Question - Putting a Face on Web Services and SOA

Hi,
I have attempted to use the example (http://java.sys-con.com/read/192427.htm)with JDeveloper 10.1.3, and I keep running into the same error when I compile the
BPEL, it complains regarding the "soc_security" global variable - "make sure variable with messageType definition is used" this is just a local variable to pass
a value around?
Any comments/suggestions regarding how I can fix this issue would be most appreciated.
Details from JDeveloper below.
Error(84):
[Error ORABPEL-10032]: missing messageType
[Description]: in line 84 of "C:\002_DEV\loanMark1\loanMark1\bpel\loanMark1.bpel",

[Potential fix]: make sure variable with messageType definition is used in incoming
and outgoing activities.

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

Web services and security

hi, i've successfully programmed a labview webservice and its all working fine, but im using a computer with public IP, and i can access to this webservice just typing the adress like in the webservices examples. my question is how can i create an authentication in a way that only the person with credentials can access his service? There are an easy way to have variables connected directtly connected to vi to verify the users before using the service?

Web services and e print not working on 7520e

After the update it instructed me to turn off my printer so the update could take effect which I did but my printer would not turn back on. leaving it overnight it was the same the next day so I had to unplug it from the wall outlet. I lost my internet connection and no matter what I did I could not get it to connect.I called cloud services who put in a network address of 192.168.223.1 and hung up leaving me with no printer and sending me an email to get my ISP server to fix.
I called HP support and they got it connected just fine but when I try to log into my printers web page it still has my
hp email address but when I try to get to the web page it leads me to Launch HP network check.
on the front of my printer it says unable to connect to the internet, enter a proxy address, my server does not use one.
I tried to disable web services and then enabled them again hoping to get a new code but no luck. In my own network it has the last digit different to the one being used and set as a static IP address . I was not able to scroll any Apps before any of this happened, is the server down or has anyone any ideas how to fix this. has anyone else got the same problem. The schedulled Apps printed off just fine before this.

Hello dylon,
Thank you for being an active member of the HP support community. I understand that your Photosmart 7520 printer is indicating that it is not connected since doing a firmware update last week.
Please start by setting a manual IP address and manual DNS servers. Please use this post with the steps and screen shots on how to do this. The screen shots are for the Photosmart 7510 but the steps are the same.
If you find that you are still unable to connect to web services please call HP’s Cloud Services at 1-855-785-2777 if you live in the USA/Canada region. If you live outside the USA/Canada region please click here to find the Technical Support number for your country/region.

Java app with web service and servlets

Hi. I intend to make a java application which exposes some methods as a web service and as jsp/servlets. It's core functionality is not really web centric, but its more a java app with a web tier. I am not sure about how the architecture of such a system would look like using the java platform. I currently see three options:
1. Run everything in a servlet container like tomcat. I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web services. However, it would be really easy just to put everything into tomcat and use ServletContext to maintain some global objects.
2. Use a Java EE to seperate application/business logic and data access into session beans and entity beans. I hesitate to this because it seem a bit overkill because the system isn't very big or complex right now. It also means that I would have to learn to use EJB's instead of just using some POJOs.
3. Run the web tier in a servlet container and the main app in a separate JVM, and then connect the tier by sending serialized objects over TCP sockets. I don't like writing network code but at least there is some separation of the tiers.
What would you do? Maybe I have overlooked a much better solution to the problem?
Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) instead of the something quick and dirty that is hard to defend.

Let me just say that the system is the product of a student project spanning one semester, so it's important to choose the RIGHT solution (architectural-wise) That pretty much makes it impossible then.
1. A "Right" solution is generally only proven by time.
2. It requires a great deal of knowledge about the business domain.Yeah, you are right. Let be try to rephrase it. What solution (pattern) would be considered the most common or appropriate when you have a Java App and want to expose a few methods as a website and web service?
I hesitate to do this because i would be putting a lot of functionality which isn't about the web into a servlet container. Also, I have a lot of application scope data that is maintained and shared by all servlets/web servicesHuh? Do you already have an exposed web service? If you already have a server which other clients communicate then where does this functionality that you don't want to be tomcat running now? Or where do you think that you want to run it? And if you are or do run it somewhere else then tomcat could access it the same way any other client accesses that server.Sorry, that sentence was written badly. I don't have anything right now. What I meant to write was that I will have a lot of application scope data, objects that are kept in memory as long as the server is running, shared by multiple servlet instances.

