! How to start Web Services in Java?

Hi,
I am just wondering if someone knows how I can start Web Services with Java?

The best place to start is at the beginning of the tutorial. If you've downloaded and installed the jwsdp pack, then download the tutorial and read from the start.
When you come to more specific problems then post again.

How to start Web Service Creation Tool in CRM 6.0 ?

Hi,
I am trying to create new web service in CRM 6.0. I have gone through the documentation and no where I see how to start this tool. Can anyone explain how to start this tool please.
Thanks for reading this message. Your help will be appreciated.
Regards,
Phani.

Hi,
There are 2 ways how you could call up the WebService Tool. The first one is already described before, this is directly from the component workbench (see comment before) in the test mode.
The second one is to integrate it into any role directly and start it directly from that role. Therefore you have to do the following:
1. Go to the IMG - Customizing in SAP Gui (transaction SPRO)
2. there in Customer Relationship Managment-> UI Framework-> Technical role definition enter "define navigation bar profile"
3. There you will find an logical link (which is the basis for you beeing able to navigate to the WebService tool) named "WEB-SER".
4. You have to assign this link in the next folder to a Work Center Link Group under "assigned links"
5. Then you go to the next folder "Define Work Center" and there you assign your "work center link group" to a work center
Now you have done the basics and now you have to decide in which Role you want to have it displayed. Therefore you go to "Define Profile" further down in the same Tree
1. Select the role where you want to assign the Work Center to
2. Go to assign WorkCenters and add it there
3. Decide on the position number where the work center should appear in your role.
If you have done this you should and you have not done it so far, go to "Business role" (you could do this in IMG or in the WebUI). As you are already in IMG lets assume you stay there:
1. Go to "Define Business Role"
2. Check at the details of the business role that your Navigation bar Profile used in "Define Profile" above is assigned to your business role
3. Go to "Adjust Work Center" and make sure your work center is there and is not set to "invisible".
4. In "Ajust Work Center Link Groups" decide if the your new entrie should be displayed in the 2nd Level Menue of your role via flagging "in menu" or if it just should be reachable via the work center (not flagging in menue) but have it visible.
Via this the new entry should appear in the Work Center (when the user is pressing on the left side just the button of your Work Center or also in the second level menue when he uses the little arrow on the Menue itself.
Hope this helps

Java Project + C#.Net Web Service = Integration
1. Do i need to create a Web Service too for the Java Project? If yes, What are the necessary tools needed for the creation of this Java Web Service?
2. The .NET Web Service is available online. (It is made by other people).
3. Based on the equation, what is the equivalent technology for the + sign?
4. Can you site a concrete example for accessing a web service?
5. I'm new here. Totally I have no idea where to start.

Hello
Thanks a lot for your help ...
I am developing simple J2EE based web service client using IBM WSAD 5.1. I have used the following code to call .asmx web service in Java
String url = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
     String namespace = "http://tempuri.org/";
     name = request.getParameter("txtName");
     try
          System.out.println("In Internet Service");
          ServiceFactory factory = ServiceFactory.newInstance();
          Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
          System.out.println("Got Service......");
          Call obj = (Call)serv.createCall();
          System.out.println("Got Call......");
          obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
          obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
          obj.setTargetEndpointAddress(url);
          obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
          obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
          obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
          obj.setReturnType(XMLType.XSD_STRING);
          System.out.println("Parameters Set.....");
          Object[] params = new Object[]{name};
          k = (String)obj.invoke(params);
          System.out.println("Result: "+k);
     catch(Exception e)
        System.out.println("Exception is : "+e);
    }But this code is throwing exception that
Invalid Address "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"I have also tried this URL with Java Proxy. But it showing the same error.
Plz can u tell me how to access .asmx web service ?
Waiting 4 reply.

(261680070) Q SYNCH-11 How do my web service methods accees EJBs and java classes?

A<SYNCH-11> How do my web service methods accees EJBs and java classes?
A<SYNCH-11> It is simple to use java classes, just do it as you would ordinarily.
The .jws file really contains a simple class so you can program with it in the same
way that you would use a regular Java class.
To use an EJB you can go and access it directly as you would with any EJB remote
client (lookup home stub, create, etc) or if the EJB is deployed to WLS you can use
a control to provide a very simple wrapper to the EJB. We will see this in detail
on Thursday in the ADVC module.

Futher information about the possibility of callback:
It may be possible for a synchronous only web service (i.e. MS .net) to even paticipant
in the callback functionality of asynchronous web services. If the client implements
the appropriate methods for the callback but listens for them on a different port
or binding than the SOAP request, then web service may be able to build a response
if the client's "callback URL" is submitted as the beginning part of a conversation.
Watch the BEA developer forum (http://dev2dev.bea.com) for more information about
this approach and other tips and techniques for building web services.

