Solr 4.3, Tomcat, Error filterStart
I am trying to get Solr installed in Tomcat, and having trouble. I am trying to use the instructions at http://wiki.apache.org/solr/SolrTomcat as a guide. Trying to start with the example Solr from the Solr distro. Tried using the Tried with both a binary distro with existing solr.war, and with compiling my own solr.war. * Solr 4.3.0 * Tomcat 6.0.29 * JVM 1.6 When I start up tomcat, I get in the Tomcat log: INFO: Deploying web application archive solr.war May 29, 2013 3:59:40 PM org.apache.catalina.core.StandardContext start SEVERE: Error filterStart May 29, 2013 3:59:40 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/solr] startup failed due to previous errors And solr is not actually deployed, naturally. I've tried to google for advice on this -- mostly what I found was suggestions for how to turn up logging to get more info (maybe a stack trace?) to give you more clues what's failing -- but nothing I found suggested succesfully worked to turn up logging. So I'm at a bit of a loss. Any suggestions? Any ideas what might be causing this error, and/or how to get more information on what's causing it?

Re: Solr 4.3, Tomcat, Error filterStart
Usually tomcat errors with Solr 4.3 happen due to uncopied logging libraries. I would check if installing Solr 4.2.1 works and/or copy additional libraries in (search mailing list for this issue). However, I am not entirely sure that's the case here. It feels that perhaps the definition of the handler could be a bigger issue here. I assume you have an xml file somewhere that defines that /solr maps to solr.war. I would double check that. Maybe try to deploy something smaller and easier and see what the difference is.

Re: Solr 4.3, Tomcat, Error filterStart
Thanks! I guess I should have asked on-list BEFORE wasting 4 hours fighting with it myself, but I was trying to be a good user and do my homework! Oh well. Off to the logging instructions, hope I can figure them out -- if you could update the tomcat instructions with the simplest possible way to get deploy in Tomcat to work, that'd def be helpful!

Re: Solr 4.3, Tomcat, Error filterStart
I'm going to add a note to http://wiki.apache.org/solr/SolrLogging , with the Tomcat sample Error filterStart error, as an example of something you might see if you have not set up logging. Then at least in the future, googling solr tomcat error filterStart might lead someone to the clue that it might be logging.

Commute done. I'm not a tomcat user, so the only thing I know about where to drop those jars and properties file is tomcat/lib ... do you have anything more specific that I can include in the wiki page? In particular, I'd like to know if there are any particular config files or other specific information I can list to help the reader locate where tomcat/lib lives. I suppose I can put what I do know and let someone with better knowledge update it. Thanks, Shawn
Re: Solr 4.3, Tomcat, Error filterStart
Okay, sadly, i still can't get this to work. Following the instructions at: https://wiki.apache.org/solr/SolrLogging#Using_the_example_logging_setup_in_containers_other_than_Jetty I copied solr/example/lib/ext/*.jar into my tomcat's ./lib, and copied solr/example/resources/log4j.properties there too. The result is unchanged, when I start tomcat, it still says: May 30, 2013 3:15:00 PM org.apache.catalina.core.StandardContext start SEVERE: Error filterStart May 30, 2013 3:15:00 PM org.apache.catalina.core.StandardContext start SEVERE: Context [/solr] startup failed due to previous errors This is very frustrating. I have no way to even be sure this problem really is logging related, although it seems likely. But I feel like I'm just randomly moving chairs around and hoping the error will go away, and it does not. Is there anyone that has succesfully run Solr 4.3.0 in a Tomcat 6? Can we even confirm this is possible? Can anyone give me any other hints, especially does anyone have any idea how to get some more logging out of Tomcat, then the fairly useless Error filterSTart? The only reason I'm using tomcat is that we always have in our current Solr 1.4-based application, for reasons lost to time. I was hoping to upgrade to Solr 4.3, without simultaneously switching our infrastructure from tomcat to jetty, change one thing at a time. I suppose I might need to abandon that and switch to jetty too, but I'd rather not.

You might need to edit the log4j.properties file so that it points at a location that exists - the default is logs/solr.log, relative to the current working directory of the tomcat process. Once the log4j destination gets created properly, you can look there for Solr's logs, which will hopefully give you additional insight. If you want it to work with tomcat exactly how it did before, then you can go back to the old logging method (java.util.logging) with another section on that page: http://wiki.apache.org/solr/SolrLogging#Switching_from_Log4J_back_to_JUL_.28java.util.logging.29 Thanks, Shawn
Re: Solr 4.3, Tomcat, Error filterStart
Okay, for posterity: I did manage to get it working. It WAS lack of the logging files. First, the only way I could manage to get Tomcat6 to log an actual stacktrace for the Error filterStart was to _delete_ my CATALINA_HOME/conf/logging.properties file. Apparently without this file at all, the default ends up being 'log everything'. And once that happened, it did confirm that the Error filterStart problem WAS an inability to find the logging jars. (And the stack trace was an exception from Solr with a nice message including the URL to the logging wiki page, nice one solr). Nothing I tried before in a fit of desperation deleting that file entirely worked to get the stack trace logged. Once confirmed that the problem really was not finding the logging jars, I could keep doing things and restarting and seeing if that was still the exception. And I found that for some reason, despite http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html suggesting that jars could be found in either CATALINA_BASE/lib (for me /opt/tomcat6/lib), OR CATALINA_BASE/lib (for me /usr/share/tomcat6/lib), in fact for whatever reason /opt/tomcat6/lib was being ignored, but /usr/share/tomcat6/lib worked. And now I succesfully have solr started in tomcat. I realize that these are all tomcat6 issues, not solr issues. But others trying to get solr started may have similar problems. Appreciate the tip that the Error filterStart was probably related to new solr 4.3.0 logging setup, which ended up confirmed.
