error when using solr and Integrating nutch and solr(HTTP ERROR 500)
===

I have Linux Ubuntu 12.04 installed and I'm trying to install nutch 1.5.1 and solr 3.6.1 and integrate theme together to crawl seed urls.  
I'm using [This][1] tutorial to get this work.  
I followed the steps before 3.2 and skipped to [step 4][2] and I can access to  
localhost:8983/solr/admin/  

without error.  
but when going to step 6 and copying schema.xml from conf folder of nutch to example/solr/conf folder of solr
solr/admin page occurs a java error,below:

![first part of page][3]
![second part][4]

How can I handle that?
  
one more thing to ask....
I have another [tutorial][5] for this that looks good but in first step it mentions that add some code to nutch-site.xml file in /conf/ and /runtime/local/conf/ folder 
  
but in nutch folder there is no runtime folder.In step 4 this folder mentioned too.
any suggestion?  

thanks in advance
