Metacat has had problems with threading issues when accessed from ecogrid. These problems may stem from the use of shared global variables within the servlet that are not protected against threading problems. We used a lot of these, which I am eliminating in this commit. Besides final variables used as constants (which are not a problem), now there are only three unprotected variables (sessionHash, logMetacat, and conn) which are harder to eliminate. I will be discussiong this with Sid tomorrow to see how to eliminate them.
