Hi,

I noticed the resolve* operations documentation refers the usage of a trace.
I presume these features are only available if you QVTO is configured to
generated a trace log (i.e. it does not have some in memory trace buffer
some where). If the previous statement is correct it would imply these
functions are not available when QVTO is called from Java because there is
currently no way to configure tracing for standalone Java execution.

I would appreciate if someone could confirm the above statement since the
resolve* operations are certainly useful for complex transformations.

Thanks,
Derek

Hi Derek,

The resolve* feature must always work so the traces are kept in memory
during every transformation execution.
The only difference is that if you enable log file generation in QVTO
launch
configuration, the in-memory trace model is persisted.

IOW, traces are involved if a transformation is executed programmatically
using Java API too. There is no need to configure anything about traces to
have resolve* expressions work.
