how to read full exception stack trace from errorChannel

I am trying to save the exception stack trace to database for some monitoring purpose and i have below configuration but it only prints first line of exception message not the entire stack trace, what i am doing wrong here?

<int-jdbc:stored-proc-outbound-gateway 
            id="errorDBLogger"
            data-source="dataSource"
            request-channel="errorChannel" 
            reply-channel="errorSaverepply"
            stored-procedure-name="some_SP "
            ignore-column-meta-data="true">             
            <int-jdbc:sql-parameter-definition .....parameter mappings..
            <int-jdbc:parameter name="errorMessage" expression="payload"/>                                                  
</int-jdbc:stored-proc-outbound-gateway>

Also i will like default error handling mechanism to remain unaffected as i also have logger configured to email errros which i want to keep as it is, if you could reply in that scenario please. Thanks

The payload is an Exception and Throwable.toString() only includes the class name and message.

You will need a transformer or header-enricher upstream to convert the payload to the stack trace.

EDIT:

To get the stack trace you have to invoke Throwable.printStackTrace(pw); by default, Throwable.printStackTreace() writes to stderr so you need to create a PrintWriter to pass in.

Something like...

private String getStackTraceAsString(Throwable cause) {
    StringWriter stringWriter = new StringWriter();
    PrintWriter printWriter = new PrintWriter(stringWriter, true);
    cause.printStackTrace(printWriter);
    return stringWriter.getBuffer().toString();
}
