Hi,
i am using the LevelDB repository of Camel to store exchange while
aggregating.
Every exchange contains a simple POJO in the header that serves as
aggregation predicate.
But Camel don't wont to serialize my class because:
WARN org.apache.camel.impl.DefaultExchangeHolder -- Exchange in headers
containing key: RECID with object: CEN-PRJ-22 of type: com.domain.ID is not
valid header type, it will be excluded by the holder.
I look into the DefaultExchangeHolder and this function seems to be the
problem:
protected static Object getValidHeaderValue(String headerName, Object
headerValue) {
Why does this class do a check with the default java types?
In the official documentation of LevelDB (
http://camel.apache.org/leveldb.html <http://camel.apache.org/leveldb.html>
) you can read:
LevelDBAggregationRepository will only preserve any Serializable compatible
data types. If a data type is not such a type its dropped and a WARN is
logged. And it only persists the Message body and the Message headers. The
Exchange properties are not persisted.
So my class got the signature:
public class ID implements Cloneable, Serializable {
and only 3 properties:
private final String org;
private final String type;
private String key;
So it should be possible to store/restore this as header field?
Did i miss something here?
Thanks in advance.
Best regards,
Hubertus Willuhn
