Java to Webservices ??

Hi friends,
Can someone tell me a high level idea on how to interact with the Webservices
like I have one Standalone Java application which need to interact with some Webservices to validate something.
Is it possible to talk from Java to Web Services?
To interact should I have some server to put the request to the web service ?
Or can some of JAVA API could help to put the request to the web service to specific port ?
Any idea would be much appreciated.
With Cheers,
Prasanna

Sure, you can create client and server artifacts to communicate via webservices in Java.
One of the main resources you sould check is :
https://jax-ws.dev.java.net/
The server side might live in an HTTP server that runs java. You can use glassfish, tomcat, etc. That's because most webservices use HTTP as a transport layer, but it is not limited to such a protocol.
If you want to be involved with webservices, you should use netbeans 6 with webservices support, and then you will be able to see how easy is to program webservice clients.

Invalid SOAP action when using java ws WebService

Hi all,
this is a slightly more detailed error for a problem i posted recently. I am connecting to a web service that was generated from WSDL. It has two methods "HelloWorld" and "HelloSayFirstName". As defined in the WSDL, the methods use the SOAP action document style. I want to add a cookie to the http header, so after the port is created, I use the following to add the header to the requestContext:
          BindingProvider bindingProvider = (BindingProvider) servicePort;
          Map<String, Object> requestContext = bindingProvider.getRequestContext();
          List<String> cookies = new ArrayList<String>();
          cookies.add("mycookie=mytoken");
          HashMap<String, List<String>> httpHeaders = new HashMap<String, List<String>>();
          httpHeaders.put(HTTPConstants.HEADER_COOKIE, cookies);
          requestContext.put(MessageContext.HTTP_REQUEST_HEADERS, httpHeaders);
This works when I call the first method (HelloWorld) - the first activity message sent to the server contains the following:
<HttpRequest>
<Method>POST</Method>
<QueryString></QueryString>
<WebHeaders>
<Cache-Control>no-cache</Cache-Control>
<Connection>keep-alive</Connection>
<Pragma>no-cache</Pragma>
<Transfer-Encoding>chunked</Transfer-Encoding>
<Content-Type>text/xml; charset=UTF-8</Content-Type>
<Accept>*</Accept>
<Cookie>mycookie=mytoken</Cookie>
<Host>exampleHost</Host>
<User-Agent>Java/1.5.0_14</User-Agent>
<SOAPAction>"http://tempuri.org/IMyService/HelloWorld"</SOAPAction>
</WebHeaders>
</HttpRequest>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<To s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://exampleHost/WebServices/WCFService/Service.svc</To>
<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/IMyService/HelloWorld</Action>
</s:Header>
<soap:Body>
<HelloWorld xmlns="http://tempuri.org/" xmlns:ns2="http://schemas.datacontract.org/2004/07/" xmlns:ns3="http://schemas.microsoft.com/2003/10/Serialization/">
<myValue1>world</myValue1>
</HelloWorld>
</soap:Body>
</soap:Envelope>
However, after this method, the httpHeaders in the requestContext object have been updated to include the "Accept" header and the "SOAPAction" header - which is the incorrect action! Now, when I call the method "HelloSayFirstName" I get the following:
<HttpRequest>
<Method>POST</Method>
<QueryString></QueryString>
<WebHeaders>
<Cache-Control>no-cache</Cache-Control>
<Connection>keep-alive</Connection>
<Pragma>no-cache</Pragma>
<Transfer-Encoding>chunked</Transfer-Encoding>
<Content-Type>text/xml; charset=UTF-8</Content-Type>
<Accept>*</Accept>
<Cookie>mycookie=mytoken</Cookie>
<Host>exampleHost</Host>
<User-Agent>Java/1.5.0_14</User-Agent>
<SOAPAction>"http://tempuri.org/IMyService/HelloWorld"</SOAPAction>
</WebHeaders>
</HttpRequest>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<To s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://exampleHost/WebServices/WCFService/Service.svc</To>
<Action s:mustUnderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://tempuri.org/IMyService/HelloWorld</Action>
</s:Header>
<soap:Body>
<HelloSayFirstName xmlns="http://tempuri.org/" xmlns:ns2="http://schemas.datacontract.org/2004/07/" xmlns:ns3="http://schemas.microsoft.com/2003/10/Serialization/">
<dataContractValue></dataContractValue>
</HelloSayFirstName>
</soap:Body>
</soap:Envelope>
It seems that the SOAPAction in the http header and the soap header is incorrect. Is there any reason why the requestContext would keep hold of the action that was previously called, and not use the new action? I'm stumped here - any help would be greatly appreciated.
Cheers.

