Parsing Java Stack AAE Data

73 Views

Hi,

I am able to extract AAE logs from the Java stack.

I am facing problems in parsing this data.

Manual observation reveals the main logs, but I get a lot of junk (non displayable characters also).

The field in question is AUDIT_DATA from BC_MSG_AUDIT (PI 7.1)

I am reading the blob data as UTF-8 string via InputStreamReader.

I have added a function to strip the string from invalid XML characters (as i am returning data via a web service).

I am pasting a sample output:

ï¿½ï¿½ur9[Lcom.sap.engine.messaging.impl.util.auditlog.AuditEntry;ï¿½U7tï¿½(xpsr6com.sap.engine.messaging.impl.util.auditlog.AuditEntry*Z

As u can see, most of the main error messages are there, but why all the junk characters??

Cheers,
