Re: Nutch and Google Map togather for Real Estate search.
Yeah, I see it too. At http://www.realestateadvisor.com/search.jsp a url that I entered , not linked off of, I see an invalid page with Nutch java exceptions: root cause java.lang.NullPointerException at org.apache.nutch.searcher.NutchBean.init(NutchBean.java:96) at org.apache.nutch.searcher.NutchBean.(NutchBean.java:82) Diane Palla Web Services Developer Seton Hall University 973 313-6199 [EMAIL PROTECTED] Benny Krauss <[EMAIL PROTECTED]> 12/07/2005 11:42 AM Please respond to nutch-user@lucene.apache.org To nutch-user@lucene.apache.org cc Subject Re: Nutch and Google Map togather for Real Estate search.

PDF support? Does crawl parse p
Does Nutch have a way to parse pdf files, that is, "application/pdf" content type files? I noticed a plugin variable setting in default.properties: plugin.pdf=org.apache.nutch.parse.pdf* I never changed this file. Is that the right value? I am using Nutch 0.7. What do I have to do make parse pdf files? When I do the crawl, I get this error with application/pdf files: 050831 145126 fetch okay, but can't parse /research/126900/126969/126969.pdf, reason: failed(2,203): Content-Type not text/html: application/pdf If it's not possible, what future version of Nutch do developers expect to support application/pdf types and have such parsing of pdf files available?

Re: Search Java JSP error after configuration and set up. Please help.
ok I entered /usr/local/jakarta-tomcat-4.1.31/bin/catalina.sh start when i was in the crawl.test directory. The search.jsp works now without reporting JSP/Java errors and stack traces. Thanks. What do you mean that I must "(...have it configured in nutch-default.xml in *.war file)" in order to start tomcat without being in crawl.test directory to have it the searches work on http://localhost:8080? What properties do I have to set in this file nutch-default.xml to make that work?

I am trying to set up Nutch with an intranet. I used Nutch 0.7 with Java J2SE 1.4.2 and Tomcat 4.1.31. I did the crawl with the command bin/nutch crawl bin/urls.txt -dir crawl.test -depth 3 >& crawl.log and the crawl.log gave log messages that appeared to imply that it was a successful run. (Crawl.log is copied after the Java/JSP errors below) and I set JAVA_HOME and NUTCH_JAVA_HOME to the J2re when I did the crawl, but I set JAVA_HOME to the j2se when I ran tomcat and i went to http://localhost:8080 I tried to search something and I got this error of the Nutch Bean.
