Hello list,
I'm writing a webcrawler and using apache tika to extract text out of
certain mime-types.
what i'm actually doing right now is:
while(toVisit.size()){
[... SOME CODE HANDLING LISTS AND HTTPCLIENT ...]
client.executeMethod(method);
// just i.e. returns "text/html" or "application/pdf"
String mime = getContentType(method);
// extract text where possible and send it to the index
if(supportedContentType.contains(mime))
pool.execute(new MyContentHandler(new
CrawledResult(method.getResponseBodyAsStream(), workingURL, null, mime)));
else {
String htmlBody = method.getResponseBodyAsString();
}
[... SOME CODE TO EXTRACT LINKS OUT OF htmlBody AND
POPULATE toVisit SET ...]
method.releaseConnection();
}
My problem is that before my Threads can access the content of the
Stream, the crawler is calling the releaseConnection() which leads to an
IO Exception.
I'd like to avoid passing the whole HttpMethod and delegating its
management to my other Classes which should just know about IO Streams.
Do you have any idea on how i could handle this concurrency problem?
Maybe some cloning?
TIA
/CM
