Invoking an ESB service from a PL/SQL procedure (URGENT)

Question

I used this utl_http example:
DECLARE
req Xxm_Web_Service_Client_Pkg.request;
res Xxm_Web_Service_Client_Pkg.response;
l_return_status VARCHAR2(2);
l_msg_count NUMBER;
l_msg_data VARCHAR2(2000);
BEGIN
req := Xxm_Web_Service_Client_Pkg.new_request('alta','xmlns="http://cliente.services.provisioning.vision.com"');
Xxm_Web_Service_Client_Pkg.add_TagGroup(req,'altaClienteParameters');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'apellido','xsd:string','deHaro');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'email','xsd:string','[email protected]');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'nombre','xsd:string','emilio');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'password','xsd:string','a');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'passwordInstalador','xsd:string','a');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'tipoCliente','xsd:string','1');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'username','xsd:string','1');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'versionContrato','xsd:string','1');
Xxm_Web_Service_Client_Pkg.add_TagGroup(req,'commonParameters');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'idAdmin','xsd:long','1');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'idCaller','xsd:long','9');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'idCliente','xsd:long','1000000');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'idEmpresa','xsd:long','1000');
Xxm_Web_Service_Client_Pkg.add_parameter(req,'idEntradaCaller','xsd:long','1');
Xxm_Web_Service_Client_Pkg.close_TagGroup(req,'commonParameters');
Xxm_Web_Service_Client_Pkg.close_TagGroup(req,'altaClienteParameters');
res := Xxm_Web_Service_Client_Pkg.invoke(p_init_msg_list => FND_API.G_TRUE,
p_url => 'http://198.137.253.178:7777/event/DefaultSystem/clienteService_RS',
p_action => 'alta',
x_return_status => l_return_Status,
x_msg_count => l_msg_count,
x_msg_data => l_msg_data,
x_req => req);
IF (l_return_Status != FND_API.G_RET_STS_SUCCESS) THEN
dbms_output.put_line(XXM_Util_Pkg.Get_Msg(l_msg_count));
END IF;
END;
The process deployed is an ESB service .However on execution of the above code I get the following message as the response from the server. Also there is no new instance of the ESB services created (to show that the service was triggered)
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/>
<env:Body>
<env:Fault xmlns:env="http://schemas.xmlsoap.org/soap/envelope/">
<faultcode>env:Server</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
<faultactor></faultactor>
</env:Fault>
</env:Body>
</env:Envelope>
I found the following messages in esb-rt J2EE Application log
Cluster Topology > Application Server: soasuite.esbprov > Log Files > Search Logs >
OWS-04052 Unable to determine operation id from SOAP Message
OWS-04005 An error ocurred for port: EventProvider: javax.xml.rpc.JAXRPCException: java.lang.NullPointerException
The soap message that I am using in the code (as input to the process) is
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema">
<soap:Body>
<alta xmlns="http://cliente.services.provisioning.vision.com/"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<altaClienteParameters>
<apellido>xxxxx</apellido>
<email>[email protected]</email>
<nombre>emilio</nombre>
<password>a</password>
<passwordInstalador>a</passwordInstalador>
<tipoCliente>1</tipoCliente>
<username>1</username>
<versionContrato>1</versionContrato>
<commonParameters>
<idAdmin>1</idAdmin>
<idCaller>9</idCaller>
<idCliente>1000000</idCliente>
<idEmpresa>1000</idEmpresa>
<idEntradaCaller>1</idEntradaCaller>
</commonParameters>
</altaClienteParameters>
</alta>
</soap:Body>
</soap:Envelope>
Another SOAP message when used directly to initiate the ESB services (by pasting this SOAP on Test WebService option) worked fined
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="http://cliente.services.provisioning.cablevision.com/">
<ns1:alta>
<altaClienteParameters>
<apellido>A</apellido>
<commonParameters>
<idAdmin>10</idAdmin>
<idCaller>10</idCaller>
<idCliente>10</idCliente>
<idEmpresa>1</idEmpresa>
<idEntradaCaller>10</idEntradaCaller>
</commonParameters>
<email>[email protected]</email>
<nombre>AAAA</nombre>
<password>sssss</password>
<passwordInstalador>sssss</passwordInstalador>
<tipoCliente>1</tipoCliente>
<username>cccccc</username>
<versionContrato>1</versionContrato>
</altaClienteParameters>
</ns1:alta>
</soap:Body>
</soap:Envelope>
Thanks in advance.

Answer 1

I change p_action value ( before p_action => 'alta' ) now ( p_action => '"alta"' )
res := Xxm_Web_Service_Client_Pkg.invoke(p_init_msg_list => FND_API.G_TRUE,
p_url => 'http://198.137.253.178:7777/event/DefaultSystem/clienteService_RS',
p_action => '"alta"',
x_return_status => l_return_Status,
x_msg_count => l_msg_count,
x_msg_data => l_msg_data,
x_req => req)
And the invokation an ESB service from a PLSQL procedure began to work fine !!!
Thanks for all answers
Thans Peter !!!
