Object Transformer serialize problem

[Paulo Carvalho]

Hello

I have a Java application which has a little method to serialize a javax.xml.transform.Transformer into a byte[].

Here is the method:

  

...
Object obj = transformer;
ByteArrayOutputStream bos = new ByteArrayOutputStream() ;
ObjectOutput out = new ObjectOutputStream(bos);
out.writeObject(obj);
out.close();

// Get the bytes of the serialized object
byte[] buf = bos.toByteArray();

...

However, I am getting the following error:

java.io.NotSerializableException: net.sf.saxon.Controller
at java.io.ObjectOutputStream.writeObject0(Unknown Source)
at java.io.ObjectOutputStream.writeObject(Unknown Source)
at .processing.transform.cache.CacheTransformers.addTransformer(CacheTransformers.java:62)
....

How can I solve the problem? Is there any other way to serialize a javax.xml.transform.Transformer object?

Thanks
Regards
