Threading Problem with Xalan 2.0.0

[Marinus Jansen <ma...@hotmail.com>]

Hi

The following bug fix in 2.0.D06 causes us some problems when using the 
Xalan Extensions with the Java Servlet API.

'Fixed some threading problems and improved support for handling Exceptions 
thrown in a secondary thread.

Note: To support incremental output, Xalan-Java performs the transformation 
in a second thread while building the source tree in the main thread.'

We are using a Xalan Extension that calls the Java Servlet API.

When our Xalan Extension is called and initialised it retrieves the Servlet 
Session information via the Servlet API.

In the Servlet API session information can be accessed - but only within the 
current thread.

The problem we have is that the Transformation (i.e. the initialisation of 
the Xalan Extension) is in A NEW THREAD which means the Servlet API doesn't 
find the session information (because it is in the original thread) which 
means our transformation fails.

Are there any plans to rectify the 'dual thread' processing of the 
transformation ?  Does the transformation have to be performed in a new 
thread to support incremental input/output ?

Any suggestions for a work around ?

Regards

Marinus Jansen
