Re: [xsl] Xalan-J 2 and getParameter(...) method returns null???

[Johannes Döbler <jd at aztecrider dot com>]

from the Trax documentation:

public abstract java.lang.Object getParameter(java.lang.String name)
     Get a parameter that was explicitly set with setParameter or 
setParameters.
     This method does not return a default parameter value, which cannot 
be determined until the node context is evaluated during the transformation
     process.
     Returns:
          A parameter that has been set with setParameter.

Cheers,
Johannes
