in plugin/parse-tika I replaced parse-tika.jar and tika-parsers-0.7.jar
with tika-core-0.8-SNAPSHOT.jar and tika-parsers-0.8-SNAPSHOT.jar
in lib/ I replaced tika-core-0.7.jar with tika-core-0.8-SNAPSHOT.jar
I ran bin/nutch crawl and it completed w/o error. All of the javascript
was fetched and appeared to be parsed w/o error. However, and I'm not
sure the correct terminology to use, no more urls were generated to
fetch than before. So the patch appears to be a step in the right
direction. The problem is with the FRAMESET/FRAME and how javascript is
used to generate content in the FRAMES.
As Julien suggested, I will read the archive deeper and look at the
legacy parse-js. I suppose as a really ugly 'brute force' work around I
could walk the directory tree w/ a perl script and generate a 'seed
list' of html URLs to fetch. Ugh. If you have any more ideas please let
me know how I can help. Thanks.

Re: nutch crawl issue
Hi Matthew, As you can see from the error messages Tika does not know how to parse javascript. There is a legacy javascript parser in Nutch which you can activate in the usual way i.e. specify parse-js in plugin.includes. It generates a lot of spurious URLs but you should give it a try and see if it gives you the outlinks you expect. I think there have been quite a few discussions about javascript processing in the nutch archives. BTW a good practice is to separate the fetching from the parsing step, so that if the parsing fails you won't need to refetch the URLs. That can be done of you call the fetch and parse commands (and not the all-in-one crawl command) and specify -noparse while fetching.

Re: nutch crawl issue
Hi Matthew, I think Julien may have a fix for this in TIKA-379 [1]. I’ll take a look at Julien’s patch and see if there is a way to get it committed sooner rather than later. One way to help me do that ― since you already have an environment and set of use cases where this is reproduceable can you apply TIKA-379 to a local checkout of tika trunk (I’ll show you how) and then let me know if that fixes parse-tika for you? Here are the steps: svn co http://svn.apache.org/repos/asf/lucene/tika/trunk ./tika cd tika wget "http://bit.ly/bXeLkf"; (if you don't have SSL support, then manually download the linked file) patch -p0 < TIKA-379-3.patch mvn install package Then grab tika-parsers and tika-core out of the respective tika-core/target and tika-parsers/target directories and drop those jars in your parse-tika/lib folder, replacing their originals. Then, try your nutch crawl again. See if that works. In the meanwhile, I'll inspect Julien's patch. Thanks!

Hi Chris, It appears to me that parse-tika has trouble with HTML FRAMESETS/FRAMES and/or javascript.

Re: nutch crawl issue
Hi Matthew, There is an open issue with Tika (e.g. https://issues.apache.org/jira/browse/TIKA-379) that could explain the differences betwen parse-html and parse-tika. Note that you can specify : *parse-(html|pdf) *in order to get both HTML and PDF files. Could you please open an issue in JIRA https://issues.apache.org/jira/browse/NUTCH) and attach the file you are trying to process? I'll have a look and see if it is related to TIKA-379.

Re: nutch crawl issue
in nutch-site.xml I modified plugin.includes parse-(html) works parse-(tika) does not I need to also parse pdfs so I need both features, I tried parse-(html| tika) to see if html would be selected before tika and that did not work.

Re: nutch crawl issue
My subject should've been clearer, e.g. it should've read Nutch 1.1 nightly build crawl issue. Also, I did verify that Nutch 1.0 successfully completes crawling the javadoc html file and can be verified with luke-1.0.1 and searched using command line bin/nutch org.apache.nutch.searcher.NutchBean java On Wed, 2010-04-28 at 00:39 -0400, matthew a. grisius wrote: > using Nutch nightly build nutch-2010-04-27_04-00-28: > > I am trying to bin/nutch crawl a single html file generated by javadoc > and no links are followed.
