Implemented OWSM -- XML-22045: (Error) Extension function error

Question

good day
When I activated my OWSMAgent within ESB, I launched a null pointer Exception when running a fault, since I have reviewed the documentation WSM_DeploymentGuide and commented that it is not possible to add an error handler general, reviewing the logs I found the following error:
XML-22045: (Error) Extension function error: Class not found '
Missing class: com.cablemas.extensionfunctioncablemas.ExtensionFunctionCablemas
Dependent class: oracle.xml.xpath.XSLExtFunctions
Loader: oracle.xml: 10.1.0_2
Code-Source: / F: / product/10.1.3.1/OracleAS_1/lib/xmlparserv2.jar
Configuration: <code-source> (ignore manifest Class-Path) in META-INF/boot.xml in F: \ product \ 10.1.3.1 \ OracleAS_1 \ j2ee \ home \ oc4j.jar
This load was initiated at oc4j: 10.1.3 using the loadClass () method.
The missing class is available from the following locations:
1. Code-Source: / F: / product/10.1.3.1/OracleAS_1/j2ee/oc4j_soa/applib/ExtensionFunctionCablemas.jar (from <code-source> in / F: / product/10.1.3.1/OracleAS_1/j2ee/oc4j_soa/config / server.xml)
This source code is available in loader global.libraries: 1.0. This shared-library can be made visible to the "oc4j" by modifying the boot loader descriptor.
Class ExtensionFunctionCablemas use it to take the code of the error, locate it within a table in the DB and return the corresponding message, the null pointer exception only if it throws error. OWSM reviewing the request is recorded correctly, and the answer recorded as a fault but I'm not returning the message corresponding to error code.

Greetings,
Quoted:
When using Oracle XSLT extensions, make sure you set the namespace of the extension class to be:
http://www.oracle.com/XSL/Transform/java/This was excerpted from the pdf at:
