PL/SQL Web Service Error: IllegalArgumentException : No Deserializer found

Question

I deployed a pl/sql web service on a stand-alone OC4J, when I test this I am getting error "IllegalArgumentException : No Deserializer found to deserialize". Find below the detailed response:
<?xml version="1.0" encoding="UTF-8" ?>
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
- <SOAP-ENV:Body>
- <SOAP-ENV:Fault>
<faultcode>SOAP-ENV:Server.Exception:</faultcode>
<faultstring>java.lang.IllegalArgumentException: No Deserializer found to deserialize a 'http://cmem.oracle.apps.cs.ws/ICmem_cs_ws_pkg.xsd:cmem_oracle_apps_cs_ws_CmemServiceRequestParamObj' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.</faultstring>
<faultactor>/cmemws/CmemServiceRequests</faultactor>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I was using a complex parameter as well as response. Below is the WSDL. If anyone has any idea what could be the issue, let me know.

Appreciate any help. Thanks.

Ok, this sounds like a known bug ( Bug 5908689 ) in 10.1.3.1, but this was specific to non-Windows platforms. Are you on Linux/Solaris or any other platform? It might or might not be the same problem you are hitting but it does seem quite close (can't say for sure without a close investigation, I am afraid!)
In any case, this bug is fixed in the 10.1.3.4 patchset (besides quite a few other fixes and enhancements) - so would recommend you to first apply the 10.1.3.4 patchset and retest. The patchset is available on My Oracle Support (formerly Metalink) under Patch 7272722. Or you could go a step ahead, and apply the 10.1.3.5 patchset (Patch 8626084) instead which is the latest patchset for OracleAS 10.1.3.x.