Q<SYNCH-03> I heard that MS .net only implements synchrnonus method? If
this is true.
Does it means my async methods will only work with J2EE clients?
A<SYNCH-03> I do not know the limitations of .net but let me point out that
is very
difficult to provide asynchronous web service method invocation (this is
different
from an asynchronous web service). HTTP as a general communication protocol
is based
on a request and response paradigm so your client libraries will mostly
likely be
expecting a response even if it is empty (check the asynchronous example
from today
to see that the start method still returns an empty response). You must
distinguish
this from the notion of an asynchronous web service which is a business
operation
that occurs on the server whose return value/result is not directly associated
with
building response to the client. An asynchronous web service can (and generally
will)
be started and stopped with web service operations that are invoked synchronously.
Thus MS .net clients can still be client to WLS hosted web services.

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you
Best Regards

How to Trigger CAF web services from java Job schedulers?

Hi Experts,
I am in need of calling CAF based web services from custom Job scheduler.
Could you please provide your idea and input if anyway we can call such web service by java api in custom jobs development?
Thing is that we have CAF BO which hold around 1 million record (master data) and based on approval scenario (developed in WDJ apps) we will have to move this record to another business object for further manipulation?
Hence due to huge number of record in BO, I would like to automate this activity by calling Jobs from WDJ apps and then Job will trigger the CAF web service which would create record into the BO object.
Please share your idea and let me if it can be achievable by java apis to trigger Jobs by WDJ apps & webservice by jobs?
Thanks & Regards,
Pankaj

Firts of all, i would like to ask if it 's something difficult to be done. Secondly i would appreciate if someone gave me a guideline about how to start the implementation of the web service.
Thanks in advance. :)

Thanks for the reply !I have read a lot of things about web service. i m reading about a week now for web services :)Well, you probably won't be able to do it with just a week of reading.Maybe a "hello world" type of webservice producer + consumer, if you know Java and web environments properly. JAX-RS is a bit easier in my opinion though, its a very well-defined API and I had a setup between Java and Ruby on Rails running in an afternoon. If you take the time to read and understand the material first of course. Especially the understanding part is what people tend to want to skip over.
We can't just "give a hint" and you'll be magically able to write a webservice. Programming doesn't really work that way.Indeed, and software engineering works even less like that. It happens to be bloody hard.

Parse errors while creating a Web service from Java class!

Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

Calling a Web Service from Java

Our java guru (who is out sick....AHHHH) created all the calls that are needed to access the web service that he has running. For example the call getLongList(String user, String password) will return a list of all outstanding transactions. He made a jar file that has service has class files for PortType, Service, Service Locator and Soap Binding stub.
How do I call this web service from java? Do I have to import it into my classpath? or just call these parameters from within my java code?

never mind...i got it

Calling a Web Service from Java Webdynpro

Hi,
Can any one give me step by setp details on how to call a Web Service from Java Webdynpro ?
I tried creating a model using Import Web Service Model but when I completed creating the model, I got some errors as shown below.
Error The method setRouteGeometryLineArray(double[][]) in the type Trip is not applicable for the arguments (double[]) ComplexType_Trip.java WS_INVOKE/gen_wdp/packages/com/cintas/test/model/p1 line 249
thanks
SBK

Hi SBK,
I assume you may already have read the [help guide|http://help.sap.com/saphelp_nw70/helpdata/EN/81/12703e5da3e946e10000000a114084/content.htm] This gives a pretty good idea of how to do it (step by step).
Is there a typo in the error you pasted?
Error The method setRouteGeometryLineArray(double][) in the type Trip is not applicable for the arguments (double[]) ComplexType_Trip.java WS_INVOKE/gen_wdp/packages/com/cintas/test/model/p1 line 249
The square brackets [] after double in the method call appear to be reversed. Is that also in the code? or just a mistake here?
Hope this points you in the right direction.
BRgds,
Simon

Web Service From Java class, serialization problem

Hi,
I want to create Web Service from Java class, I made java project, generated web service from it, create web service archive project and deployed it to WAS 6.40.
My class have 2 methods,
public int add(int a, int b);
public MyResponse doSomthing(MyRequest req);
I can succesfully call add method from Web Service Navigator, it works fine but when I call doSomthing methods I get the following error:
<b>
Deserializing fails. Nested message: XML Deserialization Error. Result class [com.mycomp.sap_tech.ws.MyRequest] does not have property [Amount] of type [java.lang.String]. It is required to load XML..
</b>
Any ideas how to resolve it?
P.S. MyRequest class is exposed throw VI, has default constractor and public getters and setters for all properties. It implements Serializable as well. Any guesses?
Thanks in advance,
Victor.

Hi Bhavik, thanks for response.
as I already mentioned it implements Serializable, so it is not the problem.
Thanks Avi but it didn't helps iether
