$25 Reward - Calling a CFC via Remote Object or Web Service without making the result public

I am just getting into Flex 2, so please forgive me for my
newbe vocab.
Here is how my applications have worked in the past, i.e.
ColdFusion:
<cfscript>
//Create an instance of component
order = CreateObject( 'component', 'PEK.Catalog.Order' );
//Call methd
theOrder = order.getOrder(1234);
</cfscript>
Display the order via HTML and CFML.
getOrder() returns a query and 1234 is a sample orderID. The
most important part of the solution I am looking for is that the it
must not expose my getOrder() as a public web service. I am able to
run the application with WS by making the mothod URL visible and
remote, but this is no way near the security I would like to have.
Here is my folder structure where components folder has been maped
to CF.
Application
|__extentions
| ... |__components
| ... ... |__PEK
|__wwwroot
I guest there should be a way to call CFC with the thing
remote object that I have no idea how to set up. So please what
would be a solution to my security issues.
Thank you in advance!

I guess this article answers part of the question. It is very
important to note that if the CFC is sitting on the same server as
the CFC the component methods could be public and not remote, thus
making it alot more secure.

RMI and Threads: Calling wait() on a remote object

I created a counter as a remote object.
Multiple clients are displaying the counter value.
If one of the clients increments the counter, I want the displayed counter value on every client to be updated to the new value (of the counter on the server).
Therefore every client starts a new thread to "listen" for changes of the countervalue. I wanted to call the wait() method on the remote object (the remote counter). But i think it will be called on the stub instead of on the actual remote object.
Therefore i created a extra method waitForChange() on the remote object.
public void waitForChange() throws RemoteException, InterruptedException {
     synchronized(this) {
          wait();
This method only calls the wait() method. Now I'm sure it's called on the remote object and not on the stub.
This works, but my question is: is there a better way to do this?

}This is just a little test. Actually I want to notify clients of changes in data displayed in a Table. If one client saves one record of the data, i want the new record to be displayed immediatly on all clients that are viewing the same data.

I've been doing some reading about RMI and callback.
As I understand it, there's a remote object is running on the client now as wel. And the server makes a call to the client.
But now the server makes a call to one client.
And the point is, I want all clients to be updated with the new value.
Does this mean, I have to keep a list with references to all clients connected to the server?
I my code the notifyAll() method causes all waiting Threads (running on several clients) to wake up and do something (getting the new counter value).

I guess, this is because the RI client is not finding the
codec to ser/deser your Value Object. You need to register
the codec in the type mapping registry before you invoke
the web service method.
Here is a sample:
Service service = factory.createService( serviceName );
TypeMappingRegistry registry = service.getTypeMappingRegistry();
TypeMapping mapping = registry.getTypeMapping(
SOAPConstants.URI_NS_SOAP_ENCODING );
mapping.register( SOAPStruct.class,
new QName( "http://soapinterop.org/xsd", "SOAPStruct" ),
new SOAPStructCodec(),
new SOAPStructCodec() );
BTW, you can do the same exact thing on the client by using
WLS impl of JAX-RPC. Is there a reason for using RI on the
client side?

Hi Manoj,
Thanks for your information, Yes, my client is Sun's JAX-RPC based, but the Server

It works fine without any problem. But when I invoke the webservice using WSDL,
I am getting this problem.

How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file?

How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?

Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.
Follow MSDN-
http://msdn.microsoft.com/en-us/library/ee377035%28BTS.10%29.aspx
http://msdn.microsoft.com/en-us/library/system.servicemodel.description.servicethrottlingbehavior.maxconcurrentcalls.aspx
I hope this helps.

Could not generate stub objects for web service invocation in ColdFusion

I was able to call the services on the development box - windows server without any problem at all, everything was working fine but the moment i uploaded to a linux box production server I get this error. "Could not generate stub objects for web service invocation in ColdFusion"
What could be the cause of this problem, i have googled a lot but no solution yet any ideas.

