Dear LAS people,
I'm getting return code 500 from /las/rpc and thus I ask for your help.
Apache Tomcat is 7.0.35
JVM is 1.6.0_25-b06 Sun Microsystems Inc.
LAS is 8.0
All xml given to las.xml are produced by addXML.sh
You can access the application at http://utmea.enea.it:8080/las_waves
The errore occurs whenever I choose any second dataset in the "data set" window.
Each of my datasets is properly plotted when it is used alone (in las.xml), but when las.xml contains more than one of those datasets, selecting any
of the non default one (which is already plotted) it returns the error: "server request failed: 500 The call failed on the servere; see server log for
details"
Anyway, this are my logs, and later on are las.xml and datafiles' xml.
Thanks for any help,
Emanuele Lombardi
in /tomcat/logs/localhost_access_log.2013-11-29.txt I get:

in /tomcat/logs/localhost.2013-11-29.log I get:
