Calling Web service from Java Concurrent Program

Hi,
I created a Java concurrent program and created executable. Here is my code.
 public void runProgram(CpContext ctx) {
 String value = "Java Concurrent Program Testing";
 Hello hell = new Hello();
 String returnValue = hell.testURL(value);
 if(returnValue.equalsIgnoreCase("TRUE")){
 ctx.getLogFile().writeln("-- Java Concurrent Program Testing --", 0);
 ctx.getOutFile().writeln("-- Java Concurrent Program Testing --");
 ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
 else{
 ctx.getLogFile().writeln("-- Hello World! --", 0);
 ctx.getOutFile().writeln("-- Hello World! --");
 ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
 }testURL() call the web service and get the response. but when I am selecting View Output option I am always geting out put as
-- Hello World! --I tested the logic of calling web service. It giving me out put "true". Here is my Web service calling code
 public String testURL(String Value){

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

Calling web Service from the Custom Adapter.Is it Possible?

Hi Experts,
I am having requirment in which i have to cal com.sap.aii.mapping.lookup.LookupService for calling web Service from the Custom Adapter.Is it Possible?
Regards,
Rajesh.D

Hi Rajesh..
Just looking the problem in another angle.. if there is no constraint that you have to use XI specific API to call the web service, why dont you use usual Java API used for calling a web service inside you custom adapter (I have Microsoft background.. donno exactly how it is done in Java,, but in .NET kind of a language it is possible). SInce your adapter is in Java itself and is capable of calling web service.. collect or lookup the data whatever you want and validate...
Just a thought..

Calling web service from MBean weblogic cannot find type mapping file

When calling web service from custom MBean i get java.io.IOException.

ngService.java:59)
The types.xml file is placed in same jar file as the classes such as net.msl.sfx.ebooking.client.BookingPartiesServiceService_Impl.
When calling the same class/method from a EJB, everything works fine and the web service is called.

i am having the same problem.
Do you have a solution now?
Thanks

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:

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..

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

How do i call web services from SAP ABAP

Hello,
Ian working with .net team. they are using sap .net Connector to connect SAP. But my job is In SAP side when Purchase Requisition is created, I have to call web services from ABAP and i have to pass the Purchase Requisition number to web service(.net Program). Please help me how to call web services from ABAP and how to pass value. Any one help me with example.
Thanks
RaviKumar

Hi Ravi,
If you can call EJB from ABAP and from EJB call Web service which you want to call. I am giving code to write in EJB business method processFunction.
public void processFunction(Function function) {
   IRepository repository;
   repository = new Repository("TestRepository");
   JCO.MetaData fmeta = new JCO.MetaData("ZTEST_EJB");
   fmeta.addInfo("REQUTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.IMPORT_PARAMETER, null);
   fmeta.addInfo("ECHOTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   fmeta.addInfo("RESPTEXT", JCO.TYPE_CHAR, 255,   0, 0,
   JCO.EXPORT_PARAMETER, null);
   repository.addFunctionInterfaceToCache(fmeta);
   JCO.ParameterList input =
   function.getImportParameterList();
   JCO.ParameterList output =
   function.getExportParameterList();
   JCO.ParameterList tables =
   function.getTableParameterList();
if (function.getName().equals("ZTEST_EJB")) {
                    output.setValue(input.getCharArray("REQUTEXT"),"ECHOTEXT");
output.setValue("This is a response " + table.getString("E_NAME") +" " + output.getName(1), "RESPTEXT");
else if (function.getName().equals("STFC_STRUCTURE")) {
JCO.Structure sin = input.getStructure("IMPORTSTRUCT");
JCO.Structure sout = (JCO.Structure)sin.clone();
try {
      System.out.println(sin);
   catch (Exception ex) {
       System.out.println(ex);
                    output.setValue(sout,"ECHOSTRUCT");
output.setValue("This is a response from Example5.java","RESPTEXT");
}//if
Here REQUTEXT, ECHOTEXT are import parameter and RESPTEXT is the Export parameter of Function module ZTEST_EJB in SAP.
Here from this bisuness method you can call web service which you want and give back the result of webservice to ABAP F.M.

Bhavik

Is there a way to call web service from 2 servers??

Hi,
I need to know if its possible to call web service from 2 different servers without having load balancer??? I mean, if one of the server has heavy work on, then it should call web service from the other server.
Thanks in advance.
Best Regards.

Hi,
WebLogic Cluster has this feature ( Load Balancing & Failover ). If you will deploy your WebService to a WebLogic Cluster and then If you will put a Proxy in front of it like (Apache)...Then it is Possible.
<h3>What All You Need To Do ? ...... as following</h3>
Step1). Create a WebLogic Cluster (minimum two ManagedServers)
http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
Step2). Install a Proxy like Apache in frot of them like following:
http://weblogic-wonders.com/weblogic/2010/05/13/apache-proxy-as-static-content-repository/
Or
http://weblogic-wonders.com/weblogic/2010/08/01/weblogic-httpclusterservlet-proxyserver/
Step3). Now Configure a FrontEnd Host for your Cluster by providing the ProxyServer Host name as the FrontEnd of your Cluster. This step is required to Generate the Dynamic WSDL with the Address of the Frontend.(Not of a perticular WebLogic Server)
http://weblogic-wonders.com/weblogic/2010/06/21/configuring-frontend-host-and-port/
Step4). Deploy your WebService on the Cluster
Step5). Now Hit the WebService using the Proxy URL:
Example:
http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL

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 web service from Obiee

Hi,
I want to get data from webservice and show the results in a dashboard.
I checked http://www.artofbi.com/index.php/2009/08/consuming-a-web-service-in-obiee-presentation-services-using-jquery-cdn/ web site.
But the author is retrieving data from a web page by sending parameter to querystring like

But as I know we can not call web services with parameters like this.

Calling Web Service from CRM using proxy

Hi all,
I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
Is there any way to remove SOAP envelope from the response while mapping?
Is it possible to call web service from WAS 620?
Thanks!!!!
Anya.

Hi Manish,
SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
What can I do?
Cheers,
Anya.