Let me make it simple:
1. Server A is our development server.- hosted inhouse with coldfusion installed.
2. Server B is our production server - a linux server with coldfusion installed hosted on the internet
3. Server C is a third party server containing the webservice - this is a windows server with .net
coldfusion is installed on Server A, the code works here and can connect to server C without any problem. It gets the required respone
but when the code was uploaded to server c it gives the error when we run it.
now i tried just a simple code which works fine on server A below:
<cfinvoke webservice="http://www.webservicex.net/CurrencyConvertor.asmx?WSDL" method="ConversionRate" returnvariable="ConversionRateResult">
    <cfinvokeargument name="FromCurrency" value="EUR" />
    <cfinvokeargument name="ToCurrency" value="USD" />
</cfinvoke>
<cfdump var="#ConversionRateResult#" />
But when i uploaded it to server C: it returns the error
Cannot generate stub objects for web service invocation.
Name: http://www.webservicex.net/CurrencyConvertor.asmx?WSDL. WSDL: http://www.webservicex.net/CurrencyConvertor.asmx?WSDL. java.io.FileNotFoundException: /opt/coldfusion8/stubs/WS728929035/NET/webserviceX/www/Currency.java (No such file or directory) It is recommended that you use a web browser to retrieve and examine the requested WSDL document to ensure it is correct. If the requested WSDL document cannot be retrieved or is dynamically generated, it is likely that the target web service has programming errors.
The error occurred in /home/works/public_html/currency.cfm: line 7
5 :     <cfinvokeargument name="FromCurrency" value="EUR" />
6 :
7 :     <cfinvokeargument name="ToCurrency" value="USD" />
8 :
9 : </cfinvoke>
Now if you try the preceeding code on a windows environment it works fine but the moment you put in the in the linux environment it generates this error
I feel that the error may actually be :
java.io.FileNotFoundException: /opt/coldfusion8/stubs/WS728929035/NET/webserviceX/www/Currency.java (No such file or directory)
but i am clueless as to what to do next
Ok so I tried the wget command on the linux
this is what i got
-bash-3.2# wget http://www.webservicesx.net/CurrencyConvertor.asmx?WDSL

Create a virtual classroom via Adobe Connect 9 Web Services

Is it possible to create a virtual classroom via Adobe Connect 9 Web Services? I could not find a way in "Using Adobe Connect 9 Web Services" documentation.

The answer of Jorma Jenning is almost correct. I investigated it myself and finally made a working solution.
The trick is that virtual classroom does not have a special type, instead it is a "meeting inside trainings folder with the icon of virtual-classroom". Kinda strange logic and to add another level of hell the "trainings folder" is the one with the type "my-courses", so, finally, we get the the following workflow:
1. Call h-ttps://example.com/api/xml?action=sco-shortcuts and filter sco-s until you find one with the type="my-courses" and remember its sco-id — this will be your folder-id.
2. call h-ttps://example.com/api/xml?action=sco-update&type=meeting&icon=virtual-classroom&name=October All Hands Meeting
&folder-id=2006258750&date-begin=2006-10-01T09:00
&date-end=2006-10-01T17:00&url-path=october
The thing with icon is important.
Note that if you call report-my-training service immediately after sco-update you won't see this virtual-classroom. This is because the default permissions do not allow that. Add yourself to the user list via permissions-update and it will appear in your training list. This is different from creating virtual classroom from web interface as there you are added as a host by default.

Call function in background task... How to get the result?

I want to use Call function in background task parameter.
But I cannot find the result of this function. (No export parameter, no table result, no exception)
How to get the result of this function module? Correct or not?

Hi Heinz,
You can check the result in SM58 transaction.
For more information pls. refer this thread :

Java.lang.NullPointerException while creating virtual classroom via Adobe Connect 9 Web Services

Hello all, I am trying to create a virtual classroom via Adobe Connect 9 Web Services with the code below.
https://XXXXXXXX.adobeconnect.com/api/xml?action=sco-update&type=virtual-classroom&name=My Virtual Classroom&folder-id=1358451232&date-begin=2014-01-02T10:00&date-end=2014-01-02T11:00
And the result below:
<results>
<status code="internal-error">
<exception>java.lang.NullPointerException</exception>
</status>
</results>
What could be the reason of this problem? I need your help.

Hi Teomanx
To create a virtual classroom, you have to give type=meeting & icon = virtual-classroom. So the correct syntax is :
https://XXXXXXXX.adobeconnect.com/api/xml?action=sco-update&type=meeting&icon=virtual-clas sroom&name=My Virtual Classroom&folder-id=1358451232&date-begin=2014-01-02T10:00&date-end=2 014-01-02T11:00.
Hope that helps.
Thank you

How to call Axis 2.0 web service without wsdl

Hi,
Is it possible that I can call Axis 2.0 asynchronous web service in orabpel without wsdl.? As Axis 2.0 is not generating wsdl file.
Regds,
Farooq

A Web Service without a WSDL describing it??? Seems like a contradiction to me...
Are you 100% sure about this? I am not an Axis expert, but this sounds strange.

I'm not sure what are you asking for. If you are looking to create a data-control based on a web service then this online demo might help:

Calling a java class from a java web service

I have deployed a web service to weblogic 8.1 SP5 and now i want to call a simple java class from that web service.How can i do it.

Hi jazz123,
There's an example in the [*Java Web Services Tutorial*|http://java.sun.com/webservices/docs/2.0/tutorial/doc/] : see Chapter 1: Building Web Services with JAX-WS - A Simple JAX-WS Client.

Flex and CFC with Remote Object

I wrote a simple cold fusion componenet on my webserver at:
http://www.paramountmediainc.com/webservices/eadexchange/agent_sys.cfc
Now I want to play with that in Flex with a Remote Object.
I'm writing the flex on my local machine. I tried this approach but
was uncessfull:
<mx:RemoteObject id="acctRO" showBusyCursor="true"
source="webservices.eadexchange.agent_sys"
endpoint="
http://www.paramountmediainc.com/flashservices/gateway">
I get the following error ...
TypeError: Error #1034: Type Coercion failed: cannot convert
Object@3b15da1 to mx.messaging.messages.ErrorMessage.
Any ideas what I'm doing wrong here?

You cant really replace Struts with Flex, maybe a view part
, thats about is, you still need backend processioning
logic,all that you are asking is difficult to answer is one reply,
IMHO, best thing you can do is to dive into following URLs :
http://www.adobe.com/devnet/flex/
http://livedocs.adobe.com/flex/3/html/help.html?content=Part2_DevApps_1.html
http://livedocs.adobe.com/blazeds/1/blazeds_devguide/

Using authorisation object in web services

HI ,
I create a WS proxy via ESR and I want to avoid malicious attack ,
do i need to use the Following authorization object ?
AUTHORITY-CHECK OBJECT 'S_ICF'
ID 'ICF_FIELD' FIELD 'PROXY'
ID 'ICF_VALUE' FIELD 'PROXY_NAME'.
Regards
James
Edited by: James Herb on Feb 25, 2010 9:45 AM

S_ICF is to protect the SAP auth. group of the proxy itself from being called (and an impact on admin access in SICF as well), but with ESR you will most likely have to give that to all your users and still you don't know which service they are consuming. So... use S_SERVICE.
As the name of such a URL generally exceeds the length of an authorization field... S_SERVICE uses a "hash" to represent it. Executing the service will generate the hash.
The easy way to collect them is via an ST01 trace on each application server and maintain SU24 manually.
The Rolls-Royce way to collect them is via the "original data" trace of SU22, then process the results carefully in SU25 step 2b... thereby maintaining SU24. Take a closer look at the posts by SAP security guru Frank Buchholz in the thread Secure custom developer programs and transactions for more details.
I assume that you are a developer so if you have not used this before and what I have described above makes only limited sense for you, then I suggest talking to the security person on site to show it to you or going to a training on it the first time.
Anyway, if the checks are "native" in the system, then this is a security job so find the person building the roles for the services. Most likely they are already ontop of this and will take care of it for you.
Cheers,
Julius

Calling helper class that refrence to WCF web service

Hi I have a BizTalk projects that calls a helper class. now the helper class receive the message and a counter and is suppose via the class to create a login to a WCF
web service and then synchronize the message to this WCF web service.<o:p></o:p>
this is class:<o:p></o:p>
public static string SyncConcerto(XLANGMessage msg, int count)
SelectResponse select = (SelectResponse)msg[0].RetrieveAs(typeof(SelectResponse));
ConcertoService.ExternalMappingServiceClient concertoServ = new ConcertoService.ExternalMappingServiceClient();
ConcertoService.ExternalMappingItem extMapItem = new ConcertoService.ExternalMappingItem();
ConcertoService.ExternalMappingServiceResponse extLogonResp = new ConcertoService.ExternalMappingServiceResponse();
ConcertoService.ExternalMappingServiceResponse extSyncResp = new ConcertoService.ExternalMappingServiceResponse();
extLogonResp = concertoServ.Logon("*****", "******", true);
if (extLogonResp.StatusCode == 1)
if (count>0)
for (int i = 0; i < count; i++)
extMapItem.Attribute1 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.REGION_NAME;
extMapItem.Attribute2 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PROJECT_NUMBER;
extMapItem.Attribute3 = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PRODUCT_NAME;
extMapItem.ProjectName = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PROJECT_NAME;
extMapItem.ProjectMgr = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.PM_NAME;
//extMapItem.ProjectMgr = select.SelectResult.CNS_CONCERTO_PROJECTSRECORDSELECT.PM_NAME;
extMapItem.Division = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.DIVISION_NAME;
extMapItem.Subject = select.SelectResult[i].CNS_CONCERTO_PROJECTSRECORDSELECT.CUSTOMER_NAME;
extMapItemArr[i] = extMapItem;
extSyncResp = concertoServ.SynchronizeExternalAttributeData(extMapItemArr);
if (extSyncResp.StatusCode == 1)
return "sync success login success";
else
return "success login sync faild";
else if (extLogonResp.StatusCode == 2)
return "TimeOut";
return "Failed";
Now it keeps throwing exception in this line of code: ConcertoService.ExternalMappingServiceClient concertoServ = new ConcertoService.ExternalMappingServiceClient();
saying he needs a valid endpoint. but he has the app.config file already that stats his endpoint.
What am I doing wrong, since I have never done a thing like that before.
And also I can't use the WCF web service in the normal BIZTALK way due to login operation he needs to do. <o:p></o:p>
Any advice on how to continue?<o:p></o:p>

the WCF has a logon operation where I enter a user name and password, it doesn't return a session key meaning I can't send a message to the WCF WS (Biztalk is stateless) that doe's the logon operation and the synchronize operation. so I had to do it with
the helper class.
and Morten I know this is very bad practice but I don't have choice for now.
Morten another question since we are using Biztalk 2013 (New Enviroment) our BTSNTSvc.exe.config is empty:
<?xml version="1.0" ?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" />
</startup>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<probing privatePath="BizTalk Assemblies;Developer Tools;Tracking;Tracking\interop" />
</assemblyBinding>
</runtime>
<system.runtime.remoting>
<channelSinkProviders>
<serverProviders>
<provider id="sspi" type="Microsoft.BizTalk.XLANGs.BTXEngine.SecurityServerChannelSinkProvider,Microsoft.XLANGs.BizTalk.Engine" securityPackage="ntlm" authenticationLevel="packetPrivacy" />
</serverProviders>
</channelSinkProviders>
<application>
<channels>
<channel ref="tcp" port="0" name="">
<serverProviders>
<provider ref="sspi" />
<formatter ref="binary" typeFilterLevel="Full"/>
</serverProviders>
</channel>
</channels>
</application>
</system.runtime.remoting>
</configuration>
where do I insert my end point and how?
