Error calling web service from Viusal Composer

Hello:
I'm accessing entity services methods published as web services from a composite application from Visual Composer. I'm using version 7.0 SR3 SP15.
Iu2019m able to access create and read methods from entities services. But from same getAll() methods Iu2019m getting access error. When I execute the same getAll() method from u201CWeb Service Navigatoru201D it works ok. But from Visual Composer itu2019s not working. That happens only for same entities for others itu2019s working ok.
From VC Iu2019m able to select the WDSL and use I in the iViews. The other methods of the iView works ok except for the getAll.
I have already set the options of VC to not keep a cache of web services definition and review and recreate the system in portal landsacape and teh related alias to access the web services. I have laso checked te user and password in the mapping.
Thabk you in advance for your help.
Regards.

Hello:
Using the infprmation in the link that you pass me I was able to look into the log files and see what the problem is.
The getAll service as it is geerated by NWDS receive an input paramter:
queryFilter (test.types.p1.GetAllQueryFilter)
In VC when I drop the getAll method from the corresponding service data into the working area. That input parameters doesn't apper aonly the output parameter.
Then when I execute or test that service. The portal is giving an error:
Full Message Text
com.sap.engine.services.webservices.additions.soaphttp.exceptions.ProcessException: Cannot find the required parameter [queryFilter] in request message
But that parameters was never recognized by VC.
Thank you in advance for your help again.

Error calling web service from Adobe form

Hi Experts,
While calling web service form my adobe form, i was getting an error as below saying "Error attempting to read from the file" followed by the URL of my web service.
To create the above scenario i followed the following steps:
1. Create a Function module and create a web service from that function module.
2. Through SOAMANAGER, download the WSDL file for the generated web service.
3. Create an Adobe form with an empty Interface and create a new Data Connection on the form using the downloaded WSDL.
4. Generate this adobe form using an ABAP report.
Kindly extend help on this to figure out if I'm missing something!!!

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.

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
Thanks

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..

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.

Hope this helps...

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

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.
Regards,
Bhavik
