Errors when implementing VelocityResponseWriter 

Hello List,

I am currently trying to implement the above in Solr 1.4.1. Having moved velocity directory from $SOLR_DIST/contrib/velocity/src/main/solr/conf to my webapp /lib directory, then adding queryResponseWriter name="blah" and class="blah" followed by the responseHandler specifics I am shown the following terminal output. I also added <lib dir="./lib" /> in solrconfig. Can anyone suggest what I have not included in the config that is still required?

Thanks Lewis

RE: Errors when implementing VelocityResponseWriter

Posted by "McGibbney, Lewis John" <Le...@gcu.ac.uk>.
To add to this (which stupidly, I have not mentioned previously) I am using Tomcat 7.0.8 as my servlet container. I have a sneaking suspicion that this is what is causing the problem, but as per below, I am unsure as to a solution.

Hi Erik thank you for the reply

I have placed all velocity jar files in my /lib directory. As explained below, I have added relevant configuration to solrconfig.xml, I am just wondering if the config instructions in the wiki are missing something? Can anyone advise on this.

As you mentioned, my terminal output suggests that the VelocityResponseWriter class is not present and therefore the velocity jar is not present... however this is not the case.

I have specified <lib dir="./lib" /> in solrconfig.xml, is this enough or do I need to use an exact path. I have already tried specifying an exact path and it does not seem to work either.

Thank you

Lewis

looks like you're missing the Velocity JAR.  It needs to be in some Solr visible lib directory.  With 1.4.1 you'll need to put it in <solr-home>/lib.  In later versions, you can use the <lib> elements in solrconfig.xml to point to other directories.

RE: Errors when implementing VelocityResponseWriter

Posted by "McGibbney, Lewis John" <Le...@gcu.ac.uk>.
Managed to get this working. Changed my solrconfig for the one provided in velocity dir, repackaged the war file and redeployed on tomcat.

Although this seems like a ridiculously obvious thing to do, I somehow overlooked the repackaging aspect, this was where the problem was.

Thanks for the help Erik

Well, you need to specify a path, relative or absolute, that points to the directory where the Velocity JAR file resides.

I'm not sure, at this point, exactly what you're missing.  But it should be fairly straightforward.  Solr startup logs the libraries it loads, so maybe that is helpful info.

1.4.1 - does it support <lib>?  (I'm not sure off the top of my head)

RE: Errors when implementing VelocityResponseWriter

Posted by "McGibbney, Lewis John" <Le...@gcu.ac.uk>.
Hi Erik thank you for the reply

I have placed all velocity jar files in my /lib directory. As explained below, I have added relevant configuration to solrconfig.xml, I am just wondering if the config instructions in the wiki are missing something? Can anyone advise on this.

As you mentioned, my terminal output suggests that the VelocityResponseWriter class is not present and therefore the velocity jar is not present... however this is not the case.

I have specified <lib dir="./lib" /> in solrconfig.xml, is this enough or do I need to use an exact path. I have already tried specifying an exact path and it does not seem to work either.

Thank you

Lewis

looks like you're missing the Velocity JAR.  It needs to be in some Solr visible lib directory.  With 1.4.1 you'll need to put it in <solr-home>/lib.  In later versions, you can use the <lib> elements in solrconfig.xml to point to other directories.

Having moved velocity directory from $SOLR_DIST/contrib/velocity/src/main/solr/conf to my webapp /lib directory, then adding queryResponseWriter name="blah" and class="blah" followed by the responseHandler specifics I am shown the following terminal output. I also added <lib dir="./lib" /> in solrconfig. Can anyone suggest what I have not included in the config that is still required?
