Replace Options class with PropertyService
Two changes to Metacat Harvester implementation:
(1) Removed call to deprecated Thread.stop() method. Added boolean class variable, Harvester.keepRunning. When the thread is destroyed, set Harvester.keepRunning to false.
(2) Access the harvestList.xsd schema file by finding it locally in the web application rather than via a URL to cvs.ecoinformatics.org.
Remove CR characters from end of line. Formatting changes only, no functional changes.
Implement a new HarvesterServlet for running Harvester as a servlet. This eliminates the need to run Harvester in a terminal window. By default, the HarvesterServlet is commented out in lib/web.xml.tomcat(3,4,5). The user documentation will be modified to instruct Harvester administrators to uncomment the HarvesterServlet entry.