Deploying a VB dll using some web service and accessing it through java

I'm new to Web Services Based Programming. I would like to know whether this is possible and if so has anyone tried it. I want to create a vb dll that contains the remote methods that the client will access from a java program. After going thru a lot of articles, I'm still unsure on how to do this. I found one method was to Create a VB program/dll, deploy it in a web service and create the java program that accesses by another web service.
I'm doing this as part of my lab syllabus. The thing is My lab exercises do not state anything about the technologies that I can use to do this.
This is all that is stated there:-
Creation Of DLL Using VB And Deploy it in Java
I just cant get any ideas other than deploying both the parts as web services. If anyone has Better ideas for this, I would really appreciate it.
I dont know anything about CORBA for languages other than Java and I'm already using the servlets and EJB's in my normal life. I'm also learning the ORB based programming in java. Therefore your help will probably help me learn something new then what I know.

Sorry I wasn't too specific in my last question.
This is my java class calling the native method print
//HeyWorld.java
class HeyWorld {
private native void print();
public static void main(String[] args) {
new HeyWorld().print();
static {
System.loadLibrary("HeyWorld");
In this case, my C method for calling a C++ method: HelloWorld.cpp
#include "jni.h"
#include "stdio.h"
#include "stdafx.h"
#Include "HeyWorld.h" //this is where i get my function prototype
#include "Test.h" //this is the C++ header where the print method and the Test class is
JNIEXPORT void JNICALL
Java_HeyWorld_print(JNIEnv *env, jobject obj)
CTest a; //CTest is the print class I created
a.print();
//This is the header for Test.h
class CTest: public CWinApp
public:
 CTest(); //constructor
 void print(); //our method
//And this is the implementation of the class Test.cpp
void CTest::print()
 printf("Hey World!\n");
 return ;
I could compile the Test.cpp, HeyWorld.cpp successfully. However when I tried to compile HeyWorld.cpp using
cl -I<path of jdk include> -I<path of jdk include win32> -LD HeyWorld.cpp -FeHeyWorld.dll,
the VC++ 6.0 compiler gave me this error:
HeyWorld.obj:error LNK2001: unresolved external symbol "public:_thiscall CTest::CTest(void)"
HeyWorld.obj:error LNK2001: unresolved external symbol "public:_thiscall CTest::print(void)"
Thanks for the help.

Web Services and JHS

My company is exploring the use of JHeadstart and we are very impressed with its capabilities. The enterprise environment into which our system will be deployed requires separation between the View Layer, and the Model Layer, with a SOAP-based messaging agent as the go-between (it's MQ series-based). We have been able to get a prototype plain-old UIX application to work where we deploy the Application Module in the Model project as a web service, and then create a data control from the stub to consume in the UIX ViewController project. We can then simply drag and drop the Web Service call result sets onto the UIX pages. However, when trying to do this with JHeadstart, the Wizard for creating Application Structure Files requests an Application Module on one of the first screens. In our environment, we won't be able to allow the ViewController project to see the Model project. Is there any way to use a web service instead of the Application Module? If not, is there any plan to support this type of activity in a future JHS release?
Thanks in advance,
Dan Schiff

Dan,
Currently JHeadstart only supports ADF Business Components as the Business Service layer (directly accessed, not through a Web Service wrapper). As you found out, ADF supports other Business Services as well, not only Web Services but also TopLink, EJB, etc.
JHeadstart is primarily intended for data manipulation (select, insert, update, delete) and our philosophy is that that type of functionality (that part of your application) is most efficiently handled directly by ADF Business Components. Also, this is the most productive technique for application developers. Of course, the end result of generating an application with JHeadstart is that you have a "normal" ADF application, to which you can add Web Service functionality with the normal JDeveloper visual editors and drag-and-drop features.
So you could generate efficient data manipulation screens using JHeadstart and direct ADF Business Components, and then add interoperability with other Business Services to your application using Web Services. The latter part is not JHeadstart-generated.
The next JHeadstart release (10.1.3) will be focused on supporting JSF (JavaServer Faces). We are also looking into support for other Business Services like TopLink, but we don't have any schedule for that yet.
kind regards,

Interfacing web services and RT applications

[First, sorry to the NI guys who helped me with this over the phone. It's not that I don't trust your input but in the multitude of counselors there is wisdom.]
If I want to interface my cRIO real-time control loop with the outside world using web services, how do you implement the interface between the web service and the RT app? If the RT app is included as part of the web service, will it start running at target boot time or must it be invoked using the web service?

