Get client ip address from Web Service hosted on OAS 10.1.2

Hi,
Can anyone advice how to get the client IP from a web service (java) hosted on Oracle Application Server 10.1.2.
The below code works if the web service is hosted on Tomcat.
MessageContext msgCtxt = MessageContext.getCurrentMessageContext();
String IP = (String)msgCtxt.getProperty("REMOTE_ADDR");
This code is causes built errors on the OAS 10.1.2 since it needs Axis and many other Jars. I tried to insert the jars needed but unfortunately when i was able to compile it returned a java.lang.NullPointerException.
Is there a way to get the IP address of the client that calls this web service ?
Or is there a way to read the SOAP request maybe i can retrieve the client IP from it.
Thanks for your support,
regards

How to get client Ip address from web service

Hello folks,
I am quite new to web service and developing a web service using netbeans6.0 IDE, where i have to know which client called/used the service, After googling i got code snippet like below
inject a WebServiceContext instance into your WebService class, and use it in each WebMethod to get the current request's MessageContext Map. Get the SERVLET_REQUEST item from that, cast as an HttpServletRequest. From that HttpServletRequest, you can invoke getRemoteAddr() to get the client's IP.
@WebService
public class MyService{
@Resource
WebServiceContext wsCtxt;
@WebMethod
public void myWebMethod(){
MessageContext msgCtxt = wsCtxt.getMessageContext();
HttpServletRequest req = (HttpServletRequest)msgCtxt.get(MessageContext.SERVLET_REQUEST);
String clientIP = req.getRemoteAddr();
}But it throws error in my PC like
Service invocation threw an exception with message : null; Refer to the server log for more details
Exceptions details : java.lang.reflect.InvocationTargetExceptionIs there any way that says client pc ip address using netbeans6.0 Or what went wrong in my code?
Largely Thanks in advance.
SRI.

GET, Modify, POST XML from Web Service Requests (Webtests)

I'm using load testing to exercise an API, so I'm creating many small webtests which mimic typical user operations. One of my operations will be a GET of transaction data and a PUT of that same data, slightly modified.
I'm able to capture the response from the GET in an extraction rule and resubmit to the API, the question is how to manipulate the XML so that there's a small typical edit. What's the best way to do this?
I understand the nature of the web test plug-ins, as the "cartilage" around the bones of the webservice requests. I would much rather angle towards a plugin than convert to a coded test and modify that way. I like the normal non-coded
test interface but I dont know that the webtest plugin nor webtest request gives me the granularity the coded webtest does. Unfortunately, I dont like the fact I can't easily debug through the coded webtest.
This seems like a straightforward operation. Do I understand all my options? How would you do this?

On further review, I might have figured this out. I misunderstood something I read online. The web test request plug-ins can be associated with an individual service call and aren't automatically applied to all service calls in a web performance
test collection.
.. I can do something like this to access my captured context information and manipulate the XML via XDocument/XElement. - This demonstrates how to get my captured {{ResponseDocument}} from the extraction rule.
public class XmlModification : WebTestRequestPlugin
public override void PreRequest(object sender, PreRequestEventArgs e)
MessageBox.Show(e.WebTest.Context["ResponseDocument"].ToString());

Getting client IP address from PL/SQL Portal API

I'm doing a customized login portlet where I'll like to get access to the IP address (I order to restrict admin access to specific IP addresses).
Is that possible in the Portal API.

Hi,
Check this help.
http://help.sap.com/saphelp_nw2004s/helpdata/en/de/89023c59698908e10000000a11402f/frameset.htm
You'll see that there is a param wdisp/add_xforwardedfor_header
which
"The parameter determines whether the SAP Web dispatcher includes the IP address of the client in the header field x-forwarded-for. If it does, the application on the application server can read the route that the request has taken. If the parameter has the value false, the Web dispatcher leaves the header field unchanged."
Together with the forwarder field that I've mentioned earlier, this should achieve things you need.

Echo.java
EchoService.java
EchoService_Impl.java

I created a JSP portlet and the jsp content of it is-
String url = "http://localhost:8080/SOATest/services/Echo";
Echo echo = new EchoService_Impl(url).getEcho();
getNumsResponse = echo.getNums(getNums);

My web service is using soap binding. I have tested it with eclipse and other tools also. It is working well and good. But when I tried to call a web service which is created and hosted on WebLogic server(running on port : 7001), I got the correct output.
Can anyone help me out in calling a web service hosted on different server from WebLogic server.
Thanks in advance,
Tiijnar

Hi
1. The way you are invoking the WebService deployed on Tomcat server is looks suspicious. It may be valid by adding extra ?wsdl etc into the url, but still I have not seen this way to invoke the webservice.
2. So you used Weblogic ant task to generate client JARs by giving this WSDL. So looks like it generated the 4 classes (.java) and in addition any other classes for Request/Response xml objects.
3. Look at the source code of EchoService.java. It should have one default empty constructor. Internally it uses the default wsdl defined in this class. You will see another constructor that takes WSDL URL as one of the parameters (QName) etc. Echo.java is the class corresponding to the Port. In the same EchoService you should see an instance method like getEcho() something like that. This Echo.java class will have methods for all the Operations defined on this Port. So the standard code snippet we use most of the times will be like this:
EchoService myEchoService = new EchoService(); // Default it uses WSDL deployed on Tomcat at localhost:8080
Echo myEchoPort = myEchoService.getEchoPort(); // Something along these lines.
myEchoPort.xxxYYY(); // NOW this is the operation name that takes the input parameters and returns outputs defined as per the WSDL defintions. If the Input and Outputs are complex xml types, it will have corresponing .JAVA files with setters and getters.
Now if this WebService is deployed on same Tomcat but on different machine or different port, you just give the full WSDL URL with that host and port in the constructor for new EchoService(...). You may need to instantiate QName object. But look at the methods generated in EchoService.java class.
The way you are using with Impl and Stubs class may also work. I am not much famiiar with this APIs apporach. Still look at the methods generated in these classes.
Also if you latest Sun JDK 1.6, it also has one command like wsimport. Infact if you install WLS 10.3 with Sun JDK, it should have C:\beawlp103\jdk160_05\bin\wsimport command. This will also generate client jar given a WSDL URL.
Thanks

