i'm developing application using java & mysql database, application desktop application working in network environment. application has static content loaded database when starting application. if super user made change variables, need enforce network users restart application can load new variables. what idea or code need use. you implement this. observer pattern or maybe can have "configtable" in database, property, value, expiration time. so, when admin updates value, other applications in network can pool new value. take jgroups regarding pooling approach, (we don't have enough information give best solution) try this. a notification_table id, event (event know, maybe load new images, etc) workflow 1) clients pool table every x seconds, filtering id > lastnotificationid (that needs saved in local file) 2) client applies new events. 3) client updates local file new notificationid.

i using geomesa 1.1 connect accumulo 1.6.2 java. have no problems querying database specific attributes (specific column values). when try run range query (tried both time , geometric ranges) error. when check accumulo logs see error: exception while doing multi-scan java.lang.arrayindexoutofboundsexception: -1 but none of code uses arrays. exception thrown underlying library. this how constructing cql filter: filter cqlfilter = cql.tofilter("bbox(where, 160.0, 1.0, 170.0, 3.0)"); what might causing java.lang.arrayindexoutofboundsexception: -1 ? edit updated question , answer make clear isn't duplicate , provide more general future visitors. as quick note, looks might using geomesa accumulo quickstart. geometry field there named 'where'. if update filter filter cqlfilter = cql.tofilter("bbox(where, 160.0, 1.0, 170.0, 3.0)"); it may work you.
