SOAP Fault when returning null from a Native Web Service Stored Procedure

Question

I have a stored procedure which I can successfully invoke via soapUI
However, if one of the Stored Procedure's OUT arguments is set to null the native web service returns the following fault :
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
<faultstring>Error processing input</faultstring>
<detail>
<OracleErrors xmlns="http://xmlns.oracle.com/orawsv/faults">
<OracleError>
<ErrorNumber>ORA-19202</ErrorNumber>
<Message>Error occurred in XML processing</Message>
</OracleError>
<OracleError>
<ErrorNumber>ORA-01405</ErrorNumber>
<Message>fetched column value is NULL</Message>
</OracleError>
</OracleErrors>
</detail>
</soap:Fault>
</soap:Body>
</soap:Envelope>I can see how to control the processing of null values when invoking orawsv (using the null_handling element).
Is there an equivalent for Stored Procedures ?
Thanks,
PD

Answer 1

Without going into any technical discussion about the code, my first question is what JDK version was used to create this which was imported into the form? Understand that Forms 10 runs on JDK 1.4.2, so if you used any newer JDK version, likely there will be problems.
