Brian Minchau updated XALANJ-1462:
----------------------------------
Version: Latest Development Code
(was: 2.3)
> Using an InputStream with "getAssociatedStylesheet()" causes IOException
> ------------------------------------------------------------------------
>
> Key: XALANJ-1462
> URL: http://issues.apache.org/jira/browse/XALANJ-1462
> Project: XalanJ2
> Type: Bug
> Components: transformation, Xalan-interpretive
> Versions: Latest Development Code
> Environment: Operating System: All
> Platform: PC
> Reporter: Gerard Fernandes
> Assignee: Xalan Developers Mailing List
>
> Using an InputStream as the Source XML along with "getAssociatedStylesheet()"
> causes the transformation to fail with an IOException due to Stream closed.
> This probably happens because the "getAssociatedStylesheet()" method causes
> the
> stream to be closed at the end. This happens because the Xerces SAX Parser
> Implementation seems to be closing the InputStream passed to it for parsing
> (which may be good in some cases, but can cause problems when used in the
> following manner).
> The subsequent call to "transform(source, result)" therefore acts on a closed
> source stream and throws the IOException.
> Sample code:
> ------------
> public void transform(InputStream source, OutputStream result)
> {
> Source style = TransformerFactory.newInstance().getAssociatedStylesheet(
> source, null, null, null);
> Transformer t = TransformerFactory.newInstance().newTransformer();
> if(style != null){
> t = TransformerFactory.newInstance().newTransformer(style);
> }
> t.transform(new StreamSource(source), new StreamResult(result));
> }
> Exception:
> ----------
