Resin 2.0.5 vs Resin 2.1.X XSLT diff?

[asaguden]

Hi,
We have a production env with Resin 2.0.5 and
a development end with Resin 2.1.X.

Xslt cmd '<xsl:import href="common/general.xsl"/>' in file.xsl
works fine in Resin 2.1.X with
Java imports:
import javax.xml.transform.Transformer;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

and transform code:
Transformer xsl = getTransform( "file.xsl" );
xsl.transform( new StreamSource( new StringReader( obj.toXML() ) ),
new StreamResult( res.getOutputStream() ) );

BUT same code in Resin 2.0.5 throws:
java.io.IOException: javax.xml.transform.TransformerException:
javax.xml.transform.TransformerException:
"<swe>Fick IO-Undantag med stylesheet-fil</swe>: common/general.xsl

What is the XSL difference between the two releases?
