -ltest
This allows me to have an executable "another" with no other shared library needs... However, whenever I compile my "another" with "-Wl...", my Web service just does not execute the file. The problem still remains! Just to be sure, I have executed successfully other c++, using the same compiler, or scripts files from my Web service. But for Matlab programs, I need to use the libraries I referred above in "-Wl".
I've been with this problem for quite a while now, and I still haven't found a way of solving it. Can anyone help me?
Thank you,

Problem with RESTful web service

I am running into a problem with Flex Web Services (REST) in trying to get the proper format returned. I can see that the HTTP header is set to
Accept: */*;
rather than
Accept: application/xml
when sending the request. The web service was generated via the web services HTTP data services wizard. I edited it to set the resultFormat to xml
    // Constructor
    public function _Super_UsersService()
        // initialize service control
        _serviceControl = new mx.rpc.http.HTTPMultiService();
         var operations:Array = new Array();
         var operation:mx.rpc.http.Operation;
         var argsArray:Array;
         operation = new mx.rpc.http.Operation(null, "getUsers");
         operation.url = "http://localhost:8888/users";
         operation.contentType = "";
         operation.method = "GET";
         operation.resultFormat = "xml";
         //operation.serializationFilter = serializer0;
         operation.properties = new Object();
         operation.properties["xPath"] = "/";
         operation.resultType = valueObjects.Users;
         operations.push(operation);
         _serviceControl.operationList = operations;
         model_internal::initialize();
How does one configure the accept header?

Hi,
I have posted a simple application with the RESTful reference:
http://apex.oracle.com/pls/apex/f?p=13758
I can give you full privileges on this so you can look at the WEB service reference. Shall I send to you separately for login user?
It is using the RESTful service: http://apex.oracle.com/pls/apex/nd_pat_miller/demo/employee/{deptno}
This RESTful service tests fine when I test from within the RESTful web service module of the Workspace.
I based this on the Video demo tutorial for RESTful web service that Oracle published for 4.2 release. The video seemed to exclude the {deptno} in the URL but when I try that, it doesn't work either.
This is the error I am getting when I run this on my Apex environment: (it, of course, will not run the web service in the apex.oracle.com environment)
class="statusMessage">Bad Request</span>

Problem with CFMX web service function return

I made a post yesterday about a web service function I was
writing, as it turns out my post was extremly incorrect for my
problem. With this web service function I can return an array just
fine, I can return one instance of an object just fine, however,
when I try to return an array of the object I keep getting the
error:
Could not perform web service invocation "SelectGames"
because AxisFault faultCode: {
http://schemas.xmlsoap.org/soap/envelope/}Server.generalException
faultSubcode: faultString: [org.apache.axis.AxisFault : ; nested
exception is: coldfusion.xml.rpc.CFCInvocationException:

nested exception is: coldfusion.xml.rpc.CFCInvocationException:

which basically means that the CF server needs restarted.
However if I restart the CF server, no matter how many times I am
still getting this error. If I change up my web service function to
return just a normal array of integers or strings, or I change it
to return one instance of the arbritrary complex type it all works
just fine. I am still a little new on this subject and any
enlightenment would be great. If anyone has found a way around this
please let me know.
Here is my complex type:
<cfcomponent>
<cfproperty name="Game_id" type="numeric">
<cfproperty name="gameDate" type="date">
<cfproperty name="Starttime" type="string">
<cfproperty name="Place" type="string">
<cfproperty name="Level" type="string">
<cfproperty name="Sport" type="string">
<cfproperty name="Gender" type="string">
<cfproperty name="Opponent" type="string">
<cfproperty name="Type" type="string">
<cfproperty name="Link" type="string">
</cfcomponent>
I loop trhough a query and set a cfobject of the types above,
then I append that object to an array and try t o return the array.
Here is the basics of the loop:
<cfset theArray = arrayNew(1)>
<cfobject component = "games" name = "test>
<cfloop query ...>

<cfset arrayApend(theArray, test)>
</cfquery>
<cfreturn theArray>
my return type is array, I think the problem is I need to
specify the return type to be an array of arbritray complex types
which is impossible to do in CF. Anyone find a way to get around
this?? Any feed back at all would be greatly appreciated.

Yes, I have tried it and return type any does not work in
this situation since this function is being consumed by a web
service. It needs to be in the form of an array of arbritrary type
that is defined in a cfc file. Since this is WSDL the returntype
has to be specified to every last bit.

Problem with Oracle Web Service Proxies reusing classes and exceptions

We have an application that have many web services and we're having a really hard time working with Oracle Web Service Proxy. We have many web services that share the same classes for parameters and exceptions. When we generate de proxy classes, it generates a lot of _LiteralSerializer classes. Because I'm reusing the same classes and exceptions it generates the same _LiteralSerializer classes for this classes and they get replaced. For Example
I have classes A and B and Web Services X and Y that use this classes. When I generate the 2 proxies it generates A_LiteralSerializer and B_LiteralSerializer on the 2 proxies and they get replaced and I get "No serlalizers for A class or B class". This problems repeats a lot of times and this problem is a huge risk for our project. We're using JDeveloper 10.1.3.4.
Is there a way to avoid this with Oracle Web Service Proxies?

