hi Vasiliy, Alexey, I tried this code "cache.loadCache(null,InventoryOrdersKey.class.getName(), "select * from inventory_orders");" and getting different error log ignite-19d380e7.log <http://apache-ignite-users.70518.x6.nabble.com/file/n7430/ignite-19d380e7.log>
Also I have added constructors in "InventoryOrdersKey" as below: public InventoryOrdersKey(){ } public InventoryOrdersKey(Integer itemId){ this.itemId = itemId; } Error now is: "Caused by: javax.cache.integration.CacheLoaderException: Failed to construct instance of class: org.infocepts.ignite.hiveCache.InventoryOrdersKey" -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/javax-cache-CacheException-Failed-to-find-mapping-description-tp7350p7430.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
