Subject Lazy loading error in Extracting request handler
Date Tue, 19 Apr 2011 06:47:10 GMT
Hi,

I am new to Solr and its configuration. I need to index some pdf files and
for that reason I thought of using the extractingrequesthandler.

I use Apache tomcat and run solr from it. 

I used the following command to index a pdf file.

 

C:\Users\vikky\Downloads\curl-7.21.0-win64-nossl>curl.exe
"http://localhost:8983/solr/update/extract?literal.id=doc4&uprefix=attr_&fma
p.content=attr_content&commit=true" -F
myfile=@G:\Official\Archiving\apache-solr-1.4.1\apache-solr-1.4.1\docs\featu
res.pdf

 

But, I got the following error. 

 

<html><head><title>Apache Tomcat/6.0.32 - Error report</title><style><!--H1
