Exception when serialization a Exception class to JSON

Hi,

at rtgov activity logging i need to serializate an Exception object to JSON. But become exception below. Simulation of Exception is very easy: ActivityUtil.objectToJSONString(new Exception());

What to do now?

[org.overlord.rtgov.activity.processor.SerializeInformationTransformer] Failed to transformer information 'javax.xml.soap.SOAPException: This is an operation implementation generated fault' to JSON: org.codehaus.jackson.map.JsonMappingException: Class java.lang.StackTraceElement has no default constructor; can not instantiate default bean value to support 'properties=JsonSerialize.Inclusion.NON_DEFAULT' annotation (through reference chain: javax.xml.soap.SOAPException["stackTrace"])

Hi Pavel

The 'serialize' transformer can only be used where it is possible to use the default JSON serialization. However, as you have found out, it is not possible to serialize exceptions.

Therefore, the only other transformer implementation currently available is the 'mvel' one (see Chapter 4. Reporting Activity Information). So you can use this to define how to extract the information you require from the exception.
