Hi: it seems you are writing to a xml file with multiple threads. I guess it can be done by using BlockingQueue in java 1.5 concurrency api. you just add any url entry into the queue from multiple producer threads, and use a separate consumer thread to retrive url entries from the queue and write to a single file in append mode. I see that Fetcher use multiple FetcherThread to fetch pages so I guess this trick would work.
