---------------------------------
Summary: Improve parameter initialization, validation and logging
for the CAS-Product JAXRS service
Key: OODT-651
URL: https://issues.apache.org/jira/browse/OODT-651
Project: OODT
Issue Type: Improvement
Components: product server
Affects Versions: 0.7
Reporter: Ross Laidlaw
Assignee: Ross Laidlaw
Priority: Minor
Fix For: 0.7
My mentor Rishi Verma noted on OODT-649 that several components used by the new
CAS-Product JAX-RS service, such as the file manager client and working
directory, are being initialized in the resource classes for every HTTP
request. This is inefficient and causes unnecessary overheads, since these
parameters (e.g. file manager URL and working directory location) are assumed
to be constant while the web application is running (i.e. if they do change,
the web application can be restarted to pick up the changes) and separate file
manager client instances aren't required for each request.
Instead it would be better to initialize certain parameters only once when the
web application is started up and share them between the resource classes.
Rishi also suggested that additional validation and logging would make the
application more robust and would help developers and users when configuring
the web application.
