ORA-29541 while trying to access web service using UTL_DBWS

Question

Hi all,
Solicit your help in the beforesaid scenario:
I've 9.2.01 RDBMS, JPub 9.2.0.1.0 Production and OC4J Release 10.1.2 (standalone) environment and a local webservice.
While issuing jpub, I get the following response:
jpub -user=scott/tiger@ORACLE -sysuser sys/tiger -proxywsdl="e:\IMyFloatWebService.wsdl" -endpoint="http://10.177.238.71:8988/WS_Appln-WSFloat_prj-context-root/MyFloatWebService" -proxyopts=soap,tabfun -dir=FloatValue -plsqlpackage=soap_callout_wrap_eg -proxyopts=noload
Note: FloatValue\MyFloatWebServiceProxy.java uses unchecked or unsafe operations
Note: Recompile with -Xlint:unchecked for details.
FloatValue\MyFloatWebServiceProxyJPub.java
FloatValue\plsql_wrapper.sql
FloatValue\plsql_dropper.sql
FloatValue\plsql_grant.sql
FloatValue\plsql_revoke.sql
FloatValue\plsql_proxy.jar
Please run FloatValue\plsql_wrapper.sql in the user schema, load the generated j
ar file and run FloatValue\plsql_grant.sql in the SYS schema.
i. e - I get message as seen above:
"Please run FloatValue\plsql_wrapper.sql in the user schema, load the generated j
ar file and run FloatValue\plsql_grant.sql in the SYS schema."
And in sqlplus, while I try to access the web service, I get this error:
"SQL> sho user;
USER is "SCOTT"
SQL> SELECT soap_callout_wrap_eg.getCircumference(20)
2 FROM dual;
FROM dual
ERROR at line 2:
ORA-29541: class SCOTT.MyWebServiceFloatRTEProxyJPub could not be resolved"
Could somebody please advise me where I might be going wrong? Any help in this regards will be highly appreciated.
Regards,
Leslie

Hi,
I presume your Web Service needs HTTP (BASIC?) Authentication.
All this needs is setting the following 2 properties, which as can be seen, you are setting....
UTL_DBWS.set_property(l_call, 'USERNAME', '<username>');
UTL_DBWS.set_property(l_call, 'PASSWORD', '<pwd>');
This should work as long as your DBWS Callout Utility was downloaded from OTN after June 2008, and it's version is atleast 10.1.3.1.
Following is a sample code snippet that was tested successfully for this :
Declare
l_service UTL_DBWS.service;
l_call UTL_DBWS.call;
l_result sys.XMLTYPE;
l_request sys.XMLTYPE;
BEGIN
l_service := UTL_DBWS.create_service(null);
l_call := UTL_DBWS.create_call(l_service);
UTL_DBWS.set_target_endpoint_address(l_call, 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
UTL_DBWS.set_property(l_call, 'USERNAME', 'username');
UTL_DBWS.set_property(l_call, 'PASSWORD', 'pwd');
UTL_DBWS.set_property(l_call, 'OPERATION_STYLE', 'document');
UTL_DBWS.set_property(l_call, 'SOAPACTION_USE', 'true');
UTL_DBWS.set_property(l_call, 'SOAPACTION_URI', 'http://xxx.oracle.com:8888/basic/MyWebService1SoapHttpPort');
l_request := XMLTYPE('<Z_CENTRICITY_GET_DOCLIST
xmlns:urn="urn:sap-com:document:sap:rfc:functions">' ||
'<I_INCLUDE_OLD_VERSIONS></I_INCLUDE_OLD_VERSIONS>' ||
'<I_INSTITUTION>0001</I_INSTITUTION>' ||
'<I_PATIENT_NR>0000000181</I_PATIENT_NR>' ||
'</Z_CENTRICITY_GET_DOCLIST>');
l_result := UTL_DBWS.invoke(l_call, l_request);
UTL_DBWS.release_call (call_handle => l_call);
UTL_DBWS.release_service (service_handle => l_service);
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line(sqlcode || ' ' || sqlerrm);
END;
Hope this helps,