What is problem with my web services application?

Hi Everyone, I have a question for you.
I created a web service, and tried to call its method within a JSF application (developed by JSC2). Following is what I got:
1) It works with TravelWS example.
2) It works if I called my web services' methods from a standalone Java program.
3) It does NOT work if I call it within my JSF applicationBean1() or JSP pages.
4) After adding my own web services into my JSF through JSC IDE, I tested my methods provided by web services. Two of them are working. But rest of them do not.
If it is the problem of my web service, why my standalone Java program works?
If it is the problem of my JSF application configuration, why TravelWS example works?
What can the problem be? Can someone give me some suggestions?
Any help is appreciated.

Thanks both of you for the response.
Here is my situation. The web service is developed by another team. And we are trying to call their methods in our JSF application. From the example provided by the web service team, I need to do following in my JSF code:
myWebServiceLocator locator = new myWebServiceLocator();
locator.setMyWebServiceSoapEndpointAddress( "http://mywebserviceurl./axis/services/myWebServiceSoap" );
locator.setMaintainSession( true );
this.myWebService = locator.getMyWebServiceSoap();
The problem is that the locator above extends org.apache.axis.client.Service, however, the JSF generated client creates a javax.xml.rpc.Service object. I guess this might cause my problem.

Problem with ABAP Web service

Hello Experts,
Some unusual thing is happening.
Till this time my scenario was HTTP to RFC. So i have imported RFC in XI and its structure was perfact.
Tables having cardinality as 1...1, and fields were having cardinalities as 0....1.
Now we have planned to switch to the proxies and ABAP Web services. I have created the ABAP Web service with the same function module and imported it into the External definations.
When i am trying to use it into the mapping, Table cardinalities are 1....1 and fields are also having cardinalities as 1...1.
Now because of that i hv to map all the fields with some constants, but m not comfortable with it as there are nearly 1000 fields.
Do anyone of you have any idea what might be the problem? or how can i solve it.
Hope the question is clear.
Please help in this problem.
Thanks,
Hetal

Hello Hetal,
This is happening because when you genarte the Webservice out of a Function Module, all the fields in your are mendatory in the generated WSDL.
This can be avoided. The WSDL that you have generated for your webservice, can be manually edited in Stylus studio etc to change the cardinality and make it optional. We also did the same in one of our scenario and it is working fine.
As you are mapping these fields with constants, so it doen't make a difference if those are optional too.
Just edit the WSDL/xsd and reimport it.
Thanks

Can you all please let me know is the problem with model creatuion or Web Service configuration.
Thanks,
Archana.

It seams that the component 'tc/wd/wslib' is not well deployed on your server. You should redeploy it on your server.
-Go to nwds, Development infrastructure perspective
-Expand the FRAMEWORK item, there is the 'tc/wd/wslib' normally
Deploy :
-Open the menu Window > Show view > Other and open the Undeploy View
-In the undeploy view expand the FRAMWORK item and locate the tcwdwslib (it ther is no such application, then go directly to deploy steps after)
-Add the to the undeploy list (+ button)
-Click undeploy (blue button near + button
When it is undeployed, you can redploy it:
-In the Componenet Browser, locate the 'tc/wd/wslib' in the FRAMWORK as befor
-Right-click and click Deploy and click OK
If it not working, try the same (undeploy/dredploy) with 'tc/wd/wslib/api'
Check also that the dependencies of your project should have 'tc/wd/wslib/api' and not tc/wd/wslib/
Hope it will help you

Problems with OC4J Web services and Flex SOAPEncoder

Hello!
I got a problem trying to execute a web service running in
Oracle OC4j 10.1.3.3, and a client side with Flex3. I generated the
scripts for using the web service using Flex builder 3, but it's
not making a valid call to web service. I debugged the call
operation to the Flex SOAPEncoder which seems to generate an
invalid soap message. The SOAPEncoder generates the following
message;
<SOAP-ENV:Envelope xmlns:SOAP-ENV="
http://schemas.xmlsoap.org/soap/envelope/"
xmlns="
http://www.w3.org/2001/XMLSchema"
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<tns:getDocuments xmlns:tns="
http://modultek.atonpdm.document/">
<tns:getDocuments>
<tns:String_1>service manual</tns:String_1>
</tns:getDocuments>
</tns:getDocuments>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Where the correct working soap message should be;
<SOAP-ENV:Envelope xmlns:SOAP-ENV="
http://schemas.xmlsoap.org/soap/envelope/"
xmlns="
http://www.w3.org/2001/XMLSchema"
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance">
<SOAP-ENV:Body>
<tns:getDocuments xmlns:tns="
http://modultek.atonpdm.document/">
<tns:String_1>service manaual</tns:String_1>
</tns:getDocuments>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Problem in the first message is that Flex SOAPEncoder
generates an extra <tns:getDocuments> child tag, and Oracle
app server can't handle it.
Has someone any idea why SOAPEncoder is generating the extra
operation tag, and is this behaviour configurable somehow or is the
soapencoder broken?