Does not only happen when using JAX-WS.
the following servlet code is enough to reproduce the problem :
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/xml;charset=\"utf-8\"");
It only occurs on 10.1.3.4.0 (works fine on 10.1.3.3.0 and 11.1.1.1.0 TP4)

XML not well formed - Java Mapping, Webservice to RFC Scenario

Hello All Experts,
I have facing a strange type of error. I have written a Java Mapping which implements a DOM parser to take a request from a Webservice and validate it on the basis of some prerequisites. i.e. If data in the incoming request is valid, it creates a message of the same structure type as the input. If the incoming data is incorrect or incomplete; It generates an Error response structure.
When I run and test the same mapping program using Editplus Java editor for the error scenario; it executes perfectly and creates the correct error XML structure. (I checked it by importing the structure in the XI Message mapping test tab). But when I create jar of my java mapping program and test it in my interface mapping, it gives me "XML not well formed error" (Problem while building the tree).
Any idea as to why is it behaving in such a way? There are 2 reasons which come to my mind as of now:
1. The initilization of my input and output streams in the public static void main:
            InputStream in = new FileInputStream(new File("Input.xml"));
           OutputStream out = new FileOutputStream(new File("Output.xml"));
           validateXML myMapping = new ValidateXML();
            myMapping.execute(in, out);
The Output.xml has the xml structure for the correct case, do I have to initialize my outputstream for the error file? say error.xml
2. My Webservice interface is a sychronous interface (Request / Response) and output of the Java mapping program are two asynchronous interface. (I'll use a synch-asynch bridge when this works) - Is that causing a problem?
Please help.
Best regards,
Varun

Hello Varun,
it gives me "XML not well formed error" (Problem while building the tree).
I have come across the same error message while testing in interface mapping. My problem was when an exception occured in java mapping, the execution terminates with the messages XML not well formed error". In order to solve this issue what i did was catch the exception type TransformerException and in that catch block throw StreamTransformationException exception in main methos of mapping program i.e execute().
eg:-
catch (TransformerException e) {
               throw new StreamTransformationException("Can not write XML.", e);
By doing this you will see the exception raised , because some times when you execute your mapping with mail() method, though it create the file, when you try to open it will give error if any exceptions occured in mapping. By using the above notation you can handle those in java mapping.
Hope you have gone through this blog.

Java application -- webservice --- XI ( RFC ) ?

Hi friends ,
            <b>        My scenario is like I want via web service I need to pass request to RFC and get the response back . This calling webservice is external java application .</b>
                   Can u please tell me What steps i have to do in XI ?
                   I have to do synchronous Interface between RFC and webservice right ?
                   <b>First I have done this scenario by designing IR and in Configuration I have used SOAP Sender and RFC Receiver adapter . Using Synchronous Interface</b>
                   Using Tools -- > Define WebService . I have Defined that   as WebService . I has creatd the WSDL File for me.
                   I have given the SWDL file and the URL like the following
http://xidev:8021/XISOAPAdapter/MessageServlet?channel=:BS_DISTANCE_CHECK_SOAP:CC_DistanceCheck_SOAP_Sender

                  But the java guys try to use this URL in their web service calling module it is not working .
        <b>          The way what i have done is corret ?</b> or something i have to do ?
               <b>   What input i have to give to Java Guys to call the webservice ?</b>

Hi Bhavesh ,
                  Thanks for your reply.
               Then that URL and WSDL File Which i have given to the Java guys is enough ?
                I have one doubt .I don't know much about the webservices .
                Don't we need SOAP Receiver Adapter for this ?
                How the external application will get back the result ?

