Hi Kenan! I prepared sample project with sample MyTransformer class. Sample project will start in-memory H2 database server. Populate some data, load from db and executes some queries.
See DemoStartup class. MyTransformer works as expected. PojoTransformerDemo.zip <http://apache-ignite-users.70518.x6.nabble.com/file/n7792/PojoTransformerDemo.zip> You can import pom.xml in Idea (or other IDE) and play with project. You may change DataSourceFactoryH2 to connect to you Oracle DB and change MyTransformer to handle CLOB fields. Hope this help. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Argument-Type-Mismatch-for-Oracle-CLOB-tp7748p7792.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
