Description

When running the following piece of code:
Transformer identity = TransformerFactory.newInstance().newTransformer();
identity.setOutputProperty("method", "xml");
identity.setOutputProperty("indent", "yes");
identity.transform(src, new StreamResult(new File("file.xml")));

on a Sun JRE 1.5.0 or above, Xalan is unable to create a new file and thus throws a TransformerException.

This is caused by lines 225-235 in Xalan's TransformerIdentityImpl.java:
String fileURL = sresult.getSystemId();

if (fileURL.startsWith("file:///"))
{
if (fileURL.substring(8).indexOf(":") >0)
fileURL = fileURL.substring(8);
else
fileURL = fileURL.substring(7);
}

m_outputStream = new java.io.FileOutputStream(fileURL);

As of JRE 1.5.0 Sun now generates URIs in a different way in StreamResult (see StreamResult.setSystemId()), an therefore the URI will start with file:/ instead of file:///. Thus FileOutputStream will not be able to open the file anymore, since the if-block never executes.

The suggested fix is to change the code to the following:
String fileURL = sresult.getSystemId();

File file = new File(new URI(fileURL));
m_outputStream = new java.io.FileOutputStream(file);
