Calling web service from JSP
Can anyone help??
I'm trying to call a webservice from within a JSP and i havent a clue how its done,
i have my IF and Impl and Client Coded and my stubs generated and service deployed and running, but i cannot figure out how to call the service from my JSP web-app.
Any help appreciated!
Hi ,
Its easy to call a WS from jsp what you can do is this. Think in manner that u will be keeping the client classes on a particular container, then in same container you can refrence the classes and can invoke service through a jsp..this works in my case.. it depends what kind of client do u want to create may be static or proxy or DII

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><font color=maroon>What All You Need To Do ? ...... as following</font></h3>
<b><font color=maroon>Step1).</font></b> Create a WebLogic Cluster (minimum two ManagedServers)
http://weblogic-wonders.com/weblogic/2010/04/28/weblogic-clustering-in-remote-boxes/
<b><font color=maroon>Step2).</font></b> 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/
<b><font color=maroon>Step3).</font></b> 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/
<b><font color=maroon>Step4).</font></b> Deploy your WebService on the Cluster
<b><font color=maroon>Step5).</font></b> Now Hit the WebService using the Proxy URL:
Example:
http://ProxyHostname:proxyPort/ServiceContextRoot/ServiceURI?WSDL

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.

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. -

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.DHi 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.
java.io.IOException: unable to find the type mapping resource file for:

at net.msl.sfx.ebooking.service.EBookingService.getBookingParties(EBooki
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?

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

TABLES
RESPONSE_ENTITY_BODY = RESPONSE_BODY

RESPONSE_HEADERS = RESPONSE_HEADERS
REQUEST_HEADERS = REQUEST_HEADERS

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.

How do i call web services from SAP ABAP
Hello,
Ian working with .net team. they are using sap .net Connector to connect SAP.

Please help me how to call web services from ABAP and how to pass value. Any one help me with example.
Thanks
RaviKumarHi 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.

Hi Friends,

Thanks in Advance.
Murali Krishna KIt is not possible to directly call a web service from SAP 4.6c.
Indeed, web service enablement is available as from Web AS 6.20, thus as from SAP R/3 4.7
So as described above, the solution is indeed to make use of PI(XI) for this.
