Failed to get WSDL service "Text" from WSDL definition

4501Feb 25 2005 — edited Mar 7 2007
Hello,

I am testing User Task BPEL process. All functions correct except for the last service in the BPEL process, the callBackClient process.
This process returns the following error
<bindingFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="code">GenericError</part>
<part name="summary">Failed get wsdl service definition. Failed to get WSDL service "Text" from WSDL definition "{http://www.demo.com/checkCredibility}Demo". Please verify that WSDL service "Text" is correctly defined in the WSDL file.
</part>
</bindingFault>


Here is the definition of the callBackClient service in the .bpel file

<!-- Callback client asynchronously with response message -->
<invoke name="callbackClient"
partnerLink="client"
portType="tns:DemoCallback"
operation="onResult"
inputVariable="output"
/>

Here the entries in the .wsdl file related to this service, the porttype, message definition and the element (as part of the type definition)

<portType name="DemoCallback">
<operation name="onResult">
<input message="tns:DemoResponseMessage"/>
</operation>
</portType>


<message name="SNTDemoResponseMessage">
<part name="payload" element="tns:DemoResponse"/>
</message>

<element name="DemoResponse">
<complexType>
<sequence>
<element name="company" type="string" />
<element name="person" type="string" />
</sequence>
</complexType>
</element>

What could cause the error Failed to get WSDL service "Text" from WSDL definition?

Thanx in advance
Regards Leon Smiers

It seems to me that you want something like I show below. I am creating a JSON document from a random table (I chose one with a small number of columns, and I limited the row count to 4 to keep the output to a manageable size). The key name ROWSET is hardcoded, but the rest is automatic. Note the use of the wildcard * to stand for "all columns". This can also be used on a view rather than on a table. How you use it on a "cursor" (assuming you need one) I will let you figure out.
Check the documentation for the specific way in which Oracle converts data types from SQL to JSON.
Tested on Oracle 19 on LiveSQL.oracle.com; I only have 12.2 on my machine (on which this obviously fails).

select json_object(key 'ROWSET' value json_arrayagg(json_object(t.*))) as json_str
from   hr.countries t
where  rownum <= 4
;


JSON_STR
---------------------------------
{
"ROWSET" : [
{
"COUNTRY_ID" : "AR",
"COUNTRY_NAME" : "Argentina",
"REGION_ID" : 2
},
{
"COUNTRY_ID" : "AU",
"COUNTRY_NAME" : "Australia",
"REGION_ID" : 3
},
{
"COUNTRY_ID" : "BE",
"COUNTRY_NAME" : "Belgium",
"REGION_ID" : 1
},
{
"COUNTRY_ID" : "BR",
"COUNTRY_NAME" : "Brazil",
"REGION_ID" : 2
}
]
}

I don't understand the question. The LiveSQL example produces output with data, whereas you seem to be asking for output that describes the columns. Which is it?

A similar question was asked here:
Is it possible to use JSON SQL functions on a weak ref cursor rather than a table - Ask TOM (0 Bytes)There were two answers:

  1. APEX_JSON
  2. Use native JSON support in Oracle SQL, which requires changing the REF CURSOR itself, or else replacing the REF CURSOR by a named subquery and using a SQL table macro.
    Another approach would be to roll your own generic function: convert the REF CURSOR to a DBMS_SQL cursor, then generate whatever JSON you want.

It looks like APEX_JSON is the tool I'm looking for.
Thanks to both of you.

Oh ... Interesting find:
The APEX_JSON trick works on LONG data types (read Data Dictionary)
