After having investigated a bit, I discovered that the guilty for leaving the file
opened is a CopySourceAction invokation, that tries to get the result of the previous
pipeline, through the cocoon:// protocol.
The following code from org.apache.cocoon.acting.CopySourceAction leaves the stream
opened:
public void service(ServiceManager manager) throws ServiceException {
super.service(manager);
this.resolver = (SourceResolver)manager.lookup(SourceResolver.ROLE);
}
public Map act(Redirector redirector, SourceResolver oldResolver, Map objectModel, String source, Parameters par)
Source src = resolver.resolveURI(source);
Source dest = resolver.resolveURI(par.getParameter("dest"));
// Check that dest is writeable
if (! (dest instanceof ModifiableSource)) {
throw new IllegalArgumentException("Non-writeable URI : " + dest.getURI());
}
ModifiableSource wdest = (ModifiableSource)dest;
// Get streams
InputStream is = src.getInputStream(); <----Here the file is opened forever
OutputStream os = wdest.getOutputStream();
// And transfer all content.
try {
byte[] buffer = new byte[1024];
int len;
while ((len = is.read(buffer, 0, buffer.length)) > 0) {
os.write(buffer, 0, len);
}
os.close();
} catch(Exception e) {
if (wdest.canCancel(os)) {
wdest.cancel(os);
}
} finally {
is.close(); <------This does nothing, because the stream is a
ByteArrayStream
}
// Success !
return EMPTY_MAP;
Is this solved in later versions of Cocoon?
I don't actually know. But if you've narrowed it down to a particular
class, have a look using http://cvs.apache.org/viewcvs.cgi/cocoon-2.1 to
see if the code has changed. If not, you can always provide a patch.

Asunto: File remains open
Hi all,
I have the following pipeline:
<map:match pattern="genera/**.sxw">
<map:generate src="jar:file:///{realpath:docu}/{1}.sxw!/content.xml"/>
<map:transform label="t1" src="transf/open-office-a-docbook.xsl"/>
<map:serialize type="xml"/>
</map:match>
I have an exception inside the transformer.
The result is that the source document remains open (the *.sxw), and I can not replace it with 3rd party utilities.
I'm using Cocoon 2.0.3. Is this solved in newer Cocoon releases? Any workaround?
Thanks in advance for any help.
David
