Re: [las_users] LAS Server Error: javax.servlet.ServletException,still doesn't work

[Jonathan Callahan <Jonathan.S.Callahan@xxxxxxxx>]

Eleni,

I typed 'ThreadPool" into our LAS mail archive search and may have come 
up with the solution to your problem:

http://ferret.pmel.noaa.gov/Ferret/LAS/Mail_Archives/fu_2005/msg00286.html

Let us know if this does or does not solve your problem.