Urgent :: 11g Invoking Composite from Java/From Webservice Proxy

Hi All,
i have a requirement where in need to when ever the exception occurs it invokes custom java and then it invoked a BPEL process to handle the errror.
in 10.1.3.4 i used to Java Api to invoke the BPEL process and it works fine.
1) . now we are migrating to 11g, i know this API wont work with 11g as the server is on weblogic and client librairies may be different for invoking in composite it in 11g. if any body has invoked a composite using java and the using 11g libraries to invoke the composite ? if so can you please post here ?
2). otherway i tried to create a Web Service proxy using Jdeveloper for the composite, when i test it using Jdeveloper it is working fine, but when i place it in the lib directory, im getting a bad response from server 503.
please see logs below for the second approch

if any body has already implemented the invocation of composite in one of above approaches, please let me know.
any pointers to resolve this will be of great help

Here is sample to invoke a composite from JSP, this should be same from Java Class. Note that the composite should use adf binding and not ws binding.
Here is snippet of composite.xml service:
<service name="rmibpel_client_ep" ui:wsdlLocation="RMIBPEL.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/Application1/RmiVsSOAP/RMIBPEL#wsdl.interface(RMIBPEL)"/>
<binding.adf serviceName="rmibpel_client" registryName=""/> </service>
Note the binding should be binding.adf and not binding.ws
Sample jsp:
<%@page import="java.util.Hashtable" %>
<%@page import="java.util.Map" %>
<%@page import="javax.naming.Context" %>

How make setting Java Application Webservice can Test?

hi,
there is a possibility of creating executables from java classes: Microsoft Visual J++
However, you'll always need a virtual machine, even the executables created with MSVJ++ require the Microsoft Virtual Machine - either bundled with the exe file or installed on the user's system.

a java class Test.java and number of other third party libraries and my own java
files that are reffered in Test.java. I want to expose the public methods in Test.java
as webservices.
the serivegen part of My build.xml is as below
<servicegen
destEar="${APPLICATIONS}/${ear_file}"
warName="${war_file}">
<service
javaClassComponents="com.verizon.Test"
targetNamespace="${namespace}"
serviceName="Test"
serviceURI="/Test"
generateTypes="True"
expandMethods="True">
</service>
<classpath>
<pathelement path="${build}"/>
<pathelement path="${java.class.path}"/>
</classpath>
</servicegen>
When i run ant it complains:
[servicegen] weblogic.xml.schema.binding.BindingException: Invalid class received:
interface org.apache.crimson.tree.ElementFactory loaded from file:/apps/opt/crimson.jar!/org/apache/crimson/tree/ElementFactory.class.
All classes that will be serialized or deserialized must be non-interface, non-abstract
classes that provide a public default constructor
I have no clue,Why is Servicegen introspecting the third party class file also?I
just need the public methods in Test.java exposed and Test.java will just use
the third party library.
also,is there a way to tell servicegen to include all these java files X,Y,Z to
the war file/ear files but expose only the public methods of X in the WSDL.
Please help
thanks

Hi Bruce,
Thanks very much for the insight u provided.Yes one of my public methods was returning
a element factory.
But let me ask my question this way:
Is there a way to tell servicegen to take only the specified public methods in
a class to make them as webservices?
by default servicegen is taking all the public methods..,i workaround i found
is to deploy the webservice manually by writing the web-services.xml to include
only the required public methods.
thanks

Hi Suresh,
Does your Test.java have a public method that returns the element
factory of an XML document, like "public ElementFactory
getElementFactory ();" or such?
If so, you may want to check out the supported build-in and non-built-in
data types:
http://edocs.bea.com/wls/docs81/webserv/assemble.html#1060696
Concerning your last question, you can use the excludeEJBs, includeEJBs
(in combination with the ejbJar attribute) to specify which non-built-in
data type components should be generated. Or if you use the
javaClassComponents then simply use a comma separated list of class
names.
Hope this helps,
Bruce

How to call webservices in business objects from java

hi everyone, i am having a scenerio were a program which is written in java, this java program will instantiate when i get the data into my database. the java program need to fire and pass the parameters to the webservices in the business objects to create a file depending upon the parameters which r passed by the java to webservices. how i need to cinfigure in business objects webservicess,to get what i am looking or what r the things i need
we r using xi 3.1 sp3, web application server tomcat.

Hi,
case 1: for WDP, you can create the web service model via "Import Adaptive Web Service" or "Import Web Service Model (deprecated)" by supplying wsdl URL.
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/wdjava/faq%2b-%2bmodels%2b-%2badaptive%2bweb%2bservice
case 2: In ABAP, create a proxy object at trx code SE80.
http://help.sap.com/saphelp_nw04s/helpdata/en/bf/d005244e9d1d4d92b2fe7935556b4c/frameset.htm
Both cases are wizard-based. It's pretty intuitive.