Is it possible to invoke external REST web service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4)

Is it possible to invoke an external REST web-service hosted in WebLogic web application from an Adobe LiveCycle Process (ES-4) with parameters as input and manipulating the response depending on the type of parameters it gets back. Then invoking an Adobe Form and prepopulating the Form based on the response parameters? Do you have sample projects that do this invocation. The part highlighted in red is what I need examples.

You can simply use "Execute Script" operation in Workbench and make use of java.net.URL. Below links should help :

How get data from Web Service with token?

Can I get data from Web Service made with Java?
This WS has a Token.
Any ideas o reference?

We've now added this ability to Web.Contents. You can say something like
Web.Contents("http://my.web.service/1", [Headers=[#"The-Token"="0a0138ef2d"]])
and it will pass a header with the key "The-Token" and the value "0a0138ef2d" as part of the HTTP request. For security reasons, this will only work for anonymous web requests.

Presence data from web service

Hello,
i like to get presence data from the presenceconsumer web service. But everytime a call getUserPresence i get a PolicyException (POL0002): 'Privacy verification failed for address %1, request is refused'.
I use a web service proxy generated from the wsdl of the presenceconsumer web service. Authentication is made against the appregationproxy by setting username and password. Both users (the one i use for authentication and the one whose presence data i want to get) are registered in the timesten database.
The user whose presence data should be accessed is logged in the OracleCommunicator and has the other user on the allowed list for presence data.
All other operations of the presence web services work without any problem, so why not getUserPresence?
Thanks for help

Hi,
I have found the problem and fixed it :)
If you see my code, I was checking for the pending subscriptions after publish() method. When I tried this check before publish() method, I got the expected results (All the pending subscriptions).
Also, I got an error (ServiceException) while dynamically retrieving the subscribed attributes for some reason. I have found an alternative solution, by manually allowing only the PresenceAttributeType.Activity (instead of all getSubscribedAttributes()).
Note: This code was working fine in my local machine because, I have already setup-ed the users (Buddy list) through Oracle communicator in my machine. I was not able to install OC in the VM for some reason though OS is same in both my machine and the VM (OS: Windows 2000 SP4).
thanks & regards,
S.Vasanth Kumar.

Serialization error while returning Value Object from Web Service

Hi
I have developed a sample Web Service (RPC based), it returns Customer Value Object
when client calls getCustomer method.
I have written a Client (attached the client source code) to invoke the web service
when the client invokes the Web Service it throws an Exception , the Exception

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 to get up and run a Web Services/RESTful functionality?

Hello there,
The DBAs just completed the upgrade for the APEX 4.2 in our organization. I was asked to work with APEX and build some application. This morning I was asked by my boss to take a look at getting the Web Services/RESTful API Functionality up and running. I am new to this environment. When I check the RESTful Services I found out the are no RESTful Services. What do I do to get this running? as a Developer, I do not have access to any schema or web services. How do I go about making this work? can any one point me to some blog or site that will help me make this work?

Hello,
You can consume Web-Services from APEX, but you can't produce. So first ask your boss which web-service you want to implement.
There are 2 types of web services in general, SOAP based and RESTful. APEX provides simplified API's to invoke both types web-service.
Identify web-service you want to TEST
Create ACL for APEX_XXXX schema to access web-service
Create ACL for Proxy Server as-well, if required
If web-service is SSL-enabled then configure wallet. See 17.7 Implementing Web Services
Use APEX API's to invoke Web-Services. See APEX_WEB_SERVICE
You can process XML response from Web-Service using Using XQuery with Oracle XML&nbsp;DB
If Web-Service returns JSON data either you can use PL/JSON | Free software downloads at SourceForge.net to process response, or you can process response at client side using jQuery

Hari

What shall I do after generate .dll from web services

Hi,
After I have successfully generate the .net classes from the web services, I proceed to generate the .dll from the .net. After which, what shall I do?? How shall I uses those classes?? Can someone advises me (newbie)??
Thanks alot!!

A .dll is in the .NET world like a .jar in Java Land, a packaging unit (or assembly). It does have very little to do with Web Services.
If you are starting with .NET and C# (or any other langague from the # collection), you should start by following some HowTo from Microsoft online documentation. The MSDN site seams a good place to start.
To call a Web Service hosted on the .NET framework from Java, you will need to locate the Web Service interface definition; the WSDL resource. Once you have this information, the easiest way to get started would be to build a Web Service proxy from JDeveloper, if you are planning on using the Oracle tech stack.
Hope it helps,
-Eric
