Exception in calling web service from OAF page.

Hi,
I am trying to invoke a web service from OAF.
But my code error out at particular statement where I am sending the message i.e. at
SOAPMessage reply = connection.call(message, destination);
The error message is
java.security.privilegedactionexception: javax.xml.soap.SOAPException: Message send failed: For Input string "".
I am using the wsdl link in destination variable-
String destination = "http://soad.xxxxxxxxxx.org:80/soa-infra/services/default/xxxxxx/xxxxxxx?WSDL";
Please help me with the solution.

Have you tried submitting your help request on the SmartBear soapUI forum?

Or if a soapUI Pro user:

Exception when calling web service from Oracle forms 10g

Hi All,
I am trying to integrate Oracle Forms 10g(V 10.1.2.0.2.) with Web Services.
There is a java class named 'authenticate' which is generated using Oracle JDeveloper.
This class is included in the forms application by using "Import Java Class" feature.
Forms built the following funtion based on that class:
-- Method: authenticate (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
FUNCTION authenticate(
obj ORA_JAVA.JOBJECT,
a0 VARCHAR2,
a1 VARCHAR2) RETURN VARCHAR2 IS
BEGIN
args := JNI.CREATE_ARG_LIST(2);
JNI.ADD_STRING_ARG(args, a0);
JNI.ADD_STRING_ARG(args, a1);
message('here1');
RETURN JNI.CALL_STRING_METHOD(FALSE, obj, 'mypackage/AuthenticatorWebServiceServiceStub',
'authenticate', '(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;', args);
message('here2');
END;
However when the above code is invoked it shows the message 'here1' on the form and then throws the following exception: java.lang.Exception: java.lang.ClassCastException
Please suggest me what's wrong with the code. I appreciate your time and help.
Thanks,
Scott.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
Thanks

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
yqlq=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22YHOO%22%2C%22AAPL%22%2C%22GOOG%22%2C%22MSFT%22%2C%20%22PTRY%22)&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=?";
But as I know we can not call web services with parameters like this.
How can I call web service from BI?

Hi,
I controlled this document. The document is explaining Oracle BI web services for extracting information from Oracle BI and showing them in other environments. But I want to get results from a web service ( for example a web service which returns currency rates, weather information or sharepoint lists) and then represent them in Oracle BI Dashboards.

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.

Yes, SAPHTTPA (runs on application server) and/or SAPHTTP (runs on front-end pc), one of which, is required for HTTP communication. So far, nothing too elaborate as far as SOAP goes, but the logic is simplistic. Here's some sample code:
DEST = 'SAPHTTPA'.
TRANSLATE HOST TO LOWER CASE.
MYURL = 'wssrvTest/Service.asmx/GetByOrderItem'.
CONCATENATE HOST MYURL INTO MYURL.
REQUEST_HEADERS-DATA =
 'Content-type: application/x-www-form-urlencoded'.
APPEND REQUEST_HEADERS.
CLEAR REQUEST_HEADERS.
*........Convert Order Number to External Format........................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = ORDER
 IMPORTING
 OUTPUT = ORDER.
*........Convert Item Number to External Format.........................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = ITEM
 IMPORTING
 OUTPUT = ITEM.
*........Convert Material Number to External Format.....................
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
 EXPORTING
 INPUT = MATERIAL
 IMPORTING
 OUTPUT = MATERIAL.
CONCATENATE 'sOrder=' ORDER
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CONCATENATE '&sItem=' ITEM
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CONCATENATE '&sMaterial=' MATERIAL
 INTO REQUEST_BODY-DATA.
APPEND REQUEST_BODY.
CLEAR REQUEST_BODY.
CALL FUNCTION 'HTTP_POST'
 EXPORTING
 ABSOLUTE_URI = MYURL
 RFC_DESTINATION = DEST
 BLANKSTOCRLF = 'X'
 TABLES
 RESPONSE_ENTITY_BODY = RESPONSE_BODY
 REQUEST_ENTITY_BODY = REQUEST_BODY
 RESPONSE_HEADERS = RESPONSE_HEADERS
 REQUEST_HEADERS = REQUEST_HEADERS
 EXCEPTIONS
 CONNECT_FAILED = 1
 TIMEOUT = 2
 INTERNAL_ERROR = 3
 TCPIP_ERROR = 4
 DATA_ERROR = 5
 SYSTEM_FAILURE = 6
 COMMUNICATION_FAILURE = 7
 OTHERS = 8.
CHECK SY-SUBRC = 0. "more appropriate msg goes here
LOOP AT RESPONSE_BODY.
 IF RESPONSE_BODY+0(7) <> '<string' AND
 RESPONSE_BODY+0(8) <> '</string' AND
 RESPONSE_BODY+0(5) <> '<?xml'.
 SPLIT RESPONSE_BODY-DATA AT '=' INTO FIELD_NAME FIELD_VALUE.
 TRANSLATE FIELD_NAME TO UPPER CASE.
 CASE FIELD_NAME.
 WHEN 'HEIGHT'.
 HEIGHT = FIELD_VALUE.
 WHEN 'WIDTH'.
 WIDTH = FIELD_VALUE.
 WHEN 'LENGTH'.
 LENGTH = FIELD_VALUE.
 WHEN 'WEIGHT'.
 WEIGHT = FIELD_VALUE.
 WHEN 'QTY'.
 QTY = FIELD_VALUE.

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 it possible to call from OAF.....?
If possible can any body give some steps how to call.............?
Thanks,
UMA.

Uma,
If your are working on R12, calling web service is very easy. There is a stub generation wizard in Jdeveloper, where you just need to provide url for the web service, and it will automatically generate the stub classes. This stub class can then be used like normal java classes in your code. If you are working on 11i, then its a little tricky task, where you need to import some jar files for supporting your stubb(proxy) casses. There jar file refrence is then also needed to be added in jserv.properties file on Apache Jserv on 11i.

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)

Step2). Install a Proxy like Apache in frot of them like following:

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

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..
