Building Applications with Solr and Ext JS 4 – No Database Necessary!

Developing rich, cloud ready, data intensive web applications is getting easier by the day. With Apache’s Solr you can easily develop dynamic applications that do not require a database.

In the following example we will show how you can easily and quickly read and write to Solr from a web application developed using the Ext JS 4 library.


Tools


  • Java – JDK 1.6 – [ Download ]
  • Apache’s Solr – [ Download ]
  • Glassfish Application Server – [ Download ]
  • Example schema for this exercise – [ Download ]
  • solr_zen.war – example Web App (including Ext JS4 libraries) – [ Download ]

Setting Up the Environment


  • Install the full JDK 1.6
  • Download Solr and extract to an appropriate directory (for example /apps/solr )
  • Download and install the GlassFish Application Server, accepting all defaults
  • Move both the solr.war (from the Solr download archive) and solr_zen.war to the following location in your GlassFish server: GLASSFISH_INSTALL_DIR/glassfish/domains/domain1/autodeploy
  • Point your web browser to: http://localhost:4848/ to view the GlassFish Admin console.
  • Click “server (Admin Server) > Properties tab > Add Property
  • For “Instance Variable Name” enter: solr.data.dir
  • For “Current Value” enter: PATH_TO_ WHERE _ SOLR_ARCHIVE_EXTRACTION/apache-solr-3.4.0/example/solr/data
