hi Andrzej: Currently, I implemented Nutch 61 in Nutch version 07.
http://issues.apache.org/jira/browse/NUTCH-61 Compiling is successfully. I create an empty DB, insert urls, so far so good; But, when I run bin/nutch/generate (segments) command, I got the following error: Note the line number might be shift a bit coz I change the code according to Nutch61 diff file. " 050910 111335 Overall processing: Sorted 0 entries in 0.0 seconds. 050910 111335 Overall processing: Sorted NaN entries/second Exception in thread "main" java.lang.NullPointerException at org.apache.nutch.tools.FetchListTool.emitFetchList(FetchListTool.java:488) at org.apache.nutch.tools.FetchListTool.emitFetchList(FetchListTool.java:319) at org.apache.nutch.tools.FetchListTool.main(FetchListTool.java:612) " And I took look at FetchListTool.java, and focus on the following piece of new code of Nutch61: " FetchListEntry value = new FetchListEntry(); Page page = (Page)value.getPage().clone(); " Seems value is an empty FetchListEntry instance. Will that cause clone getPage failure coz it is NULL? thanks, Michael Ji ______________________________________________________ Click here to donate to the Hurricane Katrina relief effort. http://store.yahoo.com/redcross-donate3/ ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Nutch-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/nutch-developers
