HI everybody,
I'm using the file poller to read a file from the file system and then send
the content of the file to a servicemix-bean component. There I want to do
something with the file content an then send to a topic.
So this is the code inside the servicemix-bean component.
public void onMessageExchange(MessageExchange exchange) {
String strFileContent=readStream(exchange);
... doSomething with the content
...send to Topic
}
private String readStream(MessageExchange exchange) {
Source source = exchange.getMessage("in").getContent();
StreamSource ssource = null;
InputStream stream = null;
String strFileContent = "";
if (source instanceof StreamSource) {
ssource = (StreamSource) source;
}
if (ssource != null) {
stream = ssource.getInputStream();
byte buffer[] = new byte[10000];
int len = 0;
try {
len = stream.read(buffer, 0, 4000);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
strFileContent = new String(buffer, 0, len);
return strFileContent;
}
return null;
}
The problem is that I get the following exception:
java.io.IOException: Stream closed

So I have the problem, that I do not get the content of the file. Has
someone a solution for this problem?
