I have been trying to modify the default search-and-result.xsp to suit my needs and have ran into a rather large problem. I keep on getting "org.apache.cocoon.ProcessingException: Error executing pipeline.: org.apache.cocoon.ProcessingException: Error executing pipeline.: org.apache.cocoon.ProcessingException: Failed to execute pipeline.: java.lang.NullPointerException " However, I'm quite sure that the pipeline is ok, since when I comment out the contents of my search-and-result.xsp file, things seem to work (I get a rather nicely formated, but 'body' empty page .. which is to be expected) When I look in my log4j.log file I see : 372823366 2005-06-21 16:56:48,819 [http-8080-Processor25] ERROR sitemap.handled-errors.prepareErrorHandler():165 - Error executing pipeline. org.apache.cocoon.ProcessingException: Error executing pipeline.: org.apache.cocoon.ProcessingException: Error executing pipeline.: org.apache.cocoon.ProcessingException: Failed to execute pipeline.: java.lang.NullPointerException Does this mean that my problem is my 'handle-errors' pipeline or does it mean that my problem is an exception which is thrown by my xsp ?Did you replace the usecase-search.xmap since the 16th? There was a bug in the pipelines. The paths to the search*.xsl files in usecase-search.xmap did not match the directory where the instructions said to place the files. I had moved them from {pub}/lenya/xslt/search/ to {pub}/xslt/search/. Make certain the paths are correct, or download the corrected usecase-search.xmap.
Yes, I've replaced/kept up with your suggested changes, and I am sure that my usecase-search.xmap is correct. I have got it 'working' before I started changing it. (as mentioned in tread [Re: Lucene: problem while crawling] mine did not display any hits).
I was not sure whether it is because my indexing is wrong(There are some index files where they should be .. but how do I know whether they are right or not?)
Or it could be that the file you posted is bad. The file displayed as garbage on my system. It should be text. What did you use to edit it? Try using the download.
The file I posted was edited using vim(I copied your one, and then made some changes). I have 'imported' it to my windows environment and attached it again, the tabbing is bound to be messed up ... sorry :/.
