Ubuntu 14.04
I installed using sudo apt-get install solr-tomcat.
It seems the "core" functionality was installed and is working, but not any Plugins (or I just don't know where to look).
I am trying to use the extract function, which is a Plugin.
When I attempt, I get this
org.apache.solr.common.SolrException: lazy loading error at org.apache.solr.core.RequestHandlers$LazyRequestHandlerWrapper.getWrappedHandler(RequestHandlers.java:260) at org.apache.solr.core.RequestHandlers$LazyRequestHandlerWrapper.handleRequest(RequestHandlers.java:242) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1376) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:365) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:260) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:861) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:606) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:745) Caused by: org.apache.solr.common.SolrException: Error loading class 'solr.extraction.ExtractingRequestHandler' at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:414) at org.apache.solr.core.SolrCore.createInstance(SolrCore.java:419) at org.apache.solr.core.SolrCore.createRequestHandler(SolrCore.java:455) at org.apache.solr.core.RequestHandlers$LazyRequestHandlerWrapper.getWrappedHandler(RequestHandlers.java:251) ... 16 more Caused by: java.lang.ClassNotFoundException: solr.extraction.ExtractingRequestHandler at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at java.net.FactoryURLClassLoader.loadClass(URLClassLoader.java:789) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:274) at org.apache.solr.core.SolrResourceLoader.findClass(SolrResourceLoader.java:398) ... 19 more
I manually downloaded the latest version just to investigate, and did find an "extraction" directory, and, within, a file called ExtractingRequestHandler.java.
I'm not a Java guy. I looked for a similar path to what the error indicated and found "/usr/share/maven-repo/org/apache/solr/solr-core", which does not strictly correspond with "org.apache.solr.core". So, I'm hesitant to assume anything here.
Solr is searching for the "extraction" directory - I'm just not sure where.
My solrconfig.xml file has this
<requestHandler name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
<!-- All the main content goes into "text"... if you need to return
the extracted text or do highlighting, use a stored field. -->
<str name="fmap.content">text</str>
<str name="lowernames">true</str>
<str name="uprefix">ignored_</str>
<!-- capture link hrefs but ignore div attributes -->
<str name="captureAttr">true</str>
<str name="fmap.a">links</str>
<str name="fmap.div">ignored_</str>
</lst>
</requestHandler>
I tried copying that extraction directory into both these directories: /usr/share/maven-repo/org/apache/solr/ /etc/solr
in hopes that either was the 'home' solr directory, no luck.
I added
<lib dir="/var/lib/solr/contrib/extraction/src/java/org/apache/solr/handler/extraction" />
to my solrconfig.xml and observed this in tomcat logs:
INFO: Adding 'file:/var/lib/solr/contrib/extraction/src/java/org/apache/solr/handler/extraction/ExtractingRequestHandler.java' to classloader
Still, no luck.
Thanks in advance.
Edit:
I checked my tomcat logs and I see the following:
Nov 23, 2014 12:53:44 AM org.apache.solr.core.RequestHandlers initHandlersFromConfig INFO: adding lazy requestHandler: solr.extraction.ExtractingRequestHandler
It's odd because it indicates that a "lazy requestHandler" was created at solr.extraction.ExtractingRequestHandler, which contradicts the error:
Error loading class 'solr.extraction.ExtractingRequestHandler'
If I remove the "startup = 'lazy'" attribute from the config above, when I restart Tomcat, there is an error:
SEVERE: org.apache.solr.common.SolrException: Error loading class 'solr.extraction.ExtractingRequestHandler'