Error while invoking a webservice using Axis deployed in tomacat from Bpel

Hi,
I am trying to invoke a Axis webservice(from Java class to WSDL- bottom up java bean webservice approach) developed in Exclipse IDE, deployed in Tomcat.
When i am trying to invoke the service, from Bpel from Jdeveloper it is throwing error as such :
Invoke_1 (faulted)
[2009/05/22 14:32:18] Faulted while invoking operation "storeLoanData" on provider "LoanDataPersist".less

</messages>
I may add that, the WSDL generated is using "soap:enc:array ", rpc style.
Can anyone tell me the reason and suggest .

Hi Marc,
Thanks for the guidancer. But sir, i am unable to detect at which place i have to do the required changes.I found p_request as a parameter in the method only in the interface only.
As bcos ultimately , i am generating the tomcat /axis web service (WSDL) from the java class, which is using 2 Request and response java bean, in which they are doing someing like this:
private static org.apache.axis.description.TypeDesc typeDesc =
new org.apache.axis.description.TypeDesc(LoanDataPersistRequest.class, true);
static {
typeDesc.setXmlType(new javax.xml.namespace.QName("http://dtos.demo.com", "LoanDataPersistRequest"));
org.apache.axis.description.ElementDesc elemField = new org.apache.axis.description.ElementDesc();
elemField.setFieldName("customerName");
elemField.setXmlName(new javax.xml.namespace.QName("", "customerName"));
elemField.setXmlType(new javax.xml.namespace.QName("", "string"));
elemField.setNillable(true);
etc etc...................}
And second thing is when the WSDL is generated, from that the stubs and skeletons is generated to test the service.
There in the Stub i found out "p_request" in this place:
private static void _initOperationDesc1(){
org.apache.axis.description.OperationDesc oper;
org.apache.axis.description.ParameterDesc param;
oper = new org.apache.axis.description.OperationDesc();
oper.setName("storeLoanData");
param = new org.apache.axis.description.ParameterDesc(*new javax.xml.namespace.QName("", "p_request")*, org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://dtos.demo.com", "LoanDataPersistRequest"), com.demo.dtos.LoanDataPersistRequest.class, false, false);
oper.addParameter(param);
oper.setReturnType(new javax.xml.namespace.QName("http://dtos.demo.com", "LoanDataPersistResponse"));
oper.setReturnClass(com.demo.dtos.LoanDataPersistResponse.class);
oper.setReturnQName(new javax.xml.namespace.QName("", "storeLoanDataReturn"));
oper.setStyle(org.apache.axis.constants.Style.RPC);
oper.setUse(org.apache.axis.constants.Use.ENCODED);
_operations[0] = oper;
And in skeleton :
static {
org.apache.axis.description.OperationDesc _oper;
org.apache.axis.description.FaultDesc _fault;
org.apache.axis.description.ParameterDesc [] _params;
_params = new org.apache.axis.description.ParameterDesc [] {
new org.apache.axis.description.ParameterDesc(*new javax.xml.namespace.QName("", "p_request")*, org.apache.axis.description.ParameterDesc.IN, new javax.xml.namespace.QName("http://dtos.demo.com", "LoanDataPersistRequest"), com.demo.dtos.LoanDataPersistRequest.class, false, false),
oper = new org.apache.axis.description.OperationDesc("storeLoanData", params, new javax.xml.namespace.QName("", "storeLoanDataReturn"));
_oper.setReturnType(new javax.xml.namespace.QName("http://dtos.demo.com", "LoanDataPersistResponse"));
_oper.setElementQName(new javax.xml.namespace.QName("urn:com.demo.service", "storeLoanData"));
_oper.setSoapAction("");
myOperationsList.add(oper);
if (_myOperations.get("storeLoanData") == null) {
_myOperations.put("storeLoanData", new java.util.ArrayList());
((java.util.List)_myOperations.get("storeLoanData")).add(_oper);
PLease suggest if i make some changes in stub and skeleton how it would reflect the WSDL... or else please suggest where shud i do the required changes.
