Configure Solr -home parameter in dspace and enable changes to be affected

Question

I have a fresh Dspace 1.7.0 installation on windows server 2012, and i got the "dreaded" internal system error.My research led me to believe it was a solr configuration issue. I tried to access the solr folder using the url:

  http://localhost/solr

and i got the following error:

Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: false in null ------------------------------------------------------------- java.lang.RuntimeException: Can't find resource 'solrconfig.xml' in classpath or '${dspace.dir}/solr\conf/', cwd=C:\Program Files (x86)\Apache Software Foundation\Tomcat 8.0 at org.apache.solr.core.SolrResourceLoader.openResource(SolrResourceLoader.java:262) at org.apache.solr.core.SolrResourceLoader.openConfig(SolrResourceLoader.java:230) at org.apache.solr.core.Config.(Config.java:101) at org.apache.solr.core.SolrConfig.(SolrConfig.java:130) at org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:134) at org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:83) at org.apache.catalina.core.ApplicationFilterConfig.initFilter(ApplicationFilterConfig.java:279) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:260) at org.apache.catalina.core.ApplicationFilterConfig.(ApplicationFilterConfig.java:105) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4574) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5193) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:725) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:701) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:717) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:1101) at org.apache.catalina.startup.HostConfig$DeployDirectory.run(HostConfig.java:1786) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

I checked for the solrconfig.xml file,and found it in the

C:\dspace-1.7.0-src-release\dspace\target\dspace-1.7.0-build.dir\solr\search\conf

Further research indicated that i have to edit the solr.xml file to set the solr.home parameter to the value above.

My current solr.xml file,contains just these few parameters:

   <solr persistent="false">
   <cores adminPath="/admin/cores">
   <core name="search" instanceDir="search" />
   <core name="statistics" instanceDir="statistics" />
  </cores>

  </solr>

I need help on the following areas:

1)How to set solr parameter. is it something like

<solr/home="C:\pathto tomcat" />

?

2) What command(s) will i issue to make Dspace begin recognising these parameters?.

Thanks

That looks odd, the target directory you mention is just an intermediate step in the build process, it's not actually used when running DSpace.

To me it looks like you skipped a step of the DSpace build process: you ran maven (that's what generates the target directory) but you did not run ant (that replaces variables such as ${dspace.dir} and copies everything to the right place).

Please review the DSpace installation instructions and make sure you run step 8.
