Re: Java exception

[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Phil,

If you have already tried this then I will dig deeper for other things 
to try, but my experience indicates that this error crops up most often 
when the JVM and Java compiler versions are out of sync.  The 
distribution las.war file was built with 1.4.2_02 (two tweaks later than 
your).  I suggest you stop the servlet container, remove the webapps/las 
directory and las.war file and build new war file ('ant dist' in the 
las_servlet directory) and restart the servlet container.

Let me know what happens or if you are using a .war that you built locally.