Best regards, Janne

I am having the exact same problem. The SOAPEncoder is adding
an additional tag and the server thinks the envelope is not
properly formatted and therefore does not know what to do with it.
Is there any fix for this yet? Or has it even been reported as a
bug?

the code for my application is very simple and

when I try to consume this in my flex application I keep
getting the following error:

Any advice anyone could give would be wonderful. I'm pretty
new at this flex stuff but I feel like the problem may be with my
WSDL?

perhaps you missed this step:
--> Modify the code and add Credentials before calling the web method:
Public
SubMain()
Dim
ws As NewService1
ws.Credentials =
New System.Net.NetworkCredential("user name",
"password",
"domain name")
MsgBox("Square
of 2 = "& ws.Square(2))
Dts.TaskResult = Dts.Results.Success
End

Problem with OBIEE Web Service getHTMLForReport() Method

Hello, I´m trying to develop an example using the OBIEE Web Services and I have a problem with the method “getHTMLForReport(String pageID,String pageReportID,String sessionID)” (http://download.oracle.com/docs/cd/E12103_01/books/AnyWebServ/AnyWebServ_Methods8.html).
The problem is the next one: In the pageReportID parameter should contain a character string ID returned by the addReportToPage() method, but the addReportToPageMethod is a void method. (http://download.oracle.com/docs/cd/E12103_01/books/AnyWebServ/AnyWebServ_Methods4.html#wp1008810)
Which is the value of the pageReportID parameter?
Thank you.

Yes, there seems to be a bug in the oracle documentation. Basically, the second parameter of the addReportToPage() method is a free text. You can put "report101" as value of second parameter. Then you have to use the same string in the getHTMLForReport()method.
For example ..
addReportToPage(pageId, "report2", reportRef, "Jaggi Di Report", null, null, sessionID);
getHtmlForReport(pageId, "report2", sessionID);

Problem with Google Web-Service Example

Hi guys,
i have a problem with the Google Web-Service Example.
I am running EP6.0 SP9 and NWDVST 2.0.9
I did everything according to the tutorial. Got my google license key too.
When i test the web-service i get the following exception:

Problems with creating web service system

Hello,
I seem to have made some changes that made my unable to create web service systems for EP or Visual Composer.
The change I made is in NetWeaver Administration > Configuration > Application Resources > WebServicesFactory, I added the Configuration Property "UseCacheByDefault" with Boolean value = true.
After this, if I create a web service system in Enterprise Portal, the Connection Tests fail. In Visual Composer when I define a web service system, the error I am getting is: "Connector Factory not found for value WebServicesFactory".
I have tried to delete the UseCacheByDefault property I added as well as restart the server but I am still getting the error.
However when I test my web service using the Web Services Navigator, I am not getting any problems. So my guess is the problem lies with the connection factory.
Can anyone help me with this issue?
Thanks.

Hello,
Since creating WS system in the portal resulted with failed connection test, the issue has nothing to do with VC.
I'm just guessing, but try to configure proxy in the J2EE engine.
If that doesn't help I suggest you raise this question in the portal forum.
Best regards,
Shay

Problems with building web services - tutorial doesn't work

I've been going through this tutorial from technet.oracle.com -
trying to deploy the example stateless session bean service.
First problem comes when running the deploy command -
java -jar <j2ee_home>/admin.jar ormi://<host> <uid> <pwd> -deploy -file ejbws.ear -deploymentName ejbws.
This command fails insisting that it can't find application.xml (even though it is clearly in the .ear file).
Got around this by manually editing the server.xml file and bouncing OC4J. Then did the bind command. The first steps of compiling and running the client application then worked fine - I could see the .wsdl file and download the proxy jar.
But when I came to actually run the client I got the error:
Exception in thread "main" [SOAPException: faultCode=SOAP-ENV:Protocol; msg=Unsu
pported response content type "text/html", must be: "text/xml". Response was:
<HTML><HEAD><TITLE>500 Internal Server Error</TITLE></HEAD><BODY><H1>500 Internal Server Error</H1><PRE>oracle.j2ee.xanadu.JasperGenerationError: no source generated during code generation!: error: I/O error in UrlBridge to: file:E:\ORACLE\j2ee\home\application-deployments\ejbws\ejbws\temp\__session_bean_rpc\Hello.class.<br>binary class definition not found: Hello
By manually copying the Hello.class file into the __session_bean_rpc directory I was able to get the example to run.
But how do I get it do deploy correctly in the first place????

I ran into the EXACT same problem described by Tracy, and I assembled my .ear file manually.
According the error message, it would appear that the server is looking for the EJB remote interface in the ../temp/__session_bean_rpc directory when it is trying to generate its session bean wrapper class. As Tracy notes, when the file Hello.class is copied into the directory, the problem goes away. Furthermore, once the wrapper class has been generated, Hello.class is no longer needed and can be deleted from the directory.
Better still, I found a way to deploy the web services web module and make the error go away. I created the ejbws.war file with a copy of the remote interface Hello.class in the WEB-INF/classes directory. This makes the class available when the wrapper class is generated.
The WebServicesAssembler tool doesn't copy the EJB remote interfaces into the .war web module, which would appear to be
necessary.
Hope this helps.
