Hope the following code helps....
IDocument doc = new Document(getText(file));
// getText() returns the contents of the file
public static String getText(IFile file) {
try {
InputStream in = file.getContents();
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buf = new byte[1024];
int read = in.read(buf);
while (read > 0) {
out.write(buf, 0, read);
read = in.read(buf);
}
return out.toString();
} catch (CoreException e) {
} catch (IOException e) {
}
return "";
}
