How do I read files inside an Action?
Hi,
Can some one point me to an example of how we can access an xml file on the file system from a custom Action?
TIA,
Sreedhar

You can do it like this:
Source source = null;
SourceResolver resolver = null;
try {
resolver = (SourceResolver) manager.lookup(
SourceResolver.ROLE );
source = resolver.resolveURI( fileName );
return builder.parse( new InputSource(
source.getInputStream() ));
}
catch (Exception x) {
logger.warn("XMLREsourceBundle: No excalibur-source " +
fileName,
x);
}
finally {
resolver.release( source );
manager.release( resolver );
}
Take a look at the ResourceExistsAction or latest (from CVS)
XMLResourceBundle for details.

Sir,
Just like any other file called from java.
In the action class you would need:
import java.io.File; // cocoon has some defaults - this could be one of them
//nothing special here, just an example. however, this directory is where
cocoon places uploaded files by default. make yours wherever your xml file
is located.
String currentPath = "C:/Program Files/Apache Group/Tomcat
4.1/work/Standalone/localhost/cocoon/cocoon-files/upload-dir/";
// next three lines checks the directory for files and sets pointer to the
first file in the directory (should put some checks around this)(could
iterate through the list)
File fileDir = new File(currentPath);
File[] listOfFiles = fileDir.listFiles();
String filename = listOfFiles[0].toString();
File uploadDir = new File(currentPath);
File theXMLfile = new File(filename);
System.out.println("The director is: " + theResume.getParent());
System.out.println("The file name: " + theResume.getName());
long fileLen = theXMLfile.length();
Long testThis = new Long(fileLen);
int fileLength = testThis.intValue();
FileInputStream fis = new FileInputStream(theResume);
byte[] byteArray = new byte[fileLength];
int cnt = fis.read(byteArray, 0, fileLength);
fis.close();
byteArray now contains the contents of theXMLfile. this only works for
ASCII files. i do not have an example at my fingertips for Unicode.
these are snippets from an action that i have performing. if you need
anything else, holler.