Aaron--
What I have now is a web service only application--I only have one Build Specification and it is for the RESTful web service. I placed what typically would be my RT application code in the web service Source Files section without any URL mappings to go with it. Then I simply call the top level RT executable code from the web service by static reference and have it return without waiting for code execution to complete. At this point, my "RT app" is running on the cRIO and can communicate with the web service via functional globals.
The fact that my "RT app" does not run at boot time is not an issue in this application so I feel like I'm getting by on a special case. If I needed to run the RT application at boot time with headless operation, I think I would still be having a problem. I just find it a bit quirky that NI's web services put the developer in the situation that, in order to communicate with an RT executable, they must use shared variables (yuck) or implement a mini virtual network. Why not put the web service and the RT app into the same application space and be done with it?
Thanks,

Siebel OnDemand Web Services and BPEL II

We are trying to do a POC for a given client that is trying to decide between SOD and another on demand CRM product.
Our POC is to integrate SOD using bpel and sending data to a back end system with SOD as the originator and instigator of the flow.
We intend to take data from an integration event pull it into bpel do a transformation to add data to it and update SOD to complete the circuit.
We are having a few issues and was wondering if you can provide some insight since we would like to put SOD at this site.
Our issues are :)
Issue 1
When we import the WSDL for the Integration event the scheema's are not resolved.
Issue 2. When we import more than one WSDL in our flow it has issues with duplicates between the 2 wsdls..
issue 3.
We have succesfully used the example application to do our login and faked out the endpoint but have not been able to automate this step.
We found an example online at oracle ( http://www.oracle.com/technology/tech/fmw4apps/siebel/ofm-siebel-blog-postings.html)
(We got that link from the other BPEL post: Siebel OnDemand Web Services and BPEL
But when we copy the code into our embeded java object it doesn't work. I think that we may be missing some of the code to use.
Do we have the full copy of this java object?
here is hte error that we get from bpel
Exception reported is: Siebel_On_Demand.bpel:33: Class bpel.p0.URL not found.

I'm also trying to do this.
Some info from the Siebel web services guide:-
"The login request is an HTTPS request to instantiate a session and obtain a session ID. A client invokes login by sending an HTTP GET request to a URL like the following:
https://secure.crmondemand.com/Services/Integration?command=login
NOTE: The login parameter value is case sensitive.
■ Login input. The input to login is provided in the URL parameters and the HTTP headers, as follows:
■ The only URL parameter to be set is command. This parameter value is login.
Two HTTP headers, UserName and Password, must be set with the appropriate values for your system. For example:
❏ UserName: [email protected]
❏ Password: mypass
■ Login output. The login command returns the following items:
■ A session cookie, jsessionid. The client must use this cookie when submitting subsequent requests, including logoff requests.
■ A status code of 200, if the session does not encounter any errors. This indicates that the request succeeded.
Then to get data out ....
Integration request input. The jsessionid returned to the client during login must be included with the request. The request must contain the jsessionid either as a cookie or as a URL parameter, as follows:
https://secure.crmondemand.com/Services/Integration/object;jsessionid=xyZ12489w3482413
Does anyone have any ideas on how we might do this using the Oracle BPEL PM?
Thanks in advance.

Simple question re invoking non-WebLogic web services

I have a very simple question that I haven't been able to resolve elsewhere.
I need to invoke 3rd-party SOAP interfaces from my WebLogic 6.1 client EJB. All
the Bea documentation I've found refers to invoking "WebLogic Web Services" and
speaks of downloading the client.jar -- however, in my case it's not a "WebLogic
Web Service" I'm invoking, it's a non-WebLogic web service.
Does WebLogic 6.1's WebServiceProxy (or other tool) allow this? Or must I use
some other SOAP tool such as Apache Axis in this case?
Thanks.
Cheers,
allan

Could this interopability problem have something to do with a problem
I'm experiencing on 61.sp3?
I have an EJB that accesses SOAP services on a Tomcat server. The SOAP
service sends back a SOAP exception which is correct in what I am asking
in to do. However, the weblogic app server is returning a SOAP
exception to my EJB rather than passing the SOAP exception to the API
that I am using to make my SOAP calls.
Has anyone seen something like this?

use that code within your EJB.
The javadocs for the WebServiceProxy class (from BEA's site)
will give you more methods that may be useful to you.
Note that your best bet, if possible, is to use the JAX-RPC
APIs within WebLogic 7. The SOAP support in WL6.1 has
interoperability issues.

The only way I know is to use digital wartermarking and
tracking
services like DigiMarc as suggested by Bregent in your
previous thread.
It's kind of neat in that it places digital information in
the images
as noise. In most cases it's quite unobtrusive, but only you
can be the
judge of that.
The information even survives through some minor editing of
the files.
So if somebody crops your visible watermark or does some
other minor
editing, the information is still in the file.
I'm only an amateur photographer and my free trial ran out
years ago. I
did not get to see the tracking system in action with the
trial
version.
