Running the testbed

apps/testbed conf/testbed/tutorial-application.xml

What happened?

1. 197 text files and 127 image files where extracted from the arc files located
   in corpora/examples/smallarc and copied to devapps/example/data/lkxml/
2. The OpenNLP and SST analysis tools were run on all 197 text files with the output stored to devapps/example/data/lkxml/
3. HTML visualization files for the analysis were created in devapps/example/data/html/
4. The resulting analysis was converted to a solr compatible index file created in devapps/example/data/solr/
5. This file was fed to the solr index

How did this happen?

The processing was controlled by the conf/testbed/tutorial-application.xml configuration file. We will learn how to modify this file in future sections.

Deploy the web application

ant deploy-testbed

Now a solr server has been started at http://localhost:8983/solr and a web application is running at http://localhost:8983/testbed
