Re: [xsl] xalan-j2 D7: StreamSource cannot be kept?

["Robert Koberg" <rob@xxxxxxxxxx>]

Ahh... OK, is there some way to make a copy to preserve the original? I have
tried to clone the object holding the StreamSource, like so:

public Object clone() {
      SiteManager site = null;
      try {
         site = (SiteManager) super.clone();
      } catch (CloneNotSupportedException e) {}
      return site;
   }

It works with a clone the first time, but fails to create any other clones.

Any ideas on how to workaround this?
