I use Saxon Transformer Transformerfactory.newInstance().newTransformer() for
transforming DomSource to Writer.
My Question is :
Can I make the TransformerFactory static so that only one Factory creates
Transformers for different threads ?
It should be perfectly safe to use a TransformerFactory concurrently in
different threads, provided of course that you don't try setting its
properties such as the ErrorListener and URIResolver.
However, I'm not sure it's wise to make it static. Underneath the Saxon
TransformerFactory is the Saxon Configuration, and this owns all kinds of
resources like loaded schemas, the namepool, and so on. While it's fine to
share these across threads in a single application, at some point you may want
to run multiple applications concurrently within the same JVM, and you will
want to have the flexibility to unload these resources when the application
finishes, or to have different schemas and namepools in different
